Fortunately, Li Yuanji is not unaware of this.

Li Yuanji, who was pulled back to reality by the thinking of these ministers, deeply realized a problem.

It is not easy to completely change a person's mind, and it is not something that can be done overnight.

And real change, the kind of radical change, often takes one, two, or three generations to really do.

And this time span may be 20 years, 40 years, or 60 years.

But Li Yuanji couldn't wait so long, or rather, he couldn't accept the kind of behavior that followed the step-by-step process.

Not because it's not safe enough, quite the opposite, but because it's too safe.

As for whether this kind of ideological emancipation will pose a certain threat to the imperial family, this Li Yuanji has really considered it, and history has given many kinds of references, but it is obvious that the Chinese history that can give him the most reference has not been able to give any answer.

However, judging by several movements in history, the impact on the royal family will certainly be there, but it is more of an impact on power, and it is almost impossible to really affect the status of the royal family.

Because the roots of democracy have not yet appeared in this era, and why should a royal family that can lead them to a better life be overthrown?

Besides, before that, wasn't Li Yuanji also gradually delegating power?

Letting go of some powers that are not particularly important, and grasping those powers that can never be lost, in order to ensure the right to speak of the royal family, for Li Yuanji, this is a very cost-effective deal, one can make himself and his descendants not so tired, two can put more energy on useful places, and three can ensure the status of the royal family.

Therefore, to untie the ideological shackles of these ministers has become Li Yuanji's urgent task at the moment.

So, there are the next ones.

The gathering of these ministers to the proving ground is not just about visiting the train.

The ministers are not as relaxed as Li Yuanji, they are busy every day without touching the ground, and sometimes they can only rest for half a day even on the day off, and then continue to work.

Therefore, if you can find time in your busy schedule, it is naturally impossible to do only this one thing.

And Li Yuanji is also very aware of this, so before that, he ordered someone to make some arrangements in the warehouse of the test site in advance.

It can't be said that it was deliberately arranged, the test site itself has this function, and it is also another scientific research base for the train team, and the research projects here even exceed those of the Academy of Sciences.

Plus the manufacture of trains, modifications, etc., are also done here.

The ministers followed Li Yuanji's pace and slowly walked into the warehouse not far away.

In the quiet warehouse, hundreds of craftsmen are silently making the final preparations, the boiler has been boiling, there is only the continuous sound of gassing, and the machine is not really running.

Everything here seems a bit abrupt, a little surprising, even confusing.

But with previous experience, no one dared to underestimate these strange-looking guys this time.

"Is this going to strike iron? It doesn't seem like it......" Someone saw the name of the name, but then shook their heads, and what they saw now was not quite like what they remembered.

"The Han civilization can develop from scratch to today's point is the result of human efforts, but for hundreds of years, the Han civilization has always stayed at the most developed stage, and it is precisely these that have single-handedly brought the Han civilization to today's human beings, the development of the times, inseparable from the efforts of human beings, but human beings are the biggest stumbling block to the development of the times." Li Yuanji said such an inexplicable sentence.

And this passage not only succeeded in making the ministers confused, but even Li Yuanji's student Ma Zhou also fell into a state of confusion.

No one can understand the intention of Li Yuanji's words, because there are serious inconsistencies in this passage, and even two completely different directions.

But there is no need to question one point, just like Li Yuanji said, human beings can not have what they are today without the efforts of human beings, but why have human beings become a stumbling block to the development of the times? This is something that many people don't understand.

Of course, Li Yuanji is not one of those literary masters, and some questions cannot be expressed clearly, but the meaning is that meaning, although there are some contradictions, but which of those famous sayings and aphorisms in history is not contradictory?

It is precisely because of the contradiction that it has become a famous aphorism.

On the contrary, rather than explaining the meaning of his words to these ministers, Li Yuanji was more keen to tell them with reality and let them understand the meaning of these words for themselves.

Li Yuanji waved his hand, and the officials of the Academy of Sciences were ready again, and directly ordered the craftsmen in front of him to start the demonstration.

A piece of burnt red iron was taken out of the fire, and a huge iron clamp held it tightly.

Then they were placed directly on a strange-looking platform, which resembled an iron table, but with a piece of iron on top, which made it impossible for them to hit it with a hammer.

"What is being demonstrated now is forging a horizontal knife used by the army." The officials of the Academy of Sciences had already received the notice, so they didn't say much at this time, but simply introduced what they were going to do now.

As soon as the words fell, the large iron block above the iron block fell heavily, and the craftsman holding the large iron clamp skillfully swayed back and forth, and after a short effort, when the red color disappeared, the original iron block had become a long strip.

Although this long bar is a little short and a little thick, this efficiency still greatly shocked everyone.

Two skilled craftsmen work non-stop, and it takes half a day to beat a piece of iron into this shape, and how long does it take for a horizontal knife to change from an iron block to a real horizontal knife?

The answer is about ten days, which requires tens of thousands of times of forging and countless times of sharpening, which are all time-consuming and laborious processes.

But before they could fully wake up from the shock, the craftsman replaced the iron block, and then compared the two, the two were basically the same length, the same semi-finished product that was forged once, the only difference was that one needed to be reheated, and the other could be forged directly.

Because it was a demonstration, the ministers didn't have that much time to wait for the warming, so they adopted this mode to forge it.

Under the control of the skilled general, a total of five times of heating process, it took about a cup of tea, and the prototype of a horizontal knife has appeared.

Immediately afterwards, the horizontal knife, which had highlighted its rudimentary shape, was replaced with a horizontal knife that had already been preliminarily corrected, and then handed over to another craftsman, explaining that the correction was not a big problem, but it would waste a certain amount of time, so this step was omitted in the demonstration.

The craftsman simply used a tool to draw a line on it, then placed it on a table, fixed the lower part, and then adjusted the lower position.

Then, the whetstone, which had been transformed into a cylindrical shape, spun around, and a loud noise followed, replaced by a speed visible to the naked eye, and the blade was rapidly forming.

After about half an hour, the roar finally died down, and in its place was a sharp horizontal knife, which could easily cut through an arm-thick wooden stick under the control of the sergeant.

After that, there is a process such as quenching, and there is no need to continue to look at this, and there is no preparation for this cover-up, because everyone knows that the biggest trouble with forging knives is the forging of the prototype and the next sharpening, and the rest can only be regarded as a small problem, which can be carried out in batches, and all the remaining processes add up, and it will not take half a day.

But here, they saw an unbelievable picture in their lives, a horizontal knife from scratch, and it only took half a day to complete?

"Good knives!" Playing with the horizontal knife in his hand that was not really completed, Cheng Zhijie couldn't help but exclaim.

Subsequently, the knife was circulated to other ministers for viewing, and they all had experience playing with knives, so they could also see whether a knife was a good knife or not.

Artificially forged knives, there will inevitably be some problems, such as when sharpening the blade, some places use less force, or a few less grinding, the blade will appear some slight unevenness, although this does not affect the use, the standard equipment is not so harsh requirements, but this is indeed a problem.

But the knife in front of me does not have this problem, the two sides of the entire blade are as smooth as a line, and the sharpness is needless to say.

And most importantly, efficiency.

If a knife opened their eyes, then the demonstration that followed completely conquered these arrogant ministers.

A small pot of molten steel is poured into the grinding tool, and then it runs forward automatically through the rolling iron shaft, and then enters the machine with precision, and when it comes out again, the prototype of a steel bar has already appeared.

In the same way as before, after several stretches back and forth, a round steel bar has been formed.

However, this is not the final ending, after tempering again, the whole is set on the abrasive, and then directly stamped, and when it appears in front of everyone, a round steel bar becomes rebar.

The method may be a bit old-fashioned, but after the final tempering and quenching treatment, its quality is not too much of a problem.

Anyway, if we don't build those high-rise buildings with dozens or hundreds of floors, this kind of quality is already the best.

Before that, the steel bar was stretched out by manpower, yes, pure manpower, which was far more time-consuming and laborious than iron forging, and the output was also a problem.

But now, except for a few people who operated the machine and those who were waiting to carry it, there were no large piles of coolies waiting to be stretched.

It is no exaggeration to say that it surpasses manpower by a hundred times in terms of quality and efficiency.

"The output is frighteningly high, saving time, effort, and worry, just like a train, as long as the cause of the failure is determined, all that needs to be done is to replace the same part, and then it can continue to drive, unified standards, so that any component can be used in the same part of any machine, do you know what is industrialization? This is industrialization, a steam engine, which brings not only the train, but the progress of the whole society......"
