In the face of the people's war between the Korean army and the people and the pressure of the Liaonan Army of the Jingbei Army, Zilharang had no choice but to shrink his forces and rely on the fortified city of Pyongyang to hold on and wait for reinforcements.

In order to resist the Jingbei army and raise enough food, Jilharang even robbed all the villages and towns in Zhouzuo of Pyongyang in a frenzy, tied all the 60,000 Korean people in Pyongyang to the city wall, and used them as hostages.

The Joseon king, Yi Kuo, categorically rejected Zilharang's request, and his reply was, "Korea has been building a state for a long time!" Unless Zilharang chooses to go out of the city and surrender, he would rather have the blood of the people of Pyongyang run dry, and fight to the death to avenge the blood of the hundreds of thousands of Korean people who lost their lives twice indiscriminately. ”

With Li Liang's endorsement, Li Dingguo no longer had any scruples, so he passed on the letter to Zhang Wu, and led his headquarters to cross the Yalu River, attack Zhenjiang, Phoenix, Dangerous Mountain Fort, and Kuandian, and attack and advance to Hetuala, the old village of Dongyu, while he led the army and the Korean army in the direction of Seoul and Incheon, and attacked the Manchurian troops under the puppet Qing Zheng Prince Jierharang.

On 6 August, a coalition of more than 20,000 Jingbei troops and 30,000 Korean troops finally arrived outside Pyongyang.

In order to prevent the Manchurians from jumping over the wall in a hurry, the Korean people, who had been oppressed, even dug up the Taedong River in Pyongyang, completely turning Pyongyang's Zhouzuo into a Ze country.

In this way, it was impossible for the Manchurian soldiers inside the city to fight even if they wanted to fight the trapped beasts, and Zilharang watched the Chinese and North Korean coalition forces outside the city swaggering to build fortifications on the outskirts of Pyongyang.

Taking advantage of the fact that the soldiers of the Eight Banners were unable to leave the city due to flooding, they built three earthen walls two feet high and countless arrow towers and watchtowers on the outskirts of Pyongyang.

In the face of such a dilemma, Zilharang was helpless, he knew what the Ming people and Koreans outside the city wanted to do, but he was powerless to change at all, at this moment, he deeply regretted, regretted that he did not choose to fight to the death with the Ming army that invaded Korea, so that more than 15,000 Manchurian Eight Banners were trapped and died in the huge cage of Pyongyang.

The Eight Banners soldiers did not want to go out of the city and attack the Korean people who were building a defensive line, but the muddy road made it difficult for them to move an inch, and even if someone was lucky enough to rush to the defensive line outside the city, they would also be ruthlessly killed by the Chinese and North Korean coalition forces.

When it was useless to go out of the city and threaten the lives of the Korean people, Zilharang knew that he and his own Niulu had fallen into a desperate situation, and at this time he had to reconsider his future, that is, to lose his sincerity to the Sino-Korean coalition army, and in the face of survival and destruction, Prince Zheng of the Qing Dynasty chose the former.

"My prince said that as long as the Ming Dynasty accepts the surrender of our army, I am willing to release all the Korean people, lay down my arms, and be the most loyal servant of His Royal Highness King Yan for generations."

Outside the city of Pyongyang, in the line of Xining Gong and Liaonan Governor Li Dingguo, Gu Shantai, who was inlaid with the blue flag of the Qing Dynasty, knelt on the ground with a humble tone.

Gu Shantai is a native of Niumaozhai, and also one of the old people who followed the Nurhachi uprising, the battle of Sarhu, Gu Shantai personally led three hundred warriors to break the Ming State Jiliao Governor Yang Hao's flag, and then was favored by the old slave, and added it as the Zhenghuang Banner Jia Lazhangjing, and married the third daughter, which is a real Manchurian clan.

Gu Shantai, who has always regarded Ming and Koreans as pigs and dogs, had to wag his tail and beg for mercy in front of Li Dingguo and Li Liang for the life and death of Manchuria.

"Tell you the prince, only by releasing the people in the city, then we can consider accepting your request to surrender, otherwise there will be no need for peace talks, and accepting your surrender is a big matter, and His Royal Highness King Yan needs to decide."

Regarding Zilharang's request for surrender, Li Dingguo did not dare to be arbitrary, and there were corresponding prerequisites for not granting foreign military orders, and he could have a certain degree of autonomy at the military level, but at the political level, without the dictate of King Yan, Li Dingguo, the governor of southern Liaoning, would not dare to exceed his authority.

"This ......, please also ask Li Shuai to quickly go to His Royal Highness King Yan, there is not enough food and grass in Pyongyang City, and the minions are afraid that after a long time, King Zheng will not be able to suppress his soldiers."

Gu Shantai was angry and hateful, he didn't understand that the Qing Dynasty, which was still in full swing last year, would be reduced to the point of seeking satisfaction from the lowly Ming people in just one year, and he didn't expect that even if he laid down his arms and surrendered, he had to look at the faces of the Ming people.

"Li Shuai, the surrender of the Dongyu needs to be decided by King Yan, but now there are still 60,000 people in the city, you see, can our country exchange food for the people first?"

In the eyes of the king of Joseon, the population has always been more valuable than food, and there is a Mongolian cavalry in Li Dingguo's army, Li Liang believes that His Royal Highness the King of Yan will agree to Jierharang's request for surrender.

"You go back and tell Zilharang that the Korean state is willing to exchange grain for the people in the city first, tentatively five catties of rice for one person, if you and others do not approve of this matter, the commander will determine that you have no sincerity to surrender."

Li Dingguo thought about it for a while, but still agreed to Li Liang's request, anyway, he didn't waste a meter or a drop in the Northern Army, so there was no need for him to be this villain.

"Five catties of rice for one person, the slave will go back to the city to play to Prince Zheng, I think Prince Zheng will definitely agree to your king's request."

Gu Santai was overjoyed, even if the North Koreans were left as hostages, there was no need for so many people, because all the grain collected in North Korea before was transferred to Liaodong, the grain in Pyongyang City is now only more than 5,000 stones, and it is distributed to each Eight Banner soldiers, and a soldier only has about forty catties of grain, which is already the limit to support a month and a half, and now it is really a big advantage to be able to exchange the useless Korean people in the city for food.

Sure enough, after receiving Gu Santai's reply, Jilharang immediately agreed to the request of the Korean king Li Liang to exchange food for the population, and proposed that the Manchurians could send the people out of the city in batches, and hand over the people with one hand and the other in front of the defense line of the Sino-Korean coalition army.

In order to show his positive attitude towards the surrender, Zilharang quickly put into effect the demand for food and sent 5,000 people out of the city for the first time, and in order to show respect for Li Dingguo, the governor of Liaonan of the Ming Kingdom, the Manchurians did not even loot the personal belongings of the Koreans in the city.

Li Liang did not break his promise, after the population was counted, he ordered people to launch dozens of carts, handed over to the Manchurian blue flag Gushan Zhengu who went out of the city to transport the people, he also felt that this trade was a big advantage, five catties of rice can be exchanged for a North Korean, where can such a deal be found, not only to save the lives of the people, but also to enhance his reputation in the country.

When the news of the Manchu Korean garrison's request for surrender reached Ningyuan, Li Xingzhi only gave Li Dingguo one answer, when Manchuria broke Shenyang, did he let the people in the city go? When the garrison in the Dalenhe Fort forced by Manchuria ate people to spend their days, did they let go of the defenders in the city? Since they did not let go of the Ming people, why should the Ming people care about their life or death, they can take the Korean people out of the city and continue to surround Pyongyang.
