Xiketeng shot twenty arrows in a row, and the arrows were shot without any flaws. Each arrow was shot, and there was a rebel who either had an arrow in the throat or an arrow in the face. The arrows he shot were accurate and powerful. They shot the arrows in the face and shot directly through the skull. The arrows were killed when they were shot. The archery skills of more than a thousand Eight Banners prisoners were very accurate, suppressing thousands of rebels on the front of the city. In addition to the archers of the Zhongzheng Camp, the crossbowmen and musketeers of the Huai Army, suppressing the rebels on the front of the city did not dare to show up and shoot arrows.

Under the cover of the fierce firepower of the Huai Army and Zhongzhen Camp under the city, the auxiliary soldiers of the Huai Army threw sandbags into the moat, and the landfilled passages extended to the foot of the city wall at a speed visible to the naked eye.

At the end of the first round of attacks against the moat, the Huai Army dragged the shield cart and retreated to its own positions, preparing to load new sandbags and launch a second round of attacks against the moat.

The shield car group retreated, leaving only a small number of shield car used to protect the Wanglou car, and the rest retreated.

The scattered soldiers who stayed on the position fired a cold gun from time to time, making the rebel gunners dare not climb to the city to fight.

Seeing the shield chariot retreating, Li Guodong ordered: "Let the siege cannons fire, aim at the wall where the auxiliary soldiers filled the moat, and attack for a round of attack."

Two giant siege cannons that had been waiting for long were raised to their guns and aimed at the Ganzhou city wall in front. After receiving the order to open fire, Wang Quan ordered: "Fire!"

The gunner holding a torch walked up and aimed at the fire door at the tail of the gun. The drug tube "waves" burned, and it quickly shortened into the fire door. The gunner in charge of ignition ran away quickly, ran to the safe range and squatted on the ground, covering his ears with both hands.

The wall of this giant cannon is very thick, more than half a foot thick. The fuse in the drug cannon flashed with sparks, and it took about eight breaths before the launching drug bag was ignited.

"Boom" The super heavy siege cannon made a deafening roar, and the three and six feet long gun barrels trembled violently. The entire cannon stand shook heavily to the ground, and dust flew. A tongue of flames more than two feet long spit out of the gun mouth, and white smoke spread around it. A heavy sixty-four-pound cannonball flew towards the Ganzhou city wall with afterimage.

For the same cannon, the larger the caliber and longer the barrel, the higher the initial velocity of the cannon. The heavy shells and the high initial velocity will naturally increase.

The gun was shot very accurately, and the shells fell accurately on the city wall where the trench was filled. The heavy shells at high speed hit the city wall. A large section of the city wall shook violently like a strong earthquake. The bricks at the landing point of the shells were broken, and a large area of ​​rammed earth was exposed!

The heavy mortar also made a deafening roar, and the gun mouth spitted out a tongue of flames of more than ten feet long. A huge stone bullet weighing 500 kilograms rose into the air, drew an arc in the air, and smashed it towards the Ganzhou city wall.

A huge stone bomb fell from the sky, but the gun failed to hit the wall, landed in the city, and hit a house. Under the attack of the huge stone bomb, the house was crushed like an egg hit by a hammer. After the stone bomb smashed the house, it jumped up and hit a wall. The wall was shattered, and the shell hit a house. After smashing the house, the huge stone bomb rolled forward under the influence of the residual force, destroying more than ten houses in a row.

Cannons have high accuracy, but mortar cannons are difficult to master after all, and the gunners need to have a high operating level. In fact, the operation level of the Huai Army gunners is not bad, but it is just that a high-ballistic artillery like a mortar cannon is almost impossible to hit the first shot.

Li Guodong picked up the monocular telescope and looked towards the Ganzhou city wall. He saw that the city wall hit by the siege cannon, a large area of ​​bricks outside had been blown away, revealing the rammed earth inside. Li Guodong put down the telescope and turned to the soldiers around him and said, "The power is greater than originally planned. As long as there are more than a dozen shells, this section of the city wall will probably collapse."

Wang Quan said: "Master, you will have to get more than a dozen shots. If you hit two more guns, it will collapse."

Li Guodong smiled and said, "Can you guarantee that both guns in the back are shot in the same position?"

After the shield cart went back and filled the sandbags, it set off again, arranged the evacuated formation, and slowly pushed upwards towards the city wall again.

When the shield car group was pushed up again this time, it was much easier. The scattered soldiers on the Hokkaido were suppressing the rebel gunners in front of him, and there were archers, crossbowmen and musketeers under the city suppressing the long-range firepower of the defenders, so that the shield car could advance to the moat without any loss.

The auxiliary soldier who was pushing the cart picked up the sandbag and threw it into the moat. It didn't take long for this round to use up all the sandbags. Then the auxiliary soldier pulled the shield cart and retreated.

On the artillery position, the gunners of two giant cannons were busy. They had just finished cleaning the barrel. It was inconvenient to clean the barrel of this giant cannon, especially the cannon with a long tube, which required an extra-long mop to penetrate into the barrel and carefully clean it. Moreover, such a thick barrel was still a very troublesome to clean it.

Fortunately, this kind of giant cannon does not need to be injected and cooled, because it takes half an hour to clean and recharge, which is only one hour. If you cool down naturally for so long, you don’t need to inject water to cool down. After cleaning the barrel, the temperature of the cannon barrel has dropped.

The cleaning of the mortar cannon's chamber is relatively simple. With a thick and short gun barrel, everyone can get into it directly. The two gunmen took the wet mop and went deep into the medicine room. While cleaning the barrel, they also cooled the medicine room. Then they wiped the moisture with a dry mop and then loaded the shells.

When the shield car array retreated, two giant siege cannons had been loaded and launched another shelling.

"Boom" with a earth-shaking loud noise, the super-heavy siege cannon made another shocking roar, and a sixty-four-pound shell hit the Ganzhou city wall like lightning. The landing point of the shell this time was somewhat different from the last time, and the landing point of the shell was not very far from the last time. A large area of ​​bricks were peeled off again, revealing rammed earth.

Immediately afterwards, there was another dull loud bang, and the giant siege mortar cannon made a roar. The 500-pound giant stone bomb rose into the air, flew to the sky with powerful kinetic energy, and pulled out an arc, smashing it hard above the Ganzhou city wall.

This time the mortar was shot very accurately. The huge stone bullet fell from the sky and landed accurately on the city wall. The stone bullet hit the top of the city wall. Countless cracks appeared in the spherical large stones, the floor tiles at the top of the city wall shattered one after another, and a crack appeared on the ground. Under the huge impact force, the stone bullet bounced into the air again. When it flew up, it smashed a large section of the female wall behind the city wall. The stone bullet flew in the air for a while, landed on the ground, smashing a large area of ​​houses.

The shield car array once again advanced to the moat, filled a section of moat, and then retreated. Two giant siege cannons made a deafening roar again, smashing a large section of the city bricks outside the city wall, turning into a bare earthen city.

"Concentrate artillery fire and bombard rammed earth!" Li Guodong ordered.

The twelve-pound field guns, six-pound field guns, three-pound cannons, mortar cannons and other artillery fires one after another, and launched violent shellings on the city walls that were beaten by the siege cannons. The shells kept hitting the rammed earth layer that had lost the protection of the city bricks. Each shell hit, and the soil splashed, and the rammed earth layer gradually became thinner and shorter.

The shield chariot array, which had been loaded with sandbags, set off again. When the shield chariot array set off this time, the elite heavy armored infantry also set off, because this time it is possible to collapse the Ganzhou city wall. As long as the city wall collapses, the heavy armored infantry will enter through the blasting gap. In another direction of the Ganzhou city wall, the Huai Army has prepared simple cloud ladders and simple trench bridges. When the cannons blast the gap and the main force launches an attack from the gap, the ambush will launch an siege from the other side.
