Lin Yu, a 28-year-old programmer at a gaming company, is a passionate fan of history and political strategy games. He spends his days immersed in virtual worlds, directing armies and shaping the fate of kingdoms. One day, after working overtime, he falls asleep at the office from exhaustion. When he wakes, he finds himself in a glittering palace, with everyone around him shouting, “Your Majesty!” Before he can even react, a group of ministers rushes in to report urgent problems, from border conflicts to a fiscal deficit. Only then does Lin Yu realize that he has transmigrated into the body of an ancient emperor.
