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

In the early days of infrastructure construction, human demand for iron ore was enormous.

If this piece of iron ore that exists in simple form is a rich mine, it will undoubtedly be great news for the current human civilization!

"Drip! Drip! Drip!"

The drilling equipment gradually stopped running, and a short reminder sounded.

[The preset depth has been reached, and the drilling has been completed]

Chapter 402 Layered Soil

Looking at the text on the AR display of the helmet, Andrew quickly reached out and operated the drilling machine.

The next moment, driven by the motor, the drilling rod gradually withdraws from the ground made of thick gravel.

With the cooperation of the two, the drilling rod was brought down on the yellow sand.

Then, Andrew pressed a button carefully.

The samples in the drill pipe poured out of it, forming a meter-long, layered "ribbon" on the ground.

It is completely consistent with Andrew's speculation.

The sample of the first 60cm is composed of countless fine sandstones and a little soil.

Under the action of 1.9g of gravity, a large amount of sand and gravel are combined with sparse soil and fit together tightly.

And the color of the gravel, from light to dark, gradually transitions from yellow to reddish brown.

The reddish-brown part is naturally the hematite they discovered earlier.

However, the strange thing is that the reddish brown only occupies a part of the area.

As the depth increases, the color of the gravel turns back to its original yellow color.

After discovering this phenomenon, Hong Fan quickly squatted down, took out the measuring tool from the backpack behind him, and took a simple measurement.

It can be distinguished by the naked eye alone. The yellow area is composed of ordinary sandstone, which is mainly distributed at 0-11cm and 44-61cm underground.

The reddish-brown area contains a large amount of hematite, mainly distributed at 11-44cm underground.

And, within this range, as the depth increases, the content of hematite will gradually increase.

Once it exceeds 44cm, the hematite content will drop sharply, and it will disappear quickly within 2cm, leaving only ordinary sand and gravel.

After exceeding 61 centimeters, there is no soil and fine gravel in the drill pipe, only yellow hard stones are left.

The depth continues to increase.

more than 80 cm.

Some silver-white substances with metallic luster appeared in the stone.

As the depth increases, the content of silver-white substances increases significantly.

After some simple tests, Hong Fan determined the composition of the silver-white substance.

Elemental iron.

Without any hesitation, Hong Fan directly sent all the collected information to [Earth].

"Prepare to use a two-meter drill pipe."

Hong Fan greeted Andrew, then reached out and grabbed the drill pipe on the ground, ready to start the assembly work.

Suddenly, there was a slight electric sound from the communication equipment.

"Hey, hello? Can you hear me?"

"Hong Fan, can you hear me?"

It was Fang Xu's voice.

A hint of surprise flashed in Hong Fan's eyes, he stopped what he was doing, and quickly switched communication channels.

"Academician Fang, I can hear you."

"Hong Fan, we have read the uploaded drilling results, now..." Fang Xu's voice paused, "Let Academician Feng Yuanliang tell you."

"Comrade Hong Fan, hello, I'm Feng Yuanliang." A strange voice came from the communication channel, "The main research direction is the mineral resources of the universe."

Hong Fan was stunned for a moment, then hurriedly greeted him in a respectful tone: "Hello, Academician Feng."

Feng Yuanliang said bluntly: "At critical moments, I won't say polite words."

"Next, you need to change the area and conduct drilling and sampling work again."

"The drilling depth is still one meter."

Hong Fan nodded, without asking any further questions, he directly grabbed the drilling rod on the ground, waved to Andrew, and then walked towards the next sampling point.

……

【Earth】, in the biological laboratory.

"Next, we need to compile the related genes of Magna again."

Lu Yongchang's voice showed a little fatigue: "The work in this area is relatively simple, but it is a bit cumbersome."

"Academicians with experience in the research and development of longevity enzymes will give you a hint, and this task will be entrusted to you."

"I need a little rest."

Mao Zhengzhi nodded lightly to express his understanding: "Professor, I will call you after I finish this work."

Lu Yongchang briefly explained the precautions in gene compilation, and then turned to leave.

"Professor Lu!" Suddenly, there was a burst of excited cheers in the distance. A scientific researcher ran up to Lu Yongchang with a red face, and said in a hurried tone, "Professor, we succeeded! We succeeded!" !"

"What?" Lu Yongchang hadn't recovered from the work just now, and asked in a daze, "What succeeded?"

"We successfully implanted the first gene in E. coli!"

The researcher excitedly explained: "According to the data of the Proxima Centauri civilization, the main function of this gene is to strengthen the heart muscle of Magna."

The fatigue in Lu Yongchang's eyes disappeared in an instant. He stretched out his hand and rubbed his stiff face vigorously, then he pulled himself together and asked, "Has the corresponding hormone been detected?"

The researchers nodded again and again: "It has been discovered."

"However, it has not been purified and no biological experiments have been carried out, so it is not clear whether its function meets our needs."

Lu Yongchang turned his head to look at Mao Zhengzhi, and winked at him.

Afterwards, he raised his hand and greeted Mao Zhengzhi: "Come on, let's go and have a look."

"If possible, we will do the first set of experiments now."

Mao Zhengzhi smiled bitterly when he heard this: "Professor..."

"Didn't you say you want to rest?"

Lu Yongchang shrugged: "Rest?"

"Isn't this a rest?"

Mao Zhengzhi: "..."

……

dawn star.

The distance between No. 50 sampling point and No. [-] sampling point is [-] meters.

With their first drilling experience, Andrew and Hong Fan's operations became more and more proficient.

With the cooperation of the two, the second tube of samples soon appeared in front of everyone.

Looking at the sample that was almost the same as the first tube, Feng Yuanliang's excited voice came from the communication device: "Hong Fan, measure the corresponding data!"

Hong Fan quickly squatted down, took out tools and started measuring.

"The yellow areas are 0-9cm and 39-57cm respectively."

"Red zone, 9-39cm."

While measuring, he reported item by item data in the public communication channel: "57-79cm, most of them are ordinary rocks, after 79cm, the content of elemental iron increases rapidly."

There was a moment of silence in the communication channel.

"call……"

Feng Yuanliang took a few deep breaths, suppressed the excitement in his heart, and said in a deep voice: "Currently, the number of samples is insufficient, so we will continue to change spots for investigation."

"Next, we need to observe the sampling results of other ore prospectors."

"Just upload the relevant data directly."

Hong Fan nodded, stood up subconsciously, and put his hands on the rock wall beside him.

shuffle shuffle...

A fine cloud of dust fell from the rock face.

This scene was completely recorded by the camera carried by Hong Fan.

Chapter 403 The Storm is Coming

Feng Yuanliang, who was about to cut off the communication, suddenly froze in place after seeing this scene.

His eyes widened slightly, and he shouted hurriedly, "Don't move!"

Hong Fan, who was on Dawn Star, was just about to move his left hand that was propped on the rock wall, when he suddenly heard the voice from the communication device, and his body trembled slightly.

But his good personal qualities made him calm down quickly.

He kept his original movements, his muscles were tense, and his concentration was high. He lowered his voice and said, "Academician Feng, what happened?"

While talking, he observed the surrounding scene with the corner of his eye.

Didn't find anything unusual?

Except for the fine sand that slid down the stone wall and went with the wind.

Hong Fan's eyes suddenly showed some doubts.

Even Fang Xu on the [Earth] looked puzzled at Feng Yuanliang who was holding the microphone beside him: "Academician Feng?"

Feng Yuanliang said softly, "Hong Fan, move your hands away first."

"slower."

"Aim the camera at the rock wall."

Faced with Feng Yuanliang's request, Hong Fan naturally followed suit.

The departure of the left hand naturally brought down a piece of fine yellow sand.

Visible to the naked eye, there is a small pit full of holes on the already uneven rock wall.

"What a serious weathering phenomenon..."

Feng Yuanliang muttered to himself in the communication device.

Hong Fan breathed a sigh of relief.

I thought something happened, but it turned out to be just weathering.

He waved his hand nonchalantly, and said carelessly: "Academician Feng, it's normal for the wind to be severe on the Dawn Star."

Unlike Hong Fan, Feng Yuanliang's voice was extremely dignified.

"Do not."

He softly denied Hong Fan's words: "Such a serious weathering phenomenon is not something that can be done with this little wind."

In the communication device, there was a dead silence.

"...What, what do you mean?"

Hong Fan admitted that he started to panic.

What do you mean it can't be done with just a little wind? !

Feng Yuanliang pondered for a moment, then said again: "Adjust the camera to wide-angle mode, and let me see the landforms near you."

Hong Fan hurriedly followed suit.

This mine is located in a narrow canyon.
