Crossover Anime: I Became Invincible Starting as an Ajin

Chapter 86: Vagabond & Demon Slayer

Shinmen Musashi was taken aback, not expecting that the other party could see through his existence as not being from this world as soon as he opened his mouth.

This is something that even those blond foreigners don't know.

Shinmen Musashi became curious about the person in front of him: "Don't worry, I won't kill you. I hope you have enough strength to protect your own life."

Wang Bai looked puzzled. What gave him the confidence to defeat him?

The next second, Shinmen Musashi moved, his katana drawing a chilling arc.

Wang Bai felt as if a blade of light appeared out of thin air before his eyes, splitting him in two from top to bottom.

The tearing sensation felt incredibly real, like the tentacles of death sweeping through his brain: the pain, fear, and illusions of ending left Wang Bai momentarily disoriented.

No, that's not right!

However, as a demi-human, Wang Bai instantly realized something was wrong. Such injuries should have triggered an immediate resurrection after death, rather than leaving him stagnant on the verge of death.

When Wang Bai realized this, the scene of his injury vanished from his sight, turning into an illusion.

What comes into view is the real Shinmen Musashi.

The blade in his hand slashed straight at the location in the illusion.

But this time, it only produced a metallic clang.

With Wang Bai's current magic power and magic level, he could completely strengthen his body to the strength of an alloy.

Shinmen Musashi looked at Wang Bai, who was completely unharmed, and was not only amazed by Wang Bai's physical strength, but also by the fact that Wang Bai had actually stepped out of the killing intent.

But instead of retreating, Shinmen Musashi advanced, and a stream of black fire swept across the blade, seemingly imbuing it with some mysterious power.

The sharp blade actually cut through Wang Bai's skin, and a trickle of blood seeped out.

Wang Bai frowned. He activated the healing magic, but the wound did not heal, as if there was a wound on his body itself.

Wang Bai was surprised, even if the opponent's blade had been imbued with some kind of sharpness, greatly enhancing its lethality.

This would be a huge threat to an ordinary magician, but for Wang Bai, this injury was nothing.

However, it left behind a wound that could not be healed by magic.

Wang Bai immediately attempted suicide once, experiencing the process of his body recovering.

The wound remains in the same place.

Wang Bai frowned; he sensed the problem.

This injury seems to be affecting the mind.

The resurrection of demi-humans lies in the combination of the power of the mind and the third law. Now, Wang Bai believes that he has a wound in his mind. When the wound actually appears in his body, he will naturally accept its existence.

Even if one is resurrected through suicide, the wound remains.

"That's really interesting. What's the name of that move you made?!"

Shinmen Musashi was so shocked that he couldn't speak, even though he hadn't recovered to his peak condition.

The combined power of artistic conception and the power of Blood Demon Art only caused the opponent a slight injury?!

Even the most terrifying demons must perish within the realm of imagination.

This unscientific!

But the next second, a tremendous force slammed into his head, and his vision and consciousness went blank.

After a while, Shinmen Musashi awoke from the remaining body, and a new brain continued to grow.

He looked at the minced meat around him and swallowed hard.

His head was smashed to pieces with just one punch; he didn't even see how the punch was thrown!

Having been in this world for so long, I've seen many demi-humans and so-called black ghosts, but none of them have such outrageous strength.

How dare those so-called government officials oppose such a terrifying guy?

Don't people in high positions feel any sense of crisis about their heads being moved at any time?

The battle ended in an instant, and Shinmen Musashi immediately realized that he was no match for the person in front of him.

Wang Bai looked at Shinmen Musashi: "Now you can properly introduce yourself, right?"

"And how did you come into this world?"

Shinmen Musashi's mind raced: "Could it be that you, too, came to this world from another world?"

Wang Bai was speechless; the new Musashi in front of him seemed unable to see the current situation clearly.

With a flick of his fist, Shinmen Musashi lost his entire lower body.

"My name is Shinmen Musashi, and I don't know how I got to this world."

"In my original world, I was walking a path of unparalleled power, but then suddenly a creature called a 'demon' appeared, and at the same time, the name of the Demon King, Muzan Kibutsuji, came to mind."

"In the battle against the demons, I was infected by their blood and became a demon myself."

"Afterwards, when I was about to lose control and start killing people, I met a monk who enlightened me and helped me understand a bit of the essence of the art, which completely suppressed my desire to eat people."

"However, I have also become inseparable from blood. But I assure you, even when I consume blood, it is only with the permission of humans, or as a reward for helping others complete tasks."

"Once I become unparalleled in the world, I will discard this demonic body and re-enter the cycle of reincarnation!"

After hearing Shinmen Musashi's words, Wang Bai immediately thought of a world called Demon Slayer.

After all, the name of Muzan Kibutsuji is that of the final boss, so it is naturally memorable.

At the same time, Wang Bai roughly guessed where Shinmen Musashi came from by using the terms "artistic conception" and "unparalleled in the world".

To confirm, Wang Bai asked, "Next, I'll ask you questions and you answer?"

Shinmen Musashi paused for a moment, then nodded.

"Weren't you originally from a village called Miyamoto?"

"Yes—how did you know?"

"Do you have a good friend named Hon'ita Matahachi?"

"Yes."

Have you ever met a monk who called himself Monk Ze'an?

This time, however, there was a long silence.

Wang Bai didn't press further. It seemed the other party had met him, but something must have happened.

At this moment, Wang Bai was completely certain that the other party was the protagonist of "Vagabond," which was serialized in a weekly magazine in 1998.

But why is the character of Vagabond connected to a character from the Demon Slayer world?

Moreover, judging from the combat power in the Demon Slayer world, they would be utterly indiscriminately slaughtering the people in the Vagabond world.

"I think I know something about Muzan Kibutsuji that you mentioned. How did you manage to fight against such an immortal demon?"

Shinmen Musashi looked at Wang Bai with surprise. What the other party said made people subconsciously suspicious, but his confident tone inexplicably convinced them, as if it were the truth.

Put that feeling of surprise behind you. Your life is still in their hands, so just answer the questions honestly.

"Initially, we heard that an immortal demon appeared on the battlefield, slaughtering the generals and soldiers on both sides, with only a few surviving to return and report back."

"However, no one cared at the time, assuming that the soldiers were just making up lies to avoid fighting."

"After all, most people up there don't believe in things like immortality or sorcery."

"But later, more and more people witnessed different evil spirits, and some of these evil spirits even built a new city. They also learned the name of the original evil spirit from these evil spirits."

"Oni King, Oni Wu Tsuji Muzan."

"At the beginning, Muzan Kibutsuji attracted a large population by using his immortality, abundant food, and safe areas that were not affected by war."

"He was even once hailed as a sage who ended wars and saved people from suffering."

"But soon, people discovered that a group of people in the city seemed to disappear every now and then, and some who knew about it died mysteriously before they could even speak out."

Finally, through the desperate investigation of a certain swordsman, the truth of the matter was revealed.

"These so-called immortals actually use humans as food and as consumables for their own pleasure."

"The environment where these evil spirits live can be described as mountains of corpses and seas of blood. The corpses do not decompose due to sorcery, but the terror at the time of their death is still vivid in one's mind."

"When some people began to calculate the approximate number of deaths, they were surprised to find that at least tens of thousands of people had died as a result, a number that several large cities could not reach."

"At this time, people learned the truth, stopped fighting, and began to unite to fight against the evil spirit."

"but----"

"The evil forces have already formed, so the results have been minimal, and their sorcery and immortality are simply impossible to contend with."

"Fortunately, they seem to fear daytime and never move around during the day, which slows them down."

.

"Only masters can slay evil spirits from the heart through their mental state. Even if the body of the slain evil spirit is still alive, its soul is dead."

At this point, Shinmen Musashi was filled with admiration, believing that that was truly unparalleled in the world.

"Later, humanity was left with only one city, and the rest of the territory was occupied by the other side. At this time, a monk discovered a magical stone."

"This stone can actually kill evil spirits directly, turning them into ashes."

"However, during the transport of this stone, the monk was chased by evil spirits. In order to get the stone back to the last city, he sent a boy to escape with the stone while he himself blocked the evil spirits' path."

Shinmen Musashi raised the blade in his hand: "This sword is made from the same stone. Only with a blade like this can one slay demons."

He placed his hand on the blade, as if putting a piece of meat into a frying pan, making a sizzling sound, and wisps of smoke rose from the spot where he touched it.

"Look, even as a demon, I will be slain by this blade."

Shinmen Musashi recounts the various aspects of his despairing world, every word filled with blood and tears, depicting a dark scene of a world ravaged by demons and humanity on the verge of extinction.

Wang Bai listened quietly, and the instinct of the Imaginary Tree resonated with it, conveying its sorrowful wishes and hopes that transcended the world.

[Sacred Prayer, Tragedy Rewritten]

This "fruit grown from the Holy Grail absorbed by the Imaginary Tree" is also the core ability of the Imaginary Tree itself, presenting Wang Bai with a series of tragic scenes.

The monk Takuan was covered in blood, leaning against a broken wall. His staff was long since broken. In front of him were countless evil spirits waiting to devour his flesh. Not a single evil spirit stepped over Takuan to advance.

Outside a lonely city, a massive army of demons surged in like a tidal wave, instantly submerging the city's defenses and warriors like grains of sand on a beach, leaving only a scene of demons reveling in the city with blood and flesh.

In the vast space, large numbers of men and women are forced to mate, fed at set times, and put to sleep at set times, just like livestock being raised, with every second of their lives dedicated to efficiently producing new humans.

Wang Bai took a deep breath, turning his gaze away from those tragic scenes and looking at Shinmen Musashi in front of him.

He could sense that the power of the Imaginary Tree had anchored itself in that world, awaiting only his decision.

"Then," Wang Bai raised his hand, his palm radiating a soft, pure platinum-gold light, the projection of a platinum halo faintly appearing in the sky, "if I were given a chance, would you be willing to change this regret?"

"What?!"

Shinmen Musashi suddenly looked up, his eyes filled with disbelief.

"You can think of the Imaginary Tree as a deity," Wang Bai explained simply to Shinmen Musashi. "Because of the connection we have established, the Imaginary Tree has received the sorrowful wishes of your world."

"It can project power back, attempting to overwrite" a fragment of the past, but this requires coordinates, a powerful prayer as guidance. Your deepest regrets will become the anchor point for locating your world."

Shinmen Musashi was completely stunned by the concepts Wang Bai spoke of. He didn't quite understand most of the terms, but he knew that the other party could help him return to his original world and change the tragedy of the past.

"However, overwriting the past will cause the newly created future to completely overwrite the present future, so..."

"Choose your path: Are you willing to go back in time and change the future?"

In Wang Bai's hand, the light belonging to the Imaginary Tree gradually condensed, seemingly sensing the thoughts of the person making the wish, and the light grew brighter and brighter.

Shinmen Musashi's heart pounded as he recalled the sacrifice of the monk Takuan, the devastation of the villages along the way, and the deaths of his comrades-in-arms—

A moment later, he suddenly opened his eyes and reached out his hand to Wang Bai.

In an instant, Shinmen Musashi seemed to see a platinum halo radiating brilliant light appear behind Wang Bai, slowly rotating in the sky.

After the light faded, Shinmen Musashi opened his eyes and looked at the scene before him.

The scene before him was so familiar, yet so painful. The familiar bald head and the monk's robes appeared before Shinmen Musashi once again.

"Stinky monk—"

'

Shinmen Musashi blurted it out unconsciously.

Upon hearing Shinmen Musashi's voice, the monk Takuan turned around, saw him, and immediately scolded anxiously, "Didn't I just tell you to leave?! Why are you still here! This isn't the time for you to act recklessly!"
