After ordinary worker Lin Xiao was dumped by his snobbish girlfriend, he unexpectedly obtained a space ring capable of traveling across myriad realms. He befriended Chu Yaoyao, an apocalyptic survivor, trading cheap modern water and food for large amounts of gold, jade, and physique-enhancing beast cores. In reality, Lin Xiao formed a bond with down-and-out campus belle Su Miaomiao and ice-queen female CEO Jiang Chuning, forcefully slapping his ex and workplace enemies in the face. As the space upgraded, he also connected with a saintess of the immortal cultivation world, opening up a wonderful new trade. Meanwhile, a beast tide broke out in the apocalyptic world, and Chu Yaoyao fell into a desperate plight; Lin Xiao spent a huge sum of money to buy a pickup truck, preparing to personally cross realms to stage a desperate rescue.
