The Tower of Babel had 99 floors, and one would receive a reward for passing each floor.
As the trial tower for the disciples of the Mohan clan, not just anyone could enter.
Only wizards could enter, or they would be stopped by the formation.
The trial of the Tower of Babel was very simple.
The Mohan clan was a branch of the Wizards, and they were good at the formation of heaven and earth among wizards.
Their disciples and clansmen also focused on cultivating array formations.
Only by breaking the array formation could one obtain the corresponding rewards.
However, there was another requirement to enter the sky tower, and that was that one’s age could not exceed five million years old.
This was a huge threshold.
