Datang: God level bear child

Li Chengfeng, a scientific research genius in the 21st century, passed through the Tang Dynasty and turned into Li Shimin's six-year-old son? In the God given bear child system, Li Chengfeng pulled Li Shimin's beard and started the game against Fang Xuanling and Du Ruhui, but they had nothing to do about it. Li Chengfeng used his talented scientific knowledge to solve the natural disaster by diverting water from the south to the north. The hybrid rice he developed can yield 2000 Jin per mu. Exterminating Turks and subduing Koguryo, Li Chengfeng was granted the title of king of the Tang Dynasty at the age of six. It can be said that there is no bosom friend ahead. Who in the world doesn't know you?
