Doomsday Shelter: I Can Combine Anything

Worlds merge, and apocalypses pile up In 2037, Bai Lin transmigrates to a parallel world. At first, he thinks it is just an ordinary modern city. Then, only two days after his arrival, the Blue Star Federation announces to the world that a comet will strike Blue Star in one month. It declares a global mobilization and calls on all humanity to build shelters and preserve the seeds of civilization. Just as despair sets in, Bai Lin awakens a synthesis interface: by spending source points and materials, he can synthesize anything. Before the smoke from the comet crisis has even cleared, one disaster after another arrives. Extreme cold, extreme heat, geological disasters, and nuclear winter push human survival to its limits. Even more terrifying are the twin moons that suddenly appear in the sky, and a strange bio-weapon virus. It can infect corpses, humans, and animals, turning them into zombies that retain their original intelligence and continue to evolve. Can't find a reliable, worry-free companion?
