Because of the emergence of Zhu Youzhen and the embargo policy against Jin implemented by Zhu Youzhen, the original historical North Korea suffered another round of military oppression by the Jin State in the first year of Chongzhen.

The king of Joseon was forced by the military pressure of the Jin State, and had no choice but to form a vassal relationship with the Jin State, and from the vassal state of the Ming Dynasty, he completely became a vassal state of the Jin State, which was eight years earlier than the original history.

In this regard, Zhu Youzhen asked the cabinet to issue a stern rebuke statement against the DPRK in the name of the Ming Dynasty, and no longer recognized the vassal relationship of the DPRK.

In this regard, the king of Korea was extremely aggrieved, and on the one hand, he was committed to the obscenity of the Jin State, and on the other hand, he secretly sent an envoy to contact the Ming Dynasty, telling him that it was not easy, hoping that the Ming Dynasty would forgive him, and send Wang Shi to land as soon as possible to drive away the invaders.

Zhu Youzhen was quite unimpressed with the attitude of the DPRK on the surface, but secretly he relied on Donggang Town and the newly formed North Sea Fleet to support the activities of the Korean people in resisting the aggressors.

For the Manchurian Jurchens, from the king to the common people, there were a hundred people in Korea who looked down on them, except for a few traitors who forgot their ancestors, most of the low-level people still hoped that the Ming army could help Korea drive out the Jin State like the anti-Japanese war during the Renchen period.

Even when they heard that Yang Hao of the Ming Dynasty was back in charge of the war in Liaodong, many Korean people rejoiced, looking forward to Inspector Yang helping the Korean people to restore their country again.

For the hearts of the people in North Korea, Zhu Youzhen is very grateful to his titular grandfather, the Wanli Emperor who has a problem with his feet and does not like the previous dynasty, twice aided the DPRK to fight against the Japanese, and laid a friendship between the Ming Dynasty.

Therefore, with the benefit of Zhu Youzhen, Dongjiang Town secretly accepted the Korean righteous soldiers who were unwilling to accept the rule of the Jurchens, organized and trained them, distributed weapons, and formed a Korean resistance army.

After the training was mature, with the help of the ships of the North Sea Fleet, it was sent to the Korean Peninsula, and wave after wave of Korean righteous soldiers came to Donggang Town, compiled the training, received food and weapons, and embarked on the journey to fight the invaders.

In North Korea itself, there are personnel from the Jinyiwei Intelligence Service to guide them in various anti-aggression activities.

Although the force was relatively weak and the restoration of the country was far away, it still caused a lot of losses to the Jurchen army stationed in Korea, the most obvious being Amin, who presided over the Korean expedition, was pinned down in Korea and did not dare to move.

The corresponding Eight Banners Army was also contained in North Korea, which was not found in the original history, and being able to contain Amin's Eight Banners Army shows that Zhu Youzhen's North Korean strategy was successful.

In addition, under Zhu Youzhen's instructions, the Jinyiwei Intelligence Department and Dongjiang Town also instilled the ideology of the Huaxia family in the trained Korean righteous soldiers, cultivated pro-Ming forces, and laid the groundwork for Zhu Youzhen's strategy toward the DPRK in the future.

In addition, unlike the strategy toward Korea, because the Mongolian ministries are still a relatively independent force that cannot be underestimated, Zhu Youzhen can only adopt a strategy of bundling interests and actively wooing them.

With the help of Hudun Rabbit, the nail planted by Zhu Youzhen on the grassland, we know that in June of the second year of Chongzhen, the Mongolian tribes still did not completely fall to the Jurchens, especially Mongolia west of Xuanfu.

Moreover, Zhu Youzhen also relied on the Hudun Rabbit Department to reopen mutual trade in Mongolia and take the opportunity to collect some swinging Mongolian tribes.

Zhu Youzhen also knew that this would allow some materials to flow into the Jin Kingdom, but there was no perfect law in the world, and for the sake of strategic layout, some tactical losses were also acceptable.

Moreover, with the improvement of spinning looms, the scale of Xishan woolen mills has expanded, and the demand for Mongolian wool has increased significantly, which has given Mongolian ministries to see business opportunities.

Although forced by the Jurchen deterrence, these Mongol tribes did not dare to do business with the Ming State in a big way, but through Hudun Rabbit or directly and secretly sent envoys to contact the Ming Dynasty, the trade volume between the two sides increased month by month.

With the establishment of the Xishan Woolen Mill, the wool from the grassland was made into thick carpets and woolen tweeds, which were transported to the rich places in the south through the Tianjin seaport and the Tongzhou Canal wharf, and even through the coastal trade of Fujian, Zhejiang and Guangdong, and sent to the world.

The delicate silk, fragrant tea, salt, rice and cotton from the south came to Gyeonggi through the Tianjin port and the Tongzhou Canal Wharf.

Gyeonggi left rice grain and distributed it to all parts of the northern Ming Dynasty, while cotton was spun and woven in Xishan and then sent to all parts of Daming.

The silk, tea, and salt from the south, as well as cotton cloth and felt from the western mountains, would be left in tents on the grassland through the mutual market.

Through the trade of wool, salt, and tea, the Ming Dynasty had established direct or indirect trade with most of the Mongolian tribes, which made the Mongolian strategy of the Jin State slow to achieve the expected goal.

Besides, the Jin State also needed this trade route to replenish the blood, and it did not dare to pinch it too tightly, and when the Mongolian tribes were not strangled, the Jin State starved to death first.

Since the trade with the Ming and Jin merchants was cut off a lot, the Jin State has been counting on this Ming-Mongolia-Jin trade chain.

Although there is the existence of the Mongolian tribes, the Jin country has suffered a lot, but it can only break its teeth and swallow it in the stomach, if it is robbed openly, those shrewd Mongolian nobles will not be profitable, and it is estimated that they will not do this business.

They may also completely fall to the Ming Kingdom in the south, leaving them with no chance of breaking their teeth, and they can only starve to death with their teeth empty.

In this regard, with the wisdom of Huang Taiji, he naturally sees it very clearly, but this is a clear hand, and there is nothing to be done about it.

All Huang Taiji could do was to encourage farming at home, improve the treatment of the Han people, and reduce the use of the military aristocracy of the Jin State, in order to achieve the goal of self-sufficiency.

But this goal is so difficult, at this time the Great Northern Wilderness has not been developed, although the land of the Liaohe Plain is fertile, but because of the climate can only be planted for one season, plus the impact of the Xiaoice period, either drought or frost.

The northern part of the Ming Dynasty is nine disasters in ten years, not to mention the Liaodong region, where the climatic conditions are even worse.

Therefore, although Huang Taiji has worked hard, in order to encourage agriculture and improve the treatment of Han people, he even did not hesitate to break out with the domestic military aristocracy many times.

The Jurchens at the bottom were even more dissatisfied, and in a year's time, there were two riots, in order to establish authority and consolidate the rule, Huang Taiji even aimed the butcher's knife at his own people, which calmed down.

Of course, forced by the need for stability, although Huang Taiji knew that these two riots were driven by people at the level of Baylor, he did not dare to rashly expand the scope of the attack, so he had to silently make a note in his heart.

Despite this, the grain of the Jin State is still not enough to eat, but under the trade sanctions of the Ming State, they have no food from the south to supply, and the life of ordinary Jurchens is quite sad.

As a result, the call for grass valley began to surge among the people of Jinguo.
