The 100 steelmaking process is simply to repeatedly heat, fold and forge the smelted iron sand or high-carbon fried steel, and finally obtain the knife strip with the impurities of oxides in the steel and carburizing. Pen & Fun & Pavilion www.biquge.info

The steel composite process is to connect the steel blocks with different carbon content through different levels of forging, and the knife is made stronger by heat treatment and quenching technology, and the grinding technology makes the knife body more exquisite.

Jian Yong failed to find a blacksmith, only a few blacksmith apprentices, Liu Bei was angry and selected dozens of weak-crowned teenagers from the Liu clan to learn from the blacksmith brought by Zhang Shiping, originally Zhang Shiping looked at the dozens of ignorant teenagers in front of him and frowned: "Xuande, blacksmith is easy to do, but knife caster is not easy to do."

In order to have his own knife caster, Liu Bei asked Jian Chun to grind walnuts into powder for dozens of teenagers to drink, and specially planted a few walnut trees for this purpose.

More than a month has passed, dozens of teenagers have been able to initially cast knives successfully, each person only learns one or a few processes, the burning of fire, the forging of forging, the quenching of quenching, the carburizing of carburizing, and the grinding of grinding.

Zhang Shiping was stunned by Liu Bei's approach, and asked in surprise: "How did Xuande come up with such a method?"

The assembly line operation was used in the Qin Dynasty as early as the Qin Dynasty. Liu Beitui said: "I saw it in an ancient book, and the bow and arrow workshop of the Qin Dynasty did this."

Zhang Shiping looked strange and suspicious, but how to explain it He suddenly thought of this way of working, you must know that the Zhang family has been a knife maker since the Western Han Dynasty.

One hundred and fifty skulls and several hook-inlaid shields have been cast, and Zhang Shiping has already figured out the temperament of the iron of the stars and began to cast divine weapons.

Zhang Fei's Zhangba Snake Spear, Guan Yu's Qinglong Yanyue Knife, Liu Bei's Two Ribbon Knives, and Han Dang's Dragon Bird Dahuan Knife are all doped with the iron of the stars, and the original 1,200 catties of pig iron have been exhausted, and these 300 catties of pig iron are Zhang Shiping's reward for giving him the remaining star iron in order to thank Liu Bei.

The best ratio of the iron of the stars to pig iron is ten to one, so Liu Bei only needs to give out thirty catties of the iron of the stars, in order to retaliate against Zhang Shiping for calculating himself, Liu Bei only moved thirty-two catties from the mine, but there are more than two catties left Zhang Shiping can not be happy himself.

After the soldiers supported by the Zhang and Su clans in Zhongshan came to Liu's Wu Fort, Zhang Shiping stayed for a few more days, instructing the Liu clan to refine the iron ore they had collected by themselves, carburizing until the suitable steel quality was fried, and then led the convoy back to Zhongshan.

Liu Bei was a little dissatisfied with his nominal uncle, Zhang Shiping had nothing to do with him, he had already donated 1,500 catties of pig iron, and helped him cast 150 skulls and hook inlaid shields and steel-making, casting knife production lines, and he not only did not produce anything but ate and drank every day, but also had to take Liu Bei's hundreds of bamboo guns, more than 100 mulberry bows and tens of thousands of bamboo arrows. Therefore, when Su Shuang left, Liu Bei behaved a little coldly.

Liu Yuanqi looked at Liu Bei and asked, "Is Xuande angry with Duke Su?"

"Nope."

Liu Bei refused, and wondered: Could it be that I am so obvious, it seems that my skin is still too thin?

Liu Yuanqi smiled strangely: "Xuande went to ask Xianhe, how many good things did Su Gong leave for you?"

Liu Bei walked into his house suspiciously, Jian Yong walked straight with a smile on his face, and saw Liu Bei shouting happily: "Xuande, my uncle is really generous."

"Oh! What good things did my uncle leave behind to make Kenwa so happy? ”

Liu Bei's flat expression made Jian Yong a little disappointed, but he still said: "A large number of cow tendons, lacquer, animal horns, silk, the most precious is more than a dozen bow masters."

"Master Bow Maker?"

Although Liu Bei strongly suppressed the joy in his heart, the corners of his eyebrows still revealed endless joy: "Take me to see it."

I? Jian Yong glanced at Liu Bei, she was overjoyed!

"I've seen the head of the house."

As soon as Liu Bei entered the eyes of those bow-making masters, several people quickly stood up and saluted.

"The head of the house?"

"Exactly, the head of the Su family has already given the eyes to the head of the family, this is the deed."

An old man with snow-white hair carefully took out a stack of animal skins from his arms and handed it to Liu Bei.

Liu Bei took the animal skin and thought about it, and then handed the animal skin to Jian Yong: "Since you are all bow masters, as long as you teach a bow making master, you can go back from here, and each additional one will be rewarded with ten gold, and each bow made will be rewarded with an additional piece of corn."

The old man in front of him trembled with excitement when he heard this, his beard trembled, and he didn't say anything for a while, and a thirty-year-old man behind him said, "The head of the family can be serious."

"I have never said that this elder is your elder! Brother Xianhe returns the identity deed of the elder to the elder, and as for the identity deed of the others, you can accept it first, and return it to him when someone is qualified enough to bring the apprentice. ”

"No!"

Although Jian Yong was a little afraid that these bow masters would not be able to control it if they took the deed, Liu Bei had already said it, and it was not good for him to refute Liu Bei in front of everyone.

The old man took the deed handed by Jian Yong, knelt on the ground with a puff and said in a trembling voice: "The old man Su Yigong thanked the master family for his son and nephew first, the master family can rest assured, the old man will definitely do his best to teach the disciples to repay the kindness of the master family."

The bow making workshop slowly moved from a dozen sheets a day at the beginning to dozens a day, when all the ingredients were ready.

"Sima, Zhang Junhou and Brother Guan have already arrived three miles away."

A big **dust servant wearing a reed armor, carrying a mulberry bow, and holding a bamboo gun stepped into Liu Bei's mansion and shouted.

"Really?"

Liu Bei came to the door of the dock fort and saw a puff of smoke and dust coming from afar, riding on a black horse (Su Shuang left five hundred horses and the previous claw lightning flying yellow hybrid) towards the smoke and dust, behind him dozens of bodies carrying two stone big yellow bows, hanging swords from the waist, holding bamboo guns with bamboo and wood as the head of the bamboo gun and other new equipment of the white soldiers.

"Yun Chang, Yide."

Liu Bei shouted from afar, and Guan Yu and Zhang Fei saw Liu Bei coming up in person.

When the distance between the three of them was 100 paces, Liu Bei suddenly dismounted and strode towards the two, Guan Zhang and the two also turned over and dismounted, Liu Bei grabbed the palms of the two and asked, "Is it going well along the way?"

Zhang Fei said with a big grin: "Don't worry, brother, don't you think we're back well?"

Liu Bei's performance made Guan Yu's heart hot, and in the past few years since he wandered the rivers and lakes alone, he has seen what it means to be sinister and unpredictable, and he also knows that his feelings are deep. But it didn't happen to him, and now he is cared for by Liu Bei, and he is very excited: "Thank you Brother Xuande for your care, and I and my family will return safely."

"Oops! It's awkward to death! It's so hypocritical, since the three of us are so attached, it's better to worship as brothers. ”

Zhang Fei blinked and said, Liu Bei, who didn't know how to enter the Taoyuan Righteousness stage, agreed.

Guan Yu was overwhelmed by Zhang Fei's whimsical thinking, and when he saw Liu Bei agree, he looked at himself and nodded subconsciously.

Liu Bei saw Guan Yu nodding, for fear that he would regret it, and said: "There is a peach blossom forest on Yidezhuang, and now it is the season when the peach blossoms are in full bloom, which is just right for our brothers to worship."

Guan Yu was stunned: "It's too late today!"

Zhang Fei was also a little confused, God knows that he just said casually: "That is, uncle, aunt and sister-in-law haven't settled down yet?"

Liu Bei said in an irrefutable tone: "Then tomorrow."
