The area of the country itself is huge, and it is conservatively estimated that the administrative area of the area under its rule is not 6 million square kilometers, but there must be 5 million, the population is approaching 50 million, the population of the Sun Kingdom is nearly 13 million, and the slave society has a population of more than 60 million, and the additional population of more than 13 million will be a huge hidden danger to society, and it is very urgent to divide and dilute the foreign population as soon as possible.

Secondly, the aristocratic contradictions within the country forced the king to shift the focus of the contradictions outward, so that the domestic nobles could develop outward, so as to regain the domestic land and turn the internal struggle into external plunder.

Third, the three younger brothers of King Wei have become a climate, weakened but not collapsed, and diluting the population is an important means of weakening strength.

If the benefits are promised, especially from the outside, it can logically promote the outward flow of refugees, so as to alleviate the cost pressure of the country to digest the vested interests.

Many factors combined to prompt the defense to agree to release him.

However, Bailiyan did not worry about the problem of large numbers of people and refugees, and Ganfu, Dekang, Shangguan, Pengyuan and other places basically ended the war before August 640 of the Shengyuan Dynasty, and initially transferred to agricultural production in the autumn of that year, and Weiguo did not reach an agreement with Xianguo until the end of Shengyuan 641.

This means that the delivery of the four counties of Dekang, Yuanshan, Qiujun, and Mingtian will not be until the end of 643, and the Xianguo has a buffer of more than three years to sort out the clues and use it to mobilize national strength to prepare for the aftermath.

More importantly, in August 641, Yongxing City developed a "seed drill car" [Note 1], this kind of sowing on the top of the seed pot, under the ploughshare, with livestock traction, livestock in the front, people in the back of the cart, livestock pull the car at the same time, the seed pot automatically planted, according to the cattle, horses, donkeys can be configured according to the size of the different livestock livestock one-legged, two-legged, three-legged ploughshare car seed seeder, the use of convenience and high efficiency.

One person and one ox can easily cultivate 70 acres of land in one day, and one person and one horse can cultivate more than 50 acres, and the workload of one day is equivalent to all the land that can be cultivated by the manpower of two to three families in a quarter. The efficiency and speed are unprecedented.

As early as before the Han Dynasty in China, there were columbian carts, and until the end of the Qing Dynasty, they were still the main agricultural tools for automatic sowing.

However, the building car also has disadvantages, it can only be dry farming and can not be watered, and it requires animal power, and cannot be pulled by manpower, especially the paddy field that raises seedlings can not be transplanted with a cocoon car.

Therefore, the subtropical and cold zones can only be used for planting dry-fed plants in autumn and winter, such as wheat, beans, rapeseed, cottonseeds, etc.

In addition, the improvement of farming efficiency has not solved the problem of harvesting, which is still restricted by manpower and weather, but the emergence of columbs still alleviates the problem of eating.

Then before the autumn of that year, pig iron as the ploughshare, wood as the body, rushed to make more than 3,000 pieces of cocoon cars, priority sent to Pengyuan, Wanchuan, Shangguan, Ganfu Dekang and other places, Shengyuan 642 and then 40,000 pieces sent to various places, and used in Tuntian.

In the spring of 643, the grain shortage in Xianguo was basically lifted, and more than 1.8 million refugees fled to the east were resettled in the same period, and in the autumn of that year, the refugees reached a peak, and 400,000 people poured into the border in January.

Soon after the appearance of the cocoon, due to the simple structure and easy imitation, imitations appeared one after another among the princes of various countries around 644 in the Shengyuan Dynasty, and the agriculture of the Central Plains entered an era of unprecedented prosperity.

In the past two years, the pattern of the Central Plains has been initially determined, and the situation has quietly turned a new page in a stable manner.

On the ninth day of the seventh month of the Shengyuan Dynasty in 641, on a thunderstormy night, Wang Shuo died of depression in remorse at the age of sixty-five.

Before Wang Shuo died, he never forgot when Bailiyan was a teenager, and he took one last look at his unmarried son-in-law, but he would never have this opportunity.

Wang Yanfei died of a cerebral hemorrhage in January of the following year, which can be regarded as the end of his life and a good death.

The old man has gone to the newcomer, Zhou Kong married into the Yongxing Marquis Mansion in May 641, until September 642 gave birth to a daughter Bailiwan, so far, Bailiyan got the tenth daughter.

Because of this matter, after Yongxing Yicaotang opened a biology course, Bailiyan never mentioned the theory of genes for many years, and it is obvious that giving birth to ten daughters in a row can no longer be explained by science.

At the end of 643, the national strength stabilized and rebounded, and the grain storage in various places resumed normal growth, but Qianfang fell into a huge loss, with a deficit of more than 5 million new dollars, but the simple deposit continued to improve, and the actual expenditure of 680,000 inches of silver was actually spent at the beginning of the surrender and rebellion, and more than half of it was deposited in Qianfang.

The capital injections of Yongxing, Luhou, Xuanting, and the state treasury ensured a reasonable source of cash, and while the state treasury maintained a steady growth, the debts were transferred from the state treasury to the money square, and the money bank used depositors' funds to invest and raise funds abroad, relying on the state's credibility to guarantee the shortfall.

During the same period, the Xian army was successively reduced, repatriated, and resettled from the peak of 850,000 people, and the garrison army was changed to a town army, with a standing reserve of 350,000 people.

In addition to the capital city of Qiling, the auxiliary troops in the main cities and county towns ranged from 2,000 to 1,200, and at the same time, reserve troops were set up, and the battalions of the workers were converted from temporary workers to formal establishments, with 200,000 personnel.

The new military system makes it clear that the auxiliary soldiers in various localities are subject to the dual control of the imperial court and the local government in peacetime, and the military rations and grass for the auxiliary troops are changed from being raised by the local governments to be directly under the jurisdiction of the central government, so as to put an end to the malpractice of the aristocracy and the powerful colluding with the government to raise troops and gather thieves and bandits to oppress the localities.

The town army is not in the position of the general of the levy and town guard, collectively referred to as the general, the metropolitan governor remains unchanged, the left and right governors are changed to overseers, the left and right captains, the left and right commanders, the unified merger of the commanders, the commanders, the captains, the captains, the commander

At the same time, the system of professional soldiers and medium- and long-term compulsory soldiers will be implemented on a pilot basis, and the military salary received by professional soldiers is different from the basic military salary of compulsory soldiers, so as to retain the backbone of the army and encourage the seed of veterans to serve.

The reserve army is based on the county unit, but all men who have reached the age of 18 and are under the age of 40, who have no disability and no visual or hearing impairment, are reserve troops.

The reserve forces regularly organize two military training camps each year, each of which shall not be less than 20 days, and encourage the promotion of the spirit of martial arts.

Those engaged in non-agriculture, such as industrialists and merchants, handicraftsmen, students, craftsmen, etc., can be exempted from military training after being reported by the government to facilitate economic development, and will not be included in the first batch of conscriptions in wartime.

At the same time, in wartime, those who have a skill and academic background are not included in the conscription, so as to preserve the intellectual elite and technical class of society.

In order to ensure the effective development of military training, the armament battalion has been expanded from 4,000 to 12,000 personnel; on the one hand, military attaches and veterans who have been dismissed from various armed forces will be accommodated, and on the other hand, the expanded armament battalion will regularly send personnel to various localities to inspect military training, so as to maintain the effectiveness of the armament.

At the same time, a juvenile camp was set up to recruit young people between the ages of 13 and 18, and the number of applicants was not limited to each year, but in the end, only 200 people were selected to enroll, and from then on an institutionalized mechanism was formed to gradually realize the professionalization and specialization of military attachés. For those who are unsuccessful, those who are outstanding in one or more items can be guaranteed to enter the school for further study.

Under the new military system, officers and men at all levels of the town army, the forbidden army, and the armed battalion implemented the system of paying salaries, and the auxiliary soldiers only ate food and were not paid, but they could enjoy the treatment of the town army in wartime.

The maximum length of service for ordinary soldiers is 45 years old, and the number of veterans and officers is extended to 50.

The camp implements a three-year rotation system, implements quasi-military management, is busy with farming, and does not practice the system of stiptory, but the family members enjoy tax exemptions and exemptions.

After three years of service in the battalion, they are demobilized and allowed to return to their hometowns and join the reserve army according to their own wishes, forming a regular rotation system.

First, long-term confinement of people in camps is not conducive to the natural growth of the population, and regular rotation is conducive to the healthy development of the population.

Second, on the basis of the labor camp, we will eradicate illiteracy, popularize advanced agricultural technology and concepts to the young people in the labor camp, accelerate the popularization of advanced agricultural technology, and promote the injection of agricultural talents from all over the country.

The work of disarmament and reorganization began in the second half of 641 and was basically implemented by the end of 643, and many military attachés at all levels were promoted.

Zhao Xun Jin Yongxingjun, hereditary replacement, Nuo Yiyan worships the middle doctor, Gao Xun worships the middle doctor, and the rest of the people have been promoted to varying degrees.

Regarding the disposition of Gongsun Yue, the king of Yintian, Gongsun Yue has always shown people with a mask, and there are very few people who know the inside story.

In order to cooperate with the disarmament, the king of Yin Tianzi asked to reduce his post and retire to the mountains and forests, and the king of Xian allowed him to retire.

In 644, Gongsun Yue died of severe rheumatic bone disease, and his protégé Gong Shouqian and his family were secretly placed in Suidang to guard Gongsun Yue's spirit until his death.

After that, the king of Xian spent 30,000 inches of gold, 150,000 inches of silver, 650,000 new dollars, more than 50,000 pearls, more than 1,200 pieces of jade, 25 pieces of ivory products, more than 40,000 pieces of silk, silk, silk, brocade, Luo, yarn, and silk, 300,000 pieces of cotton cloth, and more than 20,000 sets of other novelty items of the Xian Kingdom.

The number of rewards and the extravagance of the items are unprecedented in the hundreds of years of foundation of the founding of the Xian country. Ranked first among the princes of various countries, it greatly boosted people's morale.

In the same year, the newly occupied land was straightened out, and the rest of the country was relieved, and the king of Xian urged the excavation of the mausoleum, and after two years of preparation, Baili Yanteng also took action to readjust the policy of governance, change the center of economic work, and began to open three disciplines: physics, chemistry, and pharmacy.

After several years of training and development, the talent base of Yongxing City is gradually taking shape, especially the development of mathematics has gradually entered the family situation, and many of the contents that Bailiyan had previously ignored and omitted have gradually surfaced, and have been conquered and improved by Yongxingcheng University Hall and the Ligong School, and extended to other fields, especially many people have realized the combination of mathematics and natural physics.

To this end, Bai Liyan selected 150 people between the ages of 16 and 40 who had higher mathematical attainments from Yongxing City and Ligong School in two years, and it is worth mentioning that after Su Fangyi lived in Yongxing City, he tried his best to persuade Yuke to send apprentices to Yongxing to learn mathematics and skills, and twelve of the first two batches of recruits were from Yuke.

Due to the fact that chemistry is the lifeblood of the military economy, Bailiyan only opens physics courses and basic chemistry principles to Yuke and Gonggong in one direction, and pharmaceutical and medium chemistry are only taught to reliable children in Yongxing City, especially about explosives.

[Note 1] The rapid dry farming seed drill that appeared in the Han Dynasty enabled China to achieve large-scale agricultural cultivation. It was not until the mid-nineteenth century that Europe obtained samples of the technology of cocoon from China, which led to the registration of patents in Europe and the realization of the agricultural of cereals.

The principle of modern mechanized seed drill is still the product of the re-optimization of modern technology and mechanical design.

However, without the blessing of high-yield non-grain crops such as potatoes, corn, and sweet potatoes, Europe would first industrialize and then agriculturalize, and follow a deformed development of putting the cart before the horse, and its basic agriculture could not support the huge industrial population and raw material demand, and bloody colonization and slavery were inevitable results.

Since it could not be agriculturalized, it did not have enough agricultural wealth, material and human resources, to feed a large number of people who were out of agricultural production, such as students, scholars, teachers, judges, navy and army, industrial production population, miners, workers, bureaucracy, and so on.

At the same time, potatoes and sweet potatoes were restricted by the restrictions of modern storage technology at that time, including modern storage technology, and could only be eaten in season, and it was difficult to store them for a long time like cereals, so potatoes and sweet potatoes still did not fundamentally solve the agricultural problems in Europe before the twentieth century.

A large number of non-agricultural people need to be supported by a large agricultural system, so that they can engage in production, labor, scientific research, study, order and even war outside of non-agricultural production.

Therefore, when agricultural output cannot maintain the human resources, mineral raw material resources, human resources, social resources, and even political stability and military security required for industrialization, it will inevitably embark on the road of bloody colonization and enslavement.

However, the import of high-yield crops such as potatoes, sweet potatoes, and corn has to a certain extent made up for the shortcomings of the early non-agricultural and pre-industrialization of the West.

The emergence of the Chinese Han Dynasty only solved the problem of planting, but not the problem of harvesting, and harvesting is more labor-intensive than planting.

A person with a sickle can cut more than one acre of land in a day, and a woman may only have five or six points of land, so although the cocoon car solves the problem of planting, it does not solve the problem of harvesting.

Therefore, if the Chinese dynasties can solve the problem of harvesting, many problems will not be a problem.
