I recommend the following two novels from the prehistoric times to you: 1. " The Reborn Me Becomes the Eastern Emperor Taiyi ": A modern man who was reborn as the demon emperor of the primeval era. He watched Nüwa create humans, diverted the disaster to the west to survive, and changed his fate. 2. " Reborn in the Primitive World: Zhunti ": The story of a young monk who traveled to the legendary Primitive World and became one of the two ancestors of Buddhism, Zhunti.
