The Heavenly Lightning Bamboo Tower had one hundred floors. The tower was teeming with undead spirits. Their souls were condensed under the help of the lightning power within. Most of them had low spiritual intelligence.
In the first four floors, there were no Void Refinement Realm undead spirits. Undead spirits of that level would only appear starting from the fifth floor but a majority of them were lightning spirits of the Void Glimpse Stage.
The higher the floor one ascends, the stronger the undead spirits they would face. When one reaches the tenth floor, they would then face lightning spirits of the Void Inquiry Stage!
In other words, Ning Fan would not feel difficulty in the first ten floors. As for the floors beyond, however, it would be difficult and risky for him to move up!
