The Great Celestial Master of Tokyo

Li Xuan transmigrates to Yingjing, a parallel world, and obtains the Celestial Master Apprentice System. To his surprise, his first problem is a girl named Yotsuya Miko, who has the Yin-Yang Eyes. Evil spirits are always appearing around her. What's more, her home exudes such intense yin energy that it feels like a ghost realm, and Li Xuan doesn't dare go anywhere near it. At the same time, Li Xuan attends the high school division of Uomori Academy. He never expects that after nine at night, it turns into a spiritual realm and attracts hordes of monsters. His beautiful classmate Yukimura Tokine turns out to be a barrier master who protects the area. After finally getting a little time to rest, he joins a school trip to the countryside, where they go camping and encounter all kinds of monsters. Among them is a chubby cat spirit whom Li Xuan recognizes. “Isn't that Nyanko-sensei? I know him! So this is the world of Natsume's Book of Friends!” Once Li Xuan confirms the world he has transmigrated into, one day, he spots a dog demon at night. “Inuyasha???” “What kind of world is this??” A crossover world where anime series converge. The story is a slow burn.
