In the huge underground hall, the four-hundred-foot-high dome stone wall is inlaid with beads as big as millstones, which illuminate the hall as bright as day. There are passages on both sides of the hall, connecting stone rooms. There is a stone wall on one side in front of the hall, and a water curtain stone door in front of the stone wall. On the other side... it is connected to a stone bridge suspended in the air without any support.

Under the bridge is an abyss that cannot be seen to the bottom.

The stone bridge is very long, and with the innate perfect vision, you can only vaguely see the end.

There is another hall connected over there, and there are two figures vaguely.

On this side of the hall.

A dozen people are divided into several groups, some are sparring, some are playing chess, and some are chatting.

In front of the bridge.
