After resolving the bandits, whether from the perspective of stabilizing personal power or considering the Ming Dynasty, Yang Sichang had to control the Jurchens outside the country.

In December of the second year of Chongzhen, Huang Taiji personally led a large army, led by Mongolian troops, and took the Mongolian army. He divided into three groups into Xifengkou and entered the pass directly to the capital. It was not until the fourth year of Chongzhen that he retreated outside the pass. This time, the surrounding area of ​​the capital was destroyed, Man Gui died in battle, and Yuan Chonghuan was cut into pieces. This battle greatly affected the face of the Ming Dynasty, making Zhu Youjian always think about seeking revenge for the Jurchens.

In the seventh year of Chongzhen, Huang Taiji entered the pass again, and his troops divided into four groups to attack the Ming Dynasty, invaded and destroyed, looted a large number of people and property, and then returned to Shengjing.

In the ninth year of Chongzhen, Huang Taiji ascended the throne and became emperor. He ordered Ajige to go straight to the capital, trapped more than ten cities, and plundered 180,000 people and animals to return to Shengjing.

Time and again, the Ming Dynasty capital was in danger, and Zhu Youjian became increasingly unable to tolerate the Jurchens showing off their power under their noses. Yang Sichang suspected that if Zhu Youjian saw the Jurchens riding horses and galloping under the capital city again, would he be cut into pieces like Yuan Chonghuan?

Consistent with Lin Chunhong's view, Yang Sichang clearly realized that all of this originated from Huang Taiji's conquest of North Korea and Mongolia. North Korea was designated as a country that was not conquered by Taizu, and fought side by side during the Wanli period to drive the Japanese into the sea. The two sides had strategic seeking each other, and the alliance was absolutely certain. However, since Huang Taiji conquered North Korea, the Jurchens completely eliminated their worries. Since then, the Jurchens have unscrupulously attacked Mongolia and the Ming Dynasty, and their strategic advantages have become increasingly obvious.

As for Mongolia, although it did not form an alliance with the Ming Dynasty, it was obviously impossible for the Jurchens to attack the Ming Dynasty's hinterland through Mongolia. Therefore, Mongolia can be regarded as the natural barrier of the Ming Dynasty. However, since Huang Taiji conquered Mongolia, the Xuanda defense line of the Ming Dynasty was full of flaws, giving Huang Taiji the opportunity to take advantage of the situation.

In Yang Sichang's plan, to solve the problem of the Jurchen invasion, we must start from these two aspects.

Yang Sichang's goal was not high. He believed that as long as the Jurchens could be prevented from breaking through the Xuanda defense line and the Ningjin defense line, even if they achieved the goal. As for directly attacking Huanglong and completely destroying the Qing Dynasty, Yang Sichang obviously had not lost his mind yet and would not do such a crazy move.

In history, once nomadic peoples and fishing and hunting people established grammar, they would become strong enemies of the Central Plains court. For example, Liao, Xixia and later Jin and Mongolia in the Northern Song Dynasty. In the early Ming Dynasty, Taizu and Chengzu Xiong were very talented and obviously saw this. They kept sending heavy troops to attack the Northern Yuan, which was still grammar at that time, and they broke the Northern Yuan into pieces. They didn't write grammar before they could stop.

As expected, although Mongolia has often posed a threat to the Ming Dynasty for more than two hundred years, it obviously belongs to the category of border troubles and has not yet risen to the level of importance of a heart-to-heart trouble.

Now Huang Taiji not only established grammar, but also became the sovereign and lonely. It is not easy to completely destroy the Qing Dynasty and regain Liaodong?

Yang Sichang was preparing to start from Mongolia and North Korea, take a two-pronged approach to gradually reverse the strategic unfavorable situation and ultimately achieve the goal of defending the enemy outside the country's borders.

Losing Liaodong, the land connection between North Korea and the Ming Dynasty had been completely cut off. If you want to go from the rear of North Korea to threaten the Jurchens, you can only go through sea routes. Yang Sichang considered that Lin Chunhong's power was too large and he was unwilling to promote Lin Chunhong everywhere, so he placed his hope on Zheng Zhilong. However, Yang Sichang learned about the sea situation in detail and thought of the bad records of Zheng Zhilong refusing to rush to Jinzhou. He finally turned his attention to Lin Chunhong.

During this period, Yang Sichang used all his tricks, just to reach a certain degree of tacit understanding with Lin Chunhong, so as to avoid strategic misjudgment between the two sides and bring disaster to the court. This tacit understanding includes Lin Chunhong's troops pointing to North Korea, attacking from the rear, and weakening the Jurchens' strength.

Regarding Mongolia, Yang Sichang intends to win over Mongolia again. However, Huang Taiji has been in Mongolia for a long time and has formed a solid alliance with many Mongolian tribes through large-scale marriages. It is even more difficult to get involved. However, Lin Chunhong's large-scale acquisition of wool in Datong and Xuanfu made Yang Sichang's eyes lit up and felt a little enlightened.

Under the trend of economic interests, the so-called marriage is just a joke, and this is a truth that will never be broken through the ages.

However, at present, only Lin Chunhong can turn the acquisition of wool into a business that is not a loss, and others cannot imitate it. What's more, it will take decades to pass this path before it will have a decisive role. How could Yang Sichang have so much time to wait?

All Yang Sichang could do now was to invest a lot of money to train the Xuanda Border Army after destroying the bandits in the territory, stabilize the Xuanda defense line, and prevent Huang Taiji from running to the capital to show off his power.

Yang Sichang sighed and turned his thinking back to his eyes from the long-term plan.

From Li Shaoyi's secret letter, Yang Sichang learned that Lin Chunhong wanted to surrender Zhang Xianzhong and Luo Rucai, and was preparing to place the bandits in Luonan County. He could see at a glance that Lin Chunhong wanted to push Xiong Wencan to the front desk to enhance his influence on the court's political strategy.

Lin Chunhong wanted to reach into the center of the Ming Dynasty. Although Yang Sichang could not accept it emotionally, he was a little expectant from the rational point of view.

After Yang Sichang took over the power of the court, what was most annoying was that the bureaucrats shirking responsibility in everything, they did not have the ability to do things, and their ability to quarrel was first-class. Especially those censors, who would curse people all day long, like a bunch of fly, which made people want to slap them to death. Although Yang Sichang did not agree with Lin Chunhong's idea of ​​setting up a bureaucratic system, this did not prevent him from envying Lin Chunhong's subordinates for their outstanding abilities and high morale.

If these talented people can be introduced into the court, it will be of great benefit to the court.

Originally, after Yang Sichang's plan, after limiting the Jurchens to Liaodong, the next thing to solve was Lin Chunhong. Yang Sichang's understanding of Lin Chunhong's strength was much clearer than other court officials. He knew that it was the best to completely solve the hidden danger of Lin Chunhong. Not using weapons was the best strategy. Although Yang Sichang had not yet formed a specific strategy for solving Lin Chunhong, there was still a general direction, which was to gradually integrate the Jingzhou group into the Ming system and use the strength of Jingzhou for the court.

Giving Lin Chunhong the right to speak in the court, or directly allowing Lin Chunhong to hold important positions in the court can also be regarded as one of the effective means.

However, Yang Sichang just thought about it and did not dare to reveal a trace of his mouth. Yang Sichang suspected that as long as he revealed this meaning, the saliva of the censors and court officials would drown him.

Indeed, which of these censors and court officials, even local bureaucrats, has not been studied hard for many years and passed the exam? How could they tolerate Jingzhou, a group of wild guys who were born in a wild way, snatched away the already extremely scarce important positions?

Under such circumstances, it is a good way to make Xiong Wencan, who was born in the Ming Dynasty's bureaucratic system, hold a high position.

Yang Sichang did not object to Xiong Wencan, who was close to Jingzhou, to enter the cabinet, but Xiong Wencan, who was controlled by Lin Chunhong, entered the court, obviously was not within his tolerance.
