1202 Invitation from Swordmaster

It was a cooling night.

Within an underground palace that was originally huge, the insides had been enlarged to an even wider space using void arrays.

The palace had a total of six levels.

The top three levels were where the palace master and his disciples stayed.

The bottom three levels were places for experiments.

Currently at the lowest level, it was a dark place. The ground glowed in crimson color, and a bloody aura permeated the place.

"The experimental materials have all been gathered." The eyes of the black-robed palace master were filled with excitement. He took out a jade bottle. Following that, he uncorked it, causing many human figures to fly out. Many cultivators were brought out of the bottle, and they were currently looking around them restlessly.

The dark place, the crimson floor and the bloody atmosphere.

Those factors made them even more disturbed.
