One Billion Years of Prehistoric Evolution

He traveled through time and became a cell in the prehistoric world, becoming a life form in the prehistoric world in the true sense. At this time, Lin Jiyuan looked at the world: What's going on? Why are the cells on the opposite side sending shock waves? Damn it, why are there five-clawed golden dragons in the sky? This is a nightmare in a science fiction world, a prehistoric world! It's just that the timeline of this time travel seems a bit early. Why are dragons, phoenixes and unicorns still fighting in the outside world, and the ancient heaven has not yet come out? However, destiny is destined in the wild, but where is my path? If there is no way, then use your countless selves to fight for it! If Tiandao has no place of its own, then use unlimited time to play a game of chess with Tiandao using yourself as a chess piece!
