Outside Handan City, under Handan Mountain, in the secret courtyard of Qin Yiren.

More than 100 guards were training hard, sweating like rain, but no one complained of being tired. They are all slaves, Qin Yiren got rid of their slavery and let them become Chinese people, this is a great kindness, they are willing to die for Qin Yiren, just train, endure a little hardship, suffer a little tired, what is it?

After this period of training, these guards are very different, they are no longer the scrawny as they used to be, they are strong, like bulls, and extremely fierce.

In order to train these guards, Qin Yiren spared no expense, trained according to the standards of the Iron Eagle Warriors, and soaked them in the potion prepared by Bian Que's relict prescription every day, which cost a lot of money. If they hadn't made such progress, it would be too sorry for Qin Yiren.

After this period of training, these guards are still far from the standard of the Iron Eagle Swordsman, but they can already be regarded as elites, and the distance from the Iron Eagle Swordsman is not too far, as long as they pass a little later, they are likely to reach the standard of the Iron Eagle Swordsman.

If there are more than a hundred Iron Eagle Swordsmen in hand, Qin Yiren's strength will skyrocket, and this benefit does not need to be said.

"Oooo

A dense sound of metal crashing came from the house, and Mrs. Xu was seen holding a hammer in her hand, smashing a piece of stainless steel. Qin Yiren was helping him, the two cooperated closely, and they were very skilled, and at a glance, it was clear that it was not the first time they had cooperated.

That's right, since Mrs. Xu came to see Qin Yiren, Qin Yiren said that she wanted to ask Mrs. Xu to build weapons, but Mrs. Xu didn't say a word and agreed.

So, Qin Yiren and Mrs. Xu came here and began to build weapons.

By making steel from coal, you can get stainless steel, and you can make sharp weapons. However, Qin Yiren would definitely not be satisfied, because he also knew a quenching technique that could be used to try it. If successful, the weapon will be even sharper.

In the Warring States period. Our ancestors were using quenching technology, but the quenching liquid used was water, and its effect could not satisfy Qin Yiren. Qin Yiren decided to use animal urine and animal fat for quenching, which was a quenching technique invented by the famous craftsman Qi Wuhuaiwen during the Northern and Southern Dynasties. Dramatically improves the performance of the weapon.

Using animal urine and animal fat for quenching is not very complicated. Moreover, the conditions of the Warring States Period are also available, and with a sword-casting master like Mrs. Xu, it is not difficult to master this technique.

Qin Yiren saw it on the Internet by accident, and he didn't understand the specific operation. After a few days of exploration with Mrs. Xu, I became more and more proficient and had mastered this quenching technique.

With the cooperation of the two, they continued to forge, and the steel was beaten into a sword embryo. Then make it into a sword. Mrs. Xu's sword-forging skills are very good, every hammer is moderate, and he was born for swords.

After some forging, it was finally built, and it was time to quench. Mrs. Xu clamped the sword body with iron tongs and put it in the animal's urine, making a sizzling sound and black smoke rising. A foul smell of urine came to my nose and made people sick.

Seeing that it was almost over, Mrs. Xu put the sword body in the animal fat, and there was another sizzling sound, and there was a large cloud of smoke. But it is fragrant and appetizing.

The quenching technology invented by Qi Wuhuaiwen is two quenching, first using animal urine for quick cooling to improve the hardness of the weapon; Then slow cool with animal fat. Increases the toughness of weapons. After two quenchings, both the hardness of the weapon was increased. It also improves resilience, and it is a huge step forward in the history of Chinese steel.

Until the quenching was completed, Mrs. Xu looked at the sword body, was very satisfied, and nodded in praise: "Childe is really amazing, after such quenching, this sword is extraordinary." ”

"It's nothing." Qin Yiren waved his hand and said, "There is still a way to increase the output of stainless steel and make it better." ”

"Really?" Mrs. Xu's eyes widened, and a pair of big hands grabbed Qin Yiren's shoulders and shook them desperately: "Childe, you didn't lie to me?" ”

Mrs. Xu's strength is not small, grabbing Qin Yiren's shoulders like iron tongs, it is also the current Qin Yiren's skill, and her strength is not small. If it was Qin Yiren in the past, he would have fallen apart a long time ago.

Qin Yiren flicked Mrs. Xu's wrist, Mrs. Xu had to let go, Qin Yiren nodded heavily, and said, "Of course." However, this method is troublesome, and it is not something that you, Mrs. Xu, can accomplish. ”

"How do you do that?" Mrs. Xu asked hurriedly.

"It takes a nation to do that." Qin Yiren said in a seductive tone: "If Mr. is willing to enter Qin, I will definitely tell you about this method......

"I'm in Qin, I'm in Qin." Mrs. Xu didn't think about it, and her head slammed into it, like a chicken pecking rice.

"Great!" Meng Zhao, Ma Gai, and Fan Tong, who had been stretching their necks and staring at the sword, were overjoyed.

Mrs. Xu is a famous sword-forging master, famous all over the world, which of the seven warring states does not want to invite him? Even King Qin Zhao sent an invitation, but Mrs. Xu did not go to Qin. Now, Qin Yiren has successfully fooled Mrs. Xu to the Qin State, can they not be happy?

“…… This method is really a bit troublesome, so I'll tell you when I have time. "Qin Yiren has put so much effort into it, he will definitely not be satisfied with building weapons and equipment for the guards, he wants to firmly grasp Madam Xu in his hands and ask him to serve the Qin State.

If you get the help of Madame Xu, a famous sword-forging master, and the steelmaking technology that Qin Yiren knows, the two complement each other, and it will not be possible if the Qin State is not stronger.

Of course, Qin Yiren didn't tell a lie, he saw the technology of the "steel filling method" on the Internet, although he didn't know the specifics, he only knew a rough idea, which definitely had an unexpected effect on a big expert like Mrs. Xu, which was tantamount to the effect of a lighthouse on a ship.

The next thing is simple, Mrs. Xu put on the hilt of the sword, sharpened it, and sharpened it, and a bright sword appeared in front of Qin Yiren, the sword body was cold and shining, and at a glance, she knew that it was a good sword.

"Good sword! Good sword! Qin Yiren praised loudly.

"Goo!" Meng Zhao, Ma Gai, Fan Tong and Lu Jujian had their eyes sunk into the sword, and they couldn't pull it out anymore, their necks stretched out, and saliva flowed down the corners of their mouths.

For these warriors, weapons are their lives, and at first glance they can not be excited when they see such a good sword? Look at them like that, and I want to take them for myself.

"Try it!" Meng Zhao's eyes lit up, he pulled out the sword at his waist and stretched it out in front of Mrs. Xu.

With a flick of Mrs. Xu's wrist, a dazzling sword light suddenly appeared, slashing at the sword in Meng Zhao's hand, and in the crisp sound of metal impact, the sword in Meng Zhao's hand broke into two.

"Good! Pick! A cheer rang out, and Qin Yiren was excited.

The sword in Meng Zhao's hand was built by Qin Yiren at a great price and by good craftsmen, and it was extremely sophisticated, but it was still too far from the sword created by Mrs. Xu.

"Childe, my sword is broken, and this sword belongs to me." Meng Zhao didn't care whether Qin Yiren agreed or not, rushed up, snatched it from Mrs. Xu's hand, and ran away as if flying.

"No! No way! It's mine! Ma Gai, Fan Tong and Lu Jujian were not convinced, as if they had been beaten with chicken blood, and chased after them.

Who wouldn't want to have such a sharp weapon?

"What's there to fight about? This first sword is a test hand, and the later one is called a sharp weapon. Qin Yiren shook his head violently.

As Qin Yiren said, this first sword is good, but it is the result of Mrs. Xu's trial, and it is not very good. As Mrs. Xu became more and more proficient in steel and quenching techniques, the swords she created became better and better, and Qin Yiren, Ma Gai, Fan Tong and Lu Jujian each had one, and everyone was satisfied.

Until Mrs. Xu completely mastered it, Qin Yiren would no longer have to do anything, and Mrs. Xu would not do it herself, but instructed his disciples and asked them to forge swords.

In this way, Qin Yiren will have nothing to do.

"By the way, I forgot one thing, I still owe Huang Shigong tens of thousands of gold, I have to make it up for him." The importance of the secret soldier does not need to be said, Qin Yiren really wanted to establish the secret soldier as soon as possible, but he was trapped by the lack of gold.

"I still owe 30,000 gold, how can I make up for it?" Qin Yiren was a little nerve-wracking.

In order to raise money, Qin Yiren has done all the tricks and extortion, and he has used all the tricks he can use, and he is still tens of thousands of dollars, and he really has no way.

At the beginning, extortion, why not be more ruthless?

Why didn't you send a big wrongdoer to the door?

"Oh, there's a way." Qin Yiren thought for a while, and finally thought of a way, ordered Meng Zhao to prepare the car and go straight to Weifeng Trading Company.

Qin Yiren's return to Weifeng Trading Company caused a sensation, and Mrs. Yu personally invited Qin Yiren in, ordered someone to serve tea, and said with a smile: "Son, why are you here?" ”

"I remember someone owing Ben Gongzi a promise." Qin Yiren held the teacup and drank tea slowly.

What Qin Yiren said meant that Madame Yu lost a bet to him, and Qin Yiren could get a glimpse of it.

"It's a shame that you are the king and grandson, you are so stingy, you still remember this." Mrs. Yu smiled, like a hundred flowers blooming, beautiful, although her face was covered with a scarf, she didn't know the scene on her face, she must have been amorous: "If Childe really wants to see my appearance, he will have to take the corresponding responsibility, Childe can think about it?" ”

"What kind of responsibility?" Qin Yiren was a little curious.

"Hmm...... Childe, tell me what you mean. Madame Jade busily diverted the topic.

"This ceremony, Mrs. made a lot of money, and my son's hands were tight, and I wanted to borrow 180,000 gold from Mrs." Qin Yiren Lion opened his mouth.

The material ceremony made Mrs. Qing famous, far overshadowing the Yidun clan, and the business became more prosperous.

"You still dare to speak." Mrs. Yu raised her eyebrows, with a smile on her face, and said, "I helped you so much, I haven't asked you for Xie Yi yet, you borrowed money from me first, you are really shameless." ”

If it weren't for Madame Yu's help, Qin Yiren would not have been able to snatch the right to hold the Timber Ceremony from Xinlingjun's hands, and there would have been no later incidents. For Lady Yu's help, Qin Yiren couldn't be too grateful.

"It's not impossible to borrow money, but, in business, if you want to borrow so much, I have to give others an explanation, what do you use as collateral?" Lady Jade shows her side as a shrewd businessman.

"Papermaking, how?" Qin Yiren held his chin with his right hand, and asked lightly.

"What? Papermaking? Madame Jade stood up violently, her eyes widening.
