After a violent explosion sounded, a black shell emitting white smoke erupted directly from the three-foot-long barrel, and with a whistling sound, flew towards the Mongolian artillery position outside the city.

The moment the mortar beside Wei Zheng opened fire, the thirty-six mortars lined up along the city wall followed, spewing out orange-red fireballs mixed with a large amount of black smoke from the muzzle.

Of course, more than thirty shells also flew towards the Mongolian artillery positions with a whistling sound.

You know, these shells are not solid shells, but flowering shells that can explode as soon as they explode ...

After more than 30 shells exploded one after another, the Mongolian artillery in a row was covered by the smoke generated by the explosion of the shells in the blink of an eye.

As for the hundreds of fragments of shells from the explosion of the shells, an impenetrable storm of steel quickly formed in the Mongolian artillery positions.

The Mongols, who were standing in the artillery position and constantly firing artillery, did not expect that the Zuoyun garrison, which had been silent for several days, would still hide so many artillery. What's more, the shells used by these artillery pieces turned out to be rare flowering shells.

So, the moment the shells whistled and exploded, hundreds of Mongolian artillerymen, except for dozens of people who were busy. The others were all standing in the artillery position, and with a face full of pride and arrogance, they looked at the Zuoyun city wall that was being attacked...

However, in the blink of an eye, the fragments of the flying shells had swept towards them.

Without wearing any leather and iron armor, the fragments pierced through the bodies of these Mongols and entered their bodies.

In an instant. Hundreds of Mongol artillery. and they were all harvested to the ground. As for the barrels of dozens of artillery pieces leaning against sandbags. It was also knocked to the ground by the sound of shells exploding......

Of course, this was only the artillery counterattack, the moment when the first round of shells flew out of the barrel. A regiment of musketeers, also at the same time, protruded from the battlements with a black hole in the barrel of a musket. Then, without hesitation, he pulled the trigger and shot a buckshot.

"Bang bang..." More than a thousand buckshots, with a whistling sound, flew out of the city.

In the face of a dense crowd of Mongol musketeers and 5,000 attacking troops, these whistling lead bullets did not need to be aimed at all, and they could hit their targets in the midst of the dense Mongols.

The first round of lead bullet had just passed, and the second round, and even the third round of musketeers, who had already been on standby, had already pulled the trigger without hesitation and shot the lead bullet in the chamber.

After three rounds of buckshot. In the middle of the dense Mongol army, a huge gap has appeared......

Of course. This buckshot has no intention of stopping.

At the rate of fire of the flintlock musket, the first row of musketeers had already reloaded by the time all three rounds of lead bullets were fired. Pingduan held the musket in his hand, and through the lookout, pulled the trigger on the seventy-step Outer Mongolian army.

In this way, rounds of buckshot, as if they did not need money, continued to pour on the Mongols.

At this time, Dorgon, whose eyes had been focused on the battlefield and was confident in the attack, finally realized that something was wrong, and showed a shocked expression.

frowned, and shouted loudly: "It is the Tiger and Par Army that is holding on to Zuoyun, not the garrison... Only the Haw Par Army is equipped with this new musket with great power and fast rate of fire..."

"The reinforcements sent by the Shanxi Governor's Mansion have already arrived in Zuoyun City......"

"What are you still doing in a daze, ordering the warriors to retreat immediately... In particular, our firearms units must be withdrawn. Otherwise, in the next battle, our firepower advantage in front of the Han people will disappear completely......"

"Toot toot... A different horn sounded quickly on the battlefield where the battle was in full swing.

Hearing the sound of the trumpet, the Mongols, who were attacked and in confusion, quickly retreated to the rear.

Not to mention, more than 10,000 people gathered on a small battlefield, coupled with the obstruction of a large number of corpses, it is obviously a whimsical thing to want to withdraw in a short time.

In such a situation, the sound of the horn of retreat not only did not save their lives, but made them even more confused.

And at this time, more than 4,000 musketeers did not miss this excellent opportunity to kill. With your fastest rate of fire, reload, pull the trigger, and shoot the Mongol cavalry outside the city.......

After firing three rounds of shells at the Mongolian artillery positions, more than 30 mortars had already turned their muzzles and poured shells into the dense center of the Mongol troops......

Mortar shells that exploded like rain overhead... Directly in front of them were densely packed, like a raging storm, and the lead bullets that kept sweeping towards them...

Under the attack of these two deadly weapons, the already chaotic formation of the Mongol army became even more chaotic at this moment. Of course, their losses are getting bigger and bigger.

At this time, in order to survive, there were less than 6,000 musketeers left, like lost dogs, directly dropped the muskets that stood in the way, and fled frantically to the rear...

However, these Mongols did not expect that the Haw Par Army they were facing was not an ordinary officer army, and the muskets in the hands of the Haw Par Army were not ordinary muskets, but flintlock muskets with an effective range of more than 150 paces...

Even if there is no obstruction, these Mongols will need a cup of tea if they want to retreat from eighty paces to one hundred and fifty paces away, not to mention the chaos in front of them, the battlefield full of corpses and muskets...

Therefore, the dense Mongol army, every step back, suffered heavy losses under the blows of muskets and artillery.

When the dense Mongol army completely withdrew from the range of muskets, and under the threat of a full 300 paces of mortars, they all retreated back by as much as 500 paces......

Of course, although the Mongol army retreated, a thick layer of corpses had fallen on the battlefield between 80 and 150 paces outside Zuoyun City, under the attack of 4,500 muskets and more than 30 mortars.

The 8,000 muskets abandoned by the Mongol musketeers were also scattered among the corpses.

Under the stunned gaze of Zuo Yun garrison Wang Yunshan, Wang Feng, who had a stern face, ordered very unexpectedly: "This general order: artillery cover, musketeers, attack immediately... Confiscate all the equipment that the Mongols left outside the city....Even if the Tartars had the ability to produce and craft firearms on their own, 8,000 muskets and dozens of artillery pieces would be enough for the Tartars to build for a while. ”

"As long as we capture and destroy it, at least for a short time, the Mongol army outside the city will no longer have firearms units that threaten us..."

"With the current strength of the Tartars, he Dorgon has absolutely no capital to fight a war of attrition with us" (to be continued......
