A melodious horn sounded from Permafrost Island, prompting the teams resting on the ice lake to quickly pack up their camps.

"Kai, every guild sounds the horn three times when they're about to engage a king-level BOSS. This is the first one, meaning they'll start the battle in half an hour!" Hu Yan patiently explained the rules to Jiang Kai.

The guy who claimed to be "never weaker than others" was also awakened by the horn. He rubbed his eyes, got up, and silently began packing up the camp.

Jiang Kai couldn't help but smile, thinking it was amusing that the guy still remembered their mission after a night's sleep.
