As soon as Li Zicheng and others retreated from the earth platform, Guanning Army's artillery shells roared and hit the earth platform that was one or three feet high and more than twenty meters in radius, and a burst of earth bumps splashed.

Almost all dozens of shells flew from the top of Shanhaiguan City were hit on the earth platform, making the earth platform bumpy. After all, this is a large target with a radius of more than 20 meters. Although the accuracy of the cannons in this era is not high, it is still no problem to hit such a large target.

However, although the Guanning Army's artillery bombardment was fierce, it did not pose any threat to the two sky-rushing cannons hidden behind the earth platform. The Red Barbarian cannons wanted to collapse the large earth-rushing platform with a length of more than 20 meters each? Bang slowly. It was probably the same for a month, but the two sky-rushing cannons hidden behind the earth platform could beat Xiluo City in about ten days by using the method of fighting cattle across the mountains!

Wang Xin, who was hiding behind the large earth platform, took out the wet mop to clean the cannon chamber, took out the mop that had been dried by high temperature and put it in the bucket to wet it, and then put the mop into the cannon chamber to cool down. Then the apprentices pushed the cannon forward and reset it. After resetting, they put the fixed-loaded launching medicine bag into the cannon chamber to firmly use the pushing rod, then put a wooden board to compact it with the pushing rod, and then stuffed the shell into the muzzle, push the shell to the bottom with the pushing rod, and then stabbed the fire door with a pointed cone and stuffed a medicine twist.

About two minutes later, two sky-storming cannons roared again, and the shells rose into the air and accurately hit the top of Xiluo City.

Wu Sangui, who was standing at the top of the city, heard two cannons again. Seeing two more shells flying high above the ground platform and smashing them hard at the top of his city, Wu Sangui was completely shocked: the thief's giant cannon has a speed of fire! Before the red barbarian cannon was loaded, the thief's giant cannon actually opened fire again!

The advantages of short-barrel guns are that they dissipate quickly, load quickly, and can fire flowering shells, with a longer range; the biggest disadvantage is that they are not easy to aim at the target, and require experienced gunners to operate. However, this disadvantage is that they are not a problem for Zhao Peng. He can skillfully use the sky-storm cannon to accurately hit targets four miles away, with an error of less than three meters.

Two 64-pound heavy shells hit the city accurately, causing bricks and stones to splash. A large piece of the marble was knocked out, and a huge hole appeared in the female wall.

The Guanning Army infantry guarding the city no longer dared to stand behind the female wall, so they could only dodge far away, but many people were still hit by the brick fragments aroused by giant shells and fell down screaming. The Guanning Army gunners on the cannon were still nervously loading the red cannon. You must know that the loading of such cannons is very complicated. After firing the cannon, they need to pour cold water into the cannon chamber to cool down, then stand up the tail of the cannon, pour out the water in the cannon chamber, and then use a mop to wipe the chamber before they can start loading gunpowder. After filling the gunpowder, they will inject wooden boards, load the cannon shells, and then reset the cannon. The full set of procedures will take six to ten minutes.

The Guanning Army gunners were busy loading the Red Barbarian cannons, but they had just loaded gunpowder and had not had time to load the shells. The Shun Army cannons on the opposite side made another roar.

One of the shells fired this time fell less than one foot away from an 18-pound red artillery cannon. The heavy shells fell on the city bricks. The broken bricks splashed like shrapnel. The busy Guanning Army gunner screamed and fell down. After the shells landed on the ground, they bounced up and flew towards the direction of the red artillery cannon. Several Guanning Army gunners who had no time to dodge were penetrated by the shells. The shells hit the upper body of the first gunner, directly smashing his upper body into pieces, leaving only two legs standing on the ground; then they hit the waist of the second gunner, breaking them into two pieces; the shells brushed through the arm of the third man, and the whole arm disappeared.

The shells that had not yet subsided in strength hit the Red Cannon's cannon mount, and the entire wooden cannon was immediately crushed to pieces, and the broken wood pieces flew everywhere. The Red Cannon, which had lost its support, tilted to one side and rolled to the ground.

"Well, I directly destroyed a cannon from Guanning Army!" Zhao Peng, who was standing on the watchtower, saw all this from the Qianli Mile Mile Mile and screamed excitedly.

As the ace, the flowering bullet has not been used yet. The two sky-storming cannons have already destroyed a red cannon of the Guanning Army. If we continue to fight like this, it is estimated that from morning to evening, the red cannons of the Guanning Army will almost be destroyed.

Zhao Peng turned his head and shouted at Wang Xin under the looking building: "Change the flower bullet!"

"No!" Wang Xin responded.

The apprentices who served as gunners nervously used wet mops to clean the barrel. After cooling down, they pushed the gun to reset, then loaded the fixed-loading medicine bag, opened a box, took out a flowering shell from it, aimed the end with the cork bolt at the muzzle, and pointed the end with the cork tube fuse to the outside, stuffed the shell in, and then gently pushed the shell to the bottom with the push rod.

Because there is a cork bullet holder, there is no need to install a wooden board to seal it after the gunpowder is loaded. You just need to load the shell directly. After the shell is pushed to the end, the cork bullet holder can naturally seal the barrel.

Each flowering shell was filled with fifteen kilograms of new gunpowder and more than five hundred iron beads were poured into. The 25 kilograms of bullet body was cast of pig iron. Once it exploded, the hard and brittle pig iron shell would break into countless sharp fragments. In addition, more than five hundred iron beads filled in the shell could form countless fragments and kill the target on a large scale.

An apprentice stabbed the fire door with a pointed cone, pierced the medicine bag, and then inserted the medicine twist into the fire door to prepare for launch.

Just here, only a sound of cannons sounded at the head of Xiluo City opposite. Guanning Army's red cannons were finally loaded and a second round of shells was fired. However, because of the cover of the earth platform, Guanning Army's shells did not pose any threat to this side. All shells were hit on the earth platform, and no shell could land on the sky-storm cannon position.

Wang Xin and his apprentices can load and launch calmly without worrying about being retaliated against by the Guanning Army. Of course, this sense of security is based on the advantages of the Shun Army and the Guanning Army's field battle. If the Shun Army is not as good as the Guanning Army, Zhao Peng's sky-storming artillery position will be attacked by the Guanning Army. However, there is no need to worry about these problems at present. The Guanning Army is not as powerful as imagined. The most elite Guanning Iron Cavalry is just the servants of the Guanning Army generals. All Guanning Army staff only have a few thousand people. In addition to the strong artillery, the remaining Guanning Army's quality is not much better than the ordinary Ming army's combat soldiers in the Guanning Army.

Since the Ming Dynasty's civil union, the imperial group suffered heavy losses, and the civil union group took the opportunity to control the military power. From then on, the situation of civil union and military inferiority was completely formed, and the combat effectiveness of the Ming army quickly declined.

The military households established in the early Ming Dynasty were completely destroyed, and the military households completely degenerated into peasants; because the military households were already decayed and ignored the use, the Ming Dynasty had to adopt the recruitment system. When wars occurred, the recruited soldiers were used to go to the battlefield, while the original military households could only be used as auxiliary soldiers. However, because later civil servants deducted military pay, the officers could only eat empty salary, and the recruited soldiers quickly became rotten, so a strange system of servants emerged. The officers used the deduction of military pay and the greedy silver to raise a group of servants, and gave them enough military pay, the best food, and the best weapons and equipment.

Generally speaking, an army of 10,000 people would eat at least half of the empty salary, which means only 5,000 people. Most of these 5,000 people were cannon fodder, and only dozens of servants who could really fight were the main generals.

The reason why Wu Sangui's army was the most capable of fighting among the Ming army at that time was because Wu Sangui had more than 3,000 servants, so he became the most capable Ming army at that time. Except for these more than 3,000 Guanning Iron Cavalry, the other Guanning Army were vulnerable and were about to collapse. Because of this, Wu Sangui did not dare to fight with Li Zicheng in the field. Even though he was huddled in Shanhaiguan, he was still afraid that he could not defend it, so he sent people to Dorgon for help and asked for borrowing troops.

"Bang bang" With two dull gunpowder gas expansion sounds, two sky-rushing cannons sprayed fire. Before the two flowering artillery shells were released, the scorched gunpowder gas expanded, igniting the cork tube fuse on their heads. The fire-lit shells rose into the air and flew to the highest point, carrying the fire, and smashed it hard towards the head of Xiluo City like a meteor of fire.
