Caught in a flood, Gao Yue, an overweight young woman weighing 160 jin (80 kilograms), accidentally falls into another world. Right from the start, she plunges into the sacred lake of the Nether Python Tribe, surrounded by giant pythons. The beast world is full of dangers, but luckily, she encounters the extraordinarily handsome Mo Ya from the very beginning. Gao Yue shamelessly pretends to be a little cub, hoping to win her way out with cuteness. In response, Mo Ya begins pursuing her relentlessly.
