[Demon Slayer + Systemless + Passionate Blood + Brainstorming] Traveling through the world of ghosts and demons, Lin Yan started dissecting ghost corpses and was regarded as a madman by the whole team.

Are more deadly than insect breath." Tomioka Giyu silently handed over the kettle; Purgatory Anjuro patted his shoulder and laughed: "Next time we will fight together!" When Wu Kuan roared "Science is actually scarier than magic", Lin Yan raised the syringe: "This shot is for all the ordinary people who are eaten by you."
