Shaped like a cave in a graveyard.

Professor Vernal, squatting next to a square stone, stood up slowly from the ground with his hands on his knees.

Watching Professor Vernal stand up, Schultz, standing beside him, lowered his arms in front of his chest and asked in two steps.

“Any leads? ”

“Of course… the excavation of relics here is of considerable value and can be described as abundant,” with an exciting expression on his face, Professor Vernal looked at Schultz and suddenly threw a question, “Have you heard the legend of a mummy? ”

In the face of this sudden problem, Schultz stunned slightly and gradually hung a misty expression on his face.

“I've heard a little... What's wrong? ”

“The ancient Egyptians believed that a man's soul could be reborn one day after his death, as long as his body was immortalized. Therefore, in order to prevent the corpse from decaying, the Pharaoh kings would, after their death, instruct their servants to empty their organs, dry them and wrap them in salt, spices, ointment, honey and linen to make a millennial mummy. ”

The throat knot moved up and down, and Schultz looked at the square stones and said with an odd expression, "What do you mean… these ‘sarcophaguses’ exist to prevent the decay of the remains? ”

“Of course not," Professor Vernal laughed and continued, "it is obviously the most unwise option to store corpses in oxidizable metal containers for preservation reasons. We assume that billions of years ago, Mars possessed vastly more oxygen resources than Earth - even more abundant - and that the civilization here possessed the technology to dig such vast works at the bottom of the ocean a few kilometres deep, that they could not have known such fundamental chemical principles. ”

“What do you think this place will be? ”

“Obviously, this is a refuge. ”

“Shelter? ”

“Yes," he nodded, looking at Schultz with satisfaction on his face, continuing, "they sealed themselves in these iron coffins at a time of irreversible disaster on Mars… at least billions of years ago, then dormant with special technology, waiting to wake up one day. As you've probably heard, the frozen dormant technology that's popular on Earth today, the X-0172 bacteria that the Americans seem to bring back from Mars. ”

Schultz nodded and a sudden look appeared on his face.

Of course he wouldn't have never heard of it, and he even remembered what dormant bacteria was causing a lot of wind waves back then.

But now, X-0172 bacteria have gone from flood beasts to fragrances in people's eyes.

Especially for those suffering from terminal illness, it is a gospel. In cases where current medical techniques are not enough to cure them, they have one more option that must be separated from the flesh and blood, but at least can survive...

Schultz, however, is still a little confused.

If these things are dormant compartments, why did they end up in the dust of history?

“Obviously, they failed," Professor Vernal shrugged his shoulder as if he had guessed what Schultz was thinking, continuing, "despite some attempts at self-salvation, their extinction was almost doomed, centuries-old dormancy in front of hundreds of millions of long rivers, but just a dying struggle. The home planet has lost its magnetic field protection, its atmosphere, even its oceans… even a redeveloped civilization needs the soil to survive. ”

Schultz was silent for a while in the face of the unimaginable catastrophe of the end.

A long time later, he asked.

“What do you think these Martians might be? I mean biologically. ”

“I don't know, but mammals can be excluded first, the gravitational environment here is not prone to skeletal development and calcium accumulation, even if mammals are present in the ecosystem here, they should not be large enough to develop skulls wide enough… In contrast, invertebrates should be more advantageous, especially arthropods, and they will be larger in size than the planet, theoretically capable of having larger brains to hold more neurons. ”

“Civilization is marked by fire and the use of tools, but essentially by the ability to process and exchange information. ”

Speaking of which, Professor Vernal shrugged his shoulders and smiled.

“Of course, all this is mere speculation, and even with all the prerequisites, the birth of civilization is full of coincidences. It is only from the samples of ants and bees that it is possible for arthropods to evolve social systems that coordinate large populations and engage in more intensive productive activities. ”

The color of excitement on Professor Vernal's face grew stronger.

Closed eyes looked around, as if sitting in front of him at this moment was not a pile of rocks, but a gold mine!

“… everything here is very interesting, it's like a pyramid of Mars civilization, and by excavating them, we may be able to restore the cause of Mars' loss of magnetic fields, and what other attempts at salvation have been made by the people of Mars living here at the last moment of their lives. These precious monuments have great revelations, both in terms of understanding the history of billions of years ago and in terms of our own future. ”

“If conditions permit, I would like to build a semi-permanent observation station here to study these --”

Just as the excited Professor Vernal, and his dashing face Schultz, described his vision of the sky, suddenly the tremors of the mountains swung again at their feet.

Professor Vernal's expression on his face suddenly changed from ecstatic to frightening as he held the stone next to him and looked at the crushed stones and dust shaking from the ceiling.

“Fak?!" Again? ”

“We have to get out of here! ”

Standing still, the first Schultz to react grabbed his shoulder and tried to drag him out of here, but it was the discovery of spitting blood. The guy was like crazy and had no intention of leaving at all.

“Wait, wait for me to get some more samples back...”

A handful grabbed the multifunctional shovel in his hand and threw it out.

Schultz used all his strength to wake him from his stunned face.

“What the hell are you thinking!? ”

“If we stay here any longer, we'll all have to be specimens! ”

It was another violent sensation.

This time, without Schultz's reminder, Professor Vernal, who had returned to God completely, finally realized the seriousness of the problem and rushed to the nearest exit with a rolling belt.

Almost as soon as the two of them crossed the spacious cave and drilled out of the hole on the other side, the tunnel behind them closed like an avalanche.

A glance back, Schultz with a palpitation in his heart, suddenly a strange feeling in his heart.

No, that's an intuition, to be exact.

The collapse of these tunnels always seems unusual.

However, the situation now did not allow him to think too much.

He has no choice but to rush forward to feed his milk...

……

About the same time, in another tunnel.

After listening to Professor Aubrey's explanation, Professor Romonov touched his chin through the helmet of his costume, if there was a thought point, he said.

“I see...”

Aubrey: "Do you understand? ”

Romonov: "… perhaps? ”

When he heard the uncertain statement, Professor Aubrey sighed and threw the multifunctional shovel in his hand at his side, leaning against the rock wall next to him, fart. The stock sat on the floor.

“Chet… it seems I have spoken for nothing. ”

“It's a fog you're talking about,” Professor Romanoff complained. “What standard Euclidean space? And what kind of four-dimensional matter interferes with three-dimensional space… what does this have to do with earthquakes? ”

“Without an earthquake, the path under our feet hasn't even changed, and if I'm right, nothing would have happened if it had been swallowed up by that collapsed tunnel, but it would have moved from one three-dimensional coordinate to the other along with the space that was moved. ”

Romanoff: “Is this in keeping with the law of energy? ”

“The energy is constant? Of course, it was conservative,” Professor Aubrey marked the ground with a multifunctional shovel in his hand, sighing and continuing, "The state of motion of matter has not changed, nor has the energy changed, but the sequence in three-dimensional space has been disrupted. If you don't understand the standard Euclidean space, do you understand the hamster wheel? ”

“Are you all we are now like hamsters on a hamster wheel? ”

“You could say that," said Professor Aubrey, “this space is circular, and it's not possible to say the path we're taking at the foot right now, as we've done before. ”

Professor Romonov's face suddenly gave a strange expression when he heard about the cycle.

What he wanted to ask was, if that was the case, would it be necessary to keep moving forward?

However, just when he wanted to ask, the earth suddenly trembled violently, scared Professor Aubrey to stand up from the ground and look at the crushed stones shaking from the ceiling and the tunnels that could collapse at any moment, spreading his legs.

“WTF?! Isn't that every two hours? How many minutes has it been? ”

Romonov raced forward with a grunting stride, ripping his voice apart.

“Didn't you say it would be okay to be swallowed by that collapsed tunnel! ”

“I did! ”

“Then why are you running away?! ”

“Theory is one thing, experimentation is another! Besides, I'm just guessing, would you dare try your own life!? Shet, cut the crap and run! ”

The tiny stones and dust constantly fell from the top of the cave, hitting the heads and shoulders of the two.

The tunnel that collapsed behind me was getting closer and closer, and the leg script was not very convenient for two people, with a desperate look on their faces.

Yet at this time, a glimmer of light appeared ahead.

At the moment of discovery, Professor Aubrey's expression on his face lagged slightly, and despair turned into ecstasy.

“Exit! Exit ahead! Come on!”

I can't take that much anymore.

Although no clue could be found about civilizations outside the world, at least they survived. Congress may be disappointed in this, but Aubrey believes that if he dies in it, it will cause more trouble for his country and for the peoples of the world.

And as long as he's alive, then everything's fine!

“I will never go on an adventure like this again! Cough cough -”

Finally breaking through that desperate darkness, Professor Aubrey, who ran out of the tunnel, held his right hand against the stone column at the entrance to the cave, gasped desperately for a short while and slowed down.

Yet the moment he raised his head, the whole person was slightly stunned.

It's not just them.

Next to the Mars cart, including Wang Peng, who was separated from them, Fan Tong, and the archaeological Brits and the mathematical Germans are here.

Except for Master Lu...

Seeing Professor Aubrey run out of the cave, Wang Peng stepped forward and grabbed his shoulder with his hands. His eyes were covered in blood and stared at him dead.

The creepy feeling made him chill.

Professor Aubrey, staring straight into his eyes, felt like he had forgotten how to breathe for a moment.

“Where's the ark? Where is he? ”

“How do I know?” Trembling, Professor Aubrey replied shakingly, "I'm not his bodyguard, besides, isn't he with you?! ”

“ …… ”

Though not trusting this Yankee statement, Wang Peng eventually loosened Professor Aubrey's shoulder.

His eyes dropped to the swinging hole, his fists squeezed dead, and suddenly a glimmer of determination flashed in his eyes.

“I'll go find Master Lu. ”

Like looking at a madman, Van Tong stared at him.

“Are you crazy?! On the scale of the earthquake, this whole mountain range is afraid to be devastated! ”

“Then you go first...”

Before the end of the sentence, the people standing in the hole were suddenly trembling from the bottom of their feet, giving a twist. The shaking feeling of the mountain came from all sides, even the stone pillar standing at the door of the hole issued an overwhelming whisper and began to collapse towards the side.

By the time we saw the scene, all of us had changed their faces and rushed wildly to the next Mars car.

“Go, go, go! ”

“Wang Peng is not up yet! ”

“I can't care less! He's going to die, are you going to drag everyone to die with him?! ”

Listening to the roar coming from the communication channel, Fan Tong bit his teeth and looked back at the passengers sitting in the car.

Nobody wants to die, including himself.

Especially when death is unknown.

Ultimately, he made up his mind and said sorry. He grabbed two tanks of oxygen and threw them out the door, then started the Mars car at the fastest speed in his life.

There is no point in staying here, apart from burying Martians who died billions of years ago.

Avoiding the rocks that rolled off the ridge, Fantong used his milk strength to step the throttle to the bottom, and went on like a lifetime, finally rushing out of the narrow mouth that passed without risk.

Almost as soon as they had escaped, a giant rock wall about ten metres long, separated from the tall mountain ridge, burst into the narrow mouth through which they had previously passed in a piece of dust.

If they were one more second late, they might have been left inside forever...

Rolling gravel rises in the sand and dust, not to mention through the windows, even standing at the altitude of the satellite overlooking it, I'm afraid.

All the way through the desert, feeling the aftershock coming from beneath the seat cushion, looking back at the people behind, the face of the aftershock.

“Grass…”

He hit the steering wheel hard, slowing down the same speed, and suddenly knocked his forehead over it, shaking like a shoulder twitch.

Schultz silently patted him on the shoulder, expressing comfort.

Everyone in the car was silent, and there was no exchange of words on the way back.

Only Professor Aubrey whispered, "It's like a gateway to hell," and silently lowered his head after not receiving any response.

June 10.

This day.

Mars had the worst earthquake since human observation, and even the Mars Science Examination Station, a few kilometres away, could clearly feel the tremor of the mountains.

And that's the same day.

The Mars Science Examination Station lost two good players...
