Demon Slayer: After Penetrating the Body of the Ghost King

[Two male protagonists, main attack, if nothing else happens, the cp will be flawless] One day, Muzan Ahara penetrated into the body of the demon slayer villain from the comics he had read. As a social animal, Huang Yuan's heart felt like death, and he had not spent all the money he had saved. Sure enough, someone with the same name will wear it? ! No matter what, let's live on in the ghost king's body first. As a ghost, you can only live in darkness without seeing the light? Then let humans accept ghosts by force! As a ghost, you want to drink blood? Legalize the sale of blood! As a ghost, you can't touch the sun? Then build a city of eternal night! Met an original character? Catch him and go to work! Twelve ghost months? Not for those who are illiterate! Don't let those who don't know how to settle accounts! Demon Slayer Squad? Sign a contract to be a bodyguard! One day, the soul of the original ghost king woke up in his body... Wasteland Wuxian: Ah, that cowardly and stupid ghost woke up Ghost Dance Tsuji Muzan: Get out of my body! Wasteland Wuxian: A useless and disobedient guy who only causes trouble, he needs to be trained well, lol)
