Li Jing recently liked the days when he went to the Tang Royal Military Academy to teach.

There is no need to consider disputes in the court, and there is no need to intrigue, as long as you pass on your experience to the students.

In the past, Li Jing was very cautious about accepting apprentices.

Because the meaning behind accepting apprentices is completely different from taking classes in a college.

Those who are qualified to become their own apprentices will inevitably make achievements in the army.

Originally, his influence in the army was very huge, and many generals in the DPRK and China had a bad relationship with him, so if he accepted apprentices on a large scale......

Maybe at some point someone will be falsely accused of bad intentions.

However, Li Jing actually hopes that what he has learned can be passed on.

None of his two sons are angry, he just wants to teach, and others don't want to learn.

is also a Su Dingfang, who can barely be regarded as having his true biography.

"County Cheng, Da Lang is now in Guanshishan Academy, he hasn't come back for two months, I heard that he has been hanging out with the people of Gewu Academy all day long, do you want me to call him back?"

Mao Laosi slipped back from outside like a cat.

As Li Jing's descendant, Mao Laosi has been by Li Jing's side since he was a county magistrate in Mayi.

Therefore, Li Jing will not shy away from Mao Laosi for many things in the Weiguo Mansion.

Mao Laosi, who has never been married and has no family, has not lived up to Li Jing's trust, and completely takes the Weiguo Mansion as his home.

"Forget it, it's better for him to hang out with the people of Guanshishan Academy than to follow His Royal Highness the Crown Prince every day, right?"

Talking to Mao Laosi, Li Jing didn't shy away from it so much.

For a long time, as Li Jing's eldest son, Li Desai can be said to have broken Li Jing's heart.

It stands to reason that Li Jing loves him very much when he has a son in his later years.

However, since he was a child, he was not interested in swords, and he couldn't read books on the art of war.

Li Jing tried various methods, but in the end there was no effect, so he accepted his fate.

However, things that worried Li Jing even more came.

After Li Shimin ascended the throne, he quickly appointed Li Chengqian as the crown prince, but few ministers of the DPRK and China did not take sides.

However, Li Desai was very close to Li Chengqian, and followed Li Chengqian's ass at every turn, and many people thought that Li Jing was a staunch princeling.

In fact, Li Jing is not a party at all.

If you have to say what kind of party he is, then he is a royalist.

Whoever is today, he Li Jing will support whomever he wants.

As for the various rivalries between the princes, he was not interested in it at all.

"This is also true, now that the struggle between the East Palace and the Wei Wangfu is becoming more and more intense, it is a good thing that Da Lang can avoid this limelight in the Guanshishan Academy."

Mao Laosi is not stupid, otherwise Li Jing would not have given him many things to do.

"What about Jiro? What kind of downwind dart game did he make, I heard that there is a shadow of the Chu Wangfu behind it? ”

Li Jing sighed, feeling that none of his two sons had any peace of mind.

He is a dignified Duke of Weiguo, and his second son actually yearns to become a ranger.

It was said that he was still thinking about traveling the world and making Li Jing depressed enough.

So a while ago, he was going to engage in a tailwind dart game, but Li Jing actually held back and didn't interfere.

"Erlang's downwind dart game is very popular, and it has attracted some noble children to partner. There are also many businessmen in the east and west cities who began to look for them to escort darts, among which the Datang Royal Money Village entrusted the escort task from Chang'an to Liangzhou to the Shunfeng Dart Bureau. I actually saw that the business of Shunfeng Dart Bureau was very prosperous, and someone in Chang'an City recently set up several Dart Bureaus. ”

Mao Laosi showed a relieved smile on his face.

Although at the beginning, he didn't approve of the downwind dart game.

But looking at the current appearance, this is also a serious job.

Even the Datang Royal Money House has already recognized them, which is equivalent to being officially recognized.

It's much more reliable than being a ranger.

Don't look at Datang, there are still many rangers walking in the world now, but in fact, there is not much room for survival.

In troubled times, the rangers who act chivalrous, eat meat, and drink wine are the lives of many people with martial arts.

However, these people are, in a sense, a destabilizing factor in a society.

Any great unified dynasty would not allow a large number of rangers to exist, let alone allow them to set up a private torture hall and act chivalrous and righteous there without going through the official trial.

Therefore, the original dream of the Li De Award was actually not supported by anyone.

Even Li Desai, who has unreliable intentions, does not support his younger brother's idea.

"His Royal Highness the King of Chu is doing things, and now it is becoming more and more incomprehensible. However, in the matter of Da Lang and Erlang, our family still owes him a favor. ”

Li Jing sighed and stopped thinking about these troubles.

……

Guanshishan Academy has never stopped the pace of construction.

As the number of students increases every year and various research institutes are established, the number of buildings in the seowon has become more and more numerous.

In a relatively simple house, with a style of red bricks and green tiles that is obviously different from the surrounding courtyards, a group of people are busy.

This is the steam engine research institute of Guanshishan Academy.

"Huaiying, are you sure that the drawings given by the prince are like this? How do you feel that the steam engine made has no effect at all? ”

Li Desai looked at the strange-looking big pimple in front of him and was a little discouraged.

In the past few months, Li Desai has basically spent time in the steam engine research institute.

In the face of some sketches given by Li Kuan at the beginning, he followed a group of students and craftsmen to make the current sample one by one.

Who knows, after the sample is made, the water in the boiler can boil normally, and the other parts have no reaction at all.

According to the vision described by Li Kuan before, the steam engine can be used to propel some machinery, crush coal mines, crush papermaking materials, and even be used as the power of equipment to process parts.

But the sample in front of me and the vision described by Li Kuan have nothing to do with it.

"Brother Li, the drawings given by my master are just a schematic diagram, the samples we have made now are motionless, the biggest possibility is that there is a problem with the connection mechanism inside, otherwise there would be no movement."

Di Renjie also couldn't understand what the situation was now.

At the beginning, Li Kuan told him that the research and development of the steam engine was not so easy, and it would be ideal to be able to come up with a product within three years.

At that time, Di Renjie didn't think so, and thought about getting a usable steam engine out this year.

As a result, I have been tossing for a long time now, and I finally tossed a sample, but it seems to be useless at all.

It seems that I underestimated the difficulty of the steam engine.

"His Royal Highness the King of Chu just told us briefly about the working principle of the steam engine, and no one knows whether the setting of this connection mechanism is reasonable or not. However, the application of the steam engine has such a broad prospect, and the academy has allocated so much money for us to study, but we have not made any progress, and I am a little anxious. ”

Li Desai pursed his lips and thought about what to do.

Although he only came to the Gewu Academy of Guanshishan Academy last year, Li Desai's skills are not bad, and he is even a few points better than most of the students of Guanshishan Academy.

Compared with other students in the academy, Li Desai's hands-on ability is obviously a few points stronger.

"Master said that it is very time-consuming and laborious to develop a mature steam engine, and I think the steam engine research institute can cooperate with the mechanical workshop to re-study the current samples together, see what went wrong, and then improve it step by step."

Di Renjie felt that his master's original instructions should not be groundless.

Since the master has said that it is ideal to be able to do it in three years, then I still have a correct understanding and gather more resources to do it in a down-to-earth manner.

"That's all it takes, it seems that this steam engine is more difficult to make than we thought. Huaiying, His Royal Highness the King of Chu said that the steam engine can completely change the living conditions of the people in the Tang Dynasty, will you say that this statement is too exaggerated? ”

Li Desai is now focused on the Steam Engine Research Institute.

As for the prospects of the steam engine, it is natural to be more concerned than anyone else.

He is a future prince, like a craftsman, in the research institute buried in the hard work, in addition to the deep love of craft research, the most important thing is the research of the steam engine is expected to make himself famous in history.

It may be difficult for later generations to understand how attractive the history is to the ancients.

Especially for people who have no worries about food and clothing, this kind of thing is more desirable than anything else.

"It's hard to say, although it sounds a bit exaggerated, but Master's words are always based on evidence. If this steam engine can really make the processing of items in various workshops fast and simple, and can provide power for various equipment, and can even be installed on a four-wheeled carriage, so that the carriage can walk without horses, then it can really completely change the lives of the people of the Tang Dynasty. ”

Di Renjie was in the courtyard of the Chu Palace, and he didn't listen to some unbelievable stories of General Li Kuan.

So he has a higher level of acceptance of many things than others.

"Well, but I don't really have a clue how to make this steam work. Why don't we ask His Royal Highness the King of Chu to come over and see if he can give us some advice? ”

Li Desai listened to Di Renjie's words and was very moved.

The greater the role of the steam engine, the greater the effect on the fame of the inventor.

Since he was a child, Li Desai likes to study all kinds of "strange and obscene techniques", and I don't know how many times he has been secretly laughed at.

Li Jing has no special pursuits in the court, and it has something to do with the fact that his two sons are not very competitive.

Li Desai really hopes that everyone in the world will see that his strange and obscene skills are not useless.

"Okay, I'll go back and mention to Master that he has always been very concerned about the steam engine, and he should be willing to come and take a look."

For others, it may not be an easy thing to move Li Kuan.

But for Di Renjie, it was a gesture.

……

In the East Palace, the eldest grandson Jiaqing reported to Li Chengqian some information that had been collected.

"That Li Dejian, he asked him to come over for the banquet several times in a row, but he didn't participate, could it be that he saw the wrong direction of the wind and took refuge in Li Tai's side?"

Li Dejian is a figure that Li Chengqian focuses on wooing.

As Li Jing's eldest son, Li Dejian stands on Li Chengqian's side, and in the eyes of many people, he supports the current crown prince on behalf of Li Jing.

"His Royal Highness the Prince, this Li Dejian doesn't know what evil he has fallen for recently, and he actually went to Guanshishan Academy in a good manner. He doesn't look at himself in the mirror, his daughter is already five years old, and she still goes to the academy to be a student. ”

The eldest grandson Jiaqing naturally felt Li Chengqian's dissatisfaction with Li Dejian, and he spoke as he liked, very politely.

"As a student at Guanshishan Academy, it won't be that you don't come to the banquet every time. Have you been to him? ”

"I looked for it, but I didn't see it. It is said that he is now soaking in the steam engine research institute of Guanshishan Academy all day long, and there is a special guard at the entrance of this research institute, and no one is allowed to enter casually. I went to look for it twice, but I didn't see Li Dejian in person. His Royal Highness the Prince, according to me, this Li Dejian, as the eldest son of the Duke of Weiguo, did not go to the army, but mixed with a group of craftsmen all day long, and now nine times out of ten he is also fascinated by some new craftsmanship, not necessarily for other purposes. ”

Eldest Sun Jiaqing's words, even he didn't believe it.

"My cheap second brother always spoils my good deeds. I won't talk about my position if I don't know it, and now I have to dismantle my platform. Hmph, does he really think I'm a bully? Do you really think that no one in Chang'an City can move him? ”

Li Chengqian was criticized by Li Shimin again today, but Li Tai was praised by Li Shimin for completing the manuscript of the editor-in-chief's "Chronicles of the Territory."

This book, edited by Li Tai, sorts out the history, geographical outlook, names, mountains, rivers, cities, historic sites, myths and legends, and major historical events of the main prefectures and counties in the Tang Dynasty.

Due to the relatively large editorial team and the abundance of talents, the whole book can be said to be a sideshow.

If Li Shimin got the treasure, he not only collected this work into the library in the Daming Palace for preservation, but also gave Li Tai many rewards one after another, making Li Chengqian's eyes red.

No wonder he was in a very bad mood today.

"His Royal Highness the Prince, my subordinates think that His Royal Highness the King of Han has a sentence that is more correct."

"That sentence?"

"The first strike is strong, and the second strike suffers!"

The eldest grandson Jiaqing looked at Li Chengqian with deep meaning.

This Royal Highness the Crown Prince is so similar to the original Prince Yin.

A lot of the time is indecisive, but there is a capable younger brother.

Everyone has already seen the consequences of not doing it first.

As a die-hard supporter of Li Chengqian, the eldest grandson Jiaqing still expects to rely on the power of Conglong and sit in the position of the six Shangshu.

"Let me think again!"

Li Chengqian's face was cloudy, and he kept thinking about the pros and cons of things in his heart.

Although the current situation is not very good, the queen mother still supports her wholeheartedly.

So it's hard for him to make up his mind.
