Simple gas and biogas will not explode, but after fully mixed with air, there are conditions for explosion, when the blower fills the air bag with gas, it naturally brings a lot of air into it, and now encounters an open flame, the air bag that has already had the conditions for explosion has an earth-shattering explosion, the shock wave crashes into the ground at a speed of hundreds of kilometers per second, tearing the iron bracket and wooden board into countless pieces, driving a large number of fierce fire oil cans and thistles buried underground to fly into the sky, followed by raging flames, The fierce fire burst out of the ground like a volcanic eruption, sweeping through all living beings on the ground.

The tall city walls of Yanzhou trembled, the houses in the city also trembled, the tiles flew wildly, some thin grass houses simply collapsed directly, all the residents were temporarily deaf by the violent explosion, and the brain was confused for half a day before recovering hearing, chickens, ducks, pigs and dogs were even more strongly frightened, for a time adults and children cried in horror, and the mournful barking of the watchdogs resounded throughout Yanzhou.

The soldiers of the Ming army on the city wall were stunned by the sudden explosion, the Tianzi plan is a military secret, most people know that the explosion occurred, with an indescribable huge explosion, the soldiers who have not been stunned saw that the open space under the city full of enemy troops is gone, and there seems to be thousands of hellish devils emerging from the ground, with fire and debris throwing everything on the ground high, broken weapons, the wreckage of people and horses, carriages, flags, and more mud and flames, thrown hundreds of feet high by the shock wave, There was smoke and fire for several miles, and it was a hell of a nose. The unknown soldiers were so frightened by the inexplicable fear that their teeth chattered, and the two trembled.

The two battalions of the east and west, which were ten miles away, were also stunned by the explosion, and the horses went berserk, stepping on their hooves and neighing incessantly. The soldiers first heard a violent explosion and felt the earth tremble, and then a hot wind blew, and the fire in the direction of Yanzhou City in the distance went straight into the sky. The soldier standing on the lookout used a clairvoyant mirror to see that the banner on Yanzhou City had not fallen, and shouted happily: "It's a Tartar!" The Tartars were blown up. "There was thunder in the camp, and such a violent explosion must have killed and injured countless Tartar soldiers, and this is a relief for hatred.

Yuan Chonghuan was also stunned by the devil he summoned, he didn't know that the power of the airbag explosion was so great, I was afraid that fish could be raised outside the north gate of Yanzhou in the future, outside the north gate was full of smoke and dust, and there was fire everywhere, and it seemed that there was no need to even send cavalry to take advantage of the fire to rob.

The shock wave from the explosion lifted tens of thousands of cubic meters of dust into the sky, and then fell again, and even the people on the city walls were covered with a layer of dust, and the soldiers on both sides of the battle were stunned, looking at this unbelievable scene together, and even forgetting to fight.

Liu Ziguang was also stunned, he didn't expect the power of the gas explosion to be so strong, and it was not much compared to explosives, but he was a person who had seen a big scene, this kind of explosion was still worse than the explosion scene in the movie after all, and the Qing soldiers who were fighting on the opposite side did not have such a high psychological quality, and the steel knife in his hand fell to the ground in shock, and Liu Ziguang, who was the first to wake up, was hacked to death with a knife, plus a kick, and kicked down the city. The surrounding Ming troops also came to their senses, and a burst of slashing drove the demoralized Qing army off the city.

With the explosion heart as the center of the circle, a radius of one mile has become a real hell on earth, first a strong shock wave threw everything on the surface into the air, and then a large amount of fierce fire oil and thistle terrestris smashed in all directions with the shock wave, and the centaurs who were slightly closer to the explosion heart were turned over by the people who were slapped by the air waves, and avoided the iron thistle terrestris that followed, and the people and horses farther away were not so lucky, and they were pierced with blood holes by the high-speed flying thistles, and the corpses were all over the ground immediately. Behind the shock wave was a gas fire that burned rapidly, and the pervasive flames ignited the fierce fire oil and all flammable things scattered everywhere: flags, wooden vehicles, and even the clothes on their bodies, the Qing army, which was lucky not to be lost in the shock wave just now, was now in a sea of fire, the sky was full of smoke and dust, the visibility was less than a kilometer, and all that could be seen was minced flesh and the bleeding and delirious comrades who were shocked.

The vast majority of the undead Qing soldiers had fallen into a collapse, their eardrums had burst, they couldn't hear sounds, and they were all walking corpse-like horrors in their sight, and the strong stimulus prompted them to go berserk, closing their eyes and waving their weapons to kill indiscriminately, as if only by killing any moving object around them could they suppress the boundless fear in their hearts.

The fear comes from the unknown, and the other Qing army troops who are far away from the heart of the explosion are also scared silly, the dust and dirt mixed with flesh and blood smashed on their heads, and they don't know how to dodge one by one, this is definitely not the weapon of the Ming army, it is the Lord of Yama who is angry, the sky is falling apart, I don't know who screamed miserably first: "Run, it's going to explode again!" Then the weak-willed Han Eight Banner troops dispersed in a hurry, and no one was sure that there would be a first time or a second time, and maybe the next explosion would happen at their feet at any time. It's better to run, the farther you go, the better.

The weak-willed green battalion soldiers did not run, because their feet were frightened, and the neatly arranged ranks stood in a daze, until hundreds of frightened white flag war horses rushed over in front of them before they broke apart, and for a time people shouted and neighed, and everyone ran around like headless flies, and they knew that they were running backwards, and they could only scatter and flee in all directions, although there was fire everywhere, but the visibility was still very poor, and the Qing soldiers trampled on each other, and the dead were countless.

Ao Bai commanded the battle in the city, so he escaped a catastrophe, experienced in a hundred battles, his heart was like steel, he couldn't believe everything in front of him, the position he was standing in just now had turned into a deep pit, the apricot umbrella cover was nowhere to be found, and the life and death of Rui Wang Ye and Sonny were uncertain. The warriors around him were all disgraced, looking behind them blankly, this defeat was defeated, Aobai's heart was dripping blood, and the victory was in hand, but it was defeated for no reason, it was really unwilling, does God really want to destroy my Qing Dynasty? Now is not the time to complain, retreat quickly, there are still tens of thousands of horses in the camp, and it is the right topic to pack up the remnants of the army to avoid a rout on the whole front.

"Withdraw!" With Aobai's order, the siege troops threw down the ladders and various siege vehicles, and fled into the smoke and dust quickly. The place where Dolgon beat the drum was on the verge of bursting the heart, with a heavy cart as cover, fortunately not thrown into the sky by the shock wave, but pushed far away by the air wave, the huge war drum was full of thistles, which became the shield of the Rui Wangye, he woke up after a little coma, struggled to stand up, shook off the dust on the armor, saw that the entire Qing army's battle line had collapsed, and couldn't help but spurt out a mouthful of blood, just now was shocked out of internal injuries. Ao Bai, who retreated in a hurry, found him, and hurriedly ordered two soldiers to support the prince and quickly retreat in the direction of the camp.

Dolgon's big silk and apricot yellow umbrella cover have disappeared, and Sony, who is sitting in the Chinese army, has also blown up the bones and bones, and there is no big banner to be seen, no officers can be found, and the entire Yanzhou city is in chaos, although the Qing army directly killed by the explosion is no more than a thousand, but the indirect death is countless. The troops sent out today are all gone, and they can't be counted on for a while, and now they can only rely on the tens of thousands of armored men stationed in the big camp.

The Ming army at the head of the city was unwilling to give up this opportunity to add fuel to the fire, and the steam repeater raised the firing angle to the highest, and scattered the shots towards the figures of the demons dancing in the smoke and dust, intending to create more chaos and casualties.

"Dashuai, let's take advantage of the chaos to get out!" The deputy general He Kegang was eager to try, "Dashuai, let us kill it." The generals also followed suit.

"The generals will obey!" Yuan Chonghuan shouted, his eyebrows flashing with joy that could not be hidden

"The last general will obey the order!" All the generals shouted in unison, and they all stood in a line, and Liu Ziguang was also among them, standing next to Wu Sangui.

"Man Gui, Zu Dashou, you two go back to the base camp, lead the people of the headquarters to smash the nest of the Qing army, sweep the nest of the Tartars, and drive them back to their hometown.

"Order!" The two of them could not personally command the troops, they were already so anxious that they stomped their feet, and now that they had received the general's order, they happily took the generals of their headquarters down to the city.

"What a gang! Ben Shuai ordered you to lead 30,000 horses out of the north gate to annihilate the defeated Qing army outside Yanzhou City. ”

"Zhao rate teaching! Ben Shuai ordered you to lead 10,000 horses to attack Tai'an and cut off the retreat of the Qing army. ”

The second general went to the command, and was pressed and beaten by the Tartars for more than a month, and he was finally able to raise his eyebrows.

"General Liu, please also lead the cavalry of your headquarters to track down the whereabouts of Dolgon in the chaotic army, if you let this old thief escape back to Beijing, you may be able to accumulate men and horses to fight against my Ming Northern Expedition, such an important task, you still have to worry about brave generals like you." Yuan Chonghuan said to Liu Ziguang in a different tone of discussion.

The generals were surprised, what kind of important task is this, it is very simple, it is enough to send a small colonel, and then everyone woke up again, the marshal wants to give this great credit to the general, to repay the grace of saving his life, Liu Ziguang not only saved Yuan Chonghuan's life, but also saved them, this kindness should be repaid!

There was a smell of burnt skin and flesh in the air, and the smoke and dust outside the city had dispersed, but the fire continued, and the Qing army had scattered and fled, leaving only dozens of trance-like Qing soldiers still wildly waving knives on the battlefield.

The north gate of Yanzhou, which had been closed for a long time, suddenly opened, and the 30,000 Ming army roared out and chased after the Qing army like a whirlwind and clouds.

Man Gui and Zu Dashou also hurried back to their respective camps, picked up the men and horses, poured out the nest, and went straight to the Qing army camp. At the moment, the Qing army cannot be given any respite, and it is necessary to strike while the iron is hot and fight a beautiful battle of annihilation.
