This is the first time that such a major accident has occurred since the old blacksmith shop in Guangludao made bird guns, and Li Yuanqing did not dare to slack off, so he immediately rushed to the blacksmith shop. Pen, fun, pavilion www. biquge。 info

The order of the blacksmith shop is quite normal, and there is no panicked appearance as Li Yuanqing imagined, which makes Li Yuanqing's heart settle down a little.

Xu Liang got the news and hurriedly came over to meet Li Yuanqing.

His hand was a little injured and bandaged, but he was in good spirits, and he respectfully kowtowed to Li Yuanqing, "Xu Liang has seen an adult." ”

Li Yuanqing nodded and said with concern: "Brother Xu is okay, right?" ”

Seeing that Li Yuanqing didn't ask about the accident directly, but asked about his body first, Xu Liang's heart couldn't help but warm, "My lord, fortunately, it is the blessing of the Bodhisattva, the little one just scratches some skin on his hands, and there is no big problem." ”

Li Yuanqing nodded, "It's okay if people are fine." Wasn't it all going well before? How could such a thing happen? Have you found the reason? ”

Xu Liang shook his head and said with annoyance: "My lord, the process of making the bird gun is completely in accordance with the process. Old Man Yang and I also checked carefully and didn't find anything abnormal. The small ones don't know why there was a sudden change in the process of test firing. It seems that the gun pipe is not made of iron, but rather ice, and a little fire door, the villain feels wrong, but it is still too late. ”

Li Yuanqing nodded, "Where is the bird that had an accident?" Bring it over. ”

Saying that, Li Yuanqing said to Xu Liang and Old Man Yang again: "Have the other bird guns been test-fired?" Questions? ”

Old Man Yang hurriedly said: "After Xu Liang's accident, the rest did not test fire. ”

"Hmm." Li Yuanqing pondered for a moment, "Now let's test those too." Be careful. ”

"Yes." Everyone didn't dare to slack off, and hurriedly took out these dozens of bird guns and test-fired them in turn.

What is shocking is that there are more than 30 bird guns, and there are more than 10 guns, all of which have been blown up, but some are heavy and some are light, but most of them cannot be used.

Fortunately, everyone was prepared in advance and there were no casualties.

"W-what the hell is going on?" Xu Liang looked at the remains of more than a dozen bird guns on the ground, and the pain was indescribable.

Old Man Yang was also full of solemnity, but he couldn't do it.

Li Yuanqing behaved very easily.

At this time, even if Li Yuanqing doesn't understand the bird gun technique, he is the backbone of everyone, once he shows a furious look, the people below are shocked and frightened, I am afraid it will be even more difficult to find the way.

Li Yuanqing squatted down and carefully examined the remains of several bird guns, the inner walls of their guns were very smooth, and it could be seen that Xu Liang and them should have been carefully polished.

The thickness of the gun tube is about 0.5 centimeters, and it stands to reason that this thickness, the impact of gunpowder, is not able to explode.

What the hell is going on?

After a closer inspection, I still don't have a clue.

Li Yuanqing stood up and said to the two: "Is there something wrong with the process this time?" The bird gun that was made before didn't have such a thing, right? ”

Old man Yang said: "My lord, it shouldn't be." Here in our blacksmith shop, the process of making bird guns is now followed, especially the gun pipes, and there will be no mistakes. According to Xiao Lao'er, this time, it seems that our iron material is not good. ”

"Oh?"

Li Yuanqing took a look at the remains of these birds, and found that even if they were shattered, the surface was black and shiny, and they were finely polished, and this healthy metallic luster should not be a problem with the iron.

"I don't think there's anything wrong with the iron. Could it be something else? Like heat or something? Not well controlled? Li Yuanqing tried his best to restrain his tone, tried to maintain peace, and said to Old Man Yang.

Old Man Yang nodded, but shook his head again, "My lord, I can't say it well." However, in the process of making iron, I felt that something was wrong, but I can't say what was wrong. ”

At this time, Xu Liang squatted in front of the remains of these birds, carefully inspecting them.

When this happened, the blacksmith shop could no longer continue to produce, and all the craftsmen and workers came out and watched from a distance, not daring to speak.

Li Yuanqing glanced around, and was faintly anxious.

His foundation was finally on the right track, but he encountered such a tricky thing.

The key is that Li Yuanqing has a shallow culture, and he knows very little about mathematics, physics and chemistry, so he can't find the cause of the problem at all.

At this time, he could only hold on and resist everyone's hopes.

More than ten minutes passed, and no one spoke in the venue, and the atmosphere was terrible for a while.

Li Yuanqing smiled and said, "Our blacksmith shop has already made so many qualified bird guns before, and this time, there are so many flaws at one time, it will never be a small problem." But it's also a good thing. At least, during the test launch, we found something wrong. If on the battlefield, not only you, but I, Li Yuanqing, also have to be responsible. Don't be nervous, think about it, what went wrong? One person counts short, and everyone counts long. Everyone brainstorms and don't be afraid to say the wrong thing. If anyone can find out the problem, I, Li Yuanqing, will immediately reward him with 50 taels of silver. ”

Hearing Li Yuanqing's words, there was a burst of discussion in the audience.

Something happened to the blacksmith shop, and everyone present was not in a beautiful mood.

They are all employees of the blacksmith shop, and they have to point to the blacksmith shop to make a living.

But Li Yuanqing did not directly pursue the responsibility, but promised a reward, which made the people present feel a lot more at ease, and they all used their brains to find a way to get through the difficulties.

At this time, an old craftsman said: "My lord, the little old man also feels that it may be a matter of iron." Otherwise, the bird gun will not explode. Although Xiao Lao'er is not an expert in making birds, he has been striking iron for decades. You can't go wrong. It's supposed to be iron. It is very likely that when these iron materials were being smelted at that time, something went wrong. ”

A young craftsman also said: "Adults, the little ones also agree with Old Man Wang's statement. We have also made a lot of bird guns before, and this kind of problem has not occurred. You see, this gun is so badly blown up, there is very little gunpowder in the fire door, even if it is blown up, it is difficult to blow it up like this. The pipe didn't look like it was made of iron, it looked like it was made of ice, and it shattered when you touched it. What's going on? ”

“……”

There was a lot of discussion among the people, but no one could say what was wrong.

Li Yuanqing relaxed a little.

People dare to speak, even if they can't find fault, but it's a good sign, at least people's hearts are stable.

"Don't worry, everyone. Can a living person suffocate to death? There are so many of us, let's figure it out together. I still don't believe it, this little thing can stump so many of us? ”

At this time, a short and thin junior disciple said, "Adult, small, small seems to have figured it out." ”

This apprentice is about fifteen or sixteen years old, less than one and a half meters tall, very thin, like a small radish seedling, which will fall when the wind blows.

As he spoke, he twitched the snot that came out of his nose vigorously, and looked at Li Yuanqing a little timidly, but hopefully.

Li Yuanqing couldn't help but smile, "This little brother, if you have any ideas, you just say it." Don't be afraid, even if you say it wrong, I'll treat you to dinner in the evening. ”

Li Yuanqing's soft approach made this junior apprentice very moved, tears were about to flow out, he cowered for a long time, then carefully stood in front, stammered and explained to Li Yuanqing and everyone: "My lord, everyone, all uncles and uncles, I think that this, this may not be a problem of iron, but a problem of heat." ”

As soon as he said this, everyone couldn't help but whisper.

Old Man Yang said: "Cao Tiehammer." Your father's skills are good. But you kid didn't learn half of his true biography. I don't blame you, but you can't talk nonsense. ”

Li Yuanqing didn't expect this little radish seedling to have the name of Iron Hammer.

Although he didn't have much hope for this kid, since he worked hard to stand up, Li Yuanqing still wanted to give him a chance.

Waving his hand to Old Man Yang, he said, "Old Man Yang, don't worry. Listen to him. ”

The little radish Miao Cao Tiehammer couldn't help but be grateful, and hurriedly knelt down and kowtowed to Li Yuanqing, then he ran over quickly, picked up a piece of bird wreckage and said, "Adult, the little one is not good at learning." But the little one has watched my father strike iron since he was a child. I remember, once my dad said that. In winter, you can use carbon to strike iron, but in spring, summer and autumn, it is better not to use carbon. Especially when making swords, you must not use coal. ”

The more he spoke, the more calm he became, he raised half of the gun to let everyone see, and said, "My lord, uncles and uncles, I don't know if you have seen the sword of the Wa Kingdom?" When I was a child, my dad accidentally got one and liked it very much. He said it was the strongest and sharpest knife he had ever seen. It just so happened that the owner of this knife had just returned from the Wa Kingdom. My father asked him, how did those Japanese people fight this knife? ”

At this time, everyone was attracted by Cao Tiezhu's words and pricked up their ears.

The man said that the Japanese people did not even have bellows, so they took charcoal and hammers and hammered them out little by little. My dad didn't understand it at the time. But later, he got another Jiannu's knife. This knife is rough, but it is sharper than my father's sword. My dad hasn't figured it out yet. After a few more years, I accidentally broke my father's stove, and my father could no longer burn coal, but only wood, but made a knife that was much sharper than usual. ”

When Cao Tiehammer said this, Xu Liang suddenly slapped his head hard, and exclaimed excitedly, "My lord, my lord, I figured it out." Hammer, you kid, you are, you are, who said you were stupid. You're smarter than anyone else. ”

Everyone didn't know why, and Old Man Yang was also inexplicable, and hurriedly said: "Xu Liang, what's going on?" ”

Xu Liang looked at Cao Tiehammer with a smile, "Tiehammer, you can talk about it." ”

Cao Tiezhu smiled shyly, "Uncle Xu, I, I can't say it, so you should come." ”

As he spoke, he hurriedly shrank behind Xu Liang.

Xu Liang looked at Li Yuanqing, Li Yuanqing smiled slightly and nodded.

Xu Liang hurriedly said: "The iron hammer is good, it's not a matter of iron. It's that we haven't mastered the heat well. In fact, it's not that we haven't mastered the heat well, but that we can't use coal to play this pipe. ”

Old Man Yang hurriedly said: "Xu Liang, this, why is this?" ”

Xu Liang picked up the half-cut pipe that Cao Tie Hammer had just dropped, and knocked on it: "You see, this pipe doesn't look like it's made of iron, but it looks like ice." This is because there is something unclean in the coal. In winter, because of the cold weather, the fire has to burn for a long time before it can be burned. During this time, these unclean things were burned. But in the past few days, the weather has warmed up. The fire doesn't have to burn for so long, so let's go straight to the iron. The dirt was not removed, and it melted into the iron. This time, even if it is made of fine iron, it will naturally not be so strong. ”

Li Yuanqing also figured it out at this time.

At this time, after all, it is not the afterlife, and the equipment is so advanced.

Coal contains a lot of chemicals, such as phosphorus, and there is not enough isolation equipment, so it is directly used to refine iron, and these substances are easy to directly react with iron, produce impurities, reduce the purity of refined iron, and greatly reduce the strength of refined iron.

And the traditional charcoal beating, which seems ancient and laborious, does not have these troubles.
