Chapter 752

Human beings have an instinctive resistance to darkness.

It's nature, deep in human genes

Thirty minutes later, a few starlike blue spots appeared in the darkness.

The destination has arrived.

The strange sound above also attracted the attention of the exploration team on the platform.

When they look up, with the help of night vision, they see the figure of the road is sliding.

It's Sergeant Vanya with backup.

Seeing this scene, the exploration team on the platform was relieved.

Darkness makes people nervous, and they will feel a depressing atmosphere. With the increase of the same kind, the pressure will be reduced.

Human beings are gregarious creatures, and the power of groups is endless, which can also bring people self-confidence.

"Bang! Bang

In a sound of impact, the backup forces one by one landed on the platform.

With the arrival of the backup forces, the huge platform suddenly became lively.

In the dark, the figure is shaking, and the blue light is flashing.

That's the light from the sensors on the mobiles' helmets.

"Welcome, chief Vanya!"

As soon as he stepped on the platform, a mobilized soldier met Vanya.

Looking around, the huge platform came into Vanya's eyes.

On the screen in the helmet, the capture program is distinguishing what it is looking at.

Rocks, rising light green gas, and mobilizers moving on the platform.

Looking back at the mobilized soldiers in front of him from a distance, Vanya said, "I've brought four sets of sliding rope equipment. Install them immediately. Before the backup equipment arrives, we must find out how deep the sinkhole is!"

"Yes

At Vanya's command, the troops who had just arrived immediately took action.

Every few people carry a sliding rope equipment to the edge of the platform for installation.

In the dark, the mobilizers were moving, and the blue light was flashing.

After a "Ding Ding" sound, the sliding rope device is fixed at the edge of the platform.

The light green gas rose slowly in front of him and stood at the edge of the platform. Vanya looked at the end of the line of sight below the platform.

Darkness, the end of the line of sight is a deep darkness.

Looking at Vanya, he took his eyes back. Looking at the mobilized soldiers on the back of the sliding rope on the edge of the platform, Vanya nodded and said, "let's go! Put down the rope

In silence, the mobilizers began to move.

Pick up one end of the rope and throw it out of the platform.

In the sound of "shuttle" rotation, the sliding rope equipment is trembling, and the rope is rapidly released.

The green indicator light on the sliding rope equipment, flashing rhythmically, reminds people that the equipment is running.

The voice of "shuttle" has been ringing all the time, and the mobilized soldiers have concentrated on the edge of the platform, watching the running sliding rope equipment, waiting patiently.

ten minutes later!

"It's 2000 meters!"

In the dark, the sound reverberated, which did not break the tranquility of the platform, but there was an indescribable and unidentified atmosphere, which was tense and surprised.

"Three thousand meters!"

"Four thousand meters!"

With the report again and again, the atmosphere on the platform has been compressed to the extreme.

"Five thousand meters!"

"Six kilometers!"

With the words of six kilometers just falling, in the numbness of the mobilized soldiers, the sliding rope equipment suddenly flashed a red warning.

Red alert?

"It has arrived, more than 6200 meters in total. The red indicator light flashes, indicating that there should be water at the bottom of the sinkhole."

With these words, all the mobilized soldiers on the platform were relieved.

Finally, if it continues, they even doubt whether the crater will pass directly through the mantle.

Although at this depth, there is still a long way to go from the mantle.

But more than 10000 meters deep, it can be said that this is beyond the scope of human beings.

Fortunately, their first regiment has advanced equipment, closed power combat suit and additional oxygen tank. As long as the underground temperature does not exceed the limit that power combat suit can bear, there is no problem in underground space activities under 10000 meters.

More than 10000 meters?

To calculate the depth of the sinkhole, Vanya said to himself.

He had never seen such a deep sinkhole.

There are also pollution animals. No passage was found in the cliff all the way down. This shows that the pollution animals come from the bottom of the sinkhole. How do these pollution animals survive under the condition of lack of oxygen?

Oxygen?

Think of this, Vanya a Leng, hurriedly detect the indicators in the air.

After a while of detection, the detection indicators are displayed on the screen.

The temperature is right. The current temperature is 23 ℃.

The amount of oxygen is moderate, a few zeros less than that on the ground, which can be ignored.

It is reasonable to say that 5000 meters below the ground, the amount of oxygen is already very scarce.

But it doesn't make any difference.

There is only one possibility, that is, there is oxygen at the bottom of Tiankeng, otherwise it can't explain this situation.

I didn't think much about it. Now Vanya knows very well that any guess is superfluous. As long as I investigate it myself, all the mysteries will be revealed.

Vanya gave the order.

"The first and second teams are ready to follow me on the exploration mission. Remember, we must check whether the power is sufficient and prepare more reserve batteries. It's easy to go down, but it's difficult to come up. Once the power is exhausted, you will be unable to move in an inch!"

"Yes

"Yes

Two voices responded one after another.

Then, two people's words rang out in the dark.

"Team one! Get ready to go

"Second team, get ready and get ready to go!"

There was another riot on the platform at the command.

The mobilized soldiers for the exploration mission concentrated on the edge of the platform and the location of the sliding rope equipment.

"Sergeant! It's ready! "

When they were ready, the team leaders reported to Vanya.
