Modern corporate slave Lin Yan suddenly passed away from staying up late working overtime. Upon opening his eyes, he unexpectedly traveled through time to the Dajing Dynasty, becoming the playboy only son of the Minister of Revenue. Accidentally awakening mind-reading abilities, he can clearly hear the calculations and sincerity in others' hearts, thereby escaping his reputation of being a good-for-nothing and moving step by step with caution. Using mind-reading, he exposes the traps of fair-weather friends, helps his father resolve court crises, roots out corrupt treacherous ministers, overthrows arrogant generals, clears the names of wronged generals, and assists a wise monarch in protecting the common people during troubled times. From a playboy marquis's heir to a powerful court official, Lin Yan relied on his own wisdom and special abilities in an unfamiliar era to walk out a path of counter-attack that belongs to him, also reaping the warmth of lifelong companionship.
