I Created Civilization in Ancient Times

Reborn back to ancient times, let's see how the protagonist opens an era of his own in ancient times and builds his own world in the ancient times where hair and blood drink blood. Readers are welcome to give me some advice if the content is not well written. Please be merciful to new writers. I give readers a fist here. The introduction is short and weak, so please move on to the main text to read. If you don't know how to be a eunuch, please support me. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
