How to solve the problem of transportation and storage of picric acid explosives? This matter is difficult for others, and it is definitely not difficult for Zhu Youxiao.

Because this incident has been a secret disclosed in later generations. Of course, in the Ming Dynasty, no one could know about it.

It is actually very simple to tell this secret. In fact, many techniques that have not been figured out are sometimes very simple.

Many examples tell everyone that it is such a simple secret that sometimes it will cause a war, or even a war that lasts for many years.

The secret is to paint the inside of the shell and attach a thick layer of paraffin to isolate the direct contact between the picric acid and the shell of the shell, and solve the big problem with such a simple, clever and cheap method.

Although paraffin will fall off over time, causing the picric acid explosive to be unable to be stored for a long time, at least it can be guaranteed to be used.

Moreover, as a large number of consumables, can the shells be stored on the day the paraffin falls off?

For Japan at that time, their national strength was poor and their output was very small, so they had to think about it in many ways.

This ingenious gene also continued to the later design of the Type 38 rifle, and a dust-proof cover solved the problem of the rifle's isolation from sand and dust.

Now Zhu Youxiao takes it over and uses it, which is just right for the current productivity.

The production of picric acid is simple and low, and it is also powerful. If it solves the problems of transportation and storage, then there will naturally be no other problems. This is a very good gunpowder, which is just used as a metal-mounted shell.

This kind of gunpowder invented by the French ended up showing off his skills in Japan. In fact, the French also knew that this thing was very important, so they only wanted to sell it to the Japanese finished products, not to let Japan study it on its own, and even less to give it to Japan production lines.

But the Japanese did not give it to you for nothing. When visiting the French factory, there was a man named Tomooka Tatsuki.

Tomooka Takiko was a humble and studious figure. He carefully pinched a pinch of bitter acid crystal particles, rubbed them, looked carefully with his eyes, put them on his nose, and smelled them with his hands, and felt the feel of them. He almost put them in his mouth and tasted them, and then put them back as if nothing had happened.

Back at the Japanese delegation's headquarters, Tomooka Taki Kyo carefully picked out a small piece of picric acid powder from his fingernails. After several twists and turns, these precious powders were finally handed over to the hands of the Navy's Artifact Manufacturing Institute in September 1888.

It was such a little powder that was eventually developed by the Japanese, and was exploited and conquered by Japan, becoming the famous Gunpowder that later became the famous Gunpowder.

Its birthplace, Europe, was unable to solve the transportation problem, and instead conquered the more powerful nitroglycerin explosives, making high-precision and more stable, and picric acid explosives were eliminated from history.

With the current strength of the Ming Dynasty, it is too difficult to make nitroglycerin explosives; on the contrary, picric acid explosives can be produced in large quantities.

Zhu Youxiao had known about this matter for a long time and got the report. However, he did not expect that Bi Maokang's progress was so fast. Not only did he make metal fixed shells, but he also made mortars.

Judging from the posture next to you, there should be heavy artillery there.

Zhu Youxiao couldn't help but stand up, looked at Bi Maokang and said, "Since you're ready, let's try it out a few shots and see how it works."

After hearing this, Bi Maokang naturally did not dare to neglect and quickly said, "I will make arrangements right away."

"Go and go." Zhu Youxiao nodded and said.

In fact, Bi Maokang went down to prepare for a good arrangement. If he didn't arrange it, it wouldn't work. This experiment was originally an internal experiment, and everyone's attitude was still very relaxed and harmonious. He held that it didn't matter even if it failed. After so many years, they have not failed.

But the situation is not like this now. Your Majesty is here. Who would have thought that Your Majesty would come here at this time?

After arriving here, His Majesty still wanted to see them experiment. If something messed up would be bad.

If the experiment can be successfully made and His Majesty can see the results, it will naturally be a good thing.

Bi Maokang hurriedly made arrangements, and at the same time explained what he wanted to do, so that his subordinates could use more care and never make any mistakes. Fight for success and make His Majesty happy to see him.

Zhu Youxiao certainly knew what Bi Maokang was going to do, but he did not stop him.

After being an emperor for such a long time, Zhu Youxiao is very clear about one thing, that is, you should give your subordinates the opportunity to perform, and you should not let them not have the opportunity to perform. Then when they perform, give them some rewards and praise him.

Such things are very important to them, and this sense of honor is also very important to them. So Zhu Youxiao not only did not stop them, but encouraged them, sitting there quietly showing a look that I was looking forward to.

Soon, Bi Maokang arranged the matter.

Although Bi Maokang went to arrange things, he didn't allow him to do it for too long now. After all, His Majesty could not wait here for a long time.

Bi Maokang came back soon, and he said, "Your Majesty, you are ready."

"Okay, then come on." Zhu Youxiao nodded and said excitedly.

Take the telescope from Wei Chao's hand, and Zhu Youxiao sat and waited excitedly.

As for looking at it closely, Zhu Youxiao didn't mention it at all. The reason is very simple. His subordinates couldn't let him go, and it was just arguing when he asked.

Moreover, the mortar thing has just been made out now, and it is very dangerous, and maybe something will happen.

It’s better not to join in the fun at this time. If you blow yourself up, the consequences will be serious.

Zhu Youxiao attaches great importance to his own life. He does not live for himself, and he must not have any problems.

Bi Maokang naturally didn't know what the emperor was thinking, so he was thinking about showing it well now.

He was very excited and waved the flag of the order, making the people below prepare to fire.

And at this time, people in the distance moved.

They were in groups of two, carrying a wooden box in their hands, and came directly to the mortar.

Then they opened the box, took out the shells inside, and held them with caution.

After seeing this scene, Zhu Youxiao felt so excited.

Finally I saw something with a tail wing behind this shell!

After seeing this thing, Zhu Youxiao was so excited that he couldn't help himself.

Good stuff, good stuff!

Zhu Youxiao couldn't wait to see the final results of the experiment.

After taking out the shells, these people began to position them with their fingers and quickly adjusted the shooting angle.

The last man held the shell and put it directly into the muzzle. As he let go, the shell fell directly into the cannon barrel, followed by a bang.

Zhu Youxiao watched the shells spinning out in the telescope, and then landed fiercely on the ground not far away.

With a "boom", the shell exploded instantly.

After seeing this scene, Zhu Youxiao couldn't help but stand up excitedly.

Bi Maokang, who was beside Zhu Youxiao, jumped up with joy and shouted loudly: "It's done! It's done!"

Obviously, Bi Maokang was also very excited, and he couldn't help it.

After a while, Bi Maokang came back to his senses and quickly bowed to Zhu Youxiao and said, "Your Majesty, I am too excited. You have lost your etiquette before you, so I would like to ask Your Majesty to punish you."

Zhu Youxiao glanced at Bi Maokang, but didn't know what kind of performance he had.

But it doesn't matter. As an emperor, you have to endure these things.

Zhu Youxiao smiled and said, "I worked hard and made such a good thing for the Ming Dynasty. I have been persevering for so long. Now that the things are made, I will naturally be happy. I will write down your merits and I will definitely reward you well."

"Thank you, Your Majesty!" Bi Maokang said quickly, with a bright smile on his face and a very excited tone.

Didn’t Bi Maokang say the words just now just to let His Majesty reward him well? He had his own ideas. Now that His Majesty said this, everyone would naturally be happy.

"Let them let go." Zhu Youxiao looked at Bi Maokang and said, "Look at the power."

Of course, it is impossible for this thing to be just a shot, even if it is a test, it is impossible for it to be just one.

So the experiment started again, this time more than a dozen shots were fired together.

Looking at the dust bombed from the opposite side, Zhu Youxiao was so happy.

This is how much artillery is. What is the artillery before?

However, Zhu Youxiao did not interfere later. The experiments of such things have a overall process. The intensity of the tests and check where there is a problem. These things are not something that Zhu Youxiao can interfere.

If you just fired a few more shots just for the happiness of the emperor, you might be in trouble later. Zhu Youxiao naturally would not do such a thing. After all, everyone here is his treasure. One death or one injury will be a huge loss for him and the Ming Dynasty.

Bi Maokang arranged for people to continue the experiment. To what extent the barrel would not be able to withstand it and to what extent it would affect the development level. In short, all the experiments were carried out one by one.

But Zhu Youxiao doesn't need to accompany this kind of thing

Bi Maokang took Zhu Youxiao to another test site.

Here, Zhu Youxiao saw the cannon.

Unlike the previous artillery, this is a rear-mounted metal cannon, which uses metal fixed-mounted shells. And from the perspective of shape, this thing is the famous Miss France, and in later generations there is a more familiar name called Italian cannon.

This artillery is a French M1897 75mm artillery developed in France in 1897. Since this is the world's first artillery equipped with an anti-rear seat device, the artillery fire rate is as high as 15 rounds per minute, far exceeding other artillery of the same era, it shines in World War I, with production and sales volumes of up to 20,000.

During World War I, Italy had many such artillery. After World War I ended, they exported the eliminated artillery to China at that time. Because there were a lot of Italian on the artillery, this artillery was called Italian artillery in China.

This thing is actually very famous in China, but it is actually not the best artillery at that time. After all, there were many places in China at that time that could make artillery.

The production technology level of the artillery factory of the Jiangnan Manufacturing Bureau in Shanghai is already able to produce artillery of the same caliber and technical level.

The Krupp-style 14-fold 75mm mountain cannon that was successfully imitated in 1905 basically achieved national production of parts, and nearly 500 units were produced in total.

Even some visionary local warlord-led arsenals have produced larger caliber and more advanced artillery, such as the Chenyang Arsenal of Fengtian warlord Zhang Zuolin, which has produced 100 mm, 105 mm and even 240 mm heavy howitzers.

The Taiyuan Arsenal of Shanxi warlord Yan Xishan also produced 75mm and 88mm mountain cannons.

However, since the September 18th Incident, domestic arsenals have shrunk severely and their gun-making capabilities have declined significantly. We should have had better artillery, but at this time, it has not, making this Miss France, which is about to be eliminated, a very scarce thing.

But in the Ming Dynasty, Italian cannons were naturally extremely advanced. After all, this is a classic model. Many light cannons from later generations were modified based on this.

Just like the guns of ak47, it has developed into a gun family. But when everyone mentioned this series, it is still AK47.

Among the rear-mounted artillery, the French Miss is a hurdle that cannot be avoided. Just like among the bronze cannons, the Napoleon cannon is a hurdle that cannot be avoided.

So after the first artillery in the Ming Dynasty was established, it was this kind of French Miss.

Zhu Youxiao looked at Bi Maokang with an excited look on his face, but turned his head and asked with a serious look: "Can it work? If not, don't be too anxious."

The issue of artillery rifle has long been solved. The Ming Dynasty made rapid progress in this regard. The artillery barrel alloy material was solved well. Although some copper was still used, it was very small. However, in terms of artillery shells, copper still needs to be used in large quantities.

But what Zhu Youxiao was worried about was the artillery itself, so don’t blow it up again if you didn’t succeed. Zhu Youxiao doesn’t ask them to go on the ground quickly now. After all, the Ming Dynasty is still peaceful now, and it takes a lot of money to create large-scale production equipment.

To be honest, Zhu Youxiao xz has no money. The money the internal government has taken out is just enough to spend.

The annual harvest of grain and disaster relief made Zhu Youxiao very immense. The trade profits in the northwest also began to shrink. After all, those Mongolians have not had a good life in the past two years, and there is no surplus grain at home.

In other aspects, Zhu Youxiao's income is very small. Not to mention the income of the Ministry of Revenue in the court.

Zhu Youxiao has just equipped all his pro-military soldiers with flintlock guns in recent years, equipped with rocket launchers, and hand-crank light machine guns. Now if Zhu Youxiao has to change them, he will be a little powerless to be honest.

What's more, there is also a shipyard in Qingdao, which makes Zhu Youxiao feel a little distressed to burn money.
