Wei Zheng frowned, and stepped forward: "Your Majesty, the minister thinks it's inappropriate, the Central Plains has just been pacified, the Lingnan road is far away, the terrain is treacherous, and the supply of grain and grass is difficult. Moreover, there is a plague of miasma, and large troops cannot be stationed. Moreover, whether Feng Ang rebelled or not has not yet formed a fact, and it is not appropriate to mobilize the army now. ”

Li Shimin looked at Wei Zheng, and the good mood just now suddenly disappeared. Pointing to a stack of folds: "No rebellion?" So what's going on with all these twists and turns? Now that there is an endless stream of people accusing Feng Ang of rebellion, how can it be said that the fact of rebellion has not yet been formed? ”

"If Feng Ang rebels, he will inevitably attack neighboring states and counties, and divide his troops to occupy dangerous places. It has been a few years since he was accused of rebellion, but the Feng soldiers and horses have not left his territory, and it is possible for the barbarian land to support the army and respect itself, as for the rebellion, Weichen thinks that it is not. Wei Zheng thought for a while and replied: "Since the state governments suspect that the Feng family is plotting rebellion, and Your Majesty does not send envoys to appease them, the Feng family is afraid of death, so they dare not come to the imperial court. If His Majesty had sent an envoy to show him sincerity, Feng would have been glad to be spared the calamity, so that he would have to obey without having to work the army. ”

Li Shimin thought about it for a long time, and felt that it was also reasonable, but because of the matter of the navy, the blood in his heart was boiling, and he couldn't wait to go to war immediately, raising his eyebrows. Now that I think about it, I was also impulsive, so I waved my hand and stopped talking.

Qinghe Cui's house in the back mountain, Cui Yanzhuo looked at the fishing old man in front of him and said nothing. In a moment, another carp landed on the shore with a flick of the fishing rod. The old man turned his head to look at Cui Yanzhuo, who was guarding the side, and said slowly and methodically: "Fishing is not about catching fish, nor is it about casting nets, you must first have bait, patience, and more importantly, you must understand the habits of fish and master the methods of fishing." ”

Cui Yanzhuo hurriedly responded: "The child has been taught. ”

"The second child of the Li family became the emperor, he was ambitious, and he was reforming the land and running the school, and he was menacing. However, it is also to calm the people's hearts and sit firmly in the world, as long as you understand their intentions, it is not difficult to use them when the time comes. ”

The old man nodded and continued: "What just happened, don't take it too seriously, after all, the emperor is young, the prince is young, they are still young, our purpose is to inherit, peace and prosperity, and the development of cooperation with the royal family is the best choice, this time, God favors, just let us catch up with such a thing, can do compromise, in order to be invincible." ”

Cui Yanzhuo nodded yes, the old man stood up from the maza, patted the placket of his clothes, and sighed: "It was estimated that the Li family except Li Er was all mediocre, but I didn't expect that there would be a shrewd Li Chengqian, I, Cui Wenli, have lived for such an age, and it is the first time I have seen such a genius, which is simply a natural asset." The skill of this personality is amazing, the layout of governing the country and the country is far-reaching, and he is good at calculation at a young age, no matter what involves this person in the future, he must not be guarded against. In the future, you can take the initiative and get closer to him, as long as you have a little benefit, we will not be able to use it. ”

"Then how should I explain the matter of Zheng Wenxuan?" Cui Yanzhuo thought about it, but couldn't help but ask.

"It's just a fool, I've already discussed with the Zheng family, let him go to Silla, anyway, it's a scourge, let him go to the land of barbarians, there, whoever he wants to harm, he will be harmed, and when the time comes, he will be killed, and he will be killed. The Zheng family is already in a hurry because of Zheng Tao's matter, if the Zheng family is destroyed, if lucky, Zheng Wenxuan may not be able to leave a bloodline for the Zheng family in Silla. It's the same with our Cui family, those unsuccessful squirts, throw them there for me, and fend for themselves. Listening to Cui Wenli's words, Cui Yanzhuo's heart trembled, and a chill rushed down his spine to the top of his head.

……。

"After the new rain in the empty mountains, the weather is late in autumn. The bright moon shines among the pines, and the clear spring stone is upstream. The bamboo noise returns to the Huannu, and the lotus moves the fishing boat. Feel free to rest in spring, and the kings and grandchildren can stay. Listening to the sentence plagiarized by the prince, Li Wujie was indifferent, and Li Chengqian couldn't help but be embarrassed.

Secretly glanced at Li Wujie, seeing that people were concentrating, holding a quill in one hand, skillfully playing abacus with the other, sorting out the accounts, and then looking at his pig brother's appearance, he couldn't help but hang his head.

This is the second day of returning to Luoyang, thinking about the purpose of my return and what I am about to do, I can't help but feel better again. His arsenal was finally ready to open, because the simplest mortar was about to be released, of course, quietly in trial production first.

The mortar is composed of four parts: the gun body, the gun mount, the mount and the sight. The arsenal is divided into three parts, the first is the casting assembly processing plant, including the gun body and base processing plant, which is mainly responsible for casting and building the gun body, inspecting the quality of the gun body, and classifying it according to the caliber, and then sending it to the warehouse of the assembly plant. The gun carriage processing plant specializes in the processing and inspection of the various parts of the gun carriage, and at the same time manufactures spare parts for the sights, which are finally sent to the warehouse of the assembly plant.

There are also shell casing foundries, which use special molds to cast shell and grenade casing parts and firing pins, excitation spring primers and other accessories. After passing the inspection, the products are sent to the warehouses of the ammunition assembly plant.

The rest is a gunpowder processing plant, which is divided into primer fire charge and propellant, explosive. The primer consists of a brass shell, a brass fire table and a special fire cap. The structure of the special fire cap is basically the same as that of the ordinary fire cap, which is also composed of a shell, a firing charge and a cover, and the assembly relationship of the primer is to first load the fire cap into the primer shell, and then press the fire table, and finally seal a complete primer.

Hair spraying drugs are basically developed according to the proportion of potassium chlorate, sulfur, realgar, diantimony trisulfide, etc. Antimony trisulfide is produced from stibnite, which in those days was nothing more than a cosmetic product that people didn't know was toxic.

There are two types of propellants, one is black powder and the other is nitrocellulose. The main reason for using black powder was also Li Chengqian's own trouble. The main thing is to verify how big the difference between the two is. Gain experience for future production. The propellant is refined to form granules, which are then sent to the inspection workshop for inspection, and finally, to the charging workshop.

The explosives are mainly ammonium nitrate explosives and black powder, which are excited by mercury thunderate or potassium chlorate. However, the production process of mercury thunderate, nitrocellulose, nitroglycerin and picric acid is immature, difficult to prepare, and the output is not large, which limits the development. As the saying goes, if you have a gun, you must first have a bullet, and if you have a bullet, you must first have medicine. The process problem is like a rope around the neck, and the prince of Le is out of breath.

Finally, there is the assembly plant, which is divided into two parts, one for the assembly of guns and one for the assembly of ammunition. Basically, each branch is responsible for a part. Dedicated management, extremely strict security. The factories do not understand each other, and only pass on information through the specialized personnel of the local branch camp.
