Li Dashan (25 years old) was born in rural China in the 1990s. He is hard-working but comes from a poor family. Occasionally, due to a lightning strike, he traveled back to the Kaiyuan period of the Tang Dynasty and possessed a young farmer with the same name. With modern agricultural knowledge, craft concepts and practical common sense, he gradually made a fortune in the Tang Dynasty.
During the Kaiyuan period of Emperor Xuanzong of the Tang Dynasty, society was stable, the economy was prosperous, and folk handicrafts and commerce began to flourish. It was the "golden age" for entrepreneurship and wealth.
The modern rural boy changes his destiny with the help of modern knowledge → helps the villagers get rich → deals with the powerful → builds a family business → becomes the richest → marries multiple women from different backgrounds, forming a big family structure of "ten houses and ten personalities".
