Hogg and Schuchmann went to Nanjing with 30 helpers recruited from Shanghai and Lu Yuan's entrustment, because of Lu Yuan's reminder, the recent activities of the Shanghai underground party have become more secretive, and Lu Yuan, who has lost a lot of mundane things, has finally completely calmed down. Lu Yuan, who hadn't been in the basement for a long time, finally had time to re-take care of the small workshop he had built in the basement, and after getting a new batch of materials from Henry, Lu Yuan stayed in the basement all day, pondering how to improve the semi-automatic rifle that had been formed.

"Lao Xu, can you tell me that those rifles have been sent out of Shanghai by you? I'm in a hurry. "Several successive improvement failures have caused serious deformation of the barrels of the 38 rifles that Lu Yuan has in hand, so Lu Yuan can only hit Xu Huanshan with his idea." Okay, I'm not going to take advantage of you in vain, it's a big deal that I'll spend money to buy it from you, it's okay. Lao Xu, it's not that I'm talking about you, look at what your underground party has become, all of them are like money fans who have fallen into the eyes of money. ”

Lu Yuan didn't get a rifle from Xu Huanshan that didn't cost money, so after saying anything, Lu Yuan spent a lot of Guangyang to buy 5 brand-new 38 rifles from Xu Huanshan. "I said, what do you want so many 38 rifles for? Didn't you already take five last time? Xu Huanshan personally sent the gun to the door, which also somewhat wanted to find out Lu Yuan's true intentions, but I don't know if this is the meaning of the upper echelons of the underground party or Xu Huanshan's own meaning.

Although he was quite satisfied with the cooperation with the Shanghai underground party, it was impossible for Lu Yuan to open the basement to Xu Huanshan, so he only casually said a few perfunctory words, which made Xu Huanshan frown secretly. "Lao Xu, don't think about it, even if I told you, I'm afraid you won't understand. Anyway, you just need to remember that I, Lu Yuan, will never be an enemy of your CCP, and the reason why I returned to China is just to kill devils to serve the country, and as for other things, I am not interested at all. ”

Lu Yuanyun said a lot in the fog, and Xu Huanshan temporarily forgot to continue to ask, but he did not forget to lobby Lu Yuan to join the underground party, and Lu Yuan had no choice but to go to Xu Huanshan in a hurry to say goodbye in the name of going to the Rose Bar. Lu Yuan didn't know if Xu Huanshan would have a gap in his heart because of this, but he was not interested in politics from the bottom of his bones, all he wanted to do was to kill devils carefree, and he didn't want to be subject to any resistance and constraints.

Prevaricated and walked away Xu Huanshan, Lu Yuan immediately plunged into the basement and got busy, the time for the outbreak of the Battle of Songhu was getting closer and closer, and Lu Yuan's heart was getting hotter and hotter, and he was looking forward to what he could gain in this war. In accordance with his earlier improvement plan for the 38 rifle, Lu Yuan integrated the structure of semi-automatic weapons in Western countries, and combined with the characteristics of the American Thomson submachine gun that could fire single shots or burst fire, Lu Yuan made a large-scale adjustment to his improvement plan.

The barrel length of the Japanese-style 38 rifle was originally 797 mm, but in Lu Yuan's improvement plan, the rear end of the improved rifle barrel is threaded, which can be replaced and disassembled at any time. In this way, Lu Yuan only needs a gun body and a few improved barrels to ensure that this improved rifle has the practical effect of firing tens of thousands of bullets without interruption, and it will definitely not appear in fierce battles, because long-term shooting makes the barrel deformed by heat and reduces the shooting accuracy.

It's just that the current Lu Yuan is not only satisfied with this, after getting the 4x scope from the original German manufacturer from Hansen, Lu Yuan is thinking about how to add this 4x scope to the gun. The Germans used two types of frames for the 4x scope, a top-mounted frame fixed to the receiver ring and a side frame fixed to the left side of the receiver. The Germans placed the scope in this way, mainly because they did not want to affect the loading of the bridge, but Lu Yuan's improved rifle used a magazine to feed and loaded the magazine from the bottom of the magazine, which did not have the need to consider affecting the loading of bullets like the Mauser sniper rifle.

Lu Yuan finally decided to install the scope on the top of the rifle receiver in a proper manner, although the Zeiss 4x scope currently equipped by the German army is not as pleasing to the eye as the scope in later generations, but at present, it is already the most exquisite. After deciding on the installation position of the scope, Lu Yuan began to adjust the weight of the improved rifle again, although Lu Yuan had a storage space that could be called an anti-sky to store the rifle at any time, but Lu Yuan did not want to run and fight with a weapon that weighed as much as a light machine gun when fighting fiercely against the enemy.

The fit between the shooter and the butt of the weapon will affect the shooting accuracy to a large extent, which Lu Yuan saw from a military magazine, so he didn't want to make such a low-level mistake himself. However, how to adjust the butt was a big problem for Lu Yuan, he wanted to reduce the weight of the whole gun, but he did not have the plasticizing materials used on infantry weapons in later generations, so Lu Yuan could only find a way to find a way in the material and shape of the butt.

Because Lu Yuan's improved rifle shows the Japanese-style Tomosaka rifle cartridge, this Arisaka 6.5mm rifle cartridge is relatively small because of the small caliber of the bullet, and the recoil generated when firing is relatively small. Considering this, Lu Yuan decided to adjust the existing butt, Lu Yuan was originally going to adjust the shape and volume of the wooden butt, but later found that after adjusting the wooden butt, the improved rifle would jump up and the shooting accuracy would drop when firing.

As a last resort, Lu Yuan decided to use a steel folding butt, just like the steel butt of the German MP submachine gun. The seemingly simple folding steel rod butt is actually not bad at all, at least Lu Yuan didn't find any effect on himself when he used the folding butt to shoot. The problem of the mounting position of the scope and the butt of the gun has been solved, and the headaches of Lu Yuan seem to have been solved, but after installing the scope and folding the butt, new troubles have reappeared.

The receiver designed by Lu Yuan is slightly back, and after the scope is installed, the center of gravity of the whole rifle is significantly deviated backward, although this is convenient for the shooter to control the firearm, but in this way, the shooter will not be able to control the muzzle jump during the shooting. In order to solve this trouble, Lu Yuan thought about it and then came up with a stupid solution, since the overall center of gravity of the improved rifle was deviated backwards, then Lu Yuan installed a wooden grip under the barrel at the front of the receiver like a dog's tail.

After installing the front wooden grip, Lu Yuan suddenly felt that his improved rifle was much easier to use, especially when shooting, it was easier to control the gun body, and the added weight didn't seem to be nothing. Three days later, Lu Yuan pestered Xu Huanshan to get 5 38 rifles, and the 5 rifles he got this time were not wasted by Lu Yuan in continuing the test, but directly removed the barrel as a spare part.

Lu Yuan not only pulled out the threads at the rear end of these spare barrels, but also pulled out the front threads at the front of the barrel that could be used to install silencers, for which Lu Yuan also made several rifle silencers. The installation of a silencer, to a certain extent, will make the center of gravity of the rifle move forward, and it will inevitably affect the accuracy of the shooter, but the solution that Lu Yuan thought of is extremely simple, just add a steel fixed weight clip behind the scope base above the receiver after installing the silencer.

The modified rifle after Lu Yuan's several improvements and field tests looks very strange, and the improved rifle with no paint at all looks like it was picked up from a trash can, but Lu Yuan likes it very much. "There's no way, the materials and equipment are not up to par, if you give me good enough materials and equipment, I can build an eight-one bar or AK." Looking at the strange-looking modified rifle on the workbench, Lu Yuan was happy but also had a faint sadness.

"It seems inevitable that a trip to Germany will be made." Tidying up the excess materials in the basement, Lu Yuan lit a cigarette and smoked it slowly. He originally promised General Haussmann that he would go to Germany in February next year, but in fact it was just Lu Yuan's delaying tactic, in order to gain the support of the Germans during this period, and to protect the civilians of Nanjing with the help of the Germans after the Japanese army broke through Nanjing. But now it seems that it is necessary for Lu Yuan to really go to Germany once, because he needs better materials and equipment to prepare better weapons and equipment for himself.

Although Germany's industrial capacity and foundation are not as strong as those of the United States, the technical level and rigorous attitude of the Germans in industrial manufacturing have been continuously praised by later generations. If Lu Yuan wants to obtain a high-precision combat weapon, going to Germany may be the best choice, after all, there are too many weapons manufacturers in Germany, and the quality and reputation of German-style weapons are obvious to all in the world.

After adjusting his modified rifle and waiting for the outbreak of war, Lu Yuan did not waste this time, in addition to his daily unremitting physical exercise and tactical training, he was nesting in the study to draw weapon drawings, and the entire study was already full of weapon drawings drawn by him. Although the AK rifle is more powerful than the Bayi-bar rifle, Lu Yuan believes that what he needs at this stage is a semi-automatic rifle that can be easily replenished with ammunition in enemy-occupied areas, and the 6.5mm Yusaka rifle cartridge cannot give full play to the true power of the AK rifle.

In Lu Yuan's busyness, time passed little by little, and after entering the second week of August, there were suddenly many more soldiers of the national army in Shanghai. The information transmitted from Xu Huanshan showed that the merchant group escorts in the Japanese concession had already distributed weapons and ammunition, and the Japanese expatriates scattered in other concessions were gathering in the Japanese concession.
