|“||This man-made forest wasn't just for practicing magic. In order to fulfill the needs of students who aspired to take the path of soldiers, policemen and rescue workers for physical training, the density of all the trees and the ups and downs of the ground were all calculated for usefulness; the ponds, the sandy soil, the running paths and the rest were carefully positioned. Also, various devices and instruments were installed. As a result, it served as a base for activities of more than just clubs that took part in competitions; they shared it with clubs centered purely on outdoor physical activities.||”|
