Although he has been upgraded to a fifth-level trainee knight, Abel's spirit is still very low. Master Bentham saw his appearance and hurriedly asked him to have a good rest. Knight Marshall led Abel out of the blacksmith shop and walked outside.
After walking out of the blacksmith shop, he saw the carriage specially designed for Knight Marshall speeding from a distance. Abel couldn't help but look down at the knight's boots. They were covered with mud. It took more than 20 minutes for the carriage to go from the castle to the blacksmith shop. However, Knight Marshall couldn't wait any longer and ran over in order to get there quickly.
You must know that Knight Marshall is a fiefdom noble. It is very embarrassing to run wildly in his own territory, but Knight Marshall did it for Abel.
Abel looked at the happy-looking Marshall knight. This particularly good-looking knight was in a mess, but he was happy for his upgrade. He couldn't help but feel warm in his heart, and said softly: "Uncle Marshall, thank you for everything you have done for me. "
"What are you kidding for?" Knight Marshall patted Abel on the head and pulled Abel into the carriage, which ran towards the castle in the sunshine.
"Ding, ding, ding." Abel had already arrived at the blacksmith shop early the next morning and asked Master Bentham for a separate operating room. The master knew that this was Abel's first time making a big sword. I didn’t want to be disturbed, so I agreed.
Abel's idea was that he didn't want others to see how he was building this sword, because he was going to use some techniques that he had never seen anyone else use here, carburizing and quenching techniques that he learned from earth science programs.
The rough blank of the sword needs to be continuously tempered to reduce the carbon content. The less the carbon content, the higher the quality of the rough blank. However, if the formed sword is carburized and some carbon is added to the blade, the hardness of the sword can be improved.
Abel put the formed sword into a crucible. This crucible was specially made by someone. It could just fit a big sword into it. It had been prepared a few days ago. The big sword in the crucible Cover the top with charcoal, black beans, and soil powder, then seal the crucible and place it in the stove for heating.
Charcoal and tempeh are naturally used for carburizing, and soil powder is still a dispersant. The advantage of this carburizing technology is that the carburization obtained by the sword is very uniform and stable, the carbon potential is very high, and the efficiency and effect are quite good. In fact, this technology is still used on modern earth, it is the so-called "steel stewing method".
Speaking of quenching, there is also a corresponding technology for quenching in this world, which is to throw the sword into cold water for rapid cooling, but this also leads to a large increase in the scrap rate. Because of the rapid thermal expansion and contraction from hot iron to cold water, the internal stress in the metal is unbalanced during quenching, causing the sword to crack when it is placed in cold water. Sometimes, even after passing quenching, cracks will appear for a period of time after being taken out. .
The quenching technology used by Abel this time is a relatively special quenching technology. It is a new method for practicing ancient swords in science programs. When the long sword is taken out from the crucible, it is first rubbed back and forth on the charcoal to allow the charcoal to Completely contact the sword body, and then put it into the quenching bucket. Half of the bucket is water and the other half is animal fat. The sword, which has been burned to nearly a thousand degrees, first enters the animal fat. A large amount of heat is first absorbed by the grease. It is absorbed, but the heat transfer speed of animal fat is not fast, and the sword will not be affected by the stress. Then it enters the cold water. The temperature is not as high as before. The sword is quenched in the cold water for the second time.
After the sword was cold, he took it out of the quenching bucket. Abel flicked the sword surface with his hand, and the sound was crisp. Although the quality of the sword was unknown, the sword was already made.
He called the servants to clean up everything in the operation room. Abel didn't want people to think of these things. Inventing and creating in this world is a very dangerous thing.
"Garden, can you help me find someone to make the sword handle?" Abel found Garden who was busy and asked a little embarrassedly.
Some of the sword handles were made of iron or wood, and some were made of horn or other relatively hard materials. Abel had never learned the craft of carving sword handles, so he had no choice but to come to Garden for help.
"Is this the first big sword you have made?" Garden took the big sword from Abel's hand, looked at it carefully, and said in a hoarse voice with excitement: "Is this the Hundred Practices Big Sword? Oh my God. , This is the Bailian Great Sword.”
Garden has been studying here with Master Bentham for five years, and he can only forge 60 skills. A hundred skills has always been Garden's dream.
"Master Abel, you are really a genius." Garden praised sincerely, and then gently stroked the sword body with his hand. He seemed to have discovered something. He flicked the back of the sword with his fingers and put his ear against the back of the sword. Listening to the echo of the great sword.
"This is impossible, how could such a thing happen?"
This sword has the performance of hundreds of practices, but the hardness of the sword body is much higher than ordinary hundred practices swords. Master Bentham will make a hundred practices sword every month. These hundred practice swords are Harry Castle One of the sources of wealth, Garden not only watched the masters making swords, but also maintained these hundred-level swords, so his familiarity with the hundred-level swords was much higher than that of others.
The appearance of Abel's big sword is very strange, and it is very different from the Bai Lian sword that the master usually makes. Garden can't explain clearly what is the difference, but experience tells him that this sword is better than other Bai Lian swords. Practice the sword.
To test this, Garden slashed his sword at a piece of wood that was to be used as fuel. Almost effortlessly, the sword slid through butter like a hot knife, silently splitting the wood into two pieces.
"How did you make this big sword?" Garden was a little anxious to know about this sword.
"I just forged it according to your instructions. Master Bentham helped me when I encountered difficulties." Abel explained.
Garden seemed to have misunderstood that the sword was so good because Master Bentham helped Abel complete the final part. He couldn't help but secretly determined that he must learn from the master well so that he could forge such a weapon in the future.
"I have collected some very good horns, which can be used as handles for big swords. I will help you put them on and scabbard them in the evening. Can you keep this sword with me?" Garden had a very interesting idea. Simple, the forging method of this sword is very strange. If you can study it for one night, it will be very beneficial to your forging skills.
Garden stayed up all night that night. He used the best horn to install the handle of the sword, and found a crocodile leather scabbard. After that, he carefully observed this strange sword in front of an oil lamp.
In the morning, Garden came to the blacksmith's shop with his big sword. His observations all night made him extremely surprised. If it weren't for the fear of breaking Abel's sword, he would have wanted to take it with Bai Lian in the master's warehouse. Cut with the sword.
"Garden, what's wrong with you?" Master Bentham couldn't help but wonder when he saw Garden with red eyes. Why did Garden, an honest man, seem to have not slept all night.
"Master, I can't understand the sword you helped Abel make. I thought about it all night last night." After touching his head, Garden looked at Master Bentham with some embarrassment, wondering if he was too stupid.
Master Bentham took the big sword and pulled it out while saying: "This is the big sword that Abel forged yesterday. I just taught him how to train the rough blank at 100 levels the day before yesterday. When you reach the 80-level bottleneck, I will teach you too."
"Is this the big sword, the one forged by Abel?" Master Bentham was also a little surprised. The master's experience is much higher than that of Garden. The technology contained in this big sword can be said to belong to a family. Secret techniques, secret techniques that improve the hardness and sharpness of weapons. Although the master is very tempted by such secret techniques, he knows that spying on a family's secret techniques means forming a deadly feud with that family, regardless of whether the secret technique belongs to the Harry family. , or from the Bennett family.
No wonder Abel asked to use a separate operating room yesterday. It turned out that Abel wanted to use the family's secret technique to refine the sword. This makes Abel's behavior understandable.
Master Bentham warned Garden not to ask Abel about this matter, as if it never happened.
