The rainy season in Guanzhong is coming, and I don't know how long it will take to rain in the autumn of West China after that, Zhang Yang is also preparing to repair the roof of the library pavilion, the stairs will collapse because of the dampness, to keep the library dry, the roof structure to be re-paved.

Otherwise, when the autumn rain in West China comes, even purple wood can't prevent moisture, Zhang Yang is still thinking about how to do a good job of moisture-proof, and he can't hang bags of lime in all corners and roofs.

"Brother-in-law!"

Hearing a loud shout from under the mountain, Zhang Yang was stunned, and once again confirmed that it seemed to be Li Tai's shout.

Li Yue stared at his younger brothers and sisters to do the question, thinking that there was no one else except Li Tai.

Then I looked towards the stone steps down the mountain, and saw Li Tai rushing over, and the fat on his face shook because of running.

Because of the casting of the steam engine, Li Tai, the fat man, has been using his brain a lot and eating a lot recently.

Finally approached, he couldn't run anymore while panting, and sat down with both hands on the stone steps, stretching out his hand and pointing into the distance, "It seems to be...... Brother-in-law, let's take a look. ”

The fat man's face turned red from running.

Zhang Yang walked down the mountain and helped him, "It's the steam engine that has a problem." ”

Li Tai grabbed it with both hands, and there seemed to be light in his eyes, "The wheel of the steam engine is spinning, it is spinning!" ”

"Okay, okay, don't get excited." Zhang Yang had no choice but to follow down the mountain.

At this moment, there was a behemoth beside the blacksmith that was making a noisy noise, and when they approached, the voice became louder and louder, and the whispered discussion was soon drowned out by the movement of these big guys, and everyone had to speak in amplified voices.

Zhang Yang walked closer and stopped, the appearance of the steam engine in front of him was very strange, but looking at the turning wheels, and then listening to the whistle, he seemed to have returned to his previous life in a trance.

When I came back to my senses, I was still surrounded by Li Tai and these people.

"Brother-in-law......" Li Tai said tremblingly, "Is it made?" ”

Zhang Yang smiled and nodded, "This is a big step for Lishan, congratulations to His Royal Highness King Wei and congratulations to the Tang Dynasty." ”

Li Tai jumped up happily on the spot, "It's better to be instructed by my brother-in-law." ”

"I'm just pointing out some scratches, this steam engine is the brainchild of His Royal Highness King Wei from beginning to end."

In addition to the excitement, Li Tai sat down on the ground with an unheard-of sense of accomplishment in his heart, three years, three years of hard work was not in vain.

From the first understanding of air pressure seven years ago, the conjecture of air pressure, to the rise of hot air, step by step from the most basic common sense of air pressure.

It's been seven years, and Li Tai has gone from ten to eighteen years old, and he is still so fat.

The steam engine can change the current pattern of Lishan and raise the productivity of Lishan to another level.

Li Tai sat paralyzed on the ground, looking at the big guy who was swallowing steam and couldn't speak for a long time, and for a while he hid his face and cried, these two years have been too difficult.

"Brother-in-law, you know what? I wanted to give up several times. Li Tai's words were a little choked, "But every time I want to give up, I feel heartache in every way, we are thirty people up and down, three years of hard work!" After thinking about it like this, he gritted his teeth and insisted, from the pipe to the stove, overturned it dozens of times......"

He began to talk about the technical problems of steam engine casting, in order to overcome these technical problems, Li Tai lost his temper, and in order to succeed, he also reached a point of no cost.

Fortunately, now that he has succeeded, Li Tai is also relieved, and at this moment he feels that the whole person has been sublimated.

Zhang Yang looked at Li Tai's current situation, if he didn't succeed this year, he would probably collapse.

He is such a child, from childhood to adulthood, as long as he doesn't understand something, he has to find out to the end, even if it is a few days and nights without sleeping.

Zhang Yang also recalled that seven years ago, he hugged his leg on Suzaku Street and asked for air pressure.

He hasn't changed since he was a child.

In a trance, he was still the same little fat man back then.

Master Jiang watched this scene from afar, and His Royal Highness King Wei shouted to Zhang Yang's brother-in-law one by one, he held on to his gray beard, lost his mind for a while, and suddenly understood something.

Everyone in Lishan knows that the owner of Lishan is the brother-in-law of His Royal Highness King Wei, but at this moment his old man finally figured it out.

So it was, no wonder he ......

"It should be like this, it should be like this." Master Jiang muttered to himself, and walked into the blacksmith workshop in a daze, at this moment, the people in the blacksmith workshop had gone out, and the furnace had been extinguished.

He went into his room and took out a box from under the table, which contained silver cakes that had been intended for him.

It's only now that I understand that he is the master of Lishan and the county marquis of Lishan.

Usually he doesn't look like a county marquis.

"Yes, how can he be such a smart child, how can he have been working under King Wei, the one who married the princess to benefit Lishan, who else would he be." Master Jiang smiled, and his mood at the moment was very complicated.

Outside the blacksmith's workshop, the steam engine has been in operation for an hour, and next to the steam engine is a step that people can step on to add water.

The longer the steam engine operated, the tin box couldn't help shaking, but fortunately, it was running very steadily.

Zhang Yang looked at everyone and was still in the joy of success, the world is always so interesting.

It has been three years since the steam engine was designed and now cast, and in the past three years, Li Tai has overcome many technical problems.

The most difficult of these are precisely some very small details.

These details are like a roadblock, blocking the process of steam engine casting, and also reflecting the symptoms of the incomplete development of Lishan's industry.

Only one of the most common and simple processes in metal processing, just a chamfer has become the key to the success of the steam engine.

This is what makes Zhang Yang want to laugh but can't laugh.

There is still a long way to go in the refinement of the casting process.

Perhaps this steam engine is more than three times larger than the steam locomotive of later generations, but this is the steam engine of Datang.

Just looking at the wild and simple appearance, there is a barbaric atmosphere everywhere that the Tang Dynasty should have.

The germination of technology is like a newborn baby, it will get better and better, and if it is improved on this basis, the steam engine will be more refined in the future.

I can't remember how later generations of people forged the steam engine.

But in Datang, this is the hard work of many technical backbones in Lishan for three years, and the amount of manpower and material resources consumed is incalculable.

At this moment, I feel that my efforts are worth it.

Zhang Yang left the joy and emotion to everyone present, and left the crowd.

Also leaving the crowd at this time was Li Shimin.

"Does this steam machine keep spinning?"

Hearing His Majesty say this, Zhang Yang smiled: "Then it depends on where its load limit is." ”

Li Shimin frowned and sighed: "I can't see through the current Lishan. ”

Zhang Yang shook the fan in his hand, "When does Your Majesty plan to use the vegetables of Lishan to feast on the important ministers of the court." ”

The steam engine belongs to the steam engine, and the affairs of Taifu Temple cannot be stopped.

Li Shimin hesitated for a long time, and then said: "In October, I will tell them about the results of Taifu Temple. ”

"Thank you, Your Majesty."

"You haven't said what that thing is for."

Zhang Yang accompanied the emperor all the way, "Without it, it is nothing more than to improve production efficiency, knowledge is technology, technology can improve productivity, with the steam engine can make our Lishan industry take off, and in the future, Lishan can have a power source." ”

"Power source?"

Seeing that the emperor still didn't understand, Zhang Yang said with a smile: "Your Majesty also sees that most of the labor in Lishan now needs manpower, but as long as there is this steam engine, it can replace a lot of manpower, so that we can produce on a large scale, and at the same time, the manpower saved can continue to develop in technology, I plan to let our Lishan people master technology." ”

For the rest of Datang, slash-and-burn farming has always been the main keynote, even if it is not slash-and-burn, the manufacturing technology of the outside world is still a cut behind Lishan.

Lishan is one step ahead of the outside world, and now that Lishan has a steam engine, Li Shimin can no longer understand how far the outside world is from the current Lishan.

After looking at the production of Lishan, we will look at the productivity of other places that have been built up with manpower.

If you really want to describe it, it can only be said that there are two worlds.

The gap between Lishan and the outside world is already very large, and this gap will only get bigger and bigger in the future.

Li Shimin looked back at the big guy who was trembling and puffing smoke and dust, "I will watch you Lishan until the day you are done." ”

"By Your Majesty's auspicious words." Zhang Yang smiled and accompanied the emperor, "By the way, there is one more thing I hope Your Majesty will answer." ”

Li Shimin nodded slightly, "You say." ”

"Now that the steam engine has been completed, with our current production capacity needs in Lishan, this one is not enough, and because of the manufacturing needs, the size and style required are also different, which is just a small step for our Lishan."

Li Shimin nodded and said: "In this way, I also think that there is nothing to be surprised about, as long as you make a strategy and a secret recipe for the palace, you can also make it." ”

Zhang Yang said with a smile: "How can Lishan be compared with Your Majesty, I am smiling, in the future, Lishan will build a big academy to train more technical talents, and I plan to build it in Lantian County." ”

"The opening of the academy is beneficial to the people, and it is beneficial to the community, and I will not refuse, and I will allow you to build a academy in Lishan."

Saying this, Li Shimin still turned around to look at the steam engine more, and then planned to go to see Shangguanyi.

The emperor was not interested in the steam engine, he preferred that the court could recruit more talents, and Shangguanyi was indeed a good person.

Zhang Yang walked around the village, where the villagers were sorting out the wheat, and some of the flakes were glued together with the grains to pick out the tender wheat.

The villagers will boil the wheat and eat it, which is also good.

Although it is difficult to swallow, this food has fiber and energy required by the body, so it is good to eat once in a while.

If the wheat harvest is too poor, people will also eat this kind of wheat that does not grow well.

In fact, there is another saying for this kind of wheat, called oats.

In the north of the Hetao or Hebei, Turkic and other places because of the relationship between water, soil and climate, the perennial temperature is not high, and this kind of wheat will also grow.

Zhang Yang packed some and took them away, and took them to Lishan under the surprised eyes of the village women.

It wasn't until the wife explained that these village women didn't care.

The main reason is that the county marquis of Lishan has rarely appeared in front of the villagers in the past two years, so that now this simple person with a stubble face and a simple dress can't recognize it as the county marquis here for a while.

My wife and her neighbors have a total of five families, and after being arranged by Shi Tong, they can do some simple work, such as picking wheat.

As the teacher's health has deteriorated in the past two years, the teacher's wife has also aged very quickly in the past two years, and now there are more gray hairs than black hair.

Time can't keep people, even if Lishan is well recuperated, it can't stop the deterioration of the teacher's illness.

Zhang Yang returned to the mountain with a bag of wheat.

After listening to the class, the children were very depressed in the face of the homework that the royal sister had just assigned, and they were not energetic after listening to the class all afternoon.

It should be said that the children have no energy in the past month, and Li Yue was close to giving birth before and relaxed the children's curriculum.

Now is the time to catch up with the progress of learning, and the study task is heavy.

When he came to the kitchen, Zhang Yang washed the oats, planning to make oats for the children.

Li Yue held the scroll in his hand and said curiously: "Today, what's wrong with Qingque?" ”

"The steam engine is finished, and it's burning outside the village."

"Does this mean that we will need more iron and coal in the future?"

The daughter-in-law is very attentive to the development of the village, and for her, the village has gone from poverty to prosperity to prosperity jointly arranged by the husband and wife.

"But as early as the first two years, we hoarded a lot of iron and coal, and we can use it for two or three years, there are many coal mines in Liaodong, it's time to talk to your father."

"Hmm." Li Yue smiled.

Oats are not as delicious as those of later generations, and they taste coarse, and after they are made, they become a snack for younger siblings in the afternoon, and they are not picky eaters.

It has been a month since the child was born, and when his aunt held him, a pair of bright eyes looked at this home curiously, and every detail could make his eyes glow with curiosity.

At night, Zhang Yang, who was drinking tea and reading a book, heard the whispers of his daughter-in-law and Xiaohui in front of the house.

Xu Hui plans to use the name of Taifu Temple to drive the Chashan mountain people in Jiangnan East Province, and give them enough benefits to buy some patriarchs and village heads, but they still need money.

Li Yue also quietly handed over the seal letter of Taifu Siqing to Xu Hui.

Zhang Yang didn't know about these things, and he pretended not to hear them.

Zhang Yang looked at the volume of "Taishi Gongshu" in his hand, Taishi Gongshu is also the Historical Records, but after Sima Qian finished writing the historical records, he was separated by several dynasties, and there were many names.

These are all books collected from outside, and it is difficult to collect complete historical records even in the Tang Dynasty.

But now you can see the original appearance of some historical records, the font of the official script looks more laborious than the regular script, and the problem of understanding is not big.

This volume is written that the Duke of Qi Huan worshiped Guan Zhong as the prime minister, so as to dominate the Central Plains during the Warring States Period.

Li Yue was in a good mood, humming the tune that the couple had hummed together before, "Husband, let's sing together." ”

Zhang Yang put away the scroll in his hand, "What do you want to sing." ”

She is already a mother of two children, and she still laughs like a child, "Twinkle and twinkle!" ”

"Okay." Zhang Yang opened his mouth first, and the couple sang in the room.

The two aunts cleaned up the children playing around the Huaqing Pond, and listened to the songs sung by the couple in the house, and they had a lot of smiles on their faces.
