After Yuan Keli learned that he had made a breakthrough at a distance of about one and a half miles north of Dongzhimen, he did not hesitate to immediately order the other three demolition teams that had already completed preparations to also attack. Of course, the reason is simple: if such a method is continued after a certain period of time, it is difficult to say whether it will achieve very good results.

A violent explosion came from a short distance from a short distance from the Andingmen. This time, there were sixty demomen who piled up about 5,000 catties of black powder at the fastest speed to start blasting. Although no holes were dug, the huge impact and qi waves still knocked down the city walls within a radius of more than ten zhang, and even the entire outer city of the city seemed to have many cracks under the violent vibration. The elite of the Ming army that had been concentrated also took the opportunity to attack.

Although the distance from the Imperial Horse Supervisor was relatively close here, the Teaching Brigade Brigade and even the auxiliary personnel who were on duty on a rotational basis quickly rushed over and curbed the spread of the Ming army that broke the city, but at this time and the inner city test, a consolidated military formation with a radius of 100 steps had also been formed. More and more heavy shields were also concentrated in the hands of the breakthrough Ming army at this time, forming a hollow phalanx tortoiseshell formation composed of huge heavy infantry. Unless the defenders mobilized enough artillery fire in a very short period of time to launch targeted fire, it would be almost impossible to shake the Ming army that was holding the breach and increasing its troops in the city.

Of course, at this time, rumbling cannons began to be heard in the direction of the Forbidden City. After all, because of the relatively long distance, the sound of the cannon was neither dense nor very loud, but in just a few moments after the sound of the cannon came, more than 2,000 heavy shotguns of six or seven taels fell within a radius of about 200 steps above the direction of the breakthrough north of Dongzhimen. At least 100 of the 3,000 or so Ming troops gathered within the breakthrough within this range, and even about 2,000 Ming troops as reserves, were instantly knocked down under the projectile blow from the sky in the dark night, and they were almost either dead or disabled. The heavy shield on his head and even the armor on his body did little to help. Even if the six-tael projectiles, which were not very fast, did not break the armor, the fierce blunt blow was difficult for the soldiers to bear.

If it's an ordinary rabble or second- or third-rate armed people. In the case of thousands of people suffering more than 100 instantaneous kills, even if they do not collapse, they will quickly retreat. However, these elites of the Ming army who broke through the direction and broke through the city were relatively elite, and they were not comparable to ordinary Ming troops, so they only attacked for a while, and did not retreat quickly. But then the second and even the third blow came in a few breaths. At least three or four hundred people were knocked to the ground in a very short period of time, and the phenomenon began to shake thousands of elite soldiers completely. When the blow lasted about two minutes, the enemy troops, who could no longer withstand the shelling, began to retreat.

The officers and men of the Guards Battalion and the Brave Guard Battalion, which had been suppressed and pushed into the fortifications, also took advantage of the situation to launch a counterattack at this time, although their combat effectiveness and equipment were inferior to the enemy troops at the breach, but under this closely combined infantry and artillery coordinated attack, they still quickly gambled the enemy troops outside the breakthrough of about ten zhang.

Almost the next moment, the heavy bombs in the darkness began to fall one after another within a radius of about 200 steps from the breakthrough near Andingmen, at this time more than 10,000 Ming troops had broken into the city, and there were at least 5,000 people outside the city wall in this range as reserves. Under the blow formed by more than 2,000 heavy bombs of about six or seven taels, 300 people were either killed or wounded on the spot, and in just six rounds of firepower within two minutes, the Ming army that broke into the city suffered nearly 2,000 casualties.

It turned out that near the nine gates in the previous battle, it was found that the city gate could be easily blocked by means of pressure injection and artillery bombardment of small and medium-sized firearms. The eighteen two-thousand-pound barreled artillery pieces and even the thirty thousand-pound body-barreled heavy artillery pieces captured in the Linqing area owned by the entire team were concentrated and deployed in the north of the Forbidden City, about the center of the entire forty-nine city. When the artillery is fired with the maximum standard charge, it can make a heavy bullet of about six or seven taels hit the muzzle velocity of sound, and the maximum range is almost half of the range of firing a sealed live ammunition due to the proportion of wind resistance, but even then it is six or seven miles away, and it is completely possible to concentrate support near the central position to most of the city except for a few areas in the northeast and southeast corners. Although the projectile specifications are very tightly controlled, and the long-barreled artillery is conducive to the concentration of shotguns, the dispersion range of heavy shotguns at a distance of nearly three kilometers is still as high as a radius of about 200 paces and about 300 meters, which is still a dense boundary of about six or seven percent, and many shotguns are scattered to a longer distance. But even so, it seems that it is enough to cooperate with the defenders to defend.

The 48 heavy artillery pieces deployed north of the Forbidden City thus seem to form an enlarged version of a circular defensive position similar to that of the United Nations Army during the War to Resist US Aggression and Aid Korea. Perhaps, judging from the rate of fire of artillery, even the killing range and even the accuracy index, the comparison of the firepower level of the so-called "heavy artillery" in this era may not even be one-fiftieth of the howitzer of the United Nations Army, and the effectiveness of about one percent in the range of the mortar is considered good. However, there was no doubt that the attacking Ming army required at least ten to twenty times the density of troops, which was already denser than the regular army of the early volunteers. In addition, in terms of casualty tolerance, even the so-called "elite of the Liaodong Army" selected is undoubtedly several times worse than the infantry company of the Volunteer Army. It's almost a gap of six or seven percent in the offense. In this way, the breakthrough opened by the Ming army in multiple directions throughout the night was finally contained by the heavy artillery that opened heavy fire in conjunction with the defenders.

The artillery deployed in the Forbidden City was not without its costs, firing with twice the standard charge and a consistently high rate of fire, plus the heavy artillery had been used many times before, resulting in three explosions in just one night. The explosion of at least one 2,000-pound cannon and two barreled guns killed and injured more than 100 gunners and even auxiliary personnel, and a lot of ammunition was damaged. Compared with the role played, after all, it still blocked the assault of the Ming army in all directions.

Of course, although the breakthrough of the formation system was resisted, there were still many sporadic stragglers who infiltrated and broke into the city, and these forces were often relatively elite elite soldiers, and it seemed that the streets and alleys were not destined to be peaceful throughout the night.
