During the day, he was a low-level deliveryman riding a dilapidated electric bicycle in heavy rain. He was looked down upon by his wealthy in-laws for his sister's life-extending money. At night, when the whole city fell into an eerie silence, he held a rusty ancestral iron needle in his hand, could see through life and death with his left eye, and walked in a copy of the dark side that no one dared to visit.
The Su family thought he was dirt that could be trampled on at will, forcing him to cleanse himself and leave the house; the clan thought he was an ant that could be easily pinched, and set up a situation that would lead to his death.
But they don't know that he has the final say in this city's night. When the silver needle enters the acupuncture point, it not only saves the common people, but also kills gods and demons.
