From the north gate of Daming Palace to the Hot Spring Palace, there is only one feasible road, after this investigation, the railway line can basically be determined, so Li An does not plan to continue to waste too much energy on this. Pen "Fun" Pavilion www.biquge.info

Of course, a lot of specific work still needs to be done by the officials of the Ministry of Industry, so they also need to continue to explore this road, and measure the distance of each section of the road, as well as the amount of labor that needs to be used, and of course, there is also the cost issue, which must also be considered.

After handing over a lot of specific work to the officials of the Ministry of Industry, Li An took Li Yu and Li Li, under the protection of more than 30 guards, walked around the city wall, and went directly to the vicinity of the courtyard fifteen miles outside the south gate, where there were railroad tracks laid by Li An, which could be experienced by Li Yu and Li Li.

"Li Shilang, this is the railroad track."

Li Yu and Li Yu jumped off their horses, walked to the railroad tracks, and carefully observed the rails.

"Li Shilang, this is an iron-wheeled car that can walk on railroad tracks?"

They soon saw the bow of the iron-wheeled locomotive and the iron-wheeled carriage placed on it.

Li An didn't bother to introduce it, so he directly called a group of male servants, and took Li Yu and Li Li to experience it personally.

At this time, the length of the railroad track has been paved for six miles, and the feeling of experiencing it, of course, is far more than the feeling of taking the emperor to experience it last time, which makes Li Yu and Li Li very excited, and they feel that the railroad track is really powerful.

However, they also raised the same question, that is, whether the iron material was sufficient, and in addition, the transportation capacity was not strong enough, and Ang Lee gave a detailed explanation, so that they could initially understand Ang Lee's plan.

After getting out of the car, Ang Lee took the two of them to visit the processing plant again, so that the two of them could see all kinds of novel gadgets developed by themselves, many of which had just begun to be developed.

"Li Shilang, how can there be words on this clay? What is this for? ”

Li Li picked up a clay cube that had not yet been calcined and asked curiously.

"Be careful, don't break it, this thing is very important, as long as it is made, any literati in Datang can publish a book, and there is no limit to the number, even if it is only one copy."

Li An hurriedly took the clay block in Li Li's hand and explained softly.

This block of engraved clay that is being calcined is an important material for movable type printing, a technique that was only widely used in the Song Dynasty, and Li Ang intends to create this technology and present it to the imperial court as soon as possible, so as to benefit the scholars of the entire Tang Dynasty.

Of course, Li An can also choose to keep it for himself and open a printing shop in the capital to help customers who need small batches of books, but Li An is really not so greedy for money, the money he has now is no longer spent, in addition, the several industries that have been established will also provide him with a steady stream of wealth, and the imperial court will also give him a lot of money.

The most important thing is what important things he will develop in the future, as long as he is short of money, he can propose to Li Longji, with the financial backing of the imperial court, what else is there to worry about, and once movable type printing is promoted, it will benefit all the readers, then, in this way, Li An's status in the hearts of the readers will be greatly increased.

"Isn't that the first thing to be carved on a wooden board is to seal a book? Is this mud okay too? ”

Li Yu looked at it for a long time and asked.

"This is much easier to use than carving on wood, this is movable type printing, and when it is made, you will understand it after you use it."

Ang Lee doesn't want to explain too much, after it is made, it is good to let them see the finished product directly, and speaking with facts is the most powerful.

In addition, the development of the steam engine is also in progress, about the steam engine, the principle is really very simple, that is, the use of steam to push the piston, so that the piston drives the transmission mechanism, so as to drive the wheel forward.

But it is really not easy to make a steam locomotive that can be used, because there is no advanced processing machine tool, and precision parts cannot be manufactured, in addition, all transmission mechanism parts need to be built by hand, which has extremely high technical requirements for craftsmen, and it will be difficult to manufacture in a short time, and even, it may never be made.

Of course, no matter what the final success or failure is, Ang Lee will not give up, after all, once the steam locomotive is successful, it will greatly change the transportation situation of the Tang Empire and make a qualitative leap in the logistics of the Tang Empire.

In addition to movable type printing and steam locomotives, there are many other technologies being studied, and the most important one is medicinal jade, that is, glass.

The manufacture of glass is not difficult at all, as long as it is not too demanding, it can be made with clean sand and natural soda ash.

Ang Lee has now prepared a large amount of natural soda ash and clean sand in the processing plant, and a new blast furnace is being built, and once the blast furnace is built, the sand and soda ash can be poured into the furnace furnace to start making glass.

There are also some small technologies that are not worth mentioning, so you don't need to worry too much about them.

However, to be honest, there are too many strange things in Ang Lee's processing factory, so much so that Li Yu and Li Li, as soon as they came in, were like children in the zoo, looking everywhere and touching everywhere, which provoked Ang Lee to stop it, after all, some things can't be touched casually, and they are easy to break.

After being addicted, Li Yu and Li Li left the processing factory at the request of Li An and went to the vegetable greenhouse to pick a few cucumbers to satisfy their hunger.

What Li An didn't expect was that these two little ancestors were not polite to themselves at all, picking up cucumbers one after another, and their arms were full and they didn't stop, and when they saw Li An stop it, they stopped.

As soon as he saw them like this, Li An immediately understood why those ministers would pick their cucumbers regardless of their image, because in this season, there is nothing sold on the market, and the appetite for cucumbers is very good, and picking a few more tastes has become the most normal thought.

At the beginning, the fresh vegetables produced here would be shipped to Chang'an City for sale every day, but since the family members knew that Li An had all kinds of fresh vegetables here, they sent their subordinates to block the city gate every day, as long as the city gate opened, they would go out of the city to stop these vegetables and buy them out, so the vegetables could no longer be transported to the Chang'an City market.

Then, the situation is even more serious, many nobles directly send their subordinates, run to the vegetable greenhouse base, do not sell it and do not leave, this is not to blame these servants scoundrels, if they do not buy a few things back, they will definitely be scolded, and even, there may be a board.

Fortunately, Li An developed 500 acres of vegetable greenhouses in one go, otherwise, it would be difficult for these subordinates who took care of the greenhouses to deal with these rogue aristocratic slaves.

"Have you finished eating so much in one go?"

Ang Lee said angrily.

"Li Shilang, we can't eat cucumbers this season, so we want to pick more."

"Me too, I haven't eaten cucumbers for almost half a year, and I'm hungry for a while, so I ask Li Shilang to forgive me."

When Li An heard this, he immediately smiled, waved his hand and said: "It's okay, I originally asked you to pick it casually, this will blame you, it should be me wrong, you are not wrong, you should grab it when you see a good thing, however, Your Majesty asked you to follow me for a long time, are you still afraid that there will be no cucumbers to eat?" ”

"That's right! Shiro, in the future, we will follow Li Shilang every day, can't we run to pick cucumbers every day? ”

"And what about these cucumbers?"

The two glanced at each other and looked at Ang Lee.

"Cucumbers are only the best when they are fresh, you have picked so many in one go, you must not be able to eat them all, give them to the guards, one for each person."

Li An gave a distribution plan and beckoned dozens of guards to come over and eat cucumbers.

The construction of the annex has been going on for a while, but most of the houses are still not completed, so it is a little inappropriate to live here, in addition, Li Ang was newly married, and he didn't go home last night, and he has to go back today anyway, or he has to suffocate himself to death.

Although Li Yu and Li Li were ordered to follow their own long-term knowledge, there was no need for them to be inseparable for twelve hours, let them go back for one night temporarily, and there was nothing wrong with following them the next day.

"Li Shilang, where will we wait for you tomorrow morning?"

Li Yu asked.

Li An smiled lightly: "You don't have to wait for me, just go here to pick cucumbers, I don't have to arrive when, but you must not enter the processing plant casually, and when I come over, I will take you to see good things." ”

"What's good?"

Li Li asked curiously.

"Keep it secret for the time being, and you'll know when you come tomorrow, go back!"

Li An sold a pass, left with everyone, and returned to Chang'an City.

Xiao Biesheng is newly married, not to mention that Ang Lee and Yan Ruyu were newly married, and after a day of separation, their relationship became even more glue-like.

Li An, who had just returned home, didn't even eat dinner, so he hugged Yan Ruyu to the bed, and rudely pampered him, and after venting his anger, he lazily dressed and had dinner with Yan Ruyu.

After dinner, Li An lay on the warm bed, chatted with Yan Ruyu, told her what he had seen and heard in the past two days, and shared his happiness with her.

When he was about to go to bed, Li An pampered Yan Ruyu again, but this time it was more gentle, which made Yan Ruyu more satisfied.

Li Longji asked Li Yu and Li Yu to follow Li Anchang to see, and this matter quickly spread in the capital, on the surface, this matter seems to be very simple, that is, let the two emperors and grandsons play with Li An, but it is not so simple to think about it carefully.

Everyone knows that Li An is a rare talent in the Tang Empire, and has made a lot of contributions to the Tang Empire, and now, he is wearing many hats and has become a celebrity around Emperor Li Longji, so that Li Yu and Li Yu can follow Li Anchang to see, isn't this clearly telling the courtiers that he is cultivating a successor to his grandchildren?

And this grandchild successor is not one, but two, Li Yu is the eldest son of the crown prince Li Heng, and Li Yu is the son of the prince and the adopted son of King Qing.

Let these two emperors and grandsons follow Li Anchang to see, isn't it clear that the emperor's successor will be the crown prince or King Qing? But whether it is the crown prince or the king of Qing, the ministers are not sure.

Although the crown prince is the legitimate heir, the previous prince Li Ying was not deposed, and he was also killed, and it is really difficult to say whether the current prince can succeed to the throne smoothly.

However, this can at least show that except for the crown prince and King Qing, the other princes have no chance to become the next emperor, and the ministers know this, so they will naturally not bet on other princes.

In just a few days, the situation in the court has changed a lot, many ministers who support other princes have gradually moved closer to the crown prince and King Qing, but they all have room to avoid betting on the wrong treasure, and the power of the prince and King Qing is not very powerful, and the power is still firmly in the hands of Li Longji, so more ministers are not in a hurry to express their positions, and there will be nothing wrong with being loyal to the emperor.

Early the next morning, Li An got up lazily, and after breakfast, he rode his horse in the direction of the other courtyard, knowing that Li Yu and Li Li would be waiting for him there.

Sure enough, the two emperors and grandsons got up earlier than themselves, and when Li An arrived at the courtyard, he saw Li Yu and Li Li, one holding a fresh cucumber in his hand, sitting on the railroad track and nibbling on it, eating with relish.

"Li Shilang, I picked one for you too."

Li Yu and Li Yu stood up and handed a fresh cucumber to Li An's hand.

"It's nice to think of leaving me one."

Li An happily took it, waved his hand, and sat on the railroad track with the two of them to gnaw cucumbers.

"Li Shilang, you said yesterday that there will be good things for us to show today, what is it?"

"That's right! What the hell is a good thing, I didn't sleep well all night last night. ”

Li Yu and Li Yu looked at Li An expectantly.

"Don't worry, I'll take you over to see it when I'm done."

Li An was not in a hurry, eating the cucumbers one by one, and the cucumbers in Li Yu and Li Li's hands had already been eaten, but they had to sit on the railroad tracks and accompany Li An.

Although Ang Lee's identity is not as good as Li Yu and Li Li, Ang Lee is a few years older, and he is a master-level figure, so these two have to listen to Ang Lee.

"Let's go, I'll take you to see the good stuff."

Ang Lee threw away the last remaining cucumber tail and led the two into the processing plant.

"Well, the blast furnace should be built!"

"Li Shilang, we rushed to work last night, and it will be done in the second half of the night, you see, it's okay."

"Good, good, get ready to get started! Bring the two materials I prepared, and add fire to the blast furnace. ”

Ang Lee gave the order fluently and prepared to start making glass.

"Li Shilang, isn't this a blast furnace for ironmaking? We've seen it, and that's what you're talking about. ”

Li Yu and Li Li's eyes showed a look of disappointment.

"That's right, this is indeed a blast furnace, but not a blast furnace for making iron, but a blast furnace for making medicinal jade." (To be continued.) )
