Ji Kang, who was a leader of the Seven Sages of the Bamboo Forest, was not only a masterpiece of Guanglingsan, but also a masterpiece of the iron.

Ji Kang: I haven’t made a blacksmith for a long time, and I’m just itchy!

Li Qing (Rudolph): Laugh, the opportunity is here for the boss.

Ji Kang: Thank you, little brother.

When Rudolph returned to the camp and when night fell, Fein still did not come to Rudolph's camp. Instead, Rudolph was a little unable to sleep.

"It's not that he failed to show off, right?" Rudolph paved anxiously in the tent. He thought to himself that the other party would not have believed in him at all.

"Master Rudolph, Lord Rudolph." At this time, Maxiu's voice sounded from outside the tent. He was the one who was responsible for patrol and duty today.

"What's up?"

"Someone outside the camp said he was coming to see you, and he said he was a blacksmith." Ma Xiu reported immediately.

"Blacksmith?" Rudolph uncovered the curtain of the tent and said to Maxiu.

"Hu, hu, hu~~." The skin breeze kept blowing the wind into the stove. As the color of the flames in the wind gradually changed, the torches in the house were not as bright as those in the stove. The shadows of the four people swayed on the walls in the house.

"This bellows are not very good!" Rudolf, no, he, who had transformed into Ji Kang at this time, was shirtless, holding an iron hammer in his hand, and looked at the compressed leather cage next to him and said.

"Sir Rudolph, what are you talking about?" Ma Xiu, who was accompanying the guard, asked in surprise, because Rudolph seemed to have spoken language that he could not understand at all.

"Clang~~." At this moment, the red iron block was picked up from the stove with iron pliers. Rudolph raised the hammer and hit it violently, and sparks suddenly burst into pieces.

"What amazing skills do you have? Let me see, don't just brag about the nobles." The blacksmith Fein stood aside, watching Rudolph grinding the red cast iron one after another.

"Clang, CLlang, CLlang~~." As the hammers kept hitting, the red cast iron on the iron felt was changing. Fein narrowed his eyes and looked at Rudolph who was thundering. For some reason, this iron-thrusting nobleman actually exuded a strange temperament, a noble like the legendary Vulcan God.

"What is this?" Suddenly, Rudolph said curiously as he watched the blacksmith's apprentice fill some black stones into the stove.

However, Ma Xiu, Fein and others did not know what he was asking, but Li Qing, who was subconsciously, helped Ji Kang answer.

Li Qing (Rudolph): This is coal, a fuel better than charcoal.

In fact, the forging technology of ancient Europeans was not much higher than that of the East, but they had an innate advantage, that is, many places in Europe produce high-quality coal. This fuel, which is better than firewood and charcoal, can maximize the forging, and of course, the weapons produced are even better.

"This thing is very good." Ji Kang couldn't help but say that as an intellectual who knows how to make iron, being good at analysis and research is his characteristic.

"I didn't expect that Lord Rudolph actually knew how to make ironwork." Ma Xiu, who was watching from the side, looked at Rudolph among the ironworks. He was a little surprised. Although he didn't know much about ironworks as a villain, he would occasionally stop in front of the blacksmith shop when wandering around every day. So those skilled blacksmiths can basically judge how the blacksmith's skills are?

"Today I prepared ordinary water for this nobleman. Let's see what he can do?" Fein looked at the red cast iron repeatedly knocking on the iron felt, and the pig iron had gradually changed from red to dark red. Experienced blacksmiths understood that this was the reason for the temperature drop. Europe's latitude was higher, the climate was colder at night, and the cooling rate would be faster.

When watching Rudolph's iron-smashing technique, Fein couldn't help but admire the strange young nobleman. His technique was very skillful and he was completely a veteran of iron-smashing. But Fein knew that the most important thing was not the iron-smashing technique. To create high-quality iron, the key was the cold iron link. Ordinary blacksmiths used cold water to cool it directly. However, the reason why Fein was able to create high-quality iron was that his trick was to add resin and animal blood to the cooled water. When the iron was cooling, some wonderful elements would penetrate into the iron, making the iron created more tough.

"Huh." Just as Fein was about to see how Rudolph built it, Rudolph stopped. He stared at the gradually changing pig iron with his eyes. The apprentice who was blowing on the side looked at him in surprise, thinking that he didn't know the next quenching link, so he put the wooden barrel filled with cold water next to him.

But Rudolph did not move. He stood steadily next to the iron felt, watching the pig iron turn back to its original color. What was going on? Maxiu and Nord looked at each other in an incomprehensible way. This seemed completely different from the foggy iron they knew.

"Kang." When the pig iron changed back to its original color, Rudolph picked up the pig iron and threw it back into the stove. The pig iron turned red again under the high temperature of the stove.

"Is this?" Nord opened his mouth, trying to warn Rudolph if the young nobleman had forgotten to cool it with cold water, but when the cast iron turned red again, Rudolph took the iron block out of the stove with iron tongs and pounded it on the iron felt.

"Hiss~~." At first, the stubborn Fein thought Rudolph had forgotten this part, but when Rudolph kept repeating this move, slowly Fen felt that things did not seem simple. Judging from Rudolph's skillful ironwork, this may really be a new technology.

Time passed little by little, amid the monotonous sound of ironwork, at about three or four o'clock in the morning, the moonlight in the sky shone in from above the room, and Rudolph stopped smacking.

"I'll leave!" After Ji Kang threw down a sentence, he fell deeply into his subconscious mind. The moment he returned to his body, Rudolph only felt his arms sore and weak, but fortunately, Rudolph's physical fitness was pretty good.

"Is it done?" On the side, both Maxiu and Nord woke up from a confused state. Maxiu leaned against a pillar in the house and was napping, while Nord sat on an empty wooden barrel and napping against the wall.

"God! Incredible." Fein's eyes were red. He did not look away from this forging for a moment. When the repeatedly forged iron finally appeared before him, he was shocked. This color and method he had never seen before made him believe in the oriental technology that Rudolph mentioned.

"It seems that what Ji Kang lost was not only Guangling San, but also this cold forging method." Rudolf also sighed, regretting the premature death of the seven sages of the bamboo forest.

The iron forged by Ji Kang was in a black state, unlike the iron made by ordinary people. This forging technology that did not require cold water to cool and naturally annealed should have appeared in the Sui and Tang dynasties, but for some reason Ji Kang discovered this forging method.

"Kang~~." Fein picked up the black iron that had been made into a long strip, and then picked up a piece of iron that he had forged, and hit the two irons together. Suddenly, a crisp metal collision sounded, and the iron made by Fein broke into two pieces.

"Hahaha." Maxiu laughed wildly and slapped Nord on the body, almost slapped the fat Nord to the ground.

"How is it?" Rudolph said with a smile at Fein.

"I'm convinced, is this really Eastern technology?" Fein looked at the facts in front of him, lowered his head and said to Rudolf.

"Yes, Fein, don't forget our bet, you are mine now." Before Rudolph showed Fein's skills, the two bets that as long as Rudolph could forge ironworking skills beyond Fein, Fein would willingly serve Rudolph and become one of his servants. If Rudolph lost, he would have to pay Fein's 100 large silver coins.
