Xishan Island, the center of Zhongdao.

Chenjiawu, surrounded by mountains, built a high cement wall. The trenches outside the wall are deep and thorns are covered with thorns. Every mile away, there is a lookout for the building. Security guards are guarding the building day and night.

This extremely hidden secret base is the Ordnance Research Institute affiliated to the Military Weapons Bureau of the Nanjing Ministry of Works.

However, the heads and minds of the Ministry of Works and the Military Weapons Bureau do not even know that this research institute is on Xishan Island.

Zhao Hao only held the title of director in Jiangnan Company, but personally served as the director of the Ordnance Research Institute, which shows his importance.

Moreover, this research institute does not belong to Jiangnan Company, but is controlled by Singularity Investment, who is solely owned by Zhao Hao.

Because Hua Bozhen, Jin Ke and others regarded it as the top secret of the young master, no one was allowed to get close to Chen Jiawu.

There are three guard posts at the only entrance and exit of the institute, and all the people entering and leaving have to go through layers of inspection. It is not because Mr. Zhao came to inspect today that he pretended to behave.

After entering, you can see that the site of the institute is rectangular. There is a neat row of clear water concrete buildings at the east end, and a small blast furnace chimney is emitting smoke.

That is the materials laboratory, forging workshop, and assembly workshop of the institute.

Because this is just a place to test the firearms, it is not large in scale and not many people.

But the so-called sparrow is small and has all the internal organs. Although these rooms and dozens of people can complete the entire process of producing muskets. It can be said to be a small arsenal that is fake.

Today, everyone in the institute put down their work and excitedly came to the shooting range in the west to watch the acceptance test gun.

They created the first flintlock rifle of the Ming Dynasty by themselves.

On a long table covered with blue tablecloth, three types of firearms were placed, five in each.

One is the bird-beak gun sold from Guangdong, which is also the best quality combing gun in the Ming Dynasty.

One is the Spanish flintlock rifle purchased by Mr. Zhao from the Flangji people in Macau at an extremely high price.

Finally, there is the five-pole Longqing-style flintlock rifle that was imitated by the institute without white or black.

From the appearance alone, the Longqing style is better than the Guangdong-made and slightly inferior to the Spanish rifle.

This is the gap in craftsmanship, but there is no big problem. In this era, don’t laugh at the second brother, no one is much better than anyone else.

Zhao Shizhen, the chief researcher of the Firearms Research Institute, rubbed a flintlock rifle affectionately and explained to Mr. Zhao:

"Although my girl is not as good as that Tycy's girl, she has the advantage of being simple in the gun, which has reduced 20% of the parts, and has a higher firing success rate."

Mr. Zhao couldn't help but shivered, and hid behind the cover with Zhao Liben, who was visiting with him, and said, "Fire a few shots and see if you are bragging."

Several gunmen stepped forward, picked up the Guangzhou-made convex gun and started loading.

They first poured the induction medicine into the induction medicine pot, closed the lid of the induction medicine pot. Then they put the gunpowder in turn, compacted it through the strips, filled it with the projectile, and compacted it again.

Finally, the fuse was lit and the fuse was fixed to the fuse clamp, and the firing preparations were finally completed.

Several other firearmers also picked up the Longqing flintlock rifle and started loading.

In fact, the steps are quite different, but the steps of lighting the fuse and fixing the fuse are missing, so the time it can be saved is not obvious.

Zhao Shizhen told Zhao Hao that after repeated calculations, each shot saved about one-fifth of the time.

Moreover, when the convex gun is fired, the explosive gas will flush the convex away and must be reignited and clamped.

So each shot can save one fifth of the time, and the sum is still considerable.

The real advantage of the flintlock rifle is actually in its firing efficiency. Only when the flintlock rifle is pulled twice can it be successfully fired, but it is almost impossible to fire the flintlock rifle.

Moreover, after the flint gun is silent, it is necessary to re-fire the flintlock gun. However, the flintlock gun can be re-fired by just pulling the hammer.

It saves more time here and there.

When all five Longqing-style five rounds were fired, Guangdong made four shots, and the fewest shots were fired...

The gap is still very obvious.

Then, the gunman tested the Spanish rifle and the Longqing style at the same time. The design speeds of the two were comparable, but the Longqing style had a slightly lower range, but it was not bad.

This marked that the Ming Dynasty's musket technology had caught up with the European power.

Mr. Zhao expressed his satisfaction and praised the personnel involved in the research and development on the spot, and enthusiastically encouraged them.

"Young master, the old man dares to guarantee that the bird gun will be eliminated immediately after taking out this Longqing style." When everyone below retreated, the old man Gao, the executive of the institute, sighed with emotion: "I didn't expect that the musket could be fired like this."

"I will not use this semi-finished product to embarrass people." Zhao Hao changed his face and shook his head flatly: "With this slow firing rate and no progressive range, how can he be a cavalry? How can he fight the Tartars for General Qi?"

With Mr. Zhao's picky eyes, how could he be satisfied with a musket that had been created by the Thais for more than ten years?

Zhao Shizhen's face turned red when he heard this, as if his daughter was insulted. That's when he said this, his uncle, otherwise he would have to get angry.

"Uncle gives me some more time, and I will definitely increase my firing rate!"

"What do you think?" Zhao Hao asked.

"My nephew is thinking about a musket that can hold a sub-gun afterwards," Zhao Shizhen became excited again and said, "We pre-install gunpowder and lead pills in the sub-gun. In this way, as long as the medicine twist is inserted into the buttocks of the sub-gun, the medicine pool can be removed."

"This method should be fine when used on a coercine, but if you change it to a Longqing style, you have to think about how to fire it." Zhao Shizhen said regretfully.

Zhao Hao blinked and looked at his nephew for a while, patted his shoulder hard and said, "You are so fucking genius!"

This is the original fixed-loading bullet.

"Ah, uncle, is my nephew's idea right?" Zhao Shizhen was surprised. His ideas were wild, but without his uncle's far-sighted scientific guidance, he would inevitably take countless detours.

"Yes, right, it's just that the steps are too big and it will cause a lot of money." Zhao Hao smiled and said, "You are loading a rifle in the back, and the airtightness is far worse than the current front-loading gun. With the current level of black gunpowder, the range cannot be seen at all."

"Ah..." Zhao Shizhen couldn't help but feel angry.

"So, no matter how advanced the concept is, it needs to be practical." Zhao Hao gained great happiness by teaching the palace-level gun masters.

Seeing that Zhao Shizhen was a little weakened by the blow, he smiled and said, "But you can do a paper-shell fixed-loading bullet first. This is easy to build. You don't need to teach you how to do it, and it can increase the rate of fire by a large margin."

"Get another bayonet out, let's set the Longqing style first." Zhao Hao raised his hand and passed the design acceptance.

"Young Master said that you can't take this gun?" The blacksmith couldn't help but say strangely.

"I mean you can focus on formulating standardized production standards and improving the quality of the barrel and the power of gunpowder." Zhao Hao said, and said to Zhang Zai on the side: "Help Shizhen and try to build the manual boring machine as soon as possible..."

Before he finished speaking, he saw Xiwa running in with a panic on his face.
