Great Tang: Li Er Discovers Me Through His Simulations from the Start

Li You transmigrates and becomes Li Shimin's fifth son. He plans to stockpile provisions, build strong walls, bide his time before claiming the throne, and keep a low profile. But unexpectedly, Li Shimin obtains a national-strength simulator that can predict increases and decreases in the country's power. When he simulates Li Chengqian, he sees disaster after disaster: Li Chengqian indulges the musicians of the Imperial Music Bureau and eventually launches a rebellion, weakening the nation. When he simulates Li You, he finds that the boy is utterly unruly, yet the national-strength simulator always predicts that he will make the country stronger. Li Shimin can't understand why, but he trusts the simulator. Li You wants to keep a low profile, but Li Er keeps exposing him with uncanny accuracy.
