What the?

Your Highness actually asked me to explain to the emperor?

At this time, Su Pengcheng was moved and nervous in his heart.

He didn't understand in his heart that this was His Highness exalting him.

Otherwise, His Royal Highness is the one who knows the most about trains, so why do you have to call him over?

Li Shimin glanced at Su Pengcheng, and then asked Li Su'er casually, "Su'er, who is this?" ”

Li Su smiled and said: "Father, he is the conductor of this Pioneer train, and he is responsible for all the affairs of this Pioneer!" ”

Hearing Li Su's words, Li Shimin nodded slightly and said, "Okay, then you can explain this pioneer to me!" ”

"Yes, Your Majesty."

Next, Su Pengcheng began to explain the Pioneer to Li Shimin and others.

At the beginning, Su Pengcheng was nervous, and his voice was still a little stammering.

Soon, however, the sound returned to normal.

This is a ruthless person who can put life and death out of the way, and his psychological quality is naturally excellent.

With Su Pengcheng's explanation, everyone listened with relish.

What the appearance of the train means to Datang, they can't be clearer in their hearts.

The emergence of the train is an epoch-making reform for Datang.

It is an opportunity for Datang, and after the train and three new crops, Datang will inevitably enter a period of rapid development again.

However, in the crowd, there was one person who was obviously not interested in what Su Pengcheng explained.

This person is naturally the demon king of the mixed world, Cheng Biting Jin.

Cheng Yanjin couldn't help but step forward, slapped Su Pengcheng on the shoulder, and asked with a big grin: "Boy, can you drive a train?" ”

Poof!

Su Pengcheng was directly slapped down by Cheng Biting Jin, and sat on the ground.

Seeing this scene, Cheng Yanjin couldn't help pouting and said, "This body is really weak, how can you open such a big thing with your small body?" ”

Next to Cheng Biting Jin, Wei Chigong couldn't help pouting and said, "Cheng Da fool, you said it yourself, how many ordinary people can afford your slap?" ”

Cheng Yanjin grinned and said hehehe: "I thought that those who could drive trains must not be ordinary people!" By the way, boy, can you drive a train? ”

Su Pengcheng grinned and got up from the ground, quietly narrowed the distance between him and Cheng Yanjin, and then hurriedly said: "Go back, go back to that ......"

It turned out that Su Pengcheng didn't know Cheng Yanjin, and for a while, he didn't know what to call it, so he was stunned.

Li Su couldn't help but step forward and said to him: "Peng Cheng, this is Lu Guogong." ”

Su Pengcheng hurriedly said: "Back to Lu Guogong, the grass people will drive the train." ”

Cheng Yanjin couldn't help but say, "Great! Then you hurry up and start the train and let us see how such a big iron lump runs! ”

Driving a train, but just to let you see?

Su Pengcheng didn't dare to make his own claims, and couldn't help but look at Li Su in embarrassment.

At this time, after Cheng Yanjin said this, those civil and military officials, including Li Shimin, not only did not refuse, but looked very interested.

In fact, it's not just Cheng Biting Jin, they are also very curious, and they also want to see how such a big behemoth runs?

In this, only Li Su is full of black lines.

Huo, do you think of the train as your family's carriage?

When do you want to open it?

Li Su couldn't help but say: "Lu Guogong, it takes a lot of money to start this train once. And every time the train starts, it will cause damage to the life of the train. Therefore, unless it is a normal round-trip transportation, it is not normal to start the train casually. ”

After listening to Li Su's words, Cheng Yanjin couldn't help but ask angrily: "Boy, did you go to Yizhou for a few days and stop taking you Uncle Cheng seriously?" Believe it or not, I pumped you? ”

Li Shimin couldn't help but glared and said: "Lu Guogong, don't mess around!" ”

After watching the train, everyone had an unfinished expression.

And Li Su was taken away directly by Li Shimin.

Now, Li Shimin has too much to ask Li Su.

On the way, Li Shimin couldn't wait to ask: "Su'er, can this train be manufactured in large quantities?" ”

With three new crops, Datang's economy is bound to be greatly improved in just a few years.

With steelmaking technology, Datang was able to build railways.

It doesn't take much, as long as the railways of several main roads are built, then the traffic of the entire Datang will be completely revitalized.

However, Li Su said in embarrassment: "Father, this train is already the result of the best efforts of his sons. Within ten years, I am afraid that a second car will not be built. ”

Now Li Su's loser value is only a few thousand, and if he wants to buy the train again, it is far away.

However, if Li Su really loses with all his might, it is estimated that it will only take a short year or two to buy a train again.

However, Li Su still has more things to buy, and it is impossible to use all the loser value on the train.

With Datang's current scientific and technological capabilities, it will be difficult to make a train if they are given another fifty years.

However, if Li Su continued to buy some advanced instruments from the mall, he would be able to greatly advance the process.

Li Su is not only to teach people to fish, but also to teach people to fish.

The two methods, going hand in hand, can further accelerate the scientific and technological process of Datang.

Listening to Li Su's words, Li Shimin could only sigh regretfully.

In fact, Li Shimin also expected this situation.

This train is so big and so fast, it must be difficult to build.

If it's easy to make, it's wrong.

Immediately after, Li Shimin asked again: "Su'er, the yield of those three new crops per mu has really reached more than 2,000 catties per mu?" What are the land requirements for these three new crops? ”

Compared with the train, this is also a matter of concern to Li Shimin.

Even more so than the trains, these three new crops are concerned.

After all, the core idea of ancient times was to put agriculture first, and they would not put the cart before the horse.

Li Su couldn't help but say: "Father, these three new crops, only sweet potatoes can reach two thousand catties per acre. Of course, if the land is good and the fertilizer can keep up, it is not impossible to get 3,000 catties per acre. ”

"By the way, in fact, where is the child, there is a new type of crop called potatoes, and the yield per mu is almost the same as that of sweet potatoes. These crops can be grown throughout the Tang Dynasty. ”

Hearing Li Su's words, Li Shimin couldn't help but be overjoyed and said: "That's really good! Starting next year, we will make every effort to promote these three new crops within the scope of Datang. By the way, my father heard that you also planted winter wheat in Yizhou, can this winter wheat really work? ”
