The "boom" earth-shattering loud sound with black-red fireballs soared into the sky, like a volcanic eruption, and billowing smoke accompanied by explosions rose into the sky, suppressing all the noise on the battlefield at once.

And the corpses of those Shatuo people who were in the center of the explosion were all over the field, and the severed arms and stumps flew in the air, and they were smashed to the ground far away, everyone was stunned at this moment, and even their own Tiance Army was stunned at this moment, and they forgot to wave the blade in their hands.

However, the Hellfire Brigade where Su He, the maker of these explosions, was not aware of stopping at all, taking advantage of this moment, the explosive package was launched as if it didn't need money, and only in an instant, the third wave of explosive bags appeared in the air again, and at this time, the second wave of explosive bags that landed also began to wreak havoc at this time, this kind of mushroom-like fireball rose into the air again, and the dense Shatuo soldier charging formation was finally torn apart at this moment, and the killing and fear brought by this epoch-making weapon began to spread with an explosion. The neighing of the war horses began to disobey the master's command, and the entire large array was completely disrupted by the war horses scurrying in private, and as the war horses lost control, the cavalry also began to commotion, and for a while, the forward of the Shatuo people even began to retreat.

The gunpowder of this era is not so much lethal to the cavalry, but rather this fear that penetrates into the heart of the warrior completely disturbs the hearts of the soldiers, and the reaction of the Shatuo army with all the cavalry is more obvious at this time, and the war horse is frightened and drives all the cavalry to start running aimlessly.

And Yang Tiancheng, who has been on the front line, roared fiercely at this moment, and at the same moment, the war drum team on the command platform of the Chinese army also came with the latest order, after the infantry brigade retreated, the Modao battalion on the front line began to show its hideous teeth, and only heard the snowy Modao knife in the hand of Shi Jian, who was covered in steel plate armor, suddenly raised high, with this action, the Modao battalion, which had been prepared for a long time, suddenly rushed forward, and the heavy steps began to sound, Five thousand people, lined up in two rows, the Modao battalion dragged the long Modao step by step, and appeared in front of the panicked Shatuo cavalry.

"Rise" The desolate and lonely Qin sound sounded, revealing the resonance of ancient time and space, and the snow-bright sword light suddenly appeared in front of the world's eyes, the knife array was like a forest, and the sword light reflected the snow.

"Fall" The same Qin sound sounded, shining with metal-like coldness and fortitude, the first row of five thousand Mo knife hands suddenly raised their hands, only to hear the sound of "puff puff" began to sound on the front line, and the huge heads fell to the ground between the swords and the swords, and the spurted blood instantly made the land fall into killing again.

After the first row of shots, he immediately flashed to the side, and the back row immediately grabbed it, and the two rows of Mo knife hands advanced alternately, and for a while, the head rolled down, and any obstacles in front of him were all cut off with a knife.

Seeing this, Yang Tiancheng immediately asked the retreating infantry brigade to form a group, and all the archers followed, so he stood behind the Modao battalion and bent his bow and arrows, and slowly advanced. The infantry turned into two wings with the Modao battalion as the arrow, and a huge sharp arrow formation was completed in an instant, and began to rush against the Shatuo cavalry.

At this time, Li Siyuan, who was behind the Shatuo array, also reacted from the shock, and began to try his best to mobilize all the reserves to come forward, wanting to block the edge of the Modao Battalion, and the scene became even more chaotic for a while. This also gave Su He's Hellfire Brigade more opportunities to show, the dense crowd made these messengers from hell do not need any aim at all, the explosive bag frantically rushed towards the crowded place, almost every explosive bag brought boundless bloody rain, the tearing caused by the explosion made the Shatuo cavalry near the explosion point have no way to dodge, this kind of panic caused by brute force over time and the continuous loud noise made the Shatuo cavalry more impatient, and more frightened, and could no longer organize any formation, Li Siyuan completely lost control of the army.

"War drum team, send a message to the guard battalion, and give me a direct entry into the Chinese army of the Shatuo people. Su He, immediately set off smoke rockets, summoned the party cavalry battalion, and the whole army assaulted. Xu Tianxiang almost roared at the command platform.

"The soldiers of the Tiance Army, pluck up the courage and assault the whole army, and the victory or defeat is in one fell swoop. In the first battle, we played the momentum of the Tang Dynasty army and the majesty of the Tiance army. God bless the Tang Dynasty, and the Han army is mighty. Li Xuanqing, who was on the viewing platform, suddenly used his internal force, and his clear words spread far away from the battlefield like the Nine Heavens Divine Thunder, which also added the strongest dose of blood to this war.

Almost as soon as Li Xuanqing's words fell, all the soldiers of the Tiance Army suddenly burst out with a tsunami-like shout: "God bless the Tang Dynasty, the Han army is mighty." "The encouragement from the supreme commander made the blades and guns cut out by these soldiers more powerful than before, and the morale was like explosives that continued to explode, permeating all the locations of the Tiance army, all the soldiers were indomitable, desperately rushing forward, and even the infantry who had arranged those small bomb-throwing devices arranged by Su He in the infantry brigade to ambush Li Cunxiao rushed directly into the crowd with explosives bags, and then lit the explosives bags and threw them directly, some of them were not even willing to throw them, Directly connected with people with explosives bags exploded in the Shatuo cavalry.

The war has reached this level, and the Tiance army has relied on explosives bags to counterattack to build morale and military prestige. The area where the Modao battalion is located is full of blood, the heads are like mountains, the corpses of war horses are everywhere, and there is no opponent at all wherever the sword light array advanced like a wall goes, and the blade and arrow array has been invincible since it began to take shape, and it is forced to rely on the infantry to beat the Shatuo people back and forth.

"Si Yuan, immediately organize the people to evacuate quickly." When Li Siyuan was hoarse and mobilized the army to try to block the pace of the Tiance army's attack, Zhou Dewei also found Li Siyuan, grabbed him and shouted.

Zhou Dewei's words seemed to have also sobered up Li Siyuan, but wouldn't retreating at this time declare his attack on the Tiance Army a complete failure? The cavalry corps of 100,000 people was defeated by tens of thousands of infantry on the opposite side, how could this young and vigorous general Shatuo swallow this breath? So almost at this moment, Li Siyuan pushed Zhou Dewei away and roared angrily: "Wouldn't retreating at this time be a waste of all your efforts? No, you will never retreat, you will immediately transfer all 20,000 men of the rear army and attack from the flank, and you must beat the Tiance army back. ”

Zhou Dewei looked at Li Siyuan, who was almost in a frenzy, sighed silently, hesitated a few times but couldn't make a move, so he could only turn around.

Although the Shatuo cavalry was defeated and retreated, the reinforcements behind were coming in a steady stream, the front retreated, the back advanced, the Shatuo people were completely chaotic, their own people formed a huge bloated part on the battlefield, and the people on both sides were concentrating towards this area, this kind of chaos is no longer something that manpower can reverse in a short time. And with the advance of the Tiance Army step by step, this chaos is becoming more and more obvious, and the explosives package caught in the chaos has become the largest weapon of destruction, and this increasingly dense crowd gives the best room to exert itself, and almost every explosion will take away more than a dozen lives. Su He even ordered half of the ballista troops to begin to move with the infantry, ready to follow up with the projection. This method of migration with the army also prompted a new round of improvement of ballistas after the war, a ballista that can move with the infantry beyond the times was designed, and this kind of ballista that can be moved by the car crossbow will accompany the Tiance Army in the future with the southern and northern wars, and also laid the foundation of a new type of troops - the early birth of artillery.

At this time, more than ten miles away from the rear of the Shatuo people, a huge cavalry army accompanied by a huge amount of smoke and dust in the gallop, straight towards the rear army of the Shatuo people. The cavalry on horseback was the party cavalry and the battalion directly under the Tiance Army uniform.

"Tell the brothers, speed up, the striker is a hundred paces away from the opponent and immediately prepare to ride and shoot, the brothers of the infantry army have already fought very hard, now we will go to the final word, take revenge, in one move." The leading Tuoba Siji roared at the heralds beside him as he galloped on horseback.

Although the arrival of the Dangxiang cavalry was huge, the scouts of the Shatuo people were almost unnoticed, and the Zhou Dewei Corps, which was originally arranged in the rear army, had been transferred to the front line at this moment, and the entire rear army of the Shatuo people was left with only the men and horses withdrawn from the battlefield and some other auxiliary troops, and the troops of less than 20,000 people could only watch the Dangxiang soldiers pressing the border but there was no way to meet them.

And Zhou Dewei, who had just arrived from the front army, saw the smoke and dust in the distance, his face suddenly turned pale, and his body began to shake, if it wasn't for the guards around him who hurriedly stepped forward to support him, he would have even fallen off his horse.

"General, let's get out of here." The guards around him hurriedly said after supporting Zhou Dewei, and at the same time began to form a circle and guard Zhou Dewei in it.

"Withdraw, how to withdraw, people have already laid an ambush and waited for us to withdraw. Besides, how can we withdraw now that we have no soldiers? Zhou Dewei smiled bitterly. The cavalry arranged by Li Xuanqing was actually easy to guess. Even he and Li Siyuan knew that the other party had a cavalry in his hand and did not appear on the battlefield. The difference is that Li Siyuan's idea is that Li Xuanqing will use this cavalry as the main force when the battle situation is unfavorable, disrupt his deployment by raising troops and counter-charge, hold the central formation with infantry, and assault the flanks with cavalry.

In fact, looking at Li Xuanqing's previous method of using troops, Li Siyuan's idea was right, and he basically continued the previous practice, but Li Siyuan did not expect that the other party would directly let the cavalry sneak attack from behind. If the other side has a way to arrange this method in advance, the diversion effect is not as fast as attacking from the flank. Moreover, this is obviously to have full confidence in the ability of one's own infantry, which is a bet that one's own infantry can independently support the battlefield and play the role of the main force. Where did he get his confidence? Is it because of those strange weapons that can explode?

Zhou Dewei hurriedly went to find Li Siyuan, but he didn't see that the main force of the front army was the nemesis of light cavalry like the Modao Battalion. However, this did not affect his guess of Li Xuanqing's method of using troops, which obviously included the psychology of his own coach, and the temple was almost leakless.

"General, let's go and join General An, and then retreat north to Hezhong Mansion, as long as Hezhong Mansion is kept, then everything has room for redemption." Zhou Dewei was stunned, and the chief of the guard beside him hurriedly said.

Zhou Dewei was also awakened by this roar, and reacted instantly, he couldn't take care of Li Siyuan on the front line anymore, in addition to sending someone to inform him, he hurriedly took his personal guards and hundreds of people along the way to the northwest corner to rest and recuperate.

"General An, immediately order the troops to leave immediately, return to the army in Hezhong Mansion and join the second general." Zhou Dewei didn't even have time to explain anything to An Xiuxiu, pointed to the clear figure of the party cavalry in the smoke and dust raised behind him, and said quickly.

An Xiuxiu also discovered the abnormality of the battlefield at this time, but because Li Cunxiao was not there, he did not have much right to speak, so he just secretly put his troops on guard. At this time, seeing Zhou Dewei speak, he immediately understood what he meant, and without hesitation, with a wave of his right hand, all the cavalry instantly turned their horses and galloped in the direction of Hezhong Mansion.

His departure also announced that the rear army of the Shatuo army was completely exposed in front of the party members, and this kind of rear army, which was not even fortified, had no way to stop the horses' hooves of the party members, galloped past, and headed towards Li Siyuan's back.

"General, the big thing is not good, the party people sneak attack the rear army, and General Zhou urgently asks for help." When the horseshoe of the party people stepped on the rear army, the flying cavalry sent by Zhou Dewei also found Li Siyuan at this time and reported the fatal news.

Li Siyuan was stunned by this news, and at this moment, even everything around him blurred in front of him. The rear army was attacked by a sneak attack, and it was impossible to block the other party's fatal blow with Zhou Dewei's troops, and he was defeated. After a while, Li Siyuan shook his body, and suddenly a mouthful of blood spurted out, his eyes were dark, he couldn't support himself anymore, and fell headlong.

"General, General." Li Siyuan's fall to the ground made the surrounding guards chaotic, and they hurriedly helped Li Siyuan up.

"Quick, get out." Li Siyuan struggled, and after saying this, his head tilted, and he fainted again.
