After hearing Mr. Hao say this, Su Hao couldn't help but blame himself. He has since traveled through time and has shaken out a lot of modern knowledge in his mind, digging wells, repairing stoves, mining coal, burning glass... It can be said that every thing that makes everyone around him feel amazing, but when he thinks about it carefully, it seems that he really lacks some awareness of keeping commercial secrets.

Let’s talk about burning glass. Use limestone instead of sheep horns, soda ash instead of saltpeter, and use quartz sand all over the mountains and fields instead of so-called glazed stone. These are several key points to break through the bottleneck of glass production. Once this layer of window paper is pierced, it is easy for craftsmen like Hao Yizong to create cheap glass.

Glass is not very useful in society at present, mainly because it is abnormally high in price and cannot compete with porcelain. Once the cost drops and has the advantages of transparency, I believe that it will soon enter thousands of households like in later generations and become one of the most common materials. In such a large market, the profits are unimaginable. However, Su Hao, who has mastered the technical skills, did not hesitate at all and showed the secret to Hao Yizong's family.

The reason is probably due to the habits brought by Su Hao from later generations. He has always worked in the geological department and has not had many commercial cells in his mind. In his opinion, these technologies were not invented by him and should belong to the entire society. As for himself, there are so many opportunities to make money, he doesn't have to care about these at all.

Su Hao thought this way, but in Hao Yizong's mind, it was a completely different idea. As a craftsman, he knew the value of technical skills too much. How many craftsmen would rather be beheaded by the government than reveal the unique skills left by their ancestors. The reason is that these unique skills are the foundation for their entire family to survive. If they are leaked, their descendants will suffer poverty.

And this young master knew such a wonderful glass recipe. He said it without reservation in front of Hao Qing, and personally guided Hao Qing to cook a pot of high-quality glass. How trust is this in his family? If he saw this recipe and took it without telling him, can it be considered an entry? The most shameful behavior of stealing the master and learning skills in the craftsman's circle. If he gains technology in this way, his descendants will be said to be a thief.

"Uncle Hao, my nephew's recipe is also heard from the truth and is not worth much. If Uncle Hao finds it useful, just use it." Su Hao said generously.

"How can that be done?" Hao Yizong said, "If Master Su is willing to grant this skill to me, then Master Su is my mentor, and his son is Master Su's disciple. Later, I won the glass made by my Hao family workshop. I will give you 50% of it to Master Su. I wonder if Master Su agrees with such conditions?"

"No!" Su Hao refused flatly, "Uncle Hao, if you want to say this, then we have nothing to say. You can use this recipe for burning glass if you want to use it, but don't want to use it."

After saying that, Hao Yizong's face turned pale immediately. Hao Qing and Hao Tong also looked at each other, not knowing what went wrong. Su Hao said so lightly before, but when Hao Yizong offered the conditions, he turned against him. Where did he start? If it was because he thought that the conditions given by Hao Yizong were too low, it seemed a bit unreasonable. With 50% of the profit, and with respect from the teacher's courtesy, what else did Su Hao want?

Su Hao walked up to Hao Yizong, held Hao Yizong's hand with both hands, and said, "Uncle Hao, you are more than enough to be my uncle at such an age. You said I am your mentor, are you planning to save my life? You also said that Brother Hao is my disciple, and I am in love with my brothers. Are you asking me to be my grandfather?

I just got this method of burning glass by chance. It can be seen by your Uncle Hao's eyes. If you get a compliment, my nephew will be very happy. How dare you sell it for a high price? I will also talk about some conditions here. If my uncle can agree, I will present the recipe. There are other recipes after that, and I am willing to share it with my uncle."

Su Hao said something so hard that Hao Yizong felt very moved. He held Su Hao's hand and said, "Master Su is kind and righteous, I am grateful. What does the master have to do? Even if I say it, I dare not violate the slightest."

Su Hao said: "I am willing to give this recipe of glass to Brother Hao Qing as a gift for meeting. I want to ask Brother Hao to accept me, so I must not talk about the rituals of teachers, etiquette and disciples. As for Uncle Hao, I will not call me a master in the future, just ask me to change it. This is my face. Later, Hao's workshop made glass. No matter what the obtained, I don't want any money. I just want Brother Hao and Uncle Hao to help me make some things frequently."

"This..." Hao Yizong could not have imagined that the conditions proposed by Su Hao were so simple. Such good skills were given out for free. He just wanted to think that his father and son were his uncle and elder brother. This could not be considered a condition.

He looked at Hao Tong with a consulting gaze. Hao Tong stepped forward and said, "Uncle, Master Su is a lofty ambition and a mere glazed formula. He really doesn't like it. Since Master Su is willing to give it all, I think we'll accept it."

Hao Yizong then stomped his feet, as if he had made up his mind, and said to Su Hao: "It's better to obey your orders than respect and change it... I'll accept this generous gift with shamelessness. What kind of glass devices should I do after the queen? No, it's not limited to glass. But if I can do anything that I can do, I will definitely put down all my work and make it for my nephew. As for the benefits of this glass, I'll have to get at least 30%, otherwise I'll never make a piece of glass in my life."

If he didn't agree to share the money in the workshop, the old man vowed not to make glass again. Is this a threat to me? Su Hao thought with amusement and crying. He was willing to tell Hao Yizong the formula of glass without reservation, mainly because he felt that the other party had actually mastered the glass manufacturing technology, but something went wrong in some places. Seeing the old generation of craftsmen in the pit and unable to get out, he instinctively wanted to reach out and pull it.

As for rejecting Hao Yizong's previous suggestion of sharing the 55% share, he also had the idea of ​​retreating to advancing. He believed that with Hao Yizong's moral character as an old craftsman, he would never take advantage of him as a young person. Whether it was sharing the profits or helping him make something for free afterwards, he knew that he would definitely get rewards from this matter.

Sure enough, Hao Yizong was surprised to use this method to force himself to get 30% of the dividends, and if he refused, there was no need for him to refuse.

"Okay, since Uncle Hao is so persistent, then my nephew will be ashamed of it. Gu Zhiyun was given by the elders, but he was disrespectful. However, the glaze stone used to burn glaze must be provided by my nephew, and the remaining expenses and efforts will be borne by Brother Hao. What does Uncle Hao and Brother Hao think?" Su Hao said.

"You are so polite to change me." Hao Qing said happily. Hearing that his father had changed his words and called Su Hao a virtuous nephew, he naturally followed suit and called him virtuous brother.

Everyone happily said some polite words. Hao Yizong pointed to the dozens of transparent glass that had just been made and asked Su Hao: "Nephew, I just heard Qing'er say that you want to polish these glass pieces into shapes, but I don't know what to grind them into, and how to use them?"

Su Hao asked Xiao Wuzi to get a piece of paper, then picked up a charcoal strip from the pile of firewood beside him, and then painted it for Hao Yizong on the paper, explaining it while drawing:

"What I want to do is some such lenses. Each set is 4 pieces, two of which are convex, and the size and shape are like this..."

Hao Yizong is an old craftsman. When Su Hao said that, he knew what he wanted to do, and he had even figured out the specific polishing process in his mind. Hao Qing had learned his father for many years and had a good foundation. As Su Hao talked about the situation, he kept nodding, saying that he had understood and could do it according to Su Hao's requirements.

"After the convex mirror and concave mirror are polished, please place the convex mirror in front and the concave mirror behind and look into the distance. If the younger nephew expects, the uncle should clearly see the scenery in the distance through these two lenses. Then, please ask the uncle to fix the two lenses with a cylinder to form a lens barrel. A pair of lens barrels are in one place, so that both eyes can be looked at each other. In order to achieve this, the two pairs of lenses need to be polished to the same size so that the barrels on both sides can be as long as the barrels on both sides."

Su Hao told Hao Yizong according to the structure of the telescope in later generations. It is not realistic to make an anti-shè telescope now, so let's make a pair of binocular Galileo telescopes first.

"Can you clearly see the scenery in the distance?" Hao Yizong really couldn't imagine what Su Hao wanted to explain.

Su Hao didn't explain either. He believed that after Hao Yizong polished out the lens and then matched the convex mirror and the concave mirror before and after, everything would be understood. Didn't the legendary invention of the telescope accidentally discovered this phenomenon because of a mirror grinding technique?

"Don't worry, I'm starting to polish this lens now, so I will definitely not delay the nephew from being useful." Hao Yizong didn't ask much, and he agreed to Su Hao's request directly. As for wages, there is no need to mention it. Now everyone is a family.

Grinding lenses is a very troublesome thing, so Su Hao and wait for the internet naturally could not sit here and wait. After receiving Hao Qing's promise to inform him immediately as soon as he completed it, Su Hao took Hao Tong and Deng Kui to leave Hao's workshop.

Hao Qingdai's father sent the guests away, returned to the backyard, and asked his father: "Father, since Su Hao said that this recipe can be given to us for free, why do you have to give him 30% of the dividend? In the opinion of his son, it would be fine if we earn money and give him a gift. These 30% of the dividends will be passed down from generation to generation."

Hao Yizong said: "What do you know? This young person doesn't take such a precious formula seriously and can be sent in at will. It can be seen that the good things in his stomach are far more than this glass formula. We will give out three-point dividends and tie him up with us. In the future, he will take out some skills, which is not just something we can buy with this three-point dividend?"

"Father's vision is far-sighted, and his son is short-sighted." Hao Qing said suddenly with enlightenment.

Hao Yizong said: "Go and bring the oil and stones quickly. Let's take action together and grind out what Su Hao wants as soon as possible. According to what he said, this thing is also a valuable item. Let's make it and see what's going on."
