It's reasonable for me to have a two-way foil for a second-level civilization, right?

Hearing this, the faces of the five teammates all flashed a thick look of shock.

"Similar to Earth?!"

"Captain, are you sure?!"

Hong Fan smacked his lips and turned his head to look around.

In the Gale crater, the eyes are red.

In addition to fine gravel, there are large rocks everywhere.

In such an environment, it is possible to breed life like the earth?

Bai Yixuan shrugged: "Professor Lu said, but don't have too much hope, the probability of this happening is very small."

……

The foot of Mount Sharp, inside Gale Crater.

Andrew and Bruno squatted down and gently brushed off the red Martian sand on the surface with a tool, exposing the ground with a little texture inside.

"Is this sedimentary rock?"

Bruno's eyes lit up, and he quickly stood up and waved to his teammates.

When everyone approached, Bruno pointed to the ground and said excitedly: "Everyone, look, what is this!"

"Typical sedimentary rock!"

"This kind of texture is generally only formed under the transport and deposition of water and glaciers!"

Through the glass mask, Bruno saw the surprised expressions on everyone's faces.

He reached out and tapped the rock in front of him lightly: "Professor Lu is right."

"Anyway, this place may have been a lake in the past, and there is indeed the possibility of life."

Bai Yixuan squatted down, stretched out his hand and gently brushed the rock in front of him.

Through the glove, he clearly felt the texture of the rock surface.

At this moment, he held his breath slightly.

As if what he touched were not rocks, but the pulse of the billions of years of Mars!

After a long time, he exhaled a long breath, stood up and said, "Just this way."

"Hong Fan brought the drilling equipment, let's see what's going on underground!"

……

With the joint efforts of six people, the drilling equipment was quickly set up again.

Under the joint action of the motor and the drill bit, the crimson stone chips flew out quickly.

Due to gravity, some fine dust floated in the air, but it has not landed for a long time.

The air around the borehole quickly became cloudy.

Bai Yixuan, who was in charge of controlling the drilling equipment, glanced at the monitor beside him through the turbid air.

Looking at the various data displayed above, Bai Yixuan shook his head helplessly.

"This place is really difficult to drill. I guess the bottom is all sedimentary rocks?"

As soon as the words fell, the drill bit sank instantly as if there was no obstacle!

"Fuck!"

Seeing the rapidly descending drill bit, Bai Yixuan had no time to think, and pressed the emergency stop button with muscle memory.

"team leader?!"

This momentary movement obviously frightened several teammates next to him.

"What's going on? Why the drill..." Hong Fan squatted down with fear on his face, observing the drill.

Bai Yixuan swallowed slightly, stood up slowly, and pressed the motor reverse switch with trembling hands.

"I don't know either. It doesn't seem to be a rock formation below."

Chapter 196 Mars Simulation Results

After the sampling work is completed, with the reverse rotation of the motor, the long drilling rod is quickly drawn out from the surface.

For the first five meters, there was nothing unusual.

The surface of the drill pipe was covered with crimson cuttings.

But the next picture is a little different.

A deep red.

Seeing this obvious color difference, Bai Yixuan's eyes revealed a bit of uneasiness.

Being on a different planet, facing this unknown situation, anxiety and worry are extremely common psychological phenomena.

Not only Bai Yixuan, but also the other five teammates showed a bit of worry on their faces.

"Captain, this..."

On the radio, Xia Wanyi's voice came.

"Calm down." Bai Yixuan said softly while taking a deep breath, "We'll see the situation after all the drilling rods come out."

There was silence on the team's radio channel.

All eyes were fixed on the drill rod in front of them.

The motor stopped.

Bai Yixuan and Hong Fan, as the two closest to the drilling rod, discovered the problem immediately.

"Wet?" Hong Fan stared blankly at the drill rod in front of him.

Subconsciously, Bai Yixuan stretched out his hand to touch the drill rod, and then twisted it lightly with his fingers.

"No, to be precise, it should be trendy."

……

No. 1 Mars City.

"Five meters underground is wet soil?!"

Lu Yongchang looked at the holographic image in front of him in disbelief.

"Professor, it should be moist Martian dust glued together." Ling meticulously corrected Lu Yongchang's slip of the tongue.

"It does not matter!"

Lu Yongchang waved his hand casually, frowning into a ball.

"The point is, how could it be wet? How could it be wet?!"

"Zero, what is the surface temperature of Mars now?"

Zero quickly responded to his question: "It is currently noon in Gale Crater, and the surface temperature is 10 degrees Celsius. Due to the influence of the sun, the temperature is about 20 degrees Celsius higher than the same period in previous years."

Lu Yongchang frowned.

10 degrees Celsius, which does raise the possibility of liquid water.

"What's the temperature at night?"

"Yesterday night, the surface temperature of Gale Crater was -25 degrees Celsius, about 15 degrees Celsius higher than the same period in previous years."

Lu Yongchang shook his head solemnly: "No, this is not right."

"Such a temperature is absolutely not enough to melt the ice five meters below the ground!"

"Could it be the effect of underground magma?" Just as Lu Yongchang was struggling, a familiar voice came from the door.

Lu Yongchang trembled slightly, apparently startled by the sudden sound.

He quickly raised his head and looked towards the door.

"Brother Xu?"

"Why are you here?" Seeing the person coming, Lu Yongchang's eyes showed a bit of surprise, "No, when did you come?"

Fang Xu skillfully pulled away the chair in front of the desk, and said hello to the mechanical arm beside him: "Ling, make me a cup of tea."

After seeing the mechanical arm moving, he turned his head to look at Lu Yongchang: "I just came here not long ago, probably when you were struggling with the surface temperature of Mars."

A cup of hot tea was handed to Fang Xu.

He reached out to take the teacup, nodded his thanks to the robotic arm, and continued, "I'm here for the medical cabin."

"Medical cabin?" Lu Yongchang frowned even deeper, "What happened to the medical cabin?"

Fang Xu shrugged: "Academician Mao said that the basic functions of the medical cabin have been researched almost, and it is estimated that it will not be long before it can be truly realized."

Hearing this, Lu Yongchang's frown was relieved a lot.

This should be the first good news after coming to Mars.

The breakthrough in medical cabin technology will greatly extend the average life span of human beings.

Although the lifespan of more than a hundred years is not enough for an interstellar civilization, it is always a good thing to have a breakthrough.

"So, what you just said, what is the underground magma activity?"

Lu Yongchang brought the topic back: "There is no large-scale magma activity on Mars, you should be clear about this."

"You also said that there is no large-scale magmatic activity." Fang Xu said while drinking tea, "I am just giving you a guess. Maybe there is a little magmatic activity under the Gale Crater."

Lu Yongchang nodded silently.

Perhaps only this reason can explain the existence of liquid water.

"Professor, the full report on the drilling samples is out."

With Zero's voice, a report appeared in front of Lu Yongchang.

"Sedimentary rock?!"

"There are obvious traces of water erosion and deposition?!"

Looking at the data in front of him, Lu Yongchang's eyes shone with excitement.

"Sure enough, Mars was really a habitable planet before!"

Fang Xu also put down the tea cup in his hand at this time, and looked at the test data provided by Zero with a look of surprise.

This is a subversive discovery!

"If there is water flow, then there may be more types of minerals on Mars than we imagined?" Fang Xu asked softly.

"That's the reason." Lu Yongchang nodded quickly.

"It's just that it's still not as good as Earth."

"Of the more than 4400 minerals known on the earth, more than 2900 are related to biological activities."

"On Mars, it is obviously impossible to have these minerals."

With that said, Lu Yongchang turned his head and gave an order towards Zero.

"Zero, let Bai Yixuan and the others drive Xuannv-[-] to do a complete survey of Gale Crater."

……

a few days later.

"Professor, the survey data is out."

The holographic projection unfolded quickly, and a thumbnail of the full picture of Gale Crater appeared in Lu Yongchang's office.

"Zero, do a simulation of the structure and texture inside the crater."

"See where the water comes from."

After a few minutes.

"Professor, the simulation results are out."

Arrows and water flows began to appear on the holographic projection: "According to the simulation results, part of the water comes from the surroundings, which is the so-called rainwater."
