Behind the reddish-brown wooden door was a spacious hall that took up every inch of space.
The entire tower wasn't divided into levels. Shang Jianyao—who was standing at the door—could directly see the dome that rose into the sky when he looked up.
Large holes appeared in the surrounding walls, embedded with glass that formed rows of windows. They stretched from bottom to top, all the way to the dome. They were currently reflecting blinking lights that flickered.
In the middle of the hall was a large blob of darkness. Deep in the darkness, countless lights flickered and alternated.
They seeped out of the darkness and shone on the window, turning into light.
At this moment, the darkness was constantly expanding and contracting like a beating heart. Balls of shimmering air spewed out, either crashing into the wall, flying toward the dome, or striking the ground.
