Zhang Shiping and Su Shuang's defection to Liu Zhang was not improvised, nor was they threatened by Liu Zhang. In fact, they had long wanted to get out of the Yuan family's control. However, the Yuan family's power in Dahan was too great, and it was not something that the two businessmen could get rid of. Now that Liu Zhang has given them a chance, they naturally won't miss it.

The Yuan family is like this, relying on the family background of the fourth and third dukes, and never takes others in their eyes. If it is useful, it will be pulled down, and if it is useless, it will be kicked away. They are like an uncrowned king, and it seems that others should honor them, and if they oppose their opinions, they should be disposed of. But they never wanted to think about it, why did others let them be so at the mercy of it, could it be that the Yuan family was the fourth and third dukes? Joke!

Now that Su Shuang and Zhang Shiping have surrendered, Liu Zhang is no longer polite to them, he looked at the two and asked, "In this case, I will give you a test first!" I need some good iron now to build weapons for my brothers, what kind of iron do you think is suitable for these peerless generals under my command? ”

Su Shuang and Zhang Shiping glanced at each other, they knew that it was time to show sincerity, Zhang Shiping smiled and said: "If the lord wants to give weapons to the soldiers, fine iron is enough!" Now if you want to fight the generals, then naturally you have to use betel iron and meteoric iron. To tell you the truth, Su and I still have tens of thousands of catties of betel iron and nearly 1,000 catties of meteorite iron in our hands, I don't know if it is enough for the lord's needs, if it is not enough, I can also find my peers to collect some points. But what about the price..."

Zhang Shiping was a little embarrassed, he knew that Liu Zhang would never ask for their things in vain, but he was still a little worried, and the businessman's cautious eyes were vividly displayed at this time. Liu Zhang smiled: "As I said just now, for you businessmen, loyalty is something that cannot be forced. I have nearly 200,000 sheep, 150,000 cattle, and 1230,000 horses! I can't give you horses, but I can leave the cattle and sheep to you!" ”

"What?" Su Shuang was shocked, although the profit of selling horses is the largest, but the profits of cattle and sheep are not small, especially cattle. In ancient times, whether it was the common people farming or hauling goods, they basically used ox carts. In the past, the special cars used by officials were mostly pulled by oxen. What really surprised Su Shuang was the number of cattle and sheep, and he asked weakly: "Lord, didn't you snatch all the cattle, sheep and horses from Wuhuan Mountain!" ”

Liu Zhang smiled and said: "I didn't grab many cattle and sheep in Wuhuan Mountain, there was not enough time at that time!" However, I exterminated seventy or eighty small Karasuma tribes in the prairie under the Wuhuan Mountain, and I robbed them all of their cattle, sheep and horses! ”

Cold! Chills! Su Shuang and Zhang Shiping suddenly froze there! They knew that Liu Zhang had beaten Karasuma very badly, and had also attacked the Karasuma Royal Court, but they would never have imagined that Liu Zhang was so ruthless that he actually exterminated seventy or eighty small Karasuma tribes. If this wasn't Liu Zhang's bragging, then Karasuma wouldn't be able to recover in at least ten years! However, thinking about the number of cattle, sheep and horses in Liu Zhang's hands, he doesn't look like he is lying!

Looking at the calm Liu Zhang, the cold sweat behind Su Shuang and Zhang Shiping flowed down, what kind of person is this, it is simply a killing god! They are glad that they know the times. God knows what will happen if they refuse to do so! Maybe what happened to the Karasuma people will be repeated in their home!

Liu Zhang's promise to protect Su Shuang and Zhang Shiping's families is a kindness to them, and the cruelty to the Karasuma people is a deterrent. Seeing that Su Shuang and Zhang Shiping, who were still a little casual, suddenly became very submissive, Liu Zhang nodded with satisfaction and said: "Now that you understand, let the family members move to the Youzhou Thorn Mansion first, and then leave the affairs of betel iron, meteorite iron, cattle, sheep and horses to you!" ”

"Yes! Lord! Su Shuang and Zhang Shiping bowed, they had been impressed by Liu Zhang, a thirteen-year-old boy. Besides, Youzhou is Liu Zhang's territory, if they still want to do business in Youzhou, they have to listen to Liu Zhang, and their nest is in Youzhou!

"That's right! You need a good blacksmith to fight weapons, do you know where there are good blacksmiths, you need to be very skilled! Liu Zhang suddenly remembered that the blacksmiths under his command were nine out of ten waste, and he couldn't help but feel a little entangled in his heart. Under this kind of craftsmanship, all the good iron is wasted on them!

"Does Big Brother need a good blacksmith?" Zhang Fei had been standing next to him pretending to be stupid, and when he heard that Liu Zhang needed a good blacksmith, he suddenly said: "There is an old blacksmith in Zhuo County, and his crafting skills are very good. The eldest brother might as well try it with him, maybe he can play a magic weapon. It's just that the old blacksmith has a strange temper and is not a good iron, so he will never make a move! ”

Zhang Shiping laughed and said: "The iron we dedicate to the lord is not good iron?" ”

"Lord, among the gifts I brought, there are hundreds of catties of betel iron, I will let my subordinates show you, as for the meteoric iron, the quality is better than these betel iron!" Su Shuang said with a smile: "Although the lord said that he didn't want anything from his subordinates, if he didn't offer something as a subordinate, wouldn't it be against the essence of our businessmen." So Shiping and I decided that our thousand catties of meteorite iron will be dedicated to the lord! ”

Looking at the smiles of Su Shuang and Zhang Shiping, Liu Zhang knew that they were betting! Historically, they funded Liu Bei, isn't it an alternative betting? However, although Liu Zhang wanted the meteorite in their hands very much, he didn't like their betting behavior. Liu Zhang said coldly: "Two, I know that the family always throws the children of the family under different princes, but I hope that you will only be loyal to me!" If I find out that you are funding people everywhere, no matter who you are sponsoring, don't blame me for being unkind! I don't care about what was funded before, but I must not have it in the future! ”

Zhang Shiping and Su Shuang's faces changed, they did have such a mind, and they did it. But now Liu Zhang doesn't allow them to do this, they have to make a choice. Su Shuang and Zhang Shiping thought for a while and said, "Lord, we understand!" ”

Liu Zhang nodded, since he was ready to fight for world domination, those princes would be his enemies. Liu Zhang naturally couldn't tolerate the behavior of the enemy, especially the businessmen under him like Su Shuang and Zhang Shiping. In fact, Liu Zhang is still more optimistic about the Xuzhou Mi family and the Jizhou Zhen family, but these two families belong to the top few merchant families in Dahan, and they are not under Liu Zhang's command.

After Su Shuang and Zhang Shiping announced their surrender, they left Jixian County, and they had to go to Zhuo County to bring their families. The Yuan family has protégés all over the world, who knows if there will be people who will be unfavorable to their families in order to please the Yuan family! Half a month later, Zhang Shiping and Su Shuang returned to Jixian County, and they came with the old blacksmith family of Zhuo County. Of course, it didn't take much effort for them to invite the old blacksmith to come, but as soon as they put a piece of meteorite iron in front of the old blacksmith, the old blacksmith's eyes could not be pulled out. When Su Shuang told him that he still had a thousand catties of meteoric iron and 10,000 catties of betel iron in his hand, the old blacksmith almost signed a deed of sale. However, now it's almost like selling out!

After dealing with Su Shuang and Zhang Shiping's families, Liu Zhang allocated a large part of the cattle and sheep to them for sale. After getting so many cattle and sheep, Su Shuang and Zhang Shiping didn't dare to delay and set off immediately. As for how to make a move, that's their business, Liu Zhang doesn't want to care, and Liu Zhang is looking for them to help him make money, and it's not good to manage too much!

After sending Su and Zhang away, the old blacksmith immediately found Liu Zhang. He didn't have much interest in who Liu Zhang was, but he itched from the bottom of his heart to those betel irons, meteorite irons, and refined irons. After coming for a few days, Liu Zhang has been arranging their food and lodging, but he has not explained what he wants them to do, and the old blacksmith's heart is like a kitten's paw scratching!

Knowing the old blacksmith's intention, Liu Zhang couldn't help but wonder. There is never a shortage of people with a spirit of research in this world, and the old blacksmith is one of them. Liu Zhang admires this kind of person from the bottom of his heart, because he has supreme spirit and perseverance. In the end, Liu Zhang decided to hand over all the weapons in his hand to the old blacksmith to be responsible, and the old blacksmith was grateful for his kindness, which made him a little embarrassed. However, the old blacksmith was a little lonely after the excitement. It turned out that with the ability of the old blacksmith, he could not completely melt the meteoric iron, and using betel iron to forge it was already his limit!

As a modern person, Liu Zhang doesn't know how to strike iron, but he has never eaten pork, can he still see a pig run? After studying with the old blacksmith for a long time, Liu Zhang found that the smelting technology of the Han Dynasty was still in the stage of melting iron ore, casting molds, forging and quenching. The more thoroughly the iron ore is melted, the better the quality of the iron obtained, and possibly even the steel. However, this steel is only a little harder than ordinary iron, but it is very crisp, and it cannot be compared with the steel of later generations.

After carefully understanding the process of melting iron ore, Liu Zhang finally understood why the old blacksmith could not completely melt iron ore. In later generations, coke or something needed to be added when smelting iron, but ironmaking in the Han Dynasty was still using wood to provide heat, which certainly could not fully melt the iron ore, and stones with high iron content such as meteorite iron were more difficult to melt.

If you find the crux of the problem, there is a solution, what is the steel copying method, the steel clamping method, and the steel wrapping method, Liu Zhang really doesn't understand, but it is still very easy for him to increase the furnace temperature, just change the fuel. Ancient people didn't know the role of coal, but Liu Zhang did. Youzhou is close to Mongolia, and the Great Khing'an Mountains are in this area, so it is too easy to find some open-pit coal mines!

With coal, as long as it is done properly, steelmaking is not a problem, let alone ironmaking? The old blacksmith tried to melt the fine iron sent by Su Shuang with coal, but he didn't expect that the knife he shot out would reach the strength of a thirty steel-making knife, which made the old blacksmith very excited. almost worshiped Liu Zhang as a god.

After solving the problem of furnace temperature, just leave the following things to the old blacksmith. If Liu Zhang really wants to make steel, he doesn't understand. A layman leads an insider, no matter what profession is a taboo. Of course, Liu Zhang was not idle, he drew the Zhangba snake spear, the Canyin gentian spear, the Qinglong Yanyue knife, and the tiger Benfang Heavenly Halberd in his memory with paper and pen, and only waited for the old blacksmith to become familiar with the use of coal, and began to forge these divine weapons, which once again surprised the old blacksmith!
