Find a Hill to Be a King

Chen Zuo, a high school graduate who is at the peak of human IQ, accidentally traveled back to ancient times. The population is sparse and the land is barren. Chen Zuokong has a wealth of knowledge that can benefit the people, but he is unable to put it to use due to limitations of the system and productivity. I wanted to find a place on a hill and become a mountain king, but the current situation was turbulent and I was involved in a turmoil. In the end it didn't work out.
