Yang Xin'an also looked yearning, looked at his sister and said: "This is just the battle method of the inscription fighting technique, what do you say the fighting method of the supernatural power will be? I heard Liu Lao say that the powerful inscription fighting technique is not worse than the supernatural power." ”

Xiao Zhengtai could only look at the brother and sister with emotion and vision, he had not officially contacted cultivation yet, and he knew much less than the current brother and sister, and he couldn't answer at all.

The hard-working brother and sister didn't want to go shopping, so they hurried home to practice, and Xiao Zhengtai also began to seriously learn pile skills and qi and blood handling techniques.

In this way, the brother and sister lived between the academy and home, as well as the city lord's mansion, and after a few days, two truckloads of coal mines were finally delivered, and the brother and sister had built the furnace in the corner of the backyard in the past few days, and a warehouse was built there.

Originally, the brother and sister thought that they had to go to the housing sales center to apply for renovation, but Liu Lao happened to come out and ask the two of them before telling them that the big yard like the one they live in now can be transformed according to their own ideas, which is a privilege!

Liu Lao inquired about what the brother and sister wanted to do, when they knew that the two were ready to study how to fire glass, they were happy to participate in the research together, and his old man had seen others burn glass bottles, the process of crystal bottles, just the natural ore that has been used, the cost is relatively expensive, the firing is actually a formation, just firing a thousand will cost a few pieces of white yuan stone in the vitality, if there is a simple way, his old man is naturally willing to see.

For the positive attitude of the old man, the brother and sister are still more skeptical, Yang Xiaoxin pestered and asked several times before he knew that this old man wanted to go to the Inscription Association and the Pharmacy Association to get benefits, because the consumption of bottles made by these two companies every year is the largest, and the gold coins consumed in terms of storage capacity are counted in hundreds of millions, which is only the money at the point of container loss, and the production consumption is generally calculated in billions, which is indeed a great investment in this low-productivity world.

With the addition of Old Man Liu, making glass is much simpler, but after hearing that the two of them are actually going to make glass out of sand, they can't restrain themselves a little and want to beat the brothers and sisters, isn't this a brush for him?

Yang Xiaoxin had to explain to him: "In fact, high temperature can change the original form of many things, such as water will continue to disappear and become gas after boiling water, for example, clay can be fired into naughty porcelain, and alloys may appear in the mixing of several metals, etc." ”

The brother and sister knew that the glass was fired from sand, but what kind of sand was not very clear, and it took a little experimentation to find different types of sand, crush it into a very fine powder, and put it into a furnace to fire, through stirring and proportioning to improve the purity and transparency of the glass, it took five days to successfully make a colorless transparent transparent glass without tiny bubbles, and after the process was completely recorded, the brother and sister began to try to make some bottles and jars.

Things have been experimented, and the rest should be to decide whether to produce it yourself or let someone else produce it, in fact, this doesn't need to be thought about, one is that the strength of the brother and sister is too low, and it is estimated that the production process will soon be stolen if they produce it themselves, after all, it is unlikely that the factory will be built in the city.

The second is that Yang Xiaoxin feels that the two of them really don't have to be overly concerned about this, just let the master Yan Feihua manage it, and it is simple and easy to get a lot of net profits.

The two who were just about to do this were stopped by Liu Lao, who said that his family could cooperate with the two, and he made a guarantee to ensure that the brothers and sisters would definitely share a lot of dividends.

Looking at this old man who was competing for business with his granddaughter, the brother and sister didn't know what to say, and after thinking about it, he also had a share of the glass development, and they had been together for so long, and they had never heard of his old man's family power in Dawning City, according to the normal situation, his family should be a pretty big family.

Since the old man opened his mouth, he thought that he had already cooperated with Yan Feihua for a lot of business, and it was not bad to give up a business to Mr. Liu's family, and after signing the contract directly, Yang Xiaoxin handed over the glass production process flow chart to Mr. Liu, which was to facilitate his family's learning.

Now that the glass has been manufactured, the brother and sister are ready to replace all the windows with glass windows, and install curtains, looking at the windows on the whole house, Yang Xiaoxin muttered a little speechlessly: "This window replacement should be replaced with the window belt frame, what style of frame structure should be used?"

Five buildings, hundreds of windows, Yang Xin'an also felt that the project was a bit big! I don't know if I can replace them all, and whether it will be too incompatible and ugly after replacing them.

After taking a closer look at the window structure, he said: "It should be enough to remove all the carvings on the window and carve the frame, and there is no need to replace it as a whole, but we have to wait for the large piece of flat glass to be manufactured before trying." ”

Since it's useless to think about it now, the brother and sister began to try to make lens glass again, and are going to make some full-length mirrors, keep a few at home, and send a few to the master.

After the brother and sister framed the full-length mirror, they loaded it into the carriage and prepared to go to the master of the City Lord's Mansion to have a walk.

When she arrived at the City Lord's Mansion, she was naturally let in directly, and as soon as Yang Xiaoxin saw Yan Feihua, she took her hand and asked her to close her eyes, saying that there was a surprise for her, and Bai Xi on the side was also asked to close her eyes.

Yan Feihua is still very clear about Yang Xiaoxin's big ghosts, but she also wants to see what this surprise is, so she agreed to close her eyes.

When Yang Xiaoxin asked the two of them to open their eyes, Yang Xin'an had already placed the mirror in front of the two of them, and the one-meter-wide and two-meter-high full-length mirror completely reflected Yan Feihua's appearance, and I don't know what happened this time, Yan Feihua didn't show too surprised expression, but just posed in front of the mirror for a few times before saying: "What's the matter, the little girl wants to see my shocked appearance?"

Hearing Yan Feihua ask, Yang Xin'an hurriedly explained: "Master, this time the two of us are simply here to give gifts, and this business has been cut off. ”

Bai Xi, who was grimacing in the mirror on the side, said in surprise: "What? Who dares to rob my mother's business, I will ask my father to send someone to arrest him." ”

Yang Xiaoxin put her arm around the little junior sister's shoulders and said, "I'm afraid not, your father has to salute when he sees him, how dare you arrest him!"
