In a small southern town at the end of the 20th century, ten-year-old Fu Longsheng became an orphan in a slum after his parents were killed by gangs. He has seen the most naked predatory beasts, experienced the most piercing betrayal, and the obsession of "Only by controlling everything can we survive" has been engraved in the scars of the old injury on his left leg. From a gray apprentice who ran errands for gangs, to a ruthless young man who borrowed knives to kill his enemies, to inheriting the people-knowing skills and information network of the old "Ghost Uncle", when Fu Longsheng was treading a bloody path in the quagmire, his eyes fell on a group of children who were as helpless as he was back then. ——Amu who is extremely strong, Aye who can run faster than the wind, Amo who can nail in the dark all day long, Asuan whose eyes light up when looking at numbers, Aqiao who can open hundreds of locks by pinching a piece of wire, Aying who has a photographic memory of faces, and Ajin who dares to burn the tail of a wild dog with a lighter.
He removed their original names, locked them in an old villa on the outskirts of the city, tamed them with sticks and the occasional apple, and taught them fighting, stalking, accounting, and lock picking according to their talents, in order to sharpen them into the most obedient knives. When the local gravel tyrant "Brother Xiong" threatened, and when the box of antique calligraphy and paintings hidden in the warehouse in Uncle Ghost's notes shone brightly, Fu Longsheng and his seven and a half-year-old children entered the warehouse late at night. The dog barked and startled the guards, the wooden stick broke his arm, A Mo was carried on his back with blood dripping from his eyes, and A Ying's eyes were red from crying when he smashed the calligraphy and paintings. This panic and ruthless first crime made the children's eyes completely hardened, and made Fu Longsheng's "adopted son group" truly a blade in his hand.
Ten years later, no one in the underground world of Fengying City dared to mention Fu Longsheng's name. They only knew that a group of shadowy young people were in charge of logistics and waste products for him.
