"Fifteen-minute Duel" 

This technology was currently used for entertainment and various other purposes, but college students also had a special holographic simulation device, similar to the full dive VR game in many novels and such. 

It was said that this holographic simulation device was only opened to Estonians and the Estonians used the device to exercise their control over their abilities and to explore many creative ways to use unique abilities. 

There were only a handful of such machines in the academy and each use needed a considerable amount of academy credit. 

For many Eltonians, if they didn't really need the device, they would not pay academy credits to use it. 

This holographic battle arena really made Ainsley a little more interested in the upcoming duel. 

The environment really imitated the real forest and it could be a fantasy forest because there were many plants, trees and flowers with strange shapes.
