The entire attack area controlled more than ten miles of continuous fire, the continuous explosions above the city, and the light from the ignition thrown by their own trebuchets reflected the enemy defenders under the city head, leading to the city head. The artillery bombardment carried out by the captured second or third general's artillery was also launched at this time at the fastest speed under the command and guidance of the corresponding position.

As night approached, the distance and direction of each section of the city under the control of the enemy were determined by estimates, and the approximate charge and direction were determined through the experience accumulated from many firearms tests in peacetime. When the makeshift artillery teams were ready to fire, the gunners, who knew what they were going to attack, quickly launched the attack as fast as they could.

"The direction is half past ten, the distance is fifteen sections, the charge is three into five, get ready!" An officer of the teaching brigade quickly commanded the man in a bunker behind the city walls. At this time, the practical effects of the cultural extraordinary, brought about by more than a year of preparation, began to be truly felt. This kind of firing with a predetermined orientation and standard charge, especially with relatively rudimentary firearms and gunpowder, was an unimaginable test even for the Western gunners of the time. However, it is not very difficult to understand the momentum pendulum and there are many measured teaching brigade officers.

The power of the second or third general's cannon, which is only 100 catties to 100 catties, is not very great, and when the charge standard is about one-third, it can often only shoot seven or eight catties of shells with the muzzle velocity and firing range of an ordinary bow and arrow. But even so, the power is almost comparable to that of many human trebuchets in the Middle Ages. Although it is not possible to threaten the overthrow of the castle head that is standard in the "Castle Guarding Record", it becomes a deadly threat to those ladder trucks and many planks on the top of the city. In the case of lower charge standards, the sustained rate of fire of these guns that were not of very good quality also became higher, and the eighteen medium and light guns that were shelled in a group of companies could often fire nearly 100 rounds of seven or eight pounds of shells in about a minute, so that the road leading to the city was also destroyed by the ladder composed of ladders that led to the city.

If it was daylight, the Ming army, which had superior strength of archers and gunners outside the city, could easily use the archers and even gunners to launch a fierce counterattack by judging the direction of those shells. However, at night, even if the person who was smashed felt the general direction of the shell, it was impossible to accurately counterattack it.

Yuan Keli still expected the counterattack after nightfall, and when the battle situation at the head of the city seemed to be one-sided and passive, he also ordered the prepared catapult to launch a gravel covering blow, and at the same time, ignited the blasting crater that had been prepared long ago and launched a blasting attack to suppress it.

Because the successful experience of the main force of Jianzhou spread even early on, with the cover of the army during the day, the Ming army outside the city also deployed many blasting pits to launch stones. It's just that this kind of attack is difficult to accurately attack the target in the city or the city, and it can only be used to cover the attack.

For a moment, the explosions of black powder grenades, far more than those like large artillery battles, rang out from outside the city one after another. At this time, the officers and soldiers of the commando attacking at the head of the city could only do their best to squat down and gather together, and set up a tight protection with shields, striving to avoid casualties to the greatest extent. Fortunately, the enemy army at the head of the city, which was destroyed and repulsed, did not take advantage of the situation to launch a counterattack at this time.

The archers in charge of projectile suppression and cover within the earthen walls of the city wall heard the continuous explosions like a sea of mountains, and they all took refuge in the ballade pits that had been prepared long ago.

The fierce blow finally fell to the ground under the cover of night, and hundreds of thousands of pieces of rubble, ranging from a pound to a few pounds, covered almost all the areas of the battle at the head of the city, and even the area within the city walls that was at least a hundred paces deep. Although the relevant preparations had been made for a long time, hundreds of the more than 10,000 officers and soldiers who were responsible for supporting the battle at the head of the city still suffered blows under this fierce blow, and almost they were either killed or maimed.

The commandos at the head of the city also suffered a serious blow, those individual shields did not suffer minor injuries or fractures when they resisted the pounds or so of stones thrown from them, and when they were hit by stones weighing several pounds as fast as a crossbow, the seemingly solid defense also seemed to be like paper.

After this fierce blasting attack, Yuan Keli quickly ordered another siege support, and the enemy troops who had occupied the city head with heavy casualties in the coordinated assault quickly put hundreds of commandos in a desperate situation again after receiving a steady stream of reinforcements from the team that climbed the city head.

It's just that this passive situation doesn't seem to last long, when the inside of the city wall once again continued to shoot a continuous rain of arrows and black powder grenades that continued to explode, and the artillery array was once again revived, the besieging Ming army, including Yuan Keli, knew that the previous huge preparations did not have the expected effect, and the battle situation seemed to take a sharp turn again.

At this time, Yuan Keli also understood that in the face of such a well-planned coordinated counterattack by the defenders, the key to success was to be able to break into the city and disintegrate the opponent's defense system from the inside of the city wall. For this, even the biggest risk is worth it.

Therefore, he did not hesitate to attack the elite who had been beaten and opened in the direction of Andingmen and Dongzhimen in the direction of Andingmen and Dongzhimen, which had already been beaten and opened, and once again invested heavily in the encouragement of the elite. This time, it was no longer ordinary officers and soldiers or even cannon fodder who attacked the city gate, but the elite soldiers who also wore armor and shields and were heavily armed to protect the standard of the main heavy infantry in Jianzhou. Almost at the same time, hundreds of large and small generals' cannons in the direction of the two city gates that were concentrated also launched at this time with heavy artillery fire, so as to weaken as much as possible the ambushes and threats that might be encountered after attacking the city gates. The war lasted until this point, and many people could see that even the most rudimentary artillery was a more effective means of cover than traditional siege engines. Hail-like bullets continued to fall into the city gates, and even on many houses within the city walls, bringing bursts of shattering.

However, the trebuchet also seemed to work at this time, and the continuous projectile of firelight seemed to illuminate the city gate, at least making Yihe look less frightened, which also gave the elite of the Ming army a hint of courage to move forward, and advanced forward under the cover of a continuous rain of arrows.
