Modern transmigrator Lin Changce becomes the study companion of Dayu Empress Ji Wuyou. The Empress accidentally activates the Dim-Witted Ruler System, single-mindedly wanting to exhaust the national fortune and ascend with the entire country; meanwhile, Lin Changce unlocks the Virtuous Minister System, where boosting the national fortune allows him to cultivate immortality and attain the Dao. Thus, the Empress goes wild making crazy moves—squandering huge sums on disaster relief, building the Tower to Heaven, indiscriminately issuing fiat currency, and even personally leading troops on an expedition. Yet Lin Changce, relying on supreme strategy and immortal arts, turns all of the Empress's so-called "bad moves" into eternal grand achievements that benefit the country and the people, sending the national fortune soaring all the way! In the end, the Empress's hope of ruining the country is completely dashed, and amidst hilarious contrasts of mutual affection and rivalry, the two join hands to pacify the realm and jointly govern the prosperous era of Dayu.
