Invincible in the world, starting with the ghost curse

Time flew by, and it had been almost a week since Kamiya Seiichi arrived at Demon Slayer Corps headquarters. He spent most of that time training and adapting to his surging strength. In his spare time, he would exchange breathing techniques and swordsmanship with Kanroji and the swordsmen who had returned to headquarters.

Some time ago, Seiichi Kamiya took some time to visit the three little ones who were recuperating from their injuries. Inosuke recovered the best and was already able to jump around. Zenitsu was not seriously injured and was almost well, but he still had a sullen face, pretending to be injured, trying to avoid going on missions.

Tanjiro was still wrapped in a bunch of bandages. He was the most seriously injured. Not only did he lose too much blood, but he also exploded with injuries. It would take some time for him to recover.

The three little ones were overjoyed at Kamiya Seiichi's arrival. Zenitsu even boasted to the three little ones from the Butterfly House—Qing, Xiaocheng, and Xiaoho—how great he was. Inosuke, on the other hand, was clamoring to have a duel with Kamiya Seiichi.

Seiichi Kamiya beat him up without any mercy, and Inosuke was happy to get another half week of time to recover from his injury.

The three little ones told Kamiya that Shinobu Kocho would be back soon, probably in the next few days.

Kamiya Seiichi has been coveting Shinobu Kocho for a long time. Of course, he is not referring to her as a person, but the poison techniques she mastered. If possible, he still hopes to learn more about her skills to prevent himself from encountering such enemies and being tricked and sacked when traveling through the heavens.

Today was almost the time. Kamiya Seiichi shaded his eyes with his hands. The blue sky was dotted with a few white clouds. It was a sunny day today.

Pack up your things, grab your katana and head to the Butterfly House.

"Lord Yang Zhu, good afternoon!"

"Master Yang Zhu, thank you for your guidance yesterday!"

"Master Yangzhu..."

Some members of the Demon Slayer Corps that he met on the way greeted Kamiya Seiichi one after another. In the process of communicating with these swordsmen, he would inevitably give them some advice. As time went by, the Demon Slayer Corps swordsmen at the headquarters knew about this new pillar in advance and showed more respect for him.

Seiichi Kamiya also nodded in greeting.

It wasn't long before they arrived at the Butterfly House. Before they even opened the door, they could hear Inosuke's noises and the sounds of Tanjiro's rehabilitation training.

When he looked up at the door, a purple-haired girl was standing on the bamboo wall, staring at him blankly.

Pink-purple eyes with diamond-shaped highlights, cherry pink lips, bangs, a side ponytail, and an emerald green butterfly hairpin with a pink edge.

Kanao Kurika, if Kamiya Seiichi remembers correctly, should be the adopted daughter of Shinobu Kocho. In addition, she has another very interesting identity: Tanjiro's future wife. The latter is more interesting to Kamiya Seiichi than the former.

Tanjiro, would you like a wife if I could give her to you? He thought with a malicious look.

There was a gentle knock on the door, and the one who opened it was a girl with black hair, blue eyes, and twintails wearing a blue butterfly hair accessory, Kanzaki Aoi.

"Mo~ Kanao, since you are here, please open the door."

He ran and complained as he opened the door. Outside the door was a handsome swordsman with blue eyes, long hair tied up and draped over his back, wearing loose-fitting woven clothes, and a katana that looked nothing like the Nichirin sword hung on his right hand.

"Who are you?" Kanzaki Aoi was a little confused.

"Qingyi, are you here to see us?" Tanjiro, who was still being stared at by Xiao Cheng and had to do rehabilitation exercises, shouted loudly.

"Yes, is this Lord Yangzhu? Excuse my rudeness, please come in!" Kanzaki Aoi quickly opened the door and made way.

Kamiya Seiichi smiled and nodded, glanced around, said hello to Tanjiro, and prepared to follow Kanzaki Aoi into the house. Inosuke was still doing push-ups, and Kanao was still in a daze.

Did you hit Inosuke too hard last time? He might have become autistic. What Kamiya Seiichi didn't know was that Inosuke was actually secretly glancing at him, and when he saw that he didn't react to him, he instantly took off.

"There's a flaw! The pigs are charging forward!"

Before reaching the door, Kamiya Seiichi smiled evilly, turned around and stretched out his hand, directly holding down Inosuke who was rushing towards him. Inosuke shuddered when he saw Kamiya Seiichi's smile, and cold sweat flowed down his pig head.

"Tanjiro, let me give you some weight!"

After saying that, he twisted his legs, and the air turned into a vortex. Inosuke was thrown out directly in the direction of Tanjiro.

Tanjiro looked at Inosuke falling from the sky, his face changed drastically, and he dodged with a roll. Inosuke fell straight to the ground.

Good brother, Kamiya Seiichi gave him a thumbs up and turned around and went into the house.

In a warm and elegant room, Shinobu Kocho sat upright on a coffee table, her hands moving smoothly and gracefully, and the faint fragrance of tea filled the room.

"Ah, we have a distinguished guest today."

Stopping what she was doing, Shinobu Kocho looked up and looked at Kamiya Seiichi curiously. This man would be one of her most trustworthy companions in the future.

Every pillar is a comrade who can live and die together.

Kamiya Seiichi was also sizing up the dignified woman before him. Shinobu Kocho had black hair, her bangs a distinctive purple at the ends, and a butterfly hairpiece tied her hair back. Her purple eyes were deep and bright, and she wore a haori patterned with butterfly wings.

In Kamiya Seiichi's memory, Kocho Shinobu's popularity has always been high in her previous life. In addition to her beautiful appearance, her seemingly gentle personality and the dark side hidden underneath are also very impressive.

"I learned that the Insect Pillar had returned to headquarters early, and since we need to meet for the upcoming meeting, I thought it would be best to do so today, so I wanted to visit him in advance. I also have a selfish motive; I want to exchange swordsmanship experiences with each of the Pillars."

Kamiya Seiichi sat straight across from her. Shinobu Kocho's fair, creamy hands lifted the teapot and poured a cup of tea for Kamiya Seiichi.

"If I can help you, I'd be happy to. But I might disappoint you because I'm not strong enough, and my swordsmanship isn't as good as the average Pillar."

Kamiya Qingyi did not show any surprise, but stroked the teacup thoughtfully.

"I see. I've heard that the Insect Pillar possesses profound knowledge of pharmacy and poisons, which more than makes up for his lack of strength. To be honest, I'm also very interested in knowledge of pharmacy. I wonder if we could exchange ideas."

Now it was Shinobu Kocho's turn to be surprised. The knowledge about potions was very dull and boring, and as far as she knew, the pillar in front of her was a powerful kendo master who was good at head-on confrontation.

“Of course.”

But since the other party has an idea and can help others, she naturally has no objection.

"Then I'll bother you starting tomorrow."

After that, the two chatted with each other a lot, about what they saw and heard outside and Kamiya Seiichi's past, etc.

"It's getting late. I'll come back tomorrow." After saying goodbye to Shinobu Kocho, Kamiya Seiichi prepared to leave. As he passed by the ward, he glanced at Tanjiro. The kid was still secretly practicing.

Without disturbing him, Kamiya Seiichi quietly left the Butterfly House.
