Although at least one-third of the more than 100 firearms of the Ming army, mainly the second general's cannon, had been sampled, because these firearms had been fired many times in the previous night battle, Xiao Xuan had no way to guarantee the reliability of these firearms. One of the great strengths of the team in charge of Xiao Xuan in the entire battle is that many combat details and processes have been deduced on the previous sand table and even on the school ground of firearms testing, and many links have been specially prepared.

Most of the bunkers in the entire Imperial Horse Guard position were actually artillery forts that could be transformed, equipped with specialized recoilless wooden gun mounts and aiming rods. An aiming rod is a pole equipped with a gravity boom or even an angle bar. And the recoilless cannon is just a bamboo barrel that has been hollowed out and can be installed with a second or third general cannon. When firing the cannon, the cannon can be encased inside, and the personnel can temporarily leave after ignition. The recoil causes the gun to fly backwards quickly. In this way, even if there is an explosion, the gun will not be damaged. As for the target of the attack, it was mainly in the direction of Zijin City. Because according to the pre-war deduction, the most likely place to retreat after the enemy's attack failed was the Forbidden City, which could barely be used as a defense.

Of course, it was not the more than 100 guns of the Second General that fired first, but a number of thousands of firearms in groups of ten platoons that were temporarily prevented from being captured in the excavated trenches. The general direction of the target is also the direction of the Forbidden City, according to the previous test, even if the charge within the maximum safety range, the theoretical ejection range of the ordinary fire gate gun or the three-eyed gun is not more than about two miles, and the fire from the northwest direction of the Imperial Horse Prison to the southwest, even if the dispersion error is comparable to the maximum range, it can cover the entire Miyagi in a large area.

In order to make the most of the individual firearms that had been captured and did not seem to have much value in night battles, not only the main force of about 2,000 officers and soldiers was engaged in the process of firing guns and diffuse like kicks for the New Year, but even the more than 2,000 artisan battalions were mostly replenished. The craftsmen in Xiao Xuan's team were not considered laymen to these things, and more than 4,000 people continued to fire at a rate of more than 3,000 rounds per minute under the lighting of torches, which lasted for about half an hour. As expected, these firearms were blown up at least dozens of times or other accidents, even if the precautions were not fired on the hand, and five careless teenagers and craftsmen were injured as a result.

The continuous fall of firearms and lead bullets from the dark night before dawn covered the entire Forbidden City, and after flying over a distance of about one or two hundred paces and more than one or two miles, most of the falling projectiles had little power. However, even if a lead bullet of about 100 joules hits a cannon fodder with little protection, it can often get into the flesh and blood, causing death and injury. The vulnerability of the human body is exposed to people who simply do not have decent protection.

After more than 100,000 lead bullets that fell into the palace brought about two or three hundred deaths and injuries to the thousands of people exposed outside the palace, although the rest of the people could not find a way out of the palace wall for a while, they also gradually gathered in the corner of many palaces and palace wall buildings to avoid danger.

At this time, the sky seemed to gradually brighten, and many temples in the Forbidden City began to shine in the gradually clear blue morning light. At this time, the live shelling of the captured second general's artillery, which had already been ready for battle within half an hour, began. Although the muzzle velocity of the body tube weighing more than 100 catties is not fast when firing seven catties of sealed live ammunition, it can also launch about seven catties of sealed live ammunition to a strong crossbow general muzzle velocity of about one-third of the speed of sound under the extreme strong charge, although it cannot smash many walls in the palace when it falls into the palace, it forms a ricochet in many palace channels, and can barely threaten the roof, and smash many internal floor surfaces that are not as solid as the exterior walls from the brick roof with rapid momentum.

This once again brought great deterrence to the defenders, and the artillery bombardment, which lasted for about half an hour until the sky was completely bright, fired several thousand seven-pound shells one after another. Because of the vast area of the Forbidden City, these thousands of shells did not cause the remnants of the enemy in the buildings and corridors to suffer too serious casualties, but only caused hundreds of casualties, but such a blow still made the enemy troops hiding in the denser buildings in the palace area in the north-central part of the Forbidden City involuntarily retreat to the south. In the face of indiscriminate live shelling, the backbone of the officers and even the people used to supervise the war also faced the same risks as the soldiers, so although they knew that if they retreated to a place south of the Qianqing Palace where there were more squares and relatively few shelters, they would encounter a greater risk of casualties, the crowd still involuntarily fled towards the noon gate.

At this moment, under the cover of the cavalry team of the Imperial Horse Guard, the general artillery team that had been waiting in the south of the Forbidden City for a long time began to speak, and without any intention of breaking the armor, Xiao Xuan directly set the power standard of the light shotgun at the estimated top and bottom of 100 joules. In this way, even if it is tens of joules, the end power can also enter the flesh and blood, forming a kill. When a large general's cannon unfolds its firepower regardless of the risk of exploding, it can at least use a high-standard charge to fire nearly 1,000 three-eyed guns or firegate guns at a time, and more than 30,000 projectiles are covered like a rain curtain, and the enemy troops who retreat to the front of the Forbidden City and intend to retreat and flee from the vicinity of the noon gate are bleeding at the first time, and the scene is chaotic.

In fact, even at this time, if the enemy forces in the Forbidden City were a stubborn opponent, they would not have been moved by the early shelling and firearms threats. After all, with the old Ming weapons and firearms that Xiao Xuan mastered, no matter how much he tapped the potential, he was not capable of covering the entire Forbidden City and forming a large proportion of killing. But for those remnants of the enemy who have no casualty tolerance for half of them, many tactical arrangements are also enough to use.

What Xiao Xuan didn't expect was that when he had suffered heavy losses in the first half of the night, the willpower of the 10,000 remnants of the enemy, who seemed to be not small in scale and convenient to defend, was even weaker than he imagined, and many people had lost the courage to resist and even flee under the fierce shelling and bullet rain.

It wasn't until under the continuous three rounds of fire that thousands of people were killed and wounded under the barrage like rain, and many temple tiles began to be hit by live ammunition, that someone finally came out of the wall, as if they were holding a white flag and planning to surrender.

Xiao Xuan, under careful thinking, did not let the firearms continue to stop firing, and the continuous cannon sound continued to rumble in bursts, from the Qianqing Palace to the Cold Palace, and even many palaces were affected, and when it was close to noon, the palace city, which had been somewhat dilapidated, finally calmed down, and seemed to be as silent as it were.
