1150 World Chapter

The longer they existed, the greater the size of the small planes, and the bigger they were, the harder it was to find the special location.

This was due to the fact that the duration of their existence had nothing to do with their size.

Unless Lin Yun gave up looking for the Augment and directly returned to the Raging Flame Plane, he had to leave each small plane before its destruction.

But sometimes, a small plane he stepped in would already be on the brink of destruction and he would only have a couple seconds to look for the abnormality. 

Lin Yun ended up leaving a small plane just as it was destroyed four times.

Lin Yun's mana was supported by the Natural Demiplane, so he wasn't too worried about continuously travelling back and forth a few dozen times, but it was extremely taxing on his mind, which was reaching its limits. His soul was also exhausted.
