Honghuang: in the Beginning of Rebirth, I Will Destroy the Demon Race!

[Prehistoric] + [Multiple Systems] + [Multiple Travelers] + [Avenue Brawl] + [Invincible] Qin Xuan traveled through the prehistoric times and became a prehistoric human race. He activated the invincible sign-in system at the beginning, but... In just three days, the human race suffered a catastrophe and was swallowed up by a tiger monster! When I opened my eyes again, I traveled through time twice and became Yuanshi! From then on, Yuan Shi vowed to destroy the demon clan... Hongjun blocked him and was directly hit to death! If the road is blocked, suppress it directly! Are there any other system owners and time travellers? Sorry, all the systems have been taken off, all the male time-travelers have been killed, and all the female time-travelers have become harems! See the main text for details, there are so many cool points...
