Completed two million words of the old book 《The Tang Dynasty's Scholar During the Zhenguan Era》. Li Zheng in Chang'an was expelled from the school because he was too stupid, and many people thought he was an abnormal person. When he solved the Nine Chapters on the Mathematical Art, and broke the battle situation of Yin Mountain, the whole of Chang'an was looking for him... Years later, he opened up a new agriculture for the Tang Dynasty. He built the scientific foundation for the Tang Dynasty. He controlled the lifeblood of the entire Tang Dynasty's commerce... One day, Li Zheng said to him: "In your perception, I may be a prophet, maybe I am smarter than all of you, what I give you is just a casual thing to do, you don't need to be grateful to me, and don't expect me to submit to you."
