Gu Xi can levitate in the air by stepping on the spikes. When Ai Si is not in the water, she uses her talent to freeze the surface of the sea and walk directly on it.

If you only need to find out what is emitting blue light, you can usually just use your mental energy to investigate.

However, when Ais used her mental energy to investigate, she could only detect a large amount of blue luminous matter, but could not see any details. In this respect, these things have extremely strong mental resistance.

A person and a fish stopped 100 meters away from the blue light area.

"Plop~ I'll freeze part of the sea first, then we'll go check it out."

Upon receiving Ais's words, Gu Xi stepped on the spikes and rose slightly into the air, making it easier for Ais to unleash her talent.

Ais was walking on ice, an ice belt that stretched from the Future to his feet.

He crouched down and gently touched the surface of the sea with his fingers. A wide-ranging wave of mental energy instantly covered the surface, followed by a chilling aura spreading across it.

The point of contact, as light as a dragonfly skimming the water, acted like a super-cooler, rapidly freezing a thick layer of ice around it. The ice then spread outwards at an extremely fast speed.

The blue waves were crashing toward the area covered by mental energy, as if suddenly frozen in time. The crests of the waves, still surging forward, turned into ice sculptures.

The blue light that turned into ice sculptures did not extinguish its brilliance; the light simply shifted from the waves to the uneven ice surface.

The sea was frozen solid in an instant.

Ais's body didn't sway at all, his expression didn't change, and his breathing remained steady and slow. It was as if the mental energy he had just released was a negligible expenditure for him, as easy and simple as drinking a sip of water.

Seeing this, Gu Xi mentally scoffed. Using mental energy like it's free, this is definitely a sea monster fish that's lived for who knows how long.

However, today she witnessed only the tip of the iceberg of SSS-level mental power. She now seems to understand why SSS-level mental power is so rare in this world.

Even if it's just some mediocre skill, having that ability is still a deterrent. And Ais is usually able to help, so thinking about it, she's incredibly lucky to have found this fish.

"Puff puff~ Let's go!"

Ais withdrew her hand and stood up.

Upon hearing this, Gu Xi landed and jogged towards the blue glowing substance.

Suddenly, Ais stopped and said to her, "Puru! You should be careful too!"

Gu Xi turned to look at him, puzzled.

"Plop! This thing interferes with mental energy. The octopus and the others were affected quickly, mostly because their mental energy was lower. Although you are better than them, you still need to be careful."

Ai Si rarely spoke so much, but it was just to remind her.

"Yes, I'll be more careful."

The man and the fish silently probed for information.

As Gu Xi approached the waves, she discovered that the crests were made up of frozen, blocky objects. They were hidden beneath the ice, with only a small portion of them visible above the surface.

We need to take this out and examine it!

Gu Xi made a quick judgment, then summoned the spikes and smashed one end down with force. The broken ice surface shattered into pieces, and fragments rolled out from within.

Although it emerged, it was incomplete, and Gu Xi poked it back and forth with the spikes.

"This thing looks like a glowing stone!"

"Plop~ It's not a rock." Not far away, Ais pointed to the crest of the wave and emitted spiritual power, and in the blink of an eye, she completely extracted the block frozen in the wave.
