The development of things has actually exceeded Li Yuanjing's expectations, in fact, he doesn't want to leave Datang, otherwise he wouldn't have engaged in so many industries in Chang'an before.

As a prince, isn't it good to use the identity of the royal family to make money in business and become the richest person in the Tang Dynasty?

But later experience taught Li Yuanjing that some things are not what you want to do.

Although Li Shimin did not show any dissatisfaction now, Li Yuanjing faintly felt it.

I have to go, and I have to do it as soon as possible.

The longer it stays, the deeper the roots, and the deeper the roots, the greater the impact.

Even if Li Shimin has never been suspicious of himself, what if one day Li Shimin's physical condition is not good?

At this time, in order to ensure the stability of his son's throne, will he kill his brother, who is not bad?

The family is a living example, because the days of multiplication are too long, and the family size is so large that Li Shimin can't easily move them, if he hadn't proposed the overseas king plan, the solution to this matter would still rely on the bloody battle decades later.

It is now July of the seventh year of the Tang Dynasty, and Li Yuanjing has been resting in Chang'an for almost five months.

The reform of the professionalization of the armed forces has already achieved initial results, and Li Shimin has also attached great importance to the first victory after the reform.

The military general sent Li Jing, the Duke of Weiguo, Li Shimin actually didn't want to use Li Jing, the credit of the Northern War to destroy the Turks was too great, if he also made a contribution in the south, it would be a little difficult to deal with in the future.

Li Jing actually didn't want to come out, but Li Shimin considered that this time it was the prince who went out in person, and he, who was a father, didn't equip him with a few trustworthy generals, what if something went wrong?

As for Li Jing, Li Shimin had no choice but to add him to the list of kings.

In addition, Li Shimin also sent another general, Duan Zhixuan, the Duke of Fan Guo, who was not as famous as Li Jing and others, both of whom were veterans who could fight well, and there was no problem with their abilities.

Of course, things are far from being so simple, in addition to these two generals, Li Shimin also seconded the eldest grandson Wuji, who was in charge of the affairs of the East Sea Province, back as the prince's nominal military advisor, but the eldest grandson Wuji has something to do recently, and he needs to wait a month before he can go to Jiaozhou.

"How many accounts does Datang have at present?" On the vast sea, Li Yuanjing sat on the deck and looked ahead and asked.

That is, there can be such a comfortable day in the near sea, and when you reach the depths of the sea, the waves are not so gentle, and the waves that are two or three meters high are considered gentle there.

"Uncle Wang, the population of Datang has nearly tripled in the past two years!" At the mention of the population of the Tang Dynasty, the expression on Li Chengqian's face instantly became excited.

There is his credit for this, although this credit is not large, but Li Shimin still adopted some of his suggestions, and follow-up observations also learned that his suggestions were effective.

"The number of households has increased to nearly 6 million, and the population has reached nearly 30 million! According to the statistics of the previous dynasty, there should be about two million households in the imperial court analysis, and 10 million people are still in a state of seclusion, so this part of the population will be the next focus! ”

Li Yuanjing nodded, the statistics of Emperor Yang of the Sui Dynasty were nine million households, five million people.

After experiencing the turbulent times at the end of the Sui Dynasty and some natural disasters, the current population attrition of one million households and 10 million people given by the imperial court should be relatively reliable.

Even if later generations experienced the short history of the War of Resistance Against Japan, on the basis of a population of 400 million, the loss exceeded 50 million.

Li Yuanjing did not think that the impact of the chaotic times at the end of the Sui Dynasty could exceed that of the War of Resistance against Japan, nor did he think that the fighting here was more intense than that period.

Even considering all kinds of problems, Li Yuanjing even felt that the number of people lost might not exceed 10 million.

But this is not something Li Yuanjing should worry about.

This time, the fleet was accompanied by 30,000 navies from the Haizhou army to the imperial court, and these people will be scattered all over Lingnan as the backbone, and it will take a year to help them adapt to it.

The road is far away, there is nothing to do on the sea, and there are no enemy forces that can compete with the Tang Navy during this period.

Idle is also idle, Li Yuanjing decided to continue to train Li Chengqian.

"What is the arrangement for those who have escaped from seclusion?" Li Yuanjing asked.

"Most immigrants, a small part will get the land returned by the family, but the government military system has already existed in name only, so Cheng Qian is considering whether the uniform field system will also be changed?" Li Chengqian boldly put forward his own idea, which he did not dare to put forward lightly in front of Li Shimin, at least after argumentation.

"Why?" Li Yuanjing suddenly said curiously.

"Although the original intention of the Juntian system was good, after so many years, has it finally become the current situation? If a family is gone, will there be a new family in dozens or hundreds of years? Will the soil of land annexation resurge?

If one day there is no suitable place for the king overseas, what should be done with these people? Therefore, Cheng Qian thinks that there is no problem with the use of the uniform field system in the short term, but if it is used for long-term goals, it will never be able to change this fate! Li Chengqian said seriously.

"How do you want to change it?" Hearing that Li Chengqian was able to think of such a far-reaching question, Li Yuanjing couldn't help but be interested.

Of course, he was aware of the drawbacks of the Juntian system, and although various systems were constantly changed in the following millennium, the land problem was still the biggest problem facing China.

It was not until the founding of the People's Republic of China that this problem was initially solved, but it was not really solved.

In fact, it was not until after the reform and opening up that the agricultural problem entered a turning point, and it was truly resolved in the coming decades.

"Uncle Wang's policy in Tamna made Cheng Qian quite touched, the biggest wish of the people in this life is to be able to eat and dress well, in this case, can the imperial court gather the land, everyone to cultivate together, in addition to the annual output for their own use, the rest of the storage part for backup, the other part for military use?" Li Chengqian said.

Li Yuanjing's forehead instantly wrinkled into a line, this is such a proper rhythm of big pot rice.

It's not that it's bad, it's okay in a short time, but after a long time, the problem appears.

"People's desires can not be satisfied, when a person is not full of food and clothing, his greatest ideal is to be able to eat enough, to be able to have new clothes to wear, when he can eat enough and warm, his ideal will become a meal to eat meat, when he can eat meat at a time, he will want to make his life better, so that his children can receive a better education.

For example, if you want to sit on the throne of the emperor now, what about after you sit on the throne of the emperor? Your goal must be to find a way to govern Datang beyond your father, and when your ability surpasses your father's, you will definitely find a way to bring Datang to a new level, these are all human nature......"
