I Rebuilt Human Civilization

Ren Yifan travels back millions of years. At that time, the human embryo had just been brought to the Blue Star by the Holy Maiden of Mars. It was eating hair and drinking blood and had not yet learned how to use fire. I thought it was an extremely backward Stone Age. Who would have thought that it would be a chaotic era where aliens are eyeing you, orcs are everywhere, the evil god of chaos enchants Zhongliang, and humanity is in dire straits! Ren Yifan relied on the Martian Saint's family business on Blue Star to rise from the bottom and rebuild human civilization step by step! Became an emperor respected by thousands of people! "Everything is for the Emperor! I am willing to dedicate my absolute loyalty to the Emperor!"
