Azig and Kong Youde, who had basically completed the task of destroying Korea, immediately took action after receiving the orders of their masters.

Azig's Eight Banners Army and the Mongolian Army are still the Chinese army, and the vanguard is still led by the "Marshal of the Capital" Kong Youde.

At the beginning of August, the traitor generals Geng Zhongming, Ma Guangyuan, Shi Tingzhu, Zu Zerun, Zhang Cunren and others drove the Goryeo servant army to launch an attack on the territory of Yiju, where Dongjiang Town was entrenched.

Mao Dashuai died unjustly, Dongjiang Town fell apart, and two years later, there was a Wuqiao Mutiny that affected half of Shandong, which was simply a disaster.

With the assistance of the "Red Banner Army", Dongjiang Town, which had just slowly recovered from the chaos, adopted the strategy of taoguang and obscurity in the past two years under the leadership of Huang Long and Jin Sheng.

Jiannu defeated Korea, and the Korean lord Li Liang repeatedly sent envoys to Donggang Town to ask for support, and even Korean civilian and military generals rushed out of the Jiannu defense area and traveled thousands of miles to Uiju to ask for help.

Shen Shikui, Mao Chenglu, Shang Keyi, Li Weiluan, Xiang Zuolin and other generals all knew that the Jin army would deal with Dongjiang Town after taking North Korea, but they were extremely disgusted with the Korean lords at both ends of the first rat, and they didn't think of helping them at all.

Huang Long and Jin Shengjian saw that their subordinates were not keen on helping North Korea at all, and of course they would not drive ducks to the shelves, so they chose to stick to Yiju to run Tuntian and dug a lot of trenches.

The good way of digging criss-crossing trenches to defend the soil is now understood by the generals of Dongjiang Town, because the effect of Dongping Hou digging trenches to encircle Jinzhou is obvious to all.

Trade with Dongjiang Town is the task of "sun and moon shipping", even if the profit is not high or even unprofitable.

At the end of last year, before the freezing of the port of Phi Dao, the merchant ships "Sun and Moon Shipping" carried 20,000 Shi Japanese milled rice, tea, cotton for mink, Korean ginseng, timber, Dongzhu and other goods under the escort of the Udvo and Venlo.

Huang Kezao and Shen Ming traveled back and forth to Dongjiang Town many times, and each time they would drink and talk to Huang Long and other major generals.

The generals of Dongjiang Town all knew that Huang Kezao and Shen Ming were the henchmen of the Marquis of Dongping, and they held real power in their hands, and they did not despise them at all because they were young and had a low official position.

Moreover, everyone in the Ming Dynasty knows that the average age of the generals of the "Red Banner Army" is in their twenties, and the average age of the regular soldiers is not more than 20 years old, and it is a new army full of vigor and vigor.

Huang Kezao was originally a scholar of Bai Yangcui, not only literate, but also read and listened to a lot of the Four Books and Five Classics, followed Huang Han for five or six years, and learned a lot of new knowledge.

Shen Ming was the best among the first four disciples of Huang Han, and he was also more confidant, and he realized that his mentor had great ambitions, and he would definitely be able to soar to 90,000 miles one day.

Huang Kezao and Shen Ming not only chatted with military generals such as Huang Long and Shang Keyi, but also with Jin Sheng and several other civil officials.

Drinking and chatting inevitably talked about the situation in North Korea, and Shen Ming and Huang Kezao seemed to inadvertently reveal that it was best to let Jiannu beat the Korean people to destroy the country and extinct the species.

In the future, the Dongjiang soldiers of the "Red Banner Army" may be able to conquer half of the former Korean territory, and even if they use the Han River to divide the river, it will be happier than occupying hundreds of thousands of acres of land in Uiju and making a small fuss.

Kim Sung-nai was a scholar who read poetry and books, and was familiar with the history of Goguryeo, Baekje, and Silla, and even more knew that Korea was a country that was not conquered by Taejo, and was one of the vassal states of the Ming Dynasty.

The "Red Banner Army" and Donggang Town have the strength to take over half of the territory of North Korea, but doing so will not only be unjustifiable, but will also be charged with trespassing on the border.

However, in the case of Korea being built and the country destroyed, it is a different matter.

The "Red Banner Army" and Dongjiang Town's conquest of Korea has become a war of Jiannu, and when the division is famous, it is entirely possible to ask for a high-profile entry into Korea to attack the Jin army to seize territory.

The Later Jin army was bloodied in Korea, and the population of this land had lost more than half, and the territory captured by the Jin army after the defeat of the Ming army naturally would not be returned to the Koreans.

At that time, it would be a good idea to exile all the captured exiles to North Korea.

Huang Han had a good idea of what his attitude was towards Jiannu's conquest of Korea, and he also knew that Dongjiang Town did not have the strength to start a big war, so he had to choose to advance and retreat with the friendly "Red Banner Army".

Huang Long and a military general did not have a good impression of the Korean monarchs and ministers, and everyone gloated when they saw that the Korean lord had fled to Juehua Island after the Jiannu had been beaten in the past few months.

Jin Sheng and the generals of Donggang Town were inexplicably excited when they learned that Huang Han coveted Korean territory, and they took the opportunity to harvest and store some grain as much as possible to cope with the complicated battle situation in the future.

During this period, Huang Long and Jin Sheng accepted some Korean civilian and military generals who refused to surrender to Jiannu and went into exile in Uiju or Phi Island, organized the defeated soldiers they brought with them to train, and established a Korean Volunteer Army.

At the same time, Uiju and Jingang Fort were actively preparing for war, preparing for the inevitable large-scale attack of Jiannu after the conquest of Korea.

In the past two years, Dongjiang Town has received a relatively large proportion of Liao's salary, and the number of people and horses approved by the imperial court has reached 23,000, plus the timber and mountain goods business is easy to do, and there are hundreds of thousands of stone wheat harvested in Yizhou Tuntian, and now there are 180,000 soldiers and civilians, of which Goryeo sticks have reached 40%.

Without exception, these Koreans were all ruined by Jiannu and the Houjin army and died in the world, and they had a deep blood feud with the Houjin army.

Many of them are North Korea's surviving civilian, military and aristocratic generals, who are supposed to be the country's elite, a group of national heroes who refuse to follow the crowd and choose to fight to the death.

Because the military and civilians of Dongjiang Town were psychologically prepared and also strengthened the construction of the defense line, the Later Jin Army did not go well to Yizhou in mid to late August of the seventh year of Chongzhen.

20,000 Donggang soldiers and 20,000 Korean volunteers fought against the Jiannu, Tartars, traitors, and Goryeo servants using the completed trench defense system.

Huang Long and Jin Sheng did not plan to fight together, nor were they blind enough to think that they could hold Uiju by themselves.

They had already received a letter from the Marquis of Dongping, and immediately retreated to the islands when they found out that the enemy was attacking on a large scale, and Huang Yong, who had received the news, had already led a huge fleet to the mouth of the Yalu River to meet the Dongjiang soldiers.

The small and medium-sized warships of the "Red Banner Army" water battalion that could enter the Yalu River did not sit on the mountain to watch the tiger fight, and they went up the river to shell the Houjin army that appeared in the firing range.

Although the casualties caused by the artillery on the warship were limited, the rumble of the cannon boosted the morale of the Dongjiang soldiers and the Korean volunteers, and seriously dampened the morale of the Houjin army.

The Dongjiang soldiers and the Korean volunteers did not retreat because they were hungry and scared a few years ago, and they were reluctant to give up when they saw that the four or five hundred thousand stone wheat that could be harvested had matured.

The 40,000 soldiers fought repeatedly with the Houjin army and the Goryeo servant army in the trenches, and the battlefield was filled with gunsmoke, and both sides actually fired at each other mainly with hot weapons and arquebuses.
