Another world conquest manual

The location where Lei Wenjun got off the plane was near the cave, so after he regained his energy, it didn't take long for everyone to arrive at the cave.

After arriving at the cave, Lei Wenjun first asked his assistant to go to the edge of the pit to debug the equipment in preparation for the subsequent survey.

The debugging process is not simple. Whether it is fixing the instrument or calculating the irradiation angle, it is not an easy task.

He himself took advantage of this opportunity to come to the inside of the cave entrance and carefully studied the rocks near the entrance.

He first touched the surface of the gravel with his hand.

This rock wall that ordinary people can only say "no cracks" after looking at it for a long time, in Lei Wenjun's eyes is a sample that can provide a lot of information.

This is the difference between insiders and laymen, just like a certain veteran can make a short movie with less than ten letters + numbers.

Lei Wenjun then picked up a small tungsten steel sand drill and started digging into a non-load-bearing part of the rock wall.

Kakaka——

The drilling process lasted about two minutes, and the drill bit penetrated about 20 centimeters.

Then Lei Wenjun put down the equipment and replaced it with a set of precision probes.

Another five minutes passed.

Lei Wenjun stood up and said to Lin Ziming:

"Colonel Lin, the standard penetration number is probably in the early 50s, the rock wall structure is very clear, and the core has no obvious signs of fragmentation. This is standard moderate weathering."

Lin Ziming quickly asked:

"Medium weathering? Any specific year reference?"

Lei Wenjun thought for a while, pointed to a lady outside the cave entrance that was being blown by the breeze and said:

“Although the arc-shaped top of this cave is a typical wind outlet structure, the entrance is located on the side of the positive wind direction, so the wind is not particularly strong.

So combine these judgments.

It must have been more than 60 years ago that the cave began to show signs of weathering. "

"More than 60 years?"

Upon hearing this number, Lin Ziming and Patriarch Wei looked at each other and said thoughtfully:

"Master Wei, it seems that your guess is correct."

According to the Mo family genealogy records.

Mo Shaonan was born more than 270 years ago. He was taken away by Mo Peidong when he was seventeen years old. He disappeared when he was nearly ninety years old.

Therefore, the year of his disappearance was probably more than 180 years ago.

There is a discrepancy of about thirty years between this year and the C14 result produced by Wang Jun and others. Therefore, there is a high probability that 'Mo Shaonan' died after staying in the secret room for about thirty years.

Although there are still a lot of unresolved issues regarding the cause of death of the third ancestor of the Mo family who was taken away.

For example, practitioners at the fifth level of the Dan Formation Realm can theoretically live for more than two hundred years, and they should not die naturally so early.

But these are things that happen within specific nodes and have nothing to do with the timeline.

According to the previous guess of Patriarch Wei.

The third-level Cloud Hidden Talisman failed when no one input spiritual energy or provided spiritual stones for a long time, thus causing the cave to be exposed.

Lei Wenjun's test results basically provide numerical support for this guess.

Lei Wenjun then conducted sampling at multiple locations in the cave, and finally determined that the year the cave was exposed was more than 60 years ago.

Although human identification may not be as accurate as mechanical analysis, there is a certain deviation in theory.

However, no matter how large this error is, it cannot be as exaggerated as a hundred years - after all, surface weathering may behave differently due to various reasons, but the core is not that easy to go wrong.

After confirming this information, Lei Wenjun followed Lin Ziming and others to the edge of the pit.

At this moment.

A piece of equipment that resembled a dental machine that you would lie on during a dental visit had been placed above the entrance of the cave. Lei Wenjun's assistant, Feng Yuhua, was typing on the keyboard with both hands quickly, calculating data.

There is a saying that if you use this speed to write a novel, it will cost you at least 30,000 words per day.

After arriving at the pit.

Seeing that the relevant equipment was still being debugged, Lei Wenjun squatted down and observed the deep pit with his naked eyes.

Lin Ziming looked at Lei Wenjun and said half as a joke and half as a reminder:

"Old Lei, be careful. If you fall into this pit, you will be dead."

Lei Wenjun nodded and suddenly let out a light sigh.

Then he crawled to the ground and reached down with his right hand.

Click——

He gently broke off a stone that was forty to fifty centimeters deep inside the pit.

Then Lei Wenjun took out his hand, looked at the stone, frowned and said:

"What's wrong is that this rock is different from the rocks at the entrance and inside the cave. It's completely different."

Lin Ziming looked at him and asked:

"How to say?"

Lei Wenjun first pointed at the entrance and roof of the cave. The places he pointed at were all standard brown rocks. He just heard him say:

"The rocks inside and at the entrance of the cave are common phyllite and basalt, with a slight hint of gneiss on the outside - this is a common rock in both the mainland and the Great Mo World. It evolved due to the oxygen content and the gravity of the planet. Regular variety.”

Then he showed the stone in his hand to Lin Ziming, pointed to the bumps on it and said:

“But this rock is different, it’s kind of like an ultramafic intrusive rock.

Colonel Lin, have you seen the granular structure and blocky structure on it?

This shows that its metal content is very high, either iron or magnesium.

I had seen this area when I came here. It is a standard sloping terrain and there is no possibility of metal veins. "

Lin Ziming looked at him thoughtfully:

"Director Lei, do you mean it was placed here? Or even man-made?"

Lei Wenjun was silent for a while and shook his head:

“It’s hard to say, I can only say it’s possible, after all, it’s just a sample.

The Great Mo Realm is mysterious and unpredictable, and there may be some geological structure beyond our concepts. "

Then he looked at his assistant Feng Yuhua and asked:

"Yuhua, is the rangefinder ready?"

Feng Yuhua nodded quickly and replied:

"The mine station, data and inclination have been debugged."

This time Lei Wenjun and the others brought an ultra-long-range laser rangefinder, which was more than four times more effective than Lin Ziming's.

This rangefinder can be said to be the farthest measuring device except astronomical equipment. The principles of astronomical equipment are completely different and cannot be compared.

The positioning of this detector is actually ultra-long-distance detection under extreme conditions.

After all, the Great Mo Realm is different from the mainland. After the day, there are 168 hours of night. It is impossible to work normally in the wild without some powerful equipment.

Even when the command headquarters first prepared this machine, one of the possible uses it considered was 'depth detection of unknown potholes'.

After all, it is difficult to detect in the wild, but there are only a few theoretical projects, and they can be listed by exhaustive methods.

According to the original design.

Under normal circumstances, this device can detect a range of 100 kilometers.

That is, it is almost the same distance from Chongming Island to Songjiang.

Lin Ziming then confirmed that the generator he brought was enough to support the maximum power of the detector, and said to Lei Wenjun:

"Director Lei, let's get started."

Lei Wenjun was already standing next to the main console. He nodded and said to Feng Yuhua:

"Yuhua, turn on the phone!"

Feng Yuhua's hands once again typed out the afterimage on the keyboard, and at the same time at least said:

"The measured inclination angle is 7.29°, the output power increases from 500 milliwatts, the red text is pulled to the far left, start!"

The next second.

The laser rangefinder received the command and instantly emitted a subtle red light.

call out--

Everyone knows that the speed of light is 299792.458 kilometers per second.

The irradiation distance of this equipment at its ultimate power is 100 kilometers, which means that it only takes less than a blink of an eye from the time it is emitted to when the laser reaches its limit.

But what made everyone feel cold was...

After a few seconds, the screen was still blank.

In other words, the depth of this cave entrance exceeds 80 kilometers, or 80,000 meters.

Lei Wenjun's eyes were fixed on the screen. After a while, he suddenly said:

"Yuhua, prepare the rope, I want to go down into the pit!"

I don’t know what’s going on. I feel unexplainably uncomfortable. I’m vomiting like crazy. I guess I’ve eaten something bad.

Also recommend a book, "I Entered the Dark Paradise"

Thriller and suspense. The sound of an awl was heard from the unoccupied room next door. The dark marks of the human figure on the wall were getting darker and darker. There were footsteps outside the door, but when the door was opened, there was no one there.

A cold hand placed on Chu Xiao's shoulder, and a cold voice came, "Welcome to the Dark Paradise."
