Chapter 131: Thirteenth Floor

"Participant Thor has conquered the Twelfth Floor with an SSSS rating, granting all humans in the Tower of Truth the buff [Speed Conquer]!"

"Limited-time buff [Rapid Attack]: +30% attack speed for all humans in the Tower of Truth, lasts 6 hours!"

"Limited-time buff [Robust Physique]: Upon death, humans in the Tower of Truth will not enter a weakened state when returning to the Core City of Truth, lasts 6 hours!"

"Limited-time buff [Experience Ascension]: Merges all previous Experience Boost buffs, +60% experience gain, lasts 3 hours!"

"[Speed Conquer]: Within the first 45 minutes of entering a level, Exploration Rate efficiency +15%, lasts 90 minutes."

As the reward for conquering the Twelfth Floor, [Experience Ascension] directly merged previous experience buffs, providing a higher bonus. It's hard to calculate whether this is a net gain or loss.
