Ye Xiao, a former professional rock climber, lost his beloved girlfriend and his trust in the world due to a manipulated "accident" when he fell off a cliff. After being reborn three years ago, he was bound to the "Absolute Control" system. As long as he had a strong desire to possess the target and exercise control, he could strengthen his physical strength and perception. In this life, he no longer pursues gold medals, he just wants to completely crush the mastermind behind the scenes - the underworld boss "Viper" who dominates the underground boxing world. Ye Xiao transformed into an underground boxer, fighting violence with violence and dominating the arena with a suffocating sense of oppression. However, as the investigation deepened, he discovered that "Viper" was just the tip of the iceberg, and the entire sports world had already been infiltrated by the underworld. In the fog of strong suspense, Ye Xiao's possessiveness gradually got out of control. He not only wanted to possess the victory, but also the truth, even at the risk of dragging those around him into a dangerous cage. This is an extreme game about revenge, control and self-salvation. Every punch is a rebellion against fate.
