Tristan

Ning and the rest were brought to a giant room that seemed to be a training hall. In the middle of the hall was a 20 meters long and 10 meters wide metal stage that rose 10 centimeters off the ground.

Ning wondered how this stage even came to be. There was no way someone brought, what was basically a massive metal sheet, all the way up the tower.

Even in pieces that would be an impossible task. 

So the only answer Ning could see was that someone had directly made it on this room.

Ning was sure he couldn't make this thing even if he wanted to right now. Even as an Aether saint, that looked like an impossible task.

An Aether supreme could likely do it, but that would require them to put a massive amount of effort into releasing all the Aether they had.

With how slow their Aether absorption likely was, Ning didn't think this to be true either.
