In the hollow castle, shooting holes were opened one by one, and three-pound cannons filled the shells, and the barrels were extended from the shooting holes, and the black holes were aimed at the underworld.

Above the solid Triangle Fort, a mortar cannon opened the cannon suit. The gunners filled the medicine room with gunpowder, then stuffed the flowering shells into the muzzle, and the fuse of the shells was exposed from the muzzle. As long as the fuse of the shells was ignited first and then the drug-guiding tube at the tail of the cannon will be fired.

"Prepare!" Zhang Shiwen shouted.

The personal soldiers around him shook the small flags and the artillery positions were ready to fire.

"General Zhang, wait!" A crisp voice of the girl came.

"Your Highness Princess!" Zhang Shiwen quickly turned around and saluted.

"General Zhang," Princess Kunxing frowned slightly and pointed at the refugees who were pushing the shield chariots under the city. "They are all innocent people and were captured by the thief army. We should find a way to save them, but the general wants to shoot the people. How can we bear it?"

"Your Highness Princess, if you don't fire the cannon and let Liu Ni attack the city, you will suffer your Majesty and Your Highness Princess! The last general will act on orders, and the order you receive is to protect Your Majesty and Your Highness Princess!"

"General Zhang, this city is so strong, can we use only muskets and bows without cannons? That can also kill fewer innocent people."

Zhang Shiwen replied firmly: "Your Highness Princess, even if we don't fire artillery, Liu Ni will attack the city with the people's ant attachment. At that time, innocent people will inevitably suffer casualties! Now fire artillery, destroy the shield cart, and prevent Liu Ni from expelling the people from getting close to the city wall. Perhaps less innocent people can be killed. If they are allowed to get closer, there will be more casualties and injuries to the people."

"Kunxing, you don't know how to fight. You can listen to General Zhang here. You can go down first." Chongzhen sighed. He felt very uncomfortable. His daughter was kind and kind, and he could not stand the death and injury of innocent people. However, after all, she was kept in a deep boudoir and had no idea about the current situation.

Zhang Shiwen was not a random killing of innocent people. He had saved many people. However, his lives were saved by Wang Quan, and he would sit whatever Wang Quan asked him to do. Wang Quan's life was also owned by Li Guodong. This time, the Huai army spent so much effort to rescue Chongzhen, in order to escort Chongzhen to the south and gather the loose Southern Ming, so that he would not be defeated by the Qing Dynasty as in real history.

Of course, Chongzhen didn't know these things, he only knew that these people were loyal and kind. In order to save himself and the Ming Dynasty, they defeated the pursuers and killed the generals all the way.

"Father..." Princess Kunxing turned her head and covered her face with tears.

"Fire the cannon!" Zhang Shiwen roared.

The gunners in the hollow ridge stretched out their torches and lit the cannons.

"Boom boom boom" Scarlet tongues of flames spewed out from the shooting holes of the castle, and white smoke rose from the castle. At the same time, the mortar above the solid triangle fort also made a dull explosion. Black shells rose into the air, and the fuse "wave" burned. The shells smashed into Liu Liangzuo's formation like meteors falling to the ground.

"Bang" A shield car was hit by a three-pound solid shell. The shell carried huge kinetic energy and smashed the shield in front of the shield car. The broken wooden bamboo strips knocked down more than a dozen refugees in the cart like shrapnel. The shells that remained unabated hit a commoner in the cart, and the man suddenly turned into a scattered blood and flesh foam.

Another three-pound shell hit a shield cart. The shell shot high and hit the top of the shield. Although it did not break the shield, it jumped up and flew behind the shield cart. It got into the crowd of Liu Liangzuo's soldiers who were escorting the formation. The shell hit Liu Nijun's dense formation, almost passing from the front to the back of the formation, and took away countless people's arms and thighs along the way, penetrated through the chests and heads of many people. After the Blood Hutong, there was a shrill scream.

All six hollow bastions in this military household can arrange three-pound cannons. In each hollow bastion, there are ten three-pound cannons. Because it is a hexagonal castle, there are three hollow bastions on each side that can exert firepower. Thirty three-pound cannons fired volleys, destroying more than ten shield cars.

The most powerful one was the bombardment of the twenty-four-pound mortars. Six Triangle Forts, each of which was equipped with eight twenty-four-pound mortars. Each side was covered with the firepower of twenty-four-pound mortars. The mortars fired from a high altitude, the shells fell into Liu Nijun's crowd and exploded. Some shells exploded after they landed on the ground. Liu Nijun's flesh and blood flew everywhere, and some shells exploded in mid-air, fragments and iron beads swept across, and a large area of ​​Liu Nijun was beaten into a hornet's nest and fell down.

Even the twelve 64-pound giant mortars and four thirty-two-pound red cannons on the top of the castle joined the shooting ranks. After one of the thirty-two-pound shells hit the first shield car, they tore all the shield carts and the refugees behind them into pieces. The shells bounced, passed over the head of the second shield car, and hit the third shield cart, smashing the third shield cart into pieces. Then the shells kept bounced and hitting the ground, piercing through the hundreds of feet long Liu Nijun formation, pulling out a flesh and blood alley.

The 32-pound shells as big as watermelon were extremely powerful. Those who were rubbed by the shells would fly everywhere. The shells crashed all the way, leaving behind bloody corpses, minced meat, internal organs and wounded soldiers wailing all over the ground.

The power of the sixty-four-pound mortar cannon is also terrifyingly powerful. The flowering shell fired by the mortar cannon is as big as a watermelon. The weight of the shell is 29 kilograms, which is nearly 49 kilograms (open kilograms). Such a large shell is filled with more than 20 kilograms of gunpowder, and more than 2,000 lead shells. There are also dark marks on the cast iron shell, which are found after casting from the mold. When the shell explodes, it first cracks from the dark marks, and the shell also explodes into hundreds of fragments.

Each 64-pound mortar shell can explode more than 2,000 sharp fragments and lead shells, and more than 2,000 bird guns fired volleys. After the explosion, a large area of ​​people was blown up. The bombs that fell to the ground exploded all the shields and overturned the car.

The three-pound cannon in the hollow ridge was fired at a rate of 500 meters, and the first round of shells was fired. However, in just twenty breaths, another round of shells flew out. The 24-pound cannon set up on the solid triangle cannon was not slow to fire because of the short gun barrel, and it was easy to load, and there was a fixed-load bag. After the gunners fired the shells, they immediately cleaned the cannon chamber and medicine room with a wet mop, wiped it clean with a dry mop, then stuffed the set-load bag into the medicine room, picked up the shell, put the fuse up, put it in the muzzle, and then completed the loading.

The 32-pound Red Cannon and the 64-pound mortar cannon are loading slowly, but because of the use of a fixed charge package, the shells can be fired again within 120 breaths, that is, within two minutes.

"Why is Li Zhe's cannon so powerful?" Ma Degong asked in horror as he looked at the formation that was bombarded by the cannon.

"They hid in the city and fired with red cannons and sky-storming cannons from a high place. The shells were simply giant cannons on the Red and Black Yi ships in Thailand!" Although Zhang Huanggai had never seen Western warships, he also knew something.

"How many casualties will we have to continue fighting like this?" Tian Xiong asked.

The artillery bombardment of the Huai Army defenders just now caused more than 1,000 casualties to the rebels, but fortunately most of the casualties were refugees, and the real rebels only lost more than 200 people. Such losses can still be afforded by Zhang Huanggai or Ma Degong.

But for the rebel soldiers, the continuous drop of artillery shells, flesh and blood flying everywhere, the ground was covered with minced meat, and the wounded were wailing. Such a tragic situation exceeded their psychological endurance. Because the artillery shells came from a high point, the cannon fodder that stood in front could not be used as a meat shield for them, and many artillery shells fell into the crowd of their companions, smashing them into pieces.

Not only the plundered refugees, but also the rebel soldiers were scared, and many people threw down their shields and turned around and ran away.

As a result, the rebel generals behind him immediately swung their swords forward and chopped them up, slashing the retreating refugees and soldiers into a pool of blood.

"Go up! Continue up! Those who retreat will be killed!"
