at this time.

The submarine's anti-gravity device has been turned on. Lin Feng could not feel the changes in gravity around him. He activated the wave-breaking cone in front of the submarine, allowing it to rotate at high speed, forming a strong vortex around the submarine's body, and then crashed towards the huge pyramid at full speed.

A 'tip slip' sound.

The submarine sprinting with all its might was like a steel needle, piercing through a piece of thin paper, rubbing through the vortex, and then suddenly sank, piercing towards the bottom of the pyramid.

The lights on the dashboard flashed, indicating that the submarine's power system had reached a full load. After several struggles, it was difficult to recover from stability.

Then, there is silence, even quieter than death.

The water flow seemed to be still here, time seemed to be still, and even the lights on the screen stopped moving.

Lin Feng thought he had read it wrong, but after waiting for a long time, the light of the power system went out, which made Lin Feng breathe a sigh of relief.

It turned out that time had not stopped, but the silence around was too terrifying.

In this absolute silence, even my heartbeat was as loud as thunder, and even my breathing was as loud as a train passing by.

The place where Lin Feng stays now is still a distance from the body of the pyramid. This distance is not far away, nor is it close, it is just a distance of more than a dozen submarines.

It's about a few hundred meters.

Lin Feng turned on the engine, but did not rush straight to the pyramid. Instead, he let the submarine slowly swim in this quiet sea.

There was no sun and moon under the water. Lin Feng didn't know how long it had been driving the submarine to swim. He only remembered that he was bored and dozed. After waking up and observing for a while, he drowsed. Only then did the submarine complete a round of gold.

Of course, this is also related to this terrible quiet area of ​​water. The submarine has now used 80% of its energy, but it is not fast at all, as if the submarine itself is also afraid that the sound of the propeller has disturbed the sleeping pyramid.

I saw that at the waist of the pyramid, there was a visible area that was obviously different from the surrounding area. In a flat piece of stone, the gap looked down at the sentient beings under my feet like the eyes of the pyramid.

According to the traditional rules of the pyramid, this should be the entrance.

Lin Feng analyzed the external drawings of the pyramid and drove the submarine to slowly slide towards the entrance.

How many people should be able to live in such a huge city? How much manpower and material resources does such a huge pyramid require? All of this was completed in ancient times.

Ancient times! Is it really far from technology?

No one knows, it's all a mystery.

And now, this mystery may be solved in Lin Feng's hands.

In prehistoric times, the Mayans in South America dug huge stones weighing 2.5 tons and built a magnificent pyramid-style temple. But later generations did not find out what tools they used to complete them.

They don't even have wheels!

How can this be possible to complete an almost "impossible" task of building a pyramid?

How much manpower and material resources did this pyramid take? How many years did it take to be built? All of this is a huge mystery.

Gradually, Lin Feng got closer and closer to the entrance.

When the submarine sailed towards the entrance, Lin Feng unconsciously saw a scene in his mind. It was a sonar scan of the underwater pyramid of Fuxian Lake in China.

It is speculated that the pyramid under the water of Fuxian Lake is as wide as two.4 kilometers.

Different civilizations around the world choose the same pyramid cone to build their tombs?

You should know that it took more than three thousand years to be introduced to China by bronze casting technology. How much time does it take to be introduced to China by pyramid technology?

And what about the pyramid in front of you?

Lin Feng couldn't stop laughing, because here, basically most of the detection equipment has failed. This sleepy water wave seems to be particularly sticky, and the data sent back is chaotic, which requires a lot of computers to spend a lot of time processing calculations.

You should know that when the American American landed on the moon, all the data of Caiji alone was used to look at the largest and fastest computing computer in the world at that time, but even so, it took them thirty-years to clean up the data.

Even though Lin Feng has super powerful super intelligence, he does not expect to complete the calculation of these data within an hour.

The submarine slowly approached the entrance of the pyramid, telling the rotating wave-breaking cone to stop operating.

Now, the submarine is quietly lying on the waters at the entrance of the pyramid, as if it is a shark waiting for an opportunity to move.

But what Lin Feng didn't know was that at this moment, 50% of the submarine's energy was used for communication. The seeds it emitted sowed through the earth's crust and arrived at the intelligence from the ground at a straight line distance.

Then, according to the super intelligent instructions, Lin Feng sent out a series of radio wave signals from the wave-breaking cone.

Silence, or deathly silence.

Lin Feng was really impatient in the silence. He reached out to regain control of the submarine. At this moment, the stone gate of the pyramid quietly opened a crack.

The submarine then drifted into the gate and entered the corridor of the pyramid.

This is a corridor that is unknown how long. As the submarine continues to float forward, Lin Feng feels that something is wrong with the water flow.

He quickly opened the radar at the stern of the boat, and then he found that the door was closed behind him, and the water in the corridor poured in an unknown direction.

The water in the corridor became less and less, and gradually, the dorsal fins of the submarine were exposed.

Fortunately, the propeller part still loves the air, so it does not lose power and is stuck in place.

Soon, another gate was ahead. This time, the submarine seemed to have no pause. The gate quietly opened when the submarine searchlight had just shone. Following the influx of water, the submarine walked into the gate like a fish about to be stranded.

Then, the door gradually closed behind the submarine.

In this way, after passing through the seven gates, the water in the corridor finally became shallower and shallower. In the end, the submarine's propeller had completely escaped from the water surface and lost its power. It was washed away by the water flow and was stranded in the puddle of this ghost place.

At the same time, behind the seventh level gate, the pyramid no longer moves, and the submarine is still.

Lin Feng waited for a while, as if he understood what he should do, so he stood up consciously, checked his guns and weapons, took a flashlight, and prepared to get out of the submarine.
Chapter completed!
