Ten Kamui cannons lined up in the open space in the center of the inner camp. Previously, these Shenwei generals were placed on the fort near the left side of the outer camp, and that was because Lin Jue was worried that the other party would have large siege equipment to attack, so the Shenwei cannon was still useful. After all, a solid cannonball can destroy any siege machine with just one hit, and it may be useful when it matters most.

But the other side did not have siege equipment at all, and relied entirely on manpower to attack. It is impossible to bombard the opponent's soldiers and horses with the cannon of General Kamui, the cost performance is too low, it is better to shoot a few bows and arrows.

When the outer camp was about to be broken, Lin Jue gave the order to retreat. The first person to be dragged to the inner camp by the carriage and horse was General Shenwei's cannon. A swarm of bazooka shells can be discarded regardless of it. After all, that thing has no inner core and rocket, and it is just an ordinary conical fine iron cylinder, and throwing it to the Jurchens will not cause any consequences. But Shenwei can't leave the cannon behind, if the Jurchens get these cannons, the Jurchens will definitely imitate and promote them, and they will become troubles. In the future, no strong city will be able to stop them. Lin Jue was even prepared, if the army was defeated here today, it would be necessary to blow General Shenwei into pieces, and he would definitely not let the Jurchens get this kind of siege weapon.

The inner camp was in a hurry, Lin Jue didn't want to get caught up in the final melee, just now, he saw the location of Wanyan Aguda, and decided to use the Shenwei cannon to carry out the decapitation operation. The location of Wanyan Aguda was on the earthen platform on the inner side of the outer camp, and it was two miles away from the center of the inner camp. The maximum range of Shenwei's cannon is no more than two miles, and it is a headwind, so Lin Jue is not sure about this matter. But after some calculations, Lin Jue thought that if the amount of gunpowder was increased, it would be possible to give it a try. Although there is a danger of exploding, there is not much to care about at the moment.

The biggest problem is that Kamui General Cannon's cannon is a solid iron cannonball, and it is too difficult to hit a person two miles away. It's like shooting a fly a hundred paces away with a bow and arrow. It's even harder than that. Moreover, this method only has one chance, once it fails, Wanyan Aguda will inevitably be frightened and hide or distance himself, and there will be no more chance.

Therefore, in addition to calculating the launch angle and adjusting the accuracy, Lin Jue decided to fire ten divine power cannons at the same time to increase the probability of hitting by ten times. The target is not on Wanyan Aguda, the target is too small. The target is set on that earthen platform, so that the target is large enough and the error is relatively small. As long as it can hit the earthen platform, with the power of the iron cannonballs of the Shenwei general's cannon, the earthen platform will be blown apart, and the Wanyan Aguda on the earthen platform will be affected. As long as you are lucky, you can kill him.

In fact, Lin Jue was not sure about the result, and he rarely made this kind of decision that the uncertain result mostly depended on luck to achieve. But today he had no choice, because the Jurchens did force him to take this step. The source of all the Jurchens' bravery and fearlessness of death lies in Wanyan Aguda, and as long as Wanyan Agu Da is solved, the Jurchen army will inevitably collapse, there is no doubt about it.

Liang Qi and Ruan Ping personally led hundreds of people to set up the Shenwei cannon according to Lin Jue's request. Although they were a little puzzled by Dashuai's decision, they never thought to question Dashuai's decision. Lin Jue also took matters into his own hands, measuring the angle of the muzzle with a wooden protractor, measuring the change in wind speed from time to time, and muttering to himself from time to time. The limited knowledge I learned on the earth back then finally came in handy, and my teacher said, 'Learn mathematics, physics and chemistry well, and you won't be afraid to go all over the world', I thought it was just a slogan at the time, but now I really realize the correctness of this sentence. If you learn mathematics, physics and chemistry well, you will not only be afraid to go all over the world, but you will also not be afraid to cross over.

Two more gaps have been broken through on the north side of the inner camp, and the battle has entered a white-hot stage. The cavalry of the Luoyan army was insufficient in number, and had to use infantry to surround the Jurchen cavalry that was constantly rushing in. The casualties on both sides were very serious, and the number of casualties of the Luoyan army was far lower than that of the opponent before, because they refused to defend the camp and attacked the opponent with firearms, bows and arrows, and did not engage in a frontal battle, so the casualties were not large. But from a certain moment on, the casualty figure of the Luoyan army skyrocketed, and it had already exceeded the immediate number of dead and wounded of the Jurchen army. Ma Bin was already preparing to ask tens of thousands of people who were rushing to the front to encircle the opponent, because the openings that were broken through everywhere needed manpower to intercept them, and they were already a little overwhelmed.

The sound of killing everywhere shook the sky, and the screams were endless. Lin Jue turned a deaf ear, concentrating on calculating the angle of each cannon, lying on the ground covered in dust, his face was full of beads of sweat. Finally, after all the ten Shenwei cannons had been erected, Lin Jue sighed and said to Liang Qi: "Brother Liang, get ready to launch." Remember, triple the dose. The breeches and shells must be cleaned. In addition, make it clear to the brothers that three times the amount of gunpowder is likely to explode, so let everyone be careful. ”

Liang Qi arched his hand and said: "Don't worry, Dashuai, I will light the fire myself." ”

Lin Jue patted his arm, nodded and said, "Be careful, do it." ”

Liang Qi gave a loud order, and the gunners quickly stepped forward, quickly checked the inner chamber of the ammunition, then filled the ammunition, pulled out the fire rope, and made preparations. The people on the left were all ordered to take a few dozen steps back and find cover to dodge, just in case of a bombing.

Lin Jue re-ascended to the command platform, raised the clairvoyant mirror and looked at the location of Wanyan Aguda. Coincidentally, Na Wanyan Agu was standing on the earthen platform and looking at himself with a clairvoyant mirror. Wanyan Aguda's movements froze for a moment, obviously he also recognized himself. The corners of his mouth were grinning, as if he was watching himself laugh mockingly. Lin Jue also grinned in return, and at the same time raised his hand and waved towards Wanyan Agu, waving goodbye. The next moment, the palm of the hand was like a knife, and it was violently swung down. That's the signal emitted by the ignition.

Liang Qi below got the signal and ordered loudly: "Point...... Fire......! Launch! ”

Ten gunners, including Liang Qi, moved in unison and lit the arquebus with torches. Then everyone quickly ran and evacuated, and rushed to a dirt pit dozens of paces away, holding their heads and lying down.

Everyone's eyes were fixed on the ten Shenwei General Cannons standing quietly on the ground with their heads held high, the wind blew, the sparks on the fire rope flew everywhere, the green smoke rose, and the sneering quickly burned. Soon, all the fire ropes burned into the breech chamber, and there were no more sparks to be seen, everything seemed to freeze in an instant, and everyone stared at Kamui General Cannon with worry, horror and anticipation.

"Boom! Bang! Bang! The huge roar resounded through the world in an instant, shaking everyone within 100 steps around their ears and dizziness, and some people's ears and noses were shocked and bleeding. The ground within a hundred paces seemed to shake in an instant, and the mud and other things on the ground jumped. A fine layer of smoke and dust rose from the entire ground.

The soldiers and horses of both sides who were fighting on the periphery were stunned by this loud noise in an instant, and hundreds of war horses stood up in fright and screamed. In addition to that, the entire battlefield fell silent at the moment of the loud noise.

Lin Jue's ears were also ringing, but all his attention at the moment was focused on the earthen platform in the distance. He could see clearly in the clairvoyant mirror, and he saw two huge smoke and dust bursting out from the side of the earthen platform, and his heart suddenly felt cold. It was obviously a missed shell, one left and one right, with a deviation of about twenty paces. But the next moment, the whole platform exploded like an erupting volcano. In the smoke and dust in the sky, the Jurchen banner flew in the air, and there were seven or eight humanoid objects flying in the air.

Lin Jue was overjoyed and jumped up like a child. Laughed and said, "Hit! At least five shells. ”

Bai Bing, who was beside him, also saw the explosion of the earth platform, and shouted excitedly. Lin Juexi couldn't help but have nowhere to vent, and suddenly hugged Bai Bing and lifted her high.

Lin Jue's guess was right, there were a total of six iron cannonballs that hit the earthen platform, and the six big iron balls smashed fiercely on the upper part of the earthen platform with a square radius and a height of two zhang. The structure of the platform was loose, and it was just a simple pile of dirt and mud bags, and its purpose was only to elevate the position to give a swarm of bazookas a condescending angle to launch and pass over the heads of the defenders on the city walls. The power of General Kamui's cannonballs had already been demonstrated when he attacked the south gate of Bianliang, and although the huge iron ball did not have the power to explode, the effect of smashing into the earth platform was also powerful. Like a hammer hitting a watermelon, the cannonballs that rush to the earth lift the dirt up, with an alternative explosive effect. The six pieces are even more powerful.

The force of the impact lifted the people on the earth platform into the air, and the earth was thrown into the air like rag dolls, and then fell hard.
