Yan Yu is the governor of Yong'an of Shu, Lu Kang is the governor of Xiling of Wu, the two can be regarded as neighbors, although the relationship between Wu and Shu is that they are wary of each other, but they still maintain a harmonious atmosphere on the surface, which is also the reason why the border of Wu and Shu has been peaceful for decades.

Yan Lu's meeting was purely "accidental", and the reason why it was put in quotation marks was because this accident was Yan Yu's feeling, but for Lu Kang, it had been planned for a long time. The two were hunting within their respective borders, and they were safe and sound, but unfortunately Yan Yu shot a roe deer and ran to the border of Wu, and Lu Kang sent someone to return the prey, Yan Yu was very happy, so he set up a tent at the border and drank with Lu Kang.

Because of the relationship between official affairs, the two are not strangers, but this meeting was purely a personal relationship, at that time Yan Yu and Lu Kang both drank a lot of wine, and they were full of ambition when they talked about the world.

Lu Kang provoked him with words, Yan Yu expressed his heart directly, and asserted that Jiang Wei would be defeated and Chengdu would be lost, at this time Lu Kang threw an olive branch and promised Yan Yu the position of the king of Chengdu, and the two hit it off and plotted to seize Xichuan.

Although Yan Yu is the governor of Yong'an, it is unrealistic to surrender the city directly, at least the deputy governor Luo Xian is a huge obstruction, not to mention that when it comes to surrendering to Wu, at least half of the Shu army in Yong'an City cannot be used by Yan Yu. Therefore, Yan Yu secretly discussed with Lu Kang, entered Yong'an in the name of reinforcements into Sichuan, and took advantage of the situation to attack Yong'an, and then marched into Chengdu. Therefore, Yan Yu sent a large amount of bribes to Huang Hao, moved left and right in the court, and tried his best to lobby for help from Dongwu.

Because of Zhuge Zhan's support, Yan Yu's plan went very smoothly, Yan Yu didn't spend a penny on Zhuge Zhan, but he was able to get such strong reinforcement, which really surprised him.

The next action was just as they had conspired. The Shu Han court sent Deng Liang as an envoy to Wu to ask for help, and Lu Kang led the army into Sichuan and took the opportunity to seize Yong'an. The slight mistake in this is that they underestimated Luo Xian, Luo Xian has insight into their conspiracy, but there is no evidence. After his martyrdom, he sent his son to Chengdu to report the news, so that the Shu Han court knew about the invasion of Eastern Wu in the shortest possible time.

But this is not the point, the leak is only a matter of time, without Luo Xian, the Shu court will get the news a few days late at most, anyway, the Wu army has already taken Yong'an and Jiangzhou, and it is one step away from taking Chengdu.

Therefore, in the next expedition arrangement, Yan Yu won the opportunity to command the right army. Before the battle of Qingyangpu, Yan Yu got in touch with Lu Kang, and Lu Kang instructed Yan Yu to take the initiative to withdraw from the battlefield after the battle began, and hand over the empty right wing to the Wu army, which completed the roundabout encirclement of Zhuge Zhan's army.

As for Yan Yu's defection on the battlefield, it was because Lu Kang didn't think it was necessary, anyway, the strength of the Wu army had already occupied an absolute advantage. It was more than enough to deal with the 35,000 Shu army. What's more, although Yan Yu surrendered, the entire right army may not all be single-minded. If you really want to defect, the effect may not be good.

What's more, Lu Kang has other arrangements for Yan Yu, and in the battle of Qingyangpu, Lu Kang is victorious, but he has a great appetite, and it is not just as simple as defeating the Shu army. Lu Kang wanted to completely annihilate the Shu army at Qingyangpu, completely destroy the defense force of Shu, and lay a good foundation for the next step of taking Chengdu.

In order to achieve this strategic goal, it was necessary to seize the rear base of the Shu army, Yuxian. Yunxian is not only the only way to Chengdu, but also the entire logistics base of the Shu army. All the grain and grass of the Shu army are gathered in Yun County, once Yun County is taken, it is equivalent to putting the Shu army into a desperate situation.

The situation is very favorable to Lu Kang, the Shu army in Yuxian County is not heavily garrisoned, only Zhang Zun is guarded with thousands of people, as long as Yan Yu is sent to Yuxian and the city gate is opened, Yuxian is at your fingertips, it is really not good, even if it is a strong attack, Yan Yu's men and horses are also dominant.

After the Battle of Qingyangpu began, when Zhuge Zhan was in full swing in the middle of the road, Yan Yu ordered the right army to withdraw from its position and advance in the direction of Yuxian. Many soldiers felt inexplicable, and Yan Yu claimed that the Wu army sent troops to attack Yu County, and he was ordered to return to Qi County. The soldiers of the right army all believed it, and the soldiers took obedience to orders as their duty, and they naturally obeyed Yan Yu's orders, not to mention that everyone knew the importance of Yu County, so Yan Yu's actions were undoubted.

When Yan Yu rushed back to Yu County, the city gate of Yu County was closed, which was not surprising, after all, it was in wartime, although Yu County was in the rear, it was also very well guarded. Yan Yu immediately ordered his soldiers to call the door.

Not long after, a head poked out of the city, it was the soldier Cao Shangshu Zhang Zun, Zhang Zun looked at the team under the city, glanced at Yan Yu again, and said with confusion: "Didn't General Right fight in Qingyangpu, why did he turn back to Yu County?" ”

Yan Yu said in a deep voice from afar under the city: "Zhang Shangshu, Zhuge Duhu received a secret report, saying that the Wu people sent a group of men and horses to bypass Qingyangpu and prepare to attack Yu County, so he specially ordered to come to help defend Yu County, and asked Zhang Shangshu to open the city gate and allow him to enter the city." ”

If it was someone from the side guarding the city, maybe the city gate would be opened at this moment and Yan Yu would be allowed to enter the city, after all, Yan Yu was the deputy commander of the Shu army, and there was no reason to suspect Yan Yu's other motives. But it just so happened that it was Zhang Zun who was guarding the city, Zhang Zun was Zhang Shao's nephew, and his position was naturally consistent with Zhang Shao, and Zhang Zun was extremely disgusted with Huang Hao, hating the house and Wu, so he naturally had no good impression of Huang Hao's sworn friend Yan Yu, and said unhurriedly: "There are Wu people who sneak attack Yu County?" How did I not know? What's more, I didn't receive an order from Zhuge Duhu, the right general can have a handwritten order from Zhuge Duhu, take a look. ”

Yan Yu frowned, and said: "I came down in a hurry, I just took the order of Zhuge Duhu, and I didn't take the instructions, now the military situation is urgent, the Wu people may come to attack at any time, and it is important to guard the county, and I also ask Zhang Shangshu to open the city and release it first, and I will make up the documents later." ”

At the beginning, Zhang Zun just wanted to make things difficult for Yan Yu, disgusting and disgusting him, but he didn't expect Yan Yu to really have no military order, which made Zhang Zun very puzzled, Yan Yu kept saying that Wu soldiers came to attack Yu County, but Zhang Zun looked left and right, and didn't see half of Wu Jun's figure at all, plus Yan Yu's words flickered, Zhang Zun smelled a trace of unusual smell, and it was a matter of course to close the door.

"It's not that General Right doesn't know the Han army's regulations, and those who let them go without following the orders will be punished for dereliction of duty. If the right general wants to enter the city, he only needs to take Zhuge Duhu's edict, otherwise it will be difficult to obey his fate. ”

Yan Yu was furious, and when he turned around, he wanted to order his subordinates to attack the county seat. (To be continued......)
