Liu Yuan said concisely and forcefully: "It's the material." ”

"Material?" Li Er said in surprise: "Liu Aiqing, what do you mean is that the iron used to build the fire gun is not good?" ”

"That's right, the strength and toughness of this iron are not enough, so this firearm must be scrapped after only a few times."

Tang Jin said with a depressed face: "Young master, this, this is already the best iron we can find, or the old craftsman of the Ministry of Industry provides a hundred wrought iron, I really can't find a better one, if this can't work, then the villain really has no choice." ”

Liu Yuan said with a straight face: "The better the thing, the higher the requirements, just like this firecracker, no matter how good the bamboo or wood, how can it not replace iron, if you want to make a better fire, there must be a breakthrough in the material, just like a wooden barrel, as long as there is a board is short, then this barrel will never be satisfied." ”

Everyone fell into deep thought all of a sudden, Liu Yuan's words were easy to understand, and they understood it as soon as they heard it, but it was easier said than done.

Eldest Sun Wuji nodded on the side and said, "It seems that the project of forging better iron needs to be put on the agenda earlier." ”

"The young master is right, I'm afraid that the right iron is not so easy to get." Tang Jin was also worried all of a sudden.

Firearms began to sprout in the Song Dynasty, and flourished in the Ming Dynasty, now because of the emergence of Liu Yuan, appeared in advance, theories and methods have, but the material can not keep up with the development, which has become a short board that restricts the development of firearms, Li Er's attention to gunpowder, beyond Liu Yuan's imagination, not only sent the imperial kitchen to improve their lives, but also transferred the best craftsmen to serve the research institute, in the case of a tight treasury, but also spent a huge amount of money to secretly build this underground secret room, it can be seen that its degree of attention, it is not an exaggeration to say, the fire in front of them. But it can be said that it is the crystallization of Datang's highest scientific and technological strength at this stage.

Liu Yuan recalled, and then said: "I heard that the most important thing in this iron smelting is the temperature, the higher the temperature, the cleaner the impurities in the iron can be removed, and now the main thing is that the temperature cannot be reached, recently I have thought of a way, maybe it can work"

After speaking, Liu Yuan said some of the methods he knew about the Tao, which were the simplest and most practical. It is blast furnace ironmaking, this method has been used in a national steelmaking movement in China, and the technical content is not high, even a township has conditions, and it is not an advanced thing. But I don't know how many times more advanced than the techniques of the Tang Dynasty, and it is just right to use it. However, Liu Yuan has only one theory and direction. I also remembered some simple points, but I didn't have practical experience in how to do it, so I had to go out one by one and let them explore it.

Don Kim is like a studious schoolboy, listening with his ears pricked up. For fear of missing a word, sometimes I use notes to make it seem very serious.

"Alright, that's all. Let's explore slowly, three feet of ice, not a day's cold, the towering Great Wall, not a day's work, don't be afraid of failure, if you don't work once, ten times, you will do it a hundred times, there will always be a day of success. Liu Yuan comforted Tang Jindao on the side.

Everyone has their own hobbies, like Liu Yuan when he is bored, he likes to make a few pieces of jewelry to relieve boredom, use dozens of different carving knives to display his talent between square inches, for a satisfactory work, sometimes a sitting is a whole day and is also happy, and Tang Jin likes to refine things, most like to create something that was not originally there, Liu Yuan is unwilling to do the work, for him, it is as energetic as refining immortal medicine, after listening to Liu Yuan's theory, Tang Jin immediately has an urge to try.

Tang Jin said excitedly: "Yes, young master, the little one must work hard, and he must make a better firecracker." ”

Li Er nodded secretly, thinking that it was right to call Liu Yuan, he and the eldest grandson Wuji were extremely satisfied when they saw it, but they didn't expect Liu Yuan to point it out sharply, and put forward so many suggestions, it was really the Tang Dynasty Fuxing Lucky General.

"Liu Yuan, you kid, if you have any suggestions, don't say a little and leave a little, you said it earlier, maybe this fire gun won't be like this today." Li Er said unceremoniously.

The eldest grandson Wuji on the side looked at Li Er, and glanced at Liu Yuan meaningfully, smiled slightly, and did not speak, and Tang Jin on the side looked at Liu Yuan differently: Being scolded by the emperor as a kid, how good the relationship is, saying that it is scolding, being close is close, it can be seen from here that the emperor loves and attaches importance to the young master.

Of course, if a person has talent and can do things, but he has no ambition, it is difficult to dislike it.

Liu Yuan thought for a while, and soon had an idea: "Actually, we have made a fire system, and we can also use gunpowder to make other weapons, such as shells, that is, to wrap gunpowder in iron or stone, make the fuse a little longer, and use a trebuchet to throw it at the enemy's position, the lethality is huge, by the way, it can also be made into a big ball, it is the most suitable to stay in a high place, it is placed flat, when the enemy attacks, ignite the fuse and kick it down, roll into the enemy bush and blast, it is smashed and exploded, and the power is absolutely strong, It can also be made into a rocket or tie several or dozens of rods together, and put them together, and the scene will definitely be shocking. ”

"Okay, good, it's a whimsy, write it down, write it all down." Li Er is a great expert in warfare, Liu Yuanyi said, he immediately realized its benefits, and hurriedly commanded when he heard the words.

"Yes, Your Majesty, the little one is remembering." Tang Jin on the side put down his pen like a fly, and hurriedly wrote down all Liu Yuan's words

When Liu Yuan left, he realized that he had been tossing in the underground secret room for nearly two hours unconsciously.

"Your Majesty, be careful, the road here is slippery." When he came out, the eldest grandson Wuji reminded Li Er to pay attention to the steps under his feet.

"Uncle Guo also needs to be careful, these are all trivial." Li Er said, waved away a guard who wanted to step forward to support him, and said lightly: "I don't need someone to help me yet." ”

"Yes, Your Majesty"

As soon as Liu Yuan came out of the secret room, he was used to the light in the basement, but now when he came out, he felt that the light was a little dazzling, so he quickly closed his eyes and got used to it after a while.

"Well, it's worth the trip." Li Er was obviously very satisfied with the gains of this trip, and he had mastered one more secret weapon, so that Datang had one more hole card, and when he saw the fire gun, his face had been smiling, and he couldn't hide his excitement.

The eldest grandson Wuji also said happily: "The emperor is ambitious, and he is widely virtuous, that is, God bless the Tang Dynasty, the emperor, the Tang Dynasty is under the emperor's rule." I will definitely be able to create a foundation that I have shown before. ”

"Haha" Li Er couldn't help laughing, and said to the eldest grandson Wuji after laughing, "The prosperity of the Tang Dynasty also requires the help of virtuous ministers like Uncle Guo." ”

"The old minister was originally the emperor who went to the soup to fight the fire." The eldest grandson Wuji said with a straight face.

Liu Yuan was on the side, goosebumps were up, these two old boys actually praised each other so sourly, everyone loves to listen to good words, even if they are virtuous and capable ministers, they can't be reluctant to be vulgar in life, they usually see the eldest grandson Wuji is unfathomable, but I didn't expect that there would be fewer people. Just slapped Li Er's sycophant, although the shooting was not very clever, but the time was very good, and his identity was also special, looking at Li Er's face. You know that you have hit the point.

Well, this is the Tang Dynasty. It is expensive to be the son of heaven Li Er. Sometimes in order to achieve their own goals, they have to endure their temper and suffer a little dark loss, the last confrontation between the imperial power and the scholar clan ended with Li Er taking the initiative to show goodwill.

Just when Liu Yuan was thinking wildly, Li Er suddenly asked, "Liu Yuan." ”

"Weichen is here" Liu Yuanleng paused for a moment and immediately responded.

"Your Moyun printing factory still has Chang'an Daily. Find a suitable time to move out, this place is no longer suitable. ”

Li Er is ready to make a big move, and he wants to classify this place as a secret workshop, and Chang'an Bao and Mo Yun are here. It's really inappropriate, especially Chang'an Daily, when it was issued, there was an endless stream of people who came to get the newspaper, and it was inevitable that there would be mixed people, who had no results before, so they let it go, Liu Yuan was also greedy to touch the light of those guards, don't worry about someone making trouble, now that the fire gun is out, Li Er has already gracefully transferred the eviction order.

Liu Yuan said with some hesitation: "Where did the emperor say to move?" ”

"You kid, I'm afraid that if I don't have you, I will say it directly" Li Er said angrily: "Moving to Wubenfang, whether it is Chang'an Daily or Moyun, it is all with the fragrance of ink, which is consistent with Guozijian, I will arrange a good place for you, it will not be worse than your place." ”

"Yes, Emperor Xie, Weichen will move out as soon as possible." Liu Da was overjoyed and hurriedly responded.

In terms of geographical location, Wubenfang is a prime location, more than ten times better than Xiangrenfang, and Li Di is obviously a reward component, Liu Yuan is very satisfied with this.

Li Er waved his hand and said, "Okay, that's it for today, I want to go back to the palace to correct the folds." ”

"Congratulations to the emperor."

"Congratulations to the Emperor"

Liu Yuan and eldest grandson Wuji hurriedly sent Li Er away, and after Li Er left, eldest grandson Wuji chatted with Liu Yuan for a few words, and also left by car.

Both of them left, leaving only Liu Yuan, the fat man Tang Jin, listened to Liu Yuan's words and immediately devoted himself to research, and now only Liu Yuan is standing alone in the research institute.

"Goo" belly suddenly screamed, Liu Yuan then remembered that he came out without much breakfast, and tossed for more than two hours, those snacks were not hungry, and now it can be said that he was so hungry that his stomach was sticking to his back, Liu Yuan couldn't help but slander: This Li Er, saying that he has to deal with official business, he has been tired here for most of the day, and he didn't even invite him to eat, it's really picky.

Liu Yuan didn't wait anymore, and went straight into the carriage after going out.

"Young Master, where are you going now?"

Liu Yuan waved his hand: "Go back to the house for dinner." ”

"Okay, young master, sit tight." The coachman shouted, flicked his whip, and went straight home.

Eat, eat, get out of the carriage, Liu Yuan walked to the house, people are iron, rice is steel, if you don't eat a meal, you are hungry and panicked, Li Er slammed the door, he didn't treat himself badly, by the way, he slaughtered a sheep in the morning and got half a fragrant roe deer, Xiao Niang must keep it for herself, when she thought of eating, Liu's saliva flowed, and she couldn't help but speed up her pace and go inside, but she didn't expect to bump into a person at a corner.

"Ouch" Liu Yuan couldn't help but want to scold, but he didn't expect that as soon as the collider saw him, he immediately said excitedly: "Young Master"

"Why are you in such a hurry? Be careful when walking. As soon as he saw that it was the housekeeper Liu Quan, Liu Yuan couldn't help but reprimand.

"Young Master" Liu Quan didn't care about explaining, and hurriedly said: "The villain is trying to find you, hurry, hurry, Mrs. is about to give birth." (To be continued......)

PS: I miscalculated the time, and almost turned the child in Mengyao's belly into Nezha, I went back and revised it, and I had to straighten out my thinking, it's late today, I'm sorry.
