Feeding the most people with the least amount of land and manpower is the problem that Sun Xiangfu needs to solve after he is idle.

It's a pity that even if the Tang Dynasty conquers the four sides, he may not be idle, what will Lantian Vocational and Technical College teach after it is built? Engineering colleges, business schools, what will be taught after they are built? He didn't even care about the specific teaching after the construction of the agricultural college he was in charge of! I have to face a lot of inquiries.

However, there are still two restless little ones at home, and they always ask themselves why, which makes his work efficiency a lot reduced.

Li Chunfeng and Li Chengqian returned to Chang'an, and under the effect of the 160-fold magnifying glass tube, Li Chunfeng, who had seen a lot of microorganisms, had a lot of biological questions to ask Sun Xiangfu.

After he came to Sun's Mansion, he immediately used the telescope set up in the Sun's Mansion compound to look at the starry sky, and then he had a lot of astronomical questions to ask Sun Xiangfu.

Sun Xiangfu will not be stupid to directly help him solve what he knows, but guide him to find the answer by himself, the first thing to prove is that the world they live in is round, how to prove it?

Go sail around the globe and see if you can get back to the same place from the other direction!

Need a boat for sailing?

Then go to the shipyard and help build the ship!

This logic can very much make Li Chunfeng have no objections, so not only will there be one more mathematician on the shipyard's side, but the exploration team led by Zhao Long will also have one more astrological expert in the future, as well as a maritime medical team led by this expert.

Li Chengqian, on the other hand, boasted to Sun Xiangfu about how he had turned the five surnames and seven families around during his time in Shanyang.

"Teacher, haven't you seen that after learning that their family was deceived by the Wang family about blueberry planting, their faces, more than a year of hard work, huge investment, and wasted in vain, Lu Wenzhong was going to burn the Wang family's blueberry orchard on the spot, but the Wang family protected it very well, and set up an ambush to beat Lu Wenzhong half to death······

By the way, the Wang family wants to find someone to play after his father returns to Chang'an, release Wang Guizhong, and promote Wang Yao to be the crown princess, and the rest of the family will definitely obstruct it, and they are all ready to send their own women to the East Palace······"

"Well, their minds are still on you, and that's a better situation. The perception of your career experience in Shanyang should also be handed over to me, and when Your Majesty returns to Chang'an, I am afraid that you will be examined, you can answer truthfully, if you are allowed to go to the court to listen to the government, you must also be psychologically prepared. ”

"However, my career experience is not yet complete!"

Half a month of professional experience, from last year to now, there are only about 20 occupations, these experiences can only be said to have given Li Chengqian a lot of understanding of the current society, but it is not considered to have seen all the people.

Sun Xiangfu didn't think much about it and said, "Then continue to experience it in Chang'an!" ”

"Okay, just wait for your words, teacher."

It seems that Li Chengqian came to Sun Xiangfu's side mainly to accomplish this.

After Li Chengqian finished speaking, Sun Xiangfu reacted, this guy is afraid that he doesn't want to stay in the palace, but if he doesn't want to stay, he won't stay! Anyway, it's really not a good place to grow in the deep palace.

"By the way, teacher, I heard that Xiaotai has been tortured by you recently, and he is going to live or die." Li Chengqian, who was about to get up and leave, suddenly thought of something interesting and smiled at Sun Xiangfu.

"Nonsense, I'm doing this for his good, your mentality of watching younger brothers and sisters laugh is unacceptable, as an elder brother, you should always think about being good for them."

"Uh, I know, I know, I'll definitely continue to do good for them."

Li Chengqian ran out with a smile, Sun Xiangfu didn't bother to pay attention to him, Li Shimin's ship was about to arrive in Chang'an, there were many things to summarize for him, Sun Xiangfu had so many things to manage, and there were naturally many things to summarize, the key was that he wanted to summarize an effect, so there would be more thought to be spent.

After discussing the bereavement of the fallen soldiers, Sun Xiangfu discussed with several bigwigs in the military and made great reforms, at least not lower than the bereavement of the seafarers later. The key is to let the families of the fallen soldiers feel the continuous care of the imperial court, so the parents and minor children of the fallen soldiers will receive monthly subsidies from the imperial court.

In this regard, since the economic conditions of Datang allow, it can do better than that of later generations, and Sun Xiangfu's goal is to at least promote the country's social security services to meet or even exceed the standards of developed countries in later generations.

Then, when Sun Xiangfu finished all the summarization, he found that Datang's financial situation should be good, after all, he still knows some of the main consumption and main income, that is to say, the Ministry of Finance, at the end of the year, there should still be a large balance of money.

A big war that cost 20 or 30 million yuan actually took just over a year to recover, which shows how strong the economic strength of Datang is at the moment, and in the future, it may be even stronger, because the effect of the mission to the countries of the Western Regions is gradually reflected.

As the countries of the Western Regions learn more about the Tang Dynasty, their lords begin to understand that they can bring more benefits to themselves by conducting trade with the Tang Dynasty at a larger level, so many of the merchants from the Western Regions who came to Chang'an this year to sweep goods are coming on behalf of the country, and the total trade volume has increased significantly, reaching 23 million guan, an increase of 6 million guan compared with 17 million guan last year, and only in terms of exports, it has reached an increase of more than 30 percent, and there are more cash transactions converted into gold and silver. The net inflow of assets reached more than 1,000.

In this kind of transaction of exchanging goods for gold and silver, in fact, it is impossible to calculate how much Datang has made a specific profit, because as more gold and silver flow into Datang, its price will depreciate, and at this time, Datang actually needs a more precise and strict monetary management policy.

Therefore, after Sun Xiangfu came back from Li Shimin, the first thing he wanted to play was the currency reform.

In October, the entire Chang'an City under the organization of Fang Xuanling, began the work of wearing red and hanging colors, Emperor Li Shimin was going to return to Beijing with the power of conquering the four Yi, even the Emperor Li Yuan, he was invited out of the Changle Palace to greet, hundreds of thousands of soldiers with iron armor, all from the Longshou original school yard to tidy up the ceremonial outfits, directly from the Mingde Gate to the gate of the imperial city.

Therefore, when it comes to being the prime minister, Fang Xuanling is much smarter than Xiao Yu, he knows what kind of scene Li Shimin wants and what kind of scene the court needs.

In front of the Mingde Gate, all the officials in Chang'an, as well as the lords, ministers, princes, etc., thousands of people, bowed to Li Shimin three times, and walked along the straight Vermilion Bird Street to the imperial city with Li Shimin's car, under the condition of the people's gongs and drums and flowers and colorful silks.

In the imperial car, one left and one right, the old and new generations of emperors sat side by side.

Although Li Yuan had a faint smile on his face, no one could understand the complexity in his heart.

Li Shimin looked high-spirited, and with that momentum, he almost pointed at Li Yuan's nose and said, "Look, I am ten times better than you, and it is the most correct for Datang to hand over to me." ’

At the gate of the imperial city, the eldest grandson queen led a group of concubines, princes, and princesses lined up to greet each other, of course, they just came out to meet each other, Li Shimin will go directly to the Taiji Palace, preside over the court meeting, among the princes, because there is no adult, only the crown prince Li Chengqian is qualified to participate in this court meeting.

Then, Sun Xiangfu finally knew why the Ministry of Finance deliberately left a large amount of money, because the Taiji Palace, where there are usually only more than 100 people in the court, cannot stand up to thousands of courtiers.

Not to mention that there are now more than 200 officials above the fifth rank in the ten ministries in Beijing, and there are three or four hundred generals above the fifth rank in the expanded military general sequence alone. In addition, there are hundreds of high-ranking officials at or above the level of local state assassins sent by the governors of various prefectures. There are also kings, princes, ministers, senior generals who lead the troops of more than 20 countries who have surrendered, and there are hundreds of people, which leads to the fact that more than half of all the people who need to be seen are directly lined up outside the main hall to blow the cold wind.

There is no way, indoors, there is only enough for a few hundred people to stand, and the courtiers can't be crowded shoulder to shoulder!

This situation made Li Shimin's brows furrowed, and on his face, there were almost a few big words written on his face, 'I want to expand the palace', but there are a lot of things to be announced today, but those courtiers below the fourth grade have to stand and blow the cold wind for a few hours.

Li Shimin's announcement to the world has a lot of content, first of all, it is to declare the territorial sovereignty of the newly included in the Tang Dynasty, and now all the places occupied by the Tang Dynasty, including the islands where Feng Ang has set up boundary monuments overseas, the Australian mainland, etc., have all been named by him and written in the edict, and the people in these territories are also regarded as the people of the Tang Dynasty and can apply for the protection of the Tang Dynasty.

The reason why he did this was because he had been to the sea, and he knew more specifically how big a dot on the map, the size of a broad bean, was actually there.

Secondly, he once again reaffirmed the power enjoyed by the people under the rule of the Tang Dynasty, as well as the responsibilities that should be assumed, although these things, those ethnic minorities who can't even understand Chinese, or overseas barbarian peoples, will be impossible to understand for a while, but the surface work of the imperial court must be done first, as for the specific household registration, and the implementation of the same management as the Han people, it may take many years before it can be slowly implemented.

Third, it is a reward for the meritorious soldiers of the Eastern Expedition, the Western Expedition, the Southern Expedition, the Tuyuhun and the Expedition of the Party Division.

In this kind of military merit, the first reward, must be the general who fought to kill the enemy on the front line, therefore, Zhang Gongjin, the Duke of Zou Guo, who actually participated in the most battles, was the first meritorious, moved to the Duke of Liao, worshiped the Governor of Andong, the second son of Yin, the Duke of the Third Son, rewarded with 10,000 taels of silver, 1,000 horses of silk, and the rest of the various rewards, too many to count.

Second, he actually arrived at Sun Xiangfu, you know, in the whole process, although he did not participate in the battle, but he played a crucial role, first of all, to ensure the new equipment of the entire army, as well as the supply of grain and grass.

Then, it was a strategy to water it into ice, so that Li Shimin easily took the fortified city of Goguryeo.

The biggest credit, of course, is the battle of Yanpingmen in Chang'an, although more than half of the credit for this battle should be distributed to Fang Xuanling, who promoted the entire plan, as well as Du Ruhui and many other ministers left behind in Chang'an, and more than two million people in Guanzhong, but the initiator is Sun Xiangfu.

Therefore, although Sun Xiangfu did not directly kill the enemy on the battlefield to obtain military merits, his merits also ranked second, however, Li Shimin did not move his title, but added him the title of Doctor Jin Ziguanglu, and directly shaded the title of the Duke of Fengyanguo, the unborn third son, the Duke of Shanyang County, and the second daughter Sun Wanyu, the title of the lord of Hong'an County.

The reason why he was directly crowned to the level of the Duke of Guogong was because he was the duke of Shanyang County before, and letting him take the last step on the title can be regarded as a compensation for Li Shimin's contribution to Sun Xiangfu in the south, which is equivalent to giving the Sun family a duke title in vain.

Moreover, it also has the meaning of motivating him to give birth to a son quickly, because the third son was born and was the title of Duke of Shanyang County.

As for the rewards of other gold and silver property, they are almost the same as Zhang Gongjin, it can be seen that although Li Shimin ranked Zhang Gongjin first, in fact, in his heart, Sun Xiangfu's credit is even greater, because Sun Xiangfu's reward is actually heavier than Zhang Gongjin's.

There is also this kind of honor, there is Cheng Biting Jin, this guy won more than a dozen countries in the Western Regions, a territory of thousands of miles, and the credit is not small, while he served as the governor of Anxi, the second son Cheng Chuliang, the young son Cheng Chubi, all sealed the county duke, the concubine Cheng Chu Cun and Cheng Chuli, and sealed the county.

After that, it was the credit of the commander of the front army, Hou Jun Jiyin was the duke of a son, Li Jiyin was a duke of a county, Qin Qiongyin was a duke of a county, Niu Jinda was promoted to the Duke of Lu, Dugu Mou was promoted to the Duke of Xingguo, and Shelong was promoted to the Duke of Yunnan.

Although Fang Xuanling, Li Jing, Du Ruhui, and so on did not directly participate in the battle, they were rewarded for their strategic planning and resourcefulness that played a key role.

In the end, it was Su Dingfang, a general at the level of merit, he was promoted to the prince of Pyongyang County, Cheng Mingzhen, Zhang Jian, etc. all had corresponding titles promoted, Xue Li, was named Yangwu County Hou, and even Chai Shao and Xiao Yu, two people who were in Shuzhong and did not complete the work perfectly, also received a certain reward.

When everyone thought that the internal military merit reward link was about to end, there was a climax again, Li Shimin broke the convention of reluctance to give up the official position above the second rank of the Tang Dynasty, and was named the general of Lingnan Province, and Feng An, the Duke of Yueguo, was the general of the hussars, and the opening of the palace was the same as the three divisions.

This made the sequence of civil and military officials in the Tang Dynasty, there was a living official at the level of first-class, and it was given to the officials at the level of the Sixteen Wei Generals, the Ten Shangshu and the Prime Minister, a higher level of pursuit.
