A national letter was placed in front of Zhao Han.

By the time the Datong army sailed to Korea, Mandahae had already withdrawn. This goods looted Seoul, and many people in Seoul were arrested as people's husbands to help transport the looted goods.

Li Zheng landed near Pyongyang by ship with thousands of men, biting off only one of the Manchu tails.

There was also a harvest, killing hundreds of soldiers, rescuing more than 4,000 Korean prisoners, and the goods transported by these people.

The Korean lord Yi Ju was placed under house arrest, and the prince Yi Hao became self-reliant in a coup d'état, and quickly won the support of the North Korean government and people. It was really Li Liang's performance that was so bad that the North Korean officials and the people complained about him, maybe another king could live a good life.

After Li Hao succeeded to the throne, he was doing three things:

First, under the banner of "full of Zhongxing", he purged his old ministers who did not obey him.

Second, he asked Li Zheng's Datong army not to leave and to be stationed in Baozhou in the future. Anyway, there is no one there, and the Manchu Qing Dynasty has grabbed ten rooms and nine emptiness. After the Datong Army was stationed, the North Korea supplied grain and grass in the first year, and in the second year, the Datong Army recruited displaced people to reclaim and replenish supplies.

Third, he asked the Emperor Daedong to canonize and give the king of Korea the golden seal.

Baozhou, located on the south bank of the Yalu River, was a bridgehead built by the Liao State to attack Goryeo, and it was also a necessary place for the Manchu invasion of Korea.

As long as the Datong Army is stationed in Baozhou, North Korea will be able to sit back and relax, and Li Hao will be able to manage internal affairs with peace of mind.

Zhao Han looked at the national letter in his hand, and couldn't help but smile dumbly: "This new lord of North Korea was full of wisdom when he usurped the throne, why didn't he know that it was easy to invite God and difficult to send God?" Invite the Datong Army to station, and allow the Datong Army to recruit displaced people for reclamation on its own, so you are not afraid of losing the entire Baozhou from now on? ”

Li Banghua felt strange about Zhao Han's thoughts: "Your Majesty, the two countries have diplomatic relations, and they should be benevolent to big things and small things. North Korea bathed and indoctrinated, and it has been a Chinese barrier for generations. At this time, North Korea is in trouble, and it trusts China, how can a great power in the Celestial Empire take advantage of the danger of others? Does Your Majesty still want to occupy Baozhou or not return it? Putting aside the big things and small things, North Korea has many mountains and few lands, and it has always been poor and remote, and even if it is occupied, it is useless. If the North Korean military and civilians resist, the time will be spent in North Korea, and the levy of food will not be enough for the army. ”

"Haha, it's me who thinks too much." Zhao Han instantly solved his doubts.

Neither the king of North Korea, Yi Hao, nor the current Li Banghua thought that China should occupy the territory of Korea.

Moreover, Li Banghua has explained the reasons, which are divided into two aspects: political public opinion and actual pros and cons.

No matter how high-sounding the reason Zhao Han found, as long as he invaded and occupied Korean territory in the future, it would cause the Korean monarchs and ministers to deviate from morality, and the scholars on the Chinese side would also think that Zhao Han was "immoral".

In that dilapidated place in North Korea, not only the weather is cold, but there are also many mountains and few lands. If there is resistance from the North Korean military and civilians, most of them will become a loss-making business, and the cost of maintaining the rule will certainly remain high.

Jeju Island was an exception, when Cho Han needed to raise horses.

Pang Chunlai didn't say much, he was too familiar with Zhao Han. Just listening to what Zhao Han just said, he knew that he would definitely expand in Korea in the future, and after making a decision, it would be useless for anyone to advise.

Zhao Han ordered: "Order the Ministry of Rites to arrange the canonization of the king of Joseon." Ordered the military department, requisitioned peasant soldiers, and trained the 14th Division of the Datong Army. The soldiers of the 14th Division gave priority to the selection of peasant soldiers who already had wives, had no children, and were not only children. After the training was completed, after the summer grain was harvested, the officers and men of the 14th Division, their husbands and wives went to Baozhou to settle down. ”

Li Banghua looked surprised, and he also understood that Zhao Han really wanted to invade Baozhou in North Korea.

Baozhou is on the border with North Korea, and it has long been empty. The officers and soldiers of the Datong Army, if both husband and wife go, after all, they will become the main population of Baozhou.

Zhao Han continued: "Order the officials, select the officials, and go to Baozhou with the army. After the officials went to Baozhou, they tried to recruit Korean refugees and give them land to settle down. By the way, how can people not have surnames if they also give surnames to the peasants of North Korea? ”

Li Banghua wanted to advise, but he didn't bother to say anything more when he heard this.

There are officials, troops, immigrants, and they can also recruit Korean refugees to divide their own households. In just three or five years, Baozhou will become essentially Chinese territory, and the king of Korea will not be able to recover it if he wants to—there is no cost of encroachment, so why not do it?

Li Banghua was not a broad scholar, and he would support the harmless business even if it violated Confucian morality.

Zhao Han said: "Baozhou is adjacent to the territory under the jurisdiction of the puppet Qing Dynasty, as long as the food there can be self-sufficient, our army can send troops from North Korea at any time. When the time comes, it will be a three-way attack on the pseudo-Qing Dynasty, all the way from Shanhaiguan, all the way from Gaizhou, all the way from North Korea! ”

Tian Younian praised: "The pseudo-Qing Dynasty must take care of one and lose the other." ”

Zhao Han also said: "The northern army is also insufficient. Ordered the military department, recruited peasant soldiers, and formed the 15th Division. Henan and Shandong are short of food, and after the 15th Division is trained, it can be stationed in Xuzhou first, and if there is a war, it will immediately be dispatched to the north. ”

In this way, the number of regular divisions reached fifteen.

Four divisions plus cavalry, 47,000 men and horses were piled up in Liaodong and Korea.

One division in Tianjin, one division in Dengzhou, and one division in Xuzhou. These 30,000 people can go to attack Liaodong, or they can be transferred to fight Li Zicheng at any time.

Four divisions were stationed in Henan, Hubei, and the southwest of Beizhili, mainly to guard against Li Zicheng.

Two divisions were stationed in Sichuan, one attacking Tusi in western Sichuan and the other in eastern Sichuan and western Xiangsi.

The two divisions were stationed in Guangxi, and after occupying the entire territory of Guangxi, they had to cooperate with the friendly forces of Sichuan to attack Yunnan and Guizhou.

The rest of the troops were either the emperor's own soldiers or the garrisons of important ports.

As for the garrison units in various places, all of them belong to the police establishment, and most of them recruit veterans and peasant soldiers. It is only stationed at the gate of the city, and the number is not very large, and if it really encounters a siege by bandits, the police of the whole city can be mobilized, and the peasants and soldiers on the outskirts of the city can also be quickly assembled.

Zhao Han's large-scale expansion of the army, in addition to making strategic preparations, was also to increase the promotion positions for the officers and soldiers, and also to arrange posts for those meritorious generals.

Li Zicheng nested in Shanxi, Shaanxi and Gansu, and there has been no movement.

According to the news transmitted by the frontline, the climate in the northwest this year was good, and Li Zicheng seized the opportunity to organize the households and the people, and a large number of peasants settled down to divide the fields and cultivate the land. More than a decade of drought and war has led to no land contradictions in the northwest, but has become too much land and too few people.

Li Zicheng didn't need to carry out land reform at all, and he could easily divide the land among the people.

The land in the northwest is thriving, and everything is improving. It's just that the officials are still greedy, only under the coercion of Li Zicheng, they are not as greedy as they were during the Chongzhen period, and the people can finally take a breath.

Many of the generals of Li Zicheng's rebel army have also become increasingly corrupt, and there are often cases of privately recruiting homeless people to work as tenants and hiding the civilian population. For this reason, Li Zicheng repeatedly ordered that he must not hide the population, and he has already killed several generals.

In addition to the development of internal affairs, it is to eliminate warlords.

A large number of troops were demoted to generals, and Li Zicheng intervened in the reorganization. If you don't obey, you will be beaten, and more than a dozen generals will rebel before and after, and all of them will be beheaded by Li Zicheng's troops.

In addition, last year, the Mongols invaded Shanxi from the border, and more than 20,000 Mongol cavalry moved south.

During the Xiaoice period, the grasslands were not having a good time. The Mongols had a difficult life, so they could only run to Shanxi to plunder, and were killed by Li Zicheng's Dashun army and fled.

Li Zicheng, who had so many things to do, naturally didn't have the time to come to fight Zhao Han.

Relations between the two sides are not bad, and even non-governmental trade has resumed. But everyone knows that on the side of the couch, how can others be allowed to sleep soundly, and the war between the north and the south is only a matter of one or two years.

Before the war between Dashun and Datong, there was also a possibility that the two sides would join forces to fight Gushi Khan!

Gushi Khan unified Qinghai and Tibet last year, which are bitter cold lands and must be developed outward. The army under the command of this cargo attacked Li Zicheng's Gansu while encroaching on Zhao Han's western Sichuan, and at the same time provoked Dashun and Datong.

Between a bunch of war information, Zhao Han finally received good news from industry and commerce.

"Your Majesty, grass ...... The minister has improved the warp bed. Xu Zhengming, who is committed to building helicopters, has produced results in less than half a year.

Zhao Han said happily: "Carry it in!" ”

Xu Zhengming's family has moved to Nanjing, and his eldest son is his work assistant, and he carries the prayer bed in with the guards.

The weaving process is complex, taking textile cotton cloth as an example, there are many procedures to do: ginning (deseeding, making cotton soft), spinning, warping, sizing, weft insertion (weaving).

Warping is the first process of spinning cotton yarn into cotton cloth.

Xu Zhengming pointed to the car in front of him and said, "Improving this is much easier than making a flying chair." Today's warp wheels are only eight (reels), and there are twenty spinning wheels improved by the minister! ”

"How many people do I need to do it?" Zhao Han asked.

Xu Zhengming said: "Two people. ”

The eight-way warp car is also operated by two people, and the production efficiency has been increased by 2.5 times.

The textile industry of the Ming Dynasty is very different from the north and the south.

The north is still using the tooth rake type warping, and the south is using the axle frame type warping in the Song Dynasty.

When weaving cotton cloth, the axle frame type warping has better quality and greater output.

The axle frame warping technology in the south initially used a dial and only one retractor (a basket). By the middle and late Ming Dynasty, a bed had been invented, with four wire takers.

The birth of Jiangxi's water conservancy spinning machine stimulated the development of spinning machines in Jiangnan.

So two years ago, the craftsmen of Jiading County invented a warp bed with eight silk takers. Now, Xu Zhengming has improved the warp bed again and expanded the number of wire takeers to 20.

Zhao Han just stimulated and encouraged the invention and improvement of the warp bed in advance.

In the original history, in the middle and late Kangxi period, Chinese craftsmen made 30 warp beds with silk takers. Compared with a retractor in the early Ming Dynasty, how huge the development is, you can intuitively understand it from the numbers.

Zhao Han asked, "Can we continue to improve?" ”

Xu Zhengming scratched his head and smiled: "Yes!" Give the minister another year or two, and he will definitely be able to turn the warp bed into thirty or fifty years! ”

"His ambition is commendable!" Zhao Han praised.

In the development of textile machines, all processes need to be improved, Xu Zhengming only improved the warping process, and there is still a long way to go.

Once the steam engine was introduced, existing technological inventions could be installed on the steam engine.

Zhao Han asked, "How did you improve it?" ”

Xu Zhengming was puzzled: "Is it difficult?" That's it. The previous menstrual bed, at a glance, you can understand how to change. ”

Zhao Han was speechless for an instant.
