"How can my grandson have time to see me today?"

The car had already driven outside the temple.

learned from the mouth of the chamberlain that this time the prince came with the imperial grandson and the imperial granddaughter, and Li Kuo, who was resting in the harem, also had to reluctantly cheer up and then "welcome the guests".

"The son has seen his father."

"My grandson has seen Your Majesty."

"Back to my father, the car has been studied."

"Cars?"

Li Chun said, "It's the tricycle from before."

Li Kuo said, "Isn't this a long time ago?"

Li Chun said, "Father, this time is different. This time, what we have developed is a more reliable car."

Li Kuo: "What is the specific manifestation?"

Li Chun said, "First, the travel rate can reach every hour, and you can walk up to 1,800 miles."

If you do the math, it's almost a hundred kilometers.

You know, usually the ancients traveled, maybe they walked twenty or thirty miles a day.

Of course!

If you don't have bad money, don't eat or drink, and are on the road all the time, you can naturally reach the speed mentioned above at the end of this day.

You must know that Datang is still quite prosperous in the horse rental industry.

But the question is......

This horseback riding is not a lot of enjoyment.

This one is upside down.

Merely......

The current Li Chun obviously hasn't taken these into account.

Li Chun continued, "You must know that even though the fastest horse can achieve this kind of travel rate, after running for an hour, or even half an hour, it may take half a day, or even several days, for the horse to fully recover."

"So the best thing about this car is that it doesn't get tired like a horse, and you can even drive it for hours in a row."

"This is one of the things where it is more reliable than a horse."

Li Kuo also said, "What about the second?"

Li Chun: "Second, because the previous car only had three wheels, once the speed was too fast, it might roll over when turning."

"And now...... We've improved this so that even if we go through corners at a faster speed, we won't roll over."

Li Kuo: "Oh? How is this solved?"

Although Li Kuo usually doesn't attach much importance to the upgrading of technology, he still knows that it is of great significance.

Li Chun said, "This ...... The credit may also go to your father and your good grandson."

Li Kuo turned his head suspiciously, lowered his head and looked at Li Chong.

Li Chun continued, "It was Chong'er who solved this problem."

Li Zhong hurriedly said, "It's just a matter of luck, and it just happened to be solved."

Li Kuo: "How did you solve it?"

Li Chong: "Use the differential."

Li Chun: "It's probably not very clear just by saying it, Father, it's better to go and have a look."

Li Kuo: "Lead the way."

Subsequently......

So the group went out of the temple to see the car.

Unlike the three wheels that Li Kuo saw in the past, this one is four wheels.

And in terms of appearance, it has also changed a lot from the previous one.

Plainly!

As soon as you look at it, it feels very stable.

Although the triangle has stability, which is the consensus, when it comes to turning, this principle does not work at all.

"I'll show your majesty."

Let's talk about it......

Li Chong was going to go up to drag racing.

As a result, he was pulled by his sister.

"Let the craftsmen of the Academy of Sciences show it to Your Majesty."

The craftsman saluted, and then went up.

All I can say is......

The place outside this temple is okay.

It's quite big, it's used for testing, and it's not a big problem.

First it was a straight line, then a slow U-turn, then a straight line, and then a little bit faster in the corner.

Presented to the end......

It is also a serpentine position.

It turns out!

The car is not only stable, but also extremely nimble.

Seeing it, Li Kuo couldn't help but want to go up and try it.

After all......

Unless it's a woman, if it's a man, how can he walk when he sees such a thing.

At last......

Unable to help his curiosity, he sat down despite everyone's dissuasion.

He also made a variety of flexible moves.

All I can say is......

There's nothing wrong with driving this.

It's very smooth and there is no bump in horseback riding, not to mention, and at the same time, it has a sense of control.

Why are people who sit in cars far less cool than people who drive?

It's because I lack that feeling of being in control.

Of course!

Sometimes this car is driven too much, and you have to pay attention to the traffic rules, and you have to look at the road or something, sometimes, indeed, it will also make people feel that driving is not good.

Can ...... now

Li Kuo hasn't gotten there yet.

Finally, the car stopped not far from the trio.

Li Kuo may have really had a good time, and after getting out of the car, he laughed, "This car is doing well, it is much better than the previous feeling."

Li Chong also said, "Grandson thinks that this is not what it will be in the end."

Li Kuo: "Oh?"

Li Chong said: "My grandson thinks that it can be made waterproof and sunproof, and then, you can drag another car pocket in the back, so that you can load and unload goods."

"Imagine if it looked like a wagon pulling goods."

"Steam locomotives are generally used for long-distance cargo pulling, and if this car is made larger and the engine is better, it can completely fill the shortcomings of nearby places, such as the suburbs of Luoyang, and Datang lacks short-distance transportation means."

"Possibly...... In the past, transportation had to be carried by horse-drawn carriage."

"Now...... As long as this is made bigger, not only can it be used to pull people, but it can even be used to pull goods, and one should be able to hold at least a dozen carriages and carriages in the past."

"What's even better is that Datang doesn't have to raise horses in the future."

"Naturally! It will definitely be harmful."

"Then once this thing is fully used, then there may not be so many people, so many horses, and those people and horses will lose their livelihood."

"Your Majesty, I have found a problem."

Li Kuo stared at Li Chong, staring deadly.

"I have found that science is actually a double-edged sword, with both good and bad points," Li said.

"Of course, if you can take advantage of it."

"For example, this cart can top more than a dozen horse-drawn carts in the past, so if it is used to pull grain, vegetables or something, then the price of grain and vegetables, at least in terms of freight, can it be reduced a lot."

"Then the people will be able to buy food and vegetables cheaper than before."

"If we can make good use of science, it will definitely make the people's lives better and better in the future, but if someone uses this to make money for themselves and desperately oppress the people, the original dozen carriage drivers are now all losing their livelihoods, then it may cause turmoil in the future."
