Quan Zhuo was ordered by Wang Zheng, the general soldier of Shandong, to lead the expanded cavalry battalion of 2,000 people of the Shandong Army to travel day and night, and rushed outside Kaifeng City first.

The two sides were originally inseparable from each other, and they fell into a bitter battle, Hao Shaoqi, who was in charge of attacking here, never expected that such a cavalry would suddenly rush behind him, and before he could give any orders, the other party had already come to him.

The cavalry of the Shandong army had bright scimitars in their hands, plus a suit of iron armor, which looked shiny from a distance, and the weapons on their bodies were specially made to facilitate immediate combat.

The scimitar is an imitation of the scimitar and tiger head knife of the Mongolian light cavalry and the Jurchen iron horse, take its essence, go to the dross, use so many battles, many veterans react very well, both lightweight, lethal and sufficient.

In addition, in order to increase the power of the charge, the cavalry of the Shandong Army also refined a pair of Chinese-style cavalry spears, and the main centaurs were naturally the Portuguese led by Jem, which was an imitation of the Western cavalry spear.

In the past, the cavalry of the Shandong army had no long-range firepower, but before coming this time, Wang Zheng had recognized this problem and rushed to make a batch of three-eyed guns and send them to Quan Zhuo.

Having said that, at that time, Wang Zheng originally wanted to get the principle of the flintlock pistol from Jem, but Jem didn't know much about it, so he had to smile at the time, after all, he was just an ordinary voyage explorer, and it was good to know so much, so he didn't force it in the end.

However, although the flintlock pistol has no hope for the time being, the cavalry still has long-range firepower, and it is impossible to use bird guns and thunderbolts.

This is a wake-up call for Wang Zheng, this somewhat backward three-eyed gun seems to be the best firearm that the cavalry can use, after repeated discussions with the staff of the Military Council, finally Wang Zheng decided to rush to a group of three-eyed guns to assemble the cavalry battalion.

"Upper guns!"

When he rushed to a distance of more than a hundred steps from the back of the thieves, Quan Zhuo shouted, and the cavalry of the Shandong army took out the three-eyed guns hanging between their calves.

The effective range of the Three-Eyed Gun is 100 paces, but at this time it has no lethality against most of the enemy troops, and generally plays a deterrent role, after many tests on the shooting range, Quan Zhuo found that the best range of the Three-Eyed Gun is 30 paces.

Combined with the records in Zhao Shizhen's "Weapon Spectrum", although the overall accuracy of the three-eyed gun is low, it can have a high accuracy within 30 steps, and according to some veterans of Liaodong, it can even penetrate the heavy armor of the Tartar at this range.

However, in a cavalry battle of hedge or charge, a distance of thirty paces is enough to fire, and most people will choose to fire in three volleys instead of bursting.

The opponent in front of him is not a Tartar wearing heavy armor, the homeless camps that break into the army account for the majority of the proportion, and now light armor and standard clothing have almost been popularized, but the elite combat power is still not enough, and even the old battalion has not been able to fully carry heavy armor.

Most intruders are able to pierce their armor if they are fired at less than eighty paces, and of course, this is only if they can be shot.

The three-eyed guns of the cavalry of the Ming Dynasty were upgraded due to the low hit rate of immediate firing, absorbing the previous defects, and in order to improve the hit rate, the three-eyed guns of the Shandong army were upgraded.

In this situation, the three-eyed guns of the cavalry battalion were equipped with scattered bullets, "two or three leads per gun", and in order to increase the killing effect at close range, two or three lead were used for each gun.

If it is against the Eastern Prisoner, the requirements for the cavalry are higher, and it is necessary to fire three rounds within thirty or forty paces, and most people have a spectrum in their hearts about the opponent's armor, so Quan Zhuo decided to prepare with a gun within a hundred steps as soon as he entered it, and start shooting at eighty paces.

In fact, at the beginning of the Ming Dynasty, there were already cavalry firearms, but rarely fired on horses, generally dismounted in a formation to put three-eyed guns, if it was too late to dismount, they were each according to the team for the long battalion to take turns to fight and fight, there was no retreat.

According to some old craftsmen who came from the guardhouse, the three-eyed gun is generally fired in three bursts when used alone, and only when it is combined with the shotgun, in order to make up for the shortcomings of the shotgun's weak firepower, it will fire three rounds in unison.

The three-eyed gun can choose whether to combine the three leads together according to the battlefield situation, continuous or unison, Quan Zhuo has already understood clearly from the craftsman in advance, and the imperial generals in other places, although many people know that the three-eyed gun can be fired in a row and three bullets in unison, but they have not thought about the circumstances under which the three-eyed gun should be fired in a row and three bullets in unison.

"Bang, bang, bang—"

The continuous loud sound suddenly sounded in the rear of the breaking army, and within 80 paces, the cavalry of the Shandong Army began the first round of salvos, and the second round began about 50 paces, and by the time it was 30 paces, it had completed three rounds, and drew out its cavalry to charge.

Many of the rogues were suddenly hit and howled, but most of them were not fatal wounds, but they were incapacitated for a long time.

The continuous firing of the three-eyed gun not only had an earth-shattering sound, but also instantly emitted bursts of white smoke, and the cavalry of the Shandong Army passed through the white smoke in the eyes of the Liukou, and crashed into the rear of the Liukou.

Hao Shaoqi in the formation was very unlucky, he was hit in the left rib by a stray arrow, he endured the pain, covered the wound with his rough big hand, gritted his teeth and said:

"Send someone to inform King Chuang and the military division, and let Li Guo's horse team hurry over to support!"

Hearing this, those old battalion soldiers did not run away directly, and a leader looked at Hao Shaoqi's bleeding left rib worriedly, and said:

"This is the cavalry battalion of the Shandong Army, it has never come out alone, it must be followed by most of the people, and it is too late to retreat now!"

"Nonsense, Kaifeng was knocked down immediately, how can you give up halfway!?"

Although Hao Shaoqi said so, his face was getting more and more pale, and many old battalion soldiers surrounded him, and at this time, the ironclad Shandong general was rushing towards this side with a spear and a prancing horse.

The rear of the army was attacked, and it was instantly defeated, and Hao Shaoqi was seriously injured and unable to continue to command the formation, so far it was already a scattered rout, and the army was defeated like a mountain.

Quan Zhuo stabbed to death the intruder who came up to meet him, and the tiger was eagerly looking for it in a black brain, and suddenly his eyes froze, and he saw Hao Shaoqi, who was surrounded by a group of white-clothed old battalions.

He thought it was Li Zicheng, and immediately raised his riding gun and shouted:

"That's a thief, you can't let it go!"

Although there are many people on the other side, most of them are cannon fodder composed of homeless people, and a few horsemen are used to give orders, the most precious, at first they were safely guarded in the center, and now they have long been scattered to the leaders of the besieging troops to report the situation.

The cavalry battalion charged back and forth in this situation, stabbing the horses everywhere along the way, anyway, the horses did not stop, and the thieves who were slow to react and still stood in the way were either knocked away by the horses, or were stabbed to death by the horses from afar.

Quan Zhuo led the cavalry battalion of the Shandong Army to be invincible, and in one fell swoop defeated the Hao Shaoqi army besieging the south gate.

Chen Yongfu smelled an opportunity and immediately organized a counterattack, and the Ming army soon regained control of the crumbling southern city wall.
