At the same time, Yang Lin sent envoys to the Great Western Army, hoping that the two sides could strike and join hands to fight against the Manchu Tatars.

Seeing that the volunteers wanted to make peace, Zhang Dingguo was furious, and fought during the day, if it was not for the rain in the sky, if it was not for the arrival of the army of Bai Wenxuan, most of the casualties in his troops would have been lost.

In the past, it has always been said that the firearms of the volunteers are sharp, and it was only during the day that they realized that what they said was true.

The musketeers of the Volunteers can not only shoot, but also shoot iron sand and lead bullets on the battlefield, and the smoke is billowing out, and they can penetrate the iron armor at close range, not to mention the cloth shirts and quilts worn by ordinary soldiers.

What's even more incredible is that they are not afraid of hand-to-hand combat at all, unlike in the past, musketeers did not need close protection from other arms with their guns, but loaded with bayonets to fight like soldiers.

Looking at the dead corpses all over the ground, most of them were soldiers of the Great Western Army, and many of them were old subordinates who had followed him for many years.

Now that the reinforcements have arrived, it is raining again and again, and the sky is moving to the Great Western Army.

Beat Zhang Lang away with a stick, and Zhang Dingguo ordered all his troops to attack on a rainy day.

In order to guard against the firearms of the volunteers, when attacking, they used a chariot or wet quilt in front, and they hid in the back one by one Onishi soldiers who were waiting for the day.

Firearms in this era were not very powerful, and although the projectile could shoot through two layers of quilt, the wet quilt could also resist the projectile at a distance.

Just like the concept of impulse in previous lives, impulse is the product of mass and velocity, and also the product of drag and time.

The car is a commonly used machine in ancient times, with four wheels underneath, and the car is blocked with thick wooden planks to cover the bow and arrow and lead bullet from the opponent's array.

Taking advantage of the windy weather, rain and snow, the Great Western Army used fences and wet quilts as cover to continuously press over.

Although the battalions of the Volunteer Army were equipped with grenadiers to throw improved versions of the earth-shaking thunder at the rogues behind the escape car and behind the wet quilt, and the sky-shaking thunder equipped with wooden handles could often throw more than 30 steps, the number of grenadiers in each battalion was relatively small (three groups in one brigade, and no more than twelve groups in one battalion), and the damage to the opponent was limited.

In addition, the bow and arrow are used to shoot from a distance, the crossbowman stands in front of the array at a 45-degree angle and shoots the crossbow into the sky, and the crossbow falls vertically under the action of gravity, killing and injuring the crowd hiding behind the fence and wet quilt.

However, the sky was cloudy and rainy, and it was difficult for the firearms of the volunteers to play a role, and the Great Western Army was not afraid of death under the supervision of Zhang Dingguo.

In order to resist the influence of the rainy day, the two combat brigades of the 7th Battalion relied on fortifications to defend on this day, and Feng Youqing personally led the two musket brigades to retreat into the woods.

In the face of such dense artillery fire, the Great Western Army suffered heavy casualties, and just when everyone felt that the overall situation had been decided, and it was completely possible to kill the enemy by retreating to the forest today, suddenly a little spark flashed in the distance.

It was autumn, the sky was crisp, the grass and trees were extremely flammable, and the sparks ignited the half-man-high weeds, forming a prairie fire for a while, and the whole situation was reversed.

In the face of the sudden change, Feng Youqing was stumbling, not only wanting to make the soldiers extinguish the fire, but also taking into account the swarming soldiers and horses of the Great Western Army, and finally lost his armor, was killed and retreated more than 200 meters, and was placed in the escort battalion to stabilize his position.

Looking at the grizzled Feng Youqing, when he heard the casualty report, more than a dozen people died in the fire, and more importantly, in the face of such a scene, the morale of the whole army was low, and some even urged them to wait for the weather to improve before concentrating on a battle.

Looking at Feng Youqing, who was at a loss, Yang Lin was annoyed in his heart, and his understanding of the limitations of the arquebus became clearer and clearer.

Due to the extensive use of open flames on the battlefield, arquebuses have historically become powder kegs on the battlefield, eating back against users.

In the Battle of Salhu, facing the Qing army in the wind and rain, the Ming army became a live target in order to set fire to the pine branches.

Now it is rainy again, and in the face of the rogue, everyone retreats to the forest, but because of the large use of open flames to ignite the surrounding weeds, resulting in local battlefield losses. (Historically, in the face of the Qing army's attack, the Southern Ming army also used a large number of arquebuses, but because of the ignition of the surrounding weeds caused a fire, and finally the Qing army was defeated)

Due to the continuous rain and the fact that the flintlock pistol had not yet been manufactured, Yang Lin was on the defensive.

After several days of fierce fighting between the two sides, the Great Western Army gradually took control of the first and second lines of defense, and its advance was now approaching the city walls.

After several days of study, Yang Lin concluded that in order to thwart the attack of the Great Western Army, it was necessary to use a large number of improved earth-shaking thunders.

Taking advantage of the rainy weather, Yang Lin urged all battalions and brigades to form grenadier teams, and urged the Ordnance Bureau to rush to produce 3,000 earth-shattering thunderbolts overnight.

In order to guard against the artillery and bird guns of the volunteers, the front of the team is a row of quilts or bamboo fences, because the firearm technology is not yet mature (mainly smoothbore guns, plus the proportion of gunpowder), the wet quilts and bamboo fences are like cotton armor, which can be used to prevent bird guns from attacking at a long distance.

In order to block the damage of scattered bullets and arrows from the Fran cannon falling from the sky, the elite soldiers wore cotton armor and iron armor, and the ordinary soldiers wrapped their heads in towels and quilts, and everyone hid behind wet quilts and struggled to move forward.

Behind the wet quilt and bamboo fence, there are rattan players, who hold high huge shields to block the lead and arrows in front of them, although there are wet quilts and bamboo fences to guard against them, but if there is more gunpowder, the wet quilt still cannot be covered.

The commander hid in the gap between the two quilts, observing the movement ahead.

According to the past custom, the most effective impact distance is 30 meters, and the soldiers holding wet quilts and bamboo fences in front of them will quickly throw away the shelter, and everyone will rush up to fight cautiously.

But this time it was a little strange, when I was more than 50 meters, I suddenly saw more than 100 soldiers rushing out of the opponent's formation, they were draped all over their bodies, some held burning pine branches, and some rushed out with baskets of bamboo baskets.

Du Du Wang Zhibang was shocked, pressed his hands down, and was about to make everyone stop, but the other party suddenly stopped more than twenty meters away, and then threw the ignited fireballs into the formation.

Seeing the earth-shattering thunder thrown into the formation, the soldiers of the Great Western Army in the formation were shocked, although there were earth-shaking thunders of the volunteers in the past, but they were sparse and scattered.

This time suddenly rushed out of a hundred people, and in the blink of an eye, hundreds of pieces were thrown, and for a while, the explosion sounded, and the entire front camp was shrouded in thick smoke, and the explosions were bursting, and the flames that burst out were wantonly devouring everything around.

As mentioned earlier, this earth-shattering thunder is different from the Tiger Squat Cannon, the Furlong Cannon, and the Redcoat Cannon, the Tiger Squat Cannon, the Franco Cannon, and the Redcoat Cannon have exploded in the barrel of the cannon and fell into the middle of the crowd, just relying on the original inertia to kill.

The Tiger Squat Cannon is different, the Tiger Squat Cannon is filled with black powder, and the outside is an iron shell, which is connected by a lead and falls to the destination, and the black powder inside is ignited and explodes, not only has a wave of air, but also blows up the iron shell, and kills and injures the opponent through the iron shell after the iron shell is exploded.

From this point of view, the explosion power of the earth-shattering thunder of the same gunpowder is several times that of the Tiger Squat Cannon.

In the sound of the explosion, the morale of the various brigades of the volunteer army in front was greatly boosted, and before the explosion stopped, everyone rushed over from behind one by one, rushed into the thick smoke, and saw the man who was not wearing a white sleeve and raised his knife and gun to slash indiscriminately.

The soldiers of the Great Western Army had seen such a battle, and they threw away their things and fled back with wet quilts and bamboo fences in their hands, and at the same time, Yao Zhijiao, Yang Bingyi, Jing Keqin, and Feng Youqing's battalions also led their troops to kill.

The state of the governor wanted to resist, but the surrounding soldiers panicked, everyone was in a mess, and they were unable to organize any effective resistance, and in the end they were surrounded by the volunteers, and after a fierce battle, they were captured on the spot.

Zhang Dingguo and Bai Wenxuan personally led the pro-army to help, and although they stabilized the formation after a fierce battle for half a day, the positions captured a few days ago were recovered by the volunteers in one fell swoop, and the two sides returned to the front line in the first battle.
