With a reputation of 70,000, one leader travels across countless worlds with his adventure team.

Having learned about the Mugen Train, Flame Pillar Kyojuro Rengoku arrived at the train maintenance station under the guise of delivering bento boxes. Just as he was about to inquire about the Mugen Train, Ripper, unable to bear the smell of the bento boxes, grabbed a maintenance worker and rushed out.

Ripper had been torturing people for a while in the villages near the train repair station. The sudden intrusion of Flame Pillar annoyed him greatly. The smell of the bento that Kyojuro brought from the station disgusted Ripper, and he shouted that he would go to the station to kill the person who bought the bento.

Seeing the Ripper escape using the Super Speed ​​Blood Demon Art, Kyojuro assigned the injured to the follow-up team members, went outside the repair station, took a deep breath and circulated the Yi Jin Jing, and caught up with the Ripper at the station in just a few seconds.

The Ripper, who had just arrived at the station and found the bento box containing the grandfather and grandson, was still spouting nonsense like a talkative villain, arrogantly not caring that Kyojuro would catch up.

Grandma held the bento box to distract the Ripper, hoping to get her granddaughter Xiaofu to run away quickly. The Ripper, who had been hit on the head by the bento box, was thinking of strangling the old woman first and then chasing after Xiaofu to torture and play with her.

Kyojuro, who was chasing behind, didn't say much. He simply beheaded the Ripper with a single stroke, sending him flying. The Ripper's head, flying through the air, murmured in disbelief:

"How could it be so fast..."

Flame Pillar Kyojuro Rengoku rescued a grandmother and her granddaughter Fuku, who were selling bento boxes, at the train station. The grandmother looked at Kyojuro's tall and familiar back, and the familiar way he sheathed his sword and wore his haori reminded her of 20 years ago, with the same back and the same sword-sheathing action.

Tears welled in Grandma's eyes as she spoke emotionally:

"Just like 20 years ago, you saved me again... saved me twice... sob..."

The adorable granddaughter knelt down to support her grandmother, and then the grandmother continued:

“I will never forget that face, that cloak, and how you saved me and Xiao Fu’s mother twenty years ago.”

Hearing his grandmother's excited words, Kyojuro turned around and said:

"That must be my father. I inherited his career and take it as my duty to exterminate demons."

Grandma burst into tears upon hearing Kyojuro's words, and her granddaughter, Kofuku, wiped away her tears, puzzled.

"It is my honor to protect you like a father would!"

At this point, the ordinary team members hurriedly arrived at the station. After special training, Flame Pillar was much stronger than before, and this time he arrived at the station even faster than in the original series.

After learning that the Mugen Train would resume operation the next day, Kyojuro decided to travel on the train himself and conduct inspections on board.

 …

The next afternoon, the three children successfully encountered Enju before boarding the train. They saw that Enju was carrying two large bags of bento boxes. Kyojuro had sold a large number of the bento boxes that the grandfather and grandson had brought at the station.

Since they had met during the previous special training, the four of them chatted and laughed as they got into the car. And what about our Bai Ze and the four women?

Because Bai Ze didn't know the station's location, he went to the wrong place. After asking about the location of the Infinite Train at the wrong station, he simply summoned Viserion after sunset and flew directly along the railway line. He figured he would know the location when he saw the glowing, moving firefly caterpillars on the ground.

After getting on the train, Kyojuro ate his bento box while shouting "Five ants!" He ate about ten bento boxes in no time, making Inosuke, the pig, drool. In the end, he couldn't resist and grabbed a bento box to start eating heartily.

"Five ants!"

It was so delicious that even the piglet exclaimed. Looking at the piglet's expression, Kyojuro smiled with a reassuring smile.

Zenitsu felt extremely embarrassed sitting next to Inosuke and kept covering his face, not wanting to see how Inosuke ate.

After getting on the train, Tanjiro smelled a faint demonic scent. After watching Kyojuro finish his bento, Tanjiro described the smell he had detected.

"Brother Kyojuro, the whole carriage smells of ghosts, and there are several different kinds of ghosts."

Just then, the ticket inspector came to check the tickets, and as soon as the ticket check was completed, the lights inside the train began to flicker erratically.

Both Kyojuro and Tanjiro sensed something was wrong. Kyojuro, sensing something, stood up and looked at the train door on one side.

In the instant the lights went out, a burly ghost with a dark gray body, horns on its head, and several faces suddenly appeared on one side of the carriage, causing the passengers on both sides to tremble with fear at the sudden appearance of the ghost.

Just as the demon roared and prepared to stand up, Kyojuro drew his sword and instantly appeared before it, slashing diagonally across the demon's reclining neck. Only then did everyone hear:

"Flame Breathing, First Form: Shiranui!"

The three children were stunned. Tanjiro instinctively shouted, "Haaah! So fast! He severed the demon's head with a single stroke. That's amazing!"

The passengers in their seats then realized what was happening and rushed towards the other door where the train conductor was located.

At this moment, Tanjiro smelled the scent in the air, looked up at Kyojuro, Zenitsu, and Inosuke, and said:

"The smell of ghosts is still there, and there's more than one!"

Kyojuro also looked at the carriage behind him and in front of him, and said:

"Is there one more? Follow me!"

Inside the carriage ahead, a ghost with long arms and legs was clinging to a passenger, its four eyes darting around, and its drooling mouth open, ready to bite.

Kyojuro and his three companions entered the carriage. At that moment, Inosuke drew his twin swords and shouted:

"Strike first is the strongest!"

He charged straight at the long-armed, long-legged ghost. Just as Piggy swung his twin blades, two more arms emerged from the ghost's belly and struck at Piggy. Piggy pressed down with his twin blades, striking the ghost's hands, and then flipped over the ghost's head.

At that moment, Kyojuro rushed forward and carried the passenger out from under the demon's body. Tanjiro, sword in hand, passed by Kyojuro and charged forward.

The long-armed demon stretched out its two long arms to grab Tanjiro. Tanjiro jumped up to dodge, and just as his body was flying over the demon's head, Tanjiro took a deep breath.

"Hinokami Kagura: Azure Heaven!"

Tanjiro unleashed a circular slash directly above the demon's head, splitting it in two at the chest. Inosuke, who had just been thrown out, then leaped up, stepping on the demon's lower body, and slashed directly at the demon's shoulders with his twin swords.

The demon roared and flew towards Kyojuro and Zenitsu. When it landed, it had turned into a plaster bust in the art room, with only half of its chest and head remaining.

The demon roared, its four eyes throbbing with pain and starting to look at each other indiscriminately. At that moment, Kyojuro slashed the demon's neck with his sword, silencing it. In no time, the demon, now in pieces, turned to ashes and disappeared before everyone's eyes.

Kyojuro sheathed his sword and looked at Tanjiro and the other two. He didn't speak to Zenitsu, but instead looked at Tanjiro and Inosuke and said:

"The special training has been very effective, and you have all become very strong swordsmen. However, when you encounter a demon, you must not panic. You must always be aware of whether there are any civilians around the demon and make sure the safety of the people around you is guaranteed!"

Tanjiro was so excited he was almost in tears, and said:

"That's incredible! Brother Kyojuro, your swordsmanship is amazing! You beheaded that demon in one strike!"

"Hahaha...hahaha, you guys are great too, you have excellent teamwork and your attacks are very efficient, awesome!"

Most of the carriage was destroyed, and the passengers in this carriage ran to the carriages behind. Kyojuro and the three little ones returned to their own carriages and began to rest. Just as they were falling asleep, Lower Moon One, Enmu, dragged everyone into a dream.

Inside the carriage were several seriously ill individuals who had voluntarily come to live in a dream of happiness. Nightmare had arranged for them to enter the dreams of Kyojuro and the three little ones, intending to destroy their "spiritual cores," turn them into cripples, and then kill them for his amusement.

However, to Enmu's surprise, Tanjiro was carrying a demon with him. Nezuko, sensing the abnormality, woke up and used her Blood Demon Art to revive her brother Tanjiro.

Tanjiro then woke up Inosuke and Kyojuro, while Zenitsu, who was asleep, sensed Nezuko's presence and actually came to her side while asleep.

Suddenly, the entire carriage underwent a strange change, with dark red lumps of flesh filling the train.

Having long since merged himself with the train, Lower Moon One: Nightmare was not afraid of the few swordsmen causing trouble inside his "body." As long as they wanted the more than two hundred passengers on the train to survive, they dared not use their skills and could only keep slashing.

Once the others had exhausted their strength, it would be time for him to eat. Thinking of this, Enmu let out a perverted smile. The slashes from Tanjiro and the others struck Enmu's body, but instead brought Enmu a different kind of pleasure.

Bai Ze led the four women along the railway in the sky, but after a while, a thick fog covered the surroundings, so Bai Ze had to have Viserion descend and proceed slowly.

A moment later, the clanging of a train came from ahead. Bai Ze looked up and saw the faint lights slowly approaching through the thick fog. Bai Ze turned to the four women and said:

"The train is coming, get ready!"

Viserion flew to the top of the train before everyone could see what it looked like: a bizarre, dark red fleshy structure completely surrounded the train. Mengmeng, her little face scrunched up, said:

"Big brother, should we jump on? It feels so uncomfortable on the train."

Looking at the ghostly train, Bai Ze knew that Nightmare's head was inside the engine. A brilliant idea struck him, and he said to the girls:

"I've got an idea. I'll go to my personal space. Please wait a moment."

After speaking, Bai Ze vanished from the dragon's back in an instant.

Upon entering the space, Bai Ze opened his eyes and looked at the luxurious Chinese-style courtyard inside. He walked in and, after only a few steps, heard the clattering of mahjong tiles in the entertainment room on the first floor.

Bai Ze pushed open the door and went in, seeing Daenerys and the other girls sitting around the table, playing mahjong.

Hearing the door open, all the women looked towards the entrance. Seeing Bai Ze enter, they all stood up and came to his side, saying:

"You stinky man, you've only come in to see us a few times in all this time. How long will you stay this time?"

Because Bai Ze adjusted the time inside the space to be half that of the outside world, several months had passed in the Demon Slayer world outside, while only a little over a month had passed inside the space.

Because he had previously trained the Demon Slayer Corps Pillars, and later hunted down the Lower Moons of the Twelve Demon Moons across the map.

Bai Ze has returned to the space three times recently, spending time with the women in the recreation room and letting them eat and drink their fill before returning to his work.

So Daenerys kept asking Bai Ze how long she would be staying this time.

Bai Ze, with a steamed bun in his left hand and his right arm around Wang Yuyan, said with a grin:

"What? Don't you think your husband spends enough time with you? Want to go out with me?"

Wang Yuyan blushed as Bai Ze pinched her cheeks and said:

"You're with Sister Raphael and the others outside, so I won't go out."

Wang Yuyan, who naturally preferred quiet and disliked fighting, was getting restless from Bai Ze's mischievous touch and couldn't stand it any longer. She ran off after speaking, and Tifa stepped in to Bai Ze's right, saying:

"Are there any formidable enemies? I haven't fought in ages and I really want to get into a fight!"

Bai Ze thought that Upper Moon Three Akaza would arrive when the Infinite Train's time limit ended. Akaza was also a master of martial arts, so he lowered his head, savored Tifa's flavor, and said:

"A ghost who's really good at boxing is arriving soon, do you want to go out and have some fun?"

Tifa was very excited when she heard about the martial arts master, and nodded frantically, saying:

"Yes, yes, I want to go, I want to go!"
