[Cultivation Levels: Initial Realm - First Realm - Second Realm - Third Realm]

Yun Bai stood at the pinnacle of the cultivation world and looked back on his past. He had once leaped into a black hole and transmigrated to the cultivation world. He had once forcibly refined his Golden Core into a black hole. He had once conjured black holes with his bare hands and wreaked havoc in every direction. After finally surviving his tribulation and ascending, he truly cultivated himself into a black hole! When the density of a celestial body gets too high, it becomes a black hole. So, if the spiritual energy density inside a cultivator gets too high, do they turn into a black hole too?
