Cao Cao is ready to take Lu Bu under the knife, there is another important reason, he thinks that he has a good relationship with Wang Yun, and Wang Yun is now Lu Bu's chief think tank, as long as he says that Wang Yun moves, it is easy to capture Lu Bu, as long as he captures Lu Bu and takes the opportunity to integrate his troops, then he will get a combat power even above his main military force - Qingzhou Army Bingzhou elite soldiers. Thinking of the terrible iron cavalry in Bingzhou, Cao Cao even shed a little saliva. The Central Plains is fighting for hegemony and the construction of cavalry is not an overnight achievement, first, if you want to win the championship, a strong cavalry is indispensable. Think about it, how terrible it would be for thousands, or even tens of thousands, or tens of thousands of cavalry to suddenly attack, on top of a flat river? Moreover, the mobility of the cavalry is several times that of the infantry, and it can maneuver for two or three hundred miles a day, and even if the battle is unfavorable, it can safely get out of the battle and choose the opportunity to fight again. Swift, erratic cavalry can appear anywhere, attacking the enemy, leaving the enemy exhausted and overwhelmed. The elite cavalry must be the result of several years, otherwise when the alliance with Dong was formed that day, everyone would not be envious and jealous of the white horse in Gongsun Zhan's hands. Cao Cao attached great importance to the construction of cavalry, and always focused on building a cavalry that could fight for him in the world. However, he was located in the Central Plains, and his horses were far from his territory, and it was very difficult for him to obtain good horses (no one would be willing to sell their precious horses to potential enemies). Over the past few years, Cao Cao has gone through hardships, and finally established a cavalry with a number of about 3,000, called the tiger and leopard cavalry, the name is domineering, but the combat effectiveness is just the opposite, mainly because the scale is very small, Cao Cao can't afford to lose, and generally does not put it into battle, so that the battlefield experience of this army of soldiers and horses is very lacking, and another reason is that the war horses of this cavalry are he scraped together with great difficulty, there are war horses, there are ploughing horses, and there are horses for pulling carts, these horse qualifications can be described as shabby, and the problem of transportation is not big, if it is used to charge into battle, it will not be easy. And at this time, the horses, grass is just their snack, the main food is still grain, think about how much food a horse needs a day to fill the stomach? In this way, the cost of raising a cavalry can be imagined, although Cao Cao secretly appointed a captain to touch the gold to raise military salaries for him to steal graves and dig graves, but he could never make ends meet, resulting in the needs of cavalry troops often difficult to meet, and the result was that the war horses lost weight seriously and could only maintain a minimum of training. With these difficulties, Cao Cao was naturally fascinated by the fact that he could get an elite cavalry out of thin air.

Cao Cao thought that it should not be difficult to convince Wang Yun, so an enthusiastic handwritten letter was secretly handed over to Wang Yun. In the letter, Cao Cao called Wang Yun the uncle, first of all, he reviewed the past friendship between the Wang and Cao families (his father Cao Songshan and Wang Yun were officials in the same dynasty in the early years, and the two families had very close contacts, which can be described as world friends), and then thanked Wang Yun for stabbing Dong with a knife, and then praised Wang Yun for taking risks and separating Dong Zhuo and Lu Bu in order to kill the national thief, but Lu Bu has no plan, if a villain instigates it, it is very likely to harm Wang Yun. When he saw Wang Yun succumbing to Lu, he was very worried about Wang Yun's safety, and Wuyun was highly virtuous, how could he commit to him? So for the safety of Uncle Shi, in order to save the Han Emperor under Lu Bu's canine teeth, he decided to raise troops to attack Lu Bu and welcome the Son of Heaven into Yanzhou. In order to achieve great things, he begged Wang Yun to cooperate with him inside and outside, and jointly punished Lu Bu, a national thief, and he also showed that he was dedicated to the country and had no selfish heart. Wang Yun laughed when he saw the letter and secretly scolded Cao Cao for his good strategy. After several years of turmoil, Wang Yun admitted a fact - if there are no soldiers in hand, no matter how big the official is, it is just a flower in the moon and water in the mirror, think about how many officials Dong Zhuo was in Luoyang City, how many officials were cut off their heads, he can't remember, there are no three princes and nine kings in it, how about you have a high position? Provoke the people who have soldiers in their hands, and two minions can decide your life and death! He knows Cao Cao very well, that is a person who has been rated as "a capable minister in the world, a traitor in troubled times", can he be willing to give up his power? Pipe dream! betrayed Lu Bu, even if it was successful, he had no soldiers and no generals, and it was not the same as when he was under Dong Zhuo, let Cao Cao rub and tremble every day, lest he suddenly add a knife and axe. But Lu Bu is different, Lu Bu is brave and strategic, and he is the most lacking of advisers around him, coupled with the relationship between Diao Chan, he is like one person and above ten thousand people, which can be described as a high power and a proud spring breeze.

Compared with the two, Wang Yun made a choice very easily, he immediately handed Cao Cao's letter to Lu Bu, Lu Bu was furious when he saw the letter, jumped and shouted to raise troops to attack Cao Cao, but fortunately Wang Yun was persuaded by Wang Yun, Wang Yun said why not plan the plan, he pretended to cooperate with Cao Cao, and led his troops into Luoyang, and then ambushed it. Lu Bu was overjoyed and asked Wang Yun to act according to the plan.

Wang Yun immediately replied to Cao Cao, in which he told Cao Cao that in Chang'an, in order to save the emperor, he used a beauty plan to divide Dong Zhuo and Lu Bu, but he acted carelessly, and the great cause was not accomplished, so he had to flee with Lu Bu. After arriving in Luoyang, the Han Emperor was subjected to Lu Bu's every possible *, he was inexplicably sad and angry, and he had been trying to find a way to kill this thief, but he had no power to restrain the chicken, and there were no soldiers under his command to help, and Lu Bu was the first brave general in the world, unparalleled in martial arts, and tens of thousands of armor soldiers in his hands, he dared to hit the stone with an egg? Now it's okay, Cao Cao is dedicated to the Han and leads the troops to the king to save him, and he should obey and help each other with death. and made an appointment with Cao Cao to open Luoyang City to lead Cao Cao into the city......

Cao Cao was overjoyed when he received Wang Yun's reply, and immediately led the Xiahou brothers, Cao Ren, Cao Chun, Cao Hong, Le Jin and others to Luoyang with an army of 30,000, but he did not know that this was destined to be a sad journey......

On the way to lead Cao Cao's troops into Luoyang, Wang Ruixin's reinforcements had also reached thirty miles north of Dangyang City, and after joining forces with Zhang Yun, the two armies killed Dangyang City again.

Zhang Fei immediately flew off to report to Liu Zhang.

After Liu Zhang received the report, he replied to Zhang Fei that no matter what, he had to do everything possible to drag this army and horses, and he must not let them retreat to Xiangyang. At the same time, he gave Lu Su and Gan Ning an order - attack! He will not forget Gangneung, who has long been surrounded by himself. At the sound of an order, 40,000 troops launched a fierce attack on Gangneung from the southeast, northwest, and northwest, this time it was no longer a joke, he moved seriously, there were at least 20 pontoon bridges in each direction to make the Jiangling City moat useless, and the battle began in less than half an hour, and the first wave of troops boarded the Gangneung city wall.

The first to cross Gangneung City was Gao Shun. Historically, Gao Shun Lian had an elite force that did not have many troops, but had terrible combat effectiveness - trapped in the camp! Liu Zhang, who came from later generations, knew this very well, but after Gao Shun's army was defeated and surrendered, this army fell on Lu Bu, so he ordered Gao Shun to select soldiers in the whole army and rebuild the trapped camp. After more than three years of training, a new camp of 3,000 people appeared in the Yizhou army. These soldiers are all more than 1.7 meters tall, they are heavy infantry, and they are all wrapped in iron armor, and they can be seen to be extraordinary at a glance. This newly trapped camp once competed with the Yingwu Army, the strongest army in Yizhou, in the school field, and the result was that the combat strength of the newly trapped camp with the same number was not inferior to that of the British Army.

When Gao Shun led the trapped camp and began to attack the city, the defenders found that the bows and arrows in their hands were like tickling these black-armored soldiers, and the slightest hint of spark could not hinder the opponent's attack, only a huge rolling log and stone could kill these black-armored soldiers. While the defenders were busy throwing rolling logs and stones to the city, the agile soldiers in the camp had successfully stormed the city wall under the leadership of Gao Shun. With the city wall to rely on, it is not yet able to resist the trapped camp, and the protection of the city wall has been lost, and the Jingzhou army wants to repel the trapped camp, the possibility cannot be said to be none, but it is very small!

Soon after the trapping camp attacked the city wall, the barbarian army, not to be outdone, also broke through the defense of the city wall under the leadership of Zhang Liao. It needs to be explained here that there are 15,000 people in the barbarian camp, and Liu Zhang originally wanted to select one person from the barbarians as the main general, but after a long time of investigation, Liu Zhang did not find that the barbarians who could take on this important task, and it was impossible for him to hand over a unit to a mediocre person, which was irresponsible to the soldiers. So Zhang Liao was appointed by him as the general of the barbarian army, but in order to take care of the emotions of the barbarians, and in order to stabilize the morale of the army, Liu Zhang appointed many barbarians as middle and lower-level officers. Zhang Liao was one of the five good generals of Cao Wei, and his ability to lead troops was absolutely first-class in the late Han Dynasty, and under his strict training, the barbarian army also became an elite division in Yizhou. In particular, the barbarians live in a harsh environment, they have been fighting with nature since childhood, and they have survived the fittest, they have a hard-working personality and are extremely strong, which can be described as the best source of soldiers, and they can become an army with a little training.

Then the other two gates were also quickly broken under the command of Xu Huang, Yu Ban and others, and Bei Yu saw that the defeat was irretrievable, and drank dove poison and died. The defenders of the city then surrendered to Liu Zhang under the command of Han Song.

Liu Zhang immediately ordered the army to take over the city, occupy the treasury, issue a notice to reassure the people, and called on the people to go out of their homes to help the Yizhou army clean up the battlefield. The city changed the banner of the king, and the people were panicked, but no one dared to go out of their homes to help the Yizhou army clean up the battlefield. Liu Zhang was depressed in his heart, so he could only ask the troops to assist the Yizhou army in cleaning up the battlefield and counting the results.

After the clean-up, since the siege of Gangneung, the Yizhou army has suffered more than 6,200 casualties, of which 2,480 were killed in battle. The defenders of Gangneung lost 3,100 killed and 7,600 captured. Liu Zhang obtained a total of 130,000 yuan in various warehouses in Jiangling, 300 catties of gold, 700 catties of silver, a large amount of jewelry and jade, 53,000 stones of soybeans, wheat, rice, etc., and a large amount of ordnance......

The next day, Liu Zhang left behind 5,000 barbarian troops and all the wounded soldiers, and because of the ban and Wu Yi, he stayed in Jiangling and led about 30,000 troops to Dangyang.
