"Whew~~~hiss~~~~huh~~~~hiss~~~"

In a sea of light, Charles only heard the sound of his own long breathing.

When he was just on the surface of the sea, he saw a few ordinary marine fish here and there, but the further down they went, the emptier they became, until now there was only suffocating darkness around them.

At this time, Charles felt that the blood in his body was constantly rushing towards his brain, although he was currently using enough oxygen, but he had an inexplicable feeling of lack of oxygen in his heart.

"Whew~" There was a sound of the sea swinging next to him, and a hazy fluorescence suddenly lit up in the dark sea, which was the light source brought by Feuerbach, who was riding on the back of a shark and was dancing to Charles.

"The water is 100 meters deep, and it's dangerous below!

Charles shook his head to indicate that he knew, and gestured to continue, he had to go down there today.

Looking at the determined captain in front of him, Feuerbach swallowed with difficulty and patted his hand on the back of the shark beneath him.

The red shark's swinging crescent-shaped tail fin led the two of them to continue to dive underwater.

The water pressure in the sea continues to rise. Charles could even feel the creaking sound of the two glass lenses in front of him.

His heart couldn't help but get nervous, if the glass shattered at this time, the strong water pressure would definitely mix with the glass slag and spray directly on his face.

Ten meters, twenty meters, thirty meters, just when Charles felt that his leather clothes were almost at the limit of his endurance, he finally saw the bottom of the sea.

Directly below them is an airport. An airport slanted at 30 degrees, with a flat runway covered in various underwater coral barnacles, Charles would have barely recognized the usefulness of the place if it weren't for the wrecked planes stuck in the ocean floor.

Charles used the flag to stop Feuerbach, who was about to swim towards the plane.

There was nothing he wanted at the airport, neither the exit information nor the 319 relics could be in such a place.

Like modern buildings, the airport is lined with a straight lane for transporting passengers on airplanes, though the lane is so decaying that it is almost unrecognizable.

According to Charles's modern experience, the end of the street should be the center of the island, where what he needs is most likely to be.

Led by a small group of red sharks, the two of them swam quickly.

Swimming in pitch black water at such depths was not a pleasant thing, and the toes of Charles's two feet were no longer frozen, and he estimated that the temperature was close to freezing.

But the good news is that at least so far, he doesn't see anything dangerous, it's a barren place, and he doesn't see anything alive at the moment.

Walking along the runway, various buildings began to appear around the area.

At first, it was just a few single-storey buildings, a bit like a rural village, but gradually there were more and more buildings around it and they became taller and higher, and eventually high-rise buildings up to 100 meters high.

The skybridges between the buildings give the sunken island a touch of sci-fi.

Although these buildings have been decayed to the point of decay, just looking at the specifications shows how advanced and glorious the former main island of the Foundation was.

Charles clenched his fist in one hand to signal Feuerbach to stop, and he swam toward a square platform on the overpass, where there was a map of the main island marked with lines that appeared to be some kind of public transport stop sign.

He quickly searched the map, trying to find a place to store the relics.

"The first two places I found to store relics were in the third or second laboratory, so the place where the 319 relics were stored should be the first laboratory. Charles thought to himself.

Suddenly, Charles's heart tightened inexplicably, and the feeling of being spied on appeared again, and the thing followed, looking at the edge of a tall building in the distance.

Charles didn't make a sudden move, he casually swam up to Faebach's sharks and waved his hand to signal them to move on.

As the two continued to swim forward, Charles placed his finger on the left side of his body and made a quick gesture.

Feuerbach nodded slightly, very tacitly, and he opened his mouth to shout something silently.

Soon, the sharks around him quickly dispersed, and the two continued to swim slowly in the silent island of the sunken earth.

When that feeling returned, Charles began to tap his fingers on the back of the shark beneath him.

"Brake!" The shark that had just left instantly emerged from the darkness around it, opened its hideous mouth, and rushed towards the darkness on the left.

Charles and Feuerbach followed, rushing in that direction, their pupils shrinking as they turned the corner along the towering building.

A huge black hole twenty meters directly appeared in front of them, and at that moment, Charles felt trembling all over, as if he was being targeted by a god again.

After a full three seconds, Charles's paused breathing reconnected.

It wasn't the eyes of a god, it was the eye hole of some kind of underwater creature, its eerie skeleton no smaller than the surrounding buildings.

Looking at the giant skeleton in front of him, Charles could hardly imagine how big this thing was when it was alive, just standing next to it made people instinctively couldn't help but hold their breath.

The water swayed, and the shark that had just escaped came out of the black hole and swung around Feuerbach's fins.

"Didn't find it!"

Looking at the flag in Feuerbach's hand, Charles's face showed a trace of irritability, that thing is gone again, what the hell is it going to do??

He waved his hand and walked towards the site of the viaduct. Since that thing wants to follow, then follow it, he can't waste time now, he must find out 319.

Just as Feuerbach was leaving with the shark, seven or eight tentacles with a twisted black substance emerged from the black hole.

When those tentacles filled the entire black round hole, the entire skeleton of the creature, which was hundreds of meters high, trembled extremely slightly.

The map of the stops was very shabby, and Charles searched for several stops in a row, and finally put all the traffic stops together.

Quickly scanning over the names of the various sites, Charles skimming over the names that clearly resemble the living quarters, and quickly searching for the lab.

Soon Charles found two of them, the D2 lab and the project lab, both of which were on the edge of the island.

Charles immediately set his sights on the project lab, where 319 was most likely to be.

Just as he was about to leave, he saw Feuerbach leaning over, and this time his face showed a hint of excitement, and he patted his hand on the back of the shark under him, and began to gesture to Charles. "One less!"
