A siege war can be said to be one of the most tragic wars, and it is also the war that tests the will of both sides of the war, especially in ancient times when there was no gunpowder and artillery. A siege battle of several years or months is like a mill of fire and meat, grinding up every living life.

The leader of an army of the Huns has absolute control over his army, and sometimes even the emperor's orders will not be obeyed, not to mention that his leader is the father of an only son who has just died. None of the generals under Hu Yanyan dared to persuade the somewhat crazy Hu Yanyan, and they had no doubt that if they objected at the slightest, they would be executed by Hu Yanyan.

For the first siege of the city, Huyanyan sent an army of 20,000 and launched an offensive from three directions, and obtained most of the Huns in Sili Prefecture with siege weapons that were not inferior to the Han people. After continuous blows for an hour, the stone bullets at the head of Zhongyang City flew wildly, and if you didn't pay attention to it, you would die, Chu Yun hid in the city cave with the iron-blooded army, holding a shield and door panel to endure passive beating. This is the first time Chu Yun has been so passive.

However, the stone-throwing trucks and ballistas of this era were unstable, and sometimes dozens of stone bullets did not necessarily hit the city wall, and even if they did, they might not be able to kill people. But this feeling of passivity is a great blow to the momentum of the defending side.

An hour's long-range strike, the Iron Blood Army only killed and wounded less than a hundred people, but everyone felt that life was like a year, Hu Yanyan did not give the Iron Blood Army any respite, and the 20,000 army accompanied by more than a dozen siege vehicles launched an attack from three directions.

The siege is all about the siege of three and missing one, this is to make the defending side feel that they can escape, so that they lose the courage to fight against the water, but if the defending side really escapes, then what awaits them must be a trap, and then defeat miserably. Hu Yanyan deployed fifteen thousand cavalry to the north of Zhongyang City, and if the iron-blooded army really abandoned the city, then they would die faster.

Chu Yun personally led two thousand to defend the east gate of Zhongyang City, which was also a frontal battlefield, Hu Yanyan sent 10,000 troops to attack this side, while Ma Hui and a military master defended the south and west respectively, they each had 1,500 men under their command, facing more than 5,000 enemy troops.

In addition, Chu Yun kept 2,000 infantry and nearly 600 iron-blooded cavalry as reserves, and the two sides fell into a fierce fight at the beginning. The iron-blooded army first used bows and arrows, wood, and stones to consume the enemy, and the corpses of the Huns were densely spread under the city, but they could not stop the fierce and aggressive Huns.

Finally, after hundreds of dead and wounded, the Huns' siege vehicles came under the city wall, the Huns have two kinds of siege vehicles, one with a battering ram, which is pushed by soldiers and relies on the impact force to hit the city gate, this one has no threat to the iron-blooded army, because several gates of Zhongyang City are blocked, except for the north gate, the rest are blocked tightly, not to mention the siege vehicle, even if it is a cannonball, it is difficult to blast open. But the other one is very threatening, this one is like a movable house, almost half as high as the wall of Zhongyang City, in the shape of a spire wooden house, extremely strong, with four wheels underneath, and it is also pushed by manpower. The outside is covered with cowhide, and the inside is a layer of iron, so that the arrows cannot be hit at all, and even the stones are difficult to damage. And the outside of the siege vehicles was splashed with mud, and the fire attack did not work.

The Huns could easily capture the city through siege engines, and if it continued like this, then the Iron Army would definitely collapse first. Chu Yun immediately discovered the danger, and he quickly jumped off the city wall directly with a long lance, which frightened everyone. Chu Yun quickly ran towards the nearest siege vehicle, the Hun army immediately killed Chu Yun, the long lance continued to harvest the lives of the Huns, and finally Chu Yun came to the front of the siege vehicle, Chu Yun threw out the long lance more than three meters long, the siege vehicle fell to the ground, and dozens of soldiers inside fell out, how could Chu Yun be polite, after Chu Yun killed these dozens of people, there were already hundreds of Huns who fed him, Chu Yun didn't dare to stay longer, he quickly ran to the city wall, and the long lance flew up as soon as he held it. This scene greatly boosted the morale of the Iron and Blood Army, Chu Yun destroyed six of them with the same means, and the Huns on the eastern city wall attacked for a moment.

In addition to siege vehicles, siege equipment such as cloud ladders are very unstable and easy to destroy, Chu Yun saw that the east side had stabilized, and quickly rushed to the other two sides.

Hu Yanyan, who was fighting outside the kilometer, and several leading generals all had ugly faces, Chu Yun's behavior just now explained what it means to be a peerless fierce general, none of them expected that such a small city would be so tenacious, and there would be such a fierce general inside.

They are all high-ranking generals of the Huns, of course they know the existence of the Divine Stone, and they also know the existence of the Divine Power Derivative, but even if they are Divine Power Derivatives, they do not have such strong strength, not to mention that the Han people in front of them are not Divine Power Derivatives at all, many of them are Divine Power Derivatives, how can they not see the true situation of Chu Yun.

Hu Yanyan's expression was solemn, Chu Yun's appearance made him feel threatened, but he didn't believe that under his 80,000 army, Chu Yun could still turn the sky upside down. He called several of the guards sent to him by the Xiongnu Emperor Liu Cong, bowed down and commanded. Several of the guards were the Hun warriors canonized by Liu Cong's parents, they were not afraid of death, and when they heard Hu Yanyan's order, they excitedly went to the front line.

Chu Yun had already cleaned up the siege engines in the east and south, he was very tired, after all, with such a high-intensity battle, he was just a martial artist, not an immortal. Chu Yun didn't use the piece of divine stone that he got from Shi Hu, the main reason was that the method he got was too weird, and it was given to him by a person who saved his enemy, no matter how he looked at it, it looked like there was a conspiracy.

Chu Yun endured the temptation of the divine stone and chose to wait, but he didn't expect that he would be so unlucky and besieged by tens of thousands of troops. In any case, Chu Yun was ready to get rid of the siege engine that posed the greatest threat to the city first, and he believed that Zhang Tong would come to his rescue.

"The last two. "The Huns' offensive did not give up because the siege vehicles were damaged, but because of the damage to the siege vehicles, their attacks were much less threatening, which is also true, and thanks to Chu Yun's lifeless destruction.

Looking at the last two siege vehicles, Chu Yun's sore arms walked over with dozens of catties of long lances, he was not ready to jump off the city wall, he was afraid of jumping down, facing the siege of the other party, he might not be able to escape back.

A few Huns who attacked the city wall rushed towards Chu Yun, Chu Yun drew the sword at his waist and killed these people lightly.

"Ha", Chu Yun shouted and waved out the long lance, the upper part of the wooden siege vehicle was shattered, Chu Yun sat directly on the ground tiredly, the long lance was placed at his feet, and more than a dozen guards surrounded Chu Yun in the middle.

After resting for a few minutes, Chu Yun stood up, the more he rested, the more tired he became, he was going to kill the last siege vehicle, so that the biggest threat to Zhongyang City would not exist, and Chu Yun would also be able to hand over the task of defending the city to Ma Hui and go and rest by himself.

The battle has lasted all morning, although three or four thousand Huns fell under the central city, but the Iron Blood Army at least a few hundred people were killed and wounded, of course, this is because the siege vehicles are too sharp, and people are constantly attacking the city wall, otherwise with the full preparation of the Iron and Blood Army, the casualty ratio will be at least ten to one.

The six-meter-high city wall was a fortified city in this era, and the Huns were not good at attacking cities, Chu Yun was completely confident that he would kill the Huns in large numbers and give his cavalry a chance. Chu Yun walked towards the last siege vehicle, far beyond the strength of ordinary people, and the long lance in his hand, which was a foot long, allowed Chu Yun to easily destroy one siege vehicle after another, Chu Yun did not encounter a single obstacle, plus he was physically and mentally exhausted, so he did not find anything abnormal.

Just when he came to the front of the siege vehicle, and the long lance in his hand waved out, four Hun soldiers came out of the siege vehicle, Chu Yun was shocked, these people turned out to be divine power derivatives, although the strength is not very high, but you must know that you are now at the end of the crossbow. Excessive exhaustion made him lose his vigilance, and the long lance in his hand was too late to be retracted, and was dragged by two of the Huns, Chu Yun tried, but did not take it back, so he could only let go.

He drew his long sword from his waist, because the other two people had already killed towards the city, and more than a dozen of his personal guards rushed over without fear of death, but they were all ordinary people, and they were no opponents at all against the two divine power derivatives, but they still bought time for Chu Yun. Chu Yun will not waste the painstaking efforts of your personal guard, he sorted out his breath and prepared to fight back.

The strength of these people is not very strong, but in the eyes of ordinary people, they can be regarded as fierce generals, if it weren't for Chu Yun's consumption today, he would be able to easily kill a few people.

A guard saw the opportunity to save the waist of one of the Huns, and the Hun stabbed him backwards with a sword, and was stabbing the guard in the abdomen, but the guard gritted his teeth and held the Hun and refused to let go. The Huns were also furious, constantly stabbing back with their swords, and this guard didn't know how many swords he had hit, and his intestines were leaking out, but he still refused to let go.

Chu Yun was waiting for this kind of opportunity, his feet walked towards the Huns strangely and rhythmically, if someone drew his footprints, then it could be seen that his steps were the appearance of the Big Dipper.

This was Chu Yun's seven-star step, the speed was extremely fast, and he came to the side of the Huns who were still trying to break free from the arms of his own guards, and the stainless steel sword in his hand ghostly went up. The Hun was startled when he saw Chu Yun coming, he hurriedly moved his sword to resist, but his sword was only blocking the afterimage, the sword in Chu Yun's hand disappeared, and by the time the Huns felt the pain, it was already too late, and his head rolled to the ground, obviously fatal by Chu Yun's blow. And the personal guard, who had won the opportunity for Chu Yun, saw this scene, with a happy smile on his face, and finally fell to the ground.

Chu Yun kept this guard in his heart, and after he got out of danger, he would definitely be buried thickly. Another Hun who had killed the city wall had already killed several of the guards around him, and he did not expect his companion to be killed so easily. And the other two companions, because of the battle with Chu Yun for the long lance fell out of the city, it was not so simple for them to come up again, the soldiers on Zhongyang City greeted with fire oil, even if it was two divine power derivatives, it was impossible for them to come to the city wall easily.

This Hun warrior felt that he was not safe here, so he immediately took out a long whip from his bosom and threw it at his companions under the city, as long as the two of them came up, then he would not worry about this Han warrior.

Chu Yun didn't move, let a divine power derivative under the city grab the whip, the Huns on the city wall were overjoyed, and pulled back with all their might, and the Huns under the city were dragged into the air, as long as a few breaths of time, he could join his companions on the city wall, and when they gathered the strength of the three people, they didn't believe that they couldn't kill the Han man.

Suddenly, a longbow appeared in front of him, and the Huns, who were in mid-air, had no choice but to let go of the whip, holding the knife in both hands and knocking away the long arrow aimed at him, but the violent force of the shock made him bounce out of the city wall.

How could Chu Yun let go of this opportunity, the longbow in his hand actually shot out three arrows in a row, and the Hun warriors in the air shot one away, but the other two could not be avoided, one shot at his thigh and one shot at his chest. The Hun warriors who fell to the ground spurted out a mouthful of blood, and then fainted, not knowing whether they were dead or alive.

Seeing the death of his companions, the Hun warriors on the city wall became angry, and at this time, there were already dozens of people around Chu Yun, but he didn't care. The Hun warrior wrapped the long whip in his hand around his waist and rushed over with a huge hammer himself. Chu Yun shot four arrows, which made him even more tired, the longbow just now was an eight-stone bow, and in order to shoot the enemy, he had to use it continuously. But these are all worth it, on the city wall, because several Hun divine power derivatives have accidents one after another, morale has dropped greatly, a small part of them have been driven off the city wall, and more have been killed by the Iron Blood Army. Now that the Iron Blood Army has an absolute advantage, Chu Yun handed over the bow and arrow to one of the guards beside him, turned around and left.

Dozens of archers fired arrows at the rushing Hun warrior, who was constantly wielding a sledgehammer and trying to block the arrows, but this was just wishful thinking. He was shot dozens of arrows, but he was really brave, he didn't stop his steps, he shouted loudly in Xiongnu to not let Chu Yun leave, but how could Chu Yun take care of him, another round of volleys, the Hun warriors finally fell to the ground unwillingly, and before dying, he threw the giant hammer at Chu Yun with all his might. Chu Yun didn't even look back and continued to walk forward, and the hammer fell to the ground with a loud noise. This person's body quickly turned into a bloodstone, and it was personally sent to Chu Yun by Ma Hui and the bloodstone turned into by the first Hun warrior killed by Chu Yun.

At this point, Huyanyan's first attack failed, and the Huns left more than 5,000 corpses and slowly retreated, and the most sad thing for him was that nearly twenty siege engines were damaged, which was almost all his inventory, and this thing could not be made in a moment and a half. In addition, the four divine power derivatives sent by Liu Cong to protect him, two died, one was seriously injured, and only one ran back with Chu Yun's long lance, these people were Liu Cong's personal guards, how could he explain to Liu Cong when the time came? In addition, he found that although Zhongyang City was not a giant city like Luoyang Chang'an, it was also a strong city, and he couldn't believe how the Jin Dynasty court had such strength. If it weren't for the people of the Chang'an Imperial Court, then which side of the army was Zhongyang City? He didn't get any information, which made him very dissatisfied with the domestic intelligence system, and the Huns also had a special intelligence system, but with their invincibility, they were no longer taken seriously, and Hu Yanyan would definitely go back and ask Liu Cong to recover.

In fact, the losses of the Iron Blood Army on Zhongyang City were also very large, close to 1,600 casualties, so that the Iron Blood Army lost nearly one-fifth, but there were hundreds of lightly wounded among them, and they could go to the battlefield again after a few days of rest, and when the Huns' attack was over, it was already afternoon. Chu Yun felt that Zhang Tong should have almost arrived at the battlefield, but Chu Yun didn't want them to go head-to-head with the Huns, and it was best to wait until Zhongyang City completely exhausted the morale of the Huns, and the cavalry suddenly attacked, so as to achieve greater results, otherwise it was likely to be a war of attrition, which Chu Yun did not want to see, and only hoped that Zhang Tong could have a good relationship with him.

Chu Yun's conjecture was not wrong, half an hour ago, the cavalry commanded by Zhang Tong arrived a few miles away from the north gate of Zhongyang City, Fang Dashan and the others wanted to immediately send troops to rescue Chu Yun, but they were all forcibly suppressed by Zhang Tong. Zhang Tong sent out hundreds of scouts to reconcoitrate the enemy's situation, and these scouts of the iron-blooded cavalry quickly got accurate information.

The Huns had a total of about 80,000 troops, including 60,000 soldiers and 20,000 auxiliaries, and among the 60,000 soldiers, there were 20,000 Janissaries of the most elite Huns. He also thought for a moment that Shangdang County must have been attacked, but they were unlucky, they encountered the main force of the Huns, and Chu Yun's decision to order Shangdang County not to rescue was correct. He just lamented the importance of the Huns to their iron-blooded army, but he couldn't have imagined that the target of these Huns was Liu Kun, and they just happened to meet.

The arrival of the cavalry of the Iron Blood Army, of course, could not escape the eyes of the Huns, although it is not known how many reinforcements the Iron Blood Army had, but they have already arrived, this is a fact.

Hu Yanyan received the news of the other party's reinforcements as soon as possible, and after receiving this news, he was not only not worried but overjoyed, if these reinforcements were defeated, then the morale of Zhongyang City would be greatly hit, and when the time came, this difficult bone might be much easier to handle.

However, what made Hu Yanyan angry was that his scouts had killed dozens of people, and he hadn't even found out how many people there were on the other side, which made him furious, and executed the three scout captains who had fled back, but when he sent someone to investigate again, the other party's people disappeared without a trace.

Zhang Tong led a large army, from the north to the southeast, the inhabitants here were forcibly relocated, the vegetation here is dense, barely able to hide the 12,000 army, but if the other party expands the scope of search, they can still be found.

Zhang Tong caught a lot of prisoners, from these prisoners, he got first-hand information, his own governor withstood the other party's attack, and killed a large number of living forces, now Zhongyang City is very stable, which gives Zhang Tong time, let him find the enemy's flaws.

A disappearance of reinforcements gave Hu Yanyan a big headache, so he had to send a large number of people to find it, and he also had to send a part of his troops to defend the Chinese army camp, which made his forces to attack Zhongyang City stretched.

However, no matter what difficulties he encountered, even if he disobeyed orders, he was ready to break through Zhongyang City, kill all the people inside, and bury his son, and the next morning, the replenished army of 20,000 was ready to launch the second siege battle again.
