Shen Mo, the illegitimate and abandoned son of the richest man, has been struggling in the market since he was a child.

After awakening his "market tycoon" personality, he can negotiate tens of billions of projects using vegetable market bargaining techniques, and rely on his scavenger connections to fight against capital giants. The scar on the wrist symbolizes the 'lower class' status defined by the powerful class, and ultimately uses the old city as a chessboard to subvert the rules of the wealthy family.
