Zheng Ya is really not talking about it.

In the twenty-fourth year of Kangxi, the Qing Mongolian Sagang Chechen wrote "The Source of Mongolia", which was called the "Historical Records" of the Mongolian people in later generations.

Sagang Chechen was called Sima Qian of the Mongols by later generations.

Precisely, the death of Genghis Khan recorded in "The Origin of Mongolia" is the version that Zheng Ya said.

No one can tell what is really going on in history.

Perhaps, it is not necessary that there are more secrets hidden in it, Zheng Ya now knows that behind the prosperity, there are often many unknown secrets.

Just as the truth is in the hands of a very few, the truth of history may be known only to a very few.

Lin Zhiyu didn't know what was wrong with Zheng Ya's scientific expedition, and in her worldview, scientific research was actually likely to be a noble and mysterious sacred mission.

If it weren't for the nervousness of his studies, maybe Lin Zhiyu would happily go to the scientific examination with him.

I don't know why, after chatting with Lin Zhiyu, Zheng Ya's heart gradually calmed down, there are many hidden things in this world, and when his ability reaches a certain height, he will unveil some mysteries for himself.

Like the purpose of darkness, he has unconsciously become a walker walking in the darkness, and in the process of moving forward, he guards the light in his own way.

Guarding the people they need to protect, so that their lives are full of sunshine and hope, such as words, such as Meimi.

The fact that he is about to travel far away, Mei Mi already knows.

However, after the football final, I need to go to Mei Mi to talk about it, and this time, it is estimated that I will not be able to come back in a day or two, but I have to comfort myself first.

For the first time, Zheng Ya didn't have a code word, so he spent some time and accompanied him before going out for the evening practice.

The ability is accumulated little by little, and the progress is also achieved little by little, and I don't know what I will encounter when I go out on this scientific expedition, and I must be ready to go.

The next morning, after Zheng Ya got out of class, he came to the school archives according to Xiaofei's tutor's explanation.

Tutor Xiaofei said that he left some scientific research equipment for himself here.

Zheng Ya's heart was full of curiosity and wanted to see it, this was the first set of professional equipment that Zheng Ya got after choosing a geology major, and he wanted to know what it was.

The old man guarding the archives was quite dedicated, and quickly found the secret room for Zheng Ya, and carefully explained the situation to Zheng Ya, and asked Zheng Ya to ensure that the news of the secret room would not be leaked, which gave Zheng Ya the qualification to enter the secret room.

Zheng Ya stepped into the secret room, and the old man who guarded the door immediately closed the door mysteriously from the outside.

Everything seemed to be very important and needed to be kept secret, and the curiosity in Zheng Ya's heart suddenly rose to a new height.

Taking the key to open the door of the secret room mentioned by Mentor Xiaofei, Zheng Ya saw a toolbox made of cowhide about 1 meter high, half a foot wide, and a palm thick.

Visually, Zheng Ya felt that this thing was on his back, and it should be just right.

With a hint of excitement and expectation, Zheng Ya opened the toolbox.

As soon as the box was opened, Zheng Ya's face suddenly showed a very strange expression, these geological survey equipment prepared by Tutor Xiaofei are also too interesting, at first glance, it looks a bit like the regular configuration of the modern gold school captain that often appears!

A palm-sized compass!

This thing, it seems that the yin and yang and the old man in the hometown are often used, and they are used to using a compass to locate the method or to look at feng shui or something.

Unexpectedly, Mentor Xiaofei prepared a side for himself.

A one-meter-long sapper shovel.

This seems to be more like the standard configuration of tomb robbers, a sharp weapon for digging holes and mountains!

Zheng Ya was a little dumbfounded by the third thing, a red candle.

This thing actually made Mentor Xiaofei worry about passing it on to himself, well, as soon as this thing came out, Zheng Ya suddenly felt that he was labeled as a tomb robber.

Well, there is a story in Zheng Ya's hometown, before liberation, Xiangxi often stored some sweet potatoes, potatoes and other foods in the cellar, this kind of cellar has only one opening, usually when you want to take food, you will put the child in a basket.

The first thing I did was to light a red candle and place it in the southeast corner of the cellar.

The adults explained that when taking sweet potatoes, if the red candle is extinguished, no matter how many sweet potatoes you take, no matter how many sweet potatoes you still have, you have to leave immediately.

When I was a child, my grandparents talked about this rule, and Zheng Ya felt unclear.

Later, when I became sensible, Zheng Ya read a book called Ghost Blowing Out the Lamp Tomb Robbery, and what I said here is a bit infiltrating, saying that people light the lamp, and the ghost blows the lamp. Lighting candles in the tomb is a custom of touching the golden captain, but the origin is little known.

If the candle is blown out, it means that there is evil in the tomb and is harming, so you must escape from the tomb as quickly as possible, otherwise it will be a big problem.

Mentor Xiaofei actually passed a candle to himself!

Zheng Ya suddenly felt an evil spirit, he was a good young man of the motherland, he was admitted to the National University of Science and Technology, good guy, he actually met such a chattering mentor, Zheng Ya was also drunk.

Shaking his head speechlessly, Zheng Ya picked up the first secret treasure passed on to him by his mentor.

Compass!A commonly used equipment of the Yin Yang Qi Sect.

Also known as the compass, Luo Geng, compass disk, etc., is the predecessor of the modern compass, created from the era of Xuanyuan Yellow Emperor, after the generations of predecessors, according to the principle of the Book of Changes and Heluo, with reference to the principle of the sun, moon, five stars and seven politics and the operation of the stars and stars, observe the undulating form of the mountains and rivers on the earth, the plains, and improve the compass to determine the direction and survey the terrain.

Compass handed, seeing the words and uses on the compass, Zheng Ya couldn't help but be slightly stunned, on the side of the compass, there was a small instruction manual, Zheng Ya saw that the name on it was "500 Geophysical Prospecting Water Finder", not a compass.

Flipping through the manual, Zheng Ya saw it and said: "The multi-functional natural electric field geophysical detector completely solves the problem of the natural electric field source changing at any time, and at the same time integrates some of the essence of magnetotelluric sounding, MT, AMT, frequency sounding, and transient electromagnetic method, which has the characteristics of stable field source, high precision and high efficiency...... The function is to be able to probe all kinds of special magnetic fields, find special minerals, and find water sources......"

Seeing the explanation, Zheng Ya was a little embarrassed!

This thing is a high-tech product, and it's really not as superstitious as it looks on the outside!

Seeing this natural electric field geophysical detector, Zheng Ya felt that he had finally found the feeling of scientific research, and finally felt that he had joined a team of tomb robbers from an evil sect.

It's just that, looking at the compass in his hand, Zheng Ya suddenly found that the knowledge he had learned from Kanyushu, as well as some of the experience in Mengxi's writings, with this compass camouflaged geophysical prospector, it seemed that it could be verified in practice.

So, Zheng Ya was a little puzzled, was it a compass or a geophysical prospector that Mentor Xiaofei passed on to him?

The answer to this question may only be found in practice.

The first secret treasure was unexpected by Zheng Ya, it was not as simple as it seemed on the surface, and suddenly, Zheng Ya was also full of interest in the next two secret treasures.

As soon as his eyes lit up, Zheng Ya reached out and grabbed the sapper shovel.

It was cold to start, Zheng Ya lifted it up, and suddenly felt a shock in his heart, this shovel is too heavy, right?

The shovel, which is more than one meter long, looks inconspicuous, Zheng Ya just carelessly, casually mentioned it, but he couldn't lift it, and he added a lot of force to get it from the toolbox in front of him.

Similarly, this sapper shovel also has a small instruction manual, called titanium osmium alloy sapper shovel, weighing 80 kg, uses: burrowing, probing, protecting, climbing......

Here's how to use it: press 1 to make a hole, 2 to explore rock formations, 3 to protect a weapon, and 4 to climb......

Zheng Ya looked at this usage explanation and felt extremely weird, like this, as if he was making a phone query.

After thinking about it, Zheng Ya pressed the No. 2 button, and with a snort, the shovel in front of the sapper shovel began to change, and the shovel fell off several shovel heads, and a device similar to the Luoyang shovel appeared.

Curiosity suddenly rose, and Zheng Ya pressed the No. 3 button.

With a snort, the one-meter-long Luoyang shovel stretched out instantly.

What appeared in Zheng Ya's hand suddenly turned into a heavy alloy long stick, the head of the stick fell, Zheng Ya picked it up and took a look, and the part that fell turned into a peculiar short knife!

This is really a self-defense tool!

What is the number 4 key?
