As soon as the old slave received His Highness's request, he immediately adjusted the workshop plan. The old slave gathered all the blacksmiths in the workshop together to serve His Highness.

Your Highness, most of the time spent on making the barrel is thinning wrought iron. The old slave gathered the blacksmiths together and made wrought iron together, so that the speed could be increased several times.

The old slave prepared several more suitable steel columns and used them alternately, which shortened the time required to cool the steel columns. Several groups of blacksmiths worked together to make these two three-layer barrels in two days.

As for the single-layer and double-layer barrels, this is an in-house stock and does not need to be made separately. Zhang Yixian respectfully introduced the process of making the barrel to King Xin, without the slightest intention of showing merit. But listening to the various details he introduced, you can know how much effort he has put in in the past two days.

Zhang Yixian knows the power of the young master in front of him. The favor received by King Shin is unique in the entire Apocalypse Dynasty. This exclusive favor shocked the inner servants far more than the foreign ministers.

When Zhang Yixian knew that the barrel of the gun was wanted by His Royal Highness King Xin, he immediately mobilized all the blacksmiths in Wang Gong's factory, just to make a good impression in front of His Royal Highness King Xin.

I can't help it.

Wang Gongchang, Zhang Yixian didn't want to stay longer for a day. Although there is a lot of oil and water in the Wang Gong factory, every time he sees the gunpowder in the large warehouses in the factory, Zhang Yixian is frightened. No matter how much oil and water you fish, you have to have a life flower.

During this time, Zhang Yixian was trying his best to transfer out of Wang Gongchang. If he can catch the line of King Xin, it will not be a trivial matter to leave Wang Gong's factory.

"What's your name?"

After listening to Zhang Yixian's introduction, Zhu Youzhen really had a good impression of him. In such a short period of time, a large number of blacksmiths were coordinated to successfully create two 3-layer barrels, which shortened the construction time by 5 or 6 days, which is rare in this era. What's more, Zhang Yixian obviously has the intention of moving closer to the organization, and this kind of talent still needs to be taken in.

"The old slave Zhang Yixian knocked to see His Royal Highness King Xin."

Hearing King Xin ask his name, Zhang Yixian was overjoyed and simply bowed down.

His Royal Highness can ask his name, which is great news for Zhang Yixian. As long as you can put a number in the heart of His Royal Highness and leave a little impression, the hard work of these two days will not be in vain.

"Well, get up, no need to be polite. That, Zhang Yixian, did you bring the gunpowder for the test barrel? Zhu Youzhen asked very dryly.

Well, let's just ask this Zhang Yixian to test the gun together. In this way, he, the eunuch in charge of Wang Gongchang, could have the most intuitive impression of this kind of experiment.

On the martial arts arena of King Xin's Mansion, according to Zhu Youzhen's requirements, a safety bunker was built with sandbags.

However, this bunker is not for people, it is for the barrel of a gun.

The bunker was built by Zhu Youzhen after the scene of dismantling the bomb in the film and television film of his previous life. In this kind of bunker, even if the barrel of the gun is blown up, it will not cause damage to the surrounding environment and personnel.

The experiment begins

Under the auspices of Zhu Youzhen, the charge test of the barrel was carried out step by step.

One money, two money, three ......money, first two single-layer barrels exploded at 5 money, 5 cents and 6 money. Subsequently, the two double-layer barrels also exploded when the charge was about 1 tael and 2 yuan, and only 3 layers of barrels were still being charged. When the three-layer barrel experiment reached 2 taels of charge and was still fine, Zhu Youzhen terminated the experiment.

"Zhang Yixian, according to this double-barrel method, I will send 10 new barrels to Guda." Zhu Youzhen instructed Zhang Yixian with a happy face, and at the same time secretly applauded the craftsmanship of Wang Gong's factory in his heart.

He didn't expect that the double-layer barrel made by Wang Gongchang could reach the limit charge of 1 tael and 2 yuan. By this quality, the double-layer barrel was enough to withstand a charge of 5 cents, and there was no need to strengthen to 3 layers of barrel at all.

"Yes," Zhang Yixian, who was stunned by the results of the experiment, replied casually, and then he replied loudly: "The old slave obeys His Highness's instructions. ”

While leaving, Zhang Yixian muttered: "Okay, this way is so good, why didn't I think of this way of testing guns?" ”

When Zhang Yixian sent 10 barrels as promised, Zhu Youzhen remembered him deeply.

Because of the different calibers of these 10 barrels, it is impossible for Wang Gong's factory to hide them in stock. can use three days to create 10 gun barrels, Zhang Yixian's coordination and organization ability can be seen, this is definitely a talent! Worth taking in.

"Yi Xian, you come with Gu."

Hearing King Xin's greeting, Zhang Yixian's heart was extremely hot, and he finally registered in King Xin's heart.

The results of the experiment with 10 barrels made Zhu Youzhen very satisfied. The worst quality of the barrel, the charge also exceeded 1 tael 1 penny. Based on the data from this experiment, Zhu Youzhen can be convinced that the double-layered barrel is enough to shoulder the heavy responsibility of the tunnel starting gun.

In this way, only the bolt and butt part of the tunnel gun using a double barrel are considered new technology, and the others are mature technology, so that the output of tunnel guns can be greatly increased.

The experience of this experiment also made Zhu Youzhen understand that the craftsmen of the Ming Dynasty are indeed doing things based on experience. They don't even do basic physical experiments with new guns, and they take things for granted based on past experience. This way of working will inevitably make the new gun coarse and clumsy, and the new gun with crude benzene will inevitably not meet the needs of actual combat. It's no wonder that so much time has passed, and Daming's new gun has not yet appeared.

Of course, the craftsmen can't be blamed for this. The manpower and material resources required to do a large number of physical experiments are not provided and mobilized by craftsmen, and the root of the problem lies in the management class.

But why don't managers like Zhang Yixian do it?

It's very simple, Zhang Yixian can't get any benefits from what they do, how can they go to trouble themselves.

It's very simple to make people like Zhang Yixian move, and it is spontaneous.

It's nothing more than "if you are good at the top, you will follow it at the bottom." ”

In this era, we still need to look at the needs of the superiors!

In this era, as long as the superior really wants it, the execution of the subordinate is still very fast.

Look, Zhang Yixian is not the best example.

"Yi Xian, build a new barrel according to this standard. After the highest charge is 1 tael 1 money test, those who pass will be rewarded, and those who fail will be punished. If you don't believe it, can't this gun be made quickly and well? Zhu Youzhen smiled and instructed Zhang Yixian.

Thinking of the memories of his previous life, Zhu Youzhen added with a smile: "Do it well, Lone is very optimistic about you." ”

Wang Chengen's time to prepare materials made Zhu Youzhen see the importance that Daming attached to armor. 200 pairs of cotton armor, Wang Chengen took more than 10 days to prepare neatly, and this was still under the condition that Gonggong Wei gave the green light all the way.

In this era, armor is really king!

The Ming court's management of armor far exceeded that of other ordnance.

"However, when my tunnel pistols are equipped in batches, this world should change." Zhu Youzhen looked at Zhang Yunyi's convoy in the distance and forcibly suppressed the restlessness in his heart.
