After the fall, Shangshu of the Ministry of Industry no longer dared to think about anything, and respectfully took Yinzhi to the treasury of the Ministry of Industry. After opening the storeroom, he asked the servant to hurriedly open all the windows inside to allow air to circulate, so that Prince Cheng and the others could see the firearms placed in the storehouse of the Ministry of Works......

It can be seen how much the Qing Dynasty did not attach importance to firearms...... Some firearms have a finger's thick amount of dust on them. Kangxi didn't know, but Yinzhi was clear. Historically, the Qing Dynasty would soon have a war with Geldan in the north......

If the Qing army had powerful firearms at their disposal, why couldn't they extinguish a small Geldan for a long time?

But it's different now, and it's still too late to start researching from now on. Even if more advanced firearms are not developed, more existing firearms can be made to slag!

Yinzhi looked at the pile of firearms in front of him that were like "scrap copper and rotten iron" in the eyes of the Ministry of Industry, and his eyes were very hot. He arched his hand at Dai Zi and Nan Huairen and said, "This king is young, and he has only read some books on this matter, and he has some ideas, I don't know if the two of you are willing to listen to one or two." ”

Prince Cheng was able to put down his body and talk to the two like this was something that the two of them didn't expect, since Dai Zi and Nan Huairen had some research in this area, the two of them were naturally willing to listen.

It's just that this warehouse is really not a place to speak, and the Ministry of Industry Shangshu hurriedly invited the three of them to the empty room on the side. Yinzhi also sat down on the main seat unceremoniously, otherwise the remaining three people would not sit down at all. "The two of you also sit, and there is Lao Du Shangshu to take the firearm drawings he saw earlier to the king and the two adults to take a closer look."

Du Shangshu hurriedly said that he didn't dare to go out of the house, and trotted all the way to send the drawings of the bottom of the old pressing box that he hastily prepared yesterday to Prince Cheng.

As an old fritter who has been in officialdom for many years, the Ministry of Industry can be regarded as seeing it. Where is Prince Cheng a bear child, he is clearly a smiling tiger. Looking at the young age, my heart is like a mirror. It's not surprising to say, after all, Prince Cheng has been personally raised by the emperor for many years, where can he compare with ordinary children......

Before he saw the drawings, Yinzhi had been drinking tea and looking at the boots on his feet, thinking that this ancient weaver was really skillful, even this plain black satin could weave dark flowers...... I just don't know how much silver taels the Ministry of Internal Affairs will quote for such a pair of forging boots.

He remembered that when Daoguang was in the later years of the Qing Dynasty, the emperor was thrifty, and the dragon robe was torn and patched and continued to be worn. But I don't know if Daoguang would choose to patch the dragon robe after he knew that it would cost thousands of taels of silver to patch his dragon robe......

A few days ago, Kangxi actually asked himself to think about how to govern the Internal Affairs Office, which shows that Kangxi has noticed that the Internal Affairs Office is secretly tired...... Even if the salt affairs in Jiangnan are put aside for the time being, the moths of the Internal Affairs Office must be cleaned up.

Looks like someone is going to be unlucky. I just don't know how Kangxi will rectify it, and the rectification is not thorough......

In Yinzhi's eyes, the danger of the idle Eight Banners heirs in Beijing in the future is far greater than the danger brought by the moths of the Internal Affairs Office. It's just that he didn't know how to arouse Kangxi's attention in this matter, so he opened a restaurant to Kangxi just to test the outside world.

However, everyone regarded this incident as the emperor's favor for Prince Cheng, and asked the Internal Affairs Office to find a restaurant for Prince Cheng to play.

"Prince Cheng, the drawings have been brought to ......" The drawings were all prepared, and the Ministry of Industry Shangshu immediately took the drawings as quickly as possible. There is Lao Du Shangshu ...... "Drawings involve such a thing as confidentiality, except for the Ministry of Industry Shangshu personally ran errands, and no one else was at ease."

Seeing that the Ministry of Engineering Shangshu had no intention of going out after taking the drawings, Yinzhi didn't pick up anyone. Everyone gathers firewood and the flame is high, and those who can do it must have two brushes in their hands, and maybe they can also say some useful opinions.

"Let's take a look, this is the blueprint of my firearm. Master Dai has participated in the pacification of the three feudatories, and has also seen the power of our Qing artillery. This king wants to rebuild this cannon, and wants to reduce the weight and volume of this cannon, and increase the range and power again. You can all tell me how to make the most appropriate transformation. Yinzhi said while holding the drawings in his hand.

Tong guò saw the real thing, and then looked at the drawings in his hand. The size of this gun is too large, and the weight must not be light. If these two aspects are improved, the convenience of the battle will be greatly improved, and the movement that the soldiers can carry will naturally be greatly improved......

Nan Huairen thought for a while, "I just took a look at the artillery of the Qing Dynasty, the barrel is a little too thick, if you want to be thinner, you need refined copper......" Nan Huairen's implication is that the amount of refined copper smelting in the Qing Dynasty is insufficient, and it is not easy to reduce the weight of the artillery.

Dai Zi also agrees with Nan Huairen's point of view. At this time, Shangshu of the Ministry of Industry, who had been listening from the sidelines, spoke, "The Ministry of Refined Copper can be smelted, but it takes a lot of time and the output is not high......"

"It's good to be able to produce it, and try to smelt as much refined copper as possible without delaying the operation of the Ministry of Industry. When the success is completed, the king will ask Khan Ama for a great merit to the Ministry of Works. Yinzhi felt that in his impression, it was good that the Qing Dynasty could smelt refined copper, even if it took more time.

Yinzhi's big cake has been thrown, and it is the emperor's intention to improve the artillery...... How can the Ministry of Industry have a reason to contradict it.

"Does the Ministry of Industry have smelted refined copper now?" Yinzhi asked, the Ministry of Industry can refine refined copper, and it is not too early. He suddenly thought that if the refined copper of the Ministry of Industry could not reach the required level, wouldn't it be empty joy?

In the final analysis, he had no confidence in the smelting technology of the Qing Dynasty. There is no record in the history books about the smelting level of the Qing Dynasty, so it is no wonder that he Yinzhi is really relieved.

"Yes, yes. Wechen will go and get it. Du Shangshu said that he was about to get up to get it, but was stopped by Yinzhi, "This kind of thing doesn't need to bother Lord Shangshu to go in person, just ask the slave to get it." The Ministry of Industry Shangshu nodded, and asked the little officials on the side to quickly bring the refined copper materials made by the Ministry of Industry to Prince Cheng and the two adults.

Although Nan Huairen and Dai Zi's official positions are not high, even if they succeed in this matter and are promoted, they can't surpass him, the secretary of the Ministry of Industry, but being valued by Prince Cheng is basically the meaning of the emperor's attention.

Thirty years in the east of the river, thirty years in the west of the river. Who knows what will happen in the future, in short, it's good to leave yourself a way back......

The little official came back running, and Du Shangshu waved his hand when he saw that he was out of breath and called down to rest. Yinzhi raised his chin and Xiaoshunzi understood what Yinzhi meant. walked out and rewarded the errand boy with two coins of silver barley, "Good life take it, the prince will reward you for running errands." ”

Inside the house, Yinzhi knocked on the copper ingots placed on the tray. Seriously, he couldn't tell if the big red bump was good or bad, but it didn't look like it was bad...... Yinzhi only remembers ordinary copper based on the life experience of his previous life, which seems to be yellow.

As for the condition of this piece, it all depends on the meaning of Dai Zi and Nan Huairen......

"Prince Yucheng, this copper is very pure, and it is really a waste to use it to make cannons......" Dai Zi said, and Nan Huairen also nodded on the side to agree with Dai Zi's idea.

It is indeed a bit unrealistic to use pure copper to make cannons, and it is better to retreat to the next best thing. "If you mix other metals in pure copper, such as steel, will it be stronger?" Yinzhi thought for a while and said. For a while, Dai Zi and Nan Huairen couldn't tell this question. "This Weichen does not dare to make a conclusion, the hardness of the alloy is indeed higher than that of pure gold, but what proportion of the hardness of the alloy is the highest still needs practice to get the final result."

Yinzhi nodded, it was a little early, and he couldn't live in the Ministry of Industry and wait to see the results. But if you go back to the palace at this time, it's still a little too early, just get in before the palace gate drops the key. His homework is a big deal, and he needs to be greedy for some darkness......

Anyway, they all have to fight at night, so Yinzhi took advantage of being outside the palace to sit in the restaurant he opened.

Looking at the beautiful decoration of Longyuan Building, Yinzhi is still very satisfied. Listen to a storytelling and nibble on a roast duck. This busy little day couldn't be more pleasant.

As soon as Yinzhi sat down, an errand boy came over and asked Yinzhi what he wanted to eat. Judging by the way he was dressed, it should be that the little young master of the big family secretly ran out to play, and he was hungry and took the servant into this Longyuan Building. "What does this young master want?" The little guy asked guessingly.

"A roast duck." Yinzhi replied dryly. Xiao Shunzi persuaded on the side, "Third Master, you still have to eat at night." Don't eat so much......" Yinzhi pointed to the stool on the side, "Sit, I naturally can't eat alone." You also eat some ......" Xiao Shunzi fart/stock only took one side, and when he heard Yinzhi's words, he immediately stood up and wanted to kneel down for Yinzhi, and suddenly thought that this was a restaurant, not a palace. Revealing the identity of the master may bring danger to the master. He bent down and said. "Slaves don't dare to ......"

"If you are told to eat, you will eat, what you have been with your master for so many years. How can you ...... if you're afraid of poison?" Yinzhi muttered. The shopkeeper not far away noticed Yinzhi and Xiaoshunzi as soon as he came in. personally brought the sliced roast duck up to serve Yinzhi, but asked Yinzhi to stop it. "Master has a long hand, I don't need you to serve. Do your best, lest you attract the attention of others. ”

"Yes, yes. The little one got it. The shopkeeper smiled so much that the folds on his face were piled up, and he didn't get Yinzhi's eyelids to raise so much. It's not that Yinzhi has no one in his eyes, but this roast duck is really fragrant, and Yinzhi just wants to swallow this roast duck into his stomach at the moment.

Yinzhi unceremoniously took the roast duck meat rolled in lotus leaf cake handed by Xiaoshunzi and stuffed it into his mouth, and opened his eyes after tasting it carefully. "Xiao Shunzi, you can eat it too. Ye can't eat so much by himself. Besides, isn't it just rolled up, the master will roll it himself, ......" Yinzhi snatched the lotus leaf cake in Xiao Shunzi's hand, rolled one for himself and stuffed it into his mouth, pointed to the roast duck and told Xiao Shunzi to eat it too.

When Yinzhi was munching on the roast duck, he felt a strange gaze focused on him, not the two secret guards...... Yinzhi looked back at the strange gaze when he drank the duck soup, and it turned out to be a middle-aged man and a child.

Although Yinzhi thinks that it is a child, he is three or four years older than Yinzhi now. was holding a roast chicken and eating it all over his face, but his father next to him had a helpless look...... Presumably because he is so polite, and then he sees his son worried.

He should have called his Khan Ama to come and see what it means to have people outside the world, and there is a sky outside the sky. The cumbersome rules in the palace Yinzhi really remembered that his brain was about to explode, and he would rather memorize two paragraphs. But Yinzhi finally learned the rules perfectly, but it depends on his mind whether he follows the rules or not.

Xue Pan honestly followed Xue Qian this morning to learn the account book all morning, and in the afternoon, he pestered his father to say that he would follow his father out for a walk. Xue Qian saw that Xue Pan had studied quite seriously in the morning, so he agreed, anyway, he was watching by his side. He wrote the fold and handed it to the secret guard to present to the emperor, just in time to go out and relax in the capital.

The father and son walked to Longyuan Tower. As soon as Xue Pan smelled the fragrance wafting from the Longyuan Building, he couldn't walk, so he dragged his father into the Longyuan Building.

Xue Qian saw that there was not much business in this Longyuan Building, so he also followed Xue Pan in. Not long after entering, he noticed a small person walking in, followed by a young man with a white face and beard. Seeing that the little man's clothes were extraordinary, he concluded that Yinzhi was either rich or expensive, and then saw that the boots on Yinzhi's feet were satin cloth from his own tribute, and the alarm bell sounded in his heart.

Then he glanced at the young man who was sitting on the side but more uncomfortable than standing, his face was white and his voice was a little shrill ...... Xue Qian guessed that this person was a eunuch in the palace. turned to take a closer look at the belt tied around Yinzhi's waist embroidered with gold thread, and the jade pendant on his waist guessed the identity of Yinzhi's prince.

Then it is not difficult to guess that the prince of this Longyuan Building is Yinzhi himself. Seeing Prince Cheng looking in his direction, Xue Qian hurriedly took his gaze back and put it on his eldest son.

looked at the four-year-old Prince Makoto and then looked at his eight-year-old eldest son......

Why is it so much worse?

Yinzhi only ate a small half of the roast duck, and then stopped eating it after burping lightly, lest he go to the palace to eat another meal and not digest it, and he will feel uncomfortable at night. "Little Shunzi, wrap up the rest. In addition, pack five roast ducks and bring them back to the palace...... Then pack three of them and send them to Jia Lian and their family......"
