Except for Xu Qilin, no one knows where the historical trajectory of the Tang Dynasty would go in the next decade, during the reign of His Majesty Li Er.

With the variable Li Sipang, although history has changed, the overall environment around the Tang Dynasty has not changed much.

Xueyantuo in the north of the desert, Goryeo in the Liaodong, and Western Turks in the Western Regions were the three great enemies of the Tang Dynasty.

But in comparison, the Western Turks could cause some trouble to the Tang army in the Western Regions, but it was already sunset, and 20,000 to 30,000 Tang troops and vassals were enough to deal with it.

As for Xue Yantuo, although Li Simo's troops, who served as buffering and early warning, would not play much role, it was not so easy for Xue Yantuo to travel from the north of the Mo.

Perhaps, His Majesty Li Er had already lined up his soldiers and was waiting for Xue Yantuo to attack him from afar, and gave Xue Yantuo a heavy blow at his doorstep, making him unable to recover!

Therefore, Goryeo in Liaodong is the enemy that His Majesty Li Er wants to fight the most. Not only Xu Qilin saw this, but many ministers also guessed it.

To conquer Goryeo, two conditions need to be met.

One is money, food and materials, which consume more than several times more than the conquest of Gaochang; the other is an excuse, which is famous for its establishment, and in ancient times, this was very particular.

Many people, including His Majesty Li Er, did not expect that Dayingku would become an institution that would make money every day and would become the engine that promotes the historical process.

In fact, it is correct to make money every day in Dayingku. But it is obviously not enough to rely on such an institution to accumulate funds to mobilize the masses.

But there is Xu Qilin in Dayingku, and there is a book printing shop below. The "Farmer Book" has been published nationwide and has been designated as a must-read by His Majesty Li Er, and he also asked the local officials to supervise and guide the people to follow suit.

Just this method of fertilizing fertilizer will at least make three or five kilograms per mu of land?

Don’t underestimate these three or five kilograms of grain, it’s up to how much land there is in the country. According to historical data, the amount of cultivated land in the early Tang Dynasty was about 200 million mu, and the extra grain would be around 1 billion kilograms.

It doesn’t have to be so full. Take half of the output to increase, and the excess grain is about 500 million jin.

It has been three or four years since Xu Qilin launched the encyclopedia-style "Agricultural Book". Even if the first two years were digested and absorbed by officials, it was a very astonishing number only counted in the next two years.

With the development of the Western Regions of Longyou, Hexi and the continuous reclamation of the south, the amount of arable land has continued to grow, and the benefits brought are enough to support the Tang army to continue to fight against the outside world.

In addition to the establishment of Shanghai Pass, the extension of Dayingkudi Store increased, the opening of the Silk Road, and the entire Datang trade was driven, resulting in the continuous increase in the revenue of the treasury.

"As long as the money is enough and the food is high, the country will be able to maintain long-term stability." His Majesty Li Er sipped the fragrant tea and said earnestly to his fat son who was studying government affairs, "If the people do not increase their taxes, the country can use their full power. If you can do this, why worry about the country being unstable?"

Li Sipang was flipping through the statistical reports of the Ministry of Revenue in recent years. When he heard his father speak, he hurriedly sat upright and listened carefully.

The truth is very simple and clear. Who would rebel if the people can eat enough, even if they can't starve to death? And the Chinese people are the most patient.

"The child remembers the teachings of the father and the son." Li Sipang bowed and said, "The conquest of the unjust minister Gaochang, and the relief of the Wei River flood disaster refugees, the court has sufficient money and food. All of them are the father and the emperor is wise and has a good rule of the country."

His Majesty Li Er smiled faintly and said, "Qingque, why don't you say that I have also built the Daming Palace?"

Li Sipang hurriedly said, "The terrain of Tai Chi Palace is low and wet. The dragon body of the father and emperor is related to the country of the Tang Dynasty. What's more, the construction of the Daming Palace did not use the money of the states to rule the entrusted by the officials, nor did the salaries of officials be reduced, nor did the people pay the people. It has never been possible to build a large number of buildings without expending the people's money."

His Majesty Li Er stroked his beard and said, "Building a large-scale construction without expending the people's money. Your words are critical, but not complete."

After pausing, His Majesty Li Er explained, "There must be something that is to be exhausted, but not to let the people serve, but to hire them normally. Therefore, the people do not realize that they are suffering. There is no need to hide the damage to their wealth, but they do not add taxes and use the treasury, but use the money of the royal palace."

Li Sipang was in Luoyang at that time and did not know the situation very clearly. After hearing His Majesty Li Er's explanation, he suddenly realized and nodded repeatedly.

Isn’t the money from the royal palace earned by Dayingku?

Thinking of this, Li Sipang felt that he could take the opportunity to say a few good things to Xu Qilin, and then said, "The Royal Inner Government has no major business, but Dayingku is doing a good job and making a lot of money."

His Majesty Li Er laughed and said, "That's right, most of the money used to repair the Daming Palace is indeed from the Dayingku. Qi Lin's method of making money is impressive. Just that mirror makes more than a few million yuan."

Li Sipang couldn't help but be surprised. Millions of coins were just earned by the mirror used for surfing and dressing. It was the first time he learned the details.

His Majesty Li Er saw the fat son's surprise and said slowly, "Don't just look at the sales of mirrors in Chang'an. Before the Gaochang was captured, the mirror had been sold overseas through Yangzhou and Guangzhou. The profit was so huge that it was astonishing. When it was opened in the Western Regions, the mirror was the most popular and a large amount of revenue."

"It turned out to be sold overseas." Li Sipang exclaimed, "This child is unknown. I only count it as a result of my country in the Tang Dynasty. In fact, I have made a lot of money."

"The huge profits of the sea trade are indeed what you would never have expected." His Majesty Li Er did not blame his fat son. He was also shocked when he got the data report.

After pausing, he said slowly, "You have a good relationship with Qi Lin, and you should get closer in the future. From the perspective of age, you can also use it."

Li Sipang nodded and agreed, saying, "My son understand."

His Majesty Li Er sighed, "It is rare to be a capable minister in finance. From ancient times to the present, there are not many people who can leave their names in history. It is said that money is bad, but what can you do without money? You should also feel about this when you govern in Luozhou, right?"

"If you don't have the family, you don't know how expensive it is. When my son was in Luozhou, I had this feeling." Li Sipang said, "If you don't have money, you will have to work hard for the people, and my son is not afraid to do it."

His Majesty Li Er nodded and said, "There is also the immortal chief Lu Yu who can guide Qi Lin, which is his fate. Such an outlier must be respected even more."

Li Sipang thought for a while and said, "I heard that the old god Sun Simiao is coming to Chang'an. I wonder if it is true or false?"

His Majesty Li Er narrowed his eyes slightly and said, "This is true. I have asked someone to tell Qi Lin that he should not leave Beijing."

Li Sipang couldn't help but be stunned. It was indeed a big deal for Sun Simiao to come to Chang'an, but what's up to Xu Qilin? Why don't he allow him to leave Beijing?
