On the fourth watch, Ma Dingde, who had completely negotiated the conditions with the infiltrated Langxi, climbed to the head of Liuqiang Town, raised torches, lit three piles of reeds, hung the frog flag, and the beacon flames suddenly rushed up, illuminating the night sky that was still black.

Soon, at the gate of Liuqiang Town, and all the Xifan forts and camps shouted and killed, and the defense envoy of the city of Gong, Dongchai, bravely rode his horse first, and led five thousand elite soldiers to swarm out and kill the east wall of Zhucheng.

At the same time, on the high platform of Saigon River, nearly 10,000 Xifan soldiers from Saigon and Lacheng also rode out on foot, wading across the river, and launched an attack on the western wall of Zhucheng.

In the city, Ma Dingde pretended to swing his saber and commanded his subordinates to pull the rope behind the wall, so that the seven-tip cannon and the five-tip cannon shot dense stones at the Dingwu military camp outside the city, in order to show the effect of "containment".

At this moment, in Zhucheng, the Tang soldiers and the Eastern Barbarian soldiers were already ready for battle, and they waited for Xifan to throw themselves into the net:

Xu Qi, Lu Pang, and Tho each commanded the Eastern Barbarians at that time, and lined up with spears in the center of Zhucheng;

Cai Fengyuan led two battalions of chariots and men and lined up behind the bamboo fence of the west wall;

Guo Zaizhen led a battalion of chariots and men and lined up behind the bamboo fence on the east wall.

"According to the artifact song, the hairbolt!" Guo Zaizhen, who tilted his neck slightly, looked at the bamboo fence, and the various departments of Nondongchai who came from the slope of Liuqiang Town like a storm rode in front of the bamboo fence, waved the flag and ordered loudly.

Nearly 800 Dingwu military vehicles are in charge, sub-station three times, the front end of the handle gun and the thunder rocket) these two firearms weigh up and down three catties, the end in the hand can be described as light, and there is a simple ignition device, that is, the iron cover on the fire door, tied with the lit arquebus twist, both moisture-proof, can also be pulled to fire), the middle is using the wooden horse to pound the medicine room, the latter is checking the gunpowder, twist, and with a mane cane to clean the breech.

"Bang bang bang", a volley of thunder fired, and clouds of green smoke shot out from the cracks of the bamboo fence, and then scattered and gathered.

Then the middle fan stepped forward, and there was another volley.

After changing and stepping forward, the night sky before dawn was lit up by bullets and rockets, pouring out like a scorching swarm, and the crazy bite penetrated the armor and flesh and blood of the Xifan cavalry, many heroic assault of the Gongfan cavalry, the men and horses rolled over, died in the scream, and the formation of the charge was completely disrupted, most of the war horses were frightened by this gunpowder weapon that was shot in turn, but they were selected after strict training, and under the driving order of the master, they could sacrifice their lives to charge in the face of the rain of arrows, so they did not run around, Those who fall will always fall, but those who have not fallen are still rushing forward!

As for the east behind the bamboo fence, the firepower of the two battalions commanded by Cai Fengyuan was even more than that of Guo Zaizhen's department, and the flames and fire snakes that flew out swept across the black water surface of the Saigon River, shining brightly, and also illuminated the miserable picture of the Xifan cavalry drinking bullets and falling into the water.

Within 100 steps, behind the fence of the bamboo city, the Tang soldiers pushed out wheelbarrows full of large rockets and pushed them behind the earthen walls between the fences, which was conducive to the firing range of the "crows flying artillery".

There are eight chutes on the top and bottom, and there are also blades, swords, and spears on the rocket.

Although Gao Yue's official position is that the name of this weapon is "Crow Flying Fire ****", ordinary soldiers privately affectionately call it "Qiu Niang".

In Bai Letian's "Pipa Xing", there was a sentence "Qu Ba once taught good talents, and made up to be jealous of Qiu Niang", which shows that Qiu Niang was synonymous with beautiful women in the Tang Dynasty, and it was also a collection of love in the hearts of Tang soldiers. As a result, the fiery and blazing firing scene of the "crow flying artillery" easily got the name of the image of "Qiu Niang", and since a battalion general wrote this name on the gun carriage with a brush, the entire camp of the Dingwu Army quickly spread, and it became customary.

The sharp whistling sound of "Qiu Niang" was everywhere, and in the clusters of flying fireworks, countless knives and guns tied to rockets shot out with strong wind, directly causing the Xifan cavalry to be pierced at the same time, killing countless people, and even more rockets slipped into the follow-up Xifan infantry spear array, which was also flesh and blood.

Within 30 steps, the Eastern Barbarians began to throw out the "Earthquake Thunder", this kind of utensils has an iron shell outside, and contains the divine thunder medicine, tiger medicine (poison), iron slag, arsenic, after igniting the twist, it is thrown out like a stone, it is a burst of fire exploding, the poisonous gas is surging, and then the Eastern Barbarian soldiers hold the big bamboo that has not been cut, as well as sharp spears, resist the fence, stretch the spear blade out of the gap, and stab and stab the Xifan soldiers who swam through the trench and pounced.

Zhucheng soon turned into a killing field, and the Xifan infantry cavalry that attacked from two directions was violently blocked by the Tang army's handles, rockets, and earth-shattering thunder, these firearms covered almost all the distance, and combined with the fence and spear, the Tibetan soldiers suffered heavy casualties.

The unlucky Tan Dongchai was hit by a Qiu Niang rocket, the armor was shattered, and the body was burned, and several relatives wearing tiger and leopard skins dragged him back desperately, with only half a life left, and the army of Xugong, which had lost its commander, was in chaos, and they were defeated and retreated to the camp of Liuqiang Town.

In Saigon Sichuan, the Tibetan army charging in Saigon and Lacheng also suffered heavy losses, hundreds of people died and fell into the water, and Sita Yang Zhu braved the smoke of gunpowder and retreated to the high platform on the other side of the river.

At this time, Ma Dingde waited for the opportunity to send a "strong man who dared to die", opened the north gate of Liuqiang Town, shouted and killed, and rushed to the camp of the Dingwu army.

As a result, Xingyuan knew that the soldiers and horses made Gao Gu personally lead five battalions of generals to fight, and Ma Dingde's daredevils immediately turned around and ran to the city - Gao Gu chased after him, and when he reached the north gate, Ma Dingde raised a white flag at the head of the city, shouting "Today, my whole clan votes for Tang, and the city soldiers will not die with me!" ”

So the first five battalions of the Dingwu Army rushed in and hit the city of Liuqiang Town, Ma Dingde and all the clansmen opened the city gates and surrendered in front of the Tang army.

The other battalions of the Dingwu Army launched a surprise attack in turn, storming the Xifan camp and fortress outside the city, Ma Dingde and Lang Xixi each rode horses as the vanguard of the Tang soldiers, and shouted in front of the camp everywhere that Xifan was defeated, and the first to surrender would not die.

The Xifan army and horses of the whole Liuqiang town are in great confusion, some abandon the armor soldiers to surrender, some set fire to the camp and escape, some trample on each other in the melee, to the south of the town to the various mountain roads leading to Taideng City, the corpses of the soldiers and horses are full of soldiers, among them, the defense of the city of Xugong on Dongchai escaped less than two miles, it was unbearable because of the deterioration of the trauma, after dismounting, he drew his sword under a pine tree and killed himself, and his head was cut off by the soldiers of the second team of the fifth battalion of the second battalion of the Dingwu Army, and began to offer meritorious service in the direction of Wangxing City.

In the evening, on the watchtower of Liuqiang Town, which is also the city of Baosai, the black and white Pixiu battle flag was hoisted, and the Sita Yang Zhubu on the bank of the Saigon River saw it, and they were all frightened and desperate.

After Gao Yue and Wei Gao got the good news, they immediately rushed to Liuqiang Town.

Ma Dingde knelt in front of the two horses, Gao Yue and Wei Gao hurriedly helped them up, settled the other party's clansmen, and gave a large number of rewards, Ma Dingde was grateful to Dade, and offered advice to the Tang family: "At this moment, don't rush to attack Taidengcheng, but you can force across the Saigon River, and then break through Siduo Yang Zhu, and stop foreign aid from Xideng, so Taideng City is a Jedi, and begging to hide and cover will collapse without a fight." ”
