On the fourth day of the eighth lunar month, Guo Wendong came to the arsenal again.

The research and production of pyrotechnics is related to the success or failure of the great cause of resisting the Qing Dynasty, and Guo Wendong is very concerned.

When he came to the research room, Song Yingxing was already working here, and after he successfully developed his own firecracker, he only took a day off and continued to work.

Guo Wendong said: "Mr. Song, thank you for your hard work!" Only one day off to work, you are still so hard in your youth, you don't want to go in your later life. ”

Song Yingxing sighed: "I have lived for more than 50 years before, and the technology I have studied has never been useful. Fortunately, you gave me a chance, and I have no regrets in this life! ”

Immediately thinking of some things, he showed resentment and said: "Kong Youde, a traitor, took refuge in Jiannu, let the Qing court master the technology of cannon casting, and let my Ming Dynasty's advantage in firearms disappear. I'll need to put a lot of effort into it, so I can come up with a better Hongyi cannon. Your Excellency, you also said that Jiannu may go south next year, so we have to hurry up. If I rest, my heart will be troubled! ”

In the fourth year of Chongzhen, Kong Youde defected from Dengzhou, Shandong Province to Jiannu, in addition to more than 20 Hongyi cannons were owned by Houjin, more importantly, he brought nearly 100 Portuguese gunsmiths, as well as a large number of elite gunners trained by Portugal.

On the countertop, there is a casting **, drawing the technology of casting guns, and on the other book, there is a technical manufacturing method of artillery, including the size of the artillery, the proportion of the barrel, the relationship between the wall thickness of the gun body and the fixed proportion of the caliber, etc.

At the end of the Ming Dynasty, the theoretical knowledge of official artillery manufacturing was introduced in the Tianqi period, perfected in the Chongzhen period, and applied to the Hongyi cannon, and the iron casting method still came from the local metallurgical technology.

Guo Wendong read the content carefully, and it was quite professional.

Song Yingxing said: "My lord, the cannon technology mastered by Jiannu now is like this, and Da Ming also uses this method to cast cannons. You asked me to study better cannons, and I will step up my research on this technology. In addition, I also need to recruit craftsmen who know how to cast cannons in advance, so that it will be convenient for me to guide after my research is successful. Before the cannon is researched, you can let it cast the Tiger Squat Cannon. ”

If you are a complete novice, it will take a lot of effort to guide them in the production of artillery.

The tiger squat cannon is equivalent to a light mortar, can also be regarded as a shotgun, the weight is only thirty or forty pounds, each launch can be loaded with 5 money weight of small lead or small stones 100, with a weight of 30 taels of large lead bullet or large stone bullet on the top, when the bullet flies out.

This is also the main artillery that Guo Wendong planned to equip with, and the combination of tiger squat artillery and longer-range artillery formed a double line of defense against the Qing army.

Then there are several rooms in the flintlock pistol making area, each dedicated to one of the processes, and equipped with more than a dozen craftsmen, who are instructed in the production method by the original old craftsmen.

For example, there are people who make flint, and there are people who make projectiles.

Coming to the final process, the final assembly area, the old craftsmen were explaining to the new craftsmen.

"You have to put the flint like this first, then twist it here and press it tightly, and then ........."

The old craftsman, who is about 60 years old, is explaining and demonstrating with his own hands, and the new craftsman is listening and watching carefully.

After seeing Guo Wendong coming, the old craftsman stopped and saluted Guo Wendong: "See the guerrilla general." ”

When the others learned of the identity of the comer, they saluted in unison.

Guo Wendong looked at the old craftsman, his hair and beard were half gray, but his spirit was very strong, and said: "Old man, it is rare to be able to do a good job at the age of the sixtieth birthday!" ”

The old craftsman smiled and said, "Hi! The two Song adults are not also the age of the sixtieth year, they can do things, and I can do them too. I used to make bird guns and three-eyed guns for the government, and then I learned to make self-made fire guns, so it was not so difficult. Besides, working here is very good, and while the body is still strong, earn some money so that your children and grandchildren can live a better life. ”

Song Yingsheng, who accompanied Guo Wendong, said: "Master Liu used to specialize in firearms in other workshops in the Ming Dynasty, and he has 40 years of experience and is skilled. The production technology of self-generated fire guns is the most exquisite in Master Liu. ”

A master like this gives a lot more silver than an ordinary craftsman.

Guo Wendong encouraged everyone again, and then walked to the next room.

This room was used for the storage of finished products, and there were already more than twenty flintlock pistols on the floor.

Guo Wendong picked up one of them and looked at it.

Song Yingsheng said: "My lord, every process and every part is made in accordance with a unified standard. Each process is inspected by someone. ”

Guo Wendong's arsenal, production and management system has the prototype of a modern factory.

A person who specializes in inspecting parts and finished products is called a quality inspection department in modern times.

Song Yingsheng said: "The self-made fire guns will be stored in the warehouse and registered in the register after they are checked that there are no problems." ”

Guo Wendong picked up a flintlock pistol and went to the flat ground to test shoot a few shots, and there was basically no problem.

Mass production of flintlock pistols has begun, and it will soon be ready for the troops.

After the inspection, Song Yingsheng said: "My lord, the monthly salary we give is high enough, it is very convenient to recruit craftsmen, and in a later day, there will be dozens of craftsmen in the next batch." ”

In the hot weapons area, there is also a casting area, where all kinds of steel objects are cast, including gun barrels, metal parts, gun barrels, etc.

Guo Wendong entered the workshop to inspect, and the blacksmiths used that professional technique to make fine gun parts.

Song Yingxing is a great talent, and Song Yingsheng is also not bad, he manages the arsenal in an orderly manner, and it has been proved through practice that he is a managerial talent.

However, Song Yingxing is not young, and he needs to find suitable personnel to pass on the technology.

Guo Wendong has already considered this, but this is not an important matter, he must first resist the Qing army that will go south next year, so that he can have a future, otherwise just like the original history, the catastrophe will come, and the Ming Dynasty will be completely finished.

Forbidden City, Harem.

On the afternoon of the fourth day of the Lunar New Year, Zhu Yousong was frolicking with the harem women again.

After going crazy for a while, Zhu Yousong got tired and finally stopped.

"Little Guizi!" Zhu Yousong shouted.

"The slave is here!" The accompanying eunuch Xiao Guizi came to the emperor.

Zhu Yousong looked at Xiao Guizi and asked, "Yesterday, you took a pill of elixir, and you were safe and sound!" ”

Xiao Guizi said: "Your Majesty, the guerrilla general said that it would be very exciting to eat the elixir, and the slave maid has been eating the elixir for a day, and I still can't feel any difference." ”

Zhu Yousong laughed, causing the concubines and palace maids present to laugh too.

Zhu Yousong said: "You have been purified, where can you still be strong." This elixir is non-toxic, so I can try it with confidence. ”

He ordered someone to take Viagra and take one pill.

In less than half an hour, Zhu Yousong became excited and began to go crazy.
