Start Trading from Demon Slayer

He, Lin Yi, a young and beautiful male college student, accidentally entered various animation worlds. If you want to go back, you need to make four transactions with characters in each world? Is it the distortion of human nature or the loss of morality? In order to return home, the protagonist breaks through the lower limit again and again. In the world of Demon Slayer, Tanjiro's tears, anger, and wails are reserved for the departure of the one he loves. In the world of Naruto, Naruto wears the Akatsuki robe and vows to create a truly peaceful world, even if he spends his whole life. In the world of spells, Huzhang looked at the figure in his mind and murmured softly, looking dazed. "If nothing can be done, leave it to me." The boy hugged those people, their figures reflected in his bright golden eyes. Please tune in to watch the new work sponsored by the author, which is updated every night at 6pm, starting from Demon Slayer. (It deviates significantly from the original plot, contains OOC, and the protagonist's ability is dragon. The CP will not be broken.)
