"The Dragon God Tower is the divine weapon protecting our Dragon God Empire. Legend goes that it's the supreme divine weapon that His Holiness, the great Dragon God, forged for the Dragon God Empire after he had deified."
The Fighting Dragon Academy president explained smilingly, "The Dragon God Tower is sited inside Dragon God Academy. It has a total of 100 levels, and each level is an independent half-plane of existence."
"A half-plane?"
"Yes, a half-plane!
"The magic elements in these half-planes are extremely rich and dense, and even the laws of nature inside are much clearer than the outside world. You can achieve more with less by cultivating inside these half-planes. They are excellent cultivation spots.
"This has led to hordes of people desiring to enter the Dragon God Tower to cultivate. Unfortunately, only those below 30 years of age and stronger than eighth-grade are qualified to enter."
