The old lady and her aunts finally had one thing to do, that is, to sew a large sphere for Yang Heng, which turned out to be the thinnest and softest animal skin made of nitrate.

In fact, this work was not arranged by Yang Heng for the old lady to do, but the old lady took the initiative to ask for it. "Heng'er, my mother hasn't done anything all these years, and I feel like I'm going to rust, otherwise, you will sew this balloon for my mother and your aunts."

"Cheng, mother, I am more assured of your needle and thread, and when the time comes, it will be safer."

"Giggles, sister-in-law, the eldest nephew is really good at talking, in this case, the aunts just don't care to sew, don't worry, big nephew, the aunts will give you what balloon to sew for you What kind of balloon is strong, and it doesn't leak at all."

"Uncle, this is a wooden box, my requirement is that it must be made strong, at least five hundred catties of things can be placed in it without being crushed, and it must be reinforced with iron sheets in key parts, don't shake it casually and fall apart."

When Yang Heng remembered to draw a map, he remembered aerial photography, and now there is no camera, so it is also possible to locate it from the air, which made Yang Heng think that he should make a hot air balloon.

Although there is no fuel to heat and inflate the balloon, it is completely possible to choose some coal with high combustion value and fast burning as a heat source for heating and inflation, and even make a miniature steam engine to make it a power source for progress, these are completely possible to make, if the hot air balloon is successful. It's okay to do more research on airships. Especially now that hydrogen is available. Even if hydrogen is dangerous, it is entirely possible to create some non-flammable gases similar to hydrogen to fill empty boats, you know, these things, Yang Heng only needs to provide an idea, or even a research direction, and then he doesn't need to care, when will the results be produced. He will enjoy it whenever he wants.

When the old lady and the aunts sewed the balls, and even asked the maids to weave silk ropes, Yang Heng asked the uncle to hand over the manufacture of the wooden box to his subordinates, and he led the uncles and several younger brothers to start a journey to check the Yang family's industry.

"Uncles, Shuo Fang, I won't take you there, that place is not much for our family's estate, only a vineyard. There's also a brewery there. ”

Although it is said that wool, the cashmere products factory is also in charge of the new life. However, that is the industry that belongs to Changle and Yuzhang, Yang Heng doesn't want to compete with his future children for the industry, and most likely, the one who will become the dowry of Yang Heng's future daughter at that time, if Yang Heng has a daughter.

And cotton planting, the seed planting technology was handed over to the Cui family as a dowry, and later, at the time of the auction, Yang Heng directly made the decision and sold half of the cotton plantation to the Cui family, as well as the personnel, and the remaining half belonged to Li Zhi, however, it was not for Li Zhi, but it was hung in the name of Xiao Niang, and Li Zhi was in charge of it.

And really as the Yang family's industry, only vineyards and wineries were left in Shuofang, and Yang Heng also compressed the output of the winery, the output was not high, if the grape production was high in the future, they would sell raisins, or grapes.

"Uncles, as far as liquor is concerned, our family's fruit wine industry, I have already auctioned it out, but the technicians did not bring it, and now at home, only the production of high-grade liquor is left, that is, it has been brewed for thousands of years, and in the same way, the output of this thing has been reduced a lot, this, it is mainly used to make friends, not to sell."

Yang Heng's plan is that since there is already a form of auction, then, as a liquor, in the future, part of it will be used for auction, and part of it will be used to give away, taking the real high-end route, they don't rely on this wine to make money, because his family has a special recipe, so for the brewing of high-grade wine, Yang Heng also auctioned off the technology and the authorization of various places.

"Here, it's the train factory, and here, I've done the integration." It is a very earthy name, and it is not worthy of the name, it is said that it is a train manufacturing plant, in fact, it includes three parts, one part is naturally a car body manufacturing plant, one part is a steam engine and various power machinery factories, and a part is a heavy machinery manufacturing and train drive machinery factory, if you put it more concisely, it is a car body factory, a power factory, a drive reducer factory, just three parts, that is to say, a heavy machinery factory that Yang Heng just built last year was merged into this place.

This train factory is in cooperation with the royal family, and even the railways are co-made with the royal family, even the operation of the train, and then the Yang family's own industry.

"Although I also auctioned off the glass factory, I still kept this light bulb factory, especially this filament, which is a key technology, and everything else can be learned, but this can't be learned."

With the increase in glass production, the value of glass has dropped, so Yang Heng has auctioned off a lot of homes, and there will be no money-grabbing projects in the future, but Yang Heng has left the optical instrument behind, and there are not many temporary personnel, and it is still being studied.

However, the glasses, Yang Heng handed it over to those second goods, this, let them toss together, and some of the baby's industry, Yang Heng also took it back, now the baby does not need these things, however, Yang Heng still saved some money for the baby, and finally took back the things in the baby's hands, which should give her some compensation, however, the baby still has the safe shop in his hand, this sales are also good, this, Yang Heng does not plan to take it back.

In addition, Yu Zhang and Changle also handed over some things, because now the wool industry is enough for these two to toss, and they have no extra mind to take care of other things, and the accounts from Shuofang every day are enough for the two of them to be busy. That is to say, the figures of these two princesses have disappeared from Chang'an City, and they used to often come to care about their shops, but now, they have nothing to do in Chang'an City, only their respective princess mansions are in Chang'an City, yes, not long ago, Li Er also established a princess mansion for Yu Zhang, and similarly, Yu Zhang will not go to the princess's mansion all year round.

As Eucommia ulmoides gum, Yang Heng also put out the matter of the Eucommia ulmoides tree plantation, and signed an agreement with someone to recycle the skin and leaves of Eucommia ulmoides, and in this regard, Yang Heng only retained the initial processing project of Eucommia ulmoides gum, and the deep processing was also auctioned out, this, Yang Heng will choke their necks from the source of the supply, and Yang Heng will not have his own factory for carriages and wheel water pipes, this, the initial processing is not that Yang Heng does not want to auction it out, but he needs to consider the problem of pollution. Once this thing is also auctioned out, then Datang will be in a deeply polluted environment, so, at present, as a rubber wheel carriage ox cart, it is still a high-end product, for a long time, this rubber wheel and the original wooden wheel car, still need to be together.

Then there is the academy, which has completely incorporated everything in the mountains, and even has attached mines, blast furnaces, steel furnaces and other things, these are all test supplies, naturally, it is also possible to use them as emergency processing.

Finally, in the twelfth year of Zhenguan, Yang Heng prepared to plant a new product together on his Zhuangzi, his father and uncle's Zhuangzi, and the Zhuangzi of the two princesses, that is, corn, and a seasoning vegetable, that is, chili.

Similarly, in this era when horses are the main means of transportation, a small pasture still needs to be had, this pasture, Yang Heng and people have collected many kinds of seeds, all along, Yang Heng has neglected this pasture aspect of things, so Yang Heng also needs to make up for this lesson.
