Lu Li finally had an understanding of the Heaven Reverse Universe after Jiang Wuwo's explanation.
The historical course of humans could be divided into the distant ancient times, the middle ancient times and the contemporary time that is now. The distance ancient times was a history of blood and tears for humans when humans were regarded as animals and slaves. Humans trembled at the awe of other alien races, being killed by the races randomly and even taken as food.
In the middle ancient times, humans began their rise secretly. With Bloodline Skills, humans began to develop Xuan Skills and comprehend nature's rules and Profound Meanings. Back then, humans were still weak. But at least, they could protect themselves.
