Please recommend the title of a Doujin novel with a comprehensive theme.

I want to find the name of a manga doujinshi novel. In the novel, the male protagonist is not old. At the beginning, he transmigrated to Inuyasha and met a baby who almost died. The male protagonist used his blood to save Shoushimaru. Then, he was brought back to the West by Inuyasha and became Shoushimaru's master. Finally, when he left Inuyasha's world, he used his own bones, blood, and skin to make a pair of daggers or something. Later on, he transmigrated to Naruto. When the Naruto Summoned Beasts appeared, they were all scared to death. Everyone, may I ask, which one is this?

Answer 1

I recommend "Comics: The Descent of the Contract God". The plot of this book spans across multiple comics worlds. The protagonist obtains extraordinary powers by signing a contract with the gods and leads the heroes of each world to conquer the evil forces of each world. I hope you like this fairy's recommendation. Muah ~😗
