In modern society, demons are rampant, and various sects send disciples to protect mortals in the city. Zhang Ran, as a mortal disciple of Longhu Mountain, was sent to Beining City to perform the task of exterminating demons and subjugating demons.
After Zhang Ran came to Beining City, he carried out the task of exterminating demons and subduing demons while adapting to urban life. In his contact with various monsters, he discovered that not all monsters are evil, and some monsters also have human feelings. He began to re-examine his mission, and finally found a balance between protecting mortals and understanding demons.
