Back then, a Demonic Root Tree stood at the end of this trial. Cultivators from that era fought for their lives against the others who joined the secret realm expedition in order to claim what they believed was rightfully theirs.
However, the Demonic Root Tree's rewards, the Devil Fruits, were now demoted to small rewards found in the second trial.
Then, what took its place?
The Tower's descent created a unique situation for this secret realm and many like it. Usually, as they remained sealed for many years, they would eventually grow and change and give depth to their unique atmospheres.
The Tower made their circumstances more unique. The 25th Floor was special in that there wasn't any real battle ongoing. Unless Ascenders found themselves in personal disputes, they had no reason to fight.
