The first furnace of steel in the new laboratory was manufactured, using the famous Pei furnace steelmaking method.

This steelmaking method is very simple, that is, the pig iron is melted at high temperature in the crucible in the boiler, and the air is blown into the boiling pig iron by the blower through the clay pipe, and a large amount of heat is released due to intense oxidation, which greatly reduces the nitrogen and phosphorus content in the molten iron, so that the carbon content of the smelted iron is greatly reduced, and the hardness reaches a very high standard.

This kind of steel can be used to make legendary blades in batches, and it can be said to be an epoch-making thing that changes the battlefield mainly for cold weapons.

"Master, what can you do with these fine irons?" Wu Yuan looked at Yang Yun who was studying the steel that had been refined, and asked curiously.

Yang Yundao: "Now the output is too small, there is nothing to talk about, the next step is to expand the steelmaking furnace to prepare for the industrial production of steel...... However, it is not suitable to place the steel mill in the city, it must be placed outside the city, preferably near the river. ”

Wu Yuan frowned and said, "But...... Isn't it the elixir that Your Majesty asked the master to refine? If these things ...... was discovered by the imperial court, I am afraid that it will be difficult to explain. ”

Datang iron ware is controlled, if Yang Yun manufactures it in large quantities, in Wu Yuan's mind, it will definitely arouse the vigilance of the imperial court and bring unnecessary trouble.

"No matter how much, as long as I can produce in a relatively secret place, I don't hoard food, I don't train soldiers, just make a little fine iron, who can think that I am a rebellion?"

Yang Yun didn't want to make things public, so he kept a low profile, experimenting and producing epoch-making things one by one, and slowly changing this era.

"Yes, master."

Wu Yuan did not argue with Yang Yun and respectfully accepted the order.

Yang Yun said: "Since the refined iron has been refined, the elixir should also be refined, so as not to be gossiped about...... After all, Your Majesty is waiting for me to offer the elixir. ”

Yang Yun can now study all kinds of things at home with great fanfare, and it is precisely because Li Longji has asked for pills to come to him, since the emperor asked him to refine the pill, no one will pay attention to what he is doing.

Anyway, everything can be pushed to alchemy, saying that these refined iron are alchemy materials, and others can still jump out and refute him?

The results of the experiment are in vain, and if they are not quickly put into practice.

It's something that can bring him money, status, honor, and he's like a careerist now, trying to put everything in his head into practice.

……

……

Yang Yun was ordered to get married, and outsiders paid attention to his relationship with the Zhang and Li families, speculating which side he would lean on, but they never thought that Yang Yun would secretly conduct other research.

The person entrusted by the emperor to supervise Yang Yun's alchemy was Princess Xianyi? But after the little princess tore her face with Yang Yun, she never came again, and for the time being, Yang Yun's alchemy is wild free-range? No one interfered.

Li Longji didn't force Yang Yun to refine the pill during this time and give Yang Yun the identity of a national teacher? It is equivalent to saying that after admitting the affairs of the Tang Dynasty Taoism, it will be arranged by Yang Yun.

What Yang Yun is in charge of now can't do with the functions of the three provinces and six ministries? Therefore, it is not his turn to intervene in the affairs of the DPRK and China? But once it comes to the rise and fall of the royal family? Will Li Longji consciously ask Yang Yun? Based on Yang Yun's opinion, this is much higher than the status of the prime minister and Shangshu.

Within two days of getting married? Yang Yun didn't go back to his yard.

Through the Mi family, he rented a big house outside, so that a few little Loli around him could live more comfortably? At the same time, it is also convenient to place the slaves who have been rewarded several times before and after the palace. As for the original home, should it be occupied by the magpie's nest? Just let Zhang Yu and Li Konger live over there.

And Yang Yun's real mansion is in Chang'an.

What does he get? It is likely that Li Longji will return to Chang'an before the summer, so he will not need to buy a yard for himself in Luoyang, which is not cost-effective.

As for the previous rumors that the emperor specially repaired his house in Luoyang, at least as far as the current news is concerned, Li Longji also mentioned it, and it seems that it has not been implemented, so he is not looking forward to the surprise.

Yang Yun now put most of the money rewarded by the emperor and the money earned by the Drunken Immortal Mansion into various experiments.

Steelmaking is only one aspect, there are three acids and two alkalis, as well as looms, steam engines, etc., he wants to put the industrial revolution into practice in Datang one by one.

On the third day after marriage, Yang Yun picked up Yang Yuhuan from the palace.

At this time, the Zuixian Building was still hanging the sign of "The Owner is Happy", and it was closed, Yang Yun took Yang Yuhuan to the Zuixian Building, and asked Yang Yuhuan to have a big meal.

Yang Yuhuan was not very happy.

Yang Yun had promised her before to take her out to attend the wedding banquet, but because Yang Yun knew in advance that Li Longji would go to his house, he temporarily notified Yang Yuhuan to cancel his travel plan, so Yang Yuhuan did not witness Yang Yun getting married and starting a business, and he felt very uncomfortable.

"Shiro, you have a wife and forgot your sister, right? Seeing that you don't care about anything, my sister faces the statue of Xuannu in the palace every day, coldly, while you yourself are happy outside......"

Yang Yuhuan's face was full of grievances, her mouth was full of complaints, and her words and deeds all reminded Yang Yun that her sister was more important than the wife at home and needed more care and care.

"How could I have forgotten my sister? To tell you the truth, now I and the two young ladies in the family are not doing anything......" Yang Yun told the hidden secret in order to show his "political correctness".

"What?"

Yang Yuhuan's eyes widened in surprise and blurted out, "You...... You mean, you and the two daughters of the Zhang family and the Li family...... Don't have a cave yet? ”

"Hmm."

Yang Yun nodded heavily.

Yang Yuhuan shook his head and asked puzzledly, "How can this be?" Although you are young, you should understand everything you should understand, right? Why not a cave house? Why are you making my Yang family scatter like this? ”

Yang Yun said with a smile: "Sister, don't you want me to concentrate on taking care of you, sister, and don't just care about being happy and happy?" Now that my brother is as pure and flawless as before, why does my sister complain that my brother didn't indulge in lust? ”

Yang Yuhuan took a sip and said angrily: "You stinky brother, you will entertain your sister...... Sister and ask you, will you not deliberately not follow them because you are a member of the Dao Sect...... That's it, right? In the future, you will always devote yourself to cultivating the Tao, without distractions, and let them stay alive and widowed? ”

Yang Yun didn't want to explore this question with Yang Yuhuan, after all, there is a difference between men and women, they are sisters and brothers, but in fact, from a certain point of view, the two are just close friends, or the kind that Yang Yun intends to maintain a relationship, and it is not good to talk too much and go too deep.

"Sister, let's not talk about this, I have my own troubles, why don't we talk about my sister and Your Majesty? It seems that after my sister married into the palace, she didn't ...... with Your Majesty That's it, right? ”

Yang Yun countered Yang Yuhuan's army.

Yang Yuhuan's face suddenly became ugly when she heard this, she had no scruples about discussing other people's private affairs, but when it was her turn, she was very shy about talking about it.

"You don't have to worry about my sister's affairs, my sister entered the palace as a Xuannu Niangniang, how can she casually have those unclear relationships with mortals?"

Yang Yuhuan really regarded himself as the incarnation of the Nine Heavens Xuannu in the mortal world at this time.

Of course, Yang Yun knew why Yang Yuhuan had such confidence, which he subtly brought to Yang Yuhuan, and said cautiously: "As long as my sister is happy...... Everyone's situation is their own choice, and they will face all kinds of unpredictable consequences, my sister doesn't have to pay too much attention to my family affairs. ”

"Okay, okay, when you grow up, my sister won't talk nonsense to you much, so as not to bother you about your sister. But I want you to remember that there is only one male left in our Yang family, and I don't know how the rest of the family is now, most of them should be scattered in Shudi, right? ”

Yang Yuhuan suddenly felt a little sentimental.

Because of her bleak background, she was taken to Luoyang by her uncle after her parents suffered a catastrophe, and she has been carefully surviving in the world, and everyone in her uncle's family must be smiling, lest she be kicked out of the house, and finally came out with the help of Yang Yun, but now even the youngest Yang Yun has started a family, and she is still alone, and she can't help but think of other relatives.

Yang Yun smiled: "Why don't I write to Shu and ask the local government to help us find those lost relatives?" ”

Yang Yuhuan retracted his mind, looked at Yang Yun, and finally nodded firmly, and said: "We are considered to be famous, I am a concubine, you are the uncle of the country, or the national teacher of the Tang Dynasty, you can't let your family suffer all the time in Shudi, right?" How about bringing them in, and we can give them a little good, so that they can also live a good life? ”

Perhaps Yang Yuhuan has been sending people under the fence when he was a teenager, lonely and miserable, and seeing that he is soaring, he wants to give his family some benefits, which can not only give psychological comfort, but also have a kind of glory of returning home.

This fully satisfied the vanity in Yang Yuhuan's heart.

This is nothing to Yang Yun.

In history, Yang Yuhuan also benefited his family after gaining power, it can be said that the chicken dog ascended to heaven, and the three sisters were awarded the Mrs. Guo, and each of them spent 100,000 yuan per month to increase fat powder, and all cousins were given to high-ranking officials, even the distant brother Yang Zhao, who did not learn and did not know how to do it, was also the prime minister. The Yang family married two princesses and two county lords, and Li Longji even personally wrote the temple monument for the Yang family and the Shujia family, and was prominent for a while.

It's just that there is no such person as Yang Yun in history, maybe the clan was separated and lost after the death of his parents, and it is more likely that he died quietly in the Southern Barbarian Rebellion in Shifang, and Yang Huahua naturally would not admit that it was caused by her poor care, and she fooled her casually.

"Leave this matter to me, I will send someone to Shudi, let the Jiannan Jiedu envoy and the assassin history of each state find it on their behalf, let a few sisters know our situation, and then send a sum of money to let them come to the capital to join their relatives." Yang Yun made a promise.

Yang Yuhuan ate a few bites of food, suddenly thought of something, and said with a little sadness: "It's a pity that even if we have the ability now, we still can't take care of them too much, my noble concubine is not worthy of the name, if Your Majesty can reward some more things, I don't need you to pay for it......"

I want to benefit my family, but I don't want to pay for it myself, and I don't want Yang Yun to pay for it, in Yang Yuhuan's view, my brother's money is also my own money.

Yang Yun smiled and said, "If you just let them settle in the capital, it won't cost much, so my sister can rest assured." ”

Yang Yuhuan pursed his lips and said, "I can't let you break the bill alone, it's better for me, who is my sister, to find a way." ”

Yang Yun frowned, what kind of ghost are you going to do?

With your current ability, can you really make money?

Could it be that Yang Yuhuan wants to ask Li Longji for it?

With Li Longji's current appearance of the Nine Heavens Xuannu and Yang Yuhuan, it is not difficult to get the emperor's brother-in-law to pay for it.

It's really a good thing to just bring those people from the Yang family to the capital?

In history, these people relied on Yang Yuhuan to be favored and trusted, but they didn't make a lot of trouble.

Yang Yun didn't know other people, with the character of Yang Huahua's two people, they wouldn't stop when they arrived in the capital, thinking about it like this, it seemed that bringing them to the capital would only cause trouble.

However, since he promised Yang Yuhuan, he will still honor it.

"Sister, how did you use the things you gave you last time in the palace?" Yang Yun suddenly asked with concern.

Yang Yuhuan sighed: "Things are good, but they are flashy, and you get tired of playing for a long time, do you have anything more tangible that can kill time?" If not, send me another batch of beads, and I will use them to reward the people in the view, so that they can do things for me. ”
