Nobita, quickly use your invincible treasure bag to think of a solution!

"Wait a minute, if the smell next door comes from Mr. Yiyong and Senior Sister Xuntu, then what is the smell in the corridor...?"

Tanjiro rubbed his nose, re-analyzed the smell around him, and then...

"I kill you!"

Bang!

The door of the next room was violently slammed open. Tanjiro and Zenitsu looked in the direction of the sound and saw Nobita and Miss Shinobu rushing out of the next room at the same time.

Nobita is here, his clothes are in disarray, except for a pair of shorts.

Miss Shinobu was on top, with her pink feet stepping on Nobita's chest, holding a cloth shoe in both hands above her head, and a sharp blade flashing at the front of the shoe.

After the two men rushed out of the room, they rolled on the ground. One of them stabbed with a knife, and the other dodged in panic. The entire corridor turned into a battlefield.

Zenitsu and Tanjiro carefully stuck to the wall of the corridor, watching with lingering fear the two people rolling past them.

"Hey, Tanjiro, although Miss Shinobu is wearing clothes, those ropes should be the tortoise shell ropes used in the brothels, right?" Zenitsu recalled the scene he had just seen and asked Tanjiro uncertainly.

"It's not tying, it's binding. It looks like Nobita has humiliated Miss Shinobu again." Tanjiro corrected Zenitsu.

While the two were chatting, they found that many women had just walked out of Nobita's room, Miss Mitsuri, Miss Kanae, Miss Spider... Each of them had messy hair and they were changing clothes. It could be seen that they were very anxious and were eager to stop Shinobu Kocho.

Seeing that everyone else had exchanged clothes, while Miss Shinobu was still wearing her original clothes with an extra set of ropes on her body... Tanjiro and Zenitsu combined their past experiences in the yujo house and suddenly thought of a possibility.

Did Nobita tie Miss Shinobu up in such a shameful manner last night and hang her from the beam all night?

Chapter 438: Zhu Guidance Training

Under the gazes of Iguro Obanai and Shinobu Kocho that seemed to be trying to kill someone, Nobita finished his breakfast and ran to the courtyard to bask in the sun while holding the shrunken Nezuko.

Nobita sat on the swing and Nezuko sat on Nobita's legs. The two of them swung leisurely on the swing, basking in the sunshine above their heads, and they enjoyed the rare late autumn time.

Meow~~~

A slightly timid cat's cry came from the cherry tree next to the swing, and a calico cat carrying a small wooden box jumped down from the tree and landed in Nezuko's arms.

"Meow meow." Nezuko, with the heart of a child, held up Chachamaru and imitated a cat's meow, trying to talk to Chachamaru.

However, Nezuko is not proficient in cat language, and her cat meows are meaningless. It is even better to talk directly to Chachamaru in human language. At least Chachamaru can understand human words.

Nobita asked Chachamaru, "Since you're here, that means Tamayo's mother is here too. Did she and Yushiro agree to join the Demon Slayer Corps?"

"Meow."

Chachamaru nodded.

"Okay, let's meet in the basement of the Butterfly House. There are ready-made research equipment there."

Nobita nodded and agreed to Chachamaru's invitation from Tamayo.

The news that evil spirits are not afraid of sunlight also reached Tamayo's ears, and she was also very interested in the changes in the bodies of Nezuko and other demons.

After relaying the words, Chachamaru was about to turn around and leave, but was stopped by Nobita.

"Wait, don't leave yet. I'll give you an injection. I'll have to ask you to protect Tamayo's mother in the future."

Nobita grabbed the scruff of Chachamaru's neck and pressed it into his arms.

Amid Chachamaru's puzzled meows, Nobita took out a tube of ghost transformation potion from his treasured collection and injected it into Chachamaru from behind his neck.

"Meow!!!"

Chachamaru let out a shrill cry. Nezuko felt sorry for Chachamaru and held him in her arms, trying to calm the cat down.

The potion that Nobita gave to Chachamaru is a potion that has fixed blood demon magic.

The potions that Nobita injected into Kyojuro and the others in the past were all ordinary demon-transforming potions, which only turned people into demons. As for whether one could obtain blood demon arts, it depended on one's personal qualifications.

The reason why the potion that Nobita injected into Chachamaru now is called a rare potion is because it contains two fixed blood demon arts, one is the body-transformation type blood demon art, and the other is the spell-type blood demon art.

There is no need to explain the blood demon art of body transformation. Chachawan can do it, such as limb expansion and body deformation. Turning from a cat into a saber-toothed tiger is just a matter of thought.

The magical blood vampire magic is very powerful. Chachawan can release sunlight, but this sunlight can only appear on Chachawan's body surface. Although it can make Chachawan glow like the sun, the distance that the sunlight can be transmitted from its body is very limited, only three centimeters from the body surface.

The second blood demon technique has no effect on humans, but when facing evil spirits, the effect will be very obvious. Chachawan is like a cat-shaped red knife, which is simply a weapon for killing demons.

"Meow?"

Cha Cha Wan stood on his hind legs and kept feeling around with his body with his front paws, but after searching for a long time, he didn't find that he had grown an extra claw or a head.

"Okay, stop touching me, and go back quickly. You'll be my secret weapon when I fight Muzan from now on." Nobita rubbed Chachamaru's head, urging him to go back to the group chat.

"Meow? Meow meow meow?" When Chachamaru heard that he was going to beat Muzan, he meowed like a cat, his eyes full of confusion.

However, Nobita did not explain anything to Chachamaru, but just urged it to leave quickly, while he continued to swing on the swing holding Nezuko.

This shaking lasted for a month, until December.

……

Fujisaka Mountain, which was once used as the final trial, has now had all the evil demons in the mountain exorcised and killed. The former examination hall has now become a dedicated training ground for the Demon Slayer Corps.

Today, the middle and high-level combat forces of the Demon Slayer Corps have been fully gathered in Fujisaki Mountain, and only swordsmen of level G and below are responsible for patrolling outside.

The war is imminent, low-level combat power is no longer of any use, and the evil spirits begin to change their strategy. They either do not take action, or if they do, they massacre the entire village and street, leaving no one alive.

In a battle of this level, the only thing a low-level swordsman can do is to gather intelligence, while the task of eliminating the evil spirits is still left to the pillars.

At the foot of Mt. Fujishiki, the class of Yuichiro has begun. The swordsman with the legendary initial breathing method will give personal instruction to ensure that every swordsman can greatly improve his or her combat power, gain a deeper understanding of the breathing method they have mastered, and greatly improve their combat power. In addition, teacher Yuichiro will thoughtfully complete some incomplete breathing methods.

There are a large number of swordsmen participating in this course. In addition to healthy swordsmen, there are also a large number of disabled swordsmen participating. They all come to learn breathing techniques and intend to contribute to the final battle.

The conditions proposed by Nobita were spread out!

As long as you participate in killing the Upper Moons and the Demon King, you can resurrect your loved ones, lovers and family. What a tempting condition!

As mentioned before, of the people who can join the Demon Slayer Corps, only a small number do so for money. Most of them join the Corps because they have a grudge against evil demons, or their family has been wiped out by evil demons, or their loved ones have been killed by evil demons. That is why they join the Corps to fight for life and death with the demons.

The fate of these people who bear deep hatred has long been entangled with evil spirits. Unless they die in battle or become disabled and can no longer pick up the Nichirin Sword, they will continue to fight.

Unfortunately, not everyone has the talent to become a pillar-level existence, and not everyone is like Tanjiro and his companions, who can survive unscathed even when encountering evil demons of the level of the Twelve Kizuki. There are always swordsmen who become disabled because of fighting and retire and leave the Demon Slayer Corps.

But fortunately, these disabled swordsmen have caught up with good times. The demonization potion prepared by the Insect Pillar himself can help them grow their limbs back and make them healthy people. So now even those retired swordsmen have to pick up the Sun Blade again.

Not to mention that they can get a chance to resurrect their family members by fighting, the potion that can grow back their limbs is enough to get them to return to the team.

Therefore, there is a constant stream of swordsmen coming to attend Teacher Yuichiro's class.

Because only by mastering their own breathing methods can they proceed to the second item, which is basic physical training, and have the opportunity to get injected with ghost potion to make their bodies healthy.

Halfway up the mountain, a group of swordsmen, with their upper bodies bare, revealing their muscular bodies, were doing extremely intense physical training. A group of people were hanging sandbags weighing dozens of kilograms, maintaining normal breathing, running along the mountain road to the top of the mountain, and after five laps back and forth, they did push-ups, sit-ups, frog jumps and other training.

At dusk, Shinobu Kocho would line up the tired swordsmen to be injected with demonization potion, and then have them start a new round of training, using ordinary swords for melee training, with every sword piercing the flesh and stabbing the body, and the fighting would continue until dawn. Only this kind of high-intensity training could allow the swordsmen to quickly become familiar with their breathing methods and increase their practical experience.

As long as a swordsman can rely on the human body and complete a full set of physical training during the day without changing his expression, he will be considered to have passed the test and can enter the next stage of training.

Unfortunately, only 60% of people can complete this most basic training.

The third stage of training is flexibility training from Mitsuri. A group of swordsmen have to wear tight ballet costumes and dance with Mitsuri. At the same time, they will do exercises such as stretching and opening the hips to enhance the flexibility of the body.

The tasks at this stage are the simplest. As long as you can do the splits and move both legs to your neck, you will pass.

For people at this stage, the probability of passing the test is 80%.

The fourth stage of training is Iguro Obanai's sword posture correction training.

The training for this level requires the swordsmen to accurately draw their swords through the gaps in the mechanisms set up in Iguro Xiaoba to block the attacks of the puppets in front of them. If the sword-drawing posture is incorrect and the blade touches the mechanism, the electric current connected to the mechanism will shock the swordsmen and cause them to become incontinent.

Thanks to Shinobu Kocho's demonization potion, as long as these swordsmen are not exposed to sunlight, the effect of the potion will last for a long time. Ordinary weapons can't kill them at all, and neither can strong electric currents, so they can train at will.

The effect of this training is very significant, but the price is that the venue in the small banana tree smells bad and the smell of urine is too strong.

The training at Iguro Obanai is not difficult, it's just that the process is a bit painful. However, after such training, the effect is still amazing, and the pass rate is 100%.

The training instructors for the fifth stage are Muichiro and Kanae. The training of these two people can be regarded as the preparatory training for the transparent world. One of them summons mist and controls shadows to attack swordsmen, while the other controls hair to launch sneak attacks and tie up swordsmen.

Allow swordsmen to train through senses other than vision, such as smell, hearing, and touch.

The eyes can be deceiving, and human vision may not be able to keep up with the speed of evil spirits, but other senses are different. The sense of smell can smell the scent of evil spirits, the sense of hearing can hear the heartbeat of evil spirits, and the sense of touch can detect the traces of evil spirits with the help of the flow of air. They are all clearer than visual perception.

From this stage on, Tanjiro and his companions have left the other swordsmen behind and are far ahead.

This is their respective area of expertise.

In the first few training sessions, the gap between everyone was not too big. Everyone was good at different things. For example, in basic physical training, some swordsmen were young and strong, with fully developed bodies, so they trained faster and left behind the protagonists such as Tanjiro.

Mitsuri's flexibility training later was extremely easy for someone like Inosuke, whose body was so flexible that he was almost boneless, so Inosuke only trained for half a day and successfully advanced to the next stage of training.

Later in Iguro Obane's electrotherapy training, because Zenitsu often had to make quick, accurate and ruthless strikes, he was the first to break through and enter the next stage.

When it came to Muichiro and Kanae, Tanjiro was able to quickly dodge the attacks of the two pillars by relying on his sense of smell and the transparent world he had mastered in advance.

Zenitsu can rely on his powerful hearing and extreme speed to take the lead in launching a counterattack against Muichiro and his men.

Inosuke can rely on the flow of air to detect the target's murderous intent in advance and counterattack in time.

So the three of them first entered the sixth stage of training, which was the blood demon magic attack training from Kyojuro.

The sixth stage of training emphasizes the ability to adapt to the advanced combat power of the evil ghosts. The swordsmen must adapt to the combat rhythm of the first level of the Twelve Demon Moons.

Considering that the gap between the Twelve Kizuki and ordinary swordsmen is like heaven and earth, the outcome of a fight between the two is basically decided by one move. Therefore, what Kyojuro wants to train is the swordsmen's ability to adapt to various blood demon arts, so that at least when attacked by the Twelve Kizuki, they can launch an effective counterattack and create opportunities for others.

This stage of training was very tough for Tanjiro and his companions. They were bombarded with all kinds of blood demon arts. One second they dodged a big fireball, and the next second their eyes blurred and a split fireball exploded in front of them. There were water balls, electric balls, conductive water balls, and many other blood demon arts in different forms and shapes that tortured the three of them terribly.

It took the three of them a month to barely pass the test, relying on their own perseverance to force themselves to absorb the blood demon technique activated by Kyojuro and effectively attack Kyojuro once.

The seventh stage of training is the extreme strength training that is in charge of Gyomei Hirame. Again, there are only three swordsmen including Tanjiro who can reach this stage. Most of the swordsmen are stopped in the fifth stage of training.

This training was also not difficult for Tanjiro and the other two. A week was enough for them to carry the huge rocks back and forth on the mountain.

Inosuke and Zenitsu practiced the martial arts passed down to them by Nobita, one trained their body and the other trained their energy. With their inner strength as support, they could easily tackle thousand-pound rocks.

Tanjiro has had ghost hands attached to his body, his physique has been infiltrated by ghost cells, and he has also eaten blue red spider lilies. His body is half ghost, so it is not difficult for him to carry stones.

The battle against the Wind Pillar in the eighth stage was a little troublesome for the three of them, but only a little troublesome. In terms of physique, they were far superior to the Wind Pillar. In terms of breathing method, the Sun Breathing was much stronger than the Wind Breathing. The only thing was that in terms of combat experience, the three of them had too little experience. However, after being taught by the Wind Pillar, they were able to get the hang of it quickly.

So a week later, Tanjiro and others began to follow Yoshiichi Tsugakuni to learn how to open the patterns, the red sword, and the transparent world.

Coincidentally, Tanjiro can also perform all of Yoriichirō's unique skills.

Tanjiro inherited the markings from Tanjuro, and can open the Red Blade through Nezuko's explosive blood. He also once opened a transparent world on the Infinite Train. After being taught by Yoriichi, he mastered the meaning of the "circle" in the Sun Breathing, and Tanjiro ended his training directly.

As for Zenitsu and Inosuke, neither of them could open their markings, but they were able to quickly master the red sword and the transparent world by taking shortcuts.

So the three protagonists successfully completed the training under the guidance of the pillars and became the first three to graduate.

At this time, after a round of training, winter has gone, spring has come, and it is March.

According to the intelligence records of the Demon Slayer Corps sent by Yagu, the evil demons that have been silent for a long time have become active again, and even swordsmen have disappeared.

The war is about to break out!

Chapter 439 Since we want to pursue excitement

The sky was foggy, and soon it began to rain. Raindrops connected into lines and dripped onto the roof of the Butterfly House, sliding down the tiles of the roof to form a water curtain that hung on the outside of the corridor in front of the bedroom, dividing the courtyard and the bedroom into two worlds.

In the bedroom, a woman was kneeling. She had long hair that was half green and half black and fell below her shoulders. She looked pretty and was wearing a loose white kimono. She was sitting quietly in the room, staring at the courtyard outside in a daze.

"Well!"

Suddenly, the woman felt inexplicably nauseous. She stood up, covering her mouth, and ran quickly towards the bathroom on her bare feet on the brown floor.

vomit! ! !

Not long after, the sound of retching was heard from the bathroom.

After a while, the sounds of flushing and the faucet turning on were heard from the bathroom. As the woman raised her face to the mirror above the sink, she saw Yushiro's face in the mirror.

In other words, Yu Shi Niang!

Yu Shi Niang looked at her bloodshot eyes and haggard face, reached out to feel the fetal movement in her belly, her eyes full of confusion.

Why did I become like this?

Yu Shi Niang’s memory was pulled back to a month and a half ago.

That day was two months after Lord Tamayo and she came to the Butterfly House. At that time, she was still him!

……

In the basement of the Butterfly House, which used to be the research laboratory of Shinobu Kocho, there is a long table in the bright room, on which are placed equipment such as test tubes, beakers, and alcohol lamps.

Standing in front of the table was a woman with her hair tied up and a mask on her face, so her real appearance could not be seen. The woman was wearing a white coat and was concentrating on the experiment.
