With the blessing of the sun, he came to this world full of evil spirits, was picked up by the Demon Slayer Corps, and became the strongest pillar. Watch him solve the chaos of evil spirits that has lasted for thousands of years.

Luochuan woke up and came to the world of Demon Slayer.

Together with Zenitsu, he was picked up and raised by the Pillar Jigoro Kuwashima.

However, he did not have the talent to practice breathing techniques, so he could only learn Thunder Breathing from Zenitsu.

Lin Yan traveled through time and space in the blink of an eye. He traveled to the world of Demon Slayer, to the body of a dying beggar. The wind was freezing cold, and Lin Yan had no strength at all. He could only huddle in a corner, feeling the vitality in his body gradually disappearing in despair. As a traveler, he even had the golden finger [a system that can make you stronger by eating], but he had no chance to use it. After all, the reason why he fell into such a situation was because he had nothing to eat. At this moment, a pair of slightly immature hands full of wounds pulled Lin Yan up.

Shenyuan Ziye's soul traveled to the world of Demon Slayer, awakened the Ice Breathing Technique, and obtained a system that allows him to level up by killing demons!

After traveling back in time for two and a half years, his parents were killed by evil spirits. Shenyuan Ziye was heartbroken and decided to join the Demon Slayer Corps. After becoming Bingzhu, he began to kill demons wantonly!

Tanjiro Kamado: Yes! Mr. Kamogen is a very powerful person!

Agatsuma Zenitsu: Kamigōnen, is work the only thing on your mind?

Inosuke Hashibira: Damn it! I can't surpass you again? Moonlit Night!

Shenyuan Ziye: Even if my body is destroyed, I will definitely kill the evil ghost!
