Yanshan Hall was located halfway up the main peak of Yanshan, close to the top of the mountain.
Under the dark purple sky, the golden glazed roof of the palace appeared extremely glorious.
The red walls were engraved with countless flying eaves and beasts, as well as mysterious runes and curses.
It combined with the jade-white stone steps outside, the exquisite corridor, and the towering ancient trees planted inside.
It formed a special array called the [Two Elements Illusionary Heart].
Once they attacked this palace, they would be able to escape.
Or they had touched an important restriction inside.
The formation would instantly activate, pulling all the enemies into an illusion filled with danger.
Even a Quasi-Saint would find it difficult to escape in a short time.
Just by looking at this array, one could tell the special status of Yan Mountain Hall above all the other palaces.
