Although Abel had leveled up to a level five novice Knight, his spirit was still very weak. When Master Bentham saw him like this, he hurriedly asked him to take a good rest. The Knight Marshall led Abel out of the blacksmith's shop and walked outside.
When they walked out of the blacksmith's shop, they saw the Knight Marshall's carriage from afar. Abel couldn't help but look down at the knight's boots, which were full of mud. It took more than 20 minutes for the carriage to travel from the castle to the blacksmith's shop, but the Knight Marshall couldn't wait and ran over himself in order to arrive as soon as possible.
The Knight Marshall was a noble, and running around in his own territory was very embarrassing. However, the Knight Marshall did it for Abel.
Abel looked at the happy face of the Knight Marshall. This knight was very proud, but he was happy because of his leveling up. Abel couldn't help but feel warm in his heart. He said softly, "Uncle Marshall, thank you for everything you've done for me."
"Don't think too much, kid." The Knight Marshall patted Abel's head and pulled Abel into the carriage. The carriage ran towards the castle under the sun.
"Ding, ding, ding." The next morning, Abel came to the blacksmith's shop early and asked Master Bentham for a separate operation room. Master Bentham knew that this was Abel's first time making a big sword, so he didn't want to be disturbed, so he agreed.
Abel didn't want others to see how he made this big sword, because he had to use some techniques that he had never seen before, such as carburizing and quenching techniques that he learned from science programs on Earth.
The rough sword needed to be constantly tempered to reduce the carbon content. The lower the carbon content, the higher the quality of the rough sword. However, after the sword was formed, if some carbon was added to the blade through the carburizing method, the hardness of the sword could be increased.
Abel put the finished sword into a crucible, which had been specially made to fit the sword, and had been prepared several days before. He covered the sword in the crucible with charcoal, fermented beans, and soil, sealed the crucible, and heated it in the stove.
The charcoal and fermented beans were naturally used for carburizing, while the soil powder was still used as a dispersing agent. The advantage of this carburizing technique was that the carburizing of the sword was very uniform and stable, and the carbon potential was very high, so the efficiency and effect were quite good. In fact, this kind of technology was still used on Earth in modern times. It was the so-called "stewing method".
Speaking of quenching, there was a corresponding technique in this world, which was to throw the sword into cold water to cool it down quickly. However, this also led to a huge increase in the rate of scrap. Because of the rapid thermal expansion and contraction from hot iron to cold water, the internal stress in the metal would be unbalanced during the quenching process, causing cracks to appear on the sword when it was placed in cold water. Sometimes, cracks would appear even after the quenching process was taken out for a while.
The quenching technique Abel used this time was a relatively special one. It was a new method that Ancient Sword learned in the science program. When the sword was taken out of the crucible, he first rubbed it back and forth on the charcoal so that the charcoal could completely touch the sword. Then, he put it into a quenching bucket. Half of the bucket was water, and the other half was animal fat. The sword that was heated to nearly a thousand degrees Celsius first entered the animal fat. A large amount of heat was first absorbed by the fat, but the heat transfer speed of animal fat was not fast, so the sword was not affected by the stress. Next, it entered the cold water. The temperature was not as high as before, so the sword was quenched a second time in the cold water.
When the sword was cold, Abel took it out of the quenching bucket. He flicked the surface of the sword with his hand, and the sound was very crisp. Although he did not know the quality of the sword, the sword was already made.
Abel called the servants to clean up the things in the operating room. He did not want people to think of anything when they saw these things. It was very dangerous to invent something in this world.
"Gedon, can you help me find someone to make a sword handle?" Abel asked Gedon, who was busy working.
Some sword handles were made of iron, wood, and some were made of horns or other hard materials. Abel did not learn how to carve a sword handle, so he could only ask Gedon for help.
"Is this the first sword you made?" Gedon took the sword from Abel's hand and looked at it carefully. He said with a hoarse voice, "This is the sword of a hundred skills? Oh my god, this is the sword of a hundred skills. "
Gedon had been learning from Master Bentham for 5 years, and he could only forge 60 skills. 100 skills had always been his dream.
"Young master Abel, you are a genius." Gedon praised from the bottom of his heart. He then gently stroked the body of the sword with his hand. He seemed to have found something. He flicked the back of the sword with his finger and put his ear to the back of the sword to listen carefully.
"This is impossible. How is this possible?"
This sword looked like a sword of a hundred skills, but the body of the sword was much harder than a normal sword of a hundred skills. Master Bentham would make a sword of a hundred skills every month. These swords of a hundred skills were one of the sources of wealth in Harry Castle. Gedon had not only watched Master Bentham make swords, but he also took care of them. Therefore, he was much more familiar with the sword of a hundred skills than other people.
The surface of Abel's sword was very strange. It was very different from the sword of a hundred skills that Master Bentham usually made. Gedon couldn't tell what the difference was, but his experience told him that this sword was better than other swords of a hundred skills.
To prove this point, Gedon chopped the sword into a piece of wood that was going to be used as fuel. It was almost effortless. The sword was like a hot knife through butter, and the wood was silently split in half.
"How did you make this sword?" Gedon was a little impatient. He couldn't wait to know about this sword.
"I was just following your instructions. When I was in trouble, Master Bentham helped me." Abel explained.
Gedon seemed to have misunderstood that this sword was so good because Master Bentham helped Abel finish the last part. He couldn't help but secretly make up his mind. He must learn from Master Bentham so that he could make a weapon like this one himself.
"I've collected some very good horns. They can be used as the handle of this sword. I'll help you install it tonight and help you equip it with a scabbard. Can you leave this sword with me?" Gedon's idea was very simple. The forging method of this sword was very strange. If he could keep it for a night to study it, it would be very good for his forging skills.
Gedon didn't sleep that night. He used the best horns to install the handle of the sword and found a scabbard made of crocodile skin. After that, he carefully observed this strange sword in front of the oil lamp.
In the morning, Gedon brought the sword to the blacksmith's shop. After a night of observation, he was very surprised. If it weren't for the fact that he was afraid of breaking Abel's sword, he would have taken this sword and cut it with the sword of a hundred skills in Master Bentham's warehouse.
"Gedon, what's wrong with you?" Master Bentham saw Gedon's red eyes and couldn't help but feel a little strange. Gedon was an honest man, so why did he look like he didn't sleep the whole night?
"Master, I don't understand the sword you made for Abel. I've been thinking about it for the whole night." Gedon scratched his head and looked at Master Bentham with a little embarrassment, wondering if he was too stupid.
Master Bentham took the sword and said as he pulled it out, "This is the sword that Abel forged yesterday. I only taught him how to forge the base of a hundred skills the day before yesterday. When you reach the bottleneck of 80 skills, I'll teach it to you too."
"This is the sword that Abel forged?" Master Bentham was also a little surprised. The master's experience was much higher than Gedon's. The technique contained in this sword could be said to be a secret technique of a family. It could improve the hardness and sharpness of a weapon. Although the master was very tempted by this secret technique, he knew that spying on a family's secret technique would make him an enemy of that family. It didn't matter if the secret technique was from Family Harry or Family Bennett.
No wonder Abel asked to use a separate operation room yesterday. It turned out that Abel wanted to use his family's secret technique to forge the sword. This explained Abel's actions.
