Moke guided the group through the hall, and they soon entered the basement of the tower after going down a series of steps. The thick walls blocked off the morning sun rays, and the surrounding air was turbid. However, the spooky aura could not shield that intense magical wave. This was the nucleus of the whole tower, and all of the magical devices in the tower were supported by these tightly shut secret rooms.
The engineers that had designed the tower personally comprehended everything here the best. Of course they knew that out of all these secret rooms, there was one meant for providing energy for the tower. To this day, they still remembered that this President Felic had come to the incomplete tower by himself on a night with a clear moon and few stars, and mounted a fiery red magical crystal on the source of mana. After that, the whole tower was surrounded by an enormous magical power.
