The three of them continued to march eastward, the roadway was very wide, it seemed that four cars could be used in parallel, Tang Feng kept shining at the walls on both sides of the roadway and the top of his head, all of which were made of reinforced concrete, and in some places, the thick steel bars were even inserted straight out.

Han Jiang kept checking the drawing, although he didn't know Russian, he could still see a rough idea, and what he was worried about was not to make a difference, and there would be a fork in the road and unknown areas that were different from those on the drawing.

This time Han Jiang's worries were superfluous, they walked along the straight alleyway for more than twenty minutes, Tang Feng felt that the space in front of him suddenly opened up, he used a flashlight to shine, and another hall appeared in front of them, they walked into this hall, Tang Feng carefully compared the engineering drawing, "Yes, this is the second hall, this hall on the picture is like this, it is octagonal." ”

According to the engineering drawings, this second hall is in the middle of the whole bunker, and unlike the rectangular hall at the east and west ends, this hall is a regular octagonal shape, and in addition to the east and west sides of the connecting lane, two narrow corridors appear on the north and south sides of the octagonal hall.

Tang Feng walked ahead and entered the south corridor first, "This place looks exactly the same as the engineering drawing, and the function is the same." ”

The trio found that on either side of the hallway were twelve identical rooms lined up one after the other, "This is the dormitory. Han Jiang didn't look at the map, but he had already identified the purpose of this place.

"Of the twelve rooms indicated on the drawings, eight are sergeants' quarters and four are officers' quarters." Tang Feng identified the sergeant's dormitory and the officer's dormitory one by one according to the map.

The three of them carefully inspected each room, and the furnishings in each room were very simple, basically an iron bed, a table, a chair and a cupboard, and they couldn't see the difference between the officer's dormitory and the sergeant's dormitory.

Han Jiang opened the dusty drawers and cabinets one by one, but almost all of them were empty, and he couldn't see anything other than the thick dust.

After the three of them checked out the dormitories, they walked out with some disappointment, and Makarov suddenly thought of something, "Wait, I always think there is something wrong with these dormitories." ”

"What's the problem?" Han Jiang and Tang Feng were also surprised.

"The dormitory we looked at just now is similar to what we saw in the core area before, there is no decoration in the room at all, and the walls and roof are reinforced concrete, so there are people living in it."

"Yes, the core area is not decorated in place, so every room has not been put into use, and there is no decoration here, so let the officers and soldiers live in?" Han Jiang wondered.

"I think you're too worried, the conditions on the front line are difficult, so let's settle! Besides, you can see that although there are beds and furniture in the dormitory, there are no personal belongings, so from this point of view, it may have never been used. ”

Tang Feng's words made Han Jiang and Makarov temporarily agree with his point of view, and the three of them walked into the corridor north of the octagonal hall. ”

"It's really complete, life, entertainment is all there." Han Jiang sighed.

While talking, the three pushed the door and walked into a room, and there was a bronze plaque on the door of the room - "Gym". But what surprised Tang Feng and the three of them was that this gym was more like a boxing gym, with a standard boxing ring in the center of the room, around the boxing ring, there were some chairs lying horizontally and vertically, some dumbbells were neatly stacked in the corners, and there were more than a dozen barbells, and there was nothing else.

"Is this the gym?" Tang Feng looked at the scene in front of him in surprise.

"It's not difficult to understand that the people stationed here are all soldiers, so the fitness program is mainly weightlifting and fighting." Makarov explained.

The three of them arrived at the room with the bronze plaque of "Library", and Tang Feng approached the old portrait hanging on the wall, and he found that it was two dusty statues of Lenin and Brezhlev, which further proved the age of the bunker.

But to the surprise of the three of them, there were no books in the library, and there were even few bookshelves, but there were many desks and chairs. Han Jiang muttered.

"So it seems." Makarov said, walked out of the library, pushed open a door next to it, according to the drawings on the drawings, this should be a leisure room, or called a chess and card room, but at the moment there are only dusty tables and chairs, only a pool table lying quietly in the corner.

2

What gave Tang Feng and the three of them a headache was actually just beginning, and the changes in the first three rooms seemed to be within a reasonable range, but then, they saw more and more incredible things.

Tang Feng pushed open another door, only to see that the long table inside, full of broken or unbroken test tubes,*, Tang Feng remembered that there was no such laboratory on the engineering drawings, he hurriedly took a few steps back, and looked at the bronze medal at the door-bathroom.

Tang Feng couldn't believe his eyes until Makarov nodded, "Yes, this bronze plaque says - bathroom." ”

"How did the bathroom come to be like this?" Tang Feng hesitantly took out the engineering drawings and compared them again, and sure enough, the house on the engineering drawings was marked as "bathroom", and of course, the engineering drawings also carefully marked that there was a toilet here.

Tang Feng had the courage to walk up to those bottles and cans, "These things won't be poisonous, right?" Tang Feng looked at Han Jiang and asked.

"Hard to say! Be careful! ”

Hearing Han Jiang's words, Tang Feng's hand that was originally stretched out retracted again, Tang Feng looked up, he vaguely saw many water pipes, and even had a complete shower equipment above his head, "It seems that when it was built here, it was a bathroom!" ”

"But then it's weird?"

Han Jiang also approached those bottles and cans, he told Tang Feng to be careful, but he was quite confident, he picked up a good test tube and looked at it, there was a yellow mark on the wall of the test tube, obviously this test tube had been used, but they still couldn't tell what terrible substances were once contained in these test tubes.

Han Jiang gently put the test tube back in its place, and then, the three of them slowly withdrew from the room, and Tang Feng also deliberately closed the door with the bronze medal of "bathroom", as if he was afraid that something terrible in this room would leak out.

Next to the bathroom is the dining room and kitchen, and the three of them thought they would see rows of dining tables when they came in, but to their great surprise, they didn't see a single dining table in it, the innermost part of the room was the stove and stove, but the vast space outside, where it should have been a dining table, was empty, just no dining table installed.

Tang Feng turned around the restaurant suspiciously, although there was no fire here, he still vaguely smelled a smell, a strange smell, not the smell of oil smoke, nor the smell of vegetables, Tang Feng thought for a long time, only to realize that this smell was like a smell of blood!

But how can there be a smell of blood here? Tang Feng carefully shone the flashlight on the stove, and suddenly, Tang Feng's heart tightened, and the flashlight in his hand almost fell to the ground, because he saw a long splatter-like dark red blood stain appear on the white tile of the stove.

Tang Feng still couldn't believe it, approached the stove, and observed carefully, "This ...... It looks like there was a terrible fight here! ”

Han Jiang also saw the blood stains on the tiles, "The splattery of blood indicates that the deceased was stabbed with a knife or dagger, and then the wound was spattered, but Tang Feng, you first have to figure out whether this is human or something else's blood!" ”

"Isn't it human?"

"Do you see the dead body?"

"Nope!" Tang Feng shook his head.

"I don't think it's human blood!" Han Jiang slowly touched the blood stains on the tiles with his hands.

"How so?"

"I can't say it yet, just with my years of experience."

Tang Feng wanted to say something, but Makarov suddenly beckoned them over, and the two walked to Makarov's side, Makarov pointed to the coffee-colored ground and said, "There are blood stains here, too." ”

"Ahh......h And there was more than one, Han Jiang found a spray of blood at the root of another wall, "This ...... What's really going on here? So much blood? Tang Feng stood in the middle of the room, staring at the blood on the ground in a daze, and he shuddered.

Han Jiang was also puzzled, but he insisted that these bloodstains were not human bloodstains, but some animal bloodstains, and Makarov was also inclined to his opinion, but they still couldn't explain where the bloodstains of so many animals came from?

Tang Feng was obviously quite frightened in the cafeteria, and when he followed Han Jiang and Makarov into the infirmary, he instinctively became alert, for fear that it was also covered with blood like the restaurant, and it was human blood.

But the infirmary was very tidy, and there were no items that did not fit the environment here, everything was like a normal infirmary, and many medical equipment were still in place, but everything was covered with a thick layer of dust.

"It seems normal here, it's just an infirmary." Tang Feng said, he had already walked to the end of the infirmary, he found that there was another door here, there was a lot of dust on the door, but the door was not locked, it was hidden, Tang Feng gently pushed, the door opened, and it was a small black room inside, Tang Feng felt that it was cold and abnormal, and his flashlight swept to a row of cabinets, which shone with a strange metallic luster in the dim light.

Tang Feng was a little scared, took two steps back, but leaned on Han Jiang, "What are you retreating?" ”

"You...... You see what that is? Tang Feng's voice trembled a little.

Han Jiang stepped forward and carefully took a look at the thing with a flashlight, "What's there to be afraid of, is this a freezer?" Or call it a refrigerator. ”

"You might as well say it's a morgue!" Tang Feng had already realized what those cabinets were.

Makarov also said, "Yes, this thing is very similar to the morgue in the 60s and 70s of the last century, and we used to deal with these things a lot. ”

"Old Ma, why do you want this thing in this place? Didn't we judge that it had never really been put into use? ”

Makarov thought for a moment, "There are many other places that are not in use, but they are used here, and although the dormitories are not renovated, they are also occupied, and I guess these are for the workers who built Bunker 21." ”

"You're saying everything in this infirmary was for construction workers at the time?"

"yes, so you see that the infirmary here is quite rudimentary!"

"And these morgues, too?"

"Well, when building this kind of project, it's still easy for someone to have an accident."

Han Jiang was noncommittal about Makarov's inference, and the three of them felt depressed about staying here, so they hurried back to the hexagonal hall.

Tang Feng spread out the engineering drawings, "I've seen the living area, there is only the security area below, it looks like there are several warehouses, I don't know where to find anything?" ”

"I thought I would find the most valuable clues in the living quarters, but now I'm disappointed. So I don't have much hope for the security zone either. Han Jiang said.

"Han Jiang, Tang Feng, have you found it, the design of the entire bunker is very reasonable, the living area is arranged in the middle, in case of emergency, the officers and soldiers stationed here can feel the core area and the support area at both ends as quickly as possible." Makarov said as he stood in the center of the hexagonal hall.

Tang Feng looked at the dark lanes on both sides, "Don't sigh at the design first, we have to quickly finish surveying the security area, Yelena and Liang Yuan are waiting on it." ”

After Tang Feng's reminder, the three of them were silent and plunged into the dark alleyway leading to Hall No. 3.

4

In exactly the same environment, the same distance as the previous section of the alley, and the three of them soon came to Hall 3. Hall 3 is rectangular in shape, like Hall 1, with two large doors on the north wall and three large doors on the south wall.

Tang Feng first found the location of the power distribution center, the door of the power distribution center was closed, and the other four doors were more or less left gaps below, Tang Feng looked at Han Jiang, Han Jiang looked at Makarov, and the three of them were wondering if there would be something that shouldn't appear here, such as people!

Tang Feng followed the marks on the engineering drawings and found the arsenal first, and under the shutter door of the arsenal was a crack that allowed one person to bend down to enter. The three mermaids rushed in, and the space inside surprised Tang Feng, "It seems that I misunderstood, this is not just a place for guns and ammunition, but a warehouse for storing large weapons." ”

"yes, that's enough space for eight to ten main battle tanks." Makarov sighed.

"Guys, don't be amazed, there's nothing here right now, and you expect us to be able to drive the tank out." Han Jiang said, walking straight to the corner of the arsenal.

Tang Feng and Makarov also followed, because they found that in the empty arsenal, only in that corner were a dozen wooden boxes neatly stacked.

Han Jiang didn't think about it, he directly opened the long wooden box above, which was full of guns, Han Jiang opened several wooden boxes one after another, and the six boxes in a row were full of assault rifles, including AK-47, AKM, and a box of brand-new AK-74, Han Jiang was happy, "Old Ma, Tang Feng, I have a hunch that I am going to send it today." ”

After Han Jiang finished speaking, he opened the next box again, full of a box of TT-33 pistols, and then a box of *, the bottom three boxes are three boxes of bullets, two boxes of 7.62mm, and the other box is 5.45mm, Han Jiang has not touched a gun for a long time, and when he saw so many guns at once, he couldn't wait to load the bullets and try it immediately.

Han Jiang took out a TT-33 and threw it to Tang Feng, and then prepared to load the bullet, but while Han Jiang was loading the bullet, he felt that there seemed to be something strange in the box containing the TT-33 pistol, Han Jiang reached in and touched it, as if there was a mezzanine underneath, Tang Feng also noticed it, Han Jiang suddenly ripped open the mezzanine, and two brand-new * appeared underneath, as well as two small dagger guns.

Han Jiang and Tang Feng were surprised, and Makarov recognized the models of the two guns at a glance, "S4M 7.62mm* and NRS-2 Whispering Dagger Gun." ”

Han Jiang was not interested in this kind of small pistol, Tang Feng picked it up, "This is too small, it can be used for Liang Yuan to defend himself." ”

"Yes, it's very small, these two guns are only used by spies or special forces, and they were mainly equipped with the KGB and the Ministry of Internal Affairs before, so it's not normal for this gun to appear here!" Makarov saw the clues from these guns.

"How is it not normal?" Tang Feng asked.

"There are two abnormalities in this batch of guns, one is the guns used by these two agents, which are generally not used by the military, how can there be here?" Makarov thought for a moment and continued, "There are also the boxes of assault rifles above, AK-47 was equipped with troops in the forties and fifties, AKM assault rifles were equipped with troops in the late fifties, and it is normal for these two guns to appear here, but it is not normal for this box of brand-new AK-74 to appear here." ”

"Why?" Tang Feng was puzzled.

"Because the AK-74 5.45mm assault rifle began to be equipped with the Soviet army in 1974." Without waiting for Makarov to answer, Han Jiang had already told the reason.

"yes, that's why I said it's strange that the AK-74 is here! By the time I left the forward base, there was no such gun equipped, the bunker here was built in the sixties, how could such a gun be here......" Makarov became quieter and quieter the more he spoke, and finally completely fell into muttering.

The three of them each picked out their weapons, came out of the arsenal, and got into a huge space, according to the indication on the engineering drawings, this is the oil warehouse, but the three of them went around the entire warehouse, but they didn't find a trace of oil here, not even the smell of gasoline.

"Looks like it's never been used here." Tang Feng Road.

"No, quite the opposite, it was used, but not as an oil storehouse, but as a shooting range." Han Jiang walked to the farthest wall and ripped off a piece of target paper from it.

Although the target paper has long been yellow and worn, the bullet holes on it are clear, and it is a full ring that almost all hit the bull's-eye, "It seems that this is a master's achievement!" Makarov said.

"Then it's all the masters." Han Jiang took off two more target papers from the wall, and again, they were all full of rings, Makarov was a little shocked, and Han Jiang asked Makarov in words, "Old Ma, when you see this target paper, you don't have any ideas?" ”

"Han, don't you just want to say that these students are fighting?"

"Who else but them? Hit so many full rings! Han Jiang raised his voice.

"Perhaps...... Perhaps it was after Buldenko came to the forward base that he discovered this huge bunker, so he used the bunker to train the cadets, which is also a matter of common sense. Tang Feng speculated.

Han Jiang stood in front of the huge wall and thought quietly, "This assumption can be established, but why didn't Bultenko tell Lao Ma about such a big matter?" Is this normal? ”

There was silence in the huge oil warehouse, a terrible silence, and all three of them wanted to get rid of it quickly, so they walked out quickly.

Next is the ammunition depot, there is no ammunition in the ammunition depot, but the situation inside frightened Tang Feng and the three of them, only to see that the ammunition depot is full of holes, the four walls, the ground, the roof, there is hardly an inch intact, the ground is full of large and small gravel, people can't stand on it at all.

The three of them had to stand by the door, "It looks like there's been a big explosion here!" Tang Feng said.

"The Big Bang? Ammunition depot explosion? Han Jiang's eyes suddenly turned into a sea of fire.

"Maybe this explosion is the reason for the abandonment of Bunker 21." Makarov tract.

"I don't think it's that simple, if there really is a big explosion here, then the whole fortification will be destroyed, but now we see that the rest of the bunker is intact, only here there was an explosion, make it look like this, do you think it is better to abandon this bunker because of the explosion of the ammunition depot?"

Han Jiang's words left Makarov and Tang Feng speechless, Tang Feng held back for a long time and asked, "Then what do you say is going on?" ”

Han Jiang stared at the explosion scene in front of him for a long time, and finally shook his head, "I don't know, where to go next?" Han Jiang asked Tang Feng instead.

Tang Feng checked the engineering drawings, "There is only one place left, and the engineering drawings indicate that this place is a maintenance workshop, and it is estimated that it is a car repair shop!" ”

Sure enough, as Tang Feng expected, although there was not a single car in the maintenance workshop, a large number of auto parts were piled up on the ground in the corner, the engine oil on the ground had already solidified, and tools such as wrenches were scattered all over the place, "It seems that this is a car repair shop, and it is estimated that it can also repair tanks, armored vehicles and the like." ”

"Look carefully and see what you can find." Han Jiang still didn't give up.

But the three of them searched the entire maintenance workshop, except for the car repair tools, they only saw spare parts, but when the three of them were disappointed, Han Jiang suddenly found something strange on the innermost wall of the maintenance workshop.

Tang Feng and Makarov surrounded the past, Tang Feng used a strong flashlight to illuminate this wall little by little, suddenly, Han Jiang pointed to Tang Feng in front of him, under the illumination of the strong flashlight, Tang Feng vaguely saw the straight gap in the wall, he knew that this was another door, a hidden secret door.

6

Tang Feng and Makarov stood on both sides of the door, Han Jiang raised his gun to face the secret door in front of him, the three of them glanced at each other, Han Jiang raised his gun to the door lock of the secret door is two shots, and then kicked the door suddenly, the three of them dodged in, the pitch-black hut in the huge bunker, so quiet that you could hear everyone's heartbeat, half a minute later, when everyone's eyes adjusted to the darkness in the hut, Han Jiang was sure that there was no one else in the hut, so he pushed the flashlight.

This is a cottage of only ten square meters, a single bed leaning against the wall, there is a table next to the bed, there is a chair in front of the table, and there is a bookcase on the wall at the foot of the bed, Tang Feng looked up at the roof, there was only an incandescent lamp, all of this was full of dust, Han Jiang carefully checked the ground, a layer of fine and uniform dust, no footprints were found, obviously no one has been here for a long time.

Han Jiang and Tang Feng both put down the guns in their hands, but Makarov was still holding the gun, staring nervously at the four walls, and the posture seemed to be afraid that someone would pass through the hard reinforced concrete wall and shoot at him!

"Old horse, what are you looking at?" Han Jiang asked with concern.

"No, I didn't look at anything." Makarov's voice was low.

"Then why do you look like this?"

"Because...... Because it suddenly gave me a special feeling. ”

"Special feelings?"

"Yes, I don't know. Maybe...... Maybe this is the last room in the bunker, and I think it's time for us to discover something here. Makarov slowly lowered his arm with the gun.

"Found something?" Han Jiang looked around, "What can you find here?" I don't think it's much like the dormitories in the living quarters. ”

"Maybe the problem is in the living quarters, but this room is here." Makarov whispered.

"So you feel special? Hehe, maybe it's a rest room for repair shop workers, or a duty room. Han Jiang guessed.

"I hope so." Makarov muttered.

Tang Feng walked to the table and pulled the table drawer, he found that all the drawers of this table were locked, but they were not locked, Tang Feng opened each drawer one by one, which was full of some broken newspapers and dozens of unused stationery.

Tang Feng didn't find anything in these shredded newspapers and stationery, "This room is indeed very different from the dormitories in the living area, there are almost no relics left in the dormitories in the living area, but there are still some here." ”

"What did you find?" Han Jiang asked.

"No, just shredded newspapers and stationery." Tang Feng turned around and walked to the bookcase, "Also, there is one more bookcase here than those dormitories." ”

As he spoke, Tang Feng casually picked up a book in the bookcase, the book was covered with thick dust, this is a Russian book, the title of the book is "Blasting Technology and Engineering", Tang Feng flipped through it, this is just a technical book, there is nothing special.

Tang Feng handed the book to Han Jiang, but Han Jiang saw some fame from it, "This book has been turned over, it seems that the people who read this book know it well." ”

"Yes! There are also a lot of red pen marks in the book. Tang Feng said and picked up another book, which was an English book, "The CIA Secret Service Handbook?" Tang Feng slowly read out the title of the book.

"The Secret History of the CIA." Tang Feng picked up another book, also in English.

"It seems like most of the books here are in English." Han Jiang also felt something different.

"Yes, the two rows on the top of the bookcase are full of English novels, including Poe's, Hemingway's, Salinger's, Jack London, Mark Twain, ......"

Tang Feng said, he had already removed a small half of the books on the second row of bookshelves, Tang Feng suddenly felt that there seemed to be space inside, he poked the flashlight in, and sure enough, a big book was faintly revealed in the second row of bookshelves, no, it was more like a folder! Tang Feng reached out and pulled the folder out.

7

Tang Feng opened the folder, and there was a thick pile of documents inside, Tang Feng spread the pile of documents on the table, and Han Jiang and Makarov also gathered around, "It's all Russian documents." Tang Feng preliminarily judged.

"And most of them are KGB documents." Makarov judged further.

"KGB documents? It seems that there is a lot of fame in this. Han Jiang came to the spirit, but he didn't know Russian, so he could only wait for the results of Tang Feng and Makarov.

Tang Feng and Makarov quickly flipped through the documents separately, and Tang Feng quickly turned out an important document, "This may be a document that can unlock the secrets of the bunker." ”

"Oh! Translate it quickly. Han Jiang urged.

So, Tang Feng slowly translated this document:

Order of the National Security Council on the construction of permanent fortifications on the Soviet-Chinese, Mongolian-Chinese borders

(Vladivostok Project)

Special Engineering Directorate of the State Security Committee (13th Directorate) Я19660823

China has already exploded* in 1964 and conducted another thermonuclear test on May 9 this year, and has effectively become a nuclear power, and it is believed that China will soon master * and nuclear technology. Therefore, on the orders of the Central Committee of the CPSU, in order to prepare for a possible war with China at any time, the Special Engineering Bureau (13th Bureau) of the Special State Security Committee began construction of complete permanent large-scale fortifications on the border between Mongolia and China.

The fortification should have the following capabilities:

1. It is necessary to have the ability to defend against nuclear weapons, biological weapons, and chemical weapons attacks (specific parameters have a detailed task book)

2. It needs to be extremely concealed and not easy to be detected, in order to achieve the purpose of the suddenness of the battle (the specific site selection has a detailed task book)

3. There needs to be sufficient space to station a certain scale of armed forces in the fortifications (the specific scale has a detailed mission book)

4. It is necessary to have complete living facilities for a certain scale of armed forces to live here (specific facilities have a detailed mission book)

5. It needs to have complete communication and command capabilities, and can become a regional command and communication center in wartime, and can be connected and compatible with the command system at all levels of the headquarters, military regions and the front line (specific parameters and equipment have a detailed task book)

6. It is necessary to have certain electronic detection and intelligence collection capabilities, and develop the fortifications into the most cutting-edge intelligence collection center in wartime (specific parameters and plans have detailed mission statements)

7. It is necessary to have a certain conventional air defense capability (specific parameters have a detailed task book)

8. It is necessary to have a strong ability to support stamina, supply and supply front-line troops in wartime, and have strong self-sustaining ability (specific facility data have a detailed task book)

9. It is necessary to have the necessary conditions for wartime field hospitals to provide basic and primary medical support for wartime wounded officers and soldiers (specific facility data have a detailed task book)

August 23, 1966

After Tang Feng finished translating, Han Jiang and Makarov both fell into deep thought, and Tang Feng was also thinking back to the experience from the discovery of the bunker to the present, and kept recalling the word "Vladivostok Project...... Vladivostok Engineering ...... Conquer the East, what a big breath! It seems that this bunker was built during the Cold War to prepare for a nuclear war with China. ”

Makarov was repeatedly staring at the "Special Engineering Bureau of the National Security Council (13th Bureau)", Makarov wiped the Arabic numeral "13th Bureau" with his fingers, and after making sure that he was right, Makarov finally shouted, "I finally found this 13th Bureau." ”

"The thirteenth round of the KGB? Is that the thirteenth inning you never knew about? Tang Feng asked rhetorically.

"Yes, I didn't know what the KGB was doing in the thirteenth round? It is not even clear whether it existed, and I did not expect it to appear on such a document. Makarov looked excited.

"Special Engineering Directorate of the National Security Council?" Tang Feng read the name again, "It seems that this is the full name of the Thirteenth Bureau." Special Engineering Bureau? What is this for? ”

"I don't know, but from this document, it's clear that this sturdy bunker was built by the Thirteenth Bureau." Makarov tract.

"The KGB is still in charge of engineering?" Tang Feng asked.

"Yes, there are some construction projects in the KGB that involve important targets and state secrets, and it is not appropriate for ordinary construction companies to undertake them, so now it seems that the 13th Bureau has undertaken this task."

"But didn't you say that the thirteenth round existed for a short time?"

"Yes, judging from this document, the Thirteenth Bureau existed in the sixties, but it should have been canceled later, so few people know about it." Makarov reasoned.

"It seems that this is an extremely important project." Tang Feng looked around the huge sturdy bunker again.

"Judging from this order, in the Soviet-Chinese and Mongolian-Chinese borders, there should be dozens of similar bunkers, the situation was very tense at that time, and the two countries were ready to fight a nuclear war at any time, so they secretly built such a huge, so strong, and can prevent nuclear, biological and chemical weapons attacks, I think on the one hand, because the project is important, on the other hand, because this project needs to be kept secret, so this task was handed over to the KGB to complete." Makarov further deduced.

"But why is this large bunker abandoned before it has been opened?" Tang Feng stopped Makarov with a word, and at this time, Han Jiang, who had been silent, suddenly spoke, "This is to ask the Brtenko who stayed in the thirteenth game." ”
