Once he traveled through time, Li Tai became Li Shimin's favorite young son Qingque. He was bound to the demon-making system and became stronger the more he tried! Other princes were gentle and well-read, but he was the only one who did not follow the ordinary path. Digging crystals out of latrines, refining black powder, and making flying god fire crows, all in one way or another. The gentle and protective Empress Changsun connived at the whole process, and the cold-blooded emperor Li Shimin was repeatedly manipulated by his traitorous son. He had his dragon robe blown up, tricked the ministers, peeked at the secret recipe, and was ridiculed. A four-year-old child possesses encyclopedic knowledge and top-notch skills. He unlocks god-level abilities by constantly doing things, and suddenly creates a new situation in the prosperous Tang Dynasty!
