The world suddenly fell into doomsday, and all civilized order collapsed. Let's see how the team of survivors led by Du Xiaofei rushes left and right in the ruins, encounters all kinds of human weirdos, external survivors, supermarket undead, loli robots and other strange forces. They use jokes and wisdom to fight against the devastation, the team falls apart on many fronts, and finally rebuilds hope in the catastrophe. The three volumes of stories are independent but intertwined with each other, with multiple plots running in parallel. They include collective adventures and delve into personal growth and human redemption. The humor is full of profound meaning - even if the end comes, you must still live with laughter and tears.
