Next, the 101 Institute led by Xia Qiu began their research work, they established a forward camp near the ancient city, and some soldiers and the people of the 101 Institute lived in the advance camp of the ancient city, they worked day and night, as if they were looking for something.

Zhang Bin and Zhao Gang always discussed in private, they didn't know what the 101 Institute was looking for, but the organization ordered them not to ask, so they never thought about it, to understand the purpose of the 101 Institute and the group, just to ensure their safety step by step and assist them in doing some work.

The days passed, and in the blink of an eye, they had been in the mountains for 1 month, but the progress seemed to be very slow, and the people of the 101 Institute turned the ancient city upside down, but it seemed that they had found nothing.

But suddenly one day, Zhao Gang received a message from the advance camp at the base, saying that the 101 Institute led by Xia Qiu finally found what they were looking for, it was a tunnel, and named Tunnel 2, Xia Qiu was very excited that day, he led the people who went to the camp and returned to the base again.

This night, he asked Jiang Ji for some local barley wine for the first time, drank a lot, and seemed even happier than the last time, after he was a little drunk, he talked to Zhao Gang and Zhang Bin about the purpose of the 101 Institute this time, but it was only a simple disclosure of some information.

According to him, they didn't know what they were looking for when they came in this time, but the purpose of their entry was to find out what was here, what was it that made the aerial photos of this area completely white and overexposed, and the entire area could not be effectively imaged.

It turned out that since 80 years, the state has carried out aerial photography and mapping of uninhabited areas within the territory, and when the plane passed here, it took a set of topographic photos, but when I went back, I found that there was an area in the Gaoligong Mountains in this area, and there was an area where the shooting was overexposed.

So the second time to reshoot, but found that it was still in the same area, still unable to effectively image, which attracted the attention of the relevant departments, at that time there were two speculations, one is the conspiracy theory, that is, to assume that there is a reactionary force here, they through some means, resulting in the inability to take aerial photos, which at that time actually did not have this technology, but for national security considerations, this statement was also adopted; The second theory is to explain this matter in a more scientific way, that is, there is an unknown radioactive source here, which emits some kind of high-energy rays that cannot be seen by the naked eye, which leads to overexposure of the negative, which has a certain scientific theoretical basis, so it has also been adopted.

In order to find out about this matter, the 101 Geological Research Institute and an army were sent to assist them in entering this area to conduct a detailed study here, hoping to find out the root cause of this phenomenon, which is of certain significance to future military counter-reconnaissance technology.

Only then did Zhao Gang and Zhang Bin know the reason why they came here from the 101 Institute, but they didn't quite understand why Xia Qiu was so happy today.

Xia Qiu said to them again, they found the No. 2 tunnel today, the radiation value in it is very high, but it is different from the previous nuclear radiation, after testing, they found that this radiation is very close to a certain magnetic field, and this radiation is basically harmless to the human body, in other words, this kind of radiation in the whole world, should be found for the first time.

Xia Qiu's words are only said here, and he won't say much about them any further, this is actually beyond his principles for a long time, and he only said so much to these two people because he was excited, because he was happy, and because he drank some wine.

But even if he said so much, the political commissar of the 8th company, Zhao Gang and the company commander Zhang Bin, were still confused, they were at most two soldiers, how could they understand it, Zhao Gang just recorded what he said in his diary.

The next day, Xia Qiu and Company Commander Zhang led a part of the people to the ancient city again, and in the base, only Zhao Gang and some soldiers were left.

About at night, Xia Qiu and some people entered the No. 2 tunnel, according to the telegram returning from the camp ahead, 7 people from the 101 Institute, and Zhang Company Commander entered the tunnel with 30 soldiers, and more than 20 soldiers were left outside the tunnel, ready to be on standby at any time to deal with emergencies.

Zhao Gang was very worried about the situation ahead, and he had to contact the radio from time to time, but the answer he got was that there was still no news in Tunnel 2.

In the early morning of the next day, when Zhao Gang was still sleeping in the barracks, suddenly the confidential officer ran in and woke Zhao Gang up.

Sure enough, when he came to the radio, there was a burst of fierce gunfire from the microphone, Zhao Gang hurriedly asked about the situation, the operator in front shouted loudly, and many comrades suddenly ran out of the No. 2 tunnel, they all seemed to be crazy, they bit when they saw someone, and they couldn't be killed with a gun, and they needed emergency support.

Zhao Gang's cold sweat had already come down, and he didn't know what was going on in front of him, how could there be such a situation.

So he hurriedly gathered the troops, gathered the remaining 60 people, and rushed to the mountain, but the deputy company commander with him reminded Zhao Gang that he hoped that he could stay at the base, after all, Zhao Gang was a political commissar and should have been in the base to sit in battle, because the current situation in front is unknown, and Company Commander Zhang can no longer be contacted.

Zhao Gang gritted his teeth and nodded in agreement with this suggestion.

So he stayed in the camp with only a few soldiers from the guard squad, and everyone sat by the radio station, constantly calling out to the comrades in front.

However, the deputy company commander led people to support, but there was no news from them, and by noon the next day, there was not a single radio contact.

Zhao Gang thought of the seriousness of the problem, he ordered the confidential personnel to immediately send a telegram to the superiors to report briefly, but did not get any response, so Zhao Gang weighed the pros and cons, and finally asked the guard squad to bring equipment and go up the mountain into the ancient city with him, hoping to do the last support.

But just when everyone was about to leave, the camp was also attacked unexpectedly, he saw a comrade, like a madman, running from the mountain into the base, a little soldier of the guard squad did not react, he was pressed to the ground by the comrade like a madman, biting open the throat, the little soldier immediately fell into a pool of blood, convulsions and died.

At this time, Zhao just gave an order, picked up a gun and fired at the comrade who entered the base, but this could only slow down his movement, but it could not completely kill him.

Zhao Gang never dreamed that such a terrifying thing would happen in broad daylight at noon, it was simply a nightmare, but the nightmare had just begun.
