Let You Guard the Dock, and You Will Control the Life and Death of All Worlds.

[Doomsday Port + Survival by Rules + Hardcore Deduction + Group Image Growth] After the disaster struck, the port city struggled to survive amidst the ruins. And at Pier 7, where Cheng Ye is guarding, every night, a ship that doesn't belong to this world may arrive. They come from worlds that have been destroyed, or are in the process of being destroyed. The ship may contain survivors, technology, resources and the last legacy of a civilization. There may also be hidden infections, monsters, weird rules, and things that are enough to make the world end again. Cheng Ye is the only one with the right to guard the gate. Admit, isolate, limit contact, or reject outright. Open the door and maybe save a boatload of people. He might also bring about the end of another world with his own hands. What's even more troublesome is—— Every ruling cannot be revoked. Every ship left behind will truly change Pier 7. Until late one night, communication sounded again on the sea. "Pier 7, please dock." "How many others are on board?" "47." "What about your world?" There was silence on the other end of the communication for a long time. "... No more." Cheng Ye raised his head and looked at the approaching ship in the darkness. "Don't open the door yet."
