Not long after Li Yuan left, Li Shimin returned.

This time, he brought a lot of gifts. It's not to thank Boss Ye for the spaceship he built, but Li Chengqian's apprenticeship.

Boss Ye really doesn't know what to do in elementary school, but since someone gives a gift, he can't push it out; Boss Ye, who was reluctant to accept a few large boxes of apprenticeship, reluctantly agreed to the complicated apprenticeship; A set of etiquette is Sun Xin's responsibility, as a scholar, he attaches great importance to etiquette.

However, Boss Ye was troublesome, and repeatedly asked to simplify the process, and finally after some tossing, he accepted Li Chengqian's apprentice.

Ye Jinyu didn't take apprenticeship seriously, but for Li Shimin, it was equivalent to forming a community of interests similar to Ye Jinyu's in-laws, and the relationship between the two families instantly changed from passerby to intimacy.

No, after the apprenticeship, Li Shimin asked Ye Jinyu for advice on the matters that need to be paid attention to in the Eastern Expedition.

Fighting, especially the war in the era of cold weapons, Ye Jinyu doesn't understand this thing; However, Li Shimin didn't want to ask him about the war.

"The places that the Eastern Expedition passes through are all outside my Tang Dynasty; Although Xiao Wang sent scouts to go, the mountains are high and the forests are far away, so he has not received too many replies for the time being; I also asked King Shenxiao to teach me how to deal with all the way to Muzhou, soldiers, horses, grain and grass, road traffic, indigenous people and other miscellaneous things. After arriving in Muzhou, how to ensure that the follow-up immigration channels are unblocked? ”

Some of the scouts sent out earlier by Li Shimin have already returned, but the information they brought back is somewhat outdated; And the spies further away have not heard from them yet, and I don't know if they are still alive. The expedition is imminent, and Li Shimin, who is black-eyed, can only find Ye Shenren, the provider of the map.

It's just that the Eastern Crusade is a big proposition, starting from Chang'an, all the way to the east, through the Northeast, through the Far East of the Polar Bear, across the Bering Strait, and all the way to the American Road; Don't mention it far away, let's talk about the nearest Northeast! Although it is a great country of the motherland, Ye Jinyu has never been there, for the impression of the Northeast, he has only learned in history books, where the industry is developed, FAW, Shen Huoyi such as the birthplace of national enterprises, is the eldest son of the republic's industry. The Chinese books of the elementary school also said that this was a roe deer scooping fish, and the pheasant flew to the North Okura in the rice pot.

Well, everything is the impression of modern society, but what is the situation in the Northeast on the Tang side? Ye Jinyu didn't know anything, maybe, maybe, maybe Nagada was purely a bitter cold place, maybe the people who were pushed over to develop there were equivalent to exile in disguise.

Why is there such a big difference between the modern Northeast and the Northeast of the Tang Dynasty, and why can the modern Northeast become an industrial base and an agricultural granary? Ye Jinyu felt that there was no other reason, it was because of someone!

The large-scale population of the Central Plains entered the Northeast from the time of my Great Qing Dynasty, and after the fall of the old Zhu family and the Ming Dynasty, my Qing Dynasty had a short period of Liaodong recruiting people to reclaim, and introduced a large number of people from Guannei into the Northeast; However, only more than 20 years later, in order to protect the dragon vein of the Qing Dynasty, Kang Mazi's immigration policy was stopped forever. Contacts between inside and outside the customs were severed.

After nearly two hundred years, there are evil neighbors in the north who are eroding outside, and natural disasters are constantly occurring inside; It was only in the Qing Dynasty that the ban on reclamation was lifted, and the people in the customs were allowed to go out of the customs to break into life; During this time, many people who couldn't survive went through the Kanto region.

By 1949, when the first city tower was established, there were already 40 million people in the Northeast; It is precisely by relying on these 40 million people, coupled with the mineral resources and old industrial foundation of the Northeast, that the Northeast has become the eldest son of the Republic of China.

What is the concept of 40 million people? According to the Book of Sui, in the second year of Emperor Yang of the Sui Dynasty, there were 8.9 million households in the country and a population of 46 million. At the peak of the Sui Dynasty, there were only more than 40 million people in the country; After the war in the late Sui and early Tang dynasties, the population of the country dropped sharply, and there were only more than 2 million households in the Wude period; After more than 20 years, in the thirteenth year of Zhenguan, the number of households in the country was 3.04 million, with a population of 12.3 million.

This is still more than ten years later, that is to say, the current Datang has a smaller population. Of course, after conquering the Turks, hundreds of thousands of castrated slaves and tens of millions of women and children can be harvested; These are also counted in the total population.

However, this is still the total population of the country, and it is impossible for the emperor to support Li Shimin with all the soldiers, so the population that Li Shimin can mobilize is at best the military strength of Tiance Mansion, as well as some people in the rivers and lakes who are not willing to be ordinary. As for the number, Ye Jinyu pessimistically believes that it will not exceed 500,000!

As mentioned earlier, the current Tang Dynasty, whether in terms of economy, military, technology and, most fundamentally, population, has no capital for external expansion in a short period of time; Li Yuan's family proposed such a huge expansion plan, which is also the product of their own plans and compromises. I won't talk about these antecedents, but let's discuss the actual expansion plan.

Even if there are powerful spaceships, artillery and other advanced weapons that can easily defeat the enemy, if there are no people stationed in the place for a long time, it will still be lost after a long time. There is a reference for this style of play, that is, the Mongol Empire established by Temujin, the Mongol light cavalry that swept through Europe and Asia, seemed invincible in the world, and coerced all kinds of people to lay down a large territory, but the shortcomings of the Mongolian population could not control such a large place at all, and could only rely on the locals; In the end, it will inevitably fall apart for a while.

Speaking of which, it is still a problem of underpopulation. It is still necessary to encourage more childbearing and raise more babies; then improve hygiene to ensure the survival rate of infants; After dozens or hundreds of years, after several generations of hard work, the problem that plagued Li Shimin was solved.

The only problem is that Li Shimin is about to go on an expedition, and it is impossible to wait for dozens or hundreds of years.

"King Qin, this road to the east is actually easy to open, there is a spaceship god thunder to bomb, those Goguryeo people or other natives will be frightened, and then use infantry to rush, any kind of city can be heard. The trouble is that when the army crosses the border to Muzhou, these defeated places are not garrisoned, and sooner or later they will fall into the hands of the natives, thus threatening the follow-up traffic. ”

Ye Jinyu said, Li Shimin nodded in agreement, he also knew this, what he needed was a way.

After reviewing the brains of those group members in the black technology group, combined with the practice of white colonization of the world, Ye Jinyu continued:

"Since the territory that has been fought cannot be held for the time being, do not divide the troops to occupy it; After the army fought all the way by land, only left some strongholds and castles in suitable places along the coast, you must know that long-distance transportation, taking land is not as cost-effective as water transportation, you see the Sui Emperor repairing the Beijing-Hangzhou Grand Canal; And river transportation is not as cost-effective as sea transportation; After all, when the canal is repaired, it often requires a lot of manpower and material resources to repair and maintain. And the sea does not need to be maintained; ”

"The subsequent transportation of materials and soldiers can be completely by sea. First, leaving strongholds and castles only needs a small number of elite troops to defend them, unlike the elimination of the country, which requires a large army to suppress the bomb, save troops, and deal with the natives You can also pull a group of bounty hunters, a scalp is one or two silver, and a million natives only need one million taels of silver! In addition, there were numerous strongholds and castles that provided docking supplies for subsequent seafaring ships, allowing them to carry more supplies and less food and water. In addition, these strongholds and castles can be used as bases to exchange goods and obtain information from the local natives. Later, when the population of the stronghold increases, it can be used as a base to expand inland. Make noodles with points and slowly eat whale swallows. ”

Whether it is a stronghold or a scalp, these are all common tactics used by white colonization, Ye Jinyu thinks that if the white people do it, why can't the Tang people do it; Borrow and use first.

"If you want to continue to gain the population of the Central Plains, it is not feasible to rely on coercion, which will only make people deviate from morality, and it can be completely induced to benefit; There are many gold mines in Muzhou, and you can use gold mines to lure some unproductive rangers to pan for gold. "How attractive the gold rush is, there is a lot of black history in the Eagle Sauce family.

"In the north, near the sea, you can fish and produce salt; You can also make salted dried fish from salt and fish; Dried salted fish can be used as a source of meat and salt. "This is hearsay in the black technology group.

"Of course, these are only expedient measures, and in the long run, we should still send people to the south...... the water island, which found those high-yielding crops and came back, increased food production and fed more people; Where there is a population, there is everything. ”

Li Shimin listened quietly, he was very smart, there were many things needless to say, he also understood; It's just that I haven't figured it out for a while, and I don't need to explain it in detail, just click on him to understand it. The only one who can't see through and can't figure it out is the Ye Shenren who has been in constant turmoil.

After Boss Ye said his thoughts, Li Shimin said: "King Shenxiao is really a word for the country, but it doesn't matter if it's a stronghold or a castle; It's a long time. Xiao Wang thought that if he built more floating spaceships, with the load and speed of the spaceship, he could reach Muzhou from Chang'an in a few days, without the need to travel thousands of mountains and rivers. Even if you need a stronghold on the way, you don't need too much! ”

This Li Shimin has a good idea, and Ye Jinyu said in his heart that I also know that the spaceship is excellent.

"But I only have four slipways here, and I can build four big ships a month at most; I can't build too much in a year! "We also have to face the difficulties of power supply shortage and power generation equipment shortage.

Li Shimin listened, but said, "Why does King Shenxiao want to trap the Shenren Fang? Xiao Wang went to Henan Road, recruited shipwrights and carpenters all the way, and built three or five slipways in Henan Road, and it was easy to build ships! This matter can not be known by the saint, and the spaceship Xiao Wang is willing to increase the price twice to buy it from the Shenxiao King. Can it? ”

Ye Jinyu was stunned when he heard this, and his feelings said that he was staying to ask for advice, but in fact, he didn't want to come up with his own ideas at all, but purely wanted to hide from his father to engage in arms smuggling. This Li Er, think a lot! No wonder he was able to kill the eldest brother and the third brother, and then ousted his father from the throne.
