A 28-year-old graduate student in political science and law, he was deeply involved in legal logic, chain of evidence deductions, and the game of pros and cons in human nature. He died suddenly from overwork while preparing for the civil servant examination. He was extremely rational, abiding by rules, understood the bottom line, and knew how to adapt.
No system, no plug-ins, no chance from heaven. Purely natural gift of photographic memory + modern rule logic, human game, and legal thinking of political and legal graduate students, the whole process relies on poor cognition, logical deduction, and rule-breaking counterattacks.
