Under Tangmo's call, several magic arrays embedded with magic crystals were instantly activated, and the runes emitted a faint silver-white cold light. Then, the light followed the runes from the connected arrays to the main magic array, awakening the huge magic array on the ground.
Magic power first awakened the outer runes of the main magic array, then gradually moved inward, first to the fifth ring, then to the fourth, to the third, the second... Whenever magic power reached the core area of the array, it would make the runes glow with a luminescent cold light, so many densely packed runes emitting light at the same time that it even lit up the entire room for a while.
Eventually, the magic power flowed along the runes to the central core area of the array, and followed the slot all the way to that little metal plate.
