Sun Xiaozhe looked at the shattered military tents and the stumps and broken arms all over the ground, and his face was extremely gloomy and ugly. The most shocking thing is that a stone bullet of dozens of catties actually smashed the ground into a large pit several feet deep. If the Tang army fired more than a dozen of these flying stones at a time and shot several rounds in a row, wouldn't his military camp have to be beaten into a sieve?

This thought made Sun Xiaozhe suddenly frightened, and he shouted and ordered: "Order, the army will pull out the camp and retreat five miles!"

As early as the morning, Sun Xiaozhe received a change about the head of Xin'an City, he didn't care at first, the guards in the city like to tinker with some tricks and tricks, maybe it will have a temporary effect, but the siege and defense of the city is fighting for grain and grass and men and horses, and the Yan army is far superior to the Tang army in any aspect, so it is also tossed by those people. But they never imagined that a tentative shot by the Tang Army would bring them great panic and trouble.

After a night of tossing and turning, after the sky was bright, the large army company camp was finally re-encamped, but the soldiers were also so tired and exhausted that the daily routine raids and sieges had to be suspended. Sun Xiaozhe raised his eyes to look at the dazzling sun, and suddenly remembered the old man who predicted that there would be heavy snow in three days.

Just yesterday, An Qingxu actually sent an envoy to urge him to speed up the march, and hoped that he would better take Tongguan when An Lushan ascended the throne, as a congratulatory gift to congratulate the founding of Dayan and the emperor's accession to the throne.

Sun Xiaozhe and An Qingxu have always been at odds with each other, and both of them don't like each other. An Qingxu's move will definitely not be out of good intentions, and it is likely that he will make a big fuss about the slow speed of the army, and maybe he will also make slanderous remarks in front of An Lushan.

The reason why he was reluctant to attack Xin'an before was that he didn't want his elite men and horses to lose too much in the westward advance, and at the same time, he was also waiting for a timely heavy snowfall, and then sneaked across the soap river valley and attacked the rear of Xin'an.

It seems that the pace of attacking the city is going to be accelerated, Sun Xiaozhe secretly made up his mind, if it doesn't snow today, he has no choice but to order a strong attack, even if he fights to lose his troops, he can't lose An Lushan's favor. With a lot of worries, he discussed the weather with the guards around him and asked them if they thought there would be heavy snow tonight.

Those guards were all in a hurry, and of course they couldn't say a meridian. But one of them wanted to speak and stopped, Sun Xiaozhe saw it strange in his eyes, and asked: "If you have something to say, it's okay to speak, don't spit out, you know my temper!"

"Yes! Yesterday, the old man came to see the general, saying that Xin'an City was preparing oil and was still cutting wood, so the general should deal with it carefully......"

"Oh?"

This surprised Sun Xiaozhe, but he didn't expect that the old man also had some means, it seems that this person must have an internal response in Xin'an City, as for the situation he said, it may be a few stone cannons erected by the Tang Army at the head of Xin'an City.

"Would you like to see the old man?"

Seeing that Sun Xiaozhe's face softened, the soldier asked tentatively.

"No, he's already said what he knows, it's the same whether he sees it or not, if there is a heavy snow tonight, he will really have to reward it again!"

Sun Xiaozhe urgently needs to break the deadlock now in order to block An Qingxu's mouth and save this guy from creating trouble for himself behind his back.

"Give the order to go down, the army will rest during the day, and be ready to attack at night! Also, tell the old man that once it snows heavily, please work hard and lead the way!"

Suddenly, Sun Xiaozhe felt that he had neglected something, and after thinking for a long time, he finally suddenly became alert, judging by the current situation, the Xin'an County Lieutenant must be a cunning person, how could he be completely unaware of the hidden worry of the Saohe River Valley?

Thinking of this, Sun Xiaozhe was a little excited, and at the same time hesitated whether he should take the risk of carrying out the strategy of sneaking across the valley of the Soahe River.

Some people also questioned that Fan Changming was a spy of the Tang Army, but after careful investigation, Sun Xiaozhe dispelled this concern, this person's two sons died because of the Xin'an County Lieutenant, it is said that the Xin'an County Court also sent people to Changshi Township to lock up all the Fan clansmen, who will be angry with the person who has a grudge against his son?

……

After a day and a night of rushing work, ten stone cannons were assembled on Dongguan City, and this time they chose a longer, stronger-looking mulberry wood to be processed into throwing arms.

"Shaofu-kun, do you want to try another salvo?"

Yesterday's second test firing, the throwing arm was broken because of the unbearable pull, which made many people angry. The military camp outside the city was opened overnight, retreated to five miles away and re-settled, everyone saw that if the throwing arm could not be broken, or if there was a spare throwing arm at that time to change it in time, at least more burning stone bullets could be fired, on the one hand, it could kill and injure the Tibetan army, and on the other hand, it could continue to deter the Tibetan army.

Qin Jin nodded happily, he also wanted to see how powerful this stone cannon salvo was!

A moment later, the wind whistled, and ten stone bullets weighing dozens of pounds were sandwiched with fireworks and projected into the sky, heading to the end of the pole. He didn't expect the cannon to have a range of more than five miles, but as long as it could create a sustained and effective damage, it would hold back the rebels' siege as much as possible.

The range of the stone cannon did not exceed five miles, but the power still shocked everyone in Xin'an City.

Just as everyone was amazed, one of the solidarity soldiers suddenly asked, "What if the rebels also made such a sharp weapon?"

His words made everyone stunned, including Qin Jin, of course. The stone cannon technology is simple, the manufacturing process is not complicated, the carpenter can make it as long as he studies a little, and many books related to the craftsman also have various records of the stone cannon, I believe that the main general of the rebel army as long as he has the heart, may not be able to create this powerful and simple structure of the big killing weapon.

For a while, everyone's excitement came to an abrupt end, and it was obvious that everyone agreed with this simple inference, the power of the stone cannon was obvious to all, and the stone bullets weighing dozens of pounds were smashed into a large pit several feet deep when they were smashed on the ground and smashed on the rammed earth city wall? If there were enough stone bullets, dense enough, the destruction was absolutely unimaginable.

At this time, Zheng Xianli, who has always been reluctant to express his opinions, came forward and said: "You don't know, the Hu people are good at fighting formations, but they are not good at skills, and it is not easy to make stone cannons in a short period ......of time."

Now the soldiers and civilians of Xin'an know that this general surnamed Zheng was once Feng Changqing's personal entourage, who had defended the border generals in the Western Regions for more than ten years, and had fought countless battles with the Hu people, so his words were naturally convincing.

The gunners, who were responsible for manipulating the gun, continued to test fire, and they even came up with a way to change the range of the gunpowder by controlling the curvature of the stretching arm.

This day was calm and made Qin Jin somewhat uneasy, and now the people in Xin'an have learned that the chief commander of the tens of thousands of Fan Hu rebels is Sun Xiaozhe, for this person, he still has some impressions, the history books record that this person was left in Xijing, he was ordered to slaughter dozens of Tang Dynasty clans such as the eldest princess of Huo Guo, and brutally cut them out of their hearts.

In the face of this kind of character, it would be a lie to say that Qin Jin had no psychological pressure. He didn't know how many catties and taels his opponent had, but most of the Anshi rebels who could leave a name in the Anshi Rebellion were not incompetent. He knew that he couldn't underestimate the IQ of the ancients, so he had planned to burn the Soap River Valley, and after thinking about it carefully, he felt that it was a little taken for granted.

Even if Fan Changming really successfully connected with Sun Xiaozhe and successfully confided in him the weakness of Xin'an, how could Sun Xiaozhe not assess and measure the risks? If he was really stupid enough to run into it, then why did An Lushan reuse such a fool?

After this kind of fluke faded, Qin Jin began to think about the way to defend the city again, so he had a big killing weapon like a stone cannon.

Since the rebels did not attack during the day, Qin Jin was extremely vigilant at night, and even stayed in Dongguan City all night, but the rebels did not attack until dawn. As the sun rises, everyone's nervous hearts gradually let go, and the moment of dawn is the most reassuring, both friends and foes are cooking.

Suddenly, someone let out a rapid exclamation:

"Oh my God, look, what's that!"

When Qin Jin heard this, he looked out of the city. I saw two stone cannons suddenly appear in front of the rebel barracks, each of which was pushed by dozens of people, and was slowly moving in the direction of Xin'an.

Everyone was stunned, but they didn't expect that the solidarity soldier's fears would become a reality overnight. Everyone knows that the Xin'an city wall is dead, and it can only bear it silently in the face of the blow of the stone cannon......

Che Bihe, who has always been brave, immediately said that he would take the brave men out of the city to destroy the two stone cannons. Qin Jin didn't even think about it, so he rejected the proposal. In his opinion, the lives of his solidarity soldiers were much more important than those two stone cannons. What's more, the rebels can get two stone cannons in one night, and even if they destroy these two, they can quickly build a third and a fourth......

"All the stone gunners, take your place, the time has come to test you!"

After Qin Jin's reminder, the stone artillery players immediately reacted.

"Quick, quick, the cannon, pull the rope tight!"

"Load up the stone bullet and greet the dog!"

"Put!"

The rapid friction of the wooden shaft and the whirring sound of the stone bullet breaking through the air suddenly sounded!

"Smashing the empty ......"

The united soldiers in the city erupted in regret, and ten stone bullets were thrown far behind the opponent's stone cannons.

The gunners were not discouraged, the first round was just a correction of the landing point, and they used their best strength.

"Brothers, loosen your grip and tighten the rope......"

"Send the dog back to his hometown!"

Some people even took off their pants and urinated on the stones.

"The boy urinates to ward off evil spirits!

In a word, everyone in the city was amazed!

The stone bullets fired another volley, drawing arcs against the rising sun......
