In the old town of SY City, LN Province, Lin Feng is a contradictory existence - he is the top student in the second grade, and the formulas on the calculation paper are as accurate as the trajectories on the basketball court; he has a strong body like James, but he always hides the old basketballs he picks up in the debris pile, and only practices alone in abandoned factories late at night.
The agreement he made with his childhood sweetheart Su Qingyi was the motivation for him to study until late at night - the two of them made an appointment to step into the gate of Peking University. The tea eggs in the canvas bag and the annotations between the pages were the cleanest bonds in youth. But Brother Tiger's switchblade at the school gate and the arrogance of the gangsters in the market made him see the reality clearly: scores and skills alone cannot protect the people he wants to protect.
When the "Uncle Long" from the underground world stopped outside the factory and filmed the moment when he took off to shoot, Lin Feng's life trajectory quietly changed. Should he continue to follow the established path of academic dominance and go to Peking University with Su Qingyi? Or should you hold onto your basketball and your fists, step into the dark world, and use another way to protect everything you cherish?
From the rusty old basketball to the storm that stirred up the underworld in Dragon Kingdom, this poor boy from SY City will use his wisdom and strength to find his own path to become the "Prince of Underworld Basketball" in the examination room, the court and the rivers and lakes.
