Prehistoric: the Road Travels Alone

This is, prehistoric? The law of the jungle and the survival of the fittest are vividly demonstrated here. And I, Ji Xiao, came here to see the human race crawling for survival; to see if the Three Pure Ones were merciless; to see if the way of heaven was unkind. The power of heaven is coming, where should I go? Ps: This is my first time writing a book, so please bear with me. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
