When the nest car was getting closer and closer to the city wall, and there was still a foot and a half foot, the grenadier lit the fire rope of the porcelain fire mine in his hand, and the captain next to him shouted: "Get down all down!" ”

The surrounding soldiers lay down one after another, the fire rope was burning rapidly, and the nest car was getting closer and closer to the city wall, one foot and two feet..... One zhang.... Eight Feet ......

Just when the nest car was eight feet away from the city wall, the fire rope of the porcelain fire thunder was also burned to the throwing red dot, the thrower roared, ran two steps, and struggled to throw the porcelain fire thunder out, the porcelain fire thunder drew a parabola, and accurately fell into the open above the nest car, and above the nest car stood a dozen strong Shatuo men, holding spears, they rushed out at the moment when they were waiting for the bridge to catch the city wall.

The porcelain fire thunder just hit the head of one of them, rolling down at his feet, and at the moment he landed, the porcelain fire thunder exploded violently, the fire light soared, the poison nails burst out, a soldier was swept up by the air wave, the surrounding wooden baffles were blown to pieces, and the top was suddenly exposed to the eyes of the Tang army, only to see more than a dozen soldiers fall on the wooden plank, covered in blood, some people died, some people were groaning in pain, and almost everyone was shot into hundreds of poisonous nails.

At this time, the thrower at the head of the city accurately threw the second porcelain fire mine into the staircase hole of the nest car, and the stairs inside were full of Shatuo soldiers who were ready to attack.

'Boom! The porcelain fire thunder exploded inside the nest car, and black smoke rushed out of the hole, and a terrible scream came out from inside.

"Throw the oil!"

Under the order of the captain, the soldiers quickly threw dozens of cans of fire oil on it, and the black viscous fire oil suddenly flowed all over the nest car, and a soldier threw the lit torch on the nest car, and the nest car immediately caught fire, and the fire spread rapidly, and the flames ran into the interior along the fire oil, and in just a moment, the nest car several feet high was suddenly engulfed in flames and smoke.

The same fate befell two other nest cars, three of which burned under the city walls.

But the attack of the Shatuo army continued, and one siege ladder after another set up the city walls, and the soldiers began to fight to climb the city.

At this moment, the trebuchet at the head of the city began to fire, and under a series of orders, thirty porcelain fire thunderbolts soared into the air and shot a hundred paces away from the city.

The porcelain vase fire thunder has been tested hundreds of times and is fully mature.

One by one, the huge porcelain vase fire thunder exploded above the heads of the soldiers of the Shatuo Army, making a loud noise - 'Bang! The shock wave it brought had little effect, but the thousands of quenched iron nails that burst out with the explosion were terrifying, and they shot densely in all directions, shooting through the leather shields, through the leather armor, into the bodies of the enemy soldiers, and the battlefield erupted into a scream of fear.

Although the distance of penetrating the leather shield and leather armor must be within thirty paces, more than 2,000 soldiers were still injured, especially when this firearm was used for the first time in war, and the fear it brought outweighed the firearm damage itself.

The soldiers shouted in terror, some of them turned around and fled for their lives, some of them were still at a loss for what to do, and some even knelt down to pray to the gods.

The Shatuo soldiers under the city were in a mess, but the trebuchet did not stop, the second round of trebuchets was launched, and thirty huge porcelain fire thunderbolts shot at the city, and once again exploded above the heads of the Shatuo soldiers, and a dazzling red flame suddenly appeared, like a devil suddenly descending, accompanied by black smoke, countless poisonous nails shot in all directions.

Large swaths of Shatuo soldiers were shot by poison nails, their leather armor and helmets could not stop the invasion of poison nails, and the severe pain and fear caused the soldiers to let out desperate screams.

The will to fight was finally shattered by fear, and countless soldiers shouted hysterically: "The devil is coming!" The devil is coming! ”

For a time, the army was defeated like a mountain, the Shatuo army shouted wildly, stumbled, and ran wildly without a life, the whole army fled in extreme fear, the Tang army took the opportunity to fire arrows in unison, and the running Shatuo soldiers fell to the ground with arrows.

Zhu Xie Jinhai was also stunned by the flames that suddenly appeared above the soldiers' heads, and when he saw that the situation was not good, he hurriedly ordered a retreat.

In the first attack, the casualties of the Shatuo army amounted to 5,000 people, of course, mainly injuries, arrow wounds and poison nails, especially poison nails, although the poison attack did not lead to death, but it made the soldiers feel painful, and they could only rely on their own physique to eliminate the toxins little by little, and lost their combat effectiveness for at least half a month, but in the eyes of the soldiers, they were cursed by the devil, and many soldiers died in fear.

Zhu Xie Jinhai was afraid of the porcelain fire thunder used by the Tang army, and he had the idea of retreating from the army.

After a failed attack, the Shatuo army temporarily stopped the attack on Dunhuang, and the fiasco of Zhangye a few years ago had taught the commander Zhu Xie Jinhai enough lessons that he did not dare to attack Dunhuang lightly, lest the enemy's new weapons would cause greater casualties.

But after Zhu Xie Jinhai got the report from the military doctor, he realized that it was not the devil who possessed him, but the Tang army used a new weapon, which was the same thing as the rocket that destroyed the speculative stone.

He suddenly regretted that he shouldn't have thrown away that particular crossbow arrow.

At this time, a soldier came to report, "Qi Ye Hu, there is an emergency military situation in Jinchang County!" ”

There are 500 Shatuo garrisons in Jinchang County, this news shocked Zhu Xie Jinhai, could it be that the Tang army began to attack Guazhou?

"Where's the emergency?"

The soldier handed over a roll of parchment, Zhu Xie Jinhai spread out the parchment and looked at it carefully, it was indeed an urgent military situation, and about thousands of Tang cavalry appeared on the east bank of the Styx River.

Shenshui is the boundary river between Guazhou and Suzhou, that is, the Tang army is ready to attack Guazhou, or rather, they are ready to support Shazhou.

At this time, a thought suddenly flashed in Zhu Xie Jinhai's mind, isn't this the battle merit sent by Immortal Heaven? It is no longer realistic to attack Dunhuang City, but he can't explain that he can withdraw his troops back to Shatuo, since thousands of Tang cavalry appeared on the grassland, doesn't this give Shatuo Army a rare opportunity?

At night, Zhu Xie Jinhai paced back and forth in the camp, repeatedly weighing the pros and cons, and he finally shifted the target of this expedition, that is, the thousands of Tang army reinforcements gathered on the border of Suzhou and Guazhou.

In order to prevent the prey from feeling the danger and fleeing back to Jiuquan City or Ganzhou, Zhu Xie Jinhai formulated the tactic of 'repairing the plank road in the open and Chen Cang in the dark'.

He secretly ordered the commander Zhu Xie Baozhen to lead 5,000 Shatuo cavalry to leave the camp at the third watch and rush to Suzhou unnoticed.

Zhu Xie Jinhai hated siege warfare very much, and he was eager to fight a decisive battle with the Tang army on the grassland, giving full play to the powerful cavalry combat ability of the Shatuo army, instead of jumping off the war horse, climbing the wall to fight, and using his own disadvantages to fight the Tang army.

Now that there is an opportunity to give full play to the advantages of Shatuo's cavalry in Suzhou, how can he easily let it go?

Suzhou, Yumen military fort, this is located in Suzhou and Guazhou junction of a fort, located on the side of Suzhou, there are 30 garrisons, in recent years, the Tang army and the Shatuo army are safe, the Shatuo army has not crossed the border to the south, the fort is basically safe.

But at this time, there were 8,000 Tang cavalry stationed next to the fort, which was less than 300 miles away from Shazhou, and if they received an urgent report for help, the cavalry would only need one day and one night to enter Shazhou.

The commander of the cavalry is Luo Daxiao, the envoy of soldiers and horses, he is also an old subordinate who has followed Guo Song for many years, a native of Fengtian County, Chang'an, more than thirty years old, tall and burly, with a thick beard, is the first batch of soldiers and horses appointed by Guo Song, ranking fourth, second only to Liang Wu, Yao Jin and Li Bing.

The soldiers and horses are actually generals, above the Zhonglang generals, according to the regulations of the Hexi Army, the Zhonglang generals can only bring 2,000 people from the headquarters, and the Lang generals can only bring 1,000 people from the headquarters, and only the soldiers and horses are not subject to the number of troops.

Although Luo Daxiao did not go alone like Yao Jin, nor did he follow Guo Song many times like Li Bing, but Luo Daxiao can stand alone, he has been guarding the Dadou Valley for a long time, Guo Song's evaluation of him is that he is both steady and cautious, but also good at improvising, this evaluation is very high, and it is precisely for this reason that Guo Song will give him the task of leading the army to support Shazhou.

The task is very arduous, not only to avoid a frontal battle with the main cavalry of Shatuo, but also to effectively rescue Shazhou, which depends on the wisdom of the commander.

Luo Daxiao firmly grasped the essence of the Fengzhou Army and the Hexi Army back then, that is, intelligence first, as long as he can grasp the enemy's movements at any time, then he can do both.

This is also the reason why he stationed his army in the Yumen Military Fort, the Yumen Military Fort has five letter eagles, the scout took the letter eagle to the front to explore the situation, put the letter eagle back, Luo Daxiao can grasp the situation in Shazhou and Guazhou at any time.

Early in the morning, a soldier from the fort rushed to Luo Daxiao's tent and said loudly: "General Luo, there is a red letterbox!" ”
