Chapter 1372

The situation at that time was rather critical.

There are only three choices left for fan Tong.

One is to use flesh and blood to fight against the collapsing rock strata, the other is to climb a pit of more than 20 meters in five seconds

Or, cut the rope and fall.

It took him only a second to make a decision, and he decisively untied the lock on his waist.

In fact, his judgment is very correct.

The closed rock wall didn't leave him as long as five seconds at all. He calculated three seconds at most before and after. The solid rock strata hit each other and cut off the light from the top of the head

However, at that time, that was the best decision.

But after only half an hour, fan Tong regretted it.

The situation I am facing now, apart from being able to leave a whole body, seems no better than being crushed on the rope. He had been walking for nearly half an hour, and the cave seemed to have no end, so people could not see the hope.

"Fuck It's like a maze. "

Sure enough, I should have been more secure at that time, but now it's useless to say these things.

There was a slight tremor from the ground.

It was estimated that the place where he had fallen was buried by the collapsed rock wall. Fan took a deep breath and calmed himself as much as possible.

In order to make his mood less depressed, he tried to persuade himself that it was only a scientific research activity.

"Silty quartzite It's not hematite. I didn't expect to find such interesting things here. "

" what's this? Bioclastic rock? "

This is a wonderful discovery.

The frustration in his eyes was gradually replaced by a touch of excitement. With the multifunctional shovel in his hand, fan Tong carefully knocked a bit of rock debris down without damaging the rock mass.

Looking at the baby in the sample bag, the excitement in his eyes became stronger and stronger.

“…… If only half-life testing could be done here, so that I can determine the formation age of the sedimentary layer in this area. "

If the current situation is not optimistic, and there is only continuous noise in the communicator, he really wants to share this happiness with other researchers in the base.

Having collected the tools and samples, he began to move on along the cave.

Although doing these things does not increase the probability of his survival, at least In case of his death, these valuable research materials will become a valuable research heritage.

Of course, if someone can collect his body

The road ahead is becoming more and more difficult.

Sometimes he had to go in and out several times to find the real entrance.

During this period, he had a rest on the road, ate some liquid food, and looked at the few supplies left. Fan Tong's mood was depressed.

But interestingly, he noticed a very interesting phenomenon along the way. The core of Mars is supposed to have cooled, but as it moves deeper into the channel, the temperature around it has risen by about five.

Although the surrounding environment is still very cold, at least it brings a little comfort.

After recording these fragmentary discoveries, fan Tong, who had a little rest, got up and went on.

The passage in front is getting narrower and even harder to get through.

Just as he began to doubt whether he had gone wrong, a pit about five steps wide suddenly appeared in front of him.

Laser ranging shows that the depth below should be about 10 to 20 meters, which is exactly the same as what he encountered just now.

At the edge of the pit, fan Tong stopped and a hard color appeared on his face.

What to do?

Do you want to go down or stay back and find another way out?

If you keep going down, your position may be deeper and deeper, and the hope that someone will collect the body for you will be even less.

However, even if we don't grope down, it's not realistic to expect people on the other side of the base to dig themselves out of the ground more than 20 meters deep with limited conditions.

He could not help feeling a bit of scalp numbness when he thought of the fork roads he had passed before.

Thinking that the situation could not be worse than now anyway, he finally made a decision by biting his teeth. With a horizontal heart and the help of his multi-functional spade, he bravely slid down to the pit in front of him.

Slide down a nearly vertical path.

This time his feet touched the ground, but it was more unexpected than before to meet a lot.

Maybe

Is this the real "bottom"?

At the moment when fan Tong thought about it and stood up to look ahead, the whole person suddenly seemed to be stupid and stunned.

It took him a long time to digest the shock in his heart and slowly squeeze a word out of his lips."Trough!"

"Here Special It's a blockhouse! "

Red and brown stone steles about two meters high stand on both sides of the corridor, just like the stone columns in the corridor, connecting the ceiling and the ground. The complex pattern is exposed on the surface of the stone tablet. Although it is not clear that its original surface is full, a trace of carving can still be seen from it.

All that is before us can no longer be explained by simple geology.

No matter from which point of view, it is not natural.

They are like works of art

A collection of works of art in ancient ruins

Muttering excitedly to himself, fan Tong points the flashlight and the camera on his helmet at the row of cultural relics like sculptures and presses the shutter madly.

If it wasn't for no signal, he would like to report everything he saw here to the base.

All the previous discoveries along the way were not equal to what he found here.

There are traces of civilization in the underground of Mars!

At least ever!

Human civilization is not the only one in the universe!

They are not alone!

He could almost imagine what a sensation the news would cause on earth if it were made public. The excitement of finding the treasure made him almost want to shout out.

"The material, like the sand outside, has basically been weathered into hematite!"

"The totem of Martian civilization? Or something to hold a religious ceremony? Or some kind of handicraft... "

"Wait..."

There was a little light in his mouth. When he fumbled for a stone tablet with relatively high degree of damage and tried to knock off the oxide layer on the surface with the multi-functional shovel, he found that the whole stone tablet was not completely composed of hematite as he imagined.

Even on the contrary

The materials included are calcium carbonate minerals that contain almost no iron.

"Calcium carbonate minerals No, it should be some kind of biomass fossil, and the age of its formation is probably very long. It looks older than the trilobite fossil on the earth. "

Muttering to himself, fan Tong carefully sampled five equal sized rock particles from the inside and put them into the sample bag for preservation.

“…… I didn't expect to be a guest archaeologist one day. "

It's hematite on the outside and biomass fossils on the inside. Back to the time before complete weathering, he concluded that the shell of this thing should be some kind of iron-based alloy material, like a coffin, to seal some living things inside.

Intuition told him that this might be a place like a cemetery.

While there are other understandings, there is no doubt that this is the most likely one.

After tightening the multi-functional spade in his hand, fan Tong continued to move forward along the corridor with the ominous breath. Although the guy in his hand can't bring him more security, it's better than nothing.

Contrary to what he had encountered before, the road ahead suddenly widened as he continued to move deeper into the corridor.

Especially when he stepped into a spacious "main hall", there was a feeling of suddenly opening up.

However, just as he was about to move on, he was surprised to find that his knees could not move forward as if they were against an invisible wall.

As he fumbled in confusion on the invisible wall in front of him, a strange scene suddenly happened.

The sign of the signal displayed on the wrist computer suddenly changed from a cross to a full cell.

Slightly stupefied, noticed the flashing signal light, fan Tong subconsciously restarted the communication module.

A series of noisy electric current sounds soon came from the communication channel.

Just as he looked at the signal on the wrist computer disappointed and estimated that it was some kind of natural electromagnetic wave, a intermittent sound suddenly sounded from his ear without warning.

"Cough."

“…… Can you hear me? "
