Xu Lingyi is a pet mortician with a vicious mouth and a soft heart. One day he awakens to the [All Things Fishing System]. As long as he completes the random tasks issued by the system, he can fish out the spirits of various exotic beasts. But he soon discovered that the mission was getting more and more outrageous: the system asked him to cry to the neighbor's mama's boy, otherwise the golden finger would be taken away. Xu Lingyi did as he was told, but Ma Baonan actually summoned the legendary "Taotie" beast and wanted to swallow the entire building in memory of his mother. Xu Lingyi was forced to test the boundaries of morality crazily while using the strange beasts fished out by the system to fight against the out-of-control mythical creatures. He cursed "this broken system will be finished sooner or later", but he honestly fished out the mythical beast to save the day. In this game between man and beast, system and conscience, Xu Lingyi gradually understood that true warmth is not bottomless tolerance, but love that dares to break the abnormality.
