The courtyard in the middle of the castle is roughly a rectangle close to a square.

There are five outward bumps around it, and if you look down from above, it looks like a cartoon figure with very short hands and legs.

It was originally a military fortress with fifteen meters high and two and a half meters thick walls, and cannons were erected on the walls.

The comfort of living in this kind of place certainly cannot be compared with that of a purpose-built holiday estate.

But after decorating well, if there are not too many people, it will not be too bad.

Because the place is spacious enough, the total area of the entire castle is almost 10,000 square meters, and the courtyard is more than 3,000 square meters.

Zhu Jingyuan didn't say that he was here for a vacation to escape the summer, and Lin Zexu didn't know that Zhu Jingyuan wanted to live permanently, so he chose here for safety.

Zhu Jingyuan stood in the middle of the courtyard, looking at the surrounding stone buildings, looking at the trees and seating pavilions in the courtyard.

Feeling the surrounding temperature of up to 29 degrees Celsius and the gentle sea breeze, I am quite satisfied with the environment here.

Zhu Jingyuan said goodbye to his staff and courtiers, and went to rest for a day to readjust to the feeling of stepping on land.

The next morning, Zhu Jingyuan officially accepted Lin Zexu's report.

In the conference room of the castle, Hao Zhongyi, director of the third textile workshop, led a group of workers to take out samples of the main products of the Mengxian textile factory and garment factory and put them on the conference table in turn.

After cleaning up here, Lin Zexu went to the conference room of the castle and began to introduce and show Zhu Jingyuan.

The first is to show the biggest advantage of the fabric – abrasion resistance.

Lin Zexu did not let Hao Zhongyi do the experiment on the spot, but took out the results of the experiment.

"Your Highness, this is a pure cotton woven cloth, after repeated scratching three hundred times, the warp and weft threads are broken, and the holes are directly broken.

"This is a rayon woven fabric, and it has also been scratched three hundred times repeatedly, and the result is basically no obvious damage.

"The last piece, still a rayon textile fabric, was scratched a thousand times, but only the weft threads that intersected with the direction of the scraping were broken, the warp threads were still connected, and the fabric as a whole was still not completely pierced.

"The samples we sent to the Jingshi were displayed on the spot at the Governor's Mansion, and the Governor's Mansion arranged for soldiers to conduct on-site experiments.

After seeing the results of this comparison, the Governor's Office decided to purchase it on the spot.

"In the future, the appearance materials of training uniforms in spring, autumn and winter will all be changed to rayon."

Zhu Jingyuan had expected this, and after hearing it, he nodded with satisfaction.

Then Lin Zexu asked Hao Zhongyi to bring a set of clothes over, and the camouflage placket zipper was used as a training uniform jacket and pants.

Daming originally had a pair of cardigans, and after having a zipper, he put it on directly, and it was a normal result to make this kind of clothes.

The fabric has actually been shown, and the most important thing on this dress is not the fabric, but Zhu Jingyuan's newly invented zipper.

The zipper is an inconspicuous thing in modern times, but it is definitely one of the most important inventions in human history.

And the earliest zippers were not the most common styles in modern times, but two rows of thick metal hooks.

It took almost thirty years from the invention of the north to the basic maturity and the formation of the modern form.

Zhu Jingyuan's invention is still the same as always, directly based on the experience of later generations, and directly took out the three mature designs.

Lin Zexu took the zipper and pulled it back and forth twice, and was full of sincere praise for this invention:

"Your Highness's idea is so amazing, this is quite a few hundred small openings, which are closed or opened in an instant.

"It allows workers and soldiers to get dressed quickly, and to close packages quickly and tightly.

"As long as the mass production technology is mature, it will definitely become popular all over the world.

"And the orders of the Ming military can directly mature the related industries."

Zhu Jingyuan pulled the zipper back and forth a few times, pulled the elastic band of the sleeves and trouser legs, and wanted to sigh loudly:

This new style of training uniform has finally been made, and Daming is one step closer to modernization.

But considering the environment and identity, there is no way to say this emotion, and others can't understand it.

Zhu Jingyuan finally just nodded lightly, and said the word "good" sincerely, indicating that he was very satisfied.

Lin Zexu was accustomed to Zhu Jingyuan's reaction.

In Lin Zexu's opinion, His Royal Highness Prince Dashi has invented too many magical items, so he is already familiar with the novelty of new things.

No matter how important a matter seems to others, His Royal Highness here is only a slight nod.

But rewards and rewards are never stingy.

Hao Zhongyi saw Zhu Jingyuan for the first time, and it was also the first time he saw a person of this level.

Looking at Zhu Jingyuan's reaction, he couldn't help but admire in his heart:

"It is worthy of being the prince of the Ming Dynasty, and it is worthy of being the inventor of these magical things, seeing that they can be so calm......"

Next, Lin Zexu showed Zhu Jingyuan the various packages he had made.

A backpack made of thickened rayon fabric, as well as a crossbody bag and a handbag made of the same material.

Lin Zexu said with emotion:

"Compared to the zipper on the garment, the zipper on the package is much easier to use, and it is so easy to open and close to get things in and out.

"So these rayon zipper packages, plus the equipment for storing bullets, magazines, hanging pistols, and grenades, the Governor's Mansion of the Five Armies has also ordered a large number of them.

"Now all the factory has to do is to expand production and at the same time provide technology licenses to the royal consortium to build factories elsewhere.

"With the military's orders and authorized production costs, our synthetic textile mills and garment factories will be able to make a profit this year.

"The expansion of the synthetic textile industry will definitely increase crude oil consumption and increase the growth rate of crude oil sales."

Zhu Jingyuan flattened his mouth when he heard this.

The textile mill is going to make money on its own, and it can also push up oil sales......

In short, the big food country is making money no matter what it does now.

Zhu Jingyuan put down his clothes helplessly and picked up a pair of white socks next to him.

Lin Zexu immediately followed and said:

"These socks are made of 5/5 cotton, half stretch yarn, blended with stretch cotton threads, made by circular knitting.

"It fits perfectly on your feet, doesn't slip off easily, doesn't tighten, keeps you warm and sweat-wicks without getting loose and bloated.

"Available in different thicknesses and densities, suitable for all seasons of spring, summer, autumn and winter......

"This is the most popular product produced by our factory, which can be oriented to the entire Ming Dynasty and almost all groups.

"It's just that it takes time to roll it out, and we need to keep increasing production to reduce costs.

"In the short term, real low-level workers will not be able to afford it."

Zhu Jingyuan pulled the cuff of the socks, half into elastic silk, that is, 5 percent spandex, 95 percent cotton.

The warmth and sweat-wicking ability are the same as cotton, but with better stretch, it is also more comfortable to wear.

In later generations, the nominal "cotton" socks, as well as the pants of Laika, were basically at this level.

Pure cotton, which is not really elastic silk, is actually not comfortable to use:

"Send a batch to the palace, and I will wear this kind of socks in the future, and I can say that I will also wear them when I publicize it."

Lin Zexu immediately understood that this was using the name of Zhu Jingyuan, the prince, as an advertisement.

And Zhu Jingyuan is really reused, not purely famous, this thing is also a really good thing.

At this point, the relatively formal mass products of the two factories were introduced.

Zhu Jingyuan followed Lin Zexu and Hao Zhongyi and walked to the other end of the conference table, where there were more special products.

There was also a basin of water on the table.

Hao Zhongyi took a piece of cloth, wrapped it in his hand, soaked it in the basin, and then raised his hand again.

Hao Zhongyi didn't dare to speak in the face of Zhu Jingyuan, but Lin Zexu introduced beside him:

"Your Highness, this material and design can indeed make the cloth not stick after being soaked in water, especially suitable for wading.

"It's just that it can only be woven with pure rayon and elastic silk, and the market is relatively narrow, and the cost is difficult to suppress."

This is actually the swimming cloth, which is used to make swimsuits.

There is also a swimsuit next to it, of course, not a bikini of later generations, but a sports model with long sleeves and long pants.

Lin Zexu said that the market is narrow, and it seems that this is indeed the case at present.

This fabric is just non-sticky, and it is not waterproof.

Those who need to wade into the water either wear pants and go into the water, or use rubber waterproof clothing.

Swimwear can only maintain its image in the water, and this extremely special effect basically has no market in Lin Zexu's opinion.

That is, in some extremely special scenes, playing in the pool for entertainment.

Of course, people in this era can't imagine the grand occasion of men, women and children, all wearing swimsuits to play on the beach.

Zhu Jingyuan didn't say anything, and also tried the water-soaked effect of the swimming cloth, and looked at the end.

On top of the last tray, there was a pair of white pants folded up.

Zhu Jingyuan pulled it up and looked at it, and felt that this thing was a little strange, and the bottom of the trouser leg was connected with the foot.

And the overall look is relatively small, and it seems to be a child's pants.

Lin Zexu next to him continued to introduce:

"This East-West Daming Taixi clothing firm Chu Yuqiang's shopkeeper asked to make it.

"Eighty percent rayon and two percent elastic silk are intertwined to make elastic silk threads, and elongated cylinders are spun.

"This form of pants is made by making an opening on the inside of one end of the two cylinders, adding a piece of crotch cloth to each other, and sewing them together.

"The shopkeeper Chu said that this is equivalent to connecting the tight shorts and stockings worn by the Taixi people, so he is ready to sell them in the name of pantyhose."

Zhu Jingyuan finally understood what this was.

Zhu Jingyuan has never paid special attention to this thing in his previous life, and has always equated pantyhose with the thin stockings on a woman's legs.

The thickness of the pants in front of me is about the same as a summer undershirt, and it is completely opaque.

So much so that Zhu Jingyuan didn't immediately understand its identity.

After understanding what was going on, Zhu Jingyuan grabbed and pulled with both hands, and found that the elasticity was surprisingly good.

It doesn't look fat, but it should be able to fit in with an adult.

This is a custom-made product of the big food clothing firm.

This thing solves the pain point of the Tessie people for hundreds of years.

In the past, in order to assemble tight shorts and stockings, I had to leave a patchwork seam in the middle, and it can be completely disappeared in the future.

If the price of this thing is right, it will definitely sell well in the Tessie market.

Zhu Jingyuan thought of the situation over there, and subconsciously asked Lin Zexu:

"How much does this thing cost? Did Chu Yuqiang say how much he was going to sell this thing? ”

Lin Zexu picked up a small notebook next to him and looked at it:

"Cost...... It is not possible to estimate it particularly accurately at the moment, because it is difficult to share the costs of early development and trial production.

"The simple production cost is estimated to be about one yuan banknote, and it should continue to be reduced in the future.

"After discussing with us, the shopkeeper Chu felt that the ordinary ones had to be sold for ten yuan silver bills.

"The high-end styles sold to those nobles should reach twenty or even thirty yuan a piece."

Zhu Jingyuan calculated in his heart, the price of this pantyhose is also quite outrageous, and the cost is 100 yuan.

Under normal circumstances, two yuan silver bills can be sold in the market, which is two hundred yuan.

But Chu Yuqiang's plan for the shopkeeper is to sell for one thousand for the most ordinary ones, and for the high-end ones to sell for two or three thousand.

However, its current status is not a mass product of later generations, nor is it a cheap product.

Even if it becomes a cheap product sooner or later, it will definitely be positioned as a luxury product when it is just being born.

If Chu Yuqiang is completely allowed to operate alone, he will most likely maintain the positioning of luxury goods for a long time.

Maintain profit margins of 10x or even higher as much as possible......

After thinking about it for a while, Zhu Jingyuan said:

"The sales of this thing will be handed over to Chu Yuqiang himself.

"Don't sell on the market through other channels without consulting him or with my permission.

In addition, he told Chu Yuqiang that twenty or thirty silver bills were still conservative, and he could sell one hundred silver bills to try.

"According to the different proportions of elastic yarn and the different colors of the finished product, it is divided into different grades and sold to different people.

"In addition, it's still the old routine, let Chu Yuqiang go and send a few to Charles in France first, saying that it was my gift.

"Let this brother continue to help promote it, he should enjoy it himself......"
