After Zhao Liangdong led his army to besiege Xingjing, he did not immediately stop the attack, but set up camp at the foot of the mountain, cut down trees, pulled up a long wall outside the camp, and built siege equipment at the same time, obviously preparing for a long-term siege.

At the same time, outside Shengjing City, the supplies of the Xia army were continuously sent into the camp, replenishing the huge ammunition supply, Yue Le and Ao Bai stood on the city wall every day, watching the convoy enter the Xia army camp, and the eyes of both showed a look of despair.

They knew that the Mongol tribes had completely abandoned them, and they had also abandoned their allegiance to the imperial court, as evidenced by the normal maintenance of the Xia army's supply lines.

Since the supply line of the Xia army remains normal, they can only be prepared to hold on for a long time, the grain and grass reserves in Shengjing City are abundant, and they can hold out for at least three years, but because the city is far away from the Hunhe River, the water can only rely on the well water dug in the city.

The Xia army outside the city also realized this, Su Dingyuan proposed to use rocket artillery at the beginning, set fire to the houses in the city, and consume a lot of water resources of the Qing army, but Su Ci and Su Fu did not agree, they were worried about the Han people in the city, once the fire spread, it is not a pity for the city to die, but the Han people will definitely die in large numbers.

In the report to the imperial court, Su Dingyuan and the three of them directly stated that the Qing army was now trapped in the lonely city of Shengjing, and there was no need to storm it, and asked the emperor to agree to besiege Shengjing for a long time until the city ran out of ammunition and food, and Su Yan agreed to their request.

However, since it was a long-term siege, there was no need to let the three governor-level *** stay in the Shengjing camp together, so he drafted a decree after discussing with the cabinet to cancel Su Ci's position as the governor of Shanxi and Hebei provinces established during the war, and changed it to the governor of Liaodong, and ordered him to pacify, buy, and divide the Jurchen tribes in the northeast that submitted to the Qing court, and win over the imperial court.

And Su Fu, considering that his status as the governor of North Korea was useful for commanding the 20,000 officers and troops provided by North Korea, stayed on the front line as Su Dingyuan's lieutenant general.

In addition, considering the importance of the land of Liaodong, Su Yan decided to cancel the Liaodong Prefecture established by the Ming Dynasty, and instead set up the Liaohe Political Envoy Division (named after the Liaohe Plain), and the provincial capital was temporarily located in Liaoyang Mansion, and then moved to Shenyang after Shengjing was recovered.

……

On the other hand, as the Mongolian tribes settled in the Horqin steppe requested to return to the Xia Dynasty, the eastern part of Monan Mongolia was finally returned to the imperial court.

The four parts are the Ten Banners, which are called the Jelimu League because of the Jelimu Ula Alliance in the territory of Horqin.

The submission of the southern tribes frightened the Mongol tribes further north, fearing that one day the Han army would follow the example of Ming Chengzu and go deep into Mobei, so some of the Mongol tribes migrated and fled from here, either north to the Khalkha Mongols, or fled to the Western Regions, after they moved away, the vacated pastures were soon contested by the remaining tribes, and war broke out.

At this time, Han envoys from the south suddenly visited, and they brought the will of the emperor of the Central Plains: surrender or die.

In addition to the decree of the Emperor of the Central Plains, Li Laiheng, the governor of Xuanda, and Marquis Mabao of Anding also began to gather the Mongol tribes of the Yikezhao League, the Chahar League, the Zhaowuda League, and the Zhuosuotu League, intending to continue to expand northward.

In the face of a powerful threat from the south, the Mongol tribes naturally did not have the courage to resist, and they sent their sons or brothers to the south with Han envoys to submit to the Xia army.

Among them, the tribes who did not want to submit were relocated, and they fled north in a hurry, asking for submission to the Khalkha Mongols who occupied Mobei, and in their opinion, it was better to submit to the Khalkha Mongols, who were also Mongols, than to be dogs for the Han Chinese.

The pressure thus came to Khalkha Mongolia.

At this time, the Khalkha Mongols were not a unified khanate, and they were divided into four major tribes, the four and their leaders were Tushetu Khan Chahun Dorji, Chechen Khan Babu, Zasaktu Khan Norbu and the leader of the Saiyin Noyan tribe, Tenzin Lama, the first three of which had sent tribute to the Qing court since the third year of Chongde, and were now nominally subject to the Qing court.

Surrender is submission, and it is naturally impossible for them to go to war with the Han people for the sake of the Qing court, but

They were also unwilling to submit to the Han Chinese in this way, so the Tushetu Khan, the Chechen Khan, and the Zasaktu Khan began to send envoys to communicate with each other frequently.

The Saiyin Noyan tribe did not participate in this, and instead of accepting the Mongol tribes who had fled north, its leader took the initiative to send envoys to make friends with the Xia army, hoping to become a subordinate of the imperial court.

The choice of the Saiyin Noyan tribe caused the other three tribes to be immediately dissatisfied, and they believed that the Saiyin Noyan tribe had betrayed the Khalkha Mongols and intended to unite to attack each other.

At this time of tension, Lama Tenzin sent an envoy to the Khan's tent of the three tribes and invited the Khan kings of the three tribes to the Hangyi Hamar Mountain on the border of the Saiyin Noyan tribe and the Tushetu Khan tribe, saying that this meeting was related to the future fate of the entire Khalkha Mongolia, and hoped that the three khans would consider it carefully.

The other three Khans were all "young men" who had just succeeded to the throne for a short time, and they did not respond immediately after receiving this invitation, and they were all considering whether Lama Tenzin had other intentions to lure them to the meeting point to be killed.

However, after Tushetu Khan Chahun Dorji sent people to conduct a thorough search in the area of Hangyihamar Mountain and confirmed that there were no ambushes from the Saiyin Noyan tribe there, although he was puzzled, he was relieved and decided to accept the invitation of the Lama Tenzin under the persuasion of the nobles.

To be on the safe side, he led his army to camp around Mount Hangyihamar in advance, and after Chahun Dorji accepted the invitation, the other two Khans also relaxed and went there happily to see what this Tenzin Lama said about the future fate of the Khalkha Mongols.

In mid-April, the leaders of the four Khalkha tribes converged at Hangyihamar Mountain, and for safety reasons, they all brought enough Mongolian cavalry, so the neighing of war horses could be heard everywhere around Hangyihamar Mountain, which was extremely lively.

Chahun Dorji, who arrived here in advance, built a big tent at the foot of the mountain, because the mountain was located in the territory of the Tushetu Khan, he became a well-deserved host, sitting on the top position, the Tenzin Lama was the oldest of the four, sitting in the second position, and the Chechen Khan was the weakest, sitting at the end of the throne.

After the four of them sat down one after another, the three Khans all set their eyes on the Tenzin Lama, and Tushetu Khan had a bad face and said, "Normen Khan, the three of us were invited here by you to hear about your so-called future fate of the Khalkha Mongols, if what you say does not satisfy the three of us, then don't blame me for not remembering the old feelings."

The old love in his mouth refers to the relationship between the two, the Tenzin Lama is a descendant of the youngest son of Dayan Khan, the son of Gegasen Zazar, and the son of Gegasen Zazar, the eldest son is the ancestor of the Tushetu Khan tribe, and the third son is the father of the Tenzin Lama.

In the face of the naked threat from his juniors, Lama Tenzin smiled slightly, but he was not in a hurry, he reassured: "Chahu Dorji, don't worry, you have three troops together, the soldiers are strong and strong, and my Saiyin Nuoyan Department is naturally invincible, so why rush for a while? Listen to me slowly."
