The pitch-black cannonball flew out with the force of the catapult, because a cannonball weighed only a few pounds, and it was not as bulky as a stone at all, so the range could be farther than that of a stone, and in addition, it was a regular circle, and there was less resistance to the wind in the air, so the range was further increased.

These are all accurately calculated by Zhou Yi and several old gentlemen, not only to let the cannonball eject out at the fastest speed, but also to temporarily slow down its explosion, so that if it is not launched when it is launched, it can be cleaned up in time to reduce the damage to itself.

Since Zhou Yi has decided to make such a new weapon, he naturally has to take into account the harm caused by this new weapon and the methods of prevention.

Although these weapons he made were not even the most rudimentary compared to the weapons of a few hundred years later, in the land of the twelfth century, this was the most powerful weapon of mass destruction in the world, and there was no one.

Below, although the thistle terrestris caused trouble to the cavalry, its effect was not as great as Zhou Yi imagined, but it was understandable that this commonly used trick had already been dealt with by Jin Bing compared to him, which was not surprising.

They quickly approached the city gate, and the soldiers and siege engines behind them came unharmed to a distance of thirty feet from the city gate, which was a very short distance, and the city gate was close at hand.

There was silence on the castle tower, not only those stones with great lethality, but also not a single feather arrow, which filled everyone's hearts with doubts. One of the horsemen holding a shield was really full of curiosity, and he moved his shield slightly to look upward.

He saw a pitch-black thing flying down from the city gate, oh no. Not one. It's many, many of them. These things smoked, but there was no sound, and then, these things fell......

The silence of the "boom ......" was broken, and the loud roar was like thunder, and the black, smoking thing fell to the ground, and suddenly exploded before everyone could see what it was.

This is the first time that Zhou Yi's Shengli No. 1 bomb has been tested on the spot, and Zhou Yi has seen it. With the sound of explosions, a vacuum area suddenly formed around it, and a small rain of blood appeared, and then there were continuous screams, and those steel balls entered the soldiers' bodies, but some of them could not hit the vital parts but could not kill people for a while, this pain can be imagined. And then there are the horses, which are frightened mainly by sound, and the deafening explosion makes them panic.

A series of explosions rang out, and the neatly lined up teams were instantly bombarded in all directions. The war horses were already running wildly without control, and without the cover of the cavalry shields, even if the steel balls were hit in the vital parts, a large number of them could kill people.

Zhou Yi looked at the Jin soldiers below with a smile on his face, completely unable to resist under his own attack. I feel infinitely happy in my heart, what I want is this effect, and what I enjoy is this rhythm, that is, I want to hit you until you don't even have the heart to resist.

Looking at the people below, Yue Fei and Lin Chong were dumbfounded, although it was not the first time they saw Zhou Yi playing with the opposite side in applause, but today was different, the power of the black thing smaller than a football was the reason for their shock.

"That...... Lord Zhou, is it really okay for us to be like this? Yue Fei swallowed a mouthful of saliva and said with difficulty, watching the people below die one by one, the horror in his heart was beyond his imagination.

Zhou Yi said disappreciably: "What's wrong with this, they didn't feel bad when they killed me Song Jun, are you right, since he can kill me, why can't he kill me?" Hey, I'm saying you're having another unicorn attack? ”

Yue Fei asked curiously, "What is the Qilin Arm?" ”

Zhou Yi patted him on the shoulder, and said earnestly: "Pengju, I am very pleased with your diligent and studious spirit. ”

Although he didn't understand what Zhou Yi meant by this, since Zhou Yi wanted him not to ask, Yue Fei naturally shut up and looked at the book of war intently, he had read the book of war for more than ten years, and suddenly at this moment, he felt that the things on the book of war seemed to be the same thing, and the strategy was only used when the strength of the two sides was about the same or the enemy was strong and I was weak, and in the face of absolute power, all strategies were ridiculous.

This kind of battle lasted less than half an hour, and the ground below was already full of corpses, these people may have been killed directly, or maybe the steel balls that catapulted everywhere took their lives, in short, they had not experienced such a war, and could not see the war of their opponents. At this moment, they may also be able to understand the mood of Yelu Dayi, who had said ten days ago that I would rather fight with Jin Bing than attack Yanjing. At the beginning, Jin Bing was still very angry, didn't he look down on my big gold? Until now, after they have personally experienced the battle against Yanjing, maybe they will be able to understand what Yelu Dayi said, and then after meeting him, they will say to him, brother, I would rather fight with myself than provoke Yanjing again.

This kind of novel war weapon, coupled with such a tricky gameplay, Zhou Yi is already invincible, at least he has proved that he is already invincible in the defense of the city, as long as the ammunition is enough, no matter how many people you come, it will definitely be until you don't even know your parents.

At this time, someone suddenly came to Zhou Yi's side and said, "Lord Zhou, the big thing is not good, our ammunition has gone seven or eight out of ten, and there is not much left." ”

Zhou Yi was stunned, and then remembered that it was strange that there was enough ammunition to play like this for a few hours without stopping, but can you give up now? Absolutely not, as long as they stop, the Jin soldiers below will definitely know, and when the time comes, they will forcibly attack the city, it will be bad.

"Okay, I see, you go down." Zhou Yi said quietly.

Hearing this, Yue Fei asked, "Then what should we do now?" ”

Zhou Yi looked at the Jin Bing, who was already less than half of the number of people below, and said, "Don't worry, we will get through the difficulties, I bet they won't last an hour." At most, after an hour, they will withdraw their troops. ”

"Why?"

"No, why, if they don't withdraw their troops after an hour, you and Lin Chong will lead the troops down to kill them, and there will be so many people left, I believe you will win right."

Finally a task came down, Yue Fei and Lin Chongdou looked very excited, after waiting for such a long time and watching such a long play, they were finally able to play. Both of them were gearing up, and Lin Chong said, "Then I'll go and prepare now." Yue Fei was naturally not to be left behind and followed out.

The Jin soldiers below are indeed quite resistant, in Zhou Yi's opinion, the main thing is that the shield plays a great role, and the steel ball can't penetrate the shield when it hits it, which is much thicker than the armor.

The Liao army's preparations in this regard were completely inadequate, unlike Jin Bing, who knew what their duties were and what they needed to do. Perhaps this is one of the reasons why the Liao army was defeated in front of the Jin soldiers.

After another hour, Zhou Yi saw that the number of people below was only tens of thousands, so he ordered the shells to stop projecting, and at the same time, Yue Fei and Lin Chong had already led people out of the city from the tunnel.

When the Jin soldiers below noticed that the shells above were no longer falling, they all showed joy on their faces, and they breathed a long sigh of relief in their hearts, this maddening feeling is finally going to pass, Dajin's spring is coming, Yanjing City, prepare to tremble under Dajin Tie Ride!

But their excitement didn't last long, and then they found that they didn't know when, and there were many people in the grass in all directions, and a large number of Song troops poured over like a tide.

The Jin soldiers are now less than 30,000 people, and most of them have lost, and the generals are ready to find an opportunity to evacuate, until they find that there are no more shells falling on the city tower, and the hatred in their hearts suddenly comes up, and they vow to break through Yanjing City and kill all the people inside.

The Jurchen tradition of killing people has been around for a long time and will continue to do so, as exemplified by the Battle of Yashan in the last years of the Song Dynasty, the Ten Days of Yangzhou in the last years of the Ming Dynasty, and the Three Massacres of Jiading, two prosperous cosmopolitan cities that became hell on earth under their butcher's knives.

In comparison, these people killed by Zhou Yi can only be regarded as a little bit of interest.

Zhou Yi asked someone to bring a chair, sat down on the city wall, lay down, looked at the sky, this kind of life doesn't know when it will end, in fact, he doesn't like this, if he has to kill people, he hopes to go to the island of Shikoku in Kyushu, cross the Korean Peninsula from Changbai Mountain, oh no, it seems to be called Goryeo now, go to sea from that place, and soon reach that archipelago, although the people there are still subservient to the Great Song Dynasty, but the harassment of the border has never stopped, it is really annoying. Zhou Yi felt that if he led his troops to kill those people, even if all the people on the island were killed, he would not be merciful.

Although he didn't have much contact with the people in that place, thanks to the socialist education method with Chinese characteristics, his mind was deeply resistant to this place and the people in this place, and if he could have the opportunity to let their ancestors suffer once, Zhou Yi would still be happy.

Of course, this is all in the future, Zhou Yi feels that it will be at least four or five years before it can be implemented, and now the most important experience is in the two aspects of destroying Liao and Jin, the Jin Kingdom is now gaining momentum, if you don't give them some color, they will soon ride on the head of the Great Song Dynasty.

Finally, the Song army and the Jin soldiers below began to exchange fire, and Zhou Yi stuck his head out of the female wall to look down. (To be continued......)
