Hai Ling quickly retreated a long way before he stopped the aircraft and observed the display.

"This time, there is a twenty-minute gap between the sound waves and when we came!"

Dr. Yuan looked at the monitor and said, "It should be their normal detection, they didn't expect humans to go down to the bottom of the sea to detect them, and they may not have done it before, it wasn't aimed at us!" ”

"Well, what we heard in the past wasn't big fish."

Wang Ke took it and said: "It's their routine detection, it looks like we're really going to find their base, but ······ There is no light at all, and they live in the dark seabed? ”

Except for the light of the aircraft, the bottom of the sea was still terrifyingly dark, nothing could be seen, and there was no light at all, just now Wang Ke thought it was not close.

"That can't be!"

Dr. Yuan shook his head and said, "We must not have found it yet, or they have something to hide, just wait for this sound wave to pass, and we can move on." ”

The sound waves lasted about three minutes or so, and then the monitor calmed down.

"Hailing, go in the direction of emitting sound waves!"

Dr. Yuan then said: "The time for our detection is limited to 20 minutes, that is to say, within 20 minutes, we will find what we can find, and if we can't find it, we will retreat and return to a safe area." ”

"Understood!"

Hai Ling agreed: "Enlightened Doctor, they were detected, probably because the height was not enough, and they were detected by this kind of superinfrasound." ”

Wang Ke pondered that this was also the case, but fortunately, when the three of them came, they found that kind of sound wave, avoided it in time, and reappeared the second time, just on the edge of the infrasound wave detection, and exited in time.

If the three's aircraft is within the range of their detection, it should also be discovered, and there will even be danger, even if it is not dangerous, they know that someone is detecting, which will bring great inconvenience to future detection.

Thinking so in his heart, Hai Ling's control aircraft quickly sneaked and drove to the area in front, and soon saw a glimmer of light.

It is also shocking to say, that ray of light is in the middle of a huge submarine mountain, one of the huge peaks, there seems to be a big cave, it looks extremely huge, black, a large area, slightly bright, very terrifying.

"This should be it!"

Hai Ling asked, "Dr. Yuan, shall we go in?" ”

"Gotta go in!"

Dr. Yuan hesitated for a moment and said, "Go in and have a look, we will come out within twenty minutes as soon as possible, there will be no danger!" ”

Wang Ke also nodded, since he has seen the light, how can he not go in?

Hai Ling was already bold, and immediately controlled the flying machine to fly into this huge hole.

There are also a small amount of fish and shrimp in it, which seems to be glowing with light, but Wang Ke knows that this is not the light on the body of fish and shrimp, there must be another hole in it.

This huge cave is also like a huge crack inside, the light is getting stronger and stronger, and further inside, a shocking scene is presented in front of Wang Ke's three eyes.

It seems to be a huge valley, with no end in sight, and the bottom is all white, or light-colored dome-shaped buildings, and the middle one is huge, and it looks like it is not tens of kilometers in size.

Around this large building, there are divergent, neatly listed all kinds of small dome buildings, although the arrangement is neat, there are also large and small, the large visual diameter is always hundreds of meters, even hundreds of meters, and the diameter of the small is also tens of meters.

These buildings are almost identical to the labs you first see, and they are also opaque, making it impossible to see what is inside.

Around these buildings, there seems to be something wandering around, and because of the distance, I don't know if it's fish or shrimp, or whatever.

That's the light that comes out of these buildings.

Above the city, or rather their gathering place, there were a number of peaks, which were of very strange shapes, and they all protruded from a large piece, and almost the whole place was obscured, and it was a spectacle.

Wang Ke roughly knew, no wonder humans couldn't find it at all, if they didn't dive to the bottom of the ocean and come in from that entrance, it would not be easy to find it on it!

"I really found it!"

Hai Ling was also shocked: "This scale is really not small, it is equivalent to a city, it is bigger than a city, right?" ”

"There should be!"

Dr. Yuan nodded: "This should be the place where they gather, the people under the sea live here, it's really unexpected, it looks like there are a lot of people, let's go inside, but don't get too close, don't be discovered, I think they must have other detection methods, maybe more advanced than us!" ”

When they got here, they didn't need the light of the aircraft, and the sea spirit extinguished all the lights and sneaked forward on the bottom of the sea.

After some distance, they could see very clearly in the monitor, and several people were surprised to find that those things floating around were people!

Undersea people!

After zooming in, you can see very clearly, their bodies are similar to the height of earthlings, maybe taller, their heads are hairless, their eyes are large, their facial features are complete, they are covered with a layer of blue skin, and they seem to have no clothes.

There is a slight resemblance to the human description of the people under the sea, that is, their hands and feet seem to be webbed, connected together.

They don't wander, they swim in different directions.

The way they swim in the water is almost no different from that of fish, and they can't see anyone stretching out their hands and kicking their legs, but they just swing slightly, and their bodies move forward quickly.

Or because of the distance and light, no matter how much I zoom in, I can't see their faces clearly, I just feel very weird.

One of the undersea people had swam to a circular dome and quickly disappeared inside, unable to see if there was a door.

Wang Ke guessed that there must be a door, and they entered through the door.

"Dr. Yuan, they don't have transportation?"

Wang Ke couldn't help but ask, "In the place where they gathered, that's how they swim?" Or do you not need transportation? ”

"I don't think you need transportation!"

Dr. Yuan also stared at the screen: "We have seen their flying machines, it should be in that huge circular building, there may be other small buildings, you see, the distance they swim is not very far, if it is very far, maybe they will use transportation!" ”

The situation is really similar to what Dr. Yuan said, the people under the sea are like a door, shuttling back and forth, and they don't swim too far before entering another circular building.
