[Multiple time travelers + no female protagonist + cool story + system sacrifice]

Time Traveler No. 1: I, the third brother of Jinwu, want to build the most powerful demon court!

Time traveler number two: I am the Thirteenth Ancestor of Witches, and I want the Witch Clan to dominate the world!

Time traveler number three: I, King Dong, want to establish the most powerful immortal court!

Time traveler number four: Old thief Hongjun, give me your life!

Countless time travelers descended upon the prehistoric world, claiming themselves to be the protagonists of the prehistoric world. They punched the Three Pure Ones and kicked Zhunti in an attempt to overthrow Hongjun's rule.

Thus, the story of Hongtian, Hongjun's biological son, and many time travelers begins!
