Yizhou New Town, the change is so fast.

Walking on the street, Li Su only felt that in a few years, Yizhou would be able to surpass Chang'an City and become the largest city in the Tang Dynasty.

But after walking a few steps, Li Su found that someone was digging a pit in the street.

Well?

What's going on?

This street is all cement roads, dig a pit on a good cement road, and destroy all the surfaces.

And it's not just a pit, but the whole road, where people are digging holes.

The patrol police on the street, no one even cared about this matter.

Seeing this scene, Li Su's face couldn't help but darken.

What the hell is going on?

What happened when he was not in Yizhou City?

Li Su asked Li Yuanfang to inquire about the situation.

Soon, Li Yuanfang brought back the news.

It turned out that Di Renjie sent people to do all this.

It's actually Di Renjie?

Li Su took Li Yuanfang and went directly to the scientific research institute to find Di Renjie.

Soon came to the scientific research institute and found Di Renjie.

"Renjie, why did you send people to dig holes in the street, what are you doing?"

Di Renjie smiled and said, "Master, of course you are digging a pit and burying the telephone pole!" ”

Li Su couldn't help frowning and asked, "Okay, why are you burying the telephone pole?" ”

Di Renjie continued to smile and said: "Master, we have already researched the hydroelectric generator, and when the poles are buried and the wires are erected, the electricity can be turned on." ”

What the?

It's only been a year, and they've developed a hydroelectric generator?

Li Su couldn't help but ask in disbelief: "Just a few of you, you can develop a hydroelectric generator in a year?" ”

Hearing the master's words, Di Renjie couldn't help but show pride on his face.

Then he smiled and said: "Master, it's not just a few of us, our current scientific research team has reached thousands of people." ”

"In addition, Shangguan Changshi has given strong support to our scientific research institutes. At present, the scientific research institute has a special subordinate manufacturing plant and subordinate workers, which has reached tens of thousands. ”

"These people are all talents that Shangguan Changshi has excavated from all over the country. Now, our scientific research capabilities are getting stronger and stronger! ”

There are thousands of scientific research teams?

Li Su couldn't help but continue to wonder and asked, "However, it is impossible for there to be thousands of normal graduates?" Where did these people come from? ”

Di Renjie smiled and said, "Master, that's the case, the vast majority of people here haven't graduated yet. It was I who decided to let them participate in scientific research before they graduated, and the practice would be more profound than what they would learn from books. ”

Li Su greatly agrees with this viewpoint.

Future generations of college students will also have a one-year internship period.

If there is a scientific research scale of 1,000 people, and there are ready-made drawings provided by Li Su, it is indeed possible to develop a hydroelectric generator within a year.

And Li Su saw that Di Renjie in front of him was pale, his eye sockets were deep, his hair was unkempt, and he didn't know how much time he hadn't washed it.

Through these, it can be seen that they have paid too much in this year.

Li Su asked again: "By the way, have you also made a transformer?" ”

Di Renjie nodded again and again and said, "The master is relieved, the transformer has also been made, and now the master is back just right." It can help us detect where there are still defects and deficiencies, and we can improve them. ”

This kind of thing, even if Di Renjie doesn't say it, Li Su will check it.

Electricity is not just a joke, and if it is not done properly, it may cause a major disaster.

At that moment, under the leadership of Di Renjie, Li Su came to the water storage place first.

Yizhou's river resources are quite abundant.

Hydroelectric power is set up just outside the city of Yizhou.

Where, there is a waterfall that is not big or small.

The impact of the river from above left them with the work of damming.

Otherwise, I am afraid that the work of building the dam will not be completed in one year.

Hydroelectric generators, already installed.

This hydroelectric generator looks rather bulky.

Uh, okay.

In fact, the drawings of the hydroelectric generators provided to them by Li Su are relatively primitive.

After all, the new type of hydroelectric generators, albeit with much higher utilization.

However, the scientific and technological content in it is also much higher, and with their current scientific and technological capabilities, it is impossible to overcome it in a short period of time.

The most primitive hydroelectric generators are relatively easy to make.

Li used the system to test the hydroelectric generator, and the results detected three problems.

When Li Su raised these three questions, Di Renjie was still a little unconvinced.

Because now their level of scientific research is quite good.

They have experience in manufacturing steam tricycles, and now their research and development capabilities are actually not weak.

The research on the hydropower generator was completed in half a year.

The remaining half a year is all for assembly, and then continuous testing.

For half a year, they don't know how many times they have been tested, looking for all kinds of problems, and then solving them.

In the past month, after various tests, they have not been able to find any faults and defects.

They think they're doing it all right now.

But the master has just arrived, and after a casual observation, he can see three problematic places?

How is this possible?

Di Renjie didn't believe in this at all, not even a master.

I love my teacher, but I love the truth even more.

This is also Di Renjie's most convincing sentence.

Immediately, Di Renjie found someone to test the three problematic places raised by the master.

Di Renjie hopes to prove that the master is actually wrong.

However, the results of the test shocked Di Renjie to the point of no return.

Because, there were two of the three problems mentioned by the master, and they detected the problems on the spot.

In the past, the reason why they didn't detect it was because these two problems were very hidden.

Now they are also aware that there may be problems in these two places, and they are specifically testing these two places to detect the problem.

On the other hand, there is no problem with their testing.

And Di Renjie felt that since the master pointed out that there was a problem here, he would not be untargeted.

Next, Di Renjie personally tested and still found no problems.

Di Renjie continued to test, tested three times in a row, and finally found the problem.

At this time, Di Renjie's cognition of the master was refreshed again.

Master, it's really amazing!

The problem that the master saw at a glance, he actually needed to check it three times in a row before he could check it.

And these three problems are actually very serious problems.

If it is not solved as soon as possible, the hydroelectric generator will be scrapped in a short time.

It can even cause major disasters.

After inspecting the hydroelectric generator, Li Su inspected the substation room and other equipment next to each other.

And then keep asking questions along the way.

And Li Su pointed out that there are problems, and after they have repeatedly tested them, they will definitely be able to detect the problems.

They tested for several months, but they couldn't detect the problem, and the king of Shu could only see it at a glance.

This can't help but make all the scientific researchers admire the King of Shu to the point of no return.

After two days of testing, Li Su pointed out all the problems.

Solving these problems, as long as the daily maintenance is done well, Li Su believes that there will be no major problems in at least ten years.

At the same time, in the entire Yizhou New Town, the telephone poles have basically been planted.

Because the hydropower resources of rivers are not particularly abundant, the power generation capacity is not very large.

It is enough to maintain Yizhou New Town, even if Yizhou New Town expands by two or three times, it will be enough.

But it is unlikely that it will radiate to the surrounding area.

And on the side of Yizhou New Town, Li Su just wants to use it as a test site.

In fact, there are still deficiencies in hydroelectric generators.

If you want to promote electricity to the entire Datang, Li Su feels that it may take more than ten years or even decades of effort.

Let's not talk about the problem of technology and manufacturing capacity, let's just say that professional engineers, electricians, and maintenance personnel, without ten years of hard work, you can't train them.

Unless the emperor can increase the scale of education, science education will be promoted throughout the Tang Dynasty.

However, I am afraid that this point is not easy to implement.

Now in Yizhou New Town, schools and research institutes, as well as government offices, electricity is free.

There are also telephone poles on various roads.

Of course, now Yizhou New Town is more of a shop.

It can be said that shops occupy at least eighty percent of the buildings in Yizhou New Town.

If these shops want to use electricity, they have to spend money.

And the cost of each kilowatt-hour of electricity is quite expensive.

One kilowatt-hour of electricity requires an electricity bill of fifty yuan.

That's the equivalent of a hundred dollars for the Hereafter.

One hundred yuan per kilowatt-hour of electricity is definitely a high-priced electricity.

But there is no way, the investment in hydroelectric power plants is very large, and it also requires a lot of money to maintain them.

If you want to pay for yourself, you have to work out such a price.

And because the price is too expensive.

And those merchants are also very shrewd.

After this electricity is introduced into the home, it only plays the role of lighting.

I heard that it is very bright, and it can be as bright as day.

Of course, it depends on the power of the bulb.

But the higher the degree, the more power is consumed.

They have a lot of stores, and they don't do business at night.

What's the use of whether it's lit up at night?

If they really want to illuminate, they don't have candles.

Fifty dollars, how many candles can you buy?

The candles bought for fifty dollars can fill the whole room, don't you believe that they are not as bright as light bulbs?

Based on this consideration, therefore, more than ninety percent of the shops in the entire Yizhou New Town do not have electricity.

Because they feel that it is useless at all.

Once the pole is erected, the next step is to thread the string.

Because everyone is doing it for the first time, they have no experience at all.

Therefore, in the beginning, the stringing speed is very slow.

Several times, there were almost accidents.

It was only under Li Su's guidance that they mastered the skills of stringing.

And the speed is getting faster and faster.

After about a month of busyness, finally, all the work has been prepared.

Now all that's left is the final commissioning.

As long as the commissioning is passed, Yizhou New City can complete the electrification work.

Yizhou will open a new chapter in human progress.

……

Before you know it, it's the end of the year again.

The time has entered the wax moon, and it seems that it is time for the New Year again.

On this morning, after waiting for the ministers to report the matter, Li Shimin couldn't help asking: "Everyone, Aiqing, I don't know if there is anything to report?" ”

At this time, Cheng Yanjin stood up holding his stomach.

"Your Majesty, Your Majesty, I Lao Cheng is sick and wants to take a sick leave."

Seeing Cheng Biting Jin's appearance, Li Shimin couldn't help frowning.

This old thing is obviously about to celebrate the New Year and wants to be lazy.

Look at you, your face is very ruddy, much better than my complexion, does this look like you are sick?

It's not like a fake!

However, the left and right are fine now.

Anxi Protectorate, since Qin Qiong arrived with 50,000 soldiers and horses, he recruited 50,000 soldiers and horses in Persia.

100,000 soldiers and horses were stationed, hiding in all directions, and no one dared to move.

Of course, in this, there is actually a lot of credit to the King of Shu.

If it weren't for the fact that the King of Shu had been afraid of the Great Eclipse before, I am afraid that there would not be such peace now.

As for Tubo and Tuyuhun, before the King of Shu led his troops to attack Dashi, he might still have a little idea.

But after the King of Shu came back, there was really no idea at all.

Even the Turks, at this time, are living with their tails between their legs, an honest batch.

As for the Goguryeo side, there is no conflict for the time being.

Now that Datang is leveling down, Cheng Biting Jin, an old man, wants to take a vacation, and Li Shimin is too lazy to ask.

"Well, I don't know how long Aiqing needs to recuperate, right?"

Cheng Biting Jin counted with his fingers and said, "What's the matter, it will take three months, right?" ”

Suddenly!

If you pretend to be sick and take three months of sick leave, don't you have any points in your heart?

Li Shimin couldn't help but ask with a dark face: "Or, I will give you twenty years of sick leave, right?" ”

Hearing Li Shimin's words, Cheng Biting Jin was overjoyed at first.

Twenty years, is the emperor so generous?

But I immediately thought that something was wrong, I Lao Cheng, it seems that I may not be able to live for another twenty years, right?

Taking a vacation for 20 years, isn't this equivalent to directly taking off my official position as Lao Cheng?

Thinking of this, Cheng Yanjin hurriedly said: "No, no, hehe, it won't take so long, Your Majesty, you can give me Lao Cheng a month!" ”

A month is just right to take a break until after the Chinese New Year.

I didn't have to be on duty all year ago, and it was absolutely beautiful.

Li Shimin didn't have time to talk to him more, so he couldn't help but say: "Okay, I'm ready, after Aiqing goes back, take care of your illness!" ”

Cheng Biting Jin said with a smile: "I old Cheng, thank you to the emperor." ”

After Cheng bit the gold, Wei Chigong also stood up and said, "Your Majesty, I'm sick too!" ”

Li Daozong followed and stood up: "Your Majesty, I'm sick too......"

Suddenly!

Are you all sick and crowded?

To get sick, to get sick together?

No need to ask, these guys must have seen that the New Year was approaching, and they made an appointment to go to Yizhou to play together.

They go to Yizhou at least two or three times a year.

Thinking of this, Li Shimin couldn't help but feel a sense of dissatisfaction in his heart.

Hum!

I'm so busy every day that I don't have that much time to go to Yizhou.

And you, if you want to go, you can go?

Thinking of this, Li Shimin couldn't help but deliberately ask with concern:

"Oh, all of you Aiqing are sick? I'm afraid I don't have a bad disease, right? ”

"In this case, I will send the imperial doctor of the Tai Hospital to follow you for treatment, and for this month, I will live in your house and give you good treatment to ensure that your illness is cured."

Hearing Li Shimin's words, Cheng Yanjin, Wei Chigong and a bunch of old people were dumbfounded.

They're not sick at all, and when the doctor comes, won't they be exposed?

Besides, the purpose of their sick leave was to make an appointment to go to Yizhou together.

Yizhou is so fun, it's definitely a good place to take a vacation.

If the Imperial Doctor lives in their house for a month, even if they can't see through them pretending to be sick, they won't be able to go to Yizhou.

If they can't go to Yizhou, why should they take a month's leave?

Do you have to lie in bed and pretend to be sick every day?

If that's the case, then they'd rather not take time off work and go to work every day.

And Wei Chigong and Li Daozong hurriedly looked at Cheng Yanjin.

The actions of these old goods choked Cheng Jinqi enough.

What do you see Lao Cheng doing?

I'm not the only one asking for leave.

Besides, if I Lao Cheng is the only one who asks for leave, and you don't all ask together, will there be such a thing?

Cheng Yanjin hurriedly said: "Your Majesty, my old Cheng and them are all minor problems, where do you use the imperial doctor?" No, no, really not, hehe! ”

Wei Chigong also hurriedly said: "Your Majesty, you really don't need it, it's just a little problem!" ”

Several other old goods also followed suit.

And Li Shimin, still with a black face, said: "My courtiers, so many people are sick, if I don't care at all, what will the people say about me?" Don't talk about this anymore, it's decided! Okay, scatter the dynasty! ”

With that, Li Shimin strode out.

Cheng Biting Jin and a bunch of old goods, such as mourning.

The other ministers had schadenfreude on their faces.

Of course, they didn't dare to be so happy in front of Cheng Yanjin and the others.

If these old people see it, they may be beaten, and there is no place to reason.

Wei Chigong and the others said with a sad face: "What should I do now?" If the emperor really sends the imperial doctor to our mansion, will we really have to lie in the mansion for a month? ”

Cheng gritted his teeth, and then said, "Let's go, let's go to the emperor!" ”

……

A few days later, the emperor had another attack of qi and decided to go to Yizhou to recuperate.

This time, the crown prince was left behind to supervise the kingdom again.

However, this time, the emperor basically did not give the prince any rights.

All things are decided by Fang Xuanling and several important ministers such as the eldest grandson Wuji.

The role of the prince is basically zero.

It can be seen that the prince has really fallen out of favor.

And this time, the emperor accompanied him to Yizhou to recuperate, including Cheng Yanjin, Wei Chigong and Li Daozong and other generals.

It turned out that the last time the emperor wanted to send the imperial doctor to their house to treat them.

Cheng Yanjin and a bunch of other old people panicked, and then, at the instigation of Cheng Yanjin, they found the emperor.

Then, these old goods instigated together, and the emperor who finally instigated them was also moved and decided to go shopping in Yizhou with them.

Several major events have occurred this year, such as the death of Empress Changsun, the invasion of the Tang Dynasty by Dashi, and the assassination of the crown prince Li Chengqian, which is like stabbing Li Shimin twice in his heart.

Li Shimin feels that his current energy is not as good as before.

It's good to go to Yizhou to relax.

So, Junchen and his entourage, with 2,000 guards, stepped on the train to the south.

This time, Li Shimin carried out another surprise attack, and did not inform Li Su, the king of Shu, in advance.

Of course, in fact, Li Su has his own news channels.

Li Shimin is coming to Yizhou today, so he naturally knows about it.

However, since Li Shimin didn't tell him, he naturally pretended not to know about it.

Li Shimin and the others, after coming to Yizhou, did not let anyone go to Li Su.

Instead, he came directly to Yizhou New Town.

Not long after, Li Su learned the news that the emperor had come to Yizhou, and hurriedly rushed over to say goodbye.

"The son doesn't know that his father is coming, and he is late to greet him, and I hope that my father will forgive his sins!"

Li Shimin smiled slightly and said: "Those who don't know are not guilty, I deliberately didn't tell you, and I can't blame you." ”

"By the way, just now on the street, I saw a high pole on the street, and the pole was still wearing a thread, I don't know what it was for?"

What Li Shimin said was naturally telephone poles and wires.

When they first came to Yizhou, Li Shimin, Cheng Yanjin and others were also shocked.

This year, because of the death of Empress Changsun, the attack on Datang and other things, they have been in Yizhou for nearly a year, and they have not come to Yizhou.

And after coming to Yizhou again this time, I found that Yizhou has changed so fast.

They were almost unrecognizable.

In less than a year, Yizhou New Town has almost doubled.

The number of tourists on the street has also become more numerous.

I don't know how many more shops have become, and they have become more prosperous and prosperous.

That's all, but the poles and wires on the streets really make them puzzled and can't guess what this is for.

Therefore, as soon as he saw Li Su, Li Shimin couldn't wait to ask this question.

Li Su smiled and explained: "Father, what about that pole, it's called a telephone pole. The wire on top is called a wire. ”

"The purpose of the poles and wires is to transport the electricity generated from the power station to people's homes."

"When you have electricity, you can use electric light bulbs for lighting. This light bulb, which only needs one in each room, can illuminate the whole room as if it were daytime. ”

"And now, everything has been checked, and the electricity will be available tonight. My father is really lucky, and he is just able to witness the sacred moment when my Datang is powered on for the first time. ”

Li Su's words made Li Shimin a little confused, as if he understood or not.

And Cheng Yanjin and a bunch of old people just didn't understand.

Li Shimin couldn't help but wonder: "What is this electricity?" What exactly is the use? How did it come out? ”

This, it's really hard to explain.

Li Su organized a few words before he said: "Father, have you ever seen a thunderbolt in summer? This electricity and the thunder and lightning are actually of the same nature. ”

"Of course, the electricity we generate is much weaker than the lightning. These thunderbolts are a kind of energy, through which many things can be done. ”

"With this electricity, it can even be used as a power for trains, of course, these can't be done for the time being!"

"After my father has eaten dinner, please ask my father to take a look at the brightness of this light bulb!"
