As for the Cave Mansion Spiritual Treasure, the lowest are Tier Seven Spiritual Treasures.
What's the background of that Nascent Soul Cultivator outside? He actually possesses a Tier Seven Spiritual Treasure?
In shock, a surge of greed arose in Si Ze Demon Venerable's heart. If he could kill that Nascent Soul Cultivator, the Cave Mansion Spiritual Treasure would become his own possession.
With this Spirit Treasure, one could almost claim to be invincible within the same tier. Even if not a match, with this treasure for protection, not even a cultivator one tier higher could kill him.
The more he thought, the more excited he became. Si Ze Demon Venerable's eyes were bloodshot, yearning to burst through the Spirit Treasure's seal to kill its owner.
However, this Grotto Heaven Spiritual Treasure forms its own realm, with Heaven and Earth as its walls, and there is simply no exit.
