The two hurriedly stood up and saluted Comrade Li Er to receive the order, and Wang Ke wanted to turn around and leave after Comrade Li Er told them to "excuse themselves".

When Comrade Li Er saw that Wang Ke was leaving, he hurriedly stopped him and said, "Boy, you haven't told me about the car yet, now that the business has been finished, it's time to tell me what the car is all about!" ”

Wang Ke, who was already facing away from Comrade Li Er, looked at the sky outside the house that had gradually darkened, and now he really wanted to run out immediately.

But this Comrade Li Er had already stopped himself, and it was already impossible to run, so he had to reluctantly turn around, squeeze out a little smile on his face, and said to Comrade Li Er: "Your Majesty, don't you say okay today?" It's already dark this day, and the emperor should have dinner. ”

Wang Ke seemed to be thinking about Comrade Li Er's words, but in fact he was already hungry and wanted to rush home for dinner, but he couldn't say this directly in front of Comrade Li Er, so he had to say that he was thinking about Comrade Li Er, and he couldn't let Comrade Li Er talk about things hungry.

But Comrade Li Er didn't accept this feeling, and said with a glare: "What's the urgency of eating!" Now you explain the matter of this car to me first, if you don't say it, you don't want to go back today, just stay here, I and Ke'er are eating while waiting for you to tell me about it. ”

Comrade Li Er's trick is ruthless enough, if Wang Ke doesn't say it, not only will he not let Wang Ke go home, but he will also let Wang Ke watch him and Li Ke eat, now Wang Ke is already hungry, and let him watch Comrade Li Er and Li Ke eat, it will be really uncomfortable. \\**

But Li Ke didn't have long eyes, and also said to Wang Ke on the side: "Brother Wang, just say it quickly, not only my father wants to know, but even I want to hear Brother Wang talk about it!" ”

Li Ke didn't speak and nothing, Wang Ke just said that Comrade Li Er's belly lawsuit in the stomach was forgotten, but Li Ke made this sound, Wang Ke was a little unhappy, this matter was originally provoked by Li Ke, if Li Ke didn't ask himself in front of Comrade Li Er, there would be no such thing, now it's good, I'm so hungry that I can't do it, these two fathers and sons don't want to let them go.

Thinking about it, Wang Ke wanted to scold Li Ke a few words and vent his grievances in his heart, but in front of Comrade Li Er, Wang Ke really didn't dare to be so presumptuous, so he had to glared at Li Ke fiercely, and scared Li Ke so much that he didn't dare to say anything anymore.

Of course, Comrade Li Er's actions of Wang Ke saw it, but he also knew that the relationship between Wang Ke and Li Ke was very good, and it was harmless to make trouble between the two of them, so he smiled and didn't speak, just looked at Wang Ke to see if he could say it.

To tell the truth, what Wang Ke saw in later generations is already a mechanically driven car, this wooden car is the two-wheeled rickshaw he saw when he was a child, to say that these four-wheeled cars, he really hasn't seen it with his own eyes, as for he knows that there is, but he has only seen it in history books and later generations of movies and television, when did this kind of four-wheeled car appear, Wang Ke no longer remembers, now I want Wang Ke to talk about it, Wang Ke really has to think about it before he can say it.

Comrade Li Er has already spoken, if Wang Ke doesn't say no, he has to try to recall the appearance of the four-wheeled carriage he knows, Wang Ke said: "Your Majesty, this thing is like this, now all the cars I pull are two-wheeled, the speed of travel will not be very fast, and it is more troublesome to set the car and unload the car, if this car can be changed to a four-wheeled one, the speed of running will be much faster, plus now I am also rebuilding the road, and the road surface is much better than before, This four-wheeled carriage is much faster than a two-wheeled one, even if it were to walk on dirt roads, and if I looked at the current road, it would run much faster. ”

After listening to Wang Ke's words, Comrade Li Er frowned, he had already heard it, Wang Ke was talking about a four-wheeled carriage, that is to say, this kind of carriage is pulled by horses, and now in the people, it is just an ox cart, if it is changed to a four-wheeled carriage, then it means that they have to be pulled by horses, but where did this horse come from, there are not so many horses now!

Comrade Li Er said the doubts in his heart, at this time, Li Ke generally can't speak, but at this time he also made an exception to open his mouth, and echoed Comrade Li Er's thoughts, for them, for this horse, but very favorable, and the Turkic years of fighting, let them know that this steppe people can come and go like flying, the most fundamental reason is because of the existence of horses, with horses, they can come and go freely, and time is also 'spent' and less expensive.

The Central Plains region where Datang is located has always been short of horses, and self-produced horses either have endurance but no speed, some have speed but no endurance, and cannot travel long distances, only Turkic horses from the grassland, both of which have both advantages, and are really rare good horses.

But it has always been, the Central Plains has been farming-based, horse breeding is a big problem, military horses have always been purchased from the Turks, if the Turks do not want to go to the Central Plains of various daily necessities, it is estimated that for their own interests, they are not willing to use horses to trade with the Tang Dynasty.

It's just that the current situation is quite different from before, Datang's campaign against the Eastern Turks has given Datang a source of Turkic horses, although the Turks living in this land are still nomadic, but for Datang to get horses, there is no longer as difficult as before, Wang Ke knows this deeply, which has become an important basis for him to dare to say the four-wheeled carriage.

Wang Ke explained his analysis to Comrade Li Er in detail, and immediately let Comrade Li Er understand, for Comrade Li Er, don't look at the Eastern Turks have been defeated for a short time, but in their minds, they still haven't really included this land in the territory of the Tang Dynasty, and they still habitually think that this place is still occupied by the Turks.

As for the ox cart used by the people, Wang Ke has never thought about this problem, cattle are indispensable for farmers to cultivate, and when there are things to be transported, it is normal to use cattle to pull the cart, if the people have to change for this, it will be meaningless at all.

As for whether to use four wheels or two wheels, it can completely depend on the preferences of the people themselves, and these two models can also coexist forever.

Now the four-wheeled carriage that Wang Ke talked about was purely considered from a military point of view, and he only considered the speed of replenishment and delivery of military supplies during the march, and did not consider the civilian aspect at all.

Comrade Li Er still agreed with Wang Ke's explanation, but as soon as Comrade Li Er talked about the car, he always had a question in his heart, and now he couldn't help it more and more, and finally asked Wang Ke: "Boy, can't you let me build a car like yours?" ”

Comrade Li Er's words made Wang Ke sweat profusely, why don't you want to, but you have to be able to build it, now you can't reach any technology, and no one will do this, except for driving, if it breaks somewhere, it is estimated that you can only look at it, and you can't move anything, if you want to build a car, it's completely fantastical.

As soon as Comrade Li Er saw himself asking this, Wang Ke immediately turned into a bitter face, I don't know what was going on, in his opinion, Wang Ke knows everything, and there are many things he doesn't know, he also understands, how could he talk about this by himself, Wang Ke will be like this immediately?

Wang Ke said a little short of breath: "Your Majesty, this minister really doesn't know at all, don't look at the minister can drive, but the structure of this car is too complicated, and the minister can't 'get' it, and now many of the technologies of my dynasty may not be able to reach it, if you want to build a car like the minister, it will take a long time to think about it." Now it makes sense to start by improving the existing two-wheelers. ”

Li Ke didn't speak on the side, but he was convinced of Wang Ke's words, he was the person who took Wang Ke's car the most, and he was already very familiar with what Wang Ke's car could see, in Li Ke's opinion, Wang Ke's car was not at all what Datang's technology could achieve, there were a lot of objects in it, and the materials used, he couldn't know what was made of, and now when he heard Wang Ke say this, he also knew that Wang Ke didn't tell a lie, so he stood up and said briefly to Comrade Li Er, to prove that Wang Ke is indeed not lying.

Comrade Li Er has always been very interested in Wang Ke's car, but because of face, and no one can drive, he has not had the idea of beating Wang Ke's car, but if he really wants to build a car, he still hopes that Wang Ke can make a few cars according to the appearance of his car, and at that time, he can also justifiably send someone to find Wang Ke to learn driving skills, but now not only Wang Ke said that he couldn't build it, but even his own son said so, which extinguished the little hope that had just risen in Comrade Li Er's heart. Comrade Li Er had no choice but to wave his hand helplessly and motioned for Wang Ke to continue talking about the four-wheeled carriage.

Wang Ke told in detail what he knew about the four-wheeled carriage, and when he told Li Ke just now that there was no way to build a car, Comrade Li Er's disappointed expression, Wang Ke saw it in his eyes, and now of course Wang Ke wants to give Comrade Li Er a relief.

Wang Ke said to Comrade Li Er: "Your Majesty, this four-wheeled carriage is much stronger than a two-wheeled carriage, not to mention the speed, and the driving is much more stable, even after stopping, it is also convenient to get on and off the carriage, if the emperor switches to a four-wheeled carriage, it is much stronger than the current two-wheeled carriage." ”

Wang Ke's words will definitely not be wrong, the four-wheeled carriage because of the two more wheels, the upper compartment board must be much longer than the two-wheeled car, if it is made into the current two-wheeled car like the carriage style, but it is much more spacious than the two-wheeled car, and there is no need to enter and exit from the front like a two-wheeled car, but can open the 'door' on both sides, and it is much more convenient to go up and down.

When Wang Ke said this, he couldn't help but think of the carriages that often appeared in Western movies in later generations, and the four-wheeled carriages he imagined were completely born there.

Comrade Li Er has always been very accepting of these new things, but now when he heard Wang Ke say this, he couldn't think about it in his heart, so he turned his head and asked Li Ke, how long will it take for this four-wheeled carriage to be made.

Li Keleng paused for a moment, and then said with some hesitation: "Father, it seems that this thing is made of wood, and the sons are all made of metal, so this shouldn't be made by the sons." ”

Wang Ke saw that Comrade Li Er was thinking of Li Ke first about everything now, and knew in his heart that Li Ke already had a high status in Comrade Li Er's heart, and of course he was quite happy in his heart, so he hurriedly said: "Your Majesty, don't let His Highness do this thing, let the craftsmen in the village make it for the emperor." After it is made, the emperor will let the palace craftsmen imitate it. Your Highness also has a lot of things going on there, and now he has to find a new location to expand the scale, which is really busy. ”

Comrade Li Er saw that Wang Ke took the initiative to agree, of course, he had no opinion, and now that everything had been said, as soon as the 'spirit' spirit relaxed, he immediately felt a little hungry, and hurriedly waved his hand to let Wang Ke and them leave.

Wang Ke has been hungry for a long time, but he has been dragged and said for a long time, and now he is finally relieved, and he must be leaving immediately, and he is really afraid that Comrade Li Er will remember something after a while, so he will not give the hungry front 'chest' to the back.
