Lin Chen is a top-tier logical strategist in the real world, skilled at predicting human behavior and dismantling traps hidden in rules. Meticulous, calm, and cunning, he never acts impulsively and wins through intelligence. His physical combat abilities develop later, while in the early stages, he overwhelms his opponents through sheer intellect. His adversaries include prodigies from various fantasy worlds and veteran strategists with years of experience. All are extraordinarily powerful, yet easily ensnared by traps hidden within the rules. The system speaks in a cold, mechanical voice. It gives the protagonist no effortless cheat abilities; it only issues missions and announces rules. Every condition for clearing a game is concealed within loopholes in those rules, which Lin Chen must uncover himself.
