The third brother appeared in this hot space. It was empty and there was no one here. The last wave of patrolmen had just left.
It was a cylindrical hole that was a hundred meters deep. However, the wall was embedded with bright raw stones, illuminating the entire space. One could vaguely see many patterns twisting behind the stones, as if they were alive.
Below was a circle about a thousand feet in diameter. This circle was engraved with very thick array patterns. These patterns were connected to each other and kept spreading out from the walls, connecting with the entire cylinder space and condensing the majestic temperature inside.
