Han Li's eyes immediately sprang open upon hearing this roar, and a surprised look appeared on his face.

With the power of his current spiritual sense, even without intentionally releasing it, he could gauge the situation in a radius of several thousand feet around him as if it were second nature. Furthermore, prior to landing on this island, he had made sure to scan through the surrounding area in a radius of close to 50 kilometers, but was unable to find any demon beasts.

However, now was not the time to consider these things. He immediately unleashed his spiritual sense with all his might toward the seabed around the small island.

The roar had come from directly down below!

Mere moments later, Han Li's expression changed and he suddenly shot forth into the sky as a streak of azure light. He reached an altitude of several thousand feet in the blink of an eye before stopping there, looking down below with a grave expression.

Almost at the exact same moment, gusts of sea wind intermingled with a foul odor were swept up. Countless vortexes of different sizes appeared on the face of the nearby ocean and rows of massive waves, each over 100 feet tall, emerged one after the other. Loud rumbling booms erupted as the gargantuan waves crashed into each other, sending vast amounts of seawater spraying into the air above.

A horrifying doomsday-like...
