Chapter 1627 - Chapter 631: Civilizations Cycle_2

On that stone stele, a record was etched detailing an interstellar war between the Cultivation Civilization and aliens. In the chronicles by someone named Xuanhuangzi, the enemies who fought against the Cultivation Civilization were referred to as Outer Demons. These Outer Demons fought by operating massive steel machines against cultivators. Xuanhuangzi's description of the Outer Demons was identical to the depiction of the Human High-tech Civilization fighting against the Ape Tribe, suggesting the enemies of the Cultivation Civilization were also the Human High-tech Civilization possessing Space Fortresses.
