Great Tang Southern Emperor

"I'm also trying to figure out a way to smelt steel with higher hardness." The only way now is to smelt harder steel and then make sharp knives, so the yield rate should be much higher.However, the cannon steel was already bestowed by the god of luck, and Li Zhen herself felt that it was unrealistic to refine even harder steel by luck.

So during this period of time, Li Zhen regretted why she had to study mechanical design in her last life. If she had known that she would travel to the Tang Dynasty, it would be great to study metal materials and heat treatment, even if it was a minor, it would not be as good as it is now. In this way, there are obviously many ideas in the mind, but they are limited by the materials and cannot be implemented.

Chapter 48 Use black iron to make knives?too extravagant

Fang Yiai rested her chin, and thoughtfully said: "Actually, if you want to increase the hardness, there is no way out."

"Oh?" Li Zhen and Du He immediately turned their attention to him, and Li Zhen was even more excited: "Really? If you can really help me solve this problem, I will reward you a lot. Didn't you always want a A heavier knife? I will ask my craftsmen to help you make the best knife in the world, and I will give you a majestic armor."

"Really?" Fang Yi'ai's eyes also lit up. He always felt that the current Mo Dao was too light and couldn't fully exert his strength. He always wanted a heavier one.But although he is also a well-known young master in Chang'an City, he is not enough to affect the Shaojian Mansion, and the price of a Mo knife is astonishing, even Fang Xuanling's net worth will feel distressed, let alone Fang Yi. love it.

So after hearing that Li Zhen had a Thousand Hammer Workshop that was no less powerful than the Young Supervisor's Mansion, he always wanted Li Zhen to make him a good knife, but because he had no merit, he was embarrassed to ask Li Zhen.Moreover, Qianhammer Workshop is far away in Chang'an, and when he finished his outfit before sending it over, it is estimated that the war is over.

"Of course it's true. The premise is that you can help me solve the problem of steel hardness." Li Zhen said without hesitation. In fact, he had already built a batch of high-quality equipment, but he didn't show it. Now he just took this opportunity to dazzle Someone's eyes.

"Very good, I hope Your Highness can do what you say." Fang Yiai said with a smirk: "My method will definitely work, but I don't know if you are willing to part with it, Your Highness."

Du He became impatient, pushed Fang Yiai, and reprimanded: "Why so much nonsense? Are you going to say it or not?"

"It's very simple. Since ordinary steel is not hard enough, let's use special iron."

"Aren't you talking nonsense? What kind of iron in the world is as hard as this thing? Which kind of steel is more special than this gun steel?" Du He slapped every word, and the gun barrel was bang bang rattle.

Li Zhen also disdainfully said: "That's right, what was my idea when I thought you were, it turned out to be such a bad idea, don't want your precious sword anymore."

"Who said there isn't one?" Upon hearing that the treasured sword was gone, Fang Yiai became anxious and argued, "Have you forgotten the Tianwai Xuantie?"

"Tianwai Xuantie?" Li Zhen was taken aback.

Du He was even more angry: "You are talking nonsense. The Tianwai Xuantie is indeed harder than the gun steel. The question is, can we make it?"

"That's why I said that Your Highness is reluctant." Fang Yiai laughed and said, "Anyway, I have already made up my mind, so it's up to you whether I need it or not. Your Highness, you can't refuse."

"Are you still talking about you?" Du He was so angry that he pointed at Fang Yiai and wanted to scold him, but Li Zhen stopped him: "Wait a minute, what he said makes sense."

"Ah? Does that make sense?" Du He quickly put his hand on Li Zhen's forehead: "It doesn't burn either."

"Go, go, you're just burning out your brain." Li Zhen patted Du He's hand away, and said, "What he really said made sense, why didn't I think of it? Brother Yiai, don't worry, you Your hint has solved my big trouble, and I will not let your reward go away."

Mysterious iron, that is, meteorite, has a very strong material performance because it has gone through the vacuum of outer space, weightlessness, various radiations, and high-temperature smelting when it landed.In ancient times, black iron was generally used by swordsmiths as the material for making swords. As long as a little black iron was added to ordinary soldier iron, it could immediately become a magical weapon that cuts iron like mud. properties of iron.If black iron is really used to make knives, there is no doubt that it will be possible. Even if black iron is hard to come by and the price is astonishing, it is no wonder that Fang Yiai would ask Li Zhen to give up.

Du He struggled and said: "But using black iron as a knife, isn't it a bit too wasteful? Wouldn't it be better to use it to make a sword?"

Li Zhen said helplessly: "This is also the only way out. If there is another way, why would I be willing to use black iron? Besides, you think the cannon made by a hundred black iron knives is powerful, and it is better to hold it with one hand. How good is the master of the sword?"

Du He said without hesitation: "Of course the cannons are powerful. No matter how hard an expert kills, he can't kill 1000 people, right? But a single bombardment by a hundred cannons can cause hundreds of deaths.

But Your Highness, where did we get the black iron?Black iron is formed by falling stars from the sky, even if you have money, you can't buy it. "

"This can't but be said to be God's will." Li Zhen smiled confidently: "Coincidentally, I once got a black iron meteorite, but it was as big as a fist, and it weighed about twenty catties. Yes I bought it in a blacksmith's shop, it is the treasure of the town store, and it took me a lot of effort to get it."

Du He also clapped his hands and said with a smile: "No wonder your Highness said it was a coincidence. It's too coincidental. You can do whatever you want. But I still feel it's a pity."

"It's nothing to regret." Li Zhen said: "That piece of ore can produce at least a dozen catties of black iron (the quality of meteorite is that the content exceeds 80), so how much black iron can be made into a knife edge, how much do you think can be produced?

Moreover, black iron is very wear-resistant and has high hardness, so it won't be consumed too quickly, at least one or two years is enough.What's more, even if these dark irons are scrapped, we can recycle them and recast them, so that the support time will be longer.

For such a long time, if the craftsmen can't research harder steel, then what's the use of them? "

"That's right." Du He nodded: "Anyway, it's not impossible to recycle the black iron. At worst, after the new steel is smelted, we can re-smel the black iron and recast it into a magic weapon."

"Dizzy, why are you still thinking about this?" Li Zhen was also speechless, why didn't she find out that Du He has the attribute of a money fan before?

"Your Highness, don't try to change the subject. Where's the treasured sword?" Fang Yiai couldn't help but reminded Li Zhen and Du He as they talked more and more happily.

"Okay, okay, stop yelling, can I get rid of your treasured sword?" Li Zhen said impatiently: "Well, aren't you in a hurry to get the treasured sword? Then do me a favor and go to the logistics battalion to general Pull over Xuanzi No. [-] car, and I'll give you a knife when the car comes over."

"Yes, this subordinate will do it now." Fang Yiai heard that there was a knife, and hurriedly got on the horse and galloped towards the camp.

Not long after Fang Yiai left, Li Jing and the others rushed towards Li Zhen.

"My God, Your Highness, this cannon is really powerful." Yuchi Jingde jumped off the horse without waiting for the horse to stop, and yelled: "Your Highness, you didn't see that, after the cannon exploded, There is not a single standing thing within a radius of three feet, whether it is a big tree or a small tree, or even a layer of turf has been peeled off, if it falls into the crowd, it will be turned on its back and blood will fly all over the place?"

"Yes, Lord Changshi, this cannon is so powerful, can we also send some people to learn from you?" Su Dingfang next to him also asked.

"It's definitely not a problem to learn, but I only brought one cannon this time, and the shells on hand are only three hundred. Besides, these sixty people are already my limit. If there are more, I will not be able to teach them." So if you really want to learn, you can only wait for the next batch. By then, the artillerymen I trained have already left the army, and the number of cannons has also increased to a certain extent. Let’s talk about this problem.” Li Zhen said her own problem, He did not lie. Three hundred cannonballs were evenly distributed to sixty people, and each person had five rounds of training. If there are more people, this teaching will not go on at all.

Chapter 49 God's Edge

What's more, Li Zhen has said more than once that this is only the first cannon, which is purely experimental. Although the cannon steel is qualified, no one knows what the lifespan is. Maybe it will be scrapped if it can't even finish the 500 cannons. (The life of a general cannon is 1000~[-] rounds, no matter how good the performance of Thor One is, it will not exceed this range).

Seeing that the faces of the two people looked a little ugly, Li Zhen quickly added: "Although they can't let them get started, they can still watch from the sidelines, and they can also come to my place at night and take theoretical courses with me first."

"Thank you Master Changshi for that." The two people looked a little better.

After the two of them had finished speaking, Li Jing asked, "Master Changshi, what is the output of this cannon?"

"Production is not a problem. The only problem that restricts production has been temporarily solved by Fang Yiai. As long as there are enough people, at least one school a day is still an unwritten problem." Because she didn't calculate it carefully, Li Zhen just said a conservative figure.In fact, if the production capacity can really be maximized, let alone one, even ten should not be a problem-you must know that even in the late Qing Dynasty, the production capacity of the Sichuan Arsenal was less than one hundred cannons a month.

Of course, Thor No. [-] is far less sophisticated and less complicated than the cannons of the late Qing Dynasty, and there is basically no comparison.

"Fang Yiai? Can he still have this ability?" Yuchi Jingde curled his lips, thinking that Li Zhen must be crediting his subordinates.

"If you don't believe me, you can ask Du He." Seeing Yuchi Jingde's expression, Li Zhen knew what he was thinking.

"That's right, it was Fang Jun who proposed to make it with meteorite iron."

"What did you say? Meteorite?" Even Li Jing was not calm this time, and asked Du He, "Be clear, where did he get the meteorite? What is he planning to use the meteorite for?"

Not only him, but everyone who knew about Meteorite was breathing heavily, their complexions were rosy, and their eyeballs were starting to become bloodshot—Li Zhen knew that she still underestimated the attraction of Meteorite to warriors.

"Chairman, don't be nervous, don't be nervous, I provided the meteorite, and I'm going to use it to make knives." Seeing that the situation was not good, Li Zhen was afraid that Du He would tell the truth, so she hurriedly explained, but couldn't help but say goodbye Du He winked: "It's a sharp-cut knife, don't you think so, Du He?"

"That's right, that's right, it's a sharp-cutting knife, and we didn't use it indiscriminately." Du He was not an idiot either, after seeing Li Zhen's wink, he nodded hastily.But Li Zhen wanted to beat him up, what the hell are you doing with the last sentence?Not only did this not increase his persuasive power, but on the contrary it played a superfluous role, which might arouse the suspicion of Li Jing, an old fox.

If not, Li Jing immediately grasped Du He's words: "Use it indiscriminately? What do you mean? What are you going to use the meteorite for?"

"Well, this is like this." At this time, Du He wanted to give himself two ears, what's the point of saying that?It's just that the words have been listened to by Li Jing and the others, and changing the words at this time will arouse suspicion from others, so they can only look at Li Zhen for help.

"It's not about using it indiscriminately, but about making good use of it. Chief Manager, you misheard, hehe." Li Zhen smirked: "We are discussing how to make reasonable use of that piece of meteorite to create more magical weapons."

"Really? Why doesn't it sound like me?" Li Jing said slowly, then turned around and asked, "Is what you heard about misuse or good use?"

"Use indiscriminately." Everyone roared in unison, not giving Li Zhen any face.
