Sun Yu took a closer look, and more than two dozen trebuchets were pushed out of the city. Behind this pile of trebuchets stood a woman dressed as a scribe, who was at most ten ** years old, with clear eyebrows and beautiful eyes, and although she was wearing a scribe's robe, the large sleeves of the robe were cut off by her, revealing a beautiful forearm.

Looking at the style of the clothes, it was a bit like a craftsman's short clothes, Sun Yu thought about it slightly and understood, since this Liu Ye was the designer of the trebuchet, she must like to do carpentry work very much, so the wide scribe's sleeves were not conducive to doing handiwork, so she cut the sleeves. It's interesting!

The trebuchet was pushed to the place of two arrows outside Xuzhou City, such a distance ordinary archers could not shoot, Liu Ye waved his hand, and hundreds of soldiers twisted cow tendons to the trebuchet and put stones in the big scoop.

Sun Yu thought to himself: There is no science such as ballistics in this era, and the accuracy of trebuchets should be very poor. As long as the soldiers in the city shrank their heads and hid behind cover, the trebuchet was useless.

However, Sun Yu thought wrong again, only to see that after Cao Jun prepared the trebuchet, Liu Ye let out a burst of crisp laughter, she waved her hands, and a blue light suddenly rose on her body, and two blue characters jumped on the top of her head "Thunderbolt". Liu Ye stretched out his hand to the position where Tao Qian was standing, and shouted: "Launch!" ”

"Thunderbolt" is an extremely rare martial arts technique of the control system, which can be used to indulge a specific instrument, that is, a thunderbolt car.

The dozens of trebuchets actually rotated automatically under Liu Ye's command, as if someone was indulging, turned their heads and aimed at Tao Qian, and then only heard a few loud noises of "collapse", the tendons were loosened, the big scoop on the trebuchet was raised, and dozens of boulders were thrown from the big scoop, flying over the land of two arrows, and smashed towards Tao Qian's head accurately.

I rub! Sun Yu jumped up suddenly, it's too unscientific, this martial arts skill can actually be used in machinery, what kind of mess is this, this is more ballistics than ballistics! His figure flashed, rushed to Tao Qian's side, grabbed Tao Qian, and dragged her away from the place.

After only hearing a "boom" sound, the dust scattered, and the place where Tao Qian was standing just now had been smashed out of a huge pit by dozens of big stones, and the big stones collided together, and exploded out a number of scattered small gravels, which made the Xuzhou soldiers next to him hold their heads and run away. A small stone hit Sun Yu's back, but fortunately Sun Yu was wearing a set of silver armor, otherwise it would have hurt a lot.

The civil and military officials in Xuzhou only felt cold and fainted...... It's too much!

Cao Ying, who was outside the city, laughed and ordered the soldiers to shout in unison: "Tao Qian's old man still doesn't surrender?" In a moment, I will ask the soldiers to build a hundred more thunderbolts, and they will fly all over the sky and smash your head full of bags. "She only brought more than 20 thunderbolt cars with her to Xuzhou this time, but she could call the soldiers to cut down wood at any time to make it, and it is not a problem to build dozens or hundreds of them.

At this time, the first round of stone throwing was over, and the Cao soldiers began to twist the cow tendons and move the stones again. Although the Thunderbolt is very powerful, the disadvantage is that it takes a long time to reload ammunition once and it is impossible to fire continuously and continuously.

Sun Yu seized this gap and let NM01 calculate, although Liu Ye and her trebuchet stood two arrows away, ordinary bows and arrows could not shoot so far, but Sun Yu's five-stone big bow could shoot this distance. Sneaking up on Liu Ye with an arrow, so that she couldn't let go of the "thunderbolt", Sun Yu made up his mind, hid behind a battle grid on the city wall, and secretly aimed at Liu Ye from the grid.

Hey! One more step to the left, uh-huh! Yes, from behind the two soldiers. A little bit to the left, hey, the lock is successful. Sun Yu's right hand loosened, and there was a "buzz" sound, and the five-stone big bow sent a wolf iron arrow towards Liu Ye in the distance. Of course, Sun Yu didn't want to tear his face with Cao Ying, so this arrow didn't want Liu Ye's surname, but just went to her shoulder.

This arrow flew extremely fast, and ordinary people couldn't see it clearly with the naked eye, after all, the power of the five-stone big bow was enough to crack the stone, so the arrow shot out was like a meteor catching the moon.

Seeing that the arrow was about to be inserted into Liu Ye's shoulder, a halberd carrying golden light suddenly stretched out next to him.

"Smack!" The arrow was intercepted in mid-air by the halberd, and immediately fell into the dust.

Dian Wei's body flashed with golden light, and the word "evil" was protected in front of Liu Ye on his head, and he roared loudly: "Sun Yu, you villain, I guessed that you were going to plot against Lord Liu." ”

I'm depressed! Sun Yu frowned, and at this time, another general came out of the Cao army, carrying a longbow, slim and elegant, it was a young beauty of about eighteen years old, this woman Sun Yu had seen before the Tiger Prison Pass, it was the "Bow King" Xiahou Yuan. I only heard Xiahou Yuan say loudly: "Sun Xunzhen, return my sister Xiahoudun to me!" ”

She took the longbow from her back with her backhand, aimed at Sun Yu, and "brushed" a chain of three arrows, and the arrows all came with golden light. Sun Yu smiled bitterly, and his body also flashed with golden light, showing the word "Bow King", "brushing and brushing" returned three arrows, and the six powerful arrows collided in mid-air and fell together, and no one took advantage of anyone.

The fake "Bow King" faced the real "Bow King", and the result was half a catty and eight taels. Xiahou Yuan stomped his feet! Sun Yu was depressed for a while, there are too many capable people in Cao Ying's army, and super monsters are emerging in endlessly, even if I catch Xiahoudun and Yu Ban by fraud? There is no bloodthirsty Lori, and there is also the "evil" Euphorbia Lori. If there is no bower, there will be another bow king. The Cao family is worthy of being the strongest family in the Three Kingdoms, which makes people want to cry without tears, who is not good, why should I provoke Mimiyan.

At this time, the ammunition on the thunderbolt car had been loaded, Liu Ye stretched out his hand to the gate of Xuzhou City, and more than 20 boulders roared towards the city gate, only a few terrifying "boom boom" sounds were heard, and the ancient and majestic gate of Xuzhou made a tooth-sore buzzing sound, obviously choked by the stone.

I'll it, after a day like this, the city gate will definitely be smashed. Fortunately, Cao Jun did not have many thunderbolts, and if Cao Jun had hundreds of thunderbolts, it was unclear whether the Xuzhou City Gate could support it for half a day. Once the city gate was smashed open, Cao Jun poured in, relying on Dian Wei, Xiahou Yuan, Cao Ren, Cao Hong, Le Jin, and Li Dian...... Those large number of monsters are supplemented by Cao Ying's general skills, where can Xuzhou City last for a long time, relying on himself and Xu Huang, they can't stop so many generals at all.

Sun Yu shouted: "Move stones, block the city gate!" ”

The people in Xuzhou woke up, they were scared stupid by the thunderbolt, they didn't react for a while, and they were woken up by Sun Yu before they remembered that the city gate was dangerous, and the major generals hurriedly ordered their soldiers to transport the big stones prepared in the city to the back of the city gate, and stuffed the city gate hole from the inside, so that after dealing with it, even if the city gate was smashed, the enemy army could not enter the city.

Liu Ye commanded the thunderbolt car, bombarding the city gate one after another, just like this from morning to noon, and from noon to afternoon, the ancient Xuzhou West Gate finally could not withstand the continuous bombardment, a huge crack appeared, and the city gate was shattered into sawdust. Cao Jun was overjoyed and was about to rush inside, but when he saw it, the door hole was full of stones, and he didn't know how thick it was. Sun Yu had already ordered people to block the city gate from the inside, piled up stones, and stuffed them in the cracks of the stones with earth, which was very strong.

"Wow, Sun Yu, you are so shameless, you blocked yourself to death, and you fought like this?" Cao Ying was so angry that she jumped to her feet, and she instructed Xiahou Yuan to shoot a letter into Xuzhou City, which read: "You are the behavior of a turtle with a shrunken head, don't you know the truth that it is necessary to rob the village to defend the city?" The war book says that the defending side has to often go out of the city to harass the enemy, and there is no reason to block their own doors. ”

cough, I haven't read the book of war, what is necessary to rob the city to defend the city, I don't understand! I just know that when I shrunk my head turtle, you bite me? Sun Yu snorted a few times, too lazy to pay attention to her.

Cao Ying saw that Xuzhou had even done a job of blocking the city gate, and he was sweating in his heart, and ordered the troops to be collected: "Suspend the siege of the city today, the whole army is desperately trying to make thunderbolts, and tomorrow we will use hundreds of thunderbolts to bombard the city wall, hum, I don't believe that Xuzhou can still stuff the city wall." ”

Cao Ying's order, Cao's army temporarily stopped the offensive, and tens of thousands of soldiers cut down trees together, it is really not easy to be a soldier in these years, pick up a knife and gun to fight, pick up an ax and have to do carpentry. Under Liu Ye's guidance, tens of thousands of soldiers were busy with hammers and saws.

Seeing Cao Jun in full swing engaged in infrastructure construction work, Sun Yu's brows also wrinkled into a line, although he had not learned any art of war, he also knew that it was unscientific to block himself into a turtle. Now the situation in Xuzhou is that it can only be defended, not attacked. Although the Cao army couldn't get in when the city gate was blocked, the Xuzhou army couldn't get out, and it was impossible to do some night raids or something.

This is called standing in the invincible place! Wait until tomorrow or the day after tomorrow, Cao Jun will build a thunderbolt car and bombard the city wall together under the command of Liu Ye, and the city wall of Xuzhou City may not be able to hold out for long.

If you want to carry Cao Ying and drag the time to the three sisters in Taoyuan to come to the rescue, you must deal with Liu Ye's thunderbolt, but you can't go out of the city, and even if you go out of the city, you can't beat Dian Wei and Xiahou Yuan's bunch of generals, which means that you can only fight against the thunderbolt in the city...... Is there any way to do it?

Ultimately...... It's still a question of range.

Sun Yu's heart moved, isn't it just a catapult? The enemy army can build it, and our army can also build it, and the technical difficulty of the trebuchet is very small, and it is very simple to build it. The big problem is...... No one on this side knows how to use trebuchets, unlike Cao Ying, who has a Liu Ye on his side, who can use perverted martial arts skills to do it.

Sun Yu's mind moved, it doesn't matter if he doesn't use it, let nm01 command, I will personally adjust the firing angle of the trebuchet for aiming, as long as I take advantage of Cao Jun's unpreparedness, I can smash the opponent's trebuchet in one fell swoop.

Thinking of this, Sun Yu was overjoyed in his heart, and shouted at Tao Qian: "Master Tao, I have a plan, let's also make a thunderbolt!" ”
