As early as the end of June, the Ming army in front of Liaodong Town did not fight, and was ordered to take the initiative to evacuate Guangning City and Dalinghe City.

This made Huang Taiji's carefully laid out plan to encircle the reinforcements after returning from the victory completely failed.

Since this plan has failed, it is pointless for Huang Taiji to station a large army outside Quang Ninh City.

Now he already knew the city defense situation of Jinzhou City and Yizhou City, so he had no intention of attacking the Ningjin defense line for a while.

Therefore, after learning that the defenders in Guangning City abandoned the city and left, they first sent Ao Bai to follow Cao Wenyao's subordinates to submit a letter to negotiate peace outside Jinzhou City, and then sent Yue Tuo to lead the Red Flag Army to the north to Tieling and Kaiyuan to garrison on the first line, and handed over the northern gateway of Shenyang, the capital of the Later Jin Kingdom, to Yue Tuo, the lord of the Red Banner with Red Flag.

At the same time, for the Zhenglan Banner owner Mang Gurtai, who has always wanted to split up and work alone, especially the Zhenglan Banner owner Mang Gurtai, who has repeatedly proposed to leave the surrounding areas of Shenyang and garrison Tieling Kaiyuan, Huang Taiji did not let him get his wish, and divided Niu Lu under the Zhenglan Banner into three.

The largest of them, the Thirty Niu Lu, was led by Mang Gurtai and returned to Shenyang with Huang Taiji's Zhenghuang Banner army.

The other group, Twenty Niu Lu, led by Mang Gurtai's henchman and half-brother Ang Alla, was stationed in Quang Ninh City.

Mang Gurtai's mother, before being snatched up by the old slave Nurhachi and established as the Great Fu Jin, was also a tribal leader of the Great Fu Jin, and had already given birth to a son at that time, which was this Ang Alla.

It's just that when Nuer Hachi killed Ang Ala and snatched Ang Ala's mother as his own blessing, Ang Ala was still very young, so he not only left his life, but was also brought to Hetuara City by his mother, who was favored by Nuer Hachi at that time.

However, Nuer Hachi killed Aung Allah's biological father and then robbed his mother, and although Aung Alla was ignorant at the time, he still knew these old things when he grew up.

When Nuer Hachi was alive, he didn't dare to have any dissent, even if his mother was deposed and then killed because of his relationship with Daishan**, he didn't dare to stand up and say nothing.

But when Nur Hachi died, Aung Allah's revenge grew stronger.

Since he was not the son and nephew of Nuer Hachi, that is, he was not a descendant of the so-called Aixin Jueluo family, so after his mother's death, he could only rely on his half-brother Sanbeile Mang Gurtai for a living.

And Mang Gurtai also knows this, so since Huang Taiji snatched the Khan throne, Mang Gurtai, who was originally ashamed of Ang Ala, began to rely on Ang Gurtai in his blue flag, and the two were getting closer and closer.

In just a few years, Mang Gurtai placed Aung Alla in the position of the Blue Banner Meler.

This Angala, who is full of hatred for the Nuer Hachi family, also hit it off with the ambitious Mang Gurtai, constantly encouraging Mang Gurtai to oppose Huang Taiji and support Mang Gurtai to find another place to stand on his own.

Because of this, Mang Gurtai has great faith in his half-brother Aung Alla.

If it weren't for the descendants of Ang Alafi Aixin Jueluo, then Ang Alala, who was a few years older than Mang Gurtai, would have been the solid mountain of the Blue Banner a long time ago.

Of course, this solid mountain Ezhen of the Zhenglan Banner is not someone else, but another half-brother of Ang Alla and Mang Gurtai, that is, the tenth son of Nuer Hachi, Derge.

This Derge, although he is Mang Gurtai's younger brother, is not the same heart as Mang Gurtai, but is more inclined to Huang Taiji.

Just like the current Blue Flag Banner Lord Zilharang, he is obviously the younger brother of the same father and mother of Erbel Amin, but he turned his elbow outward, and he has been desperately supporting Huang Taiji, the murderer behind his father's death.

Of course, this is rewarded, such as Zilharang, who supported Huang Taiji, and now after Amin was imprisoned, he succeeded Amin as the owner of the blue flag.

And the Derge class was also young, and he squeezed out the half-brother Ang Alla and became the solid mountain Ezhen of the positive blue flag.

This time, Mang Gurtai, who was bent on going out to garrison, did not get his wish, and Dege, who was closer to Huang Taiji, led the other twenty Niu Lu with the Zhenglan Banner and was arranged to the most important gateway to the west of the Houjin Kingdom, and stationed in Dalinghe City, which was voluntarily abandoned by the Ming army.

Daling River City was built on the lower reaches of the Daling River, surrounded by a plain and open area, with no topographical barriers except for a Daling River that froze in winter.

The Ming army has built a city here for many years, but this city has changed hands many times between the Ming army and the Jianyu since the construction of the army, and there are no merchants and ordinary people for a long time, and now it is purely a military fortress.

Historically, the construction of Dalinghe City was to add a barrier to Jinzhou more than 100 miles behind, and it was also a symbol of the Ming army in Liaodong to show its enterprising spirit.

But after building Dalinghe City, the Ming army in Liaodong actually dug a hole for itself.

Because after winter, the Daling River freezes, and the Daling River City is in no danger to defend, and the Jianyu cavalry can gallop through.

Therefore, in order to ensure the safety of Dalinghe City, the Ming army of Liaodong had to build fortresses further east of Dalinghe.

A series of fortresses such as Qiantun, Youtun, Lingbei Fort, Panshan Fort, etc., all came from this.

Why did the Ming court continue to increase the salary, causing the people's resentment to boil and the people to riot?

It is because Liaodong Town has spent a lot of manpower, material and financial resources to build a series of military fortresses north of Jinzhou, especially on the east bank of the Daling River.

Of course, the construction of these fortresses cannot be said to be useless, because their existence is indeed a serious threat to the construction of the captives.

However, when you can't win a decisive battle in the field, you don't always want to provoke the enemy.

After all, you can't build all the way outside Shenyang just by building a fortress.

Needless to say, the results are true.

The Ming side has been building, and the Jianyu side has been destroyed.

However, it is very difficult to build, but it is very easy to destroy.

In the end, these fortresses not only did not play their due role, but also dragged down the finances of the Ming Dynasty.

Now, after the Chongzhen Emperor ascended the throne, although the financial problems were alleviated by raiding his home, he never ordered the renovation of the fortress north of Jinzhou.

Including this Dalinghe City, it is still basically the dilapidated appearance after it was occupied and destroyed by Jianyu in the summer of the seventh year of the Apocalypse.

Now, since Derge led the twenty Niu Lu of the Zhenglan Banner, that is, the army of 6,000 Jianlu, into Dalinghe City, the heavy burden of repairing the city and transporting supplies over long distances was also transferred to the head of Jianlu.

When the messenger sent by the minister Zheng Zhihui came to the outside of Dalinghe City not far away, the scene he saw was a lively scene of building the city in a hurry.

The Zhenglan Banner Gushan Ezhen Dege, who is also the title of Baylor, is now leading his subordinate Niu Lu and the clothed slaves accompanying the army to dig and ram earth to build the city in the dilapidated place of the city.

At the same time, it also rebuilt the houses and buildings in the city that were deliberately burned and destroyed before the retreat of the Ming army.

Cao Wenyao's troops in Quang Ninh City, when they got the news of the retreat, a large number of enemies were outside the city, and there was no time to destroy the city.

The defenders of Dalinghe City, Jin Guofeng, were different, they got the news early, and there was no enemy siege, since they abandoned the city and retreated, they naturally had to destroy everything that could be destroyed.

The outer city wall is not easy to destroy, it is the houses and buildings in the city, such as the granary, the official office, the barracks, the houses, shops, etc., all that can be taken away are taken away, and everything that cannot be taken away is destroyed.

When Zheng Zhihui's messenger shot out the letters he was carrying from afar, and Kuaima returned to Jinzhou, the news he brought back made He Kegang, Jin Guofeng, Zu Dale and others very happy.

Which of them, the front-line generals who have been fighting and stationed in Liaodong for more than ten or twenty years, does not know that destruction is easy and construction is difficult?

Who wouldn't know that building a city to the north or east of the Ningjin Line would do more harm than good?

Now that I saw that Jianyu's army, which was originally good at field warfare, was also stationed in the city, and began to repeat what the Liaodong Ming army had done for decades in vain, how could I not be happy?

For Jianyu to build a city, garrison troops, and then confront the Ming army, the generals of Liaodong Town were not worried at all.

Because since last year, more than 200 Shenwei invincible general cannons have been shipped to the front line in eastern Liaodong one after another, and the Yizhou City and Jinzhou City alone on the front line have a total of more than 100 guns.

With these Shenwei invincible general cannons that imitate the heavy Hongyi cannons, once the imperial court launches a counterattack, no matter what kind of city you build, it will not be able to stop the repeated bombardment of the Hongyi cannons.

Therefore, these generals guarding Jinzhou are not worried about the rebuilding of Dalinghe City by the Jianyu side.

After the Ming army simply withdrew its troops from Guangning City and Dalinghe City, they not only threw away a dangerous burden themselves, but also transferred this burden to Jianyu at once.

At the same time, the number of defenders in Jinzhou City also reached an unprecedented number of more than 17,000.

With more than 17,000 people, even if the city is besieged by 100,000 troops in the future, Jinzhou City will be enough to protect itself.
