Ask Nu Wa how to get there!

You can get two Nuwa stones (you can definitely get them) after the level 80 demon road mission. Running the ring has a certain chance to get Nu Wa. It is said that the 90th ring is more likely to get Nuwa than the 60th ring. If you kill the god of wealth, you can also get Nuwa, provided that you can't give it to everyone in the team every time you fail. Dig for treasure.
