Outer Space

Alex flew slower than the others, but Silvermist and Grimsight slowed down to fly along with him. Snowleaf went on his own, flying up past him along with the many others around him who flew as well.

The air at this height was pretty much nonexistent but the barrier of the atmosphere still existed, albeit was got weaker around this stage. Then as Alex flew higher and higher it began getting weaker and weaker very quickly until there was nothing left at all.

Then, he was finally in outer space.

Alex felt a force on the inside of his body as the vacuum tried to pull out everything that was within him. It failed miserably to do any of that. Even Saint realm cultivators would be fine with this much force, let alone him, an Immortal.

"What do you think?" Silvermist asked, the voice coming from his mouth instead of his Divine sense. "Interesting, isn't it?"
