"Okay, slow down, slow down......"

Wang Rui stood next to the deep cave and instructed the rest of the people to put the steel cable back on the pulley.

Although the steel cable is broken, fortunately, there is a steel cable that was previously sealed by the former Soviet Union in the building unit on the side, which is shiny and very well preserved. Moreover, after decades, motors and other equipment can actually drive, and I have to sigh that the industry of the former Soviet Union is indeed very strong, how can this solid equipment not make people feel admired.

With these very usable equipment, Chen Yang and the others only need to take out a part of the low-temperature -50# diesel from the snow cruiser and generate electricity, so that the motor can run and drive the steel cable down. This is a complete reproduction of the usefulness of the equipment made in the former Soviet Union.

It's just that although the equipment has been completed, it is another difficult problem to send who to send down next.

Fortunately, Chen Yang brought two specially modified TC-200 drones just in case, which can be applied to this situation.

"OK, let's go!"

The team member who controls the military three-defense computer made an OK gesture, and the person on his own side immediately put the drone on the ground.

The drone that received the command, the red light flashed, the self-test was completed, and it slowly rose from the ground in levitation, and under the precise control command, it came to the top of the deep hole, and then began to descend, slowly suspending towards the deep hole.

The drone's four mounts are equipped with cameras on top of them, and the high-definition real-time footage transmitted back through guò is wireless, so that everyone can see the situation below.

Under the light of the drone, the ice wall reflects a faint blue light, which is beautiful and very beautiful, but everyone's attention is focused on the rest of the place, and they have no intention of enjoying this beautiful scenery.

The diameter of the deep hole is 1.5 meters. Enough for the drone to fly downward, but it is important to note that the deep tunnel is not in a vertical line, and after descending six hundred meters, there is obviously a bend in amplitude, forcing the team member who controls the drone to be more careful.

Ten minutes later. After the barometer mounted on the drone, everyone looked at the screen in surprise, nine hundred and fifty-seven meters!

The depth of this deep hole has reached 957 meters!

Of course, the surprise was only for a moment, and then everyone couldn't help frowning.

After arriving at the bottom of the deep cave, there is no ice around it, replaced by an extremely hard stone wall, but in front of the drone is a stone wall tunnel with as many as three forks!

"Sir......

Look at such a picture. The team member operating the drone looked up, waiting for further instructions.

"Let's go to the middle one."

Chen Yang chose one at random.

"Yes."

Agreeing, the team piloted the drone and flew to the tunnel in the middle.

Who knew that before the drone approached the middle tunnel closely, all of a sudden, the real-time picture transmitted back became blurry, flashed a few times, and the frame rate froze and stopped on the picture just now. There was no more movement.

"What's going on?"

Wang Rui was puzzled.

"Signal...... The signal was interrupted, and the signal transmitted back by the drone could not be received. ”

The team members were surprised.

"Signal outage?"

Chen Yang was a little surprised. "Is it a drone malfunction?"

"No, it's not, it's distracted......"

As long as it is not the fault of the drone itself, after losing the remote control command, it will enter the intelligent judgment mode by itself and react loudly. Before waiting for the team member to further investigate the reason, the signal screen transmitted by the drone appeared on the screen again, and the drone actually retreated!

"This ......"

Everyone was stunned, a little confused about the reason.

"Take a closer look." Chen Yang said suddenly.

"Yes."

The team member reacted and immediately controlled the drone again to get up close and personal with the fork in the road. Unexpectedly, the previous qiē happened again, and the wireless signal was directly interrupted.

And when the drone returned by itself again, the wireless signal was restored.

After such a few similar encounters, everyone understood that as soon as they approached the fork in the road, the wireless signal would be interfered with, and they could no longer transmit real-time images back.

In this way, the role of drones is minimal.

"Bring the drone back...... Shadow! ”

Chen Yang commanded, and then shifted his gaze to the shadow.

There was no need for Chen Yang to say anything, the shadow had already understood what Chen Yang was trying to express, nodded slightly, and when the drone was called, he didn't use the hook of the steel cable to hang on himself, he directly reached out and grabbed the steel cable, and let people put him down.

This kind of long-lasting arm strength, in exchange for the previous shadow, did not dare to take this risk to try, but after the shadow of the aphid parasitism and the change of the body, such a thing is not worth mentioning for him.

He easily reached out and grabbed the steel cable, and someone lowered it from it.

The EMER team member looked at the shadow in a cold sweat, for fear that he would suddenly let go of his hand and let go directly, so he fell from a height of nearly 900 meters, and wanted to ...... It's going to be ugly.

Only Chen Yang had a calm face, and he didn't say anything to stop the shadow's adventurous move, and he didn't seem to worry about any accidents at all. However, the facts also proved that Chen Yang's indifference was not wrong, and after more than ten minutes, a signal from below said that the shadow had arrived safely below.

Others don't dare to be as big as the shadow anymore, and they hook themselves honestly and practically, and after ensuring their own safety, this is what makes people put themselves down.

A total of seventeen people, except for two EMER team members who were left on the ground, the remaining fifteen people all entered the bottom of the deep cavern.

"The temperature is minus thirty-five degrees, the air composition is normal, and no toxic gas components are detected......"

After testing the air and confirming that it was harmless, everyone took off their oxygen masks.

Different from the real-time images transmitted back by the drone, when he really stepped into the ground more than 900 meters deep, the cold and unfamiliar environment, all the elite mercenaries present were not afraid of death, and he also felt a burst of hair in his heart.

It's more than 900 meters below the Antarctic ice, and if something happens, they will never get out.

No one wants to really encounter such a scene.

"Alright, let's get started."

Chen Yang assigned the task, "Shadow, you take four people to the left." Putum, you take five people to the right, Wang Rui, you and the rest of the people go with me. ”

"If you find anything unusual inside, don't risk it, return here immediately and try to contact me...... Remember, you must not take any risks, and don't touch what you don't know, you know? ”

"Yes......"

Everyone was not very clear about Chen Yang's purpose and behavior this time, but in this kind of place that they had never dared to imagine before, the tension in their hearts was extraordinary, and only by touching the gun in their hands could they calm down.

Looking at Shadow and Putem, the two of them led a group of people into the tunnel on the left and right respectively, and Chen Yang walked in front of the first and entered the tunnel in the middle.

Wang Rui took a deep breath, waved his hand, and asked the two team members behind him to follow, and hurriedly followed behind Chen Yang, looking around nervously.

It doesn't have to be that everyone needs to turn on the tactical flashlight, only two people need to turn on the flashlight, and the tunnel with a diameter of three or four meters will be illuminated by the light, and no hair will be visible, as long as there are any unusual items and clues, they will be discovered by Chen Yang immediately. Unfortunately, the stone walls of this tunnel are smooth and tidy, and there is not even a piece of garbage on the ground, so there is nothing unusual at all.

Wait a minute...... If there's anything out of the ordinary, it's this deep tunnel with a stone wall.

What kind of equipment did the former Soviet Union use to dig a tunnel of this length and diameter at such a depth?

You must know that this is Antarctica, and if you want to transport heavy equipment and machines, the energy and cost are huge, and even the Soviet Union cannot do such a meaningless thing without moderation.

Chen Yang didn't need to speculate too much to be sure that the Soviets must have some ulterior motive in making this kind of tunnel here.

So what is the ulterior motive that seems to be related to the change of the cube......

This qiē made Chen Yang very curious.

The length of the stone wall tunnel should be more than 100 meters, and after several laps in a row, Chen Yang suddenly stopped, raised his head and looked at it, and was stunned.

This style of painting...... That's not right!

This is Antarctica, how can such a thing happen?

At the end of the stone wall tunnel, a stone door with a height of three meters suddenly appeared...... It was indeed a stone door, and the obvious traces of artificial carving were clearly left on the stone door under the illumination of the light.

“……”

Chen Yang was stunned for a while, and before Wang Rui and the others could react, he walked to the edge of the stone gate, picked up a tactical flashlight and shone it up.

The distance is closer, and you can clearly see the signs of carving on the stone door, which has never seen the pattern pattern before, from top to bottom, covering the entire stone door, and where the pattern is not carved, it is smooth and smooth, without the slightest trace of axe and chisel carving, just like the contemporary machine qì deliberately polished.

In the underground of Antarctica, it was surprising that the Soviets drilled a deep hole, and no one thought that at the bottom of this deep hole, there was actually a beautifully carved stone door, which was completely unexpected by Chen Yang.

"Granite ......"

Stretching out his hand to stroke the stone door, Chen Yang fell into deep thought for a while. Granite is not uncommon in Antarctica, at least in Queen Maud's land, there is a mountain system of granite and sedimentary rocks, and the rock walls here are also composed of some granite.

But how on earth did this stone door get here?

Who built it?

Look at this ancient appearance, it doesn't look like it was made by the Soviets...... What's more, the Soviets didn't panic so idly and make such a ghost thing out of the ground. (To be continued......)
