I simultaneously traverse countless worlds

If these Japanese elites knew that becoming a demon would grant them immortality, they wouldn't care about relying on cannibalism to maintain their longevity. In the past, their path to wealth and power was essentially the same: they ate people in another way. If demons ate people, it would just be a bit more direct. And if the Demon King Muzan Kibutsuji did something like that, becoming the mastermind behind Japan would be no problem at all. What would a Demon Slayer Corps be?

Even if Yoriichi Tsugikuni, a powerhouse of BUG level, were to be resurrected, he would still be defeated by the power of a single nation like Japan. The Pillar-level powerhouses of the Demon Slayer Corps, when facing a modern army, could at most choose a way to die a less gruesome death. As for the other swordsmen and members of the Demon Slayer Corps, there is no need to mention them; they would have no resistance against the encirclement and attack of the Japanese army.

The network of relationships cultivated by the Demon Slayer Corps and the Shinto priests makes them utterly insignificant compared to the Japanese nobility who crave immortality. Just look at the absurd actions of emperors throughout Chinese history who pursued immortality, and you'll know the extent to which the Japanese nobility would go for it. Defects like cannibalism and the inability to see sunlight are no problem when it comes to immortality. And if the Japanese nobility were to turn into demons, the spectacle would be truly outrageous.

What made the ghost god Li Mo feel somewhat regretful was that the original Demon Slayer anime was clearly unlikely to depict such a scene. Otherwise, Demon Slayer could simply be renamed Pillar Slayer, and the Demon Slayer Corps and even the protagonist, Tanjiro Kamado, would all be wiped out and killed. That quintessential hot-blooded anime would instantly become dark and desolate...

"But can we use the [Primordial Demon Blood] now?"

While the demon god Li Mo was still letting his thoughts wander, Shinobu Kocho stared intently at the test tube of [Progenitor Demon Blood] that didn't look like anything good. After examining it carefully, she put her hands on her hips and said with some doubt.

"Well, actually, if we want to utilize the [Primordial Ghost Blood], we need to consider how to utilize it. However, it contains the spiritual power of the Ghost King, and we can easily be controlled by it if we're not careful. That's what happened to those evil ghosts!"

Faced with Shinobu's questioning, the demon god Li Mo completely ignored her attitude. He gently put his arm around Kanae's slender waist, waved the test tube of [Progenitor Demon Blood] in front of the three beautiful girls, and then raised it up to the rising sun, giving it a meaningful evaluation.

Last night's experiment on demons involved more than just extracting the Progenitor Demon Blood. He also subjected the demons to various inhumane experiments, confirming some details revealed in the original Demon Slayer anime. For example, most of the demons were unaware of the Demon King Muzan's existence, but mentioning his name would attract Muzan's attention. This was clearly related to the Progenitor Demon Blood, and it also reminded Li Mo of his own methods, such as the Seed of Fusion.

In a sense, the demons created by Demon King Muzan Kibutsuji using the "Progenitor Demon Blood" are somewhat similar to the demons created by Demon God Li Mo and other subordinates fused by Li Mo using the "Seed of Fusion." At most, it's just that Demon God Li Mo's methods don't require turning those subordinates into demons with considerable limitations. However, in terms of control, Demon God Li Mo's control over his subordinates is much stronger than that of Demon King Muzan Kibutsuji.

At least, the Demon King Muzan Kibutsuji needs the [Progenitor Demon Blood] to control his subordinates. The subordinates created by the Demon God Li Mo using the [Seed of Fusion] actually have higher loyalty, but they also seem to be less than respectable!

"And the spiritual power left behind by the Ghost King? Those evil spirits are under his control..."

As soon as the demon Li Mo finished speaking, compared to Shinobu Kocho and Kanae Tsuyuri, who both looked somewhat surprised, Kanae Kocho grasped the key point. She couldn't help but stare at the test tube of [Progenitor Demon Blood], seemingly understanding the Demon Slayer Corps' records of evil demons.

The Demon Slayer Corps had considered capturing a demon to interrogate it about the Demon King and other demons, but these attempts always ended in failure. The demons captured by the Demon Slayer Corps rarely yielded any useful information, and when questioned about the Demon King, those demons who spoke almost never survived. When Kanae Kocho had previously read the records left by the Demon Slayer Corps, she didn't quite understand what secrets were hidden within them, but now she understood what was going on.

It's obvious that it's impossible for demons born from the blood of the progenitor to reveal any secrets about the Demon King, Muzan Kibutsuji. That scumbag boss doesn't care about the lives of those demons; anyone who dares to mention his name or information will be killed by him first!

"That's right! But the control of the [Primordial Ghost Blood] is not absolute. If a being that has become a demon has enough talent and opportunity, it can also break free from the control of the Ghost King!"

Seeing that Kanae Butterfly had immediately grasped the key information, Ghost God Li Mo nodded in approval, corrected his woman's understanding of the [Progenitor Demon Blood], then released his grip and took two steps forward. Turning to look at the three beautiful girls, he held up the test tube of [Progenitor Demon Blood] and slowly explained as he began to work: "Furthermore, if one's strength is sufficient, this [Progenitor Demon Blood] containing the Demon King's spiritual power is actually a very obvious weakness..."

Following Li Mo's words, he opened the test tube of [Primordial Demon Blood] in his hand, separated about half of it, and then carefully put away the remaining half of the [Primordial Demon Blood]. He then held up a small clump of [Primordial Demon Blood] so that Kanae Kocho, Shinobu Kocho, and Kanae Tsuyuri could see it clearly before he began his actions.

In the next instant, the demon god Li Mo used his Yin-Yang Escape power to directly activate the spiritual power hidden within the ball of Ancestral Demon Blood, allowing the Demon King Kibutsuji Muzan, who was far away, to immediately sense the unusual situation!

Chapter 13 A Strikes Out of Thin Air

Buzz——————!

As the ghost god Li Mo acted, the mass of [Primordial Ghost Blood] seemed to be activated, transforming into a black monster that looked like it was baring its fangs and claws, and it wanted to break free of its restraints and pounce on the nearest person.

It should be said that the world of Demon Slayer is not a supernatural world. If it were a supernatural world, and Muzan Kibutsuji, as the Demon King, had lived for over a thousand years, he certainly wouldn't have rashly integrated his spiritual power into the Progenitor Demon Blood, nor would he have arranged any preventative measures within the Progenitor Demon Blood. Apart from the Twelve Demon Moons and a few demons he paid attention to, the Progenitor Demon Blood of other demons was in a semi-hidden state.

Or to put it more clearly, if ordinary demons don't know the name of the Demon King, Kibushi Muzan, and don't utter this title hidden in the [Progenitor Demon Blood], they won't attract his attention at all. And if they do utter the name of the Demon King, Kibushi Muzan, they will be killed by the scumbag boss who is unwilling to reveal his information, directly through the connection of the [Progenitor Demon Blood]. Only the Twelve Demon Moons and a few other demons can contact the Demon King without being killed casually.

In the world of Demon Slayer, Muzan Kibutsuji's actions are not too problematic. Except for one woman who became a demon and escaped his control by exploiting the flaws in the "Original Demon Blood," other demons, even those who know Blood Demon Arts, cannot escape the limitations of the "Original Demon Blood." Even if Yoriichi Tsugikuni were to be resurrected, he would still find it difficult to capture Muzan Kibutsuji, let alone use the "Original Demon Blood" to kill him—something completely beyond his capabilities.

However, for Li Mo, a knowledgeable and experienced demon god who has mastered the extraordinary power systems of other worlds, the spiritual power left behind by the scumbag boss Kibushi Muzan in the [Progenitor Demon Blood] is an obvious target. Once activated, it can find the real target!

"This...this thing is still alive?!"

Seeing the grotesque, distorted form of the Progenitor's Blood, Shinobu, who had been standing at the front, couldn't help but take a half-step back. Her face tightened as she stared intently at the grotesque Blood, unconsciously gripping the hilt of her katana. While asking her lover about the creature's secrets, she was also prepared to dodge and deliver a slash at any moment.

Not only was Butterfly afraid, but even Butterfly Kanae and Tsuyuri Kanao, looking at the constantly twisting and deforming mass of [Progenitor Demon Blood], were on high alert and ready to attack. They didn't want to be stuck to themselves by this [Progenitor Demon Blood] that looked like it was something bad!

"The [Primordial Demon Blood], which is not alive but is influenced by the Demon King's spiritual power, will turn any evil spirit that uses it or becomes an evil spirit into the Demon King's subordinate!"

The well-versed ghost god Li Mo didn't even blink at the activated [Primordial Ghost Blood]. He showed no fear whatsoever at this small scene before him. Calmly suppressing the activated [Primordial Ghost Blood] with his own power, he briefly explained it to the three beautiful girls, and then, looking at the mass of [Primordial Ghost Blood], he sneered: "The problem is, if you're facing a countermeasure, this [Primordial Ghost Blood] is a weakness that allows the opponent to launch an attack..."

When he said these words, the aura of the ghost god Li Mo suddenly changed. Kocho Kanae, Kocho Shinobu, and Kurihana Kanao, who were close to him, all felt a sudden weight in their hearts. They felt as if they were being pressed down by mountains and could not breathe. They also felt a sense of crisis that they might be crushed to pieces at any moment.

At this moment, Ghost God Li Mo had already activated the [Soldier's Edge Technique] he obtained from the Doomsday Wolf World. This extremely rare mental martial art depends entirely on the individual's performance. For example, the Red Warriors of the Doomsday Wolf World, who had experienced the Long March of 25,000 li, possessed a terrifying level of unwavering willpower that allowed them to challenge opponents of higher levels. Ghost God Li Mo, having fused many of his own soul and physical powers, also had an outstanding effect when activating the [Soldier's Edge Technique]. It was even more suitable for mental attacks at this moment.

The demon god Li Mo clenched his right fist and then swung it out. The onlookers, including Kocho Kanae, had a strange illusion. They seemed to see countless warriors fighting fiercely on the battlefield, their blood staining the ground. However, the demon god Li Mo knew that his punch was based on his own experience in the world of late Qing Dynasty films and television dramas. His indomitable will to conquer the world by leading thousands of troops was directly used to deliver a vicious blow to Kibushi Muzan out of thin air through the [Progenitor Demon Blood].

In the next instant, the mass of [Progenitor Demon Blood] vanished without a trace, and everyone, including Kanae Kocho, Shinobu Kocho, and Kanao Tsuyuri, seemed to hear a faint, shrill scream, followed by a complete silence.

……

Rewind to a dozen seconds earlier, in Tokyo, the capital of Japan.

As a replacement for the Tokugawa Shogunate, Japan has now established its capital as Tokyo, rather than Kyoto, the former capital of Japan before the Shogunate, because Tokyo, formerly known as Edo, is actually more suitable as Japan's capital.

After all, in the feudal era, Kyoto was not an exaggeration to be the capital of Japan. It was located in a region close to the Japanese inland, surrounded by plains and with enough food to support the population of Kyoto and allow it to expand outwards. However, in the industrial era, Japan's tragically low resource content, which is like a museum of minerals, could not provide enough industrial resources for Kyoto. It was necessary to place them in port cities suitable for maritime transport.

For example, the Yawata Steel Works established by Japan was located in the coastal area of ​​Kyushu Island near Fukuoka, in order to obtain iron ore, refined coal and other materials from overseas more quickly. Otherwise, given Japan's penniless imperialist style, they would not have been willing to invest more money in its construction if it had been located inland.

As the capital city of Japan, Tokyo has become the most prosperous and densely populated area in Japan over the centuries since the Japanese Shogunate. As an important port area near the Pacific Ocean, it has naturally received a lot of attention and development. Of course, modern Japan cannot be compared with the Japan of the second largest economy. It can be said that Tokyo is now mostly made up of wooden and bamboo houses, with occasional reinforced concrete buildings that are relatively rare.

In terms of population, Tokyo alone, including the core city of Tokyo and its surrounding areas, has a population of over four million, which is the size of a major city on an international scale. In addition, many powerful figures and dignitaries reside in Tokyo, and officials and wealthy people are concentrated in this city. It is an economically prosperous city with a large flow of people, which naturally attracts some intelligent evil spirits to sneak into Tokyo.

For example, the Demon King Muzan Kibutsuji hides in Tokyo. He never goes out to wander around during the day. At night, he chooses his targets and sometimes even disguises himself in various forms, living quietly among humans for a long time.

"Huh? That idiot dared to call me by my name..."

In a mansion purchased by a wealthy foreigner in Tokyo, the Demon King Kibushi Muzan, who had just devoured the male owner of the wealthy family a few days ago and impersonated him to seize his wealth and wife, suddenly frowned and seemed somewhat unhappy.

For a scumbag like Muzan, there's no reason to consider things like taking care of his subordinates. The only ones he really values ​​are the Twelve Demon Moons and a few other demons. The other demons are just tools he created, used occasionally to test if the Demon Slayer Corps still has any strong members. Otherwise, he just lets them run wild.

In this hands-off situation, expecting Muzan Kibutsuji to have any sense of responsibility for the demons he created is nothing short of wishful thinking.

The demon subordinates that the Demon King Kibushi Muzan takes seriously are the Twelve Demon Moons and Nakime, who is always at his service. Other demons, even those with outstanding talent or those who have eaten too many people and know blood demon arts, are just cannon fodder that he can throw away at will, unless they interest him.

Even among the Twelve Demon Moons, anyone who dares to displease Muzan Kibutsuji will suffer a terrible fate. In reality, he values ​​the six highest-ranking demons of the Twelve Demon Moons, each of whom has existed for at least a hundred years or even several hundred years. Occasionally, one or two of the six lower-ranking demons will be surrounded and killed by the Demon Slayer Corps. At most, he will only pay attention to them occasionally. As for those evil demons he created with the blood of the progenitor demon, at most, they must perform exceptionally well to catch the Demon King's attention and be promoted.

The scumbag boss, Kibushi Muzan, values ​​promoting ordinary demons, except when the Twelve Demon Moons are reduced in number. Otherwise, it's because they know the name of the Demon King, Kibushi Muzan, and accidentally mention it in front of other demons or Demon Slayer Corps members, angering the scumbag boss so he can kill that idiot. Now, the scumbag boss senses the movement of the [Progenitor Demon Blood] he separated and thinks that another such fool is courting death.

The problem is that Muzan Kibutsuji has no idea that what he is facing this time is not an evil spirit controlled by his [Progenitor Demon Blood], but a top-level powerhouse who is scheming to use the special properties of the [Progenitor Demon Blood] to prepare a ruthless attack on him!

"Wait? What is this—ah!!!"

When the Demon King, Kibushi Muzan, failed to connect with the mass of [Progenitor Demon Blood], and was wondering what had happened to him that he couldn't connect with this evil demon who dared to call out his name, he suddenly felt an extremely terrifying sense of danger. The next second, it was as if he had been struck by an invisible blade, and was cleaved in two from the head in a severe wound.

Zizi!

When the demon god Li Mo used the [Soldier's Edge Technique] to activate the power of [Yin Yang Escape] and unleashed this invisible attack transmitted through [Primordial Demon Blood] with his spiritual power, the unsuspecting Demon Dancer Muzan suffered a severe blow.

With the faint sound of blood spurting and scattering around, Kibushi Muzan, dressed in a men's kimono yukata, was trying his best to restore his two-part body. His body, which appeared to have been cut in two by a sharp blade, was now growing fleshy buds from the wounds, trying to close up. However, every time it was about to close up, the fleshy buds would inexplicably break off again, preventing his body from being restored.

At first glance, Muzan Kibutsuji's current situation resembles a scene from a horror movie, specifically a restricted horror movie mixed with gory scenes. Not only are his two severed bodies still moving, but the blood on the ground is even trying to flow backward and return to its original state.

If the injuries were merely caused by cold weapons or even the Nichirin Blade, Kibushi Muzan would not have suffered such a horrific scene. This cowardly and despicable boss, the Demon King, had developed his survival abilities to the extreme over the past thousand years. Even the Nichirin Blade's head-severing technique could not directly kill Kibushi Muzan. However, this time Kibushi Muzan encountered a supernatural power system from another world, and the severe mental trauma directly manifested in his body.

The attack unleashed by the demon god Li Mo with the [Weapon Edge Technique] directly penetrated the mass of [Primordial Demon Blood], inflicting a severe blow on the mental state of Kibutsu Muzan. Completely unprepared for this attack, Kibutsu Muzan's injuries were not as severe as those in the Hand Demon, whose soul was severely damaged. However, the mental wound inflicted by the [Weapon Edge Technique] directly affected Kibutsu Muzan, as if he had been severed in two by an invisible blade and was unlikely to recover.

For an ordinary strongman, the severe injuries resulting from this invisible attack would likely be fatal. However, Muzan Kibutsuji is, after all, a demon king. Even if he seems weak compared to many powerful villainous bosses, his extraordinary regenerative abilities ensure he won't die from this, as evidenced by the fact that his two severed bodies are working hard to recover.

For Muzan Kibutsuji, the injury he suffered was certainly troublesome, but fortunately it did not involve the soul level and was at most a mental level. Even so, he would need to spend a lot of time and energy to recover from this sudden and inexplicable serious injury.

"Honey, what happened? Oh no!!!"

As Muzan Kibutsuji struggled to recover his body, a strikingly beautiful young woman anxiously opened the door. This young wife, who had just run over after hearing her "husband's" screams, was terrified by Muzan Kibutsuji's gruesome state and screamed before being swallowed whole by several tentacles.

Although severely injured by the special attack methods of the demon god Li Mo, Kibushi Muzan was only seriously injured. A young woman who had eaten her husband and was disguised in the house was no match for the injured Kibushi Muzan. The seemingly beautiful young woman was directly eaten by Kibushi Muzan with tentacles extending from her body, leaving not even her clothes behind. The two servants who were with the young woman were so frightened that their legs went weak and they screamed.

At this point, Muzan Kibutsuji, who was in a state of impotent rage and unaware of what had happened, knew that his identity had been exposed and that he could not spare them. Just like the same things he had done over the past thousand years, many people did not know before they died that their relatives had actually been eaten by Muzan Kibutsuji. The only reason to spare them was to experience a different life and to serve as food reserves left by Muzan Kibutsuji.

Soon, several faint screams were heard from the manor, but Kibushi Muzan, who had specially ordered the installation of barriers and trees, used the manor's omnipresent shadows to eliminate everyone, and then hid in the basement and dug his way out!

……

"Mo, is that all?"

Meanwhile, at the camp near Fujikasane Mountain, Kocho Kanae, gazing at the now-vanished [Progenitor Demon Blood], felt the danger that had been rising in her heart dissipate and relax. Unusually, she looked at her lover with curiosity and asked him a question.

Not only Kanae Kocho, but also Shinobu Kocho and Kanao Tsuyuri were very interested in this question. Even though they had already received the enhanced training from the Demon God Li Mo, in terms of the extraordinary power training from internal energy cultivation to Qi and blood martial arts, the level was not significantly different from the breathing techniques they had learned before. Suddenly discovering the special methods used by the Demon God Li Mo, it would be a lie to say they weren't curious. Moreover, since the Demon God Li Mo had just launched an attack from thin air using the [Ancestor Demon Blood], they were even more curious about the effect of this attack.

Most importantly, Kanae Kocho, who was once the Flower Pillar of the Demon Slayer Corps, wanted to know how much damage her lover had done to the Demon King who created the demons. It would be even better if she could kill the progenitor Demon King in one fell swoop!

"Well, I would say it has achieved the expected results. The Primordial Ghost King's regenerative ability is still very strong. At most, this will only injure him, not kill him..."

Seeing the slightly expectant look in Kanae's eyes, Ghost God Li Mo shook his head with some regret and explained the approximate effect of the attack he had just delivered with the [Soldier's Edge Technique]. That mental attack could deal a heavy blow to the scumbag boss Muzan Kibutsuji, but thinking that it would kill Muzan Kibutsuji was wishful thinking.

To be fair, Ghost God Li Mo's strength hasn't reached the level where he can kill Muzan Kibutsuji from a distance. Even if he merges the power and memories of more than ten different Li Mos, killing a villainous boss with super regenerative abilities directly with a mental attack is still beyond Ghost God Li Mo's current strength. If he were to merge the power of several Li Mos from higher-level worlds, or raise the power of [Yin Yang Release] to another level, he could try to see if he could achieve that level.

Now, Ghost God Li Mo is certain that with the scumbag boss Kibutsuji Muzan's super strong recovery ability, he should be able to withstand this attack without any problem. At most, he might suffer a little loss because he is not familiar with mental attacks. Hearing her lover's explanation, Kocho Kanae was somewhat disappointed, but she did not say anything else. Even Kocho Shinobu and Tsuyuri Kanae did not suggest that their man launch another attack.

However, what the demon god Li Mo and the group led by Kocho Kanae were unaware of was that the scoundrel Muzan Kibutsuji, who had inexplicably suffered a severe injury, was currently trying to heal his wounds while simultaneously scaring himself with his own imagination...

Chapter 14 Ghost Dance Tsuji Muzan’s Panic

Dozens of kilometers away from Tokyo, in an underground cave formed by volcanic activity, the still terrifying two halves of the Demon King Muzan Kibutsuji's body appeared. The two halves were barely connected by fleshy buds, but they still could not be restored to their original state immediately.

At first glance, the Demon King Muzan Kibutsuji's current form is still roughly recognizable as human, but the sharp cuts from his forehead to his legs are still held together by fleshy buds. In fact, many of these buds break off and fall off when they are connected, only to be absorbed back into Muzan Kibutsuji's body. His appearance is so peculiar that it resembles a monster from a supernatural horror movie, only slightly better than the dismembered corpse he had previously looked like in a horror film.

With his supernatural, monstrous appearance, Muzan Kibutsuji doesn't need any Demon Slayer Corps intelligence personnel to confirm whether he's a demon. Any ordinary person with normal intelligence would probably turn and run away immediately upon seeing him, or rush to report to the nearest Japanese police that they've discovered a terrifying monster!

In any case, it's hard for ordinary people to believe that a so-called "person" that looks like two corpses pieced together and moving around could be a harmless thing. Whether it's feudal superstition or current science, no one would think that such a being could be benevolent. Ordinary people with normal intelligence would run away or call the police immediately if they saw the current Demon King Muzan Kibutsuji. They would never attempt to do anything as suicidal as trying to communicate with Muzan Kibutsuji.

In fact, at this moment, the Demon King Muzan Kibutsuji was well aware of his situation. Without any hesitation, he had just killed the wealthy family and servants he was disguised as. Using the flesh and blood he had absorbed, he directly reassembled his two bodies and forcibly left Tokyo through the underground passage. Only after running here did he stop to rest.

Once the Demon King Kibushi Muzan confirmed that there was nothing wrong with the cave, he simply closed his eyes and stood still. His two body segments, connected by flesh buds, were getting closer and closer. Although the flesh buds that were constantly merging together were falling off and being absorbed from time to time, the frequency of those falling flesh buds was getting lower and lower. The two body segments, which looked as if they had been severed and were connected by flesh buds, were gradually closing together. It was clear that the Demon King Kibushi Muzan was able to recover from this kind of injury. With his first thought of preserving his life, he had developed an outstanding ability to preserve his life in this regard.

About an hour later, the two parts of the Demon King Kibushi Muzan's body finally fused together again. The fleshy buds did not fall off and instead successfully fused the two parts of the body together. Apart from the Demon King Kibushi Muzan's face looking a little pale, there were no visible injuries on his body. It can be said that his recovery ability was truly outstanding, even completely erasing the mental trauma he had suffered.

At this moment, the Demon King Kibushi Muzan opened his eyes. He used his extraordinary regenerative ability to heal his injuries. Even though it was quite costly, he was able to recover by eating people. He has now recovered from his injuries and is not in danger. Instead, he is able to think about what exactly happened!

"Damn it, what just happened? Was it some kind of special Blood Demon Art? Or did another terrifying guy like Yoriichi Tsugikuni appear on the human side...?"

When the Demon King Muzan recovered, he found that his clothes were completely torn and his face turned pale. He then made a kimono out of his own skin. This was the Demon King who had always enjoyed a life of luxury and luxury, but now he had to hide in an underground cave. He racked his brains to recall what had happened that had almost caused him to die on the spot.

What exactly happened just now?

This was obviously very difficult for the Demon King Kibushi Muzan to guess the real situation. After all, he was not a wise man who truly knew about the system of supernatural powers, and he was an ancient person who might not even know the concept of another world. The way that the demon god Li Mo struck out of thin air was beyond his understanding.

Even ancient sages would be completely bewildered if you talked to them about modern tactics like asymmetric decapitation. They wouldn't understand what you were talking about at all. Similarly, the contents of supernatural power systems are so complex that even if someone hears them, they won't know the meaning of the hidden terms. Some unknown methods are completely incomprehensible, let alone how to prevent them or even know they exist. As for the Demon King, Kibushi Muzan, he could only try to find the reason for the sudden and inexplicable attack from his existing common sense.

After all, Demon King Kibushi Muzan had never read any time-travel or fantasy novels. Even though America had already produced the earliest time-travel science fiction stories, Demon King Kibushi Muzan obviously didn't read the science fiction works published by America. Naturally, he first suspected that some evil spirit had used a special blood demon technique on him, or that another overpowered human like Yoriichi Tsugikuni had appeared.

As for the former, the reason why the Demon King Kibushi Muzan would have such suspicions is because he has only seen that the Blood Demon Art of evil demons has many extraordinary elements. For example, the breathing techniques of the Demon Slayer Corps are actually just that, and they cannot cause serious injury to oneself out of thin air. However, those evil demons who know Blood Demon Art are not without the idea of ​​rebelling against their superiors.

In any case, Japan's tradition of subordinates overthrowing their superiors has a long history and a solid foundation. Whether it's Japan's strict social hierarchy or the unavoidable hierarchical system of one level suppressing another in the military, politics, and even a company, subordinates who disagree with their superiors' decisions are seen as challenging and suppressed. They may even face sanctions from other superiors. As a result, other subordinates are eager to participate but find it difficult to do so. Only when a subordinate successfully overthrows their superior will they be viewed differently by everyone.

Among demons, Muzan Kibutsuji, as the Demon King, has carried forward the feudal system of Japan. Apart from the Twelve Demon Moons and a few demons who have mastered special blood demon arts, who are at least valued by him and allowed to have a certain voice, the life and death of all demons are actually in his hands. Otherwise, there would be no reason for demons to try so hard to break free from the shackles of the "Progenitor Demon Blood" and not want to put their life and death in the hands of others, especially not in the hands of the scumbag boss, Muzan Kibutsuji.

Therefore, if a demon, feeling confident in its power, were to use Blood Demon Art to stage an underdog victory, the Demon King Kibushi Muzan wouldn't find it strange. However, he wasn't sure if it was a specific demon's Blood Demon Art, or even if he were certain it was, he wouldn't dare to punish it rashly.

As for whether he is a bug-level powerhouse similar to Yoriichi Tsugikuni...

Even just recalling the terrifying figure from hundreds of years ago, wielding a crimson Nichirin Blade and unleashing over 1,500 slashes in an instant, nearly killing him, made the Demon King Kibushi Muzan shudder, his face turning deathly pale.
