In March, the spring is still cold and the wind is biting, but the river between the hills has thawed, and the sound of rushing water can be faintly heard on the dry grass not far from the river. Pen, fun, and www.biquge.info

Chen Renxi, the imperial historian of the Liaodong Town Supervision Army, took the Guangning guerrilla Cao Wenzhao recommended to him by He Kegang, the deputy chief soldier of Jinzhou, and his six hundred cavalry, as well as the two Ningyuan warriors Wang Zhenyuan and Chen Guowei, who were newly recruited under his command, a group of six or seven hundred people, all riding fast horses to the southwest.

The river where the sound of water comes from in the distance is the Daling River that winds all the way to the east and finally flows into the Bohai Sea.

Since Chen Renxi supervised the army in Liaodong Town, the two secret folds and petitions, both of which have been approved by the emperor. First, 18 people, including the eunuchs of the Liaodong Town Supervisor Army and the official Ji Yong in the camp, were arrested and imprisoned, and then they all beheaded their homes with a secret request, and the entire Liaodong Town was suppressed with this single hand. When the eunuch Ji Yong of the prison army won the great victory of Ningyuan in Mangui and Yuan Chonghuan, he also stuck to Ningyuan City, which is not without merit, but now it is the consensus of the court to punish the remnants of the eunuch party, and Ji Yong and other eunuchs also played a dishonorable role in driving away Yuan Chonghuan, so they are very unpopular in the Liaodong Army.

Chen Renxi, as the new superintendent of the imperial history, if he wants to quickly gain the hearts of the army and establish prestige, the best way is to ask for an order to get rid of Ji Yong and other eunuchs. If it was placed in the past, it might be very troublesome to operate, but now, it only needs to be unknowingly sent a secret invitation to the emperor, and then after getting the secret decree, it can be carried out.

In addition to the Jinyi guards brought with him, Chen Renxi had no private person, he was completely a gun into Ningyuan, and then within half a month, he got rid of the most powerful lieutenant in Ningyuan City and even Liaodong Town with lightning speed, not only established prestige in the army, but also in Jinzhou and Ningyuan The people are also rumored to be miraculous, and many people of insight have come to vote, and Ningyuan Wujin Wang Zhenyuan and Chen Guowei are two of the very outstanding talents.

Historically, Wang Zhenyuan and Chen Guowei, the two martial artists, defected to Chen Renxi in March of the second year of Chongzhen, and Chen Renxi was ordered to patrol all sides of Liaodong at that time, because Chen Renxi was a flower explorer during the Apocalypse, Wang Zhenyuan, Chen Guowei and other Ningyuan celebrities came to visit. Among them, Wang Zhenyuan and Chen Guowei then took the opportunity to visit, and reported to Chen Renxi the news that the Karaqin Department of Eastern Mongolia had defected to Houjin.

The Karaqin Department was just outside the border wall northwest of Ningyuan City, and once Karaqin surrendered to Houjin, it would not only pose a threat to Ningyuan's left flank, but most importantly, it would directly pose a threat to the Ming Dynasty's Jingshi defense circle.

Because the Karaqin Department is located directly north of Jizhou Town and Xuanfu Town, if the Houjin army passes directly on the territory of the Karaqin Department, it can bypass Jinzhou, Ningyuan, Shanhaiguan, these heavily fortified cities, if the Houjin unites with the Eastern Mongolian tribes, especially Karaqin, breaks through the border and directly attacks the Beijing Division, the consequences are unimaginable.

Wang Zhenyuan and Chen Guowei told Chen Renxi about this situation, and at the same time suggested that Chen Renxi strike first, take advantage of the stability of the Jinzhou front, send troops to Karaqin, destroy the Karaqin Taijibulhatu who took refuge in Houjin, and then change a pro-Ming tribal leader.

After carefully analyzing the stakes and disadvantages, Chen Renxi agreed with the two of them very much, and then quickly reported it to Yuan Chonghuan, the governor of Jiliao at that time. It is a pity that the suggestions of Chen Renxi and others have not been taken seriously by Yuan Chonghuan. And Chen Renxi was a civilian official, and there were no soldiers in his hands, so the matter was finally settled.

Yuan Chonghuan did not pay much attention to the Eastern Mongolian tribes on the periphery of western Liaoning, and gave money and food rewards every year, even if he knew that Naiman, Ao Han, Zalut and others had hooked up with the Later Jin, he was still unwilling to give up the efforts to unite the Eastern Mongolian tribes to resist the Later Jin.

As a result, in October of the second year of Chongzhen, Huang Taiji led the Houjin army to the banks of the Narit River, which is now the upper reaches of the Xiliao River, and successfully allied with the Eastern Mongolian tribes.

As early as the beginning of the seventh year of the Apocalypse, the Bahrain, Zalut, Aohan, Naiman and other tribes of Eastern Mongolia, under the recommendation of the Horqin Ministry, had already accepted the reward and woo of the Houjin Khan Huang Taiji, and secretly took refuge in the Houjin.

It can be said that in the history of the Ming Dynasty and the Manchu Qing Dynasty, the seven years of the Apocalypse were a very important year. In the first month of this year, Huang Taiji inherited Nurhachi's Houjin Khan throne, and then went east to Korea, fighting from January to March, not only conquering Korea, but also plundering a large amount of gold, silver, grain and grass materials. After withdrawing his troops from Korea in March, Huang Taiji marched westward again, attacking Jinzhou and Ningyuan, and fought from April to June, this time, of course, he kicked the steel plate, suffered huge losses, and was defeated back to Shenyang.

However, Yuan Chonghuan, who had just achieved a great victory in Ningjin, was dissatisfied with the suppression of Wei Zhongxian and his party in the process of rewarding meritorious deeds, and resigned angrily. In this way, under Yuan Chonghuan's willfulness, Daming lost another opportunity to pursue and expand the results of the battle.

In August, the Emperor of the Apocalypse finally died of illness, and the Ming court in Beijing fell into turmoil from then on, and no one cared about what happened in Liaodong.

However, Huang Taiji was not idle when he returned to Shenyang, because he was worried that the defeat in Ningjin might lead to the instability of his khan position and was in urgent need of another victory, he set his sights on Lin Dan Khan, the co-ruler of the Eastern Mongolian tribes.

Lin Dan Khan was the leader of the Han tribe. The so-called Han Department is the Chahar Department, which is the orthodox lineage of the Northern Yuan Dynasty and belongs to the purest descendants of Genghis Khan's golden family. Because of this, Lin Dan Khan has always regarded himself as the Great Khan of the Mongols, and he is very unruly. Because he had to be on an equal footing with the emperor of the Ming Dynasty, the Ming Dynasty did not want to see him, and when he first ascended the throne, Lin Dan Khan wrote a provocative congratulatory letter to Huang Taiji, raising his head that "the Mongolian lord Baturu Qinghis Khan, who commanded 400,000 troops, asked the 30,000 people on the waterfront to be safe and sound", calling himself "the Mongolian lord who commanded 400,000 troops", and called him "the 30,000 big gold lord on the waterfront", the content is not allowed to develop in the west and hook up with the Eastern Mongolian tribes, otherwise the Ming Dynasty will be united to destroy the Houjin.

Lin Dan Khan's arrogance not only offended the Ming Dynasty and the Houjin, but also offended the Taiji of most tribes in Eastern Mongolia. Although Chahar is relatively powerful among the Eastern Mongolian tribes, about 100,000 people, but in the entire Mongolian steppe, he is not the strongest at all, so the Mongolian tribes Taiji, who has always been a bully, do not respect him very much and are unwilling to obey his orders, but the more dissatisfied the Eastern Mongolian tribes are with him, the more tyrannical Lin Dan Khan becomes, especially against the Horqin tribes who have taken refuge in Houjin, they have launched attacks again and again.

Finally, the Horqin tribes, which could not bear it anymore, united with the Naiman, Bahrain, Aohan, Tumut and other departments around the Xilamulun River Basin, and became the traitors and leading the way together. In September of the seventh year of the Apocalypse, the Later Jin Khan Huangtaiji sent Bel Azig to lead the Later Jin army, together with Logan Khan of the Tumut Department of Northern Liao, under the guidance of Korqin and other departments, and suddenly attacked the Chahar Department.

As a result, Lin Dan Khan, who was strong in the outside and in the middle, was defeated and fled westward, and Azig led Korqin, Tumut, etc., and the Manchurian and Mongolian coalition forces, followed the pursuit all the way, killing more than 40,000 people in the Chahar department. The forces of the Chahar tribe Lin Dan Khan have since completely withdrawn from the Xilamulun River Valley.

Since then, the Eastern Mongolian tribes in the Xilamulun River Basin have lost their co-owners, and the original ones who belonged to Lin Dan Khan, the Uzhumuqin Department and the Abaga Department, betrayed Lin Dan Khan and fled to Mobei to join Khalkha, and the Houjin forces then infiltrated into the Eastern Mongolia region, and the barriers outside the Great Wall in the north of the Ming Dynasty were lost.

After that, he took refuge in the Ao Han tribe of Houjin, and in order to be rewarded for his meritorious service, he began to help Houjin win over and persuade the Karaqin Mongol tribes to surrender.

The Karaqin Department, which had lost its backer Lin Dan Khan, was looking for a new backer, so under the central contact of the Ao Han Ministry, he began to hook up with Houjin. And Huang Taiji also has this intention. The original intention of occupying the Xilamulun River valley was only to win a battle, consolidate his position, and prevent Lin Dan Khan's power from continuing to expand eastward.

When he attacked Ningyuan in June of the seventh year of the Apocalypse, he gradually understood that the Liaoxi defense line from Jinzhou to Ningyuan and then to Shanhaiguan was really solid and not easy to break, so when he waited until October of the seventh year of the Apocalypse, after Houjin defeated and drove Lin Dan Khan, the idea of detouring to Mongolia to attack the Ming began to arise in his heart.
