[No system] [Single female protagonist] [Logic online] [Decisive killing] The people on earth traveled through time and came to the ancient world, and turned into a purple snake of ordinary blood. In the prehistoric world, there are constant disputes. The world is like a furnace. Once you are in it, it is difficult to be alone.

The changes in the world also indicate many unknowns. Even so, Chao'an is still trying to gain a foothold in this strange and primitive world, and become a dragon.
