If you want the Tang Dynasty to last forever for a hundred years, Li Ji must clear the surrounding threats, because you can't guarantee that firearms will not flow into other countries after a hundred years.

In case the old Li family comes out with a waste king, although this possibility is very small, Li Ji does not dare to take this risk, so he must take the Bohai Kingdom.

In fact, there is a more important reason, to take the Bohai Kingdom, Goryeo is in the bag. At least Goryeo will become a vassal country, and there will be little Japan, which admires the Tang Dynasty and worships the Tang Dynasty as a superior country. Japan and Goryeo have frequent exchanges, and if Goryeo is clamped, Japan will not be able to set off storms.

The Japanese nation, when they see that you are stronger than him, they will look up to you with great grovel. The people of their country are very resistant to wear, and they will do whatever it takes to learn from the advanced experience of other countries. Even if they step themselves into the mud, they don't forget to learn.

And once they learn your advanced experience, they will inevitably bully you, and the white-eyed wolf little Japan has been like this since ancient times.

Before the Manchu Qing Dynasty, Japan had always looked up to our Celestial Empire. And when it came to the era of braided slaves, they became restless.

The First Sino-Japanese Naval Battle was defeated by the Manchu Qing Dynasty, and the Republic of China was even more reckless in the land of China, and he even wanted to wait for the Tang Dynasty to complete the first quarter of the industrialization era, and drive a warship to wipe out this small country.

But when you think about it, the Japanese people in this period were still very honest, and it was not their sin to create evil in later generations.

There is nothing worth focusing on in the Bohai Kingdom, in a word, it is devastating.

After all, Yelu Abaoji, who was defeated by the army, was already at the end of the crossbow, and when he encountered the muskets and cannons of the forbidden army in the regular war, all the Khitan cavalry without suspense was beaten by the forbidden army.

Half a year later, the Bohai State was subordinated to the Tang Dynasty. Datang turned it into three prefectures and counties, Changbai Prefecture, Liaozhou, and Jizhou.

A rough iron factory smoked thick white smoke, and the molten iron continued to turn into railroad tracks. Datang has its own official department, the Department of Railways.

Railways are the blood of the country, and only when the blood flows non-stop can the country prosper.

With the first train, there is the hundredth. The train has greatly facilitated the economic and trade exchanges between various regions, and the treasury is about to burst.

Reduction, reduction and reduction. Today's people in Datang no longer worry about eating and drinking, and they are rushing to enjoy better. For thousands of years, only the Tang Dynasty Li Ji finally solved the problem of food and clothing for the people.

During the slack period, the people repaired water conservancy to protect the fertile land for irrigation.

With the information that Li Ji got back from modern times, all kinds of talents continuously cultivated by the imperial court began to give full play to their advantages in various positions in the Tang Dynasty.

Liuli factory, the first batch of vacuum bulbs were successfully made. Tungsten wire is based on the metallurgical refinement recorded in the data, and Datang has the ability to produce aluminum, tungsten, zinc, titanium and other metals.

Datang has set up a geological institute to survey energy reserves in various regions. Gold, silver, copper, iron, petroleum, coal.

Li Ji has recently been working on the construction of oil plants, with which the internal combustion engine can be invented and the steam train will be obsolete. Petroleum derivatives, rubber, plastics and other chemicals can also change the life of Datang.

There is also the Tai Hospital, and Sai Huatuo is the president of the Tai Hospital. They were exposed to Western medical theories for the first time, and now they know what antibiotics are and what surgery is.

What excites Sehuatuo is that he discovers the immense benefits of the combination of Chinese and Western medicine. Western medicine treats the surface, Chinese medicine treats the root cause, and the combination of Chinese and Western medicine is a perfect combination.

The industrial age is also quietly changing people's outlook on life. Feudal ignorance began to dissolve, and people became more and more receptive to new things.

In the glorious times, Chang'an Paradise had plans to move the capital to Chang'an, but later found that it would not work at all.

First of all, the center of gravity of the whole country has been placed in Luoyang, Chang'an is now in ruins, and with the development of the economy, Chang'an is becoming more and more unsuitable as the national capital.

If it is inferior, Youzhou is the most suitable. Youzhou is now Beijing, and the relocation of the capital is a major event, although the current capacity of Datang is more than enough. But in order not to waste money and money, Li Ji dispelled this idea and talked about it later.

Hanyuan Palace, everything is complicated ☆ I don't care about the process, as long as the result.

"Zhang Wenwei, how is our fertilizer plant being built?" In the main hall, Li Ji asked.

Zhang Wenwei, Li Ji's father-in-law. It stands to reason that Li Ji should be called a national abbot, but he doesn't, so he will call you Zhang Wenwei.

It's not that Li Ji doesn't know the number of etiquette, and Li Ji calls him by his name on official business. In private, it is the intimacy of the father-in-law and the father-in-law.

Fortunately, everyone is also accustomed to it, and the imperial historians rarely disagree with Li Ji now. This emperor is unrestrained, and everyone is used to it.

Zhang Wenwei stood up and said, "Your Majesty, the matter of the fertilizer plant is quite tricky. Although there are data drawings, there are too many raw materials involved, and it is difficult to overcome them for a while. ”

"I don't care, let Han E go up and let him be the commander of the fertilizer factory."

Han E, a guy who has a lot of research on agriculture, a guy who can't pull it out when he arches into the land, and a hero who promotes crops in the Tang Dynasty. Let him go to the fertilizer factory, which can be regarded as a suitable talent.

Zhang Wenwei arched his hand: "The minister obeys the order."

Fertilizers are indeed quite tricky, and they are not simply said to be made. But the more difficult it is, the more we have to build, because it is related to people's livelihood.

Chemical fertilizers can double or even several times the yield of crops, as well as herbicides and pesticides, although they are all blind eyes for the people of the Tang Dynasty, but these are the top priorities.

I don't know how Li Ji is going to tinker with information, and he will do everything he can to cheat, deceive, and steal. Come back and study according to the data, and experiment by yourself if you don't understand.

Xichuan saltpeter is mined in large quantities, gunpowder workshops are refining day and night, and the ordnance supervisor is constantly researching new weapons.

Zhu Youneng, the son of a loser, is better than Li Ji and gave birth to two sons.

As a father, Zhu Youneng has restrained a lot, and the word steady is written on his face.

"Brother Zhu, how about it, invest money!" Li Ji came to the Guangwang Mansion.

has been a friend for many years, Zhu Youneng looked disgusted: "It's definitely not good for you to come to me, you must be here to ask for money." Anyway, how much to vote? ”

Li Ji turned around and left: "Okay, I'll find someone else to invest."

Zhu Youneng immediately panicked, and immediately grabbed it to accompany the smiling face: "Hehe, Brother Li, just kidding." Invest as much as you want, you say yes, anyway, my money is yours. ”

Li Ji patted him: "When did I come to you to invest, and we lost?" Aren't they all making a lot of money, this time they are generous, investing five million taels. ”

Zhu Youneng is now wealthy: "Cut, I thought it was much, only five million taels, when will it be used?"

He didn't ask what he was doing with it, anyway, Li Ji would definitely be able to make a lot of money in the future. In fact, it doesn't matter to Zhu Youneng whether he has money or not, no matter how much money he has, it's just a beating number on his property.

"This is an investment, and there will be a lot of money to be spent in the future. The preliminary budget is at least 10,000 taels. Li Ji said lightly.

Zhu Youneng was taken aback, although it was said that the treasury of the Tang Dynasty was full now. The financial revenue is also rising, and the Kaiyuan cabinet is open all over the country, with semicolons everywhere.

But 10,000,000 taels, that is, 100 million taels. Although the two have a lot of assets in their names, they will definitely not be able to take out so much. Last year, the fiscal revenue only broke 10,000,000 taels.

"Brother Li, what are you doing here, need, need so much silver?"

"Have you been to my Imperial Palace?" Li Ji asked.

Zhu Youneng nodded: "I've been there."

"Are the two night pearls in the palace bright?"

Zhu Youneng said disdainfully: "That's a solar electric lamp, don't think I don't know." Wait, you're saying you want money to invest in a power plant? ”

Li Ji smiled: "Power generation is imperative." With the power plant, we can see clearly at night. In the future, I want to make electric lights available to every household in the Tang Dynasty, of course, this is a long process. It could take five, ten, or even fifty years. ”

"Oh, that's not a lot of 10,000 taels. We don't invest so much at once, it's only five million taels in the early stage, okay, I'll do whatever Brother Li says. Zhu Youneng was interested, and he wanted to put a hundred electric lights in his Guangwang Mansion in the future.

Li Ji didn't tell him that in the future, if he had electricity, he would be able to make media and television, and he could wait, Li Ji suddenly thought of a good thing.

"Okay, Brother Zhu, I still have to leave beforehand." Li Ji was in a hurry, and slipped away like a burning buttocks, leaving Zhu Youneng with a messy face.

After returning to the palace, Li Ji instructed Youwei: "Go, go and call me Li Baoguo and those bachelors in arithmetic!"

Youwei didn't dare to slack off, and hurriedly went out of the palace. These bachelors of mathematics are all scientific research talents of Datang, and they have a lot of research in various fields.

These people are all national treasures of the Tang Dynasty and are treated very highly. Anyone who is from a science of arithmetic will be treated according to the three-grade master, which can be described as infinitely beautiful.

Soon Li Ji summoned these scientific research talents to the Ming'an Palace, and they didn't know what was going on, which made Li Ji so anxious.

"I have decided to set up a radio station in the capital, so that every household in the capital can use the radio."

Radio, the ministers look at each other. They have only seen it from the materials brought by Li Ji, but no one has achieved practical research so far.

Li Baoguo asked timidly: "Your Majesty, should we let it go for a while, there are many important things that need to be dealt with at the moment." When there are conditions in the future, it is not too late to do this. ”

Li Ji looked very excited: "What are you waiting for, I will do this." It's just that the radio station is a little troublesome, you don't have to worry about it, this is left to me to protect the country, you pick a few talents who have some research on radio, and you can be dispatched at any time. ”

Li Baoguo frowned with a sad face, these are just seen from the data, what kind of sound wireless short wave and other things, how can anyone be a research talent in this area, and he didn't dare to not, so Li Baoguo chose a few.

Back at the Lizheng Palace, Li Ji was very excited. was so excited that Zhang Wanxi couldn't help but ask, "Your Majesty, why are you so happy?"

Li Ji laughed: "Wanxi, do you think the TV is good?"

Zhang Wanxi was taken aback, and hurriedly ordered those palace maids and eunuchs to go down, and only Li Ji and her and two children were left in the Lizheng Palace: "Your Majesty is crazy again, such words can be leaked casually."

"What are you afraid of, they don't understand anyway." Li Ji found a chair and sat down: "I am bored and bored here at night, and I have nothing to do except review and review. But in our modern age, there are a lot of fun things, and the most boring thing is to sit at home and watch those soap operas. ”

Zhang Wanxi deeply understands this, although those TV series are shot with anxiety and thunder, it is really good to use them to pass the time: "But Your Majesty, we don't have a TV here." Even if there is, you don't scare others to death if you take it out. ”

Li Ji smiled: "We don't have a TV, we can make a radio." Although this radio station is relatively cumbersome, the radio is simple. I remember when I was a child, there was an ore radio in the yard, and I didn't need a battery, I could listen to the radio just by plugging a ground wire into the ground. ”

What Li Ji wanted was to build a radio station, and the broadcasting equipment could be returned to the modern lane. The key is the popularity of radio, you can't get a million radios back from modern times at once, it's too ostentatious, and the system may not be able to get it back.

And the ore radio solves this big trouble, and you can make this kind of radio in Datang yourself.

First of all, ore radios are easy to make and do not require batteries. It is the simplest radio receiving device, mainly used for the reception of medium-wave public radio broadcasting.

Only one paper tube, one variable capacitor and one normal capacitor are required. The capacitor glaze factory has been able to make a Gu type, a high-impedance headphone, this is not very difficult, as long as you are willing to make it, Datang has the ability to make it, and you can also use ceramic speakers); An ore is used for detection. There are also a lot of wires, which Huangling Mountain has. And then there's some enameled wire. With just these few materials, you can make an ore radio.

When Zhang Wanxi heard this, she was also quite expectant: "Your Majesty, is there really anything to be done about this matter?"

"Why can't you do it, I must make it for you to see!" As soon as he finished speaking, Li Ji sat down and slapped his forehead: "Oops!"

Zhang Wanxi smiled: "Isn't it that simple?"

was said to be in his mind, Li Ji was a little depressed: "Yes, I just want to build a radio simply, but I forgot to generate electricity."

That's right, even if the radio transmitter Li Ji can be brought back from modern times, the radio station needs electricity.

You can radio without batteries, but radio stations do. At the moment, the only way to do this is to generate electricity first, and with electricity everything can be solved.

Thinking of this, Li Ji strengthened his determination to build a power plant.

A thermal power plant was built outside Luoyang City, and now trains have been laid in Huangling Mountain and the capital. A large number of coal mines and copper and iron are extremely convenient to transport, and the coal is transported to generate electricity easily.

Kaiyuan Cabinet Fang invested 5 million taels of silver, and the thermal power plant was put on the construction agenda. With electricity, the night in the capital will be more lively.

In a few decades, Datang will have everything. Although it can't catch up with modern civilization, at least it's about the same as the beginning of the last century.
