Chapitre 98: Blink.

Behind many-dimensional doors and past corridors that were protected by different traps, arrays, and defense mechanisms, there was a room lit up by a large Thranium crystal at the center of the room.

(AN: In chapter 16 (The Azeroth war I mentioned the thranium age and what a thranium crystal is, so check it out if you have forgotten.)

The pink crystal was twice the height of a man and its width was greater than that of two men standing side by side. The huge thranium crystal was floating at the center of an array that powered the entire facility, if one took a closer look at the crystal, one would be able to notice the cracks that had formed on the crystal.

If someone was here, they would have been able to notice the energy leaking from the crystals and if that someone was Blake he would have been tempted to cultivate in the room because the amount of energy in the room would put that of the cultivation rooms at the school to shame.
