Bai Shujie used one day to investigate several key points non-stop.

At the Gangnam airfield in Pyongyang, only one squadron of Flying Tiger fighters and one squadron of light bombardment remains. Bai Shujie ordered the on-site construction personnel to continue digging the cave, and all the oil storage tanks were 20 meters deep into the cave, and four tank trucks had to dig the cave separately. Of course, these caves have exhaust holes.

At the Miaoxiangshan Plateau Basin Airport, according to Bai Shujie's order, the fighter flying dragon squadron, the heavy bombardment squadron, the cadet brigade, the baggage squadron, and the aircraft maintenance workshop are all here.

At present, the site leveling has been completed, and we are working overtime day and night, and we must pave the concrete on the runway before freezing.

This time, four runways were built at the same time, with the main runway for heavy bombers being 1,500 meters long and the fighter runway being 1,000 meters. A light railway is also under construction, which will be a supply line in the future.

The communication command tower hidden in the dense forest of the main peak of Myoxiang Mountain has been installed, after all, it is all a ready-made thing to rob, as long as it is assembled.

However, the iron frame of this tower, which was originally 68 meters high, is now placed on the main peak of Miaoxiang Mountain, which is even more "stand high and hear far!" ”

The little devil turned out to be a communication tower in Tongguò, which was originally used as a relay station, which was able to directly connect with Monkey Island from Jinzhou, with a radio wave coverage radius of more than 2,000 kilometers.

Now that Bai Shujie can be used to detect dangers in the ocean, an air defense warning system is being installed. With this communication tower, the intelligence department's work capacity has been greatly improved, and the coverage radius of the monitoring radio exceeds 2,000 kilometers.

Of course, all three high-power radios were snatched up along with the communication towers. It turned out that there was a 150W high-power radio station in Chengde, and General Political Commissar Yang Chengwu said that he would not take anything away. Only then did Bai Shujie make up his mind to snatch back the little devil's communication relay station at any cost.

The progress of the dock in Hequanli, Bai Shujie is not very worried. By the time the little devil figured out where his few warships had gone, the dockyard here would be pretty much the same. The warships of the little devils did not dare to come in, that was for sure. If the warship is shelled from the sea, the accuracy may be difficult to say.

The little devil originally had a cement factory (ash factory) in Pyongyang, and from Jinzhou he dismantled part of the equipment of the local cement factory, and now the automation process is much higher, and the output has increased rapidly. After all, Bai Shujie is not a little devil and cannot abuse workers.

With the guaranteed supply of cement and the fact that it is the season to sell water, the construction of the dock is not very difficult. The only requirement put forward by Bai Shujie is that the dock should ensure that the working surface of the keel length reaches 420 meters × 90 meters.

Three wharves were built to accommodate three 5,000-ton freighters. The gantry crane designed by Bai Shujie, with a maximum lifting weight of 30 tons, is also currently under construction in the steel mill.

The cleaning of the river silt was also carried out simultaneously, and Bai Shujie asked for a water depth of 4 meters. The dredging boat is still left by the little devils, and now it barely meets the requirements.

Seeing that what he should be pointing out had already finished "pointing and pointing", Bai Shujie rushed into the construction site of the Black Ridge Arsenal for three days and did not come out. This is an abandoned mine converted into a temporary use, and a real arsenal is digging a cave.

It turned out that when Bai Shujie was in Chengde, he hid in a dark corner with a group of young people. These 37 young people have all studied in college, and it doesn't matter if they graduate or not, they can be regarded as "top talents" in this era anyway.

Although Bai Shujie did not go to college, the things in his head are much richer than those of college students in this era. Therefore, Bai Shujie is now the "professional mentor" of these "top talents"!

What to study?

The first item is gunpowder, and the key is the propellant. The firearms used by the Wyvern Expeditionary Force now, both in terms of range and accuracy, are second to none in this era. If the gunpowder level can't keep up, the replacement of weapons will have problems.

The second research topic is various armor-piercing shells. Rifles, machine gun bullets, and all kinds of artillery require trial and error.

The third and most important research topic is the new weapon research topic that Bai Shujie is directing: the "copycat" Russian Van Pier RPG-29 105.2mm rocket launcher!

According to the technical parameters set by Bai Shujie, armor-piercing shells equipped with tandem warheads should be fired to destroy tanks, infantry fighting vehicles, armored personnel carriers, self-propelled guns and other armored vehicles. The firing range of the ruler is 480 meters, the thickness of armor piercing is 650mm, and the weight of the bullet is 10-12kg.

When I was in Chengde, two bodies had been trial-produced, but there were two biggest problems: the armor-piercing bullet was not up to par, and the armor-piercing thickness could only reach 180mm; To make matters worse, the set ruler had a firing range of 480 meters, and as a result it was only possible to reach 210 meters.

In other words, the current situation is similar to that of their own recoilless guns, and this blow is too close for the fighters and is very unsafe.

The fourth item is that Bai Shujie hopes to be able to "copy" an anti-infantry mine. After all, he has no strategic depth to maneuver now, and there is a problem with the replenishment of troops, and the long defensive front is really a little too much to take care of.

The so-called anti-infantry landmine is a weapon that kills innocents indiscriminately, whether it is a friend or foe, a soldier or a civilian, as long as it is triggered, it will be harmed.

The main uses are: (1) to cause casualties; (2) prevent enemy soldiers from clearing anti-tank mines; (3) refusal to visit the Wèn territory; (4) to provide security around the perimeter of the troops' line of defense; (5) Emergency alarm.

Advantages: low manufacturing cost, can be used in all weather and all regions, simple layout, only requires little training to use; Lightweight and small, it doesn't pose an overwhelming logistical burden.

Disadvantages: Bombs regardless of target triggering, hinders the mobility of friendly infantry, and cannot be reused; In addition, conventional landmines have long-term lethal capabilities, and their location and records throughout the battlefield are inaccurate, which can continue to pose a potential danger after the conflict has ended.

As for the danger of anti-infantry mines, Bai Shujie knows it well. So he was not ready to produce too much, the first batch of 10,000 pieces. In addition to 1,000 per field division, they were mainly deployed around airfields.

There is also a small part to be given to the special combat team. If you have the opportunity, you can do some "Red Terror" and get two for the little devil's barracks and near the headquarters to taste it. As long as you can make the enemy scared, you will usually be able to sleep well.

Bai Shujie will never forget that when his brother attacked the airport, he was killed by a little devil's mine.

This revenge is not a gentleman. Don't look at him this time he didn't shed tears, but deep down in his heart he never forgot the painful lesson of jì, as well as those brothers who will never come back!

The object of Bai Shujie's "copycat" is the Type 58 anti-infantry mine in later generations, that is, the Soviet-made PMN mine. The mine is a pressure-blasting anti-infantry mine, which mainly kills the enemy's living targets with the high-temperature and high-pressure gas generated after the charge explodes.

This mine has a number of advantages.

First of all, with the exception of the firing device and the initiator, most of the parts, such as the mine shell, are injection molded from plastic, which is inexpensive and easy to manufacture. At the same time, due to the large number of plastic elements used, the probability of being detected by enemy mine detectors is also greatly reduced.

Secondly, the structure is simple, and the killing effect is not bad. It has the appearance of a cylinder, with a total weight of about 600 grams and 200 grams of explosives inside. Due to the large amount of charge, it also has the function of destroying the tires of the enemy's wheeled transport vehicles. Plus light weight, easy to carry.

Now the field division has an engineer battalion, but after the completion of the fortifications at present, there is no room for large-scale maneuver for a long time, so these sappers should do something else.

Bai Shujie's point of view is that sappers are also combat soldiers. While clearing enemy mines, it is necessary to immediately plant thorns in the enemy. One sapper carries four mines, which is not at all in the way, relieving the logistical pressure.

What needs to be further improved now is the issue of the final finalization of the pressure detonator and the detonator shell. Bai Shujie felt that it was too cruel to blow people up directly, and he should create a large number of disabled people for the little devils.

So it is ready to reduce the weight of the mine to about 400 grams, that is, eight taels. Inside the plastic shell, it is filled with irregularly granular selected sea sand. To put it bluntly, it's coarse-grained quartz. This thing is not metal, it is resistant to high temperatures, and metal mine detectors cannot detect it.

As long as a mine explodes and thousands of quartz sand fly up, people within 20 meters of the vicinity will basically become blind, or at least pockmarks!

Even if the little devil is not roasted to death in the high temperature, he will become a wounded person covered in bruises, looking bloody, but there is no way to bandage it, this is the effect that Bai Shujie likes.

There is not much on the Korean Peninsula, but the sea sand is inexhaustible. Now he is taking his "graduate students" to repeatedly test what kind of sea sand can withstand the instantaneous high temperature caused by the explosion of the mine.

In fact, Bai Shujie also figured out later, when the quartz melts, it is glass, and it is more difficult to blow it into the muscles. So today it was decided to finalize the mine and put it into mass production immediately.

Just when Bai Shujie felt a sense of accomplishment, Huang Qiaoyun, the head of the guard regiment, ran in and said, "Report: Sister Jin Xi asked you to go back immediately, saying that there were guests, and they didn't know how to receive them!" ”

"What's going on?" Bai Shujie was a little inexplicable: "There is Zhang Yushu in Pyongyang, and there are Zhao Jinxi, Gan Tong, Lu Ming and others in the headquarters, what kind of guests still need Lao Tzu to come out in person?" ”

"Why don't you go back, Rory?" Huang Qiaoyun has never given his senior brother any face: "It's three days when you come out, don't you know that the recent form is very strict?" ”

"Know, know, let's go!"

Bai Shujie understands that with his little junior sister, he must not want to make any sense. Because the truth is in her little mouth, faster than the rate of fire of the Sumi 1931 submachine gun, you don't want to say win.

"What's going on?"

Back at the headquarters, it was already two o'clock in the morning, and Zhao Jinxi, Gan Tong, Lu Ming, Qin Yuefang, and Yang Erya were all there. Especially seeing that Qin Yuefang and Yang Erya, the two female generals, were also waiting here, Bai Shujie felt that things must be a big deal.

Qin Yuefang, who is called the Minister of Political Affairs to the outside world, should actually be called the "Minister of Political Examination", who specializes in secretly examining certain special personnel.

Not to mention Yang Erya, he is now the head of the Security Department of the Headquarters, that is, a figure who is similar to Dai Li, who is next to Jiang.

Yang Erya has her own privileges and has always implemented the "inference of guilt".

No matter who is in her eyes, there is a problem first, and the key is the difference in the size of the problem. Unless she doesn't catch your pigtails, you'll just wait and see!

If you are invited by Yang Erya to drink tea, you only have one thing to do: hurry up and come up with evidence to prove your innocence. Don't say anything else, or it's all over.

After all, what happens next, let's see how it will be broken down next time.
