The Qing army's move had a certain effect. The Qing army's auxiliary soldiers, Min Zhuang and Green Camp soldiers acted as cannon fodders, rushed to the moat and attracted the Ming army to attack them. The Han Eight Banners Wu Zhenchao Ha camp behind bombarded the city with red barbarian cannons, causing considerable casualties to the Ming army. When the auxiliary soldiers in front filled the moat, Min Zhuang was bombarded with red barbarian cannons behind. Many shells fell into the Qing army's own crowds, accidentally injured many Qing soldiers. However, Duoduo would not feel sorry for the loss of those cannon fodders.

The crossbowmen and bird gunners in the Huai Army suffered a lot of casualties. Although most of the crossbowmen and bird gunners were new recruits, the number of defenders in the city was far less than that in the Qing army, and it was obviously an unwise choice to compete and consume.

"If Jiannu comes to fill the moat again, he will only shoot with the defenders in the enemy stage, so that his brothers will not stand on the top of the city and get shells." Li Guodong ordered.

"Duke of Chu, are we just watching Jiannu fill the moat?" Lu Zhenfei asked.

Li Guodong shook his head: "Director Lu, don't you watch them fill the moat and ask your brothers to try not to get Jiannu's cannon on the top of the city? Can there be still a fortress on the enemy platform still shoot? In the past few days, let's prepare more sandbags to transport them into the city, and make plans after the sandbags are piled up."

"There are few defenders in the Fortress of the Enemy Platform, and I'm afraid it will not be possible to stop Jiannu from filling the river."

"Then let him fill it. If they cross the moat, don't they still have to attack the city? At that time, we will be on the top of the city. Gray bottles, ten thousand enemies, turbulent oil tanks, and rolling wood and stones can kill the enemy, and they can kill fake slaves in large quantities, and our army's losses will be reduced a lot. Lu Governor, I have few soldiers in my guardians, so we should not fight against Jiannu."

The Qing army launched an attack again. This time, the Huai army no longer allowed the defenders to counterattack. They only used soldiers in the enemy platform fortress to shoot the Qing army beside the moat through the shooting hole. After all, the garrison in the enemy platform was limited and could not stop the Qing army from filling the moat. They could only watch the water surface width of the moat shortened and approached the Yangzhou city wall.

Of course, if you think Li Guodong didn't have a backup plan, you would be wrong. The Huai Army infantry guarding the city piled sandbags onto the top of the city, and the crossbowmen and gunmen hid behind the sandbags and shot under the city. At the same time, the light cavalry and dracosmen who were active outside the city fought several counterattacks in succession, killing more than a thousand green camp soldiers, more than two thousand auxiliary soldiers and more than a thousand civilians, and destroying more than two hundred shield cars.

After nightfall, Li Guodong ordered the Minzhuang who was guarding the city to hang his baskets out of the city, repair the city walls that were damaged by the red cannons of the Qing army, and fill the damaged areas of the city bricks with new bricks. By dawn, the damaged city walls will be repaired. And after nightfall, there are still many actions to do, such as sending people out of the city to destroy the embankments of the moat and canals that the Qing army had finally piled up and cut off the canals, put the water from the canal into the moat, and destroy the landfill of the Qing army; at night, scattered soldiers approached the Qing army's camp, fired cold guns and killed the sentinels, and ran away after the battle.

After dawn, Duoduo saw that the achievements of the siege battle over the last few days were in vain again, and was furious: "I am passing on the order of the king! Continuous siege of the city regardless of day or night!"

On that day, the Qing army's offensive became even more crazy. Various cannon fodders were placed in front and killed. The archers behind the formation pressed the formation. The red cannons in the back formation aimed at the top of the city wall, and the bombardment was hit hard without distinction. The near-lost bullet fell into the Qing army crowd, causing considerable losses. The defenders at the top of the city wall eased the power of the red cannons with sandbags, hid behind the sandbags and shot, killing the moat filled with Qing soldiers' bodies.

The artillery battery at the top of the city also launched artillery positions from afar, but the smoothbore cannon in this era was very poor in its accuracy and the artillery battle effect was not ideal. Finally, Li Guodong ordered to concentrate twenty to thirty artillery guns to bombard a fiercely at one of the artillery positions of the Qing army, and to destroy a red cannon of the Qing army with about two to three rounds of fire.

After a whole day of offensive and defensive battle, the Qing army suffered heavy losses, with more than 5,000 corpses left under the city. The red cannons of Wuzhenchao Ha camp in the back formation were also destroyed by the Huai Army.

After nightfall, bonfires were lit under the city wall, and countless torches were inserted into the battlements of the city walls, and the two sides fought at night.

Night siege, for the defense, it is impossible to see the target clearly, and cannot attack the Qing army artillery, archers and firearms in the distance, and can only attack the targets under the city; while the Qing army can attack the city wall, so night battles are not good for the defenders. The Qing army siege overnight also made the Huai army unable to repair the city wall, and could only watch the city bricks be smashed one by one. Moreover, on a moonless night, Li Guodong's cavalry arranged outside the city could not play a role.

The cavalry of the Huai Army were all veterans brought back by Li Guodong from the outside of the Great Wall. Everyone has experienced many battles and has good food on weekdays. They pay special attention to eating fish, shrimp, carrots and other foods that can improve their vision. The soldiers have no night blindness, but the war horses cannot move on the night without moonlight. Only by firing a torch can they march.

But the cavalry fired a torch and was exposed.

Li Guodong came up with a way to counterattack at night: he ordered the light cavalry to carry horses and wrap their hooves without turrets. The man led the war horses to approach the Qing army, who was sieging the city. When he saw the torches and bonfires of the Qing army, he suddenly rode the war horses and launched an attack on the Qing army.

This move was very effective. When the Qing army, who was sieging the city fiercely, found that the Ming light cavalry was attacking, it was too late to form a formation to fight. As a result, Cao Bianjiao charged and killed countless people, burned down a large number of siege equipment.

The light cavalry, who had won a great victory, lit torches and evacuated to the canal on horseback. When the Qing cavalry arrived, Cao Bianjiao and the others had already boarded the transport ship.

In order to deal with the sneak attacks of the Ming army's light cavalry, Duoduo ordered scouts and cavalry to be scattered everywhere at night. As a result, under the various attack methods of Ming army's naval marines, scattered soldiers and night-descendant, the scouts and cavalry sent by Duoduo suffered heavy losses in the night battle.

In desperation, Duoduo could only rely on his advantage of having many soldiers and widespread generals to arrange a large number of spearmen, knives, archers and firearms to protect the two wings of the Green Camp Army, which made the Ming army's light cavalry dare not come again, but in this way, the troops siege were dispersed.

The Qing army attacked the city day and night, and the Yangzhou defenders fought to the death. The Qing army paved the way with corpses, and lost a large number of Green Camp soldiers, auxiliary soldiers and civilians. After nearly a month of fierce fighting, the Qing army finally filled several sections of moats and extended the battlefield to the bottom of Yangzhou.

After the battlefield extended to the foot of the city wall, the offensive and defensive battle became more intense.

The defenders at the city wall used lime bottles, and ten thousand enemies attacked the Qing army under the city. Each round of lime bottles and ten thousand enemies fell, exploded under the city wall, and boiling hot quicklime splattered everywhere. Countless Qing soldiers covered their eyes and fell at the foot of the city wall; ten thousand enemies were thrown from the city wall and exploded among the Qing army crowd, and the caltrops flew everywhere at the foot of the Qing army, killing the Qing soldiers.

The killing range of most of the 10,000 enemies was mainly at the feet. The elite troops of the Qing soldiers of the Green Camp were covered with armor outside the suit, and there was no defense on their legs. As a result, they were blown up by the 10,000 enemies, and countless Qing soldiers fell down immediately. Most of the fallen Qing soldiers were blown up, and dense caltrops and fragments were pierced into their legs. Such injuries were incurable in this era, and they could only be saved unless Li Guodong dealt with them.

Needless to mention the enemy of thousands of people, Qing soldiers who were fryed by lime bottles, sprayed quicklime into their eyes, and could only be washed with vegetable oil, soybean oil, or peanut oil, or their eyes would be blind. But Duoduo could not use precious vegetable oil to save those green camp soldiers.

Due to Li Guodong's butterfly effect, there have been soybean oil in this era that is cheaper than vegetable oil and peanut oil. However, no matter how cheap the soybean oil is, it is worth more than the life of the Green Camp soldiers in Duoduo's eyes.

"Master, Jiannu's large siege car is coming!" Wang Quan shouted.
