The appearance of the Seer made Chen Yu vigilant.
Although the ability to predict the future is very rare, even in the Multiverse, there are very few people who understand Prophecy Magic and can glimpse future destiny paths, but that doesn't mean none exist.
Before this, Chen Yu did not pay much attention to guarding against Prophecy Magic since, when he was weak, he was not powerful enough to guard against being prophesied.
However, after he became a Demigod, the divinity of a Demigod was enough to ensure that those weaker than him could not predict his fate.
Yet this time, Chen Yu found himself prophesied because what Cooper predicted was not Chen Yu's fate, but his own.
It's like seeing a beautiful lady on the street. If you stare directly at her, she will definitely notice, but if you just glance with the corner of your eye or use a reflection, she might not realize you're looking at her.
