Although Yang Heng handed over the matter to Jia Zuo, it was also very lonely outside, so it was better to accompany Jia Zuo to learn a little craft here.

"Oh, this potion is like this, it can turn silver into a liquid." Yang Heng saw this scene, but he was shocked, before, when Jia Zuo was gilding the glass with silver, it was the silver liquid he brought, but now, he saw how he made the silver into silver liquid.

"Master Jia, this solution won't dissolve other items as well, right?" "No, I have two formulas, one can dissolve gold, now, I will leave this recipe to you, Alang, otherwise, I will also take it to the grave."

This guy, he is guarding a mountain of gold will not use it, but to do the most unlevel fraud, you say, you cheat to make the level of it, and even let people recognize it, but this also happens to be cheap for me, such a good formula, but the best way to extract gold and silver, and see how expensive this method will be, otherwise, he will not cheat.

"Cheng, this recipe will be made for me, but you need to continue to study these recipes, from now on, even if you are a technician of precious metal extraction, you can also take on the position of a mentor, especially, you can also have a house in the academy, as for marrying, that is your own business, however, I will be responsible for the expenses of your marriage." Since he had received such two good formulas, Yang Heng would naturally not say that he had treated him badly.

"Thank you, thank you, Alang, though. You want this recipe. Is it also preparing to make fake jewelry? "That. Yang Heng was a little stunned, what is the situation, I have asked you to make a mirror, and you are still thinking about making fake jewelry.

"I said, are you just that kind of talent, how the hell did you learn these two formulas?" "Well, I developed it myself inspired by an old way, but. He didn't make fake jewelry, but made real gold and silver fake, so that he could take the gold and silver away in the open. ”

The process of things is like this, this old way, is also a half-hung liar, he makes a living by giving people the law, but he doesn't charge money for his practice, but when he does it. But he asked the master to prepare a few gold and silver ingots as a tribute, and then. He treated the surface of these gold and silver ingots, of course, after the completion of the practice, he took it away in the open, since he was a liar, there will naturally be a time to be recognized, in the last time this old way cheated, he was seen through by the master's family, as a result, he was beaten and thrown in the wild, and then, he ran into Jia Zuo, so Jia Zuo inherited this craft, and then, Jia Zuo carried forward this craft, and directly replaced it with a solution that can dissolve gold and silver, the same, This is also a stupid person, his brain doesn't know how to be civilized, and he is actually used to cheat, but this is really embarrassing for him, gold and silver mines, but he can't get his hands on it, naturally, he doesn't want to sell formulas, so there is something that happened to be saved by the housekeeper. Since it is not an ancestral heirloom, it is not so cherished, which is cheap Yang Heng.

Jia Zuo can't touch the gold and silver mines, but Yang Heng can touch it, and in the future, he can use this chemical method to extract gold and silver, and even purify gold and silver.

However, at present, it is better to do a good job of the mirror first, you must know that once this glass mirror is developed, it is much more profitable than metallurgical silver smelting, and Yang Heng found that this Jia Zuo, in terms of technical research, is really not to say, he was able to convert a semi-finished formula into a fully finished product formula, but his luck was a little worse, and his vision was a little worse.

Jia Zuo, really didn't disappoint Yang Heng, he took a detour in the middle, but soon, he found a real way, this way is, first you need to turn the silver into silver liquid, and then attach it to the glass, and then use a curing agent to solidify the silver liquid on the surface of the glass, you know, this silver liquid is attached to the glass, not to the copper, this silver liquid is difficult to attach to the glass, but Jia Zuo, is really powerful, even after understanding how to attach it, that is, after knowing the formal procedure, A new curing agent was quickly developed, and Yang Heng found that this mirror was no less bright than the aluminized mirror in his previous life.

On this basis, Yang Heng not only asked Jia Zuo to study the matter of silver plating, but also asked him to study gold plating, what is this gold liquid for, naturally in order to increase the value of this newly appeared mirror.

There are several kinds of mirrors newly developed by Yang Heng, according to the size, the small one has a round mirror in the palm of the hand, and the large one is naturally a one-person high mirror, and this mirror is also the largest single piece of glass that the glass factory can make at this time.

If in terms of style, there are ordinary styles and luxury styles, but whether it is an ordinary style or a luxury style, the price is not low, but because the luxury style is accessorized with gold liquid, plus some exquisite frames, the price is more than ten times that of the ordinary style.

"Husband, (big brother) What have you been doing these days, why haven't you seen your people all the time?" Changle, Yu Zhang actually came to ask for the guilt in unison after Yang Heng came back.

"Lady, Yuzhang, I have made a good thing for you, you close your eyes first." Yang Heng pretended to be mysterious, "What, you still want us to close our eyes and not close them." "Well, close your eyes, I'll surprise you." For a long time, the relationship between Yang Heng and Changle Yuzhang has been quite good, that is, the previous questioning, it was also deliberate, and they also knew that Yang Heng was afraid of any rumors, so he went out to avoid suspicion, this is mainly the reason why Changle is pregnant, if she is not pregnant, then what rumors are not afraid, in fact, this is also a matter of human words, if you are really not afraid, it doesn't matter, but these things, can be avoided, it is better to avoid.

"Alright, alright, husband, you have to hurry." The two girls really closed their eyes.

"Bell, bell." Yang Heng made a strange voice while coming behind Changle, at this time, he remembered, Changle, I really can't surprise her, she is a pregnant woman, if she is frightened, then it will be bad, but this has already been said, so okay, it can only scare Yuzhang, however, Yang Heng still hugged her behind Changle's back.

"Alright, open your eyes." "Ah" Sure enough, this fright was terrible, Changle was startled when he heard Yu Zhang's voice.

It turned out that Yang Heng was holding a square mirror in front of Yu Zhang, this, what would it look like when you opened your eyes and saw a face exactly like yourself in front of you.

"Oops, it scares me to death, big brother, this is the mirror, the mirror is so clear." "What, why didn't I see a surprise, but let my little sister be frightened." "Okay, lady, it's all to blame for the husband, isn't the husband afraid that our daughter will have some accidents, so I didn't dare to give you any surprises, this is the mirror, you sisters are one side."

"Really, this mirror is so clear, no wonder my little sister is scared, this is actually made of glass." "Lady, Yuzhang, you say, how about this deal?"

"Husband, you mean, this mirror is also in mass production?" "Yes, otherwise I would ask you how to do this deal, but this deal is not something that our family can do alone, because the price may be very high, so I still want to do this deal with Your Majesty."

Before, no matter which business is not possible for a long time, and this business will not be a problem if it is done for hundreds of years, so Yang Heng will naturally not quickly reduce this thing to a low price, then, it is still necessary to really find a backer, but it is not enough to rely on his Yang family alone, Yang Heng also needs to bring in the two sisters of Changle Yuzhang, although these two are his wives, but, in Datang, the women who marry are mainly women from families with more money or rights, They all have their own inheritances, and they have them that their husbands can't get.

Therefore, although they are a family, these two people can also shelter from the wind and rain, besides, these things are not cheap for others, and then they will be either for their sons or their daughters, isn't it the same as what they gave them, Yang Heng is really kind.

And Li Er, will he make a move on his daughter, take half of each, and why doesn't Yang Heng find someone else, but in the face of this kind of huge profit, it is really not something that Yang Heng can keep. (To be continued......)
