"I asked you to get the bellows, how is the blast furnace?" The mainland is basically unified, Xu Yuanxuan will go back to Beijing for a few days without moving, and occasionally come back with the fighting machine that transports things back and forth and soldiers.

Hideyoshi spread out, pointing to a strange-looking thing behind him and said, "This is the blast furnace, bellows, and the first prototype steam turbine that you said." ”

This is... A strange thing that Xu Yuanxuan had never seen at all, it looked like a pyramid as a whole, and the top of the tower was cut off. Wide at the bottom and narrow at the top, trapezoidal on all sides, there is a combustion chamber, and where it is connected is a hydraulic blower.

The fundamental reason why Xu Yuanxuan needs to build this thing is not because it is useful, but because he wants to use this primary product for teaching purposes. Without this simple version of the primary product, how can workers directly operate more sophisticated high-end goods?

"Master, what are you doing here?" Meilan, Zhuju, poetry, books, etiquette, spring, summer, autumn and winter, these twelve girls are now also calling Xu Yuanxuan to be the master, you are all masters, you are always embarrassed to attack us, right?

They never knew that in Xu Yuanxuan's world, some masters like to attack their apprentices... For example, a certain little dragon girl... Cough.

Therefore, even if they called Master Xu Yuanxuan, the difficulty of protecting Zhen Ying increased, not decreased. Of course, it depends on whether Xu Yuanxuan is such a beast... It's a pity that he's such a beast man! It's better than a beast, right?

These twelve girls are Xu Yuanxuan's current focus on cultivating, not because they want to take the opportunity to pull a relationship, but because these girls have undergone brain development, making it easier to learn new knowledge.

He even had the urge to send them back to Earth for a modern education...

However, this may make these girls directly doubt their lives, so Xu Yuanxuan decided to take his time... First of all, let them understand that machines are more capable than humans.

"Well, it's a device that can make iron. "Even though Hideyoshi made this thing out of the four dislikes, let's call it a blast furnace... Right?

A complete blast furnace is of course very simple compared to other modern industrial products, but compared with the most advanced high-tech product "shotgun" of Finsroxing, it is simply a set of extremely complex things. Therefore, Xu Yuanxuan's blast furnace does not have so many messy designs at all, there is only one feed port, a combustion chamber, a tap port, an air intake chamber, and a blower.

Xu Yuanxuan explained the principle of the blast furnace to the girls, and at the same time harvested the worship value of the girls, and by the way, the blast furnace built by Hideyoshi was worthless.

Hideyoshi listened with a smile and memorized all the main points, so that he would not make the same mistake when building a blast furnace in the future.

Xu Yuanxuan explained, "The efficiency of the blast furnace is only related to one thing, and that is... Well, Xiaoju, tell me..."

Seo Won-hyun wanted to see how far these girls had understood.

Xu Ju thought for a moment, his eyes lit up and said, "The quality of iron ore!"

This is certainly a bit reasonable, but the quality of iron ore is natural and cannot be controlled artificially, which is obviously not the answer Xu Yuanxuan wants.

"I mean the part that can be controlled by humans, but the quality of the iron ore does matter. "This is also the reason why China still imports a large amount of iron ore every year. China's iron ore is basically iron ore with very high impurities, and compared with high-quality iron ore from Brazil, Australia, and India, there are too many magazines and too little iron content.

Xu Ju thought for a moment again, and said hesitantly, "The wind... Is it?"

She saw that Xu Yuanxuan attached great importance to the blower, because of the relationship of this blower, the entire blast furnace was built at the water's edge.

"No, the wind is only a symptom, you have to see the essence through the phenomenon, learn to arm yourself with materialist ideas... Bah. Wind power is also for the service of firepower, so the efficiency of a blast furnace, to put it bluntly, is only related to firepower. Whether it is the overall shape of the blast furnace or the need for a hydraulic blower, it is all about increasing the firepower. Well, now this blast furnace is wrong, the correct one should be similar to a pot. The pot Xu Yuanxuan said is not the kind of kettle that is usually used to boil water, but a container that Finth Luoxing usually uses to hold water at home, which is very similar to the appearance of a blast furnace.

Hideyoshi hurriedly wrote it down...

"So to say this... What should I do?" I heard that it took Archon Hideyoshi a lot of effort.

"What else can I do, unqualified, demolished and rebuilt. Xu Yuanxuan responded domineeringly.

Hideyoshi didn't say anything, and there was no loss in his eyes, he had never touched this thing, but he listened to Xu Yuanxuan say a few words from time to time, and took some specious information that Hua Guorui said.

Hua Guorui is teaching Xu Yuanxuan, he naturally won't even write in the very basic knowledge of the shape of the blast furnace, Xu Yuanxuan also thought that Hideyoshi had seen the blast furnace, so he made such a fuss.

However, the accumulation of technology is a thing that learns from countless failures, and this failure is completely irrelevant, although it is completely avoidable... However, at that time, Xu Yuanxuan was in a hurry to go home to find his wife. It wasn't until he got tired of Zhu Yumeng that he came back, and when he came back, Hideyoshi's strange-shaped blast furnace was finished...

At that time, I hadn't touched my sister for a month, and Xu Yuanxuan was really... Some are.

Then Seo Won-hyun slipped away again... Leaving only Hideyoshi and a bunch of girls messy in the wind.

Xu Yuanxuan this time, well, theoretically there is indeed something wrong, he is going to give those people the textbooks of Chinese, mathematics, physics, and chemistry for junior high and high school. He felt that everyone including Hideyoshi needed to relearn these basics. Of course, this is only by the way... But as soon as he arrived at Zhu Yumeng's house, Xu Yuanxuan received a thunderbolt on a sunny day--- Zhu Yumeng was pregnant again.

Xu Yuanxuan sighed, "Why just slam you, there is a little Ding Ding again?"

Zhu Yumeng smiled and slapped him: "I am pregnant, you don't seem to be happy..."

Xu Yuanxuan is really unhappy, and when she is pregnant with a child, she can't do some exercises that are beneficial to blood circulation and physical health.

"Hey, I owe it to these bear kids. Uncle Yue knows?"

The bear child who was holding a bottle by the bed rolled his eyes, I owe you a debt in my last life, okay?

My father is so naïve, it seems that I can only wait for this baby to grow up and take him to fly.. Well, whether it's eating chicken or being the king, the baby will play a good game!

The young bear child has set a grand ideal, and the double row takes the father to the king...

Come on, bear child!

Zhu Yumeng lay lazily on the bed, as if she was a little weaker than when she was pregnant last time.

"Of course, my father already knew, and the doctor also came to see it, saying that the interval between my two pregnancies was a little short, and suggested that the child should be killed, but I didn't agree. ”

Xu Yuanxuan frowned: "This group of imperial doctors knows how to be stable... Don't be afraid, I've got you. ”

Xu Yuanxuan held Zhu Yumeng's hand.

The two stayed like this for more than ten minutes, feeling the warmth carefully.

The bear child was speechless, "The baby is still so young, you two will sprinkle dog food, is this okay?"

It was said directly, although it was said very slowly, and the voice was milky, but the words were very clear.

The bear child opened his mouth to speak, and it was already the last time Xu Yuanxuan came back. At that time, Xu Yuanxuan had just entered the door, and the bear child came and said, "Stinky daddy is back to rob my mother with me!"

At that time, Xu Yuanxuan was almost mixed by the door frame.

Your mother is not your personal belongings, I at least own more than half of it!

"If you don't want to eat dog food, you can go out..."The crib has a small rocking handle, the bear child is naturally strong, can shake that thing, shake it in a clockwise direction, the small bed can move forward and backward, but it is also limited to indoors, want to get out of the house, this car can not pass the threshold.

Of course, it doesn't exist.

As for the inevitable being fed a few mouthfuls of dog food on the way to the play, of course, it doesn't matter. Who doesn't get fed a few mouthfuls of dog food when they watch a movie? Some movies are fed dog food from beginning to end, don't you also watch the single dog being strangled to death?
