After I was reborn, I became a plug-in for the country

That night, Dai Zi was ordered to rush back to the capital from Jingshan, and went to the palace overnight to have an audience.With his travel-stained appearance, it can be seen that he is also extremely anxious.

When Kangxi saw him in Zhaoren Hall, seeing his slightly slovenly appearance, he couldn't bear it.He likes courtiers who are down-to-earth. Dai Zi's attitude of ignoring everything after being obsessed with official affairs is still in line with his expectations of courtiers.

But the attitude is the attitude, thinking that he doesn't know how to do things flexibly, and keeps urging him repeatedly, Kangxi still wants to get angry.He was very angry when he got angry, and he scolded Dai Zixiao for half an hour before he barely finished his lesson.

Dai Zi stood with his hands down and listened silently for a long time.It wasn't until Kangxi had nothing to say that he choked out a sentence: "The emperor taught me that."

Kangxi felt a little comforted, and was about to praise him again, and when he fully carried forward the spirit of wanting to make up a sweet date immediately after a slap, he heard Dai Zi ask: "Your Majesty, where is Your Highness the Crown Prince now? I have a few questions, and I would like to meet them face to face." Ask Your Highness for clarification."

Kangxi: "..." Why couldn't I just waste my time with this fellow?

Next time I should ask someone to beat him up first!

Seeing that the clock in the hall had already pointed to Haishi, it was getting late outside, and the solid eyes below him still had a face of "I will not give up if I don't see the prince tonight", Kangxi helplessly raised his forehead, "Let someone go to Yuqing Palace to ask if the prince has gone to bed?" .If not, call him."

Liang Jiugong asked the little apprentice to run errands, and he brought another cup of tea to Kangxi, "Your Majesty, calm down, Mr. Dai is also dedicated to business."

Dai Zi took a special look at Kangxi's face again, and after reading it, he was even more puzzled, the emperor was angry just now?

The hall was quiet for a while, Kangxi glanced at Dai Zi in distaste, then ignored him, and went to look through the brochures by himself.

Half a moment later, Yinfeng was late.When the little eunuch went to pass the decree, he had just taken a bath.He got dressed in a hurry and came over.

He first saw Dai Zi standing upright like a sculpture, and he probably understood why Khan Ama summoned him late at night.

Even if he understood why, he just pretended not to see it, and knelt down to greet Kangxi: "Khan Ama Wanan. It's so late, why haven't you rested yet?"

"Get up." Without lifting his eyelids, Kangxi pointed to Dai Zi and said, "Ask him what's the matter."

"What's the matter, Mr. Dai?" Yinfeng asked politely.

Dai Zi turned around and bowed to Yinfeng, "Your Highness, I have seen the method of making the new-style firecracker you wrote, and there are still a few things that are unclear. I hope Your Highness can advise."

Yinreng glanced at Kangxi's face, seeing that Khan Ama didn't stop him, he laughed and said, "Where is it unknown, sir?"

Dai Zi took out the blueprint and the rules written by Yinfeng from his sleeve, and asked for an order: "Can the emperor reward one of the ministers' desks?"

Kangxi's anger that had just subsided came back again.This guy is not only pushing his inch, he is simply pushing his inch!

Just as he was about to teach him a few more words, he saw his son watching eagerly from the sidelines. He was afraid that he would freeze his son after further delay, so he could only order in a stiff voice: "Go and carry a table."

Liang Jiugong suppressed his laughter, and recruited the little eunuch to carry him to the desk and put it in the center of the hall.

Dai Zi said "thank you", unfolded the two pieces of paper in his hand and placed them on the desk.

He pointed to one of the patterns and said to Yinfeng: "Your Highness once told me that the barrel of the gunpowder is the most important thing. Ordinary iron can't bear the momentum of gunpowder when it is shot. After discussing with the craftsman, I When smelting iron, the wrought iron is hammered more, and then the iron pipe is rolled up, but after many trials, the effect is still not good."

"How about it?" Yinfeng stared at the blueprint, "Could it be that the gun exploded, or it wasn't powerful enough?"

Although it was not obvious on the surface, he was actually very happy to chat with Dai Zi about the firecracker.He has a theoretical foundation in his hand, while Dai Zi has practical experience. This exchange between the two may spark new sparks.

Dai Zi thought for a while about the failures he created, and said seriously: "The two things His Highness said happened. I have tried many times, but they still can't reach the power described by the palace that day."

"How did you make the gun tube?" Yinfeng asked curiously.

"There is no fixed mold for this pipe, so I asked the craftsman to hammer out the cavity bit by bit."

Yin Reng nodded slightly. He had marked the specific size on the drawing. If Dai Zi followed suit, there would be no problem in making it.He has already learned about the craftsmanship of the firecracker in detail once again from the system, and knows that without the help of the so-called machine, manpower to create the cavity is the best way.

He rubbed his chin and thought for a while, then pointed to the drawing and asked Dai Zijiang, "Did you add charcoal or other ores when you smelted iron?"

"This is exactly what I want to ask Your Highness." Dai Zi was obviously excited, "I read the method of smelting pig iron or wrought iron into steel written by Your Highness, and asked the craftsmen to try it a few times according to this method. But The craftsmen have never used this method before, so they always have a hard time controlling the heat. Does Your Highness have a way?"

After listening to Yin Reng talking about the problem of the barrel, Dai Zi also thought that the inner rifling of the firecracker was also made of pig iron before, and it must be because of the material problem that caused the lack of power.

He hurriedly said: "The temperature is of great importance, and please Your Highness must find a way."

Yinfeng was also anxious, he changed his mind a bit, and said to himself: "We need to find an industrial thermometer to measure this."

He believes that craftsmen must have no problem building blast furnaces, but the temperature for quenching ore needs to be at least [-] degrees, and the control of the temperature is also very important.In the past, craftsmen could make a general judgment based on the color of the flame, but the blast furnace is sealed, so the color must not be visible.Therefore, certain auxiliary means of temperature measurement are necessary.

But where to find an industrial thermometer now?

Dai Zi heard this word for the first time, and asked with a puzzled look: "What did your Highness say?"

Yinfeng hurriedly changed the topic, "I'm going to figure out a way. You tell the craftsmen that the temperature of the blast furnace must be high enough when forging. It doesn't matter whether it's charcoal or coal, and everything that can support combustion is burned."

He thought for a while and then added, "There is also the packaging of the gunpowder used in the front box of this firecracker. Did you, sir, let the craftsmen knead it into pellets as Gu said? In addition, this firecracker needs to be filled with a kind of gunpowder. Ammunition made of lead, is that also made by artisans?"

Considering that it is impossible for craftsmen to forge the warheads of bullets by hand, Yinfeng chose the method of making miniature firecrackers and wrote it down. The requirement is that the production and filling of gunpowder are relatively simple.

"There is no problem with the gunpowder." Dai Zi hesitated for a while, and then said, "It's just that the craftsmen don't have the raw material for lead. We still need the emperor's decree to ask people to mine some."

"Lead mines exist in the Gansu area, so ask Fei Yang to mine them." Yinfeng said casually.

Fei Yanggu must be still arguing with Junggar at this time, and he is more patient than anyone else.Idle is also idle, so much labor is not in vain.

Dai Zi also thought so, and nodded in agreement.

He asked again: "Your Highness, the mold for making lead warheads drawn in your picture can only be made of the steel you mentioned?"

"Must," Yinfeng said solemnly, "Ordinary iron objects are easily deformed under pressure, and cannot be made to the specifications of this kind of ammunition."

Dai Zi also fell into a dilemma for a while. The craftsmen couldn't master the heat and the amount of charcoal, so they couldn't make steel.If you can't train steel, you can't make abrasive tools for making warheads.Then the progress of making a new type of firecracker has to be delayed again.

Kangxi listened to the lively discussion between the two, and he had long since given up on critiquing papers. He looked at the clock in Zhaoren Hall, and was about to remind the two of them that it was almost time, so we might as well talk about it tomorrow.

But I heard Dai Zi suddenly say: "Your Majesty, I would like to ask for an order. Please allow His Majesty to invite His Royal Highness to go to Jingshan with the minister tomorrow to see how the craftsmen make firecrackers, so that we can correct any inadequacies in time."

Kangxi: "..." I have tolerated you for a long time, don't push yourself too far!

Seeing that Khan Ama's face had turned livid, Yinreng hurried forward to smooth things over, "It's getting late today, sir, let's go out of the palace to rest first, and we'll talk about it tomorrow."

"Your Highness" Dai Zi still didn't want to give up, "The matter is very important, you..."

Yinreng was anxious, this elm head, if he continued, Khan Ama would really hit someone!

But he knew very well the honest and upright sons like Dai Zi, so he could only persuade him in a roundabout way: "Gu first find a way to get the temperature measurement in the palace, and ask Khan Ama to issue an order at the same time, so that General Fei Yanggu can do it." Some people go to dig some lead stones and transport them back to Beijing, and when everything is in order, how about I go to Jingshan with my husband?"

Dai Zi thought for a while, and nodded in agreement, "Forget it, what His Highness said is reasonable, so the minister will leave first."

Kangxi took a deep breath before saying in a deep voice, "You step back."

It wasn't until Dai Zi completely withdrew from the hall that Yinreng felt relieved. It was so dangerous, it almost made this Yumu's head screwed.

If he had agreed without asking Khan Ama just now, he might have made Khan Ama even more angry, then he really didn't know how long it would take to finish this book.

He was relaxed, but Kangxi raised his heart again.

He stared at Yinfeng unkindly, "Do you want to go to Jingshan?"

Yinfeng hurriedly apologized, "General Fei Yanggu ordered someone to transport the raw materials, and it will take at least half a month."

Don't get me wrong, Khan Ama, it's not what I thought, it was the elm head who asked for it just now.In addition, this matter is really important, and it is related to the future of our Qing Dynasty!

Kangxi waved at him feebly, "You step back."

Yinfeng wanted to say something more, but seeing that Khan Ama looked tired, he kept his mouth shut and did not argue.

After he left, Kangxi went to the desk that was put down, picked up the drawing that Dai Zi forgot to take away in a hurry, looked at it again and again, and suddenly sighed, "Queen, our son is so smart, is it good or not... "

The crown prince is the only son of him and the queen. From the time the child was born, he first wished for his son to grow up safely. When the child suffered a serious illness at the age of four, he only wished for his son to be healthy.After finally surviving the illness, the child was able to study, and he hoped that his son would be educated and understand the general principles so that he could inherit the great rule in the future.

Now that all his wishes have been fulfilled, he is a little bit reluctant.

It is a good thing for a son to be capable, and it is better than not being able to support the wall.But the son is too capable, which is even more worrying.

Kangxi recalled one by one what his son had done in the past few years. First, he was not afraid of infamy and encouraged him to change the system, and later he tried every means to persuade him to pay attention to business status.

All of these things were as he wished, but the child got worse and wanted to put himself in danger regardless of his status as the crown prince.

Kangxi couldn't help sighing, maybe it was because the night was too dark, the emperor felt a little lonely in his heart, that's why he had so many emotions.

However, after being overwhelmed with emotion, he still did not forget the business, and ordered Fei Yanggu to send people to mine the lead mine nearby, and send them back to the capital as soon as possible after mining.

Although it's just an ordinary imperial decree, it's so ordinary that it doesn't even need to be encrypted.Because even if they were intercepted by Junggar, they would not guess what the court wanted to do.After all, they had parted ways with the Russians.

But when Fei Yanggu received the order, he felt like crying.
