Eight years ago, genius ring Wang Tangfeng was betrayed by his best friend He Ming and plotted against him in a key match. Not only did he lose the championship, but his wife died in childbirth. When he was desperate, he entrusted his newborn son Tang Xiaobao to his master, and he became anonymous and became the lowest level cleaner in the ring.
Eight years later, when Tang Feng was mopping the floor beside the ring, a child named Tang Xiaobao suddenly rushed onto the stage, hugged his leg and shouted "Dad". This son, who is gifted with a photographic memory, secretly signed up for the youth competition behind his master's back. What shocked Tang Feng even more was that his son's opponent was the daughter of He Ming who betrayed him.
Faced with this sudden change, Tang Feng was forced to return to his old career and guide his son in the ring as a coach. But He Ming is no longer what he used to be. He is not only a giant in the ring, but also holds the evidence that Tang Feng was framed back then. The father and son must join forces to fight their way through the world of overt and covert arenas.
However, a deeper conspiracy is emerging - the death of Tang Feng's wife seems to be more than just a difficult childbirth...
