As much as Lex wanted to believe in his own divination ability, and his ability to learn anything including divination, he had a feeling he should stay away from it. The feeling was not from his instincts, but his own analysis based on what little he knew of extremely strong cultivators.
If he could learn divination, no doubt Celestial immortals would have an even easier time. Yet it seemed like, for whatever reason, they did not do so. Lex was certain that the repercussions of looking into the future were far more dangerous than just simple lightning tribulations - especially if one was on a higher level.
After all, no matter what explanation they gave for divination, whether it was reading the flow of destiny, or just calculating probability on a wider scale, the truth was that it was messing with time. If there was one thing Lex had learned, it was that messing with time was a bad idea.
