Let me recommend you a few Doujin novels by Detective Conan. I hope you like them: " Detective Conan: The Black Hunter ". Chen Qing had transmigrated into Detective Conan's world. In order to return home, he could only follow the main plot secretly. He realized that this world seemed to be a little different… The main character of Conan: The Fat Otaku Detective was a fat otaku from the outside, but he had the power and wisdom to make criminals unable to hide. He crossed Heisei and Reiwa and dominated the entire detective world. " Detective in the American Manga World " brought the Conan System to the American Manga world and became a superhero with the " Death Possession ". He solved cases and leveled up. He clicked on all of them! In " The Hell Puppet Master in the Conan World ", the Hell Puppet Master Takayoshi transmigrated to the world of Detective Conan. Without the constraints of the overbearing system, he had the advantage of being a prophet in his previous life. He wanted to be the referee behind the scenes in this world. The above is my personal recommendation. I sincerely hope that you will like it.
