After Cao Qing left, there was a sound of a neck bell, and it was the donkey Xiaobao who came.

"Omwoo!"

It says that these two notes are here to report the work of the spy. Each report can be exchanged for a glass of wine. Wine is a real luxury in Funing County.

Khan, it would be great if Anton had it simple. Everything that donkeys said was two words, and everything that Anton said was a long story.

After listening to Xiaobao's report, he found that Cao Qing's actions in the machinery factory were logical, so Dalian felt even more relieved. He confirmed that Cao Qing was a good lady and could just lead this nun into the Demon Sect.

Then, he also confirmed from Xiaobao that no one in the machinery factory was lazy.

"Omwoo woo woo woo!"

Donkey Xiaobao didn’t see wine coming out, so this time it means “Wine is wine, wine is wine, wine is wine.”

Wang Yun came out of the bunker and hid the wine under the bed. He poured it a glass of wine, fed it, and scratched the donkey's head: "Come on, I'll take care of you."

"Omwoo." Donkey Xiaobao said he wanted another drink.

As a result, he was slapped in his head and Wang Rong said, "Get out quickly, I want five thousand strategic bombers, if you want it, you have it."

Donkey Xiaobao left. The biggest benefit of this donkey is that it is very gentle and easy-going. Erya spit out the things it ate, but it was not angry...

As Cao Qing said, under the leadership of Daxiang Stalin and Hitler, the steam engine has made gratifying progress, and the entire technical team is like a chicken blood, and the public relations are constantly being repeated day and night. Now many core components have been manufactured.

But it still did not combine it into trial run according to Wang Rong's requirements, and the bottleneck lies in the welding process.

In the relatively high-precision unit, it is impossible to connect by riveting, but Lao Luo used the method of melting iron powder to connect. However, the effect is not good, and there is no need to install the ignition, but it can be disconnected by ordinary tensile resistance and other tests. Therefore, this is still an immature method and cannot be tested, otherwise it will definitely destroy other inappropriate core components.

For example, the cylinder is made of sand, cast, and polished. Finally, Lao Luo’s father brought three top-notch technicians to correct it one by one. This project is very huge. If the unit is disconnected and disintegrated after operation, the iron slag fragments can easily damage the hard-earned cylinder.

These are all difficulties faced, and the relevant teams need to keep trying and making mistakes and finally solve them. Wang Rong knew that they would not be able to get it, so he did not urge him.

What made Dalian happy this time is that Songgang No. 4 has matured.

This makes it possible to process the barrel.

It is not that Songgang No. 4 is used as barrel material, but that it is already available to ensure that the chamber does not explode. It is Songgang No. 2 earlier.

Songgang No. 4 is a high-quality product, but it is only produced in a high-difficulty and small batch. Its biggest advantage is that it solves the tool needed to manufacture the gun barrel - a high-hardness drill bit.

The quality of the Tiandao-grade material forged by Lao Luo’s father is far inferior to that of the Tiandao-grade material, but coincidentally, after testing according to Wang Rong’s requirements, the drill bit made of Songgang No. 4 with abrasive tools can basically achieve the lower limit of geometric accuracy requirements, and it can just chew the standard iron rod cast by Songgang No. 2, and the wear is within an acceptable range.

It is enough to use it, so drill bits that cannot be hand-forged can now be tested. This is because the drill bits that make barrels have too high requirements for the integrity of geometric forms. Manual forging can solve the accuracy but cannot guarantee the integrity of geometric forms. Therefore, when there is no related machine tool, this thing can only be cast with abrasives. After forming, it is polished and made subtle corrections by hand.

This is a milestone.

Songgang No. 4 can make bad drill bits, which means that when you make adjustments, there will be many derivatives, including gears, bearings and other things that cannot be forged.

Of course there are problems, and their lifespan will not last long. But as long as you can, you can solve the problem of existence or not, and try and make mistakes slowly. As long as you have money, it will definitely get better and better.

In the past, the barrel was not impossible to build, but it could only be a real top technician. He repeatedly beat and corrected it, and finally bonded with a clumsy "welding" method like a roll of paper and cigarettes. Therefore, although it was a high-quality forging, the welding ministries and commissions were short-lived and there was a risk of explosion.

On the contrary, the low accuracy is not a disadvantage. Anyway, it is the guns of the American imperialists in later generations. Afghanistan and Iraq only eliminated an opponent after thousands of bullets. In this data, the accuracy is a hooligan. No matter how poor the accuracy is, it cannot escape the ones that should be hit, for example, it can hit any distance of three or five meters.

From this concept, a gun is just a meaning and a symbol. It is also a link of industrial accumulation. Through it, many meaningful things can be derived. It is really not that a flintlock rifle is a magical tool.

In terms of power, the flintlock rifle is really one level worse than the current version of the Divine Arm Crossbow. When talking about the rate of fire, it is indeed difficult to launch an arrow from the Divine Arm Crossbow, but it is not slower than the guns that can be made now.

It is even more nonsense to talk about shooting accuracy. Unless it is a street combat sniper war, the role of long-range weapons must be focused on quantity, that is, cluster coverage, so there is no need to be precise, but the well-trained crossbow and arrow troops will conduct centralized coverage to a certain area in a unified pace.

In these senses, in addition to being much more powerful than the flintlock rifle, the Divine Arm Crossbow can allow it to attack further parabolic, but the flintlock rifle cannot.

However, a gun has a characteristic: it is cheap.

Things under the sun are the problem of money being impossible to avoid. The cost of a lead bullet will be only one percent of the qualified arrow. Then, according to the Song Dynasty's craft god arm crossbow, it cannot be mass-produced. Only the top masters of Lu Ban can make it, and it will take as soon as two years to complete the process.

There were millions of imperial guards in the Song Dynasty, but there were less than 10,000 divine arm crossbows. This data is the equipment stock that has only been accumulated over the years.

Say it back.

Before Song Gang No. 4 broke through, even if he had a brainwalk, the manufacturing of qualified gun barrels required technicians to slowly tinker with them in March. But now, according to Wang Rong's plan, apprentices who have been simply trained can use two fixed vises on the workbench to fix the iron rod, and then follow the fixed track, shake the connecting rod with their arms, and slowly chew the drill bit made of Song Gang No. 4 like a screw chewing wood.

This is a magical process, and Wang Rong's imagination has once again become a miracle by everyone.

For the time being, no one knows that these processes are used to make the barrel of flintlock rifle, but this technology can be used in too many fields and too many things that can be derived.

Seeing that it took several months before, the master-level people took action to create such a tube, now any preliminary training apprentice can get three tubes in one day. It’s amazing.

At Wang Rong's level, this will be a future revolution in military equipment. The Divine Arm Crossbow will still have it, but it is high-end military equipment, and is exclusive to special tactical forces. However, the basic combat structure of ordinary big-headed soldiers will have subversive changes and will be very cheap.

Of course, as a vulgar arms dealer, Dalian still has a long way to go to how he finally communicated with bureaucrats including his father and how to promote this change. These are politics, reforms, and interactions between capital. It is not a simple battle between two armies, which would seem very complicated.

The concept of law is simple. Wang Rong cannot build arms because he does not have this license qualification. Especially in terms of divine arm crossbows, with Lao Luo's father joining and strong team cooperation, Wang Rong can really build divine arm crossbows. The quality may be worse than that of military military supervisors, but it will definitely be useful and will be cheaper.

Unfortunately, the Song Dynasty's control of crossbow arrows and armor was even more severe than the later Turkish Communist Party's attitude towards gun control, especially the Divine Arm crossbows that can only be manufactured by military supervision and are strategically controlled measures.

However, guns are not considered weapons for the time being in the Song Dynasty. So let’s not talk about the plan to sell guns to the Privy Council. Even as technical verification and accumulation, Dalian plans to build a batch of reserves in the hands of the reserve militia when the finances are more relaxed, and even the whole people will be soldiers. This is the war potential reserve in Funing County.

After the first batch of earth guns were built, it was completely certain that they were not as powerful as the Divine Arm Crossbow. Even ordinary archers who had not been trained were powerful, but the biggest advantage was that they were simple to manufacture, low cost, and relatively simple to train, and the entry threshold was very low.

Generally, people over twelve years old and have no disability and IQ defects can become useful musketeers in just one week. There is no need to talk about accuracy and accuracy, which is a hooligan. In short, unless professional snipers fight special tactics, even if the US military does not lack bullet practice, it will be like that. If you sway three or four meters ahead of him, you will be killed by a shot. In fact, women in Funing County can also do this with flintlock guns.

As for further places or large-scale position wars, it depends on continuous firepower clusters for big data coverage, which is commonly known as "Du Meng".

The foreseeable potential of gunmaking can be very vulgar. In the future, the real mechanical power will be even more vulgar...
