The journey of the film and television world is endless [continued]

From that day on, Buma took Liu Yuan to many places. In fact, as the residence of the lord, the castle has quite a lot of supporting craftsmen serving the lord. Some people have even been doing this work for generations and have their own independent studios. For example, leatherworkers, blacksmiths, tailors, carpenters, silversmiths, coopers, animal trainers, chefs, grooms, potters and bakers, etc.

However, due to Liu Yuan's sleepiness, he was not qualified for many jobs. Finally, Bulma found Parker, a childless blacksmith. At first, the old man was not very happy. But when he saw that Liu Yuan, who was only five years old, could easily lift a hammer weighing about ten pounds with one hand and swing it quite easily, old Parker happily agreed to let Liu Yuan be his blacksmith apprentice. In this world, the inheritance of knowledge and technology is very precious.

Take blacksmiths for example, they usually also make weapons and armor. If you want to learn these skills, you not only have to work for the master for many years for free, but also have to pay a very expensive apprenticeship fee. Even if you have learned the skills, you still have to give a part of your wages to the master.

For this, Bulma took out her savings, a bag full of copper coins, worth about 1200 copper coins. Parker accepted the money, and since then, Liu Yuan has followed him to learn blacksmithing skills. Due to his special situation, he does not have to live in the blacksmith shop. Old Parker may be old and wants to teach another apprentice. Although Liu Yuan is still young, he still teaches patiently, such as how to determine the temperature of molten iron! How to choose iron materials, forging different tools, and using different materials. Basically, every experienced blacksmith has his own unique techniques.

The old blacksmith found that the apprentice was very smart. He could remember many things as long as he was told once, and he could master some technical techniques very quickly. Even some of the suggestions he occasionally made benefited him a lot, which made him very happy.

Liu Yuan discovered that the skills he had mastered before had actually revived. For example, the skills of the former blacksmith had been upgraded to the master level by the system. Now, in the process of continuous learning, he clearly felt that his body was gradually adapting to various skills. This made him fall into deep thought. Since the blacksmith's skills can be inherited, what about other skills?

With this idea in mind, he looked around but couldn't find anything suitable. He had no choice but to pick up small stones and throw them at the firewood pile not far away. After a simple adaptation, he could hit the target every time and even throw in different ways.

From this, Liu Yuan could be sure that all his skills were imprinted on his soul. As long as his physical strength could keep up, one day he would be able to use his fingers as easily as before. This made him feel more at ease. He just needed to get through this weak period with peace of mind. He had enough confidence that no matter what kind of world he was in, he could make a name for himself.

-------------

In the spring of the 281st year of the Aegon calendar, another year had passed and Liu Yuan was almost six years old. He always felt that there was something wrong with this world. The winters had not been cold for several consecutive years, and even the coldest time was only two or three degrees below zero.

He had asked people around him, but still couldn't get a definite answer. It might be that the people he met had a narrow range of knowledge, and many of them had never left the castle within 30 leagues (a unit of measurement in this world, one league is roughly equal to 4700 meters). And the only scholar in the castle, Bachelor Wells, had never come to see Liu Yuan since his physical transformation was completely finalized, and his original plan to study with him was also ruined. Strictly speaking, Liu Yuan was still illiterate and could not understand the words of this world at all.

He is now helping out at the blacksmith shop. Old Parker recently received a big job. Sir Bandir spent four gold dragon coins to order a full set of armor from him. This set of armor includes: top-grade mail, throat guard, greaves, hand guards and a full-cover helmet. This is a big deal. One gold dragon coin is equivalent to a copper penny. And one copper penny can buy a grilled sausage and a small cup of beer at the Boar's Tooth Tavern in the port.

Old Parker's exquisite craftsmanship is beyond doubt. The most difficult part of this set of armor is the chain mail. Chain mail must be made of high-quality iron, because the wire drawing process must use wrought iron. If the iron material has a high carbon content, too many impurities or uneven smelting, it is impossible to draw wire.

Liu Yuan discovered that the purity of iron ore in this world is still very high, and it only needs simple refining to meet the requirements. The wire drawing process is to forge the iron block into the smallest possible iron bar, and then use a wire drawing die to draw the wire. Liu Yuan made a small suggestion to change the wire drawing template to a multi-hole one. In this way, multiple iron bars can be processed at the same time, which greatly improves work efficiency.

Each time the formed iron bar is stretched, the diameter of the iron bar will decrease. After multiple wire drawing, it becomes a thin iron wire. Because of the cooling and hardening phenomenon, annealing should be performed after several wire drawing.

In this era, annealing was usually done in a pottery jar, with some charcoal and animal fat (fish oil was used because the area was located by the sea), and then the pottery jar was sealed. A small hole was left at the seal, and then a second calcination was performed. The oil and carbon powder in the pottery jar could effectively prevent air from entering the jar, causing oxidation and failure of the iron wire.

After the annealed iron wire, the wire drawing operation can be carried out again. Next, the iron wire needs to be cut and bent into a ring, and the ring part needs to be flattened and rivet holes are punched. In this way, the ring is ready. Liu Yuan designed a mold that can forge 50 iron rings at the same time. The construction period was reduced to one-third of the previous time, and the old guy was so happy that he couldn't close his mouth.

Next, the iron ring needs to be carburized and quenched. Otherwise, it will not be hard enough to withstand the knife. As for the next step, it is a unique skill. In fact, every blacksmith has a different way of quenching. Old Parker did not shy away from Liu Yuan and operated in front of him. Carburizing and quenching also use a pottery pot filled with iron rings, and then add animal blood, urine, charcoal, grease, etc. After sealing the mouth, leave a small hole and then calcine. After calcining, throw it into the water together with the pot to cool.

The ring that is taken out again is the iron ring that has been carburized and quenched. However, quenching alone can only increase the hardness, and in order to improve the toughness, it must be tempered. Tempering only requires simmering at a low temperature for a period of time, and after simmering, the iron ring becomes a finished product.

The last step is to weave the iron rings into armor, and then rivet the small holes on each ring, and it will become a finished chain mail. Liu Yuan is now weaving the armor. His movements are very fast. After stringing the chain links, he will use the small pliers in his left hand to seal them. This is a long chain mail with long sleeves that hem below the knees. It is more than 70% completed. Old Parker is making a helmet, which is a flat-topped pot helmet. While he was working, he boasted to Liu Yuan: "Galon! You don't know, when I was young, I crossed the Narrow Sea and went to study in Cohor on the other side. The master craftsmen there can recast magic alloys and infiltrate pigments into metals. I learned a few tricks back then. When you grow up, I will teach you."

At this time, a fat boy pushed open the door and rushed in. When he saw Liu Yuan, he immediately ran over and said anxiously: "Galon! Mom asked me to tell you that Aunt Bulma has fainted. You should go home and check!"
