Xu Zhen was injured, and there were many night police sergeants in the city of Ganzhou, traveling around, with noisy footsteps, and there were more oxen pulling bricks, stones, wood and bamboo, strengthening the city defense, so he took a nap all night and woke up at every turn, which was quite unpleasant.

The next day, although the sun rarely shines, but because of careless living, diet is not fine, so that the body is turbid, the spirit is really sluggish, read last night through the "increase in the performance of the I Ching to wash the marrow of the inner strength", so I washed up, purified the body, according to the method for half an hour, really refreshed, the spirit is greatly lifted.

Then, according to the diagram in the internal exercises, he played with the posture of the dragon, tiger, eagle and leopard, and reviewed the cartilage yoga technique in the Seven Holy Swords.

Yan Lide ordered someone to bring breakfast early in the morning, filled his stomach with Xu Zhen, and hurriedly dragged Xu Zhen to the craftsman's camp.

Due to the accident in the last experiment, the craftsman camp suddenly became a dangerous place in the army, and no one dared to approach, so they had to drive a group of military slaves to work here, and the entire craftsman camp was filled with a depressing tense atmosphere.

The drawings that Xu Zhen delivered to Yan Lide last time were not bed crossbows, nor stone throwers, but genuine artillery, imitating the design of the heavy weapon "Shenwei General" in the Chongzhen army, and after Xu Zhen's wonderful transformation, all copper casting, it is bound to make a weapon to shock the world!

At that time, the artillery body and artillery carriage were all complete, and they were suffering from the consideration of the ammunition ratio and the amount of filling, so Li Chunfeng was transferred to Ganzhou to drive, but the ordinary black powder could not meet the demand at all, and Xu Zhen had no ammunition formula in the drawings, so he urgently called Xu Zhen.

In the barracks, there are many large stone bullets stacked, many military slaves are beating and beating, and the round bullets are being sharpened, and pottery models are erected around the furnace, which are displayed in cast iron bullets.

Xu Zhen's artillery, according to the system of the Yuan and Ming dynasties, with copper and iron as the tool, such as a barrel, more than eight feet long, weighing more than 1,000 catties, in the real medicine, and with stones to plug its mouth, bypass a line, with fire, the range can reach two miles, the sound and prestige are equally important, very amazing.

Stroking the heavy cannon in front of him, Xu Zhenxin inevitably surged with pride, although he was immersed in magic, dabbled in the principle of blasting, and was even more obsessed with playing with fire, but he really put the cannon in his brain into experiments, whether in the present world or in the Tang Dynasty, it was the first time!

Seeing that Xu Zhenai didn't let go, and looked at the heavy cannon, Yan Lide also rolled his eyes again and again, and muttered in a low voice: "Don't underestimate your old brother's ability, just a copper cannon, what is the difficulty, you come with me." ”

Xu Zhen saw that he was as tall as a rooster, so he moved to the open-air warehouse behind the craftsman's camp, but saw seven identical heavy guns lined up in front of him, the barrels were bright, and the gun carriage and gun carriage were as solid as a platform, which made people secretly shocked in their hearts!

"What a good trick for my brother! Ha ha! Xu Zhen was overjoyed when he saw these heavy cannons, but Yan Lide pursed his lips and complained dissatisfiedly: "There are heavy cannons but no gunpowder, what is the use, after a certain merit, the rest is up to you!" ”

Xu Zhen praised again and again, and immediately went to the northwest of the craftsman's camp to find Li Chunfeng, and jointly studied the theory of strong medicine.

"Such a powerful ordnance can be called a heavy weapon of the military state, and it is not intended to be named, how can it be passed down for thousands of generations!"

Yan Lide's heart sank, obviously shocked by Xu Zhen's arrogance, and immediately asked: "In this case, what name should it be called?" ”

Xu Zhen touched his chin, pondered for a moment, his eyes suddenly lit up, and he said to Yan Lide: "This cannon can be called a real martial general!" Don't you want to kill people quickly and engrave them on the cannon body? ”

Yan Lide didn't think much about it, and ordered his subordinates to engrave the name of the cannon, and then went to see Li Chunfeng with Xu Zhen, but he suddenly woke up halfway through the journey and suddenly realized that the name of the cannon was fake, and this son was worried that the credit would be taken away!

This cannon is derived from Xu Zhenzhi's conception, the name is Zhenwu, with the name of Xu Zhen, if he rises to the world, Xu Zhen's name will spread far and wide, and there are still people in the army who dare to disobey him?

"What a cunning boy!" Yan Lide is a master craftsman, and he is honest and open, he does not need to covet Xu Zhen's merits, Xu Zhen also believes in Yan Lide and Li Jing's people, but he needs to beware of others greedy for his merits, and now he is the target of the public, and he has to quickly improve his status in the army, otherwise he will not be able to get rid of the fate of the chess pieces after all, and he will be manipulated by others at will.

Xu Zhen's move also made Yan Lide keenly smell the danger in the army, and the battle behind the scenes in this battle may be much more tragic than the frontal war.

Li Chunfeng dabbled in hundreds of schools, and he had a deep understanding of the secret methods of Taoism, and he was no stranger to Danding and his ilk, but the gunfire was blazing, and he didn't recognize people, and he couldn't urge the iron bullet if he was too soft, and he was afraid that it would not be easy to control.

Seeing that Xu Zhen and Yan Lide came together, Li Chunfeng couldn't help but be overjoyed, this Xu Zhen is also a young man with real skills, not to mention his quick thinking, he is quite familiar with the medicinal properties, the ratio of nitrate and dansa is proportional, there is a law, his hands and feet are cautious and his mind is meticulous, but it is for Li Chunfeng to have a good insight.

The three of them were busy with their work, but they heard the shouts outside the camp to kill the heavens, Xu Zhen's face sank, and he rushed out, only to see the wild sergeant rushing out from the gentle slope of the tunnel entrance like a tidal wave!

"But the secret passage has been discovered!"

Li Chunfeng and Yan Lide glanced at each other, and couldn't help but turn pale, these two don't have martial arts!

Xu Zhen came easily, did not wear armor, and only had a long knife in his hand, seeing that there were many clay pots in the craftsman's camp, he ordered the military slaves to fill the gunpowder that had just been prepared into the clay pots, inserted them into the line of fire, and sealed the mouth of the jar with sand and stone beeswax, and ordered the military slaves to carry the fire sickle with them and follow him out to fight the enemy!

Li Chunfeng and Yan Lide saw that these military slaves were careless, and they were afraid that they would blow up their barracks carelessly, so they hurriedly took the clay pot in the hands of the military slaves and walked out with Xu Zhen.

These military slaves were so frightened that they couldn't possess their bodies, and they were hoping that Li Chunfeng and the others would take over them, so they hurriedly hid, while Xu Zhen took the two of them to the street.

The wild captives were very fierce, and as soon as they stepped on the ground, they rushed to kill in all directions, and the town defenders hurriedly brought in archers and sealed the entrance with a rain of arrows!

However, these wild captives came prepared, the spear and shield soldiers were in front, the crossbowmen were behind, the front servants followed, three or four people held up a huge wooden shield, and the shield was instantly filled with feather arrows, but the wild captives and crossbowmen looked at the gap and shot everywhere, moving forward step by step, and actually laid a fan-shaped defensive battle formation at the entrance, but there were more and more spear and shield soldiers and crossbowmen pouring in at the entrance behind them!

With the increase of personnel, the fan-shaped battle formation is wider and wider, and the enemy's army is becoming more and more dense.

If you talk about breaking the shield array, it is natural that a large number of cavalry charge with a lance is the sharpest, but the terrain is narrow, and the cavalry cannot spread the formation at all.

At the moment of the situation, the defenders can only use strong bows and crossbows to continue to pour arrow rain, shoot the enemy's position, slow down the speed of the opponent's progress, but the opponent is prepared, the fan shape is expanding more and more, the enemy's point shooting is more sharp, the defenders have to concoct according to the law, and also summon spear and shield soldiers, lined up into a barrier, in order to block the opponent's bow and arrows.

The two sides reached a stalemate, every moment someone was hit by an arrow and fell to the ground, the long shield had already been shot into a hedgehog, and many generals were also anxious, constantly deploying troops, but I don't know who questioned it in the chaos.

"Why did Xu Zhen's people just arrived yesterday, and today these wild captives have found the door!"

"We and other soldiers are working hard here, where are Xu Zhen's people!"

"This erector is mostly close to Shengman, and there is no shortage of savages and people under his command, so he can't say that he sold me!"

"I heard earlier that this person was suspected of defecting to the enemy when he was in Shanshan, but he was suppressed by the head of Li Daozong, so it is possible that he will come to harm our robes again?!!!"

"Why don't we kill this fang and show it to the public, so as to deter the enemy and strengthen the heart of our army!"

In the panic, some people made something out of nothing, and others had to add fuel to the fire, the brothers in front were still working hard, but the rear had already regarded Xu Zhen as a traitor who collaborated with the enemy and betrayed the country.

Xu Zhenbu was placed in the west of the city, some distance from the place where the incident occurred, and when the news arrived, it was a step too late, and many soldiers who were deceived and bewitched became more and more suspicious!

Everyone is bent on killing the enemy and going to death tragically, who wants that there are still people who are fiddling with intrigue and framing in the middle of the war? The brothers in the rear saw that the robes in front of them had fallen one after another, their hearts were broken, and their fears became more and more intense, and they seemed to raise their eyes to look around, and there were enemies all around, and after hearing the rumors, they were even more indignant.

Zhou Cang and Gao He Shuyinzong and others are all reckless and hot-blooded people, and there is no Xu Zhen and Zhang Jiunian City Mansion, if they are a little stronger, how can they be wronged in vain and humiliated in vain!

Zhang Jiunian was looking around, using both eyes and ears, hoping to secretly find out the black sheep, but Zhou Cang and the others couldn't resist the disdainful gaze of these **, and scolded back, the two sides were tense, and they were about to explode!

Xu Zhen came in a hurry, but when he saw such a scene, he couldn't help but feel disheartened, how could it be that no matter where he went, someone always stumbled on himself? The people behind the scenes are really so hand-eyed, even under the command of Wei Gong Li Jing, there are minions and poisonous snakes lurking?

However, this is not a good opportunity to scrutinize the inside story, the entrance to the secret passage is very secret, if there is no intelligence, the wild captives will not be able to find out, and now they can only press their anger, retreat from the enemy first, and then catch the ghost!

Thinking of this, Xu Zhen was not verbose, took the long knife, struck the fire sickle to light the torch, got on the horse, took the clay pot in Li Chunfeng's hand, and suddenly clashed in.

Xu Zhen shouted: "Zhou Cang, Gao Heshu, take the shield and give Captain Bendu a cover!" ”

The two of them had nowhere to vent their worries, and after listening to the order, they held the long shield in one hand, grabbed their own blades, struck their horses in front, braved the rain of arrows, passed through the shield array, and charged towards the enemy!

But I saw that the two of them were heroic and brave like the heavens, Zhou Cang's strange knife was like a door panel, and Gao Heshu dragged dozens of catties of iron thistle bones, but the long shield in the hands of the two needed three or two men to work together to lift, but the two of them lifted the weight like light, and the war horse was a little difficult!

Xu Zhen followed behind the two, as if he had entered a safe haven, the rain of arrows could not be touched, and seeing that there was only ten steps away, he immediately lit the line of fire and threw the clay pot over!
