Li Ke, a graduate student in the Department of Modern History, traveled through time and became an "alternate admonisher" in the early years of Zhenguan, and was accidentally bound to the "Emperor's Tucao Come True System" - as long as he madly complained about Li Shimin's decision-making in his heart, and if the complaint involved "waste of resources" or "decision-making loopholes", the system would automatically generate an optimization plan, and Li Shimin could clearly hear his inner complaints. What's even more absurd is that every time Li Ke helped the court save money by complaining, he could exchange it for hard-core props such as "Qu Yuan Plow Drawings", "Potato Seeds" and "Simple Cement Formula".
