Great Tang princess

After putting down the phone, Li Xian raised his eyebrows, looked at the surprised Wei Lian'er and the concubines beside him, and said with a smile: "Well, it seems that's all..."

"Your Majesty, can this thing really talk to people from the Ministry of War?" Wei Lian'er asked curiously.

The other three concubines also had curious expressions on their faces, staring at him with burning eyes.

After all, this kind of thing is indeed quite miraculous. In the eyes of the ancients, the matter of real-time communication was inconceivable.

When the telegram was first made, it caused a frenzy of discussion, let alone the device that can directly talk now.

Li Xian had an inscrutable smile: "Well, it is true that I can speak, but the voice is very small. I have to talk to Yuechen about it and improve it..."

Although he was also shocked by this effect in his heart, as an emperor, he must not show it, especially in front of his own harem.

As the saying goes, pretense is also one of the driving forces of human progress.

On the other side of the Ministry of War, Li Chongrun was working out in the gym when he suddenly received a call from his father asking him to come to the palace.

Li Chongrun, who was naturally smart, immediately realized that it must be because his father had nothing to do to make phone calls.

But no matter what, I had to tell myself not to go, so I could only wash my face and set off.

Arriving at Jixian Temple, before entering, I heard Li Xian's voice on the phone.

It sounded like he was chatting with the cabinet. After seeing his son coming in, he hung up the phone.

"Grandpa called the child, what's your order?" Li Chongrun asked.

"No no……"

Li Xian waved his hand: "Just to see what this phone is for!"

Good guy, you directly admitted that you were the one who asked me to come here because you had nothing to do... Li Chongrun complained wildly in his heart.

"Grandpa, this phone is used for daily affairs, it's better not to play around if you have nothing to do." Li Chongrun said.

It has been an incredible thing since ancient times for a son to teach his father a lesson.

However, Li Xian didn't care at all: "Hey, being a father is just a matter of curiosity."

It sounds like he didn't listen at all, and now his attention is focused on the playability of this phone.

Li Chongrun was too lazy to say: "Since there is nothing wrong, the boy will go back first."

"Wait, sit down and drink some tea, and explain the function of this phone call to Weifu in detail..." Li Xian beckoned.

In desperation, Li Chongrun could only sit down and talk to him in detail.

He also knows many of the principles. Although it is not as good as those in the Engineering Academy, it is not a problem to give Li Xian a simple science popularization.

So I sat down and explained to him in detail, including that this phone will continue to be upgraded in the next few years.

At least it must be able to extend the call distance to more than ten kilometers before it can be called a real phone.

At the same time, in the future, Li Xian will have to reduce the number of phone calls in person. Most of the orders should be handed over to Sun Jingbang.

Otherwise, if the dignified emperor answers the phone in person, it will reduce the compulsion a lot.

After hearing this, Li Xian took it for granted, feeling that his son was right.But before that, let's play for a few days.

……

After the telephone was officially used, it did improve the efficiency of the imperial court a lot.

Especially for the cabinet that is mainly responsible for handling daily government affairs, if there is any problem, it can be contacted by phone immediately.

Some things that are not so confidential can also be discussed directly on the phone, saving a lot of time.

As a result, the efficiency of work has been improved a lot. Such an obvious improvement directly silenced all the officials who were still opposed to the phone call.

After all, it’s a fool not to use such a convenient thing. Now that it’s been installed, don’t think about objecting, just obediently use it together.

So the voice of opposition a few months ago disappeared suddenly, as if it had never existed.

This matter made Li Xian very interesting, and he wanted to discuss it with his sister.

But Li Yuechen didn't have that free time. At this time, he would go to the Engineering Academy every day after class to do the final test with the craftsmen.

After a long period of hard work, the first real car in the Tang Empire was gradually produced.

Although in terms of quality, it is definitely not as good as the cars made by mature automated industrial factories in the future, but basically it has everything that should be available.

As for the shape of this car, Li Yuechen chose an SUV model.

I originally wanted to make a truck, but the second engine is not big enough for the truck to carry it.

What's more, it is still in the experimental stage, and the cost of making a truck as soon as it comes up is too high.

However, cars are not good either. Although hardened roads are paved in the city, there are still dirt roads outside the city, and the chassis of cars is still too low.

So Li Yuechen chose an off-road model as the first test product.

If successful, all future military vehicles can be made according to this model.

After so long in the making, the car is finally nearing completion.

Although from the perspective of the future, it is still no different from a car that is about to be scrapped.

But now when doing experiments, I don’t pursue aesthetics or anything else, as long as I can move.

At present, the car is just a shell, with no doors, no glass windows, air leaks from all sides, and even only one seat...

But there are all the parts that should be there, including the tachometer and speedometer.

This kind of mechanical watch is actually quite simple to make. For example, the speedometer is to twist the spring connected to the pointer through the flexible shaft installed behind the wheel, and the current speed of the vehicle is displayed through the pointer.

It's just that there is a problem with this mechanical speedometer, that is, the metal flexible shaft will fatigue and break after a long time.

This is also the reason why many old-fashioned cars can still move, but the speedometer does not move.

But even so, it has to be done.

Because the driver must know how fast he is now, otherwise it is a very dangerous thing.

As for the problem that the metal shaft is easy to break, the big deal is to change it when the time comes.

On the last day of October, the day of this car test finally came.

Li Yuechen got into the car under the eyes of everyone, grabbed the handle under the steering wheel and pulled it back.

The engine started and made a low roar, and the rotation of the engine on the front of the car that hadn't been covered could be clearly seen.

Seeing the smooth start of the car, the craftsmen held their breaths and waited for the next test.

Sitting in the car, Li Yuechen stepped on the clutch pedal, put it in gear, and slowly released the clutch.

The next moment, the car slowly began to move forward, driving smoothly.

"Alas--"

At the moment when the car was running smoothly, all the craftsmen present cheered together.

Even two of them knelt on the ground and shouted excitedly, while others hugged the people next to them directly.

Another craftsman from an ethnic minority took off his coat and danced on the spot.

For such a long time, in order to make this stuff, they have really experienced unimaginable pressure.

For them, this is a black technology that has never been touched.

If it weren't for not wanting to live up to the princess's expectations, many people would probably be tempted to give up and give up.

Thinking about it now, the design drawings were so complicated that it was overwhelming, and the parts were so high-precision that they once doubted their own skills...

When they saw the real thing at this moment, they felt that the effort during this period was worthwhile.

They lived up to the princess' expectations, and really made this car like a magic weapon of a fairy!
At this time, Li Yuechen also came to the door, and waved to the soldiers standing guard at the door: "Open the door, I will go out and try!"

The two surprised soldiers quickly opened the gate, and then watched the car go all the way out of the gate.

After walking out of the gate, there is a wide road. After turning the corner, Li Yuechen directly entered the second gear, began to speed up slowly, and went straight to Xuanwu Gate.

Then third gear, fourth gear...

This road connects the Xuanwu Gate of the Imperial Palace and the Qianniuwei Camp. No outsiders will come here on weekdays, so you can speed up the test as much as you want.

The only thing to pay attention to is that a hare might suddenly pop out somewhere.

Although this engine is completely made according to the appearance of the future, the level of craftsmanship is still quite different after all.

So in the end, Li Yuechen's measured maximum speed was about [-] or so.

The determination of this value also has a certain basis.

As an extreme athlete, Li Yuechen really tested himself on a motorcycle.

At speeds below [-] per hour, there will be no response to adrenaline at all.

Only when it exceeds [-], can you feel your heart rate rise and adrenaline start to secrete.

Of course, I don't know if it will have an impact if I change my body now, but at least my spirit should not change.

But let's just decide, after all, the current body of this car can obviously feel the vibration when it exceeds [-], and it is estimated that this is the limit speed of this car at present.

All the way to the square outside the Xuanwu Gate, the soldiers who were standing guard looked at this mechanical beast rushing out of nowhere, and froze in place.

But after seeing the people sitting in the car, he relaxed again.

Since it was created by the eldest princess, there is no need to worry.

And Li Yuechen didn't stay here too long. After strolling around the square for a few laps, he turned around and returned to the Engineering Academy.

……

However, this matter soon reached the emperor's ears. When he heard that she had come out in a new car, Li Xian called her to the palace the next day to inquire about the specific matters.

"Yuechen, that new car, how about letting brother take a ride?"

"Brother, don't worry. The car isn't fully finished yet, and brother doesn't know how to control it. After I'm done, I'll take you to play."

Li Xian shook his head: "In terms of manipulation, don't you just learn from me?"

"You are an emperor, how can you drive yourself? It's useless to learn, and I'll just take you for a ride." Li Yuechen waved his hand.

It's not that I can't trust my brother, the main reason is that he is too playful, if one day he drives out to play on a whim, it will be really troublesome.

If there is another accident, it will be the biggest scandal since the founding of the Tang Dynasty, and I really can't trust him in this regard.

……

In this way, the development of the car was considered a success, so Li Yuechen immediately began to negotiate with the Engineering Academy for subsequent project approval.

The first is the aircraft, which is the most important thing, and we must invest our best efforts to get it done as soon as possible.

At the same time, supporting equipment such as altimeters and pressurizers are already under intense research and development and experiments.

Li Yuechen first drew a Wright plane for them to try to make. As long as the first model can take off successfully, they can try the Bellanca plane.

Then there is the car project. In this era, cars are not considered, and only two models will be made in the future.

The first is off-road vehicles, and the second is trucks.

Needless to say, trucks are indispensable whether they are transporting goods or carrying people, and they can even play a huge role in future economic development.

As for off-road vehicles, some small tasks in the army can usually be handled by off-road vehicles, which can also be regarded as vehicles for carrying out tasks.

Only these two cars should be settled first, and then consider issues such as cars.

And the biggest problem at present is that the cost of the vehicle is too high, and the cost cannot be reduced in a short period of time, and there is no way to sell it as a commercial vehicle. This is the most troublesome.

Fortunately, this situation will not persist for too long. We can make a few more trucks, and then set up a freight company to transport goods for those big merchants.

In this era, the Escort has not yet developed, it just has a prototype.

Therefore, Li Yuechen planned to let the royal family do this business, and it could also generate some income, so that there would be enough funds for subsequent research and development.

The shipping agencies established by the royal family are at least more secure than those independently established by the people.

At least in Li Yuechen's opinion, the kind of bodyguard agency written in many novels is more like a mercenary organization than a courier industry.

Running darts is often only part of the business, and many escort agencies will also take on kidnapping, assassination and other jobs.

Moreover, in many novels or film and television dramas, there are escort bureaus who see that businessmen are rich, and in turn blackmail them.

Although it is said that this is a plot in a fictional work, no one can say whether this kind of thing has actually happened in real history.

Therefore, it is better for the country to replace this kind of organization that is unstable to the society as soon as possible.

In this way, businessmen don't have to worry about being blackmailed, and the royal family can also have a stable income, which is a win-win situation.

After confirming his thoughts, Li Yuechen immediately went back to discuss with his sister-in-law Pei Qingwan and asked her to help write a plan.

There is no need to worry about this matter, just slowly improve the regulations first.

As for the name, well, why not call it Datang Post?Li Yuechen thought to himself.

At this time, Pei Qingwan raised her own question: "According to what His Highness said, this truck driving skill needs training, so is there still a need for a special training place?"

"Well, we really need a driving school..." Li Yuechen nodded slightly.

When it comes to driving school, Li Yuechen feels a bit difficult.

Should we use the test-taking mode as the driving school in the future, or try to make it as difficult as possible to obtain a driver's license like some countries? (end of this chapter)
