"Rumble!"

The Qin army marched in, like an angry dragon, rolling eastward, unstoppable.

Qin Jun's face was full of joy, and his eyes were shining, looking at them like that, where was going to the battlefield, as if they were going to a banquet.

When it comes to war, the six countries of Shandong complain bitterly, no one wants to go to the battlefield, only the Qin people "are happy when they hear the war", and regard the war as a happy event such as drinking wine and eating meat, and the expression of the Qin army is the best interpretation.

"Last year, after the Battle of Changping, Daqin was about to destroy Zhao, but there was a shortage of food and grass, and he could not support a big war, so he had to retreat. At that time, when I mentioned retiring from the army, I felt uncomfortable, and I really wanted to scold my mother. ”

"Great Qin has one enemy and six enemies, and after a hundred years of war, he has not been able to destroy a warring state, but he has to withdraw from the army at the present time, who feels better? Fortunately, this year we have embarked on a journey again, to complete the important task that we failed to complete last year! Zhao Guo, this time you must be destroyed! Must be extinguished! ”

The Qin army kept talking about it during the march, proud of destroying Zhao, proud of participating in this battle, everyone was uplifted and morale was high.

Wang Ling's helmet was pierced, mighty and extraordinary, riding a high-headed horse, standing beside the horse road, listening to the discussion of the Qin army, he was very happy, and said with a smile: "Order, advance with great fanfare, the bigger the movement, the better, well, just make the movement of the 400,000 army." ”

"You, you, you, this is a bluff, take the lead!" Huan Qi, who was next to the tomb of King Ma, laughed loudly, very cheerfully, and said: "After the Changping War, Zhao Gou broke his courage, and your movement of making an army of 400,000 did not scare Zhao Gou's courage?" ”

Wang Ling is known as the "eagle-eyed fox heart", which means that he has the keen observation of an eagle and the cunning scheming of a fox.

"Hey, hey!" Wang Ling smiled very treacherously, like an old fox, and said: "Not only do I have to make such a big movement on the road, but when I get to the city of Handan, I will also set up a big camp, a big camp of 400,000 troops." What do you think Zhao Dan thinks? ”

"Zhao Dan will definitely pee his crotch!" Huan Qi smiled very happily.

Handan, Qin Yiren's Mansion.

"I've seen Childe." Mrs. Xu saluted Qin Yiren.

"Master, please be seated." Qin Yiren was busy greeting.

Qin Yiren didn't get along with Madame Xu for a long time, but he was full of praise for Madame Xu's professionalism, Madame Xu was worthy of being a famous sword-casting master in the Warring States Period, and his attainments in sword-casting were shocking. Admirable. Qin Yiren was extremely respectful to him.

"Childe, what kind of steelmaking method are you talking about?" Mrs. Xu is a technical "madman", and she is focused on technology.

"I'll tell you this." Qin Yiren shook his head helplessly, when he met such a technical maniac, he really didn't know if it was a good thing or a bad thing, talking to him, he would definitely talk about technology within three sentences.

It seems that apart from technology, Mrs. Xu has no other hobbies.

"Perhaps, that's why he's become a swordsmith." Mastery is because of focus. Mrs. Xu is so focused, and she devotes her heart to sword forging, which may be the reason why he can become a famous sword forging master, Qin Yiren thought to himself.

What Qin Yiren said to Mrs. Xu was the "steel filling method", which is to melt high-quality iron ore into molten pig iron and cast it on wrought iron. Wrought iron is thus carburized and becomes steel. After melting, it becomes steel.

This steelmaking method was a technology that emerged during the Northern and Southern Dynasties, and was a milestone in the history of Chinese steel, and since then, steel has appeared in large quantities, and China's steel production far exceeds that of other great empires of the same period. It is precisely because of the large amount of stainless steel. In the Tang Dynasty, a luxurious weapon "Mo Dao" appeared, which equipped the Tang army in large quantities, which made the Tang army's combat power unprecedentedly improved.

During the Warring States period, the way to obtain stainless steel was to temper it a thousand times. Hammer after hammer to forge the steel to get the steel you need. This method is too inefficient, time-consuming and labor-intensive, and greatly restricts the use of iron weapons.

In the Han Dynasty, the method of frying steel was invented, and although great progress was made, it still limited the production of steel. It was not until the invention of the steel filling method that the problem of steel production was fundamentally solved.

If this technology is to be promoted in the Warring States Period, two main improvements must be made: first, charcoal can no longer be used as fuel, but coal; The second is to use a blast furnace.

Qin Yiren just saw it on the Internet, and he didn't know the specific technical details, but with Mrs. Xu's skills, of course he could solve these problems, which was the reason why Qin Yiren spent a lot of effort to keep Mrs. Xu.

It is conceivable that once Madame Xu masters this technique, the consequences will be needless to say, and will greatly promote the pace of Chinese history. If nothing else, the spread of iron farming tools to the whole country will greatly increase grain production and feed countless people, and this alone is immeasurable merit.

If the Qin army is fully equipped with iron weapons, then the combat power of the Qin army will be doubled, who dares to take the lead?

"Great! That's great! In the process of Qin Yiren's explanation, Mrs. Xu didn't know how much she said, "Great", her face was full of flames, her eyes were full of wonderful little stars, and the whole person trembled with excitement.

For a technology maniac like Mrs. Xu, it is his biggest dream to know about new technologies, and at first glance, can he not be excited?

"Master, you say, can you do such a technique alone?" Qin Yiren asked with a smile.

"Can't! Never! Mrs. Xu shook her head fiercely and said, "Childe is right, if you want to use this method, you must have the support of a great warring state." ”

The steel filling method requires a lot of manpower and material resources, and it consumes a lot of iron ore and coal, which is far from being accomplished by a private person like Mrs. Xu.

"Yiyang Tieshan Iron is obtained by Daqin, if you want to refine steel, you have to go to Daqin." Qin Yiren smiled very happily, like a cunning fox.

He spent so much effort, didn't he just want to get Mrs. Xu to the Qin State?

At that time, Yiyang Iron Mountain was the largest iron mine, the world's top ten iron soldiers ** from Yiyang Iron Mountain, Yiyang Iron Mountain was in the hands of Qin, Mrs. Xu wanted high-quality iron ore, she had to go to Qin. Because, iron ore is too expensive, not much worse than gold, it is a strictly controlled substance, and I don't want to get it if I don't go to Qin.

"Don't worry, Childe, I'll leave for the Qin Kingdom." Mrs. Xu was overjoyed and said, "I think, when I arrive in the Qin Kingdom, the King of Qin will definitely give me iron ore." ”

With Mrs. Xu's identity and fame, he will definitely cause a sensation when he arrives in the Qin State. King Qin Zhao will definitely value him, and King Qin Zhao will give him whatever he wants.

Mrs. Xu, a famous sword-forging master in the Warring States Period, countless people, many of whom were princes, wanted to get him. I want him to serve. And not available. But he was fooled by Qin Yiren and went to Qin State happily.

"Great!" Seeing Mrs. Xu away, Qin Yiren still couldn't help but feel a burst of joy and waved his fist.

Mrs. Xu's entry into Qin is of great significance, which will greatly promote the development of China's iron and steel, which is related to the national economy and people's livelihood and has a far-reaching impact. Qin Yiren fooled Mrs. Xu to the Qin State, no matter how much praise is overstated.

"Childe. What rejoices? At this moment, Huang Shigong strode over.

"Do you have a problem?" Qin Yiren asked.

"Childe, come into the house and say." Huang Shigong looked left and right.

With Qin Yiren's understanding of him, whenever there is a major event, Huang Shigong must be extremely cautious and return to the house immediately. Poured tea for Huang Shigong and said with a smile: "I can talk about it now." ”

"The State of Qin has sent troops to attack Zhao." Huang Shigong's face was solemn, and he said in a deep voice.

"Ahh Although Qin Yiren had long known that the Qin State would definitely send troops to attack Zhao in the autumn of this year, when he learned the news, he was still surprised: "When did you send troops?" ”

"Three days ago." Huang Shigong raised his eyebrows, like a sharp sword out of the sheath, and said, "Now." The Qin army is heading towards Handan, and it will arrive in Handan in a few days. ”

Leaning towards Qin Yiren, he lowered his voice and said, "Childe." Your chance to make a contribution has come. ”

Qin Yiren resisted the king's order and did not return to Qin, just waiting for the opportunity to make contributions. If Qin Yiren wants to ascend to the throne of the King of Qin, it is not enough to be famous, but also need meritorious service, and take advantage of the good opportunity of the Qin army to attack Zhao to establish great achievements, which is of great benefit to Qin Yiren.

"Who's the general?" Qin Yiren asked.

"It's the royal tomb." Huang Shigong said with a smile: "Bai Qi's old illness has relapsed, and he can't lead the army to fight. Because of this, King Qin was furious. ”

Qin Yiren had long known about Bai Qi's disobedience, and he was not surprised at all: "Although history has deviations, it has not deviated too far. Well, it's time for Xinlingjun to 'steal talismans to save Zhao', Xinlingjun is going to rise in this battle and become the head of the four princes of the Warring States in one fell swoop, I have to keep an eye on him. ”

The reason why Xinlingjun was able to become the head of the "Four Princes of the Warring States" and be praised by future generations is that he seized the opportunity of King Qin Zhao's mistakes in his later years and defeated the Qin army several times. The first time he came to prominence was in the upcoming Battle of Handan, where he killed Jin Cong, captured the Wei army, and sent Wei soldiers to kill, taking the Qin army by surprise.

"The Qin army is about to besiege the city, and the news is difficult to reach, I will, the secret soldiers will be transferred immediately." Qin Yiren raised his eyebrows and groaned.

"That's what I mean, too." Huangshi Gongda agreed.

By now, the secret soldiers have been formed and can be officially put into use.

"Yao Jia is originally from Wei, he is familiar with Wei, I will, let Yao Jia go to Wei." Qin Yiren said his thoughts and said, "Go to the Chu State and keep an eye on the Chu State." ”

In the upcoming war, the reason why the Qin army failed was that Xinling Jun seized the Wei army, and suddenly killed, caught the Qin army by surprise, and it was too necessary to keep an eye on the Wei state.

As for the state of Chu, because it is the largest warring state, it is strong, and it is a mortal enemy with the state of Qin. If the Wei army is killed, the state of Chu is likely to raise troops, and the state of Chu will inevitably be targeted.

"Huh! Childe and I have a piece of thought. Huang Shigong smiled: "I told the two of them, they are already preparing. ”

"People from Handan, keep an eye on Xinlingjun for me." Qin Yiren knew very well that the reason why the Qin State failed was because of Xinling Jun, and he must keep an eye on this person.

"Why are you staring at Xinlingjun?" Of course, Huang Shigong did not understand the harm caused by General Xinling Junji to the Qin State, and he was greatly surprised.

"How can there be so many words, tell you to stare at it. Even the number of times he climbed a woman's belly, I want to know. Qin Yiren said in a deep voice.

"Childe can do whatever he says." Although Huang Shigong couldn't figure out the reason, out of trust in Qin Yiren, he still received the order.

"Not good!"

Suddenly, Qin Yiren slapped his forehead, jumped up, and hurriedly said: "Quick, pen and ink." ”

Grabbed the pen, wrote it on parchment, sealed it with a copper tube, handed it to Huang Shigong, and said: "This letter should be sent to Prime Minister Fan Sui as soon as possible, remember to remember." ”

"Why?" Huang Shigong couldn't figure it out.

"Bai Qi, I hope I can save you." Qin Yiren secretly said in his heart.
