The two-meter-diameter bubbling aircraft travels in the opposite direction along the undercurrent of the seabed.

After three months of tracking, Bailan inferred from a large amount of data and came to a conclusion that this undersea undercurrent, like countless death vortices on the continent, was probably caused by some kind of extremely terrible after an ancient war of destruction. Traces left by catastrophic weapons.

It's just obvious that the weapon that left this violent undercurrent should be a biological civilization developed based on the ocean.

There are many similar undercurrents in the ocean, and anthropologists have discovered hundreds of them with detailed records.

But like this ocean current, which stretches for hundreds of millions of kilometers across the bottom of the ocean and is estimated to have exceeded two star screen units in white and blue, it still seems to have no end, but it is quite rare.

After all, if calculated on the basis of the equivalent death vortex destruction weapon scale, this is almost equivalent to a super death vortex covering the entire principality at one time. Even in the boundless death desert, this super vortex is probably quite rare, at least for scholars. The information contained in the road markings has never appeared before. .

"It seems that at least for a certain period of time in this ocean, a super powerful civilization was born, which is a higher civilization far surpassing the current stage of human academia."

Bailan derived a conclusion from a large amount of data that made her cool behind her back.

The more she devoted herself to this racial war mission, the more she felt that she was not fighting alone, but representing the will of a civilization, and she was standing on the basis of a civilization of science, technology, and technology. The pinnacle of consciousness and productivity, groping in the darkness, carefully facing every unknown creature and enemy that he comes into contact with.

And the result of my own thoughts is likely to be the complete destruction of a human-like civilized species in thousands of years...or the extinction of mankind itself.

Boom boom boom boom!

suddenly.

From the sonar receiving device of the foam vehicle, a signal of a specific frequency was sent, which made the white and blue who had been in a lurking exploration for a long time suddenly alert. Fortunately, the ultra-pure water characteristics of the foam vehicle can provide her near perfection in the depths of the ocean. Is hidden, so she doesn't need to worry too much about being discovered first by other creatures or civilizations under normal circumstances.

The position that the sonar perceives is not far away, probably only a few thousand kilometers away.

This kind of distance is almost negligible for advanced civilized aircraft with curved space-time jumping technology.

Bailan steered the aircraft carefully, even taking his breath as lightly as possible.

The sea and ocean current environment has not changed, and she has not found a trace of civilization.

After sneaking for another distance, she finally discovered a super submarine volcano rising from the bottom of the bottomless trench. The magma in the earth's core conflicted with the sea, but they formed a certain combination and merged with each other. They restrained each other and caused the nearby sea to be like a pan, forming an extremely terrifying death field.

The field is like a huge bubble.

In this area of ​​death, under the high pressure of the seabed, the temperature will rise from a negative degree to a few hundred degrees in a very short time, and it is likely to fall from a few hundred degrees to the bottom of the valley. Such frequent changes will affect any matter and life in the field. In short, it will be a disaster.

White and Blue did not rush closer.

Because through data observation, in this area of ​​death, even for her ultra-pure water vehicle, it is a huge disaster. I am afraid that it will not be long enough to cause irreversible damage to the internal structure, and it is already far away from the stars. In the place of the curtain, once the aircraft is damaged, the crisis and despair she faces will be that she will not be able to return to the anthropologist society in this life. Even if she can survive, she will never see a second human being, living like a beast apart.

How desperate this would be.

But here, the signal of that specific frequency is generated, but it is unusually close again.

After waiting in place for nearly an hourglass time, Bai Lan finally got an accurate conclusion that the signal source was only a dozen kilometers away from here. Such a short distance would be just an instant for the foam aircraft.

As long as you don't stay in this terrible area of ​​death, it shouldn't cause much damage to the aircraft.

Thinking of this, Bai Lan made up his mind.

Her mission is to find all the clues about the tidal civilization, and to lock the coordinates in the unknown darkness as far as possible to this highly potential civilization that may threaten mankind in the future, before this civilization has a technological flyover to increase the level of civilization. , Destroy it.

It is a matter of life and death for an anthropologist, even if she takes risks, she must do her best!

call out.

The moment the foam aircraft breaks into the field of death, the seawater under ultra-high pressure is below the freezing point, and the ultra-pure water of the foam aircraft produces an adaptive structure to resist the influence of the external environment.

But this situation only lasted less than ten seconds.

From below freezing to ultra-high pressure boiling, Baidu's jump was completed in just a few seconds.

Before the adaptive structure of the ultrapure water flying transmitter even had time to change, it suddenly fell back below the freezing point. After repeated times, the white and blue could clearly feel the way, and the ultrapure water protective shell was becoming fragile.

"hiss…"

Even though he had anticipated this situation, Bai Lan felt that he had underestimated the danger he might encounter.

But fortunately, the sonar source is getting closer.

The ultrapure water vehicle passed by.

Almost without a trace, Bai Lan captured the device explored by the sonar source, which is a crystal clear drop-shaped crystal aircraft!

It's fluent, almost without any abruptness, like a perfect work of art.

There is no time for a detailed analysis of this apparently damaged alien civilization aircraft. She must escape this terrifying area that is extremely unsuitable for life before her ultra-pure water aircraft is completely irreversibly damaged.

Drop by drop.

"Hint: Found the structure of the anti-gravity anomaly law."

From the aircraft, the voice of Instructor Lei Luo was heard, which was an early warning device specially installed by the Gran Academy of Natural Sciences for this aircraft.

Through the alarm light curtain, Bai Lan finally understood the reason for the formation of this terrible death field in horror.

This is another unknown and terrifying civilization that used anti-gravity law catastrophic weapons to destroy the crustal structure of the trench, and then created this abrupt super volcano, forming this terrible death domain.

And the reason why this civilization used anti-gravity law weapons to destroy the crustal plates here is probably to intercept the catastrophe of this undersea current, and use law weapons to fight against each other to resist this terrible ocean current.

It is a defense mechanism!

really.

When the white and blue piloted ultra-pure water vehicle broke away from this terrible death field, although the undercurrent still exists, the scale and strength have been significantly reduced by more than one grade.

The environment here is barely able to survive some low-level creatures with strong adaptability.

In this environment, Bailan can finally breathe a sigh of relief and evaluate the damage to the ultra-pure water aircraft, as well as the data of the water drop lens aircraft, which is more than ten meters in length and far exceeds the volume of its own foam aircraft.

Looking back here, the super volcano is like a submarine dam, guarding the safety of a certain civilization.

Di di di di.

Tip: No vital information is detected.

The ultrapure water vehicle conducted an in-depth inspection of the internal structure of this huge lens vehicle.

"It's really like a huge tear. It can maintain its structure in such an extremely harsh environment. It is an incredible substance. The civilization that shaped it must have mastered extremely terrible craftsmanship, but it's a pity... It seems to be dead, and I don’t know how long I have been sinking here before I accidentally explored it."
