As Eren thought about it with a calm mind, he was able to come to a few important conclusions about the Nameless Professor and how his abilities worked.
"That Nameless Professor... Even if he can see anything about the future or treasures, it's only as per the original timeline."
"He most probably can't see the changes brought by me or the other Transmigrators in his world. If he could, he would have told her that the Book was going to be in the Great Demon Sect instead."
"If that's the case, his threat level goes down a little. In the original novel, I should have been dead by now. If he can only see that timeline, I might as well be invisible to his prediction."
The more he thought about it, the more interested he became in his theory. However, he also understood that it was only an assumption at this point.
He couldn't confirm anything without knowing exactly how his powers worked.
