This Looks Familiar Somehow (1)

While climbing the Tower to look for an Earth Fire.

A message from Five Azure Demon King popped up.

ㄴFive Azure Demon King: Hah. Now that we're out in the open, it's really obvious. You're probably at around 4K now, huh?

What was he talking about?

Then the other masters' messages appeared, too.

ㄴTaebaek Sword Lord: I can definitely see your face more clearly now, child.

ㄴTaehyun Zhenren: Indeed, I can see it clearly. Even when I look around, things are hardly blurry at all.

ㄴJade-Cold Ice Empress: It must be thanks to your spiritual sense growing so much when you reached Qi Condensation.

What did they mean?

Were they talking about something I was the only one who didn't know again...
