Teacher Lineage: Three Thousand Years of Teaching Began with Dayu's Flood Control

My name is Gu Gu, the valley of Guigu. I traveled through it in 2099, and my soul passed through the "valley" of the craftsmen in the Dayu era, and started a three-thousand-year teaching career. In order to avoid the erosion of the netherworld forces and complete the closed loop of history, I must guide the process of each era. I believe that the essence of teaching is not to impart knowledge, but to ignite the fire of thought.
