Before the war, Cao Yue planted a large amount of explosives, estimated at several thousand catties, at a distance of about 700 to 1,200 meters in front of the carefully built field position. If Jiannu wants to kill the position of the Ming army, he must rush to this area, and Cao Yue is ready to use these thousands of catties of explosives to meet Jiannu, who is fortunate enough to rush through the artillery firing area, he calls this move "hellfire".

Because the trigger fuse has not yet been developed, Cao Yue has no energy to personally do technical research and support, so he can only use the primitive method of using artillery bombardment to ignite the explosives buried in the ground.

This was not much difficulty, the explosives planted in both directions were detonated almost at the same time, like an earthquake explosion, two small mushroom clouds rose into the sky, and just rushed to the explosion area of the Jiannu people and horses, a large area was torn apart by the violent explosion, countless people and horses, were blown into pieces, mixed with each other, and a piece of mud that was blasted into the sky, flew for a while, and fell back to the ground, no longer able to distinguish between you and me.

Bo Hezhen, who was bent on avenging Bolo, as well as most of the hundreds of personal soldiers around him, and one of the thousands of soldiers in the Zhenglan Banner, all disappeared in this huge explosion, and the bones could not be found. The two brothers were mixed with the land of the Ming Dynasty in this way.

Seeing such a violent explosion and the black smoke and fire that rushed up, Gao Jie, Huang Degong, Liu Liangzuo and others, who felt the strong shock, were so shocked that they even dropped the telescope in their hands, and the telescope fell, and was tied by the rope hanging around their necks, and it reverberated and smashed heavily on their stomachs, and they didn't notice it.

They didn't know Cao Yue's plan, but they didn't expect that in front of the defensive position, Cao Yue had already planted so many explosives, and it worked wonders, at least blowing up thousands of Jiannu into the sky.

The explosion in both directions had a wide range, and Jiannu just rushed to this area, and the killing effect of the explosion was amazing. Not only thousands of slaves were devoured. Moreover, the place was blown out of the huge crater, and even if the subsequent Jiannu rushed forward without their lives, this huge crater would become a huge barrier to their progress.

These people who followed Cao Yue to watch the battle were deeply shocked. Although this huge explosion caught them off guard, they were so frightened that they were almost shocked under the lookout, but there was only one thought in their hearts now, that is, Cao Yue's arrangement in terms of war was too different from ordinary people, the youngest commander in the history of the Ming Dynasty, and the war strategy pursued. They never even thought about it. The arrangement of artillery can receive miraculous results, and now there is such a move, when Jiannu suffered heavy losses, the Ming army still had almost zero casualties, such a war, they have never experienced it. Any one of them, the admiration for Cao Yue can be described as a surging flood and endless.

In the minds of Gao Jie, Huang Degong, Liu Liangzuo and others. War is nothing more than the fight between the two armies, the difference is whether there is the cover of the city wall, or the difference between the two sides, the strength of the morale and combat effectiveness of the two armies. But I didn't expect it. Cao Yue had a strategy that they had never dreamed of, and on the premise that he had not suffered any losses, he had severely damaged Jiannu several times.

They used to think that Jiannu's combat effectiveness was super strong. Almost invincible, Jiannu's cavalry and archery level can only make the Han people unreachable. And their homicidal nature. It is also something that the moderate Han people do not have. But today, their views have been completely turned upside down. The war we see now is a completely asymmetrical slaughter. Jiannu even had the opportunity to rush to the front of the Ming army, and the charging Jiannu sergeants suffered extremely heavy losses under the slaughter of artillery and explosives. They even felt a little sorry for the slaves, their fate was too tragic.

"It turns out that the battle can be fought like this, and gunpowder and firearms have such lethality," whether it is Gao Jie, Huang Degong, or Liu Liangzuo, they seem to wake up from a dream and have a new understanding. "This is a naked massacre!"

They now truly understand the tremendous lethality of gunpowder and firearms, which cannot be compared with bows and arrows, knives and guns. They only now know how Cao Yue could be so confident, with an army of 80,000 horses, he dared to fight against 200,000 or 300,000 Jiannu in the field.

This kind of tactics was completely unimaginable in the past, and the Ming army relied on the strong city, and there was no way to block the attack of the slaves. They also fully understood what method Cao Yue used to defeat the Jiannu army in the defense of Datong. It's just that they don't understand, Dolgon didn't suffer several losses under Cao Yue, why didn't they come up with a way to deal with it, and still attacked in the old way?

Earth-shattering explosions in both directions and huge clouds of smoke also alarmed Dorgon.

Encountering the fire of Ming artillery and muskets during the Qing army's desperate assault, Dolgon was anticipatory, and he was ready to accept the fact that he suffered heavy losses. He just hoped that he could rely on the attack of not taking, rush to the front of the Ming army, kill the Ming army, and finally shake the defensive position of the Ming army. Dolgon knew that most of the Ming army led by Cao Yue were newly recruited recruits, and they were trained for up to half a year. These recruits were poorly trained, let alone experienced war and killing, and as long as the Qing army broke through their musket defenses and killed them, perhaps these recruits would be in disarray and could flee immediately.

But he never dreamed that Cao Yue still had several tricks. Dozens of hidden artillery pieces with a long range killed many young people in a few rounds of bombardment, and even his favorite general Bolo was killed. Then there was the more intensive shelling, the number of artillery pieces so large that he and his advisers could not estimate the explosion, and finally the explosion of such a large scale. Dolgon didn't know what means Cao Yue used to create such a huge explosion, but he knew that the huge explosion of similar scale in two directions, the Qing army, which rushed forward desperately, must have suffered heavy losses.

Bo and the subordinates rushed to the forefront, and Abatai's beloved son might encounter another accident.

Abatai left his two sons in his care, and if something happened to both of them, Rao Dolgon would have no shame to face him and his brother no matter how powerful he was. He hurriedly ordered Bo and Yu to retreat and suspend the attack.

Dolgon knew that even if Bo and Tsu were still alive, this wave of attacks on the Qing army was defeated again.

Under such huge losses, the charging Qing soldiers must have been frightened, and the rout was inevitable, even if they could get lucky enough to rush to the front of the Ming army, maybe Cao Yue would have some tricks. He had to change his tactics and no longer attack in such a simple way. Such an attack, even at a heavy cost, would not necessarily defeat the Ming army.

Before today, Dolgon's greatest fear was the Ming army's musket array, but now the Ming army's musket array has not yet exerted its power, and the Qing army has suffered heavy losses. From the sound of the explosion, Dolgon could deduce that the Ming army must now have more musket equipment than before, and the power of each wave of shooting is also greater, and the Qing soldiers who escaped the artillery bombardment can rush to the front of the Ming army, and they must also be shot by the musketeers.

Therefore, he decisively gave the order to temporarily stop the attack and retreat on all fronts. (To be continued.) )
