The Lu Bu army had already arranged the crossbow troops in the ambush area. Although the Lu Bu army was also seriously injured during the shooting of the stone thrower in the past few days, the Liu Bei army above the city was more damaged because the target of the Yangzhou army was a city, and Liu Bei could only rely on his character to shoot Lu Bu's crossbow troops or Lu Bu's camp.

This is why Liu Bei couldn't bear it anymore. Liu Bei didn't know whether the Lu Bu army stones below were enough. He only knew that if this continued, his Runan City would inevitably be unable to bear it. There were already many places on the top of the city that were sunken. The people and military morale in the city were all morale, so Liu Bei would definitely leave the city to eliminate this biggest threat.

The only thing that can quickly approach the crossbow cannons and not be discovered is the speed of the heavy armored cavalry. Lu Bu's army also knew that Liu Bei would come, so they set up an ambush. Because Liu Bei's army was fast in cavalry, Lu Bu didn't want to chase him at night, so the crossbow came in handy.

The bed crossbow has great power and can penetrate the armor of the heavy armored cavalry. The continuous shooting of the bed crossbow and its range can catch up with the high burst speed of the Western Liang Iron Cavalry.

"Swoosh swish swish!" The crossbow's shooting speed was very fast. The giant arrow vacuum formed in such a moment. Basically, no one could block the impact of the giant arrow. A giant arrow could penetrate several heavy armored cavalry.

"There are ambushes, there are ambushes, retreat quickly, retreat quickly!" Liu Bei's Xiliang Iron Cavalry General shouted loudly. He wanted to discover his robes in time to recover the losses, but everything was futile. The crossbow had already put on the bowstrings. Their heavy-armored cavalry were fast, but they could be faster than the flying arrows.

Some people were shot to death on war horses, some were turned into candied haws. The miserable ones were shot to death. Their war horses were immediately stopped halfway, and the cavalry were thrown out, and the robes that were rushing to escape were trampled on the city with meat paste.

"Three Hundred Steps?" The young man looked at the power of the crossbow over there. The three Hundred Steps were originally calculated by him, and measured by human life. He also used a stone thrower to make Shouchun's crossbow unable to fight back.

But today he saw that it was not like this, "Four Hundred Steps!" Four Hundred Steps actually have power, and this power does not decrease at all. Even without a giant shield, the thickness of the heavy armor is not fake.

"Five hundred steps! Six hundred steps." The young man felt his breathing a little rapid. "Seven hundred steps!" He said surely. Only when he reached the seven hundred steps did he not have much harm.

Seven hundred steps, and even so, those giant arrows still shot and killed several Western Liang Iron Cavalry.

The ground was covered with the bodies of the Xiliang Iron Cavalry, and the cries of those undead war horses, and the blood stained the ground red.

The young man swallowed.

"How is it!" The two guards of Lu Bu next to him looked at the young man proudly.

"Those crossbows!" They thought the young man was frightened by the scene in front of him. After all, there were bloody corpses and wailing sounds that were not dead on this big night.

But unexpectedly, the young man was still shocked just now, and his tone changed in an instant. His eyes were glowing green, making these Bingzhou Wolf Cavalry Guards beside Lu Bu feel that they are not wolves. And this young man is right.

"Those crossbows!" The young man didn't care about the corpses at all and rushed towards the crossbows over there.

He didn't care about the corpses on the ground. Even if the minced meat was stained with shoes and trousers, his legs were covered with blood, but he was still not afraid at all, as if he was walking on a muddy road.

"Oh!" These Lu Bu's guards were shocked when they watched the young man run over.

"Ahh!" The Xiliang Iron Cavalry who fell down a war horse was not dead, and he struggled to fight. The young man was indeed closest to him. He knew that he could not survive, and even if he died, he would pull a cushion. He rushed towards the young man with a ferocious look. The sword in his hand was about to wave down.

"Be careful!" Lu Bu's guards there shouted loudly, but the young man was unmoved at all, and he was about to see the sword of the Xiliang Iron Cavalry who was struggling dyingly was about to fall.

Suddenly, a small object was taken out of the young man's sleeve, and a cold light shot out from the small object. The sword that was about to fall was stopped suddenly. The Xiliang Iron Cavalry, who was struggling to death, fell down and could no longer get up.

"Is it okay!" Several guards over there ran over and asked the young man.

"It doesn't matter, you don't have to worry about me." The young man took out the object inside his sleeve, and it turned out to be a small crossbow machine.

"Who cares about you? We are afraid that you will rush over. The crossbow over there is a secret of our army. Your current task is just to look at the crossbow, not the crossbow." These guards said to the young man. Liu Mang has a strict management of the crossbow. He will not let Liu Bei or Cao Cao get it. What these guards are afraid of is that this young man encounters the crossbow.

"Okay, okay!" Although the young man's eyes were hot at this time, he was a little clearer. Bed crossbow? Let's solve the crossbow first, and then get the crossbow done later. Anyway, there is still time.

The young man nodded and ran towards the crossbow, "Let's go, take me to see your lord!" The young man said to these guards.

These guards asked the young man in confusion, "Has the problem been solved?"

"Solved!" the young man said calmly.

"Okay, let's go!" Although several guards were puzzled, they still took the young man away and arrived at Lu Bu's place.

"What? It's that simple?" Lu Bu looked at the young man in front of him with a strange look on his face.

"Yes, it's that simple." The young man waved his hand. Lu Bu covered his face and didn't know what to say. It turned out that the young man had been there for so long and finally gave the answer, which was to let Lu Bu pull the crossbow down five hundred steps, because the stone thrower designed by the young man for Liu Bei was only 500 meters in range.

"What's your idea? We don't have many stones!" said an impatient general next to him.

"There are not many stones?" The young man frowned, and he asked Lu Bu to pull the crossbow toward him. Because the crossbow can be powerful even at 500 steps. But he didn't expect that Lu Bu's army would have few stones. No wonder, high-intensity ejection in the past few days is inevitable.

"Okay!" The young man thought for a long time. "How many stones are there left?" he asked Lu Bu.

"It's only enough for half a day tomorrow." Lu Bu replied.

"Enough!" the young man nodded. "Do you have any pens or ink?" he asked Lu Bu.

"Huh?" Although Lu Bu was puzzled, he still brought pen, ink, paper and inkstone to this person.

"So this!" The young man was graffitiing randomly on the paper.

"What are you drawing? Is this the one who brushes us!"

"Slow!" Although Lu Bu on the side couldn't understand, he could see a general rack. Isn't this the general structure of a crossbow? Even the young man even drew some details inside.

"That's it, raise his elevation angle and adjust his angle, that's it. Just these angles. Just install your crossbow at a distance of 500 steps from the city wall. From my angle, you will inevitably destroy all the stone throwers on the city wall." This young man was very confident.

Lu Bu didn't understand these things, so he could only take out the drawing and give it to the launching captain.

The captain was also very strange, but when he saw the young man full of confidence, he would not say anything.

On the second day, the Yangzhou army once again appeared under the city of Runan. On the city tower, Lu Bu obviously saw that Liu Bei's face was very bad and very gloomy.

This is nothing nonsense. No matter who gets rid of thousands of heavily armored cavalry by the enemy, he will be sad. Moreover, he has not even encountered the shadow of the enemy, so Liu Bei's face looks extremely ugly today, but in order to boost morale, Liu Bei still stood on the city wall.

"Prepare to attack the city!" With Lu Bu's order, the war drums roared. The crossbows began to load huge rocks one by one.

"Lord, you go down to the city wall, it's dangerous here!" Liu Bei's gatekeeper in Runan City said to Liu Bei. The next step is the shooting of the stone thrower, and there will inevitably be huge rocks bombarding the city wall.

"No, I will live and die with Runan City today." Liu Bei said resolutely. The look on his face was admirable and the morale below increased a lot.

If possible, a genius would be willing to stay on this city wall. Liu Bei was no longer the young man who was once young. Now Liu Bei is in middle age. What he thought of was to save his life and cherish his life so that he could better conquer the world, right? You must know that Liu Bei has no descendants yet.

In addition to the reason why Liu Bei got on the city wall, the morale in Runan was too low, that is, he had already considered it in the past few days. Although the Yangzhou Army's crossbows below were bombarded with high density, they rarely hit the city tower, so the captains placed the stone thrower next to the city tower.

Liu Bei also saw this, so he led the way.

You can't say that Liu Bei's lord's effect is really good. When fighting there, the morale of the Runan army below increased greatly. The accuracy of the stone thrower increased a lot. On the contrary, the Yangzhou crossbows suddenly lost their accuracy. They had already had two rounds, and they were all shot into the city, and there were even jokes that they didn't even touch Runan City.

"Is this your method?" The sarcastic voice was beyond words.

"Hmph!" The young man snorted coldly, and he went forward in person, calibrating the angles of these crossbows. "Okay, you try again!"

"Boom!" A huge rock flew out, and at this time the huge rock was directly shot to both sides of the city tower.

The 'bang' sound shocked Liu Bei on the city tower, "What's going on!"

Someone came to report it soon. It turned out that a stone thrower was knocked down by the crossbow of Lu Bujun below.

"Don't worry, lord is just a lucky person," the captain next to comforted Liu Bei, and Liu Bei nodded because the other Yangzhou army's crossbows that were shooting together were still the same bird-like, and they were all shot very thinly.

Liu Bei felt at ease, and the young men below began to debug the crossbows one by one.

"Boom, boom, boom!" Liu Bei on the city tower finally found something was wrong, because from the beginning, one or two huge rocks fell on the city tower, which was a lucky fortune, but now one after another, bombarded the city tower, what is this? Did it fall into the pile of shit?

"Not good, no good, lord general!" A soldier ran up to the city tower in panic and shouted loudly.

"Why are you panic?" Seeing his subordinates making a fool of themselves, the city gate captain shouted a little angrily. "Didn't I tell you to be calm, calm!"

"Yes, it's the general," the soldier took a deep breath to calm his emotions. "On the general, our stone throwing machine over there has been half destroyed."

"What!" It was the captain's turn to be calm. "Say it again!"

"General, more than half of our rock-dumping aircraft have been destroyed by the enemy, and now there are only a few left."

"Okay, okay!" An excited shout suddenly came from under the city wall. The captain then felt sad and found that the few remaining stone throwers had also been destroyed. He had not had time to be sad, over there.

The sound of "Wow!" sounded.

"What's wrong, what's wrong." The earth shook, and Liu Bei was panicked. It turned out that their city tower had completely become the main target of the crossbows.

"Lord, hurry up and go down the city tower." This city tower can no longer be left, and if it flows down, it will be a dead end.

"Haha, haha!" The soldiers of Lu Bu's army below laughed loudly as they looked at Liu Bei's embarrassment on the city wall.

"Okay, now there is no stone throwing machine on the city wall, and half of the threat has been removed. It is said that our army ordered the huge rock to be shot and the entire army to attack, capture the city wall, and take down Runan!" Now Liu Bei's morale is at its lowest point. The whereabouts of the lord are unknown, and his own stone throwing machine is defeated again.

It can be said that after the last round of rock-throwing machine bombardment is completed, once the ladder is used to climb the city wall, Runan City, will almost be attacked.

"Report, report to the lord, and write to Yangzhou." A messenger suddenly rushed to Lu Bu and taught him a letter to Lu Bu.

Lu Bu picked up the letter and read it. His face was very complicated, with struggle, anger and more of a worry.

"What's wrong with lord?" Zhang Liao asked lord Lu Bu next to him.

"Wenyuan is preparing to withdraw his troops." (To be continued, please search for Astronomy, the novel is better, updated and faster!
