Li Shou, nicknamed the "Door God", appears to be an ordinary doorman in the urban community "Yujingyuan" holding a thermos cup and copying the duty list. Hidden under the security uniform, he is actually a hidden descendant who can wield the ancestral "door-suppressing ax" to slay demons.
One rainy night, a smelly black mist suddenly poured out of the underground garage of the community. A "bone-eating beast" with exposed fangs tore the garage door apart and was about to pounce on the residents who were returning late. Li Shou didn't have time to think too much, he picked up the rusty gate ax next to the gate post. In the horrified eyes of the residents, the ax blade struck out a golden arc of light - he actually cut off the monster's claws with one knife, killing the evil thing hiding in the shadows of the city on the spot.
Since then, the reputation of "Door God" Li Shou has quietly spread: he patrols late at night to kill "shadow demons" to protect the peace of the community, captures "qi-devouring monsters" with his bare hands, and saves the old man next door. Even the Bureau of Mysticism came to ask him to help investigate the mystery of the frequent occurrence of urban monsters.
No one knows that Li Shou's gate ax hides the secret of "guarding the human world", and that the underground of the community he protects is connected to the "crack gate" where monsters invade. When a larger wave of monsters approaches, this doorman with a thermos cup will use his hand ax to open a path to protect all living beings in the reinforced concrete city, transforming from a community door god into a city guardian!
