Starting from the River Styx, Build My Empire of the Underworld

Traveling to the prehistoric world where chaos first emerged, when you open your eyes, it becomes the Styx bred by the sea of ​​blood. At that time, Hongjun had not yet preached, the saints had not yet appeared, and the two tribes of lich and demons had not yet stepped onto the stage of fighting for hegemony. The whole ancient world was full of opportunities, but also hidden dangers everywhere. Styx, who had just crossed over, originally thought that the prehistoric world was a world where the strong were respected. Without strength, he could only become a stepping stone for others. But a trip to the ancient times made Styx understand the secret of killing, and climbing Mount Buzhou made Styx understand the mystery of reincarnation. With these unique conditions, Styx is determined to carve out a world of his own based on the sea of ​​blood.
