The demand for iron materials for laying railroad tracks was very large, but fortunately, the imperial court attached great importance to this, and used the black technology of black powder to first mine iron ore on a large scale in the land of Guanzhong, and then spread it to all parts of the country, so that the imperial court could obtain a steady stream of large quantities of pig iron raw materials.

At the same time as the quantity increases, the price of pig iron has fallen all the way, which is very beneficial to the popularization of iron agricultural tools, and the ordinary people are all very happy, but those traders who stored a large amount of pig iron earlier have suffered extremely heavy losses, and the huge wealth has evaporated instantly.

Of course, the decline in pig iron prices is generally more good than bad, these traders who jump into the river, after all, are only a very few, and who makes them too greedy?

The fall in the price of pig iron is also a loss for the miners who mine iron ore, but after the use of black powder, the production of pig iron has increased many times, so that it makes up for the loss caused by the price drop, and even earns more.

In addition, the imperial court is also organizing forces to mine iron ore, even if these private iron ore owners, united to reduce production capacity, can not stop the trend of falling iron prices, but will allow themselves to completely lose this market, in order to make more money, they can only continue to mine desperately, with production to make up for the loss caused by the price drop, at the same time, will also make the price of pig iron fall further, unless the price falls to unprofitable, otherwise, these iron ore owners will not stop.

Against the backdrop of a huge production of pig iron and low prices, the laying of rails is going very smoothly, and there is no shortage of raw materials in the major manufacturing production areas.

In order to build more and farther railways in the future, the imperial court took advantage of the opportunity of low prices in several major core cities to store a large number of pig iron raw materials, among them, Changlefang in the north of Chang'an City also built a huge warehouse to store a large number of pig iron raw materials.

The laying of the rails is in full swing, and everything is going well, and the weather continues to warm, and summer is fast approaching.

Ang Lee's annex, after nearly half a year of meticulous work, has been completely completed, all the facilities are very complete, and living in it is even more comfortable than the palace.

In order to escape the scorching heat, Ang Lee temporarily moved his mansion outside the city, leaving only seven or eight servants in the mansion inside the city to guard the house.

The area of the mansion is 50 acres, for this reason, the internal space is still very large, a total of more than 20 courtyards of all sizes have been built, and the functional facilities are complete, so that the craftsmen involved in the construction are amazed.

The main house is in the middle of the middle of the building, a three-story building, the facilities are much more powerful than the facilities of the main house in the city, it is a warm winter and cool summer design style, fully considering the conditions such as heat insulation and ventilation, and even built ground energy facilities.

The so-called ground energy equipment is to bury a long metal hollow pipe into the ground, and two interfaces are left in the room, one is used for air and the other is for gas out.

After the warm air in summer is blown into the metal pipes, after a little underground walking, it will be cooled to a low enough temperature, and then blown out of the outlet to fill the room with cold air, and with the continuous blowing and out, a large amount of hot air in the room will be cooled into cold enough air, so that people can stay in it very comfortable.

Moreover, geoenergy equipment can not only be used for cooling, but also for heating in winter, one device has two functions.

Three-storey small building, each floor has a setback, on the second floor of the setback, built a sun room of all-steel medicine, when the weather is cold, you can lie in the sun inside, in addition, used to dry the quilt, there is no need to worry about dust, and there is no need to worry about the sudden rainstorm.

There are study rooms on the first floor and two floors, each master bedroom has a separate room, a dining room for eating on the first floor, and even a bathroom for bathing is also built inside the main house, and it is more advanced and convenient, the hot water boiled on the outside of the main house can flow directly into the bathroom through the pipe, which is convenient and fast.

On the side of the first floor of the main house, near the bathroom, there is an indoor swimming pool, the area is one zhang wide, three zhang long, it can be regarded as a very large indoor swimming pool, and outside, there is also a swimming pool, of course, the area is large, there are three zhang wide, ten zhang long, the depth is very consistent, all are five feet deep, adults will not be submerged when standing inside.

There are only two small houses on the third floor, and in addition, there is a large terrace on which astronomical equipment can be placed, and at night you can stand on it and watch the stars, and during the day, you can also see the surrounding scenery far away.

The courtyard of the main house is the largest courtyard with the largest investment, and in the adjacent courtyard, there is a special back garden courtyard, planting all kinds of precious flowers and trees, and an orchard planting fruit trees.

As soon as she lived in the other courtyard, Yan Ruyu's eyes suddenly lit up, and after just one glance, she completely liked this place, because it was so beautiful, and the place where you could play was much bigger than the mansion outside the city, and the room in the main house was very cool, and it was very comfortable to stay inside.

"Ruyu, do you like it here?"

Ang Lee asked proudly.

"I like it, I like it so much, it's so beautiful here, we'll live here in the future."

Yan Ruyu replied excitedly.

"Madame doesn't want to go back to the city?"

"Well~~ It's okay to go back once in a while, after all, the houses in the city have lived for so long, and they have feelings."

Yan Ruyu replied.

"Madame is quite nostalgic, it's so hot today! Let's go swimming! ”

Ang Lee proposed.

"Swimming? Husband, I won't! ”

Yan Ruyu shook her head.

"It's okay, I can teach you, my wife is so smart, she will definitely be able to learn."

Ang Lee smiled evilly.

"Husband, your clothes will get wet."

Yan Ruyu was a little reluctant in her heart.

"Wet clothes? Whoever told you to go down in your clothes, of course, had to take off your clothes. ”

Li An said seriously.

"Ah...... If you want to take off your clothes, how can you do this, you are ashamed, you are ashamed. ”

Yan Ruyu looked at Li An angrily, her little face full of shyness.

"What is there to be shy in front of your husband, and there are no outsiders here."

Ang Lee quipped.

"That's not going to work! In broad daylight, how ashamed! ”

Yan Ruyu still couldn't accept it.

"Come on! Madame, I have prepared a swimsuit specially designed for swimming, and Madame must be beautiful in a swimsuit. ”

Li An pulled Yan Ruyu to the small room next to the indoor pool.

"Ah...... Husband, this is the clothes? ”

Yan Ruyu held the three-point swimsuit of the later generations, and her brows were tightly locked.

This was designed by Ang Lee himself, selected the materials, and made by the best tailors in the capital.

"Madam, this is a swimsuit, it will be beautiful to wear, it can show Madame's perfect body, come, quickly change it."

Li Ang urged, and took off his clothes and put on the big pants for swimming.

"Husband, how do you wear this!"

Yan Ruyu hid behind the curtain and took off her clothes, but she didn't know how to put on her swimsuit.

"Madam, let your husband help you dress!"

Ang Li walked over, personally helped Yan Ruyu put on a swimsuit, and touched a few handfuls by the way.

"Hmph, this swimsuit must have been invented by my husband! Ordinary people wouldn't invent such a thing, would they? ”

Yan Ruyu looked at Li An with a disgusted expression.

"Of course, this swimsuit is specially made for the husband and the wife, come, stand up, let the husband appreciate it."

Li An took a few steps back, wanting to see what Yan Ruyu looked like in a swimsuit.

"Wow, what a beautiful, such a beautiful body."

Li An's eyes are almost straight, Yan Ruyu's figure is really not to say, it is a hundred times stronger than those bikini beauties that I have seen in later generations, and her skin is fairer and more attractive.

"Ma'am, pose."

Li Ang asked with a smile.

Yan Ruyu smiled and posed a few times casually, one more beautiful than the other, one more charming than the other, looking at Li An's eyes not only straight, but also something straight.

"Husband, it's a shame to dress like this!"

Yan Ruyu crossed her arms in front of her chest, with a pitiful look.

"Eh, in front of my husband, what is there to be ashamed of, come, let's go down and swim."

Li An smiled evilly, and pulled Yan Ruyu out of the swimming pool, because it was an indoor swimming pool, he didn't have to worry about being peeped at by outsiders.

"How's that, ma'am, be comfortable!"

After playing in the pool for a while, Ang Lee felt very comfortable.

"Well, it's really fun, hee-hee."

Yan Ruyu said, poured a handful of water on Li An's head, and dodged it with a smile.

"Haha, dare to sneak attack me, see how your husband teaches you."

Li An set off a huge column of water and splashed it on Yan Ruyu, who was fleeing, and Yan Ruyu was startled and shouted for help.

"Haha! No one will come to your rescue if you shout at your throat, hahaha! ”

Li An suddenly hugged Yan Ruyu from behind and pressed Yan Ruyu on the railing.

"Husband, no."

"What's not to do, there are no outsiders here."

Li An knew by looking at his expression that Yan Ruyu wanted to refuse and welcome, and the movements in his hands were of course more daring.

Then, there was an intoxicating popping sound in the pool.

In the following days, every time it was hot at noon, Li An would play in the swimming pool with Yan Ruyu, and a few times he boldly ran to the outdoor pool to play, anyway, the mansion was surrounded by courtyard walls, and no one would peek at all, and in the main house, there were generally only three maids, Cao'er, Xiao Yin and Xiao Meng, and it didn't matter if they found out, it was a big deal to let them come down and play together.

"Ah Lang, King Guangping, they are here."

Cao'er walked over to the outdoor pool and whispered.

Li An had just finished refreshing, his breath was a little weak, he put his arm around Yan Ruyu's shoulder, and whispered, "Madame and Cao'er are playing here!" King Quang Binh: They're bothering me again. ”

"Husband, go quickly! Don't let King Quang Binh wait. ”

Yan Ruyu is still quite reasonable, at least Ang Lee thinks so.

Taking off his swimsuit and big trousers, Ang Li put on a summer dress, and left the main house and went to the main hall more than 100 steps away, where Li Yu and Li Li were waiting for themselves?

To say that Li Yu and Li Li, the frequency of coming over recently is getting less and less, about seven or eight days only once, one is because the weather is too hot, I don't want to run so far, the other is because I also have homework to do, there is not much idle time, of course, there is also a reason that the novelty is getting less and less, Li An can invent again, but there are only those things, it is impossible to invent a good thing every day, sometimes it is really boring to come.

In addition, as the weather gets hotter, as soon as the sun rises, the rails will become extremely hot, which makes the two no longer dare to sit on the rails, so they have to run to the main hall of Ang Lee's mansion.

"Why are there only cucumbers, and you don't drink anymore?"

Walking into the main hall, Li An saw Li Yu and Li Li holding a cucumber and had no intention of drinking.

"Li Shilang, this weather is too hot, and it will be even hotter after drinking, so you can't drink it."

Li Yu said truthfully.

"That's what the King of Quang Binh said! It is true that the weather is too hot, and those who are hot have no appetite, but it would be nice if there were ice cubes to eat. ”

Ang Lee said with a smile.

"Ice cubes, isn't there no ice cubes in Li Shilang's house? Your housekeeper said that he forgot to store it last winter. ”

Li Yu said that when he first came, he asked Zhao Liu for ice cubes to relieve the heat, but Zhao Liu said that there was no ice cube storage in the mansion, so the two of them were very helpless and had to endure it.

"Yes! My mansion was just built last year and I didn't store ice, but it doesn't matter, I can make it fresh! ”

Ang Lee replied with a smile.

"Freshly made, ice cubes are winter things, and you can make ice cubes on such a hot day?"

Li Yu and Li Li's eyes widened, with an expression that I don't read much, don't lie to me.

"Of course you can make ice cubes, you wait, I'll make ice cubes for you in a while."

Li An turned to leave, and asked several male servants to go separately to prepare, and after a while, a large clay pot, a small clay pot, a large bucket of saltpeter, and a large bucket of water were ready.

"Li Shilang, these things can make ice cubes?"

Li Yu and Li Li looked at these four things in surprise.

"Of course, these things add up, it's an ice-making artifact, come, let me demonstrate it myself, you can see it."

Li An said as he first put the large clay pot on the table, and added a large amount of water to it, then put the small clay pot to float inside, and then add water to the small clay pot.

"You see, the moment to witness the miracle will soon come, keep your eyes open."

Li An poured the saltpeter in the bucket into the water of the large clay pot little by little, and a large number of bubbles surged in the water in an instant, and made a unique clattering sound.

"Ice cubes, there are really ice cubes, the water in the big clay pot is frozen, it's amazing."

Li Yu screamed in surprise.

"Look, the water in the small clay pot is also starting to freeze, it's really frozen."

Li Li looked at the small clay pot and screamed in the same surprise.

As time progressed, the ice cubes in the two clay pots grew larger and thicker, and soon reached the standard of consumption.

"Feel it and see if it's the ice you need."

Ang Lee took out the ice cubes in the small clay pot and divided them among the two of them, so that they could experience the newly made ice cubes. (To be continued.) )
