While the shipyard encountered problems, Lao Xu also encountered the same problems in Chang'an.

After the small steam engine was scaled up and placed on railroad tracks, the biggest problem arose.

The air leakage was severe, and as a result, there was a lack of power.

Originally, according to estimates, such a large steam engine could easily pull more than ten carriages, but as a result, the speed plummeted after only five cars, and it was not even as strong as a pack horse.

The carriage was newly manufactured, not the same horse-drawn carriage body as previously tested, and a carriage was ten paces long and three steps wide, all made of steel, and its own weight was not a small amount.

And in the face of such a large weight, the front of the car will naturally lie on its stomach.

After thinking of countless ways and conducting countless tests, the results were either impossible, or they were washed away by air pressure after not running for a long time, resulting in steam leakage and a plummeting power.

The cylinder directly drives the wheel to rotate, and with the alternation of hot and cold gases, the power shaft is also constantly moving, not fixed, which brings a huge problem to the sealing.

In this regard, Li Yuanji has no better way, because he doesn't understand it, so he can only wait for the scientific researchers to solve it little by little.

The role of the train is self-evident, and for Datang, both economic and military, it is indispensable.

The steam leakage of the train steam engine is actually not fundamentally different from the water ingress of the ship, as long as one of the two problems is solved, the other will naturally be solved.

"Your Majesty, the Tibetan problem has been basically solved, the policy of the imperial court is very popular over there, and more serfs are willing to accept the governance of the Tang Dynasty, although some serf owners are unwilling, but under the suppression of General Su, the arrogance that has just begun has been suppressed, and the effect is surprisingly good, and now General Su does not even need to send out a large number of scouts to investigate, and many serf owners' every move will be reported by serfs." Fang Xuanling reported on the recent work as always.

The emperor is lazy? In a way, Li Yuanji, the emperor, is indeed quite lazy.

He was in power for only four days a month, a court meeting on the first day of the new year, and a cabinet meeting three times a month.

Except for these four days, Li Yuanji rarely participates in political affairs, but Li Yuanji's power and prestige have not decreased because of this, but have been further strengthened.

Of course, the rest of the time does not care about political affairs, it does not mean that you do not worry about political affairs, the board of supervisors will report the latest situation directly to the emperor from time to time, how many eyeliners are there in the court? No one knows this, but what is certain is that the entire court is under Li Yuanji's sight, even if he has lazy behavior, he still knows the entire court well.

In addition to these two channels, as the head of the cabinet, Fang Xuanling can report anything he feels important to the emperor at any time, and as long as Fang Xuanling reports, Li Yuanji will also give instructions.

But even so, Li Yuanji's free time is still about half a month every month.

In this regard, Fang Xuanling could only express his helplessness while continuing to work hard.

continued: "He Xin is still on the way to Tubo, but according to the feedback back, the result is not very good, even if he stays in Junzhou all the year round, the geographical environment of Tubo still brings great difficulties to He Xin, so they can only move forward slowly, if they are slightly uncomfortable, they have to stop to rest, whether they can go this year is still a problem." In addition, the garrison also needs to be considered, although General Su did a good job, but it is not suitable for guarding in Tibet. ”

"The situation in Tubo is different from other places, it is normal to feel unwell, even if I go with you, the result may not be better than He Xin, and Tubo has settled down for the time being, what is needed next is a long combing, there is no need to rush this moment." Li Yuanji shook his head, and undoubtedly chose to support He Xin.

It's not because He Xin has anything to do with him, but in this matter, Li Yuanji's heart is very angry.

The civil and military forces of the Manchu Dynasty shirked for half a year, but they still failed to find a suitable candidate.

Is there really no one? There are people, there are not one or two suitable people, but everyone thinks that Tubo is a place where birds don't, even if the army goes, they have to train two years in advance, but Su Dingfang's side has not had two years, but they have also stayed in Tuyuhun for a few months.

Everyone knows that the environment in Tibet is harsh, and there is almost no understanding of it, no one wants to go, and no one is willing to give up the prosperous life and future of Chang'an.

Even if he issued an edict, there were very few responders, and at this time, even those who were depressed and could only talk about it were worth cultivating in Li Yuanji's opinion.

It is precisely for this reason that Li Yuanji directly designated the metropolitan governor of Gaoshan Prefecture as a metropolitan governor from the second grade, a metropolitan governor from the second grade, even if the location is in the middle of nowhere, even if it is not as good as other places, but now no one dares to say that the future of this metropolitan governor is not good.

Envy? It's late......

The sour taste in Li Yuanji's words, how could Fang Xuanling not hear it?

But what if you hear it? What could he do?

No matter how good he is, he is just a courtier, and there are some things that he can't call the shots at all.

Moreover, Li Yuanji's character is also very clear, as long as it is something he recognizes, he doesn't want to pull him back.

Of course, before that, Li Yuanji's decision was rarely missed.

It is precisely because of this that in the face of the gold-swallowing beast of the Academy of Sciences, even when the finances are so tight now, the ministers do not dare to reduce the budget of the Academy of Sciences at will.

People outside may only see that the Academy of Sciences is a bottomless pit, and they can't see how much money needs to be invested to satisfy them, but as a minister, who doesn't know the importance of the Academy of Sciences?

It can be said that the Academy of Sciences is the real core of Datang.

An emperor who has excellent performance in many aspects such as military, economy, science and technology, people's livelihood, etc., even if he is not usually strong, but in front of such an emperor, who can not have pressure?

Is the emperor's close minister really that good?

Who can see the bitterness behind the scenery in front of people?

"I don't know what arrangements Your Majesty has for the garrison in Gaoshan Prefecture? He set out to arrange some other things. Fang Xuanling once again brought up the issue of the garrison.

The garrison is important, everyone knows it, but in the Alpine state, the situation is different.

In other words, after Li Yuanji took the throne and after the reform of the military system, the rules of the entire Tang Dynasty have changed.

Although there were signs of change as early as the Li Yuan period, the speed of change at that time was very slow, and it can even be said that it was stagnant.

Originally, Li Shimin wanted to completely promote this improvement by streamlining the imperial court, and did a lot of preparatory work in the early stage, but it turned out that all this was cheaper than Li Yuanji.

Of course, it can't be said who is cheaper, Li Shimin has done a lot of preparations, but it is not as fine as Li Yuanji.

Now there is a separation of the military and the government, and all localities are supervising the history or something, and only the administrative power is left in their hands, but there is no military power.

Military power is not in the hands of a certain person, but in the hands of the Ministry of War, of course, Li Yuanji has mentioned before that this is only a temporary change, and there will be refined changes later, and the next time is the final freeze-frame version.

Li Yuanji squinted his eyes slightly, obviously he had already seen Fang Xuanling's purpose in his heart, whether the concern was false or not, and the recommendation was true.

"Tell me about the person you like!"

"As a civil official, how dare a minister express his opinion on such a matter? The reason why the minister asked His Majesty was mainly because he was thinking that the budget for the next year was about to begin, didn't His Majesty say that he would have a banquet for them when those soldiers came back? Therefore, the minister wanted to calculate first and see how to prepare for this matter. Li Yuanji asked him about the candidate in a friendly voice, but Fang Xuanling was frightened and a cold sweat broke out on his back.

Don't look at Li Yuanji's smile on his face, which is harmless to humans and animals, you can see Fang Xuanling's understanding of him, as long as he says the name of this person, even if the person the emperor originally thought of was him, he would never send him in the end.

What Li Yuanji hates the most is those who follow crooked ways.

There are skills that can be taken out in a dignified manner, and some skills can be used, but they must not be the kind of skills that cannot be seen.

Fang Xuanling also felt that he was a little careless, and almost lost himself, but fortunately, his head turned relatively fast and he was broken back in time.

But no matter how much it is broken, how can the emperor not see this?

"Go back and tell him, don't think that if you don't say some things, I won't know, it's impossible to go to Gaoshan Prefecture, I won't kill him, thank God, I dare to think about anything else, do you really think that I don't dare to kill the killer?" Li Yuanji has been waiting, waiting for someone to come.

Originally, he thought that this person would be Zhang Liang or someone else, but what Li Yuanji didn't expect was that this person turned out to be Fang Xuanling.

From the time he mentioned the garrison in Gaoshan Prefecture, Li Yuanji had already vaguely guessed something, although in the end he still didn't speak, but twice he wanted to talk and stopped, and finally forcibly pulled to other places, standing in the position of the emperor, well-informed, how could he not see this?

"The minister knows the guilt...... Fang Xuanling secretly cried out bitterly in his heart, but his face could only respond again and again.

He hadn't forgotten that the wall had ears, but he still hadn't figured it out, how did the emperor know?

Of course, Li Yuanji didn't actually know, he only knew that Fang Xuanling went to see Hou Junji, and soon after he came to him to mention the matter of the garrison in Gaoshan Prefecture, with the cause and result, what was the process, does it matter?

What did Hou Junji do, didn't he know himself?
