Anti-Japanese War, weapons designer at Fengtian Arsenal

First of all, there is the semi-automatic rifle. Li Qinwu has an important specification for the semi-automatic rifle, which is that it must fire the Japanese 6.5x50mm Arisaka rifle bullet. This is the most easily obtainable ammunition for him now, and this must not be changed.

After deciding on the ammunition, the next step is the semi-automatic launcher of the ammunition. Which one should I choose?

Four semi-automatic rifles popped into his mind, namely SKS, SVT-4, G40 and M43 Garand.

He wrote the names of these semi-automatic rifles and their semi-automatic principles on the drawings, and then he used the process of elimination.

First of all, SKS is ruled out. This semi-automatic rifle fires intermediate-power rifle bullets, and this gun uses a bolt offset locking. This locking structure has the advantages of strong rigidity and reliable locking. However, the bolt wears a lot during the unlocking and locking process, and the life of the bolt will be very short.

This problem is not a big problem for a semi-automatic rifle, and the performance of steel in later generations is very good, so this wear and tear can be almost ignored.

But Li Qinwu is now living in the Republic of China, and the quality of steel produced is not good. The wear and tear of the bolt is very serious. The gun may be scrapped due to wear and tear after firing 1000 rounds. Therefore, the world-famous SKS gun cannot be produced at all.

The Soviet SVT-40 and the German G43 have the same problem. These two guns are complicated! Very complicated!

The Soviet and German armies reacted when using these two guns, finding them either too bulky or with too complex parts, making them difficult to maintain, expensive, and requiring high production demand.

The rifles produced by Li Qinwu are for his brothers to use. He cannot blame them or the production line, so these two guns have to be ruled out.

Finally, Li Qinwu's eyes stopped on the M1 Garand.

Compared with the above semi-automatic rifles, the advantages of the M1 Garand are irresistible to Li Qinwu. It is reliable, effective, and the most powerful combat rifle in World War II!

However, its shortcomings also gave Li Qinwu a headache. It could only hold eight rounds of ammunition at a time, could not be replaced midway, it bit his fingers when he shot, was heavy and bulky, and expensive, much more expensive than other rifles.

These shortcomings must be improved, otherwise the combat capability of the Punishment Army will not be greatly improved.

Li Qinwu started the long drawing work again. He first drew the original M1 Garand drawing, and then focused on the modification of the ammunition supply system.

The main modification direction is to change the Garand's magazine feed to a box feed, and see if a 25-round magazine can be inserted.

While drawing, Li Qinwu suddenly remembered something. It seemed that the M14 automatic rifle was made based on the Garand, with a speed selector and a 25-round magazine.

The M14 automatic rifle inherited the main structure of the Garand and added a fully automatic firing mode. However, the structure of the Garand was not simple to begin with, and the M14 became even more complicated with the automatic firing mode, and it did not withstand the test of Vietnam's humid climate.

Soldiers reported that the M14 had very poor reliability, was heavier than the Garand, and was almost impossible to control in full-automatic mode. It was a failed rifle, and the U.S. military subsequently introduced the M16 to replace it.

Although the M14 was a bit of a failure, its ammunition supply structure was successful. Li Qinwu directly moved the M14 ammunition supply structure to the Garand.

After several days of drawing, Li Qinwu felt dizzy and his head was swollen. Except for eating, defecating and sleeping, he didn't even move his butt.

Fortunately, the results were remarkable. A Garand rifle with a magazine inserted appeared on the paper. This gun uses a 25-round magazine, which greatly improves the sustainability of firepower. Soldiers no longer have to worry about the receiver biting their fingers, there is no missing clip, and there is no ding charge reminder sound.

In addition to the above improvements, he spent a lot of effort to reduce the weight of the gun. The buttstock and handguard use many hollow ceramic steel parts, plus a ceramic steel barrel. The reputation of Garand being bulky should be removed.

Li Qinwu also added a muzzle brake to the muzzle to increase the soldier's control when firing continuously.

After the drawings were completed, they were sent to the Taogang Factory in Hutoushan, asking them to make 100 units first to see if they would work. After all, this was a combination of the M1 Garand and the M14, especially since the ammunition supply structure had been modified a lot, so it was very likely that the shortcomings of both armies would be combined, so it had to be carefully tested before it could be put into service.

After dealing with the two guns, Li Qinwu felt quite tired. He put down his pen and planned to go out for a walk.

Pushing open the door of the house, there is a construction site outside. Hundreds of heavy machinery are moving back and forth between the portals. They are pulling various gravel materials into the sea, expanding the land area of ​​the island space.

At the same time, factories and high-rise buildings sprang up, each of which was more than 10 stories high, which were skyscrapers that people of that era could not imagine.

All these buildings were built under the supervision of Li Hanchao. He worked as a contractor for the Japanese and had a very good relationship with a Japanese architect. The origin of that Japanese architect was also shocking. Before coming to the Northeast, he was a designer who was highly involved in the construction of Gunkanjima!

Gunkanjima is a small island next to the Japanese Nagasaki Prefecture. There is a lot of coal on it. In order to open mines there and expand the area of ​​the island, the Japanese made it look like a warship, hence the name.

In order to cram enough coal miners into such a small area as Gunkanjima, the Japanese built many high-rise concrete buildings on it.

The average height of buildings in this era was two or three stories, and those with four or five stories could be called high-rise buildings. However, on Gunkanjima, buildings with more than ten stories were common.

It can be said that the buildings on Gunkanjima represent the highest level of Japanese architectural technology, and one can imagine the level of architects who came out of them.

This senior Japanese architectural talent has a very good relationship with Li Hanchao. Li Hanchao has absorbed a lot of great construction experience from him. Now, all this experience is used in the construction of island space. Currently, there is no island space with less than 10 floors.

Li Hanchao is very ambitious. He wants to build taller and bigger buildings. Currently, the tallest and largest building on the island is 20 stories high. It is 80% completed and is in the process of being topped out. Once this building is completed, Li Hanchao will aim to build a 30-story building!

Li Qinwu glanced at the dusty construction site, retracted his gaze, and started walking around in the island space.

Now, because there are more than 100 construction vehicles, the land reclamation plan of the island space is very fast. Two quarries in Henan have been dug out. Now the area of ​​the island space is about 400 meters long and wide. Li Qinwu plans to move some important pollution-free facilities here.

He walked to the beach by the sea, where rows of coconut trees were transplanted. Under the coconut trees, a bamboo pavilion was built. Various drinks, foods and lounge chairs were placed inside the pavilion. This was a place for the clones to rest.

At this time, Li Jianfeng and several special forces members were sitting on recliners in their shorts and chatting. Li Qinwu went over and lay down next to them, looking at the sea in the distance to calm his mind.

"We need to put the exploration of the island space on the agenda. We don't know how big this place is, and whether there are other islands. We just happened to have robbed a transport ship and a destroyer, so we can send them to explore around."

Li Qinwu muttered to himself, and suddenly, his sight was blocked by Li Jianfeng and the special forces members. The special forces members surrounded Li Qinwu and looked at him with expectant eyes.

Li Qinwu was stunned.

"what?"

Li Jianfeng asked seriously: "Master, have you forgotten something?"

Li Qinwu scratched his head.

"What? What did I forget?"

Li Jianfeng held his forehead.

"Sign in! The month is almost halfway over, where's your sign in?"
