Chapter 130 Raising Children Isn't Easy

Kaigaku, who was initially defiant and rebellious, gradually compromised, looking dejectedly at Iwakatsu playing chess with an elegant air.

"How's your training going?"

Kaigaku truly admired Iwakatsu. After a brief discussion with the female ghost playing the biwa, Iwakatsu devised a changeable trap trial route for him, which he had to complete within a set time.

"I did it."

After seven days of death training, Kaiyue felt like he had been reborn; in fact, he now has a stress response whenever he hears the sound of the pipa.

"Very... impressive."

Yan Sheng stood up, placed his hand on the other's messy black hair and ruffled it, his six golden eyes curving slightly.

"It's not that difficult."

Kaigaku's face flushed red. Kokushibo was the first elder to pat his head, which made him a little uncomfortable.

"Then I... there's nothing... I can... help you with."

Iwakatsu had originally planned to go to Tokyo, but postponed it due to Kaigaku.

The opponent has been developed very well, and he doesn't know Thunder Breathing either, so he can only ask Nakime to create a training ground tailored to him to break through his limits.

To be honest, Nakime seemed quite interested in this, even more so than Iwakatsu in arranging the trap locations and changing the spots.

It seems that staying in the Infinite City is indeed quite boring. As the boss's close attendant, I am on call 24 hours a day.

What a pitiful working person. Luckily, I'm the vice president. Yan Sheng felt sorry for the other person for a second.

Besides that, he also corrected the opponent's mistakes in swinging the sword. In terms of moves, although he could detect the problems, he couldn't explain them clearly.

He had already planned it all out. Once the other person successfully completed the challenge, he would take him to Momoyama. Only a user of Thunder Breathing could understand how to teach him.

"Huh? Going to Momoyama? Why!"

After washing up, Kaigaku heard the bad news and was extremely unhappy.

"Let your master... teach you."

"You're even better than him!"

Kaigaku didn't want to go back. In his eyes, that guy only adopted another good-for-nothing because he couldn't learn the First Form.

“Only those who know that…breathing…method…know how…to…teach it.” Iwakatsu looked at Kaigaku’s sulking appearance as if he were a rebellious teenager. “Besides, you…also…treat him…as your master.”

Indeed, in any case, Kaigaku greatly admires and aspires to inherit the mantle of Kuwashima Jigoro.

"I'm not going."

Having spent time with Kaigaku and Iwakatsu, he had figured out each other's personalities, and he started to throw a tantrum.

Unfortunately, Yan Sheng ignored him this time, only giving him a faint glance.

"You have no choice."

Kaigaku's face darkened instantly, and Iwakatsu sighed, feeling that raising a child was like raising an ancestor.

Yoriichi and Yuichiro were like that, and so was Kaigaku.

"Try it, you won't lose out."

Besides training his opponent, Yan Sheng also took the time to instill new ideas in him and showed him around.

In Iwakatsu’s view, a person needs to broaden their horizons to be more receptive to new things, and going to different places to experience them is the choice Iwakatsu makes.

If it weren't for the short time, Iwakatsu wouldn't have just taken him to see the place; he would have stayed for a while (like Ichiro Toki).

Kaigaku has changed a lot too; perhaps it's because he's learned more that he's different now. He felt Iwakatsu pat his head before giving a muffled "hmm."

It's not close to Momoyama, so we need to take a bus to that area. There's only a train from a neighboring town. Iwakatsu entrusted the important task of getting there to Kaigaku.

Why not teleport?

Kaigaku found it a bit strange. They always traveled to different locations by teleportation, and he had almost forgotten about cars. Suddenly being asked to ride in a car gave him the feeling that his family had gone bankrupt.

"The adults will find out."

After Iwakatsu finished speaking, Kaigaku shut up. He was Upper Moon One, and the only demon he could call "master" was Kibutsuji Muzan.

Iwakatsu wasn't sure whether train tickets needed to be booked in advance, so after thinking it over, he decided to randomly go to one of Boss Xie's properties to sort it out.

Anyway, I've spent a lot of money back and forth during this period, so the other party won't specifically investigate this matter.

"Lord Kokushibo, the train probably doesn't check tickets at night, right?"

Kaigaku looked at Iwakatsu and asked pointedly, "I've ridden this before when I was on a mission, but I've never heard of tickets being checked at night."

Oh, he forgot.

Yan Sheng paused for a moment. This was indeed a problem. He had high-speed rail tickets for the evening in modern times, which made him forget to check if they were available in this era.

"Then let's not go."

Kaigaku suggested that he could understand Iwakatsu's thoughts, but if possible, he would need to think about it for a while, since he hadn't been back much since becoming a member of the Demon Slayer Corps.

The last time I saw that little old man was a year ago, and I just said hello.

Yan Sheng narrowed his eyes slightly. He knew all of this guy's little schemes, but unfortunately, he was the kind of person who liked to go against him.

"I'll arrange for someone to take you there. You can carry it and I'll go with you."

As Yan Sheng spoke, he took out a leather suitcase that he always used to store clothes and other things. He took out the contents and looked at the empty space, thinking for a moment.

"ah?"

Under Kaigaku's questioning gaze, Iwakatsu shrank on the box and tried to lie down inside.

What is that?

Kaigaku stared in shock at Iwakatsu, who was trying to pry the other half of the box shut. He opened his mouth but couldn't utter a single word.

"Look, what... help?"

Yan Sheng looked up and saw the way Kaigaku was looking at the magical creature. He felt a little embarrassed. It was also his first time trying to shrink, and he didn't know what it would look like.

"good……"

Looking at the child lying down, Kaigaku realized that if he hadn't known that the other person was Iwakatsu, he really wouldn't have been able to make that connection.

He went up and closed the other side, then fastened the box and tried to lift it, unable to resist weighing it in his hand.

"Don't...shake."

Yan Sheng's muffled voice came through, carrying the soft, childlike tone of a child, indicating that it wasn't just his body that was changing.

Unlike Muzan Kibutsuji, Iwakatsu rarely attempted this kind of mimicry and often failed to control it well. For example, this time, he actually transformed into his childhood self, rather than simply shrinking his body.

Kaigaku stopped what he was doing, feeling a bit of novelty; it was the first time he'd ever lifted a demon. It was very light, probably only about 20 kilograms, not even as heavy as the stone he'd carried during his first training session.

"Slap slap—".

While Kaigaku was lost in thought, he heard a thumping sound coming from the suitcase. He picked it up and was somewhat impressed by its quality; it was indeed something from a wealthy family.

"Open…"

Iwakatsu's voice came from inside, which aroused Kaigaku's mischievousness, and he shook it a few more times.

"Wait a minute, Lord Kokushibo, let me find where the buckle is."

"..."

After being tormented for more than ten minutes, Yan Sheng finally came out. He looked at Kaigaku with an unfriendly expression, his big red eyes narrowed slightly.

"puff--."

Kaigaku couldn't help it, mainly because Kokushi's appearance was too funny; he never expected that Kokushi would look so cute as a child.

"Before catching the train... go again... training, long-distance running, twenty times... that's fine."

"???"

Yan Sheng said coldly, he thought this guy was just too idle and it would be better to find him something to do.
