With the active support of Hong Xuezhi, tens of thousands of sappers along the railway line were busy, from the banks of the Yalu River to the front line of Kaesong, there were sappers building anti-air fortifications everywhere along the way, and the American planes still came to make trouble from time to time, but it did not lower the morale of the sappers, because everyone knows that only by repairing the anti-air fortifications can they be saved from bombing, so they are all in full swing along the way.

"It's not enough!" Bangs looked at his arrangement of the artillery and muttered to himself. "You can't put an anti-aircraft gun on every inch of the railway line!" Su Huizhen came over and said. "I didn't want to reach that state either, I just wanted to make the most reasonable arrangement!" Liu Hai said: "In fact, it is enough to place an anti-aircraft fire network with low, medium and high in each important area, and as for those stations, it can be appropriately arranged less!" For example, the important bridges and sections of the Nameless River and the Qingchuan River need a little more, although the station has a lot of materials, but it is very hidden, and Americans often can't find it when they want to find it, well, yes, that's it! Bangs said as he drew on the map.

"You've done a good job, dear Hai, you don't need to be too yourself!" Su Hye-jin put her hand on the shoulder of Bangs. "It's not impossible! Every * of the enemy plane will kill people, when will we be like the big brother of the Soviet Union and have a powerful air force, then I will not have to bother so much! As soon as Liu Hai finished speaking, the communication soldier ran in. Report, Division Commander Liu, this is the latest report on the enemy situation, and the minister asked me to send you a copy! "Okay, I'll see!" Bangs took it and looked at it. "This Van Vliet is going to have a good fight with us!" Liu Hai handed over the enemy report to Su Huizhen!

"The Americans are concentrating more than 2,000 planes to fight a strangulation war?" Su Huizhen said in surprise while watching. "Yes, this time we are going to have a game with Van Vliet, you, an expert, will go with me tomorrow to inspect and guide along the railway line, and we must establish an effective air defense system in the shortest possible time" Liu Hai said this, looked at the 400-kilometer-long supply line on the map, and added three more words, "Relative!" "In fact, the Americans don't have so many tricks to bomb, just those few points and transportation hubs, and it is impossible for them to throw their planes along the railway line!" Su Huizhen said. "yes, so we still have a way!" Bangs stood up and stretched out his arms.

"Minister Hong, do you think you can build a few more underwater bridges in some rivers along the highway that are not too turbulent, and let the bridges on the river be used as bait?" Bangs said. "I have had this idea of yours, but the rivers from North Korea are very urgent, and it is not easy to build an underwater bridge, but now that the enemy is currently in power, it is better to do something special, I have already informed Chairman Kim about this matter, let him do it, and he has agreed!" Minister Hong said. "Since this is the case, I don't have to worry about it, starting tomorrow, I will work with Comrade Su Huizhen along the railway line to inspect and guide the construction of air defense facilities along the way, I think this batch of anti-aircraft artillery can be put into battle as soon as possible!" Bangs said. "Yes, yes, that's what I mean! With you, the cannon god, and Su Huizhen, a mechanical expert, together, you will definitely be able to get twice the result with half the effort! Hong Xuezhi said happily.

Early the next morning, Liu Hai called Su Huizhen to start the core inspection, and when they arrived in Pyongyang, Liu Hai found that the most heavily defended place in the entire Pyongyang city was not the munitions warehouse and residential areas, but the official residence of the golden fat man! "This golden fat man must have seized the anti-aircraft gun of Nanyun!" Bangs are simply out of breath, this fat blonde man has nothing to say! Liu Hai took Su Huizhen and walked straight to the mansion and asked to see the golden fat man! At first, the sentry was still pushing, but after Su Huizhen told him that he was the secretary to the head of the Soviet military delegation, the sentry immediately ran in to report. Su Huizhen said it very casually, scared the golden fat man half to death, and ran out.

"Chairman Kim, is your official residence too nervous about air defense arrangements?" Liu Hai asked directly. "Did you intercept the anti-aircraft artillery of the southern transport without authorization?" "What's the situation? I don't know! "The golden fat man's eyes flickered!" Chairman Kim, hundreds of thousands of soldiers on the front line are starving and cold, and they urgently need anti-aircraft weapons to establish an effective transportation line-to-air defense network, but there are 20 anti-aircraft guns arranged around one of your small official residences. Bangs said. Chairman Kim, on behalf of the Soviet Union, I am ashamed of your behavior, and if you insist on doing so, I will report the situation to Moscow! Su Huizhen said angrily. Don't don't, this is a misunderstanding, don't be nervous, I really don't know the situation, I'll immediately ask someone to send all the anti-aircraft guns south! The golden fat man hurriedly said.

Liu Hai naturally didn't believe what this fat man said, he took Su Huizhen to watch all the anti-aircraft guns around the mansion be transported to the station, and after getting on the train, he went south with Liu Hai! "My dear, people are also the head of state, why didn't you leave anyone behind?" Su Huizhen remembered that when the anti-aircraft gun was pulled away, the golden fat man's expression of eating made her want to laugh. "This fat golden man, greedy for life and afraid of death, always wants to use us as cannon fodder, the North Korean people are just blind and have found such a fool to be the head of state!" Liu Hai scolded, "Last time, if he hadn't left the battlefield without asking for instructions, our losses would not have been so big, and now I dare to do this, I think Mr. Peng's two slaps are still not hard enough, reflect with Mr. Peng, let Wu Fat Man fight next time, and promise to let him remember it once!" "There's no way, only he can mobilize the power of North Korea now, and it can't be replaced by another person, the cannon has been pulled down, don't be angry!" Su Huizhen said.

The next two people went to the Jinchuan River, here is the first bridge to the south, and it is also a very important bridge, after observation, Liu Hai felt that the air fortifications here are still okay, but there are only two medium anti-aircraft guns, although the low-altitude blockade is enough, but the high-altitude strike force is still not enough, Liu Haijiang brought two medium guns from the golden fat man are placed here, and Liu Hai personally observed and decided the place to put them! When leaving, Liu Hai felt that the air defense settings here were almost the same, especially after the addition of two medium air defense guns, the entire air defense surface increased a lot, as long as it was not a cluster of hundreds of aircraft concentrated bombing, it should be able to deal with it, after all, the airspace here is only so big!

Go further down to the Qingchuan River Bridge, although there is an underwater bridge here as a backup, but this underwater bridge can not take the railway, so the Qingchuan River Bridge is a very important bridge on the entire transportation line! Liu Hai took a look at the defense around the bridge, and a certain amount of anti-aircraft fire had been arranged on the mountains on both sides, but the width of the Qingchuan River, there was a defensive gap in the middle part. "You can also use the method of building pontoon bridges to arrange some anti-aircraft firepower in the middle of the river, as long as you have some small-caliber blockade firepower, at least you can't let enemy planes have loopholes to exploit! Building a pontoon bridge can also add a passage across the river, and it can also disperse part of the enemy's firepower! Bangs said. Yes! The commander of the air defense battalion of the Qingchuan River patted his head, "I have always wanted to fill this defensive gap, but I have never been able to think of a way, I didn't expect it to be so simple, and it is not very difficult to build a pontoon bridge!" Thank you, Chief, now I will be more confident in protecting the Qingchuan River Bridge! "Okay, hurry up, I'll leave you five small-caliber anti-aircraft guns!" Bangs said. "Okay, okay! Five doors are enough! "The commander of the anti-aircraft battalion repeatedly expressed his gratitude!

"There's the Nameless River ahead!" Su Huizhen said. "The nameless river is the top priority, and it is also the throat of the entire triangle, and I want to take a good look at the air defense settings here," Liu Hai said. After arriving at the Nameless River, Liu Hai found that there was only a small team of air defense troops here. The frightened Liu Hai hurriedly called the company commander Guo Tie here. "Division Commander Liu, we are also eagerly looking forward to increasing our anti-aircraft firepower, but our hilltop here is narrow, and we can't put down more anti-aircraft guns, so we are also helpless!" Company Commander Guo Tie said. Liu Hai looked left and right up and down, and found that Company Commander Guo Tie was not wrong, the mountain here is not only steep, but also the mountain is basically a vertical mountain wall, there is indeed not much place to place, if it is placed under the bridge, it will delay and block the construction site, and it is easy to be destroyed!

"In this way, you should enlarge the openings of the caves on both sides and place two medium-caliber anti-aircraft guns on both sides of the caves, which will not only facilitate concealment, but also be able to hit enemy planes, so that enemy planes will have some scruples when diving and bombing! In addition, the hill on the left is in a very good geographical location, if the enemy plane wants to bomb, it must be in the air to bypass the mountain, you can put two more anti-aircraft guns on the back of the mountain, give them a surprise, although I am not a pilot, but I also know that when the enemy plane is attacking the bridge, it is not possible to attack anywhere, even if it is a special attack, there is a possibility that it will not be able to pull up in time and hit the mountain! "After walking around the bridge, Bang Hai put forward his opinion!" Don't say it, that's really the case! The battalion commander of the People's Army, who was in charge of the air defense mission of the Nameless River Bridge, said as if he had been enlightened: "I will start arranging it immediately!" "I'll give you two more medium guns and four light guns, and one heavy gun, the nameless river is the throat area, and you must ensure maximum safety!" Bangs said. "Please rest assured, with your guidance and help, I will definitely do my best!"

Liu Hai and Su Huizhen inspected and guided from north to south, line by line, point by point, and distributed all the anti-aircraft guns seized from Jin Fatzi, and the anti-aircraft firepower along the entire line has been greatly improved, and now the air defense troops on the whole line are already in full array, waiting for Van Vliet's strangulation battle!
