The apocalypse descends, monsters swallow the city! Lin Che is trapped on the 32nd floor, but unexpectedly awakens the shelter system. While others fight desperately for a bite of food, he relies on material trading, quest rewards, and demon hunting to level up, turning an apartment into a safe zone that survivors rush to join! He Yong, Su Jianing, and others join successively, and neither giant spirits nor beast tides can stop the pace of expansion. But no matter how many people he saves, his out-of-contact parents and grandparents remain a thorn in his heart. The demon hunting team finally slays their way back to their hometown, and what greets them turns out to be a sky-covering giant tree, with a mysterious dragon egg hidden within the tree. In this apocalypse, just how many incredible existences are still out there?
