991, three irons in one
The two Dongfang brothers were taken aback.
Dongfang Junhua reached out to take the drawing, "You mean, wrap the soft iron with two layers of hard iron, and combine the three irons into one sword?"
Gu Qianxue nodded, "That's right! In fact, it is more appropriate to name the two pieces of hard iron with 'steel'. The pig iron with a lot of impurities is soft and malleable, so it is called iron. What martial arts pursue is a firm but soft, rigid iron." Softness and harmony, is it not possible to forge a sword?"
Dongfang Junhua was shocked, and murmured, "Hardness and softness, yes! The biggest problem we encountered in the past was that the extremely steel was easy to break, why not add a tough core to it?"
After getting along with Gu Qianxue for a long time, Jun An was used to Gu Qianxue's shocking ideas from time to time, and was less shocked. "Can the three pieces of iron fuse together?"
"In principle, it is possible, but whether it can be integrated or not depends on the technology and equipment." Qianxue said solemnly.
Different from Jun An's doubts, Dongfang Junhua was already eager to try, "It's okay, I'll try it, and I'll see if I can integrate." As he said that, he wanted to change his clothes and light the fire.
"Slow down, there's more to come." Qian Xue said.
Dongfang Junhua's eyes looking at Gu Qianxue can no longer be described as stunning. If he used to see a beautiful woman in his eyes, then what he sees now is a fairy, "Miss Zhao heard."
As soon as Gu Qianxue stretched out her hand, Chuyan handed over a cloth bag the size of a palm.
"This is?" Dongfang Junhua was puzzled.
"It's manganese ore." While speaking, Gu Qianxue untied the cloth bag.
Dongfang Junhua knows about manganese ore, and there are many mines in Mingjian Villa. This kind of thing is useless and poisonous. The villa stipulates that absenteeism should be avoided as much as possible, and the manganese ore that comes with the iron ore will be excavated to fill the old mine. "Ms. Zhao means to add manganese ore to iron? I'm afraid it won't work. In fact, for thousands of years, the ancestors of the villa have been working hard to improve the casting formula. Manganese ore has also been tried, but..."
"It's because the dosage is wrong," Qianxue interrupted him, "Add one part of manganese ore for every one hundred parts of iron ore, have you tried this dosage?"
Dongfang Junhua and Junan were surprised. There is such a huge disparity between one hundred iron ore and one manganese ore. What difference can it make if it is added or not
Gu Qianxue saw what they were thinking, and said, "Although the casting technology of Mingjian Villa is excellent, you have never thought that the excellent casting technology is not only unique to Mingjian Villa? Then why is the iron produced here so much better than other places?" Okay? Haven’t you ever thought about whether the gap lies in the material? The biggest feature of Mingjian Mountain Villa’s minerals is iron and manganese ore. Although you try to exclude manganese ore, in the formation of minerals for thousands of years, It is more or less fused, and it is precisely because of the fusion of iron and manganese that the iron in Mingjian Villa is different from the iron in other places, and the weapons cast are also different from those in other places."
Dongfang Junhua nodded, "About the material problem mentioned by Miss Zhao, the ancestors of the Dongfang family have long thought of it, but no one is sure. Maybe... just like Miss Zhao said, the problem lies in the manganese ore. If according to Miss Zhao's Meaning, because of the presence of traces of manganese ore, the iron in the villa is different from iron in other places; and because the impurities are smashed out during the casting process, but at the same time it also causes the lack of manganese, so manganese ore is added now, right? "
"That's right." Qianxue affirmed.
In fact, many special steels in modern times are widely used and made of high-quality materials. A piece of scrap steel taken out at random is much higher quality than the refined steel of this era. Some knowledge, but still indistinct, vague.
And the trace elements needed for real special steel are not only manganese ore? There are also tin ore, nickel ore, etc. Gu Qianxue doesn't want to embarrass herself anymore, a manganese ore is enough.
Jun An didn't know how to forge swords. Although he subconsciously wanted to refute, seeing that the fourth brother didn't speak, he obediently shut up.
Dongfang Junhua thought for a moment, then nodded, "Then let's try it." He said to Jun'an, "Fifth Brother, let's cast a small knife at the same time. You use iron ore, and mine add manganese ore."
"Okay." Without further ado, Jun An changed his clothes and lit the fire.
Because of the professionalism involved, Dongfang Junhua's eyes became less infatuated and more calm, "One hundred parts of iron, one part of manganese, is that right, Ms. Zhao."
"Yes." Gu Qianxue didn't know how much to add, so let's add 1% for now.
"Then let's try first, Miss Zhao and Miss Chuyan had better stay far away, otherwise it will be bad if the furnace smoke chokes you." Dongfang Junhua said softly.
"Yes." Without saying a word, Gu Qianxue ran away with Chuyan.
Gu Qianxue didn't stop until the other corner of the yard was far away from the two Dongfang brothers.
Chu Yan looked indifferently at the opposite corner of the courtyard, "Miss is shocked and feels guilty." It's not a question, but an affirmative sentence.
Qianxue glanced timidly, then sighed, and nodded, "Yeah, I can't do anything about it, Junan asked me to hide my identity, so I can't tell Dongfang Junhua that I was married, right? Many married women abandon their husbands and run out to participate in the Sword Forging Conference to show their faces, and the influence is not very good." He scratched his hair irritably.
Chu Yan sighed, "How about letting Jun An tell Dongfang Junhua that Miss has a sweetheart, and even a fiancé?"
Qianxue also suddenly realized, "Okay! Very good! That's it! Chuyan, you are so smart!"
Chu Yan smiled bitterly, smart? Where is she smart? If you are really smart, why can't you figure out your own affairs and make decisions
"The two of them are forging iron, what are we two doing?" Gu Qianxue became bored.
In this courtyard, it is not convenient to practice martial arts, and there are no books to read. There is a chess set on the side of the courtyard, but it is better to let Gu Qianxue play chess than to let her play iron, not to mention that Chu Yan does not look like a chess player. .
Chu Yan remained silent, not knowing what he was thinking.
Suddenly, Qian Xue had an idea, "How about we cook?"
"Cooking?" Chu Yan was taken aback.
"Yeah, it's been a long time since I made a matcha mille-feuille cake. I'm afraid I haven't eaten it yet. We're just idle. We happen to have a kitchen. Let's make cakes."
The corner of Chuyan's mouth twitched, but she wanted Gu Qianxue to say that Jun'an had never tasted it, and her heart was ready to move, "Slaves listen to Miss."
Ever since, the two started making cakes.
In a flash, half a day passed like this, and it was already afternoon.
Because of the urgent time, Jun'an and Dongfang Junhua didn't stop for lunch, and made the knife for breaking their promise in one go.
At the same time, Gu Qianxue and Chuyan's matcha mille-feuille cake was also freshly baked, and it was warm when it was soft and delicious.
When the two came to the casting table with the cake, they heard a crisp sound, followed by Dongfang Junhua's surprised voice, "It's amazing! It's really amazing! Ms. Zhao is really a genius, to be able to invent such a recipe! "
