The large ladder truck of the Qing army was destroyed, and another way was come up with: to cooperate with the attack of the city with Jinglan and Wanglou vehicles. Jinglan and Wanglou vehicles were higher than the Yangzhou city walls. Archers and firearms could shoot in the city from a high point above, while Jinglan and Wanglou vehicles could be outside the range of the defenders' rockets and were difficult to destroy.

However, Li Guodong had scattered soldiers, so the chariot was almost useless. The Qing soldiers who climbed up the chariot and shot arrows from a high place were all shot one by one by one by one by the scattered soldiers of the Huai Army.

The tall and strong well railing became the most troublesome weapon for the defenders in the city. The Qing army's turtle dove-legged gunner and light Folang machine gunner hid in the well railing. On the platform of the well railing was a completely closed building. The Qing soldiers extended the turtle dove-legged gun and Folang machine gun from the shooting hole, and shot the city from a high place, causing great losses to the defenders at the city.

However, the Qing army's well railing was finally destroyed by the Huai Army. The Huai Army concentrated the red cannons and bombarded a well railing with twenty cannons, and finally knocked the well railing to pieces.

If there were no cannons, in the era of pure cold weapons, we had to break the well railings by relying on counterattack forces to go out of the city, burn the well railings with rockets, or cavalry approached to throw tincture tanks and torches to burn the well railings. Now that there were cannons, the Qing army strictly guarded Li Guodong's cavalry, so the way to counterattack forces to go out of the city to destroy the well railings would cause heavy losses to one side. Li Guodong simply concentrated on bombardment of the cannons, and eventually destroyed all ten well railings built by the Qing army that had consumed a lot of manpower and material resources.

"We have been holding on for more than a month. The city wall was ragged by the Tartar cannons, and the officers and soldiers guarding the city suffered heavy losses. If the enemy was lured into the city at this time, Jiannu would not be suspicious again. From today on, we will retreat little by little and put Jiannu into the city." Li Guodong was preparing to arrange a plan to lead the enemy into the city and burn the Qing army.

"Duoduo is very tricky. I'm afraid he will enter the city and let the Green Camp go to the city to die first. I'm afraid that the Eight Banners soldiers will not enter the city." Wang Quandao.

"After Jiannu broke a gap, we asked the defenders on the city to retreat into the city street fighting and block the enemy. After a period of street fighting, we would find an opportunity to withdraw all the people and then cause fire. It is estimated that this fire would burn all the green camp. The cavalry left outside the city also waited for the opportunity to attack Jiannu's Han Eight Banners artillery positions. When the fire broke out in the city, all our infantry and cavalry came out and launched a fierce attack. In this way, Jiannu would be defeated." Li Guodong arranged a combat plan.

As for the Qing army's defeat, things were simple. The Huai army followed behind and chased the Qing army northwards. At the same time, Li Guodong also sent a secret letter to Huang Degong, asking Huang Degong to cross the Yangtze River, arrange defense lines from the Baxiantai to Zhimaling area, block the Qing army's retreat to the west, and force the Qing army to retreat northward and enter the lower reaches of Hongze Lake.

As long as Duoduo's defeated general enters the lower reaches of Hongze Lake, it will be easy. As long as the Gaojiayan bursts the dam, the Qing army will all become fish and turtles.

"What if Duoduo insisted on going west? Jiannu knew about Gaojiayan. If the Duke of the Kingdom attacked the water, Jiannu would be wiped out." Lu Zhenfei asked.

"Let him go west and you can ambush heavily along the way. Even if Duoduo can escape back, how many people can be left of his 600,000 army?" Li Guodong said with a smile.

If Duoduo came out of Yangzhou and went straight west, if he wanted to go to Anqing to meet with Ajige, there would be many hilly terrain on the way, as long as the Ming army used the terrain to block it step by step, even if the Qing army could rush through the Ming army's defense circle, there would be very few left to escape.

Yangzhou City blocked Duoduo for a month and a half. Although Ajige joined Zuo Menggeng's army and crossed the Yangtze River in Jiangxi, Ajige's situation was not very good. Ajige's middle army had a military fortress group centered on Wuchang to the west, and a rebel army that had been recruited by the Ming army was active in the north of the Huguang Jiangbei area. Li Chengdong, Li Jianshen and other Gao Jie troops were stationed in the east. If Duoduo was defeated, Ajige's middle Qing army would be in danger.

If the Qing army of Dodo and Ajige were completely over, Dorgon would not consider unifying the world, but how the Qing Dynasty would protect itself. At that time, Dorgon would have to be forced to transfer the Haoge army that was preparing to attack Sichuan back to the Central Plains to defend against the Ming army's northern expedition.

If Ajige was smart enough and found that the situation was not good, no matter how Duoduo ran away, he could still bring back 30,000 Manchu Eight Banners soldiers. In addition, Manchu Eight Banners who stayed in the capital and Manchu Eight Banners who followed Haoge and Wu Sangui's western expeditions, there would be 70,000 Manchu Eight Banners, which would enter the north-south confrontation, and the Ming army was temporarily unable to fight the northern expedition, and Haoge still had the opportunity to attack Sichuan and defeat Zhang Xianzhong.

Since Gaojiayan was in hand, the Qing army did not dare to attack Huai'an, so the canal still firmly control the Ming army.

In the battle of Yangzhou in original time and space, before the Qing army attacked Yangzhou, Huai'an and Gaoyou Lake had already fallen into the hands of the Qing army. The Qing army recruited a large number of canal boatmen for their own use and incorporated canal boats into the navy. Therefore, in the original time and space, the Qing army had the Qing army's Daqing navy, which was not inferior to the Ming navy. In addition, the contradiction between Shi Kefa and Hongguang regime, all the Ming navy crossed the river and headed south, and Yangzhou became an isolated city and surrounded by the Qing army.

However, in this time and space, the Qing army could not surround Yangzhou from all directions, and Li Guodong and others could evacuate from the water gate to the east and evacuate to the Grand Canal at any time.

The Tawau Castle that controls Gaojiayan is really important. With water as a soldier, it successfully defended dozens of cities including Huai'an, Gaoyou, Yancheng, Shanyang, Huaiyin, Andong, as well as the Grand Canal. Even if the Qing army had a large army of 600,000, they did not dare to step into the mine pool half a step.

Duoduo, who is familiar with "Romance of the Three Kingdoms", naturally knew that the flood areas after the Gaojiayan broke, the Qing army did not even dare to touch them.

If Li Guodong did not defend Yangzhou and directly opened the city gate and gave up Yangzhou, Duoduo would definitely suspect that Li Guodong would use fire to attack. Will Li Yan's plan to empty Jinan fail? Only a group of Green Camp soldiers were burned to death, and even a hair of the Eight Banners soldiers was not burned.

The Qing army attacked wildly day and night, and the defenders were really unable to bear it.

The Huai Army in the city has begun to prepare for fire attacks. Large yards are filled with firewood, and tiny oil tanks and gunpowder are buried underground. The fuse is placed in the bamboo tube and buried underground. The fire is located in the secret room of a house. When all the defenders retreat, they are fixed with an incense. When the incense burns to the fuse, the fuse will be lit, which will detonate the gunpowder buried underground everywhere, tiny the tiny oil tanks, causing a fire in the city.

Before the defenders retreated from Yangzhou, some people were left to fight with the Qing army for a while to confuse Duoduo and then evacuate from the water gate to the east.

The Qing army launched a more crazier attack, capturing a large number of people from the towns and villages they occupied, forcing the people to build various siege weapons. When the Qing army launched another fierce attack, they dispatched fifty well rails, two hundred ladder cars, fifty rushers, one hundred chariots and thousands of shield cars at one time!

After the arrested people built siege weapons, all the men were incorporated into the Green Camp auxiliary soldiers and launched a fierce attack on Yangzhou.

Li Guodong stood at the top of the city and saw that the Qing army was covered with darkness on the west side of the city, densely packed, endless, stretching to the horizon. There were countless siege weapons, spreading all over the mountains and fields, crushing towards Yangzhou City.

Among the Qing soldiers, there were many people wearing tattered civilian clothes. Those were the auxiliary soldiers of the Qing army newly formed into the Green Camp. Except for a few people who gave a number coat, the rest were still wearing the clothes of ordinary people. Behind the auxiliary soldiers and the Min Zhuang were the black Green Camp war soldiers, followed by the Mongolian Eight Banners archers and the Han Eight Banners firearm soldiers.
