"First, you have to be in the Sword Soul Realm to even attempt it, but those in the Sword Soul Realm probably can't get past the Ninth Layer. The ideal level for the challenge is around the Third Heaven of the Sword Spirit Realm. Cultivators at that stage can likely reach the twentieth floor.
On each floor, the gravitational effects and pressure on one's Soul both increase significantly. If you can reach the twentieth floor, then after breaking through to the Void Realm, your Battle Power will surpass the limits of the Master Level and reach the True Profound Level. In other words, your Battle Power will be at least a four."
Xia Xinqin's beautiful eyes glimmered with a misty light. When she spoke of the Royal Family's Celestial Tower, she was extremely confident.
Her entire being seemed to gain an extra layer of Spiritual quality, and Ye Tianling found himself momentarily captivated.
"The twentieth floor? Princess Xinqin, how many floors have you reached?"
