In fact, Liu Chan is interested in making certain improvements to steelmaking technology, and the basis for improvement is the steel filling method, which appeared in the Jin Dynasty, which can be said to be less than a hundred years different from the current historical time.

The second is that the steel filling method itself is characterized by high carbon content, which is very suitable for refining blades, and the cost is low, and the procedure is far less troublesome than 100 steelmaking, compared with the low yield of 100 steel metals, only suitable for a series of precious ornaments such as swords and swords, and the steel filling method is undoubtedly much better.

"Not only that, but you can also try frying the pig iron first and heating it with the pig iron." Liu Chan suggested with a smile.

Hearing this, Zhang Yi murmured softly: "Pig iron and wrought iron are heated together...... But the two have different melting points, so isn't it??? "Wait! The melting point of the two is different, the reason for the melting point, for a while, Zhang Yi seemed to think of a point that he had not discovered before, and at this time he only felt that he was not far from a truth, and at the same time not far from a more wonderful steelmaking method.

History is like this, in fact, there is no shortage of well-educated people in each time period, advanced technology appears in future generations, not that the IQ of the ancestors is not as good as that of future generations, but because there is no discovery of an important factor hidden in life, after a long time, it is natural to be able to discover, just to see who is lucky, happen to be able to find it, and Liu Chan himself is a later generation, some things have long been known and this is his advantage.

Just as pig iron has a low melting point, so does its carbon content, but who would have thought of mixing it with wrought iron with its low melting point? Liu Chan just reminded him that with Zhang Yi's talent, he already understood the true meaning.

Due to the low melting point of pig iron, it is easy to melt, and after the pig iron is melted, it is "poured" into the wrought iron, which carburizes the wrought iron to obtain steel. In this way, as long as the proportion of raw wrought iron is matched, the carbon content level in the steel can be controlled more accurately, and then after repeated forging, the steel with uniform texture can be obtained.

This method is relatively easy to master, and the work efficiency is greatly improved, so it has become the main steelmaking method after the Northern and Southern Dynasties. Steel-filling technology has been quite popular in the Northern and Southern Dynasties, this method was gradually developed in the practice of frying steel, and it is not so difficult to accept now, and Liu Chan's original intention is to make this advanced steelmaking technology appear a hundred years earlier than history.

Looking at Zhang Yi who was about to move and wanted to try it immediately, Liu Chan couldn't help but chuckle, this Zhang Yi was also an anxious person.

After all, Liu Chan likes Zhang Yi even more, only with his own enthusiasm can he really do a good job, so that he can really rest assured, and then Liu Chan once again told Zhang Yi all the knowledge he knew and understood about the steel filling method.

An hour later, Liu Chan and his entourage left the smelter, went out of the city, and marched towards the dragoon barracks. In Liu Chan's opinion, he has "pointed" enough, even if he is not a professional in this area, if Zhang Yi is still unable to improve the steel filling method, then Liu Chan may really want to check Zhang Yi's own ability, for people who are not capable and unworthy of the name, Liu Chan has no time to deal with more, just let him get out.

In the barracks, the training of dragoons has been resumed, and with the men and horses in Hanzhong County taking over Yangping Pass, the 4,000 people who survived the first battle in Yangping have also returned one after another.

As for the people in Zhao Yun's department, they were naturally also detained by Liu Chan, and they were all Han soldiers and a family! Now that it's messed up, I can't tell you and mine anymore, so I just formed an army, after all, I have experienced a big war like Yangpingguan, and I have some feelings.

As the other party, Zhao Yun could only smile silently, His Majesty wants someone, can he not give it? That's it, the war in the south has not been settled, the great cause of Xinghan has not been completed, and Shuzhong will still have to recruit troops in the next step, and it will be good to reorganize a group of people and horses at that time, as for their original brothers, since they can be favored by His Majesty, it can be regarded as their luck, fortunately, they are all in Chengdu, and they are not unseen all year round.

In an accurate sense, this is the third time Liu Chan has come to the dragoon barracks, the first time is when he has just transferred 3,000 people from the forbidden army to come here for a new style of training, the second time is the arrival of Chen Zhi's Bai Yu soldiers, the two armies are reorganized, and now the third time I came, I saw the forbidden army that had experienced the baptism of war, and there were still some fresh faces, those were the former Zhao Yun's department, or the original Yangping garrison.

For Liu Chan, they only respect it on the surface, but they don't recognize it so much in their hearts, after all, they know how Liu Chan performed in the first battle of Yangping.

It doesn't matter what they think at this time, Liu Chan doesn't care, Liu Chan came to reward the three armies this time, as the so-called meritorious service will be rewarded, and mistakes will be punished, and nothing can be done to chill the hearts of the soldiers, at least to mingle with the soldiers and get their approval, and a great man in later generations said that the gun will come out of power.

In Liu Chan's view, if you want to deal with the relationship with the soldiers, there are nothing more than two things, one is righteousness, and some of the generals' own charm, such as Zhao Yun, his loyalty, his integrity, his attitude towards the soldiers, do not oppress, do not scold.

Second, it is the interests, the world is bustling, all for profit; The world is crowded, all for profit. Although the problem solved with money is not the best, it is indeed the fastest effect, as for relying on its own charm to make the dragoon army obey, it is obviously impossible for Liu Chan, then use the second plan, interests, it doesn't matter if you don't want to, I'll give you a gift, and you won't hit me in the face if you give money.

"Didn't you eat? Hurry up! Hurry up! Believe it or not, Lao Tzu will suck you to death! ”

As soon as he entered the barracks, Liu Chan heard a loud voice shouting and shouting. Turning his head to look, that block, Liu Chan recognized at a glance that it was Wang Shuang, the head of the martial arts test, originally Liu Chan wanted to make him report with him today, who knew that this product was so positive, and he came early a few days ago.

"Call him here." Liu Chan pointed to Wang Shuangdao, who was too active.

I saw a soldier running over, passing a few words on his side, and then saw Wang Shuang turn around and glance in the direction of Liu Chan, and immediately straightened his clothes and armor, and hurriedly ran over.

"The last general will see Your Majesty!"

Glancing at Wang Shuang, who was kneeling on the ground, Liu Chan did not let him get up immediately, but asked, "You came two days earlier, what position are you in charge of now?" How do you feel about dragooning? ”

"Back to Your Majesty, the last general is currently in charge of the training of a team of 300 people, and the overall quality of the Dragoon Forbidden Army is not bad, not inferior to the Great Wei Tiger Army!"

"Just don't lose......

Wang Shuang knew that saying this would make Liu Chan unhappy, and then explained: "Your Majesty, there are indeed many people among the dragoons whose strength is comparable to that of the Tiger Ben Army, and even worse, but there are also some people whose level is far behind. ”

"So you're beating and scolding the sergeant? Wanton punishment? Liu Chan's tone was a little serious, hearing this, as long as he was not a fool, he could hear that the rhythm was a little wrong, and Liu Chan was a little angry.

"Your Majesty, the last general doesn't want to, but some people are just too stupid, if they don't whip them, they won't know how to grow!" Wang Shuang's face was embarrassed.

"Presumptuous! I tell you that in my Shu, it is strictly forbidden to beat and scold the sergeant, this time I read that you are a first-time offender, I will spare you, do not punish severely, if there is a next time, I will never spare you, go over and apologize to them! ”
