(second update)

There will be a third update later, but it will be after midnight.

Potassium nitrate, sulfur, and charcoal powder are mixed and are called black gunpowder.

This kind of gunpowder is extremely intense when burning. If it is burned in a closed container, a large amount of gas and heat will be generated, resulting in an explosion. If the amount of carbon is simply based on nitrate and sulfur, the gunpowder produced is mainly burned and produced thick smoke, and the power it produces during explosion is naturally not great.

Yu Yin hesitated for a moment and said softly: "Uncle Ling, why is there too little charcoal powder?"

"What's the use of asking for a lot of charcoal powder?" Ling Zhen couldn't help but wonder, "Character powder is just to help it burn, but to ask for so much is a waste."

Yu Yin didn't know how to persuade Ling Zhen, and said immediately: "Why don't you give it a try?"

Since the previous test failed, something must be wrong. Why not change the method and maybe succeed?"

"this……"

Ling Zhen hesitated.

In fact, in his opinion, the amount of charcoal powder is irrelevant.

If someone else persuaded him like this, Ling Zhen would not spit it on the other person's face.

But Yu Yin advised him like this, but he had to think seriously. As Yu Yin said, since he failed many times, why not change his method?

"Uncle, if you try again, you might as well do it in the form of one sulfur, two nitrile and three carbon powder."

Ling Zhen laughed: "One, two, three, this is so easy to remember... Since Brother Xiaoyi said that, I will try the last time."

"Uncle, I have another suggestion."

"explain!"

"How big is it to test the gun now?"

Ling Zhen thought about it, gestured with his hands and said, "It's almost a circle bigger than a baby's head."

"If, I mean...If...If my uncle succeeded in following the method Xiao Yi said, could he make this shot smaller?"

"Smaller?"

Ling Zhen only heard people say that the bigger the cannon, the better.

But this is a little smaller, how small should it be?

"It's one size smaller than my fist."

Yu Yin stretched out his hand and gestured, "It's made smaller, mainly for the convenience of carrying... It's not about power like a cannon, just in a small range, for example, the distance between the two of us can produce an effect..."

What Yu Yin thought about was the purpose of later generations of grenades.

After all, Ling Zhen is an expert in this field. After hearing Yu Yin's explanation, he nodded and said, "I probably understand what Xiao Yi means. But this is not easy to do! I don't know if it can achieve the effect Xiao Yi said, and I don't know whether it can be successfully produced according to what Xiao Yi said. However, I will give it a try...

But there is a problem: it will inevitably cost a lot of money to try it out like this.

Before, I tried the artillery for most of the time, and asked the craftsmen to do private work... I still succeeded in a few times, but if I had too many times, it would be a little troublesome. Also, if I really did the artillery as Xiao Yi said, I wouldn't be able to explain it to the military weapon supervisor, and I would have to spend more money.

If there are fewer ones, you can withstand it.

But if you follow what Xiao Yi said, I'm afraid it's..."

The Imperial Camp of Moutuogang is a workshop affiliated to the Military Artillery Supervision specializing in the generation of gunpowder and processing of leather artillery.

The subordinates of the Military Artifact Supervisor are divided into ten workshops, each performing its own duties and have different divisions of labor. In the Imperial Camp, five hundred leather artillery cannons are required to hand over every day, and they are also responsible for the gunpowder task of supplying the other two workshops. For small-scale test guns, the Military Artifact Supervisor can turn a blind eye. But if it is like Yu Yin's statement, it is necessary to fundamentally change the ratio of gunpowder and the production process... This can only be carried out in private, and it requires countless repeated experiments.

The expenses in this...

Even if Ling Zhen had 200 people ate the salary, he could not hold on.

When Yu Yin heard this, she couldn't help but frown, "Uncle, how much does it cost per month?"

"I can take some paths and save some money.

However, the craftsmen need to pay separately, and they will have to spend 200 to 300 yuan a month, but it is difficult to report it."

When Yu Yin heard this, he breathed a sigh of relief.

"If it is only two or three hundred coins, Xiao Yi will take it out."

I thought it would take a few thousand guan... If this is the case, Yu Yin would really not be able to hold on. It was only 200 to 300 guan, and although there was pressure, it could still hold on.

Ling Zhen looked at Yu Yin in surprise, shook his head and smiled, "Xiao Yi is so heroic... Since that's the case, I will start preparing. But recently, I'm afraid of how much kung fu! The Military Arts Supervisor just ordered me to add 200 caltrop cannons and 1,000 bows and gunpowder arrows every day. If I really want to free up my hands, I'm afraid that it will be possible to do it after the spring of the next year."

The military weapon supervisor's armory can be responsible for the production of firearms.

According to the regulations issued by the Privy Council, the Armament Warehouse needs to produce 7,000 crossbow gunpowder arrows, 10,000 bow gunpowder arrows, 3,000 thorn gunpowder gunpowder gunpowder gunpowder gunpowder gunpowder gunpowder gunpowder gunpowder gunpowder gunpowder gunpowder gunpowder gunpowder gunpowder gunpowder gunpowder gunpowder gunpowder gunpowder gunpowder gunpowder 3,000 skin gunpowder gunpowder 3,000 skin gunpowder gunpowder 3,000 skin gunpowder gunpowder 3,000 skin gunpowder gunpowder 3,000 skin gunpowder gunpowder 3,000 skin gunpowder gunpowder 3,000 skin gunpowder 3,00

"Uncle, why did you suddenly have so many more assignments?"

The daily output of military weapons supervisors has a fixed quota and no special things, and it will not increase.

Suddenly, if you ask for so many firearms to be increased, something must have happened...

Ling Zhen sighed, "Xiao Yi may not know that the day before yesterday, on the day you moved, the Privy Council received the request of the Governor of the Eternal Army, and needed 100,000 crossbow gunpowder arrows and 300,000 bow gunpowder arrows, as well as 300,000 trough trough cannons and 20,000 leather gunpowder cannons.

Moreover, the governor of the ever-winning army was very close, so the official family ordered the Privy Council to resolve the problem as soon as possible.

The Privy Council put this matter on the military weapon surveillance again. The military weapon surveillance turned its head and asked me to wait for the work... You want to hand over so many firearms before the New Year, and all workshops have to work, and even my imperial camp is not spared."

"The governor of the Eternal Conquering Army... Could it be that Pharmacist Guo?"

Ling Zhen looked at Yu Yin in surprise, "How come Xiaoyi also knows him?"

However, Ling Zhen was relieved immediately, "Xiao Yi had no contact with him, and he had many friends with him. It was not uncommon to know about Pharmacist Guo.

That’s right, it’s the Yanshan Tongzhi Yaoshi Guo.”

Yu Yin's heart suddenly stumbled.

What does Pharmacist Guo want these many firearms to do?

Little did he know that after he surrendered to the Song Dynasty, Guo Yaoshi was very favored by Emperor Huizong. He flew across Bohu and did whatever he wanted. The prefect of Yanshan Wang Anzhong was "unable to control it, and he was willing to serve it." All weapons, armor, horses and horses were given priority. Guo Yaoshi sent people to do business in various states, earn money, and use it to make friends with the powerful...

Ling Zhen sighed, "The official treats Guo Yaoshi very well, but this person has a wolfish ambition."

"How do you say this?"

Ling Zhen whispered: "I heard that Guo Yaoshi's always-winning army is all in the 'left-sided lapel' outfit.

Xiao Yi knows what this "left-sided" outfit means? It is the costume of the Liao people. Now he has surrendered to the Song Dynasty, but he wears the clothes of the Liao people. His heart can be seen. Before, Lord Yan Ying impeached Guo Yaoshi with the left-sided outfit. He must have a different intention, but was scolded by the officials, making him think of his mistakes behind closed doors. What else is it that Guo Yaoshi will not forget his homeland, and he is a loyal minister... The officials should make him surrender with a kind heart, saying that Guo Yaoshi will never rebel against the Song Dynasty. After hearing about this, I was so cold-hearted.

I have a friend, and now I am under the tent of the Xuanfu Envoy of Hebei.

The ever-winning army now has 50,000 soldiers and 300,000 rural soldiers... But the officials have no precautions against this person."

When Yu Yin heard this, he immediately took a breath of cold air.

He probably knew Guo Yaoshi, but he didn't know much about this person.

Listening to Ling Zhen’s words, this guy is simply An Lushan during the reign of Emperor Xuanzong of Tang.

The head of Emperor Huizong sometimes looks very strange.

There are also generals who are good at fighting in their own corporal positions, but they are afraid to be wary of... I feel so relieved about a surrendered general, so why can he surrender with a kind heart? This kind of thing can only happen in the novel! How could a guy who refuses to change his clothes and really serve the Song Dynasty? This Guo Yaoshi is also a hero with a three-family slave.

But what can Yuyin do?

Even a small gunpowder bureau like Ling Zhen can see clearly, but Emperor Huizong couldn't see clearly.

I'm afraid that it's not just the problem of Emperor Huizong. Could it be that no one can see clearly in the civil and military affairs of the court?

The theme of the second issue of the Song Dynasty Weekly suddenly appeared in Yu Yin's mind.

Perhaps, I should remind people about this problem of Pharmacist Guo!

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

"Uncle, why didn't there be any raids?"

Yu Yin and Ling Zhen were talking for a long time, but suddenly remembered something.

Didn’t it mean that the earliest tubular firearm in history appeared in the Song Dynasty?

But from the moment, whether it is the skin cannon, the trunk cannon, or even the thunder cannon, they are not the kind of "cannon" that Yu Yin is familiar with, but a shell more similar to that used for throwing. So, where is the thunder gun? Where is the real cannon?

"What kind of musket?"

Ling Zhen looked confused.

Is there no 'supramite'?

Yu Yin was also stunned, closed her eyes, and tried to recall the few memories left in his previous life.

Or, the rifle gun has not appeared yet?

After all, he was born in music, so Yu Yin really didn't know much about the history of the development of this kind of firearm.

The rifle gun was filled with a giant bamboo tube as the body, filled with gunpowder and bullets. After igniting the gunpowder, the bullets were sprayed out of the giant bamboo tube with a range of about 200 meters. This weapon did appear in the Song Dynasty. But it was not in the Northern Song Dynasty, but in the second year of Shaoxing in the Southern Song Dynasty, which was around 1132 AD. The inventor was Chen Gui, a famous minister of the Southern Song Dynasty.

This person once wrote "Records of the City".

However, Chen Gui was still the county magistrate in Anlu County, Suizhou, and it was even more impossible for the sudden musket to appear.
