Meeting an Old... Friend? Pupil? Senior...?

Deciding on spending the next few days wandering around the Blue Sea Empire as he waited for the overconfident ancestor from the Blue Sea Empire to at least get into the Frozen Wasteland by the time he made his way back to the sect, Xuan Hao ended up making his way back to the location where the special location contain the Sea of Mist, Ephemeral Forest and the Valley of Illusory Beasts, was located.

Not so much because he planned on entering the place following what had happened the last time around, but more so because he was feeling curious about what had happened since he had left.

Did all the illusory beasts get killed off by the Blue Sea Empire or had some of them survived?

What about the Valley of Illusory Beasts? Was it completely closed off following the desperate and successful escape attempt from the illusory beasts?
