Kyoujurou believed Su Chen could definitely learn his Breathing Style. But Su Chen shook his head. "Big Brother Rengoku, you're a very kind person," Su Chen said. "But I am already Lady Shinobu's successor, so I'm afraid I can't."
Hearing this, Kyoujurou's large eyes widened slightly. "Is that so? Then that's truly a shame!" Kyoujurou felt a little disappointed. He thought to himself, "Right, with someone as outstanding as Su Chen, how could Kochou Shinobu let him go?" She must have acted first! But he quickly cheered up again. After all, the Hashira were a team. Su Chen becoming stronger was a good thing for the Demon Slayer Corps, so there was nothing to be sad about.
They put down their swords and chatted for a few more minutes. Su Chen and the Rengoku brothers quickly grew closer. Kyoujurou couldn't help but start sharing some of his recent mission experiences with Su Chen. Su Chen listened carefully.
"Mr. Su Chen, there has been a strange incident recently," Kyoujurou said. Su Chen looked up. "Big Brother, please tell me." "Recently, when I've been on missions, I've noticed that the demons' movements have become more regular. Normally, demons act purely on desire, without any pattern. But lately, they've started acting with purpose, organization, and planning." Kyoujurou looked straight ahead, a hint of confusion in his voice. "I suspect they are looking for something, or someone. In yesterday's mission, I learned a piece of information from a demon with a Blood Demon Art."
Under Su Chen's gaze, Kyoujurou said, "They are looking for a black-clothed, masked person." Su Chen was stunned when he heard this.
Kyoujurou continued, "I think this person is the same one Kochou reported last time. Now he has been targeted by the demons." Su Chen suddenly asked, "Is that person not a member of the Demon Slayer Corps?" Hearing this, Kyoujurou shook his head. "No, we don't know who he is either. At the time, the Master asked Kochou, but Kochou didn't know the other party's identity either." "The Master ordered us to find him with all our might, hoping he will join the Demon Slayer Corps!" "Hmm, I believe everyone will find him," Su Chen agreed.
But secretly, he was deep in thought. Clearly, this mysterious person Kyoujurou spoke of... was Su Chen himself. However, Su Chen didn't believe that Kochou Shinobu hadn't recognized him. Shinobu's behavior that night was very obvious. Su Chen could read her thoughts just from the micro-expressions on her face. She already knew. But Su Chen didn't know why she hadn't said anything.
What concerned Su Chen even more was that he seemed to be a target for Muzan. According to the original plot, he thought, Muzan should be getting rid of the Lower Moons right now, shouldn't he? He wondered if just one Lower Moon Six would be enough for him to kill. Su Chen couldn't help but think about it. Should he create a few more alternate identities? Until he reached the level of Yoriichi Tsugikuni, Su Chen didn't want to reveal his true identity too early.
The sky slowly began to darken. The two chatted for a long time. Kyoujurou spoke a lot about the black-masked person. It was clear he greatly admired the man's skill, even saying that the man's skill was better than his own. If he ever got the chance, Kyoujurou said, he would definitely want to spar with him.
After he finished speaking, Kyoujurou saw that it was getting late. He planned to leave the training grounds with Su Chen and continue chatting on the way home. But as soon as he stood up, he fell back down. Su Chen was sharp-eyed and quickly helped him up. He immediately noticed the injury.
"I'm sorry, Mr. Su Chen," Kyoujurou said with an embarrassed smile. "I got a small leg injury during a mission yesterday." Su Chen was startled, then slowly squatted down. He reached out and touched Kyoujurou's leg. He realized that Kyoujurou's calf was badly strained. Even his bones seemed to be affected. But even with this injury, Kyoujurou hadn't even frowned once while they were sparring. The Hashira are truly amazing, standing tall and firm. Su Chen had greatly underestimated the resolve of a Hashira.
At this moment, Senjuro added from the side, "Big Brother is always like this. Every time he gets injured, I go to the Butterfly Mansion to find a doctor for him. But every time the sisters from the Butterfly Mansion arrive, Big Brother has already left for another mission. Over time, he developed a leg ailment." Senjuro looked very upset as he said this. His earlier hostility toward Su Chen was gone. Seeing his big brother's leg problem, the boy's true nature came out, and he poured out all his worries to Su Chen. Su Chen understood. No wonder the child was so upset when Su Chen was late; he was just worried about his big brother.
Kyoujurou laughed loudly. "Mr. Su Chen, don't worry about me! I just sat for too long and my leg went numb. It's nothing serious. Come, Senjuro, help me up!" Thud. A strong hand pressed Kyoujurou back down. Kyoujurou's large eyes widened. He asked in confusion, "Mr. Su Chen, what are you doing?" "Treating you," Su Chen said calmly. He then gripped Kyoujurou's calf, placing one palm on his knee.
It can be treated, Su Chen instantly judged. Through massage and stimulating acupuncture points, Kyoujurou's condition could be greatly relieved. However, he would still need follow-up treatment at the Butterfly Mansion. After thinking it through, Su Chen began to work. Kanao, who was also there, assisted him from the side. Watching the two of them work so professionally, Senjuro suddenly realized something. That's right! Su Chen and Miss Kanao were from the Butterfly Mansion! Since Su Chen's talent was so amazing, maybe he had also learned medical skills from Lady Kochou? He also remembered hearing from some older Demon Slayers a while ago that there was a male "divine doctor" at the Butterfly Mansion. Su Chen was a male! Could that person be Su Chen?! What if Su Chen could really cure his big brother's ailment? Senjuro looked at Su Chen, and his small eyes filled with a glimmer of hope. He didn't even realize that his opinion of Su Chen had already changed completely.
However, Kyoujurou didn't think so. A person's energy is limited. Since Su Chen had already focused all his energy on his Breathing Style and training, where would he find the time to learn other skills? But Su Chen's actions still made Kyoujurou feel very warm inside. "Mr. Su Chen, there's no need to waste time, I..." "Done." "What?" Kyoujurou's eyes widened, and he subconsciously moved his leg.
