This kind of tactics of digging tunnels to bury explosives and then come to the center to blossom has existed a long time ago, and this tactic even continued to the period of World War II, in the great counteroffensive in western Yunnan, in the face of the Japanese army's tightly defended Songshan Fortress, no matter whether the squadron used heavy artillery or aircraft to bomb indiscriminately. At the end of the reading, the Americans who accompanied him proposed a plan to dig tunnels, plant explosives in the lower part of the Matsuyama fortress, and then blast them in a directional manner. As for the final result. The squadron planted several tons of explosives under this fortress, and with a loud sound that shook the ground, this fortress that could not be blown up by artillery fire and smashed by planes was completely finished!

And this time the Chinese Army is repeating this process. However, one thing is better, the Huaxia Army has plenty of time to implement this plan, and the manpower and material resources in their hands are much stronger than those of the juniors of that plane. Since you have decided to do it, you must definitely play big. Based on daytime observations, as well as comparing real and false intelligence maps obtained through various means. In addition to the various "underground intelligence" of the sapper units gathered at night. "Nie Shicheng and the others finally have a little understanding of this underground behemoth...... I still don't know what it is behind the thick load-bearing walls to the ground, but at least I know where to put the explosives, and the approximate size of some of the buildings, etc., ..........

If you want to blow up a building, what's the best way to blow it up? Naturally, it is necessary to blow up the load-bearing structure of the building and choose the lowest possible position, so the Chinese army engineers chose to bury the explosives as much as possible in the underground of some buildings. But some building foundations are built so deep that it is difficult to dig so deep under existing conditions. So I had to give up. And as the line gradually lengthened, all kinds of problems came along. Problems with the ventilation of the underground works, the problem of the excavated mounds, and the problem of the quantity of work were combined with the fear that the Russians would find out. This series of contradictions forced the whole plan to be changed again and again.

But to this day. This plan is about to be completed after all, and the Chinese Army engineers have chosen a place that is most likely a warehouse to start! According to the observation during the day, during the fierce artillery battle during the day, many trucks entered and exited this area, so it is said that eighty percent of this place should be an ammunition depot. As soon as he thought of this, the major of the Huaxia Engineer in charge of this work couldn't help but feel a burst of excitement in his heart. A big one near the opponent's ammunition depot is so exciting!

They arrived near the target very early. Now all that is done is to expand the space to lay explosives. According to pre-estimates, at least 8 tons of explosives will be placed throughout the blasting. If all goes according to plan, the power of the explosives should be enough to blow up the building. And in order to ensure blasting efficiency. The sappers didn't pile up all the explosives in one place. Instead, they are placed separately in the individual sections. And in addition to this main goal. The Chinese Army also selected a number of other secondary targets and carried out blasting operations in the same way, but on a smaller scale. In the analysis of the Chinese Army, these places should be underground barracks or Yongdao ..........

Some people may ask, aren't they afraid that the Russians will find out about making holes with such fanfare all day long? To be honest, I was really afraid of being discovered, so after the engineer unit approached the target, the artillery of the Huaxia Army never stopped! Noise and smoke were used to mask the action underground, but it turned out that it didn't matter much. At first, the Russians did not expect that Huaxia would actually use this method to attack the city, after all, the northeast corner is surrounded by large and small swamps. It is said that it should not be possible to carry out underground construction. But isn't there a saying that you are not afraid of 10,000, but you are only afraid of what happens? The Siberian tundra is supposed to freeze quite hard in winter and basically cannot be dug up, and in summer, the thaw of the permafrost may wipe out the entire house, so the Russians generally lay the foundation quite strongly. …。

But there is a problem that this time the sappers dug a little deeper, already below the depth of the permafrost, and because of the weather, these places were not solid, so they finally dug under the Russian bunker. After the launch of the general offensive, the project of the Chinese Army was basically completed, and when the 12-inch heavy artillery slammed into the opponent's position, the Chinese Army had already begun to fill it with explosives!

"When will it be executed?" Nie Shicheng asked. "It's supposed to be tomorrow night, and it's almost finished filling up tonight." An officer next to him said. "Get ready tonight, then you can explode during the day tomorrow? Why do you have to wait a day? Nie Shicheng asked a little puzzled. If it explodes after dark, it is even more inconvenient for the other party to rescue it. The lethality will be greater. The officer thought for a moment and said with a dark belly..........

Minutes and seconds passed. The train artillery of the Chinese Army bombarded diligently for another day, basically bombing the entire Russian fortress group in the southeast again. And what frustrated the artillery officers and men was the ...... The highlight of the day was not their heavy artillery, but an explosion after months of diligent work by the sappers. Just this evening in the middle of the night, when people who are particularly safe, a earth-shaking explosion will be staged on the wasteland.

Rumble! Rumble! Rumble! Accompanied by a dull loud noise, even Nie Shicheng and the others, who were several kilometers away, could feel the continuous shaking of the ground under their feet, and huge fireballs suddenly appeared in the night in the distance, accompanied by a tsunami-like loud noise and explosion. A piece of ground protection in the distance suddenly collapsed! The whole process lasted less than a minute, and then fell silent.

"Huh? And that's the end of it? Nie Shicheng frowned and said, a plan that the sappers had spent months on was over? More than a dozen tons of explosives just to hear a sound? Nie Shicheng was a little disappointed. But just when he was a little depressed, suddenly fire dragons rose from the Russian fortress in the distance. Soon these fire dragons joined together, and a sea of fire formed in a short time, and the flames that rose into the sky even lit up the entire night! "What's going on? Didn't blow up to the ammunition depot, changed to fry the oil depot? Nie Shicheng was a little confused. But it looks like things are doing pretty well tonight. Nie Shicheng said in his heart..........

Because of the night, Nie Shicheng, who was several kilometers away, couldn't feel how strong the explosion was this time. But the Russian troops located in the Nebuchu fortress area really felt it, well, a considerable number of people hung up directly without even having a chance to feel it. What to say about the location of the blasting chosen by the Chinese Army is a bit biased, the ammunition depot was found, but only some of the explosives were planted. And according to post-mortem analysis, the part of the ammunition depot where the explosives were planted was still half empty! Therefore, although the explosion destroyed the load-bearing structure of the entire ammunition depot, it did not detonate more ammunition. However, even so, the entire ammunition depot was blown up, and a huge crater could be seen from the air.

In addition to the collapse of a large ammunition depot, the remaining explosives were placed in an area adjacent to the ammunition depot, which was also important and stored the oil used by the Russians to generate electricity. The Russians have a lot of coal, but it has a low combustion value and is expensive to ship. So after all that came to think about it, the Russians decided to use more efficient fuel to generate electricity, and it was easier to store. In order to ensure the safety of these oils, the Russians also put them in this storage area, which is not far from the ammunition depot, ..........

Some people may say that heavy oil doesn't fry? In fact, real heavy oil is difficult to ignite. Light fuel oil that has been smelted is more likely to burn and explode. So even if the explosives are blown up, the fuel does not necessarily have to be blown up. It is still very safe under normal circumstances. However, this time the Russians encountered an abnormal situation....... In addition, the Russians did die for some things. For example, the heavy oil in this warehouse is a heavy oil with good volatility. For example, the underground warehouse is well ventilated, and it is useless. …。

The violent explosion directly destroyed part of the load-bearing body of the oil depot, and after the destruction, it is impossible for the oil and gas not to spread under high temperature and high pressure, and the flame after the explosion is almost inevitable, and then the result is obvious, the oil depot is fried! And this is not an ordinary explosion, the heavy oil scorched by the high-temperature and high-pressure gas generated by the explosion quickly turns into steam and spreads to other areas along the corridors and pipelines everywhere, and the gas mixed with these air is easy to explode, and it can explode when it encounters a little spark. For example, sparks from the collision of iron objects, for example, sparks from static electricity, and these things can invisibly turn an area into a sea of fire.

This kind of arson speed is definitely not something that can be handled by Russian firefighters...... The underground roadway space is too narrow, all kinds of large fire-fighting equipment can't get in, and where to find so many fire extinguishing agents in a hurry? Coupled with the toxic gas produced by combustion, not to mention going in to extinguish the fire, even if people go in and walk out, the probability is not more than 2 percent. Plus these toxic gases don't know when they will explode! God knows what kind of results will be produced by the combustion of heavy oil when this oxygen is not sufficient..........

This free entry of oil vapor could pass through almost any of the Russians' defenses. Don't think about the general sealing door, the sealing tape can't withstand the burning of the flames at all, and it's only a matter of time before it's scrapped. As for the fire door similar to that on a battleship, forget it, the sealed door on a battleship is only responsible for a narrow passage, but if the fire door in the channel is thick enough and area, it will be heavy!

As a result, this fire was almost impossible to fight with manpower from the beginning, and the Russians who were originally in the tunnel didn't have to think about it. It must have all hung up. The Russian officers and soldiers who went in to rescue later hung up a few more times, and finally chose to give up rationally. There is only one last resort, which is to completely block all the waterways and vents, and the only thing left is to quickly extinguish the fires on the surface. And even this task is quite difficult to complete in the eyes of the Russian army, the Russian army is not less many, but fewer people who can be assigned to fight fires!
