Demon Slayer: My Zanpakutō Is the Nichirin Sword

After traveling through Demon Slayer, Lin Ye awakened the strongest Shinigami system. Looking at the ghosts who were mistakenly judged as "virtual", he showed a kind smile - how could these be evil ghosts? It's clearly a walking experience gift package! When Oniitsuji Muzan returns from rebirth—— Was it frustrating to lose in your last life? In this life, he decided to change his approach. Summarize lessons and optimize management: add blood to Xixian crazily, provide love counseling for Yiwozuo, order Tongmo to eat properly, and relieve the anxiety of Heidi Mou's appearance.

Butterfly Ninja: "Brother-in-law, can I come to your room tonight to help me detoxify?"
