Chronicles of Things in the Prosperous Tang Dynasty

I, a high school physics teacher, dressed as the abandoned prince Li Chengqian who fell off a horse and lost his leg. The imperial doctor concluded that I would become a cripple, my younger brother Li Tai waited for me to be deposed, and the civil and military officials in the court regarded me as a laughing stock. I took out the plaster bandage with my backhand and put the first plaster on myself in the Tang Dynasty in public. They called me "witchcraft", but I turned around and used the lever principle to build a wheelchair, and used the pulley block to innovate the crossbow. They accused me of "strange and obscene skills", but I casually promoted fried grasshoppers and resolved the locust plague that swept through Guanzhong. When Li Tai presented the magnificent work "Kuo Di Zhi", I presented scale maps and drawings of red cannons. Li Shimin looked at my model of a hot air balloon that can carry people into the sky with complicated eyes: "Chengqian, tell me, is this prince position worthy of you?" I smiled slightly and pointed to the starry sky: "Father, my next step is to pick a star for you."
