Everything happened in an instant, and Chen Kai's thoughts flashed through his mind like lightning, and the flash illuminated the offset of the cannonball, which also illuminated the location of the cannonball.

The solid shells can cause limited damage, Chen Kai thought about tossing the flowering shells, but the weight of the shells will also affect the range and accuracy, which makes him have to put this idea on hold for the time being. However, the afterimage that flashed in front of him made him feel a little remorseful, but this remorse had not yet been implemented, and he saw that the cannonball directly hit an ox cart carrying gunpowder. Next, there was a deafening explosion, which broke out on the north side of the main position of the Qing army!

Conducted by the deflagration of gunpowder and the rapid friction with the air, the cannonball is a hot iron ball, even if it floats there openly, it is enough to burn people and things.

This cannon, straight into the ox cart, the huge kinetic energy of the cannonball easily broke through the shell of the barrel, its hot temperature and friction with the barrel ignited the saltpeter component of the gunpowder in an instant, and then the saltpeter, sulfur and charcoal instantaneously reacted, when a wooden barrel exploded, all the barrels on the car also disintegrated instantly under the huge vibration of the explosion, and at the same time exposed more gunpowder to the high temperature of the explosion, just the moment that light flashed, the barrel, the ox cart, and even the auxiliary soldiers of the ox and the car, Everything disappeared in an instant.

The explosion was not just a small area, the explosion of a barrel of gunpowder was enough to drown the area near the left in a sea of fire, not to mention a dozen barrels of gunpowder on an ox cart, covering a large area in just the blink of an eye.

The explosion of gunpowder, the shells and even the heavy body of the Hongyi cannon also flew up and smashed down under the huge kinetic energy of the explosion. Whether it was the explosion of fireworks, or the disturbance of the shells and cannons on the left, an ox cart carrying gunpowder exploded, instantly igniting more ox carts around it, and those ox carts were all loaded with a large amount of gunpowder!

"Seventy-three red cannons, each with four hundred cannons and an equal amount of gunpowder. If it is calculated according to Sun Yuanhua's standards, then even if all the Hongyi cannons of the Qing army are twelve-pound cannons, they will be 280,000 catties of gunpowder......"

At the same time as the sound of the explosion came, the number had already exploded in Chen Kai's mind, and this moment was something that Chen Kai had never been so sensitive to numbers in his years of school, even to the point that it made him feel terrified. Judging from Fang Cai's observations, not all of the Qing army's artillery teams went around from that area to the rear of the formation, and more than half of them had to bypass another area in the south. Counting the consumption of the above fire, as well as the habit of unavoidably exploding, the artillery crews of the Ming and Qing armies will tend to put less gunpowder, and the gunpowder covered in that area may not be able to reach the 100,000 jin mark. Ke Rao is of such an order of magnitude, and its explosive effect is by no means imaginable by ordinary people.

Carts, horses, oxen, brave vassal soldiers, and even heavy ox carts, gun carts, and cannon barrels were not much stronger than confetti in the face of the power of chemistry. The energy of the gunpowder explosion tore everything in the area apart, shook it away, and even vaporized without a trace.

The explosion was continuous, with ox carts and barrels of gunpowder covering the entire area, and the release of energy expanded to a farther area, from the flank and rear to the main position of the Qing army. Rao is Jingnan Domain's feudal soldiers left only those reserves and auxiliaries in the main position, and a lot of them were affected, especially the auxiliaries who were assisting the artillery crew in carrying the artillery in that area, and they disappeared in the explosion one by one.

In a trance, Chen Kai even vaguely saw the mushroom cloud rising, but he quickly shook his head, but it was still the explosion that seemed to squeeze the sun in this winter into a dull one.

The huge shock wave was affecting the main position of the Qing army, which was quite far away, and even far away to a distance of one or two miles away, the Qing army besieging the city heard this loud noise in the rear, and at the same time, it no longer cared about the battle in front of it, and turned its head to look at the fire in the main position of the Qing army. And their opponents did not take advantage of this once-in-a-lifetime opportunity to kill the Qing army in front of them, who had been shocked to the point of blank brains, and just like the former, they looked at everything in the distance in a daze, and they couldn't even swallow their saliva.

At the lower level of the main fort, a sword and shield soldier of the Qing army was still easy to climb halfway, and was waiting to jump a few times, directly climb the low city wall, and seize the first to ascend. At this moment, like all the Qing troops around him, as if his soul was sucked away by the loud noise behind him, one foot hung in the air to look back. And just above him, the Ming army, who was about to aim a city brick at what he had thrown down, also raised the city brick high with both hands, but never threw it down, just stood there like a chicken, his eyes full of disbelief.

In fact, from the very beginning, Chen Kai was giving the Qing army the illusion that with those Hongyi cannons firing at the Qing army, it was just that the number of Ming artillery they produced was not as good as theirs, and the firing range was similar to theirs.

This cannon didn't need any power, as long as the cannonball was sent to an area not too far from Geng Jimao, as long as the Qing army realized that even their commander was within the range of the Ming army, and he was nothing more than a person waiting to die, it was enough to destroy the last bit of morale of the Qing army, and then it was nothing more than a brutal pursuit.

But now, the shelling is crooked, but the effect is several times better than expected. Not to mention, the series of explosions alone was enough to attract the attention of the Qing army on the front line, which was more shocking than the scene of just killing Geng Jimao!

A moment later, the Ming army, which had already consumed a lot of physical strength in the previous battle, could no longer hold on, and threw the city bricks down. And the figure looking back didn't bother to use the shield to unload the force, and straightened up the falling power of the city bricks with his head with an eight-petal helmet and a "lightning rod", and then fell off the ladder, leaving only a "ah" scream, and his life came to an abrupt end.

However, the screams seemed to open a new movement. The Qing army on the battlefield could no longer care about military law, merit, slaughter, rape and plunder, and the bloody nature of the brave battle, only after this summer stopped, the screams instantly resounded across the earth, and for a while it seemed that even the distant explosions were suppressed.

"Defeated, defeated!"

"The prince is dead, the prince was blown up by the pirates!"

"Haikou intercepted our back road, run quickly, it's too late if you don't run!"

“……”

The morale of the Qing army collapsed, whether it was the green battalion or the once invincible feudal soldiers, there was no longer any courage to fight against the Ming army at this moment.

Everything came too quickly, and Chen Kai, who had already planned for a long time, did not react at the first time, but Li Jianjie, who was ready to attack in Beibao City, immediately scolded the gatekeeper to open the city gate and let his cavalry out.

The gate in front of the fortress is connected to the Half Moon Fort, and there is a considerable height difference between it and the ground, so Li Jianjie has to fight through the back door. There, already the Ming army had crossed the pontoon bridge and was massing on both sides. But as soon as the city gate opened, Li Jianjie roared, and when he rushed out with his cavalry, he almost brushed the edge of those Ming army columns to complete the turn, and rushed to the north of the fortress.

The Qing army besieging the city has begun to abandon those siege equipment and turn to flee, and the same is true of the green battalion soldiers and reinforced feudal soldiers who fought with the Ming army outside the city.

"Kill Geng Jimao!"
