Ordinary college student Li Xuan unexpectedly acquires the dream space ability to shuttle between parallel doomsday and the real world. In reality, he bids farewell to twisted relationships and quickly accumulates wealth by using the gold, silver, and jewelry scattered everywhere in the doomsday world, turning the tables to rewrite his life. In the doomsday, zombies run rampant and crises lurk everywhere. While hunting zombies to obtain crystal cores to strengthen himself and collecting supplies, Li Xuan gathers survivors to form a team. As powerful base leaders and high-tier mutant zombies appear one after another, the adventure in the dual worlds begins, and he will continue to grow stronger in both planes to face repeated life-and-death tests.
