"Owner, we have completed all the manufacturing tasks you arranged, you see?" "Okay, I'll go right away."

Excited, Yang Heng even trembled with excitement all over his body, to know the Dao, since he crossed the Dao, it was the first time he was so excited.

Train, this is the biggest project he has ever had in this era, once this project is successful, the sky of the Tang Dynasty will slowly change, but not for the worse, but in a sunny direction, and even to the point of developing to the point where the wind is going to be windy and rainy.

Trains, railways, involved in nature is transportation, although communications, electricity, are very important, but at the beginning of development, even at any stage, this transportation is the top priority, or how in the previous life there was that slogan is, if you want to get rich, first build roads, this road is involved in many ways, a, in the military, it can make the army, or military materials with the fastest speed to transport to the place that needs to be transported.

In terms of economic construction, it can quickly spread out the goods, without the need to use a lot of manpower, material resources and even animal power to engage in transportation.

It is used in disaster relief, it can transport disaster relief materials to the disaster area in a timely manner, and can ensure that most people survive.

"What, you said Xuewen was assembling the so-called locomotive, did you see it clearly?" "Yes, Your Majesty, the intelligence officers under the minister found from afar that even the horse was also at the scene in person, and the voice was also much louder, obviously, he was very excited, and this action was unprecedented, and even this assembly was carried out on the railway, according to the minister's estimate, that thing should be very large. It's heavy. That's the locomotive, of course. This is the only thing that needs to be assembled on the railway, and the ministers have not seen them make carriages before, although the carriages are also done on the railway, but those things, the horses will not be on the scene. ”

Why do you look from a distance instead of looking closely, because Yang Heng has isolated all the intelligence officers in a far away, and if there is anything special that needs to be kept secret, he will arrest the intelligence officers nearby. Even Li Er's people can't succeed, since Li Er's pit Yang Heng last time, his intelligence officers are also unable to move an inch in the Yang family.

"Well, I'm going to go to the scene now." Li Er was in a hurry, he was also excited, he naturally needed to take a good look at this thing that traveled a thousand times a day and eight hundred nights, this was something he couldn't even think of.

"Your Majesty, the minister thinks it's better for you to wait for the horse to invite, the minister thought. Once they have succeeded in making it, the colt cannot but come and invite His Majesty to come and go down to you. If His Majesty goes down now, then if they don't succeed, won't His Majesty be disappointed? ”

"Your Majesty, the concubine also thinks so, let's wait for Xuewen to invite, those two stinky girls, I don't know how to come back and say, it's okay to say that Changle married out of Lu, isn't Yuzhang still married out of Lu."

"Sneeze, sneeze." "Who is talking about me, it must be the queen mother, since the last time we saw the queen mother, we have never entered the palace again, it seems that the queen mother has an opinion." "Yes, sister, I think we should also go back to see our father and mother."

Not to mention the matter of Changle and Yuzhang, just talking about Yang Heng, at this time he was directing everyone to install the steam engine on a car chassis that had been made a long time ago, could it be said that Yang Heng was so confident that he could use it after the installation was completed.

Although this multi-cylinder steam engine has not been tested, it has also undergone a large number of model tests and even calculations, and then the final drawings and parts began to be made.

In short, this primitive steam-powered locomotive still has to be classified in the range of rough products, and the required efficiency is not so high, and the energy consumption is not particularly need to be saved, if you take an analogy, that is, people have entered a rich rich gold mine, their current goal is to pick up the good things first, and those poor mines, no one really can afford to look down on them, naturally, in the later stage, it is necessary to consider the poor mines, the refining of poor mines, naturally need more refined technology, although this metaphor is a little off-topic, But that's pretty much it.

And these things that Yang Heng is manufacturing now, except for the need for precision in chemistry, the others are not particularly demanding, such as this steam locomotive, first of all, there is no requirement for iron consumption and coal consumption, that is, it can be as powerful as possible, so that if you think it is not safe, you can pile up more iron, the combustion value is not enough, you can burn more coal, and the speed and requirements are not very fast.

There are also generators manufactured before, although there is no qualified silicon steel, but ordinary iron sheets can also conduct magnetism, that is, the magnetic permeability is small, and it can also generate electricity, that is, the generator needs to be as large as possible, and the loss is larger, as long as it can generate electricity, low loss, high permeability silicon steel sheets, and even other conductors will also appear.

What, the resources are exhausted, this is in ancient times, alas, but there are no big energy consumers, what are you afraid of consuming more resources, besides, the finished product has not even gone through the test stage, I don't know how many resources have been saved, so these are not a matter in Yang Heng's eyes, as long as things can be manufactured, they can be used, use this rough thing, create a huge profit, and then use these earned profits to slowly transform some things, isn't it getting better and better.

"It's almost done, Guanyin, you help me think about it, which direction will this railway be built first, or else, we will destroy Goguryeo first, you must know the Dao, this is a thorn in my heart, back then, Guangke three expeditions to Goguryeo, but it was not successful, and the most powerful national power was also consumed on this."

"Erlang, this, the concubine doesn't understand, you'd better discuss with the ministers, or you can discuss it with Xuewen, the concubine thinks, he may understand these things, after all, this railway is organizing and building." The eldest grandson said softly, this is what she really can't say, if a few years ago, the eldest grandson might have persuaded Li Er not to think about this, but now, the national strength of the Tang Dynasty is thriving, and has even reached an unprecedented height.

However, the national strength of the Tang Dynasty has gone up, but Li Er's confidence has not kept up, so he is a little hesitant.

If you ask Yang Heng, Yang Heng's first thought is to oppose, but if you think about it carefully, it is not an objection, at this time, Datang is already invincible on the earth, although the steamship does not have an idea in anyone's heart, but after that thing is successfully manufactured in the train, will the steamship be late.

"Report to the owner, the steam locomotive is all assembled." "Okay, organize people to conduct two inspections, if there is nothing missing, then ignite, test the car, by the way, this is a historical moment, you check, check a few more times, I will go and ask His Majesty to come down and light the fire on the spot."

Suddenly, Yang Heng remembered. Such a big event, this ignition can't be carried out easily, you must invite Li Er to come, otherwise, Li Er should be unhappy, so it is normal to check a few more times, otherwise, when Li Er ignites the fire, the train can't run, isn't that a joke, and this Li Er can't be invited.

"Your Majesty, here, here, here, here the horse." "Cheng, this kid is considered to be intellectual, pass the word, let Xuewen come to see me directly." "Your Majesty, please ask Your Majesty to personally light the new train tomorrow, the minister has already asked Yuan Daochang before coming, tomorrow is an auspicious day for the zodiac, and you can do everything."

Well, Lao Yuan can also fool, and the phrase "everything is good" has come out. "Really, that's what Daochang Yuan said, good for everything?" In fact, Li Er was also a little worried in his heart, if he went and couldn't ignite the fire, wouldn't it be a loss of face, if he let others light the fire, it would be okay if he didn't succeed, if he succeeded, it would also be a loss of face, such a big thing, he Li Er didn't arrive. Therefore, Li Ercai paid special attention to Yuan Tiangang's words.

"Xuewen, tell me, can tomorrow's ignition really succeed?" "Don't worry, Your Majesty, tomorrow will be 100% successful, even if you don't succeed."

"Well, I have decided, I will go tomorrow, not only I will go, but even the officials of the whole court will go, and even the people of Chang'an will also go to the scene, I need this sensational effect." Li Er suddenly made up his mind, if he wants to move, then move a big one. (To be continued......)
