For a hundred years since the beginning of the universe, Mutong had never sacrificed and refined to enhance his own world.

He was communicating with the spirit beast. The spirit beast could advance with its master, especially the master's world.

A ninth-grade spirit beast could open the mysterious realm. If the spirit beast could participate in the advancement of the monk's own world before the ninth grade, it would be of great help to promote the ninth grade and open up the mysterious realm.

And if there is a spirit beast participating in the sacrifice and refining of the cave world, the cave world can also gain a bit of the spirit beast's illusory and real Dao charm, with a stronger foundation and power.
