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

Feng Yuanliang nodded again and again: "That's right, it's such a process."

"Academician Fang, look." He reached out and dragged a holographic projection, "We assume that Guangwei-[-] had a relatively complete atmosphere before."

"Under the strong gravitational force of Dawn Star, its atmosphere is enough to generate an extremely powerful storm!"

"Similar phenomena have been found in human history."

"Back then, humans discovered hematite on the surface of the moon."

"It's unbelievable, isn't it?" Feng Yuanliang sighed in his eyes, "How can there be hematite on the surface of the moon without any atmosphere?"

"The reason behind it is actually very simple."

"The strong solar wind blows oxygen from the Earth's surface toward the moon, thus forming hematite."

Fang Xu was slightly moved, and quickly said: "Zero, simulate it, and see if such a situation may occur on Dawn Star."

After a few minutes.

The scene described by Feng Yuanliang appeared in the holographic projection.

"Then... how to prove the correctness of this conjecture?" Fang Xu asked softly.

In the absence of conclusive evidence, speculation can only be speculation.

"Simple."

Feng Yuanliang pondered for a moment, a gleam flashed in his eyes.

"Let these exploration teams do deep drilling work."

"If nothing else, the hematite will only be evenly distributed at a certain depth."

Fang Xu thought for a moment, and suddenly realized.

This is true.

Under the influence of the powerful storm on Dawn Star, the hematite powder will inevitably be evenly distributed all over the world.

The so-called specific depth depends on the integrity of the moon's atmosphere.

When the atmosphere of Guangwei is loose enough to be unable to set off a strong enough storm, these hematite powders, like water without a source, will eventually be buried under the yellow sand.

Only a small amount of hematite powder will be lifted up by a powerful storm and dispersed in the atmosphere!

Chapter 401 Deep Drilling Sampling

Fang Xu pondered for a moment, then reached out and opened the public communication channel on the console.

"Attention all investigation teams."

"According to our comprehensive consideration, the hematite you discovered is very likely to come from Guangwei."

"However, this is only an inference based on current information."

"I need you to conduct a deep drilling sampling operation immediately."

"And send the drilling sampling results to 【Earth】."

"Repeat, start deep drilling and sampling immediately, this task has the highest priority!"

After speaking, Fang Xu cut off the communication, then turned to look at Feng Yuanliang beside him.

"Now, just wait patiently for the drilling results of these exploration teams."

Feng Yuanliang nodded lightly, and murmured in a low voice, "I hope this is the result."

If the actual drilling results don't match up with the speculation, then the fun is on!

……

dawn star.

Inside the planetary landing vehicle, the atmosphere is extremely dignified.

"Ding dong."

A crisp reminder sounded in the cabin, and a line of faint words slowly appeared in front of everyone.

[Current outside wind speed: 20km/h]

A look of disappointment flashed in Hong Fan's eyes.

Not the information he wanted to see.

Although wind speed information is also critical, at present, the mystery of hematite is the focus of all team members.

"Captain Hong, do you think there will be..."

Bruno's voice came from behind Hong Fan.

Before Hong Fan could answer, a loud electrical sound rang through the communication channel.

Because the distance is relatively short and the signal is not interfered much, the communication between the fleet and the surface still uses the simplest electromagnetic wave communication.

In less than a second, the sound of the current decayed rapidly, and Fang Xu's voice came out from the communication channel.

"...from Guangwei."

"..."

Communication ends.

The interior of the planetary landing vehicle was so quiet that Hong Fan could even hear his own heart beating.

"... Zhuan."

I don't know who it was, and let out a slight "sigh".

Like a signal, this "sigh" instantly ignited the atmosphere in the planetary landing vehicle.

"It's been a false alarm for a long time, right?"

"Don't talk about Xingde, come to steal, come to lie to me, a 100-year-old comrade!"

"..."

Listening to the complaints around him, Hong Fan couldn't help but shook his head with a wry smile.

He also didn't expect that the answer turned out to be the light satellite above his head.

Although he wanted to complain, but as the captain, he could only suppress the impulse in his heart.

Even, he needs to pour cold water on his teammates who let down their vigilance.

"Cough!" He coughed lightly, suppressing the voices of complaints in the cabin, "Everyone be quiet."

"Didn't you hear what Academician Fang said just now?"

"As of now, these are just speculations, and there is no conclusive evidence to prove this speculation."

Under Hong Fan's basin of cold water, the "hot" atmosphere inside the planetary landing vehicle gradually cooled down.

"Do we need to conduct drilling samples now?" Xia Wanyi's voice came from the side.

Hong Fan's face instantly became serious.

"Of course." He nodded, "This is the highest priority task."

"It's just...a matter of selection."

"Deep drilling and sampling requires at least two people to complete."

The atmosphere inside the planetary landing vehicle froze a lot again.

Humans cherish their lives.

"I'm in charge of the drilling rod." As the team leader, Hong Fan naturally spoke first, "But I need someone to help me start the drilling machine."

"Let me go." Andrew grinned, "Captain Hong, I'm familiar with this stuff."

Hong Fan: "..."

Bad memories flooded up again!

Andrew is in charge of the drilling machine as he searches for life on Mars!

And he, of course, is responsible for the part of the drilling rod.

Although a little dirty and tired, the drill rod is the most important thing in the whole drilling work.

Before the People's Union was established, Hong Fan didn't dare to let Andrew and the others touch such important components.

Of course, after the establishment of the People's Federation and the completion of the construction of Mars City, this combination is still the same.

There is no other reason, but familiarity with hands.

"Row."

Hong Fan didn't say much, and after saying hello, he got up and walked towards the cabin behind the planetary landing vehicle.

……

After ten minutes.

The hatch of the planetary lander opened again.

Hong Fan and Andrew, who were fully armed, came out with simple drilling equipment.

The feeling of stepping on the fine yellow sand with both feet raised Hong Fan's vigilance to the highest point.

He glanced at the planetary lander behind him.

On the roof of the car, the muzzles of the two small laser cannons shone with a faint blue light.

Inside the car window, Xia Wanyi gave him an ok gesture.

Hong Fan breathed a sigh of relief, and his tense muscles relaxed a lot.

He picked an area at random, squatted down, and assembled the drilling rod bit by bit.

Unlike the drilling equipment used on Mars, the current deep drilling equipment has completed several "evolutions".

While the body is lighter, the drilling efficiency is also greatly improved.

"Team Hong, what is the depth of the first drilling?"

Andrew asked in the team communication channel.

Hong Fan pondered for a moment: "The command center didn't specify the specific requirements."

"Let's try to see the depth of one meter first. If there is any problem, we can lengthen the drilling rod."

Andrew nodded, lowered his head and began to operate on the drilling machine beside him.

……

After a few minutes.

Drilling equipment is assembled.

Under Hong Fan's signal, Andrew carefully pressed the drilling button.

The drilling rod rotated rapidly and sank into the ground at a speed visible to the naked eye.

Looking at the various data in front of him, a trace of surprise flashed across Andrew's face.

"Team Hong."

"There's very little resistance to the drill rod."

Looking at the drill pipe that had sunk [-] centimeters into the ground, Hong Fan asked with a serious expression, "What substance is the preliminary determination?"

At this point, the drill pipe is still rapidly penetrating.

"Most likely, it's fine gravel compacted by gravity."

As soon as the voice fell, the sinking speed of the drill pipe decreased rapidly.

Andrew's eyes moved slightly: "It should be hitting a rock now."

"...Wait, that's not right!"

Seeing the prompt on the monitor, Andrew's voice suddenly became excited: "Not just rocks! There is also elemental iron ore!"

"Team Hong! In addition to the nearby rock walls, there may be a lot of metal iron in the form of simple substances underground!"

There was also a little joy in Hong Fan's eyes.
