Didn't you say that the Devouring Beasts can't be killed?" Mark: "He is more suitable to be the city lord than me." Charles: "He is the messenger sent by the Lord of Light and Shadow to save the doomsday, the true savior!" Bai Yuekui: "Only in front of him can I find the humanity that I once lost."

The author not only writes about what happened to the protagonist in the anime world, but also uses a lot of writing to write stories about characters from the anime world traveling back to the protagonist's original world. The worlds this book is currently expected to travel through include [Spiritual Cage], [Under One Person], [Naruto], [One Piece], [Spell Return], [Marvel Series], [Pacific Rim], and [One Punch Man]. The writing order does not refer to the above sequence. In the later period of the book, the original world will have spiritual energy revived, but there will be no elements of immortality. In the early stage, the original world will still be a normal urban cool life. Newbie writing a book, please bear with me
