MTL - Qing Dynasty: Pampering The Queen - Chapter 4263 question

Li Chengfeng, a scientific research genius of the 21st century, traveled through the Tang Dynasty and turned into Li Shimin’s six-year-old son?

  In the god-given god-level bear boy system, Li Chengfeng grabbed Li Shimin’s beard and started mad at Fang Xuanling and Du Ruhui, but there was nothing they could do about it.

  Li Chengfeng used his genius scientific knowledge to solve natural disasters by diverting water from the south to the north, and the hybrid rice developed by him can produce 2,000 catties per mu.

After destroying the Turks and subduing Goguryeo, Li Chengfeng was conferred the title of God King of the Tang Dynasty at the age of six.

It can be said that Mo Chou has no confidant in the future, who in the world does not know the king?
