As early as when the soldiers of Qianhusuo returned to the capital from Shanxi, Liu Hongjian sent people to Shanhaiguan, and the three color-eyed people, a captain, a mercenary, and a shipwright, not only understood the European pattern, but also had skills, and they were of great use in the next plan.

Let's say that these three foreigners were gradually abandoned by Liu Hongjian in Shanhaiguan, and there has been no news for several months, and they thought that the chief soldier had forgotten them, and they were very happy to get the news that Liu Hongjian was going to take them to the capital.

You must know that they have been wandering in Daming in the past few years, in order to go to the capital to seek a future, but unfortunately they were abducted and deceived along the way, and they went to the front line of Shanhaiguan in a daze to drink the cold wind for a year.

Fortunately, the chief soldier took pity on them, not only gave them a place to live, but now he wants to take them to the capital to mix, which is the place they dream of, escorted by the brocade guard, and the journey was smooth, until the three of them came to the capital Houfu, there was a feeling of dreaming.

"Thank you, Honorable Lord, for your kindness, Juan González thank you!"

Seeing Liu Hong, who was dressed in a unicorn suit, gradually walked out of the inner courtyard, Juan organized a discourse and bowed to Liu Hong, and the other two hurriedly followed.

"Hahaha, welcome to beijing! my friend！ Liu Hong gradually stepped forward and shook hands with them, which made the three of them a little flattered.

"My lord, I don't know if there is anything we need to do?" Juan understands that if he wants to have a place in Daming, then he must prove his ability.

"Not busy, not busy, it's cold outside the house, let's go, go inside and talk!" Liu Hong gradually went to the middle hall first, and the three of them followed suit.

"I remember that one of you knows firearms, I wonder if you have ever seen this kind of firearms?" Liu Hong gradually took out the blueprint of the flintlock pistol and handed it to Juan.

Juan took it and took a look at it, then handed it to Carl, who was a fanatical warfighter and interested in everything related to the war.

"My lord, this is a ramming rifle, which the Royal Netherlands Navy is already equipping, and several other countries in Europe are also equipping." Karl's eyes lit up when he looked at it.

"My lord, I can help you improve this gun!" Karl is not shocking and dies.

When Carl and Schulz came to Daming, they still carried one such gun, but within a few days, they were snatched away by the kind and simple people of Daming.

Listening to Carl's words, it was Liu Hong's turn to be surprised, originally he thought that the three of them had seen flintlock pistols at most, who knew that people had not only seen them, but also improved them, and what surprised Liu Hong gradually was that Europe had begun to be equipped with flintlock pistols on a large scale.

And Da Ming is still holding the three-eyed fire gun from decades ago.

On the basis of the revolver musket, the ramming flintlock pistol removes the clockwork steel wheel and ignites the gunpowder with the flint impact, which improves the shooting accuracy and firing rate.

The single flintlock pistol is still a front-loading gun, and special tools are required for the projectile assembly, and because they are all made by hand, the muzzle accuracy cannot be guaranteed.

When loading the projectile, it is necessary to put the projectile into the muzzle, use a wooden hammer to feed the bullet stick, and push the gun into the chamber, which is very time-consuming, and on the battlefield, it means wasting life.

In a fortuitous experiment, Karl found that the projectile was wrapped in a sheet of linen or deerskin soaked in grease, loaded into the muzzle, which reduced friction, not only increased the reloading speed, but also played a breath-holding role, which improved accuracy and increased the range.

Liu Hongjian was very pleasantly surprised, but now there are only talents and drawings, and there is no space, so it is imperative to build a R&D center.

After settling the three of them, Liu Hong gradually saw that it was still early, and prepared a horse with a bull and a mallet and went straight to the household.

He needs craftsmen, blacksmiths, stonemasons, carpenters, etc., and the household department is in charge of the household registration of the craftsman's household, and he needs the household department to help issue notices and recruit craftsmen for the entire Ming Dynasty.

Although the most skilled craftsmen are all in the core departments such as the War Bureau under the Ministry of Industry, in order not to affect the progress of the Ministry of Industry, Liu Hongjian still plans to recruit from the local government, after all, it is not a glorious thing to dig people into the corners.

With Chongzhen's approval, the Hubu Shangshu was not ambiguous, and directly ordered people to issue a recruitment notice in the Beizhili area, requiring all registered craftsmen to report to the Hubu within five days.

At Liu Hongji's request, a short sentence was added at the end of the proclamation, "The chosen one has moon silver."

PS: My friend got married, I was stunned, it's a little short, everyone, Haihan, come back on National Day to make up for you a little more.
