The origins of the jade seal were mysterious, and the benefits it provided were immense. After the second layer, it still had some energy left, allowing Owen Bertram to complete the construction of the third layer, just in time to exhaust it completely.
In theory, as long as the six-layer Dao Tower is fully constructed, the cultivator can use the foundation, talismans, divine skills, or arrays of the Dao Tower without any preparatory rituals.
However, Owen got the short end of the stick, because he used Congenital Talismans. Even if the Dao Tower is completed, he would only be at the peak of the Third Great Boundary. He does not have enough power to use Congenital Talismans. He can still enjoy the benefits of the Dao Tower Realm, summon talismans with a wave of his hand but can only use reduced-power version of Acquired Talismans.
"Even if it is the weakened version, I believe it's still more powerful than the talismans released by most cultivators at this realm."
