He took out a set of protective runes, a standard protection kit he recently purchased from the School's materials store, which could moderately prevent the leakage of spiritual power fluctuations.
According to the instructions, he placed the rune kit in the four corners of the room and lit some special incense sticks containing minute amounts of spirit-stabilizing components to ease any discomfort from the first contact with the Gem Level Meditation Technique.

Accompanied by a faint energy fluctuation, the array activated, emitting a faint blue halo that lightly isolated his area from the outside world.
