About twenty minutes drive, the Mars car reached the edge of the “Gate of Hell”.

Found a narrow exit along the waiting line that allowed the Mars car to pass, Fantong hit the steering wheel and drove the car past.

As the Mars cart continues deep into the mountains along the rugged narrow trail, the signal is affected by the nearby Red Iron Ore and begins to break.

With a glance around the steep cliffs and rock walls, and the depressing atmosphere, astrophysicist Aubrey shrunk her neck and couldn't help but vomit.

“By the way, why is this called the Gate of Hell? Don't you feel panicked about giving this name here? ”

The range of driving was random, he said.

“I'm afraid you have to ask NASA, they took the name. ”

As the earliest institution to send a probe to Mars, slightly larger terrain fluctuations were basically given a name by the curiosity sign.

Perhaps the named researcher thought the word was more artistic and bacterial, so he named it after the mountain range. Now, it's hard to say if there's an art bacterium, but the image has nothing to say about it.

“Around the gates of Hell there are random cracks several metres long, which resemble seismic cracks through which you can enter directly into the ruins. Of course, these cracks were not the only way inside the ruins, and when I came out of the ruins, it was through a fixed entrance and exit. Its location is probably in the middle of the Hell's Gate Mountains, embedded on the rock wall on the side of the Rift Valley… right in front of us, here we are. ”

Moving forward along the Rift Valley, the Mars car that shut down the engine slowly stopped next to a ridge. After the pedestrians got out of the car, they followed Fantong's footsteps to a standing stone column about four or five people tall.

Behind this pillar you can see a steep downhill.

The dawn glow shines on the back of the pillar, pulling a divine glow down the trajectory of the shadow. Just like some natural miracle, watching alone is irresistible.

If you look only at the shape, it does feel a little relic.

“… a little strange. ”

There was a slight sound in his mouth, and Professor Vernal, an archaeologist from Oxford University, frowned and squatted down in front of the stone column. After a short stroke along the surface of the stone column, he suddenly continued.

“This is a marine sediment environment? ”

Standing behind Professor Vernal, Fan Tong's face revealed a slight surprise, nodding his head and saying.

“I agree with you… billions of years ago, this was supposed to be an ocean. ”

“And most of the altitude is still a little deep," Professor Vernal muttered as his palms stroked along the contours of the stone column and felt the hard touch coming through the graphene fibers, "the hydrogeological environment here is a bit unique and there should have been many major geological disasters in history. Volcanic eruptions, plate collisions, and those special tectonic movements that don't exist on Earth… are incredible. ”

“Let's focus on the ruins underneath, rather than on the geology here," astrophysicist Aubrey walks in front of a pedestrian, turning back to the ark and leapfrogging, “don't you think?” Boss.

“I don't have an opinion, but I'm afraid we won't be able to figure anything out just standing outside," said the ark after a moment of reflection, "Keep going, I'll take the lead. ”

Wang Peng lifted his hand and placed the paratrooper rifle with the torch in front of him and took the initiative to reach the hole.

“I'll do it. ”

Aubrey and Vernal met and exchanged a strange gaze. Fantong also shrugged his shoulders helplessly and threw a sample of the stone he pinched on his hand aside.

“As I said, weapons may not be useful… but if you insist, do as you please. ”

While that is true, it has to be admitted that a gun driving in the front still gives a lot of security to a pedestrian.

Even if it is clear to everyone that if something really happened to a living alien, most weapons on Earth would be difficult to guarantee that they would retreat from their bodies. But at least in the heart, the gunpoint of that black hole can bring some comfort to them.

Walking next to the ark, Schultz whispered.

“Are you sure those Martians are... dead? ”

Looking vigilantly at the surrounding environment, the ark shrugged its shoulders and responded with a casual tone, “I'm not sure… but if they hadn't died, we would have seen them on Earth by now. ”

Billions of years in this universe…

Even if the Milky Way had not been occupied, the solar system would have been surrounded by thousands of light-years of stars, long overdue.

At this point, Dr. Romonov, a space engineer who had never spoken, suddenly jumped out of his mouth.

“Would we have met, just that we didn't realize? ”

Upon hearing this, Aubrey couldn't help but squirm and cough.

“Stop telling such ghost stories! ”

A pedestrian continues to march deep into the tunnel.

Until now, the adventure has been smooth and has not encountered any ripples.

Leaning against the mark that Fanton had previously left when he came out, they successfully advanced at least two kilometres towards the * * section of the hole. And according to the depth detectors, they're now about 200 meters from the surface.

The deeper their steps go, the stronger the feeling of alienation from civilization becomes. This feeling is like a baby who just cut his umbilical cord and was thrown into a deep, bottomless well.

There is less and less communication between them, be it conversational or neurotic, and everyone is silent by implication.

At this point, Fan Tong suddenly stopped and looked at the fork in the road ahead and said.

“Something's wrong...”

Everybody stop.

Looking at Fan Tong, who stopped, the ark threw a gaze at him asking questions.

“What's the matter? ”

“Marks are interrupted here. ”

Walking next to the rock wall, Fan Tong reached over and grabbed a scratch that had been cut from it.

This was the mark left by the multifunctional shovel when it first came out of the ruins, and this clue was supposed to point directly to the deepest depths of the ruins, but it is now truncated.

Looking at the two forks in front of him, Fan Tong's expression grew heavier, muttering to himself.

“It turns out… the passage inside the relic has changed, I didn't see any forks here in the first place, I had to walk about a kilometre backwards to meet the first fork. ”

“However, the fork appeared early. ”

“I'm afraid it's not just as simple as getting out early. ”

Mumbling to himself, Professor Vernal walked up and squatted beside the fork, chipping some debris from the rock wall with the multifunctional shovel in his hand, pinching it on his hand for a moment.

“… incredible. ”

Schultz swallowed his mouth and looked at him and asked.

“Incredible what? ”

“Three billion years ago… or earlier, this was supposed to be a cave full of alloy," Standing up, Professor Vernal carefully packed these rock chips into sample bags and labeled them, "although the traces of civilization had been weathered out of time, the rocks would not lie. ”

Professor Aubrey frowned.

“What are you talking about? ”

“I mean, from the weather trail, the structure of this road on the left is obviously more complicated than this road on the right," Professor Vernal continued to look at the ark, shrugging his shoulders, “You're the captain, which way to go, you choose. ”
