April 12 of the first year of Yuanwu of the Tang Dynasty

At this time, Wang Rong was outside Sanjiao City, which was located at the intersection of Sanyuan in the upper reaches of Baoshui, and there was no place to place the army, so he could only let the army fill in waves.

The history of Sanjiaocheng is not long, but it is only one or two hundred years. At that time, it was the army of the Yong Dynasty that went south from the Baochuan Road to take Hanzhong County, and it was here that it held on to the regime that seized Hanzhong County for a long time.

After the Yong Dynasty acquired Hanzhong, it felt that the location here was very important, so it first set up a banknote customs to collect checkpoint taxes from passing merchants and pedestrians.

Later, it was expanded into a mountain city, and the scale of the city was not large, and it could only accommodate thousands of people to move freely.

Now Xue Ting directly arranged 5,000 people to defend the city, and directly overcrowded the small Sanjiao City.

Wang Rong looked at the crowded city and said to Wang Xu: "Let Yuan Tiangang stop using his life brainlessly, which of the soldiers of our armed guard army is golden, directly put on the stone fat bomb and burn it for me."

The march in the past few days has made Wang Rong depressed, he had only heard that the road was difficult to walk, but now he had experienced it himself.

Although the slope is not like Fu Luo Road, "thousands of mountains and birds fly away, and thousands of lonely people disappear." But the difficulty of walking still surprised Wang Rong, in order to protect his war horse, he did not dare to ride a horse, but led the horse step by step to Sanjiao City.

Before the battle, Wang Rong personally surveyed the surroundings with the generals of the Wuwei Army, and came to the conclusion that there was no army here, let alone assemble the trebuchet, because the soil was too soft.

The Craftsman Institute was not placed under the jurisdiction of the Ministry of Industry by Wang Rong, but after the reorganization, in the name of the Craftsman Academy, the General Supervisor and the Ordnance Supervisor were banned, and they were in charge of the Tang State's weapons research and development, scientific and technological development, armaments manufacturing, civilian construction and other businesses.

The Craftsman's Yard was not set up in the city, but in a valley in the Qinling Mountains, and the surrounding people could always hear the sound of explosions coming from the valley.

The new stone fat bomb is the first weapon successfully developed after the reorganization and expansion of the craftsman's institute, and if you know the Molotov cocktail, you will know that this is an incendiary bomb.

The exterior is a slender clay bottle like a Coca-Cola bottle, with a long or short powder rope inserted into the mouth of the bottle as needed, and a ruler on it, which needs to be intercepted to the corresponding position according to the distance.

Yuan Tiangang was standing five miles outside Sanjiao City at this time, the city was small, there were many people, and there was no place for trebuchets and bed crossbows at all. He looked at Sanjiaocheng, which was full of human heads, and frowned.

Bai Su looked at Sanjiaocheng, which was armed to the teeth, and also had a headache, if he really used human life, then Teng Xiangshi would be greatly injured.

Just when the two of them were at a loss, Wang Xu came to the two of them and gave an order with an expressionless face: "The king has an order! Since Sanjiao City likes to huddle together so much, let them continue to be desolate to the earth."

As soon as the words fell, Wang Xu turned the horse's head and ran towards Wang Rong's position.

Yuan Tiangang raised his hand and scratched his hair, and asked Bai Su, "What does the king mean? Do you want to use a stone fat bomb?"

Bai Su nodded and said, "Are those bed crossbows assembled?"

Yuan Tiangang shook his head and said, "This terrain is so narrow, there is no place to put it when it is assembled."

Bai Su said angrily, "If you don't have a place to put it, you have to put it down, at least the bed crossbow is much smaller than the trebuchet. Do you still want to send troops carrying stone greasm bombs to the bottom of the wall and throw them?"

Yuan Tiangang suddenly realized, hurriedly called out to the soldiers under his command, and hurriedly moved to assemble the bed crossbow.

Wang Rong rode on a horse, watched Teng Xiang's movements, and said with a smile to Wang Mo and Zhang Yunshu: "Is this combination of Yuan Tiangang and Bai Su still good, one has courage and the other has brains."

Wang Mo hesitated and asked, "Your Majesty, is this too slow? Wait for the bed crossbow to be assembled and make all the preparations, it is estimated that it will be time for Shen. It will take several hours to attack the city, and then it will be dark."

Wang Rong looked at Wang Hao with a smile and said, "The lives of my Tang Army soldiers are very valuable, I am fed with good food and sweat and blood, not to let them sacrifice on the battlefield, but to win, to win the battle. For this

The goal can be used in any way. I'd rather be slower and steady, better than a few fewer soldiers."

The performance of the Tang army outside the city directly blinded the Bashu army guarding the city, and they took every defense to prevent the attack of the Tang army, but they took over the Tang army but began to fiddle with the crossbow.

This thing may have some power in a city located on the plains, and if it sends a wave towards the city gate, it may be able to break through the city gate. However, Sanjiao City is very special, the city gate is not open in the west, but in the southeast.

This made it possible for the Tang army to get to the southeast if they wanted to break the gate, where the terrain was narrow, the ground was fragmented by the river, and the army could not use it at all.

When the Tang army was ready for battle, thirty bed crossbows were scattered outside Sanjiao City in a pile in the west, south and north. And the shape is also strange, the underside of the bed crossbow is supported by a log stake, forming a posture of pointing at the sky at a 45-degree angle.

The Sanjiao City Guard looked at the scene outside the city in confusion, of course he knew about the weapon of the bed crossbow. The bed crossbow is very powerful in defending the city, condescending, and a crossbow gun can pierce a string of enemies. Siege is not as good as catapults, unless a bed crossbow is used to shoot a crossbow into the city wall to form a ladder that is easy for soldiers to climb. But this is the number of ways to surprise the attack, and it is the first time he has seen the bed crossbow in such a nondescript appearance as the Tang Army.

Yuan Tiangang strode forward, came to a bed crossbow, and shouted, "Listen to my command! Pull the crossbow and wind it! Load the stone fat bomb!"

The bed crossbow is a large clay pot with a wooden stopper, and the jar contains two-thirds of the stone grease, which is projected into the enemy army with a bed crossbow.

Bai Su also came to a bed crossbow and said loudly, "Listen to my command! Rocket ready!"

The front third of the crossbow is soaked with stone grease and tied with a circle of cotton wool, which is ignited and thrown out by the bed crossbow.

The combination of rockets and stone grease brought the enthusiasm of the Tang Army to the enemy, but many enemies may not be able to stand this enthusiasm.

"Put!"

"Bang! — Bang! — Bang! —」

Twenty stone fat bombs were thrown into the air and flew into Sanjiao City in the eyes of the soldiers of the Bashu army.

"Enemy attack! Dodge!"

"Phew! Bang! Phew!"

The sound of the clay pot shattering sounded, and the black stone grease flowed all over the ground, of course, the soldiers of the Bashu army had seen the stone grease, but it was the first time they had seen such a large-scale use of stone grease on the battlefield.

Immediately after the rocket fell on the stone grease, the flames began to ignite, and a Bashu sergeant was very miserable, he could not dodge the clay pot, he was drenched by the stone grease, and a little spark happened to touch him, and then, his whole person became a torch.

"Ah! ——」

A terrible howl rang out, and the Bashu soldier ran to his comrades, begging them to save him. Two young men did not understand the horror of the flames, and rushed forward to save them, but they also set themselves on fire.

Such a scene made others dare not go up to save at all, but Sanjiao City was so big, and within a quarter of an hour the Tang army outside the city, hundreds of clay pots were thrown in. There is already stone grease everywhere in Sanjiao City and the city, plus the rockets that are thrown at the head of the city and the city.

Among the 5,000 Bashu defenders, more and more soldiers were set on fire. In the end, the Bashu army, which couldn't stand it, took the initiative to open the gate of Sanjiao City, and they began to run wild when they got out of the city gate, hoping to run to the Bashu camp in the south.

However, they miscalculated, the horsemen had already been waiting here, and in the end, less than 100 of the Bashu defenders in Sanjiao City fled, and the rest either surrendered or burned to death, not even the wounded.
