The firecrackers of the Tang Dynasty were really firecrackers.

That is, some flammable powders are stuffed into the bamboo tube, such as sulfur and nitrogen, and dragged them outside with a fuse rope, and lit them when used, ignite the sulfur and saltpeter inside, so that the burning bamboo tube will emit a violent explosion.

When Xifan was placing troops and scrutinizing, in addition to beating drums, firecrackers would also be blown up.

At night, Xifan scouts who went out to patrol also carried a bunch of firecrackers on their bodies. When they noticed that there was an enemy situation, they used this object to warn the city.

"What's going on?" The soldiers on the top of the city stood up in surprise, and saw that there were constant lights of firecrackers bursting in the darkness about two or three miles below the city, which made people extremely nervous.

Then a pair of bonfires suddenly lit up there, and several cavalrymen passed by in the fire, running towards the gate of the Sand Castle, shouting:

"With Tang soldiers attacking, the escort team that had passed Xiaoguan and Baicaoyu had been ambushed by them!"

"What!" Soon, the head of the sand castle was knocked on the police drum beats quickly, and the sound of trumpets was mixed with the sound of trumpets. On the city wall, some soldiers opened their bows and arrows, while others stood between the marches to protect the archer's "turning shot". The so-called arching shot wood is to tie the log into a "gong" shape, and the outer Mongolian cowhide can guard against enemy arrows. A circular hole was chiseled in the middle of the arching shot wood to set up a strong crossbow and for the archer to observe. There is a rotation axis below, which allows them to pitch and rotate. In short, it is similar to the shield of the machine gun behind it.

Fires were lit in the city, and warning sounds were everywhere. Even the ambassador of Fangcheng Hu Qulusimeng was startled from his sleep and immediately began to wear them to find weapons.

He was still confused and couldn't believe it, "Where did Tang Bing get out?"

Then, under the city of the sand castle, more than a hundred cavalry wearing Western-French soldiers appeared. While running, they shouted to the people on the fortress, "We are all from Baicaoyu in Bairi, hurry up, the Tang soldiers behind us come here, let us enter the city!"

There were also several old Changwu soldiers, riding horses and throwing their weapons. They looked up and shouted to the city that was in a hurry: "Wang Yuhou (Chaogan), Da Xi army envoy (Xiaojun), we are so-and-so! Let us in quickly, Tang soldiers rushed over behind them, all of them were white helmets and white armor, wearing Empress Zhaode's filial piety!"

These words aroused the panic of the sand castle guards. Soon at the northeast corner of the city, several guard soldiers stood under the battle shed with horse-faced walls, pointed to the mountain opposite, and shouted suddenly: "The Tang soldiers with white helmets and white armor are here!"

People followed the shouts and looked at each other from behind.

On the vague barren mountain, only the sound of horse hooves like wind and thunder could be heard, and then a large black shadow seemed to be moving quickly.

But in a short while, the clouds were dispersed by the strong wind, and the cold moonlight shone again on the Hulu River in the gap between the high clouds. A stream of Chengjiang lies like white, making the hills opposite the sand castle clear and bright. At this time, the top of the sand castle burst into screams:

Really, there were thousands of Tang army cavalry covering the entire hill, chasing their own people, and the armor and helmets of the Tang soldiers were really tied with white zither, blowing on the armor and blades with the wind, rolling towards the sand castle like frost falling to the ground.

"Hey..." At this time, at the east gate of the sand castle, the soldiers guarding the city were pulling the wheels and slowly lowering the originally hung gate, preparing to support the "defeated soldiers" from Baicaoyu to enter the city.

At this moment, Hu Qulu Ximeng had just walked out of Zicheng's yamen and wanted to ride a horse to the east gate to observe the situation. As a result, he received a report from his subordinates. Thunder was furious and rushed to whip the horse to stop it. "The authenticity on the battlefield is mixed, how can you easily let the defeated soldiers enter the city?"

Before he finished speaking, a huge sound of killing suddenly broke out in the curved wall of the wall of the east gate of the sand castle:

The "defeated soldiers" who were just put into the city suddenly revealed their true colors.

Ming Huaiyi, who disguised himself as a foreign soldier (he did not dare to pretend to be a leopard skin general this time, because the generals in the sand castle were familiar with each other and could not disguise him) drew his sword first, and slashed the two guards at the city gate corridor like lightning. Just as the other person was about to run away, Ming Weiyi stepped forward, raised his long spear, and stabbed the other party to death on the edge of the forks in the corridor. The blades of the spears were several inches into the wooden stake before they were pulled out.

"Fake, fake!" Soon, Ming Huaiyi heard the sound of explosion on the city tower.

Then the city gate suspension bridge creaked and was slowly pulled up again.

"Brother!" Ming Jingyi pointed to the inner door leading to the heavy wall in the urn city. Several soldiers from the city pushed it away and prepared to cover it again.

"Jing Yi followed me to rush over, seized the inner gate, and rushed in - Wei Yi, you cut off the iron cable from the outer gate and helped the army enter the city!" After Ming Huaiyi shouted, he flew onto a horse with his brother Jing Yi, and more than a dozen of his sisters, the personal soldiers of Dangxiang, drove the war horses to neigh in front of the inner gate of the urn city, and rushed in from the cracks between the city gates.

"Kill, kill." Then the two brothers Ming Huaiyi immediately clamped the city gate tightly, swung their swords and slashed left and right, and refused to let them close together.

The soldiers of Xifan rushed up, three-pointed horns, long snails, flying arrows, and blades greeted them like raindrops. Soon Ming Huaiyi's chopping turned into blocking, and he was struggling. Fortunately, the chain mail was seized from Xifan, and he was extremely tough. He was not injured after fighting to the death!

Soon, reinforcements arrived, and the Changwu army soldiers who were anyway burned everywhere and shouted, "The Changwu army is anyway, and they are leading the heavenly soldiers to climb into the city from the northwest side!"

The sand castle was in chaos. The Changwu Army, who had just left the camp, met the foreign soldiers who were mistaken for false information. Without saying a word, they fought and killed each other.

At the outer city gate, Ming Weiyi and several white grass soldiers wearing heavy armor swung their sharp axes and cut off the iron cable of the rumbling suspension bridge of the city gate. The suspension bridge fell to the moat with a bang.

On the hill opposite the sand castle, under the black and white Pixiu flag, Gao Yue was wearing armor and riding on a horse, commanding - no, the Baicao Army soldiers and horses that supervised Gao Gu, commanding various troops and horses, and rushed in along the east gate that had already succeeded.

Soon, the sand castle that was attacked by night was panicked and fell apart. The military system of Xifan was divided into three types. One was Zanpu's Imperial Guard, which was drawn from the tribes and had the strongest combat power; the second was to belong to the "Border Army" composed of inferior warriors from each tribe. Shang Jiezan and Ma Chongying's troops were of this kind, and the combat power was also very strong; the third was that the so-called city defense army had a complex source of troops, and there were lack of war horses. Because the cavalry basically went to the imperial guards and border troops, the combat power was the weakest among the three, and it was not the opponent of thousands of elite cavalry of the Tang army.

Gao Yue’s attack is the weakest, that is, what is said in the art of war to force weakness and avoid the real and attack the virtual.

At dawn, the Tang army had already opened the inner and outer city gates from the east, and bravely seized most of the watchtowers and corner towers, drove away high to suppress the foreign soldiers, and set fire everywhere, and flames filled the entire sand castle. The British soldiers, Qiang soldiers, and the rebels of the old Changwu Army had to open the west gate and began to flee along the mountain road to the pass behind.
