Nine Heavens World, divided into Nine Layers.
Rich in resources, with a multitude of powerful beings, each layer has its own unique characteristics.
After Hei Yang and Bai Yue became enlightened, they explored for thousands of years and eventually discovered the core of the Nine Heavens World, the Nine Heavens Opening Sword.
Upon discovering the Secret Treasure, they refined it on the spot.
Only after refining did they realize that the Nine Heavens Opening Sword was precisely the reason the Nine Heavens World was divided into Nine Layers.
It could open up space and transform worlds.
This was a naturally born Starry Sky Secret Treasure and the foundation of the Nine Heavens World; should any mishap occur, the entire Nine Heavens World could be destroyed.
Thus, even though Hei Yang and Bai Yue were aware of the capabilities of the Nine Heavens Opening Sword, they dared not use it frivolously.
The world itself was their true foundation.
