Lex studied the clearing clouds for a while more, even using his left eye but saw no traces of anything unusual. For a second Lex wondered if he had been mistaken, but then immediately dismissed that idea. Let alone the fact that Lex's senses were incredibly sharp, even if he were an ordinary immortal, it would not be so easy to fool his senses, and it would be even more unlikely for him to mistake nothing for something.
That meant that, somehow, Lex had momentarily cut open a path to another place with his sword. He wondered if the key to doing so again was just a random cut, or if he had to cut tribulation clouds.
