I

A letter of credence was placed in front of Zhao Han.

When the Datong Army sailed to North Korea, Man Dahai had already withdrawn. This guy looted all of Seoul, and many people in Seoul were arrested as civilian husbands to help transport the looted goods.

Li Zheng took thousands of people and landed near Pyongyang by boat, only biting off a part of Manqing's tail.

There are also gains, killing hundreds of soldiers, rescuing more than 4,000 Korean captured people, and the property transported by these people.

The leader of North Korea, Li Ji, was placed under house arrest, and his eldest son, Li Hao, became self-reliant in a coup, and quickly won the support of North Korean officials and people. It is really that Li Zhen's performance is so bad that North Korean officials and people complain about him. Maybe another king can live a better life.

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

First, under the banner of "filling up ZTE", purge old officials who do not obey you.

Second, I asked Li Zheng's Datong Army not to leave, and to be stationed in Baozhou from now on. Anyway, there was no one inhabited there, and the Man Qing robbed ten rooms and nine empties. After the Datong Army was stationed, North Korea provided food and grass in the first year, and the Datong Army recruited refugees to cultivate supplies in the second year.

Third, ask the Datong Emperor to confer the title and bestow the golden seal of the King of Korea.

Baozhou is on the south bank of the Yalu River. It was the bridgehead built by the Liao Kingdom to attack Koryo, and it was also the only place where the Manchu Qing invaded North Korea.

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

Looking at the letter of credence in his hand, Zhao Han couldn't help laughing: "The new ruler of North Korea was full of wisdom when he usurped the throne, so why didn't he know how easy it is to invite the gods and send the gods away? Invite the Datong army to station, and allow the Datong army to recruit on their own." Are you not afraid of losing the whole Baozhou from now on if the refugees colonize it?"

On the contrary, Li Banghua was surprised by Zhao Han's thoughts: "Your Majesty, the two countries have diplomatic relations, and we should treat great things as small things. North Korea has been bathed in enlightenment, and it has been China's fence for generations. At this time, North Korea is in trouble, and it trusts China. How can the great power of the Celestial Dynasty take advantage of the danger of others Does Your Majesty still want to occupy Baozhou and not return it? Leaving aside the theory of big and small matters, North Korea has many mountains and little land, and has always been poor and remote, so it is useless to occupy it. North Korea uses troops, and the grain and taxes collected are not enough for the army’s expenses.”

"Haha, I was overthinking." Zhao Han immediately cleared up his confusion.

Neither King Li Hao of North Korea nor Li Banghua in front of him thinks that China should occupy North Korea's territory.

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

No matter how high-sounding the reason Zhao Han finds, as long as he invades the territory of North Korea in the future, it will cause the North Korean ruler and ministers to be alienated, and Chinese scholars will also think that Zhao Han is "immoral".

In that poor place in North Korea, not only is the weather cold, but there are many mountains and few lands. No food can be grown even if it is beaten down. In case of resistance from North Korean soldiers and civilians, it will probably become a loss-making business, and the maintenance cost of the rule will definitely remain high.

Jeju Island was an exception. At that time, Zhao Han needed land for raising horses.

Pang Chunlai didn't say much, he was too familiar with Zhao Han. Just listening to what Zhao Han said just now, he knows that he will definitely expand in North Korea in the future. After making a decision, it is useless for anyone to persuade him.

Zhao Han ordered: "Order the Ministry of Rites to arrange for the canonization of the King of Korea. Order the Ministry of War to recruit farmers and soldiers to train the 14th Division of the Datong Army. The soldiers of the 14th Division are given priority in selecting soldiers who have wives and no children for the time being. Farmers and soldiers with only one son. After training, after the harvest of summer grain, the officers and soldiers of the 14th Division, husband and wife will go to Baozhou to settle down together.”

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

Baozhou is on the border of North Korea, and it has long been empty. Datong army officers and soldiers, if both husband and wife go to settle down, will definitely become the main population of Baozhou.

Zhao Han continued: "Order the Ministry of Officials to select officials and go to Baozhou with the army. After the officials go to Baozhou, they try their best to recruit Korean refugees and give them land to settle down. By the way, we also need to give surnames to North Korean farmers. How can a person not have a surname?"

Li Banghua wanted to persuade him, but he didn't bother to say anything after hearing this.

There are officials, the army, and immigrants, and they can also recruit Korean refugees to organize households and sub-fields. In just three to five years, Baozhou will essentially become Chinese territory, and the king of North Korea will not be able to take it back even if he wants to - there is no cost of encroachment, so why not do it?

Li Banghua is not a pedantic scholar, he will support the beneficial and harmless business even if it violates 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. At that time, there will be three routes to attack the Puppet Qing Dynasty, all the way from Shanhaiguan, all the way from Gaizhou, and all the way from North Korea. !"

Tian Younian praised: "The puppet Qing Dynasty must pay attention to one thing and lose another."

Zhao Han also said: "The army in the north is also insufficient. The Ministry of War is ordered to recruit peasants and soldiers to form a new fifteenth division. Henan and Shandong are short of food. After the fifteenth division is organized and trained, it can be stationed in Xuzhou first. In case of war, immediately Send north."

In this way, there will be fifteen regular divisions.

Four divisions plus Xiao cavalry, 47,000 troops were piled up in Liaodong and North 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.

The 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 to attack the chieftains in western Sichuan, and the other to attack the chieftains in eastern Sichuan and western Hunan.

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

The rest of the troops were either the emperor's personal soldiers or the guards of important ports.

As for the city defense forces in various places, they all belong to the police establishment, and more veterans and farmers are recruited to serve. They are only stationed at the gate of the city, and the number is not very large. If bandits attack the city, the police in the whole city can be mobilized, and the peasants and soldiers in the suburbs can also quickly gather.

Zhao Han's large-scale expansion of the army, in addition to making strategic preparations, is also increasing promotion positions for soldiers, and assigning positions to those who have made meritorious deeds.

Li Zicheng nested in Shanxi, Shaanxi and Gansu, and has been quiet.

According to the news sent back from the front line, the weather in the Northwest is good this year. Li Zicheng seized the opportunity to register as a household of Qimin, and a large number of farmers settled down and divided their fields for reclamation. More than ten years of drought and war have led to conflicts in the Northwest where there are no people, but instead there are too many lands and too few people.

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

The land in the northwest is actually thriving, and everything is getting better. However, the officials are still greedy. Only under Li Zicheng's coercion, the greed is not as strong as in the Chongzhen period, and the common people can finally breathe.

Li Zicheng's uprising troops, many generals became increasingly corrupt, often privately recruited refugees to farm and hide the civilian population. For this reason, Li Zicheng made repeated orders not to hide his population, and he had already killed several generals.

In addition to developing internal affairs, it is to eliminate warlords.

A large number of soldiers and generals were surrendered, which was reorganized by Li Zicheng. If you don't obey, you will fight, and more than a dozen surrendered generals rebelled, all of which were beheaded by Li Zicheng's troops.

In addition, Mongolia invaded Shanxi from the border last year, and more than 20,000 Mongolian cavalry went south.

During the Little Ice Age, the grasslands were not easy. The Mongols had a difficult life, so they could only come to Shanxi to plunder, and were defeated by Li Zicheng's Dashun Army.

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

The relationship between the two sides is not bad, and even resumed non-governmental trade exchanges. But everyone knows that other people are not allowed to sleep soundly on the side of the couch, and the war between the north and the south has only been a matter of one or two years.

Before the war between Dashun and Datong, there is also a possibility that the two parties will join forces to defeat Gushi Khan!

Gushri Khan unified Qinghai and Tibet last year. These are places of bitter cold and must be developed outward. The army under this guy harassed Li Zicheng's Gansu, while encroaching on Zhao Han's western Sichuan, and at the same time provoked Dashun and Datong.

Among the piles of war information, Zhao Han finally received good news from industry and commerce.

"Your Majesty, grass... I have improved the scripture bed." Xu Zhengming, who devoted himself to building a helicopter, produced results in less than half a year.

Zhao Han happily said: "Bring it in!"

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

The weaving process is complicated. Take cotton weaving as an example, there are many procedures to be done: cotton ginning (removing seeds and making cotton soft), spinning, warping, sizing, and weft insertion (spinning).

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

Xu Zhengming pointed to the warp wheel in front of him and said, "Improving this is much easier than making a flying chair. Today's warp wheel is only eight (screw collectors), and the spinning wheel that I have improved is a full twenty!"

"How many people are needed to operate?" Zhao Han asked.

Xu Zhengming said, "Two people."

The Baxian classic car is also operated by two people, and the production efficiency has increased by 2.5 times.

The textile industry in Ming Dynasty was very different from the north to the south.

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

Cred warping for better quality and greater output when weaving cotton.

In the southern creel warping technology, the dial car was used at the beginning, and there was only one yarn taker (Yi 繀). By the middle and late Ming Dynasty, the bed was invented, with four wire collectors.

The birth of the water conservancy spinning machine in Jiangxi stimulated the development of the spinning machine in the south of the Yangtze River.

So two years ago, craftsmen in Jiading County invented a warp bed with eight silk collectors. Now, Xu Zhengming improved the sutra bed again and expanded the number of thread collectors to twenty.

Zhao Han just stimulated and encouraged, advancing the invention of the menstrual bed.

In the original history, in the middle and late Kangxi period, Chinese craftsmen produced thirty sutra beds for silk collectors. Compared with a thread collector in the early Ming Dynasty, how huge the development is can be intuitively understood from the numbers.

Zhao Han asked: "Can you continue to improve?"

Xu Zhengming scratched his head and smiled innocently: "Yes! Give me another one or two years, and I will definitely be able to turn the sutra bed into thirty or fifty!"

"His ambition is commendable!" Zhao Han praised.

With the development of textile machines, every process needs to be improved. Xu Zhengming only improved the warping link, and there is still a long way to go.

Once the steam engine comes out, the existing technical inventions can be installed on the steam engine.

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

Xu Zhengming asked doubtfully: "Is it difficult? It was changed just like that. You can understand how to change the previous menstrual bed at a glance."

Zhao Han was speechless for a moment.
