As soon as the captain gave the order, the fish took their positions.

Since the search is aimless, the speed doesn't need to be too fast. The fish in the sea only need to stay in the sea and move forward with the Future.

Of all the crew members on the ship, Ai Si had the strongest mental power and the widest detection range, so Gu Xi made him the fish-shaped detector.

Let him discover something different in the sea, and then tell her.

Gu Xi slipped into her room to continue training her mental strength.

And so, the Future sailed slowly at sea for two or three days.

At first, those scattered little dark clouds on the horizon began to slowly move toward the sky above.

They spread silently, covering the sky. Gradually, the speed increased, and the dark clouds rushed in from all directions, merging and devouring each other, the black area constantly expanding.

The dark clouds continued to gather, layer upon layer, piling up thicker and thicker, until the entire sky was completely dark, as if a huge black iron pot had been turned upside down, oppressive and gloomy.

Ignoring the pitch-black sky, Ai Si stood quietly on the third-floor observation deck, his gaze casually sweeping towards the distant seabed.

As he scanned the area, he noticed something unusual, as if something was present there.

His gaze focused on the past and he saw a faint glimmer of light.

Ais immediately mobilized his mental energy to investigate, but when he extended his mental energy, he was unable to detect the light.

It's visible to the naked eye, but impossible to detect with mental power?!

Ais widened her eyes slightly, a hint of surprise in her eyes.

He intensified his mental output again, focusing all his attention on sensing, but still gained nothing.

Ais was astonished. When did his mental strength become so weak that he was completely helpless against this light?

Gu Xi took small steps and walked up to the small garden on the third floor.

She noticed that Ais's expression was somewhat strange and became extremely curious.

"Ais, what's wrong? Did you find something?"

Ai Si calmed down from her shock, then pointed to the glowing spot and said slowly, "Puru~ Look over there, that place is very strange, my spiritual power can't detect it."

After hearing this, Gu Xi looked in the direction Ai Si pointed out, and sure enough, there was a faint light there. If it were daytime, this light would definitely not be noticeable at all.

Suppressing her shock, she focused her mental energy and peered in that direction.

Wherever his spiritual power passed, every detail on and under the sea was clearly visible, except for that ball of light, which seemed to be invisible.

After trying it, she stared wide-eyed in surprise.

"This is really strange, what on earth is going on?!"

The man and the fish exchanged a glance, both seeing confusion in each other's eyes.

Gu Xi acted decisively, using his mental power to send a command to the octopus, instructing it to steer the boat toward the light.

Upon receiving the message, the octopus immediately began to accelerate.

The Future ship shuddered slightly, then headed straight toward the light.

A short time later, the Future arrived at the area around the light.

The unknown always makes people uneasy. For safety reasons, Gu Xi left Yan Lin on the ship while he took Ai Si and flew towards the light cluster.

At the point of light, Gu Xi stood on the spikes, hovering in the air, his gaze eagerly searching downwards.

However, the light seemed to be shrouded in a huge black curtain; apart from knowing that it was light, nothing else could be seen.

Gu Xi frowned, then turned to Ai Si and said, "Ai Si, freeze the seawater 300 meters below this ball of light."

Ais nodded, a flash of blue light in her eyes, and her burgeoning spiritual power spread towards the seawater below.
