Great Chaos Eye

The Great Spirit has strange abilities when he travels back in time. This world is very strange. It feels like everything is revolving around him, like... He's making a game? This is an extremely large feudal dynasty, but it has a real human emperor and a golden dragon of luck (but a black one), and the practitioners are used by the court. The gods in the sky are eyeing the powerful human empire, and the underground is a world of life and death. What can you do with a small Chaotic Eye?
