Sign-In System: Starting from Resident Evil

Armed with a mysterious sign-in system, Lin Yu traverses infinite worlds—from the zombie apocalypse of Resident Evil to the cosmic battles of Marvel, from the mythic Journey to the West to the Transformers universe. Alice calls him her hero. Captain America questions his humanity. Even the Monkey King doubts his legendary staff. But Lin Yu just wants a quiet life... so why does every world keep throwing beautiful women at him? One check-in at a time, he's rewriting the rules of reality itself.
