PS：

"Someone to do it for you? 1 Zhuge Jin frowned, he didn't suspect that Pang Yuan was talking big, but he didn't quite understand what method Pang Yuan was talking about, so he was a little confused and unwilling.

Fa Zheng's eyes lit up, and he couldn't help but say: "What the huge man said is Hanzhong 1."

"Hehe, exactly 1

"Hanzhong? 1 Zhuge Jin said in surprise: "I understand that Hanzhong and Cao Cao do not border, could it be that they are giving up Xicheng?" １

At this moment, everyone was stunned, and took the initiative to give up Xicheng, how much courage does it take to think of it!

The corners of Liu Bei's mouth twitched, although he felt uncomfortable, he still believed that Pang Yuan was definitely not talking nonsense, but it made sense.

"What do you mean by that?"

Pang Yuan glanced at Liu Bei, whose face was a little dark, and said unhurriedly: "My lord, what is the benefit of Xicheng to me?" ”

"This Xicheng is the flank of the mediocre, if the western city is lost, the mediocre"

"My lord," Pang Yuan interrupted Liu Bei's words very impolitely: "There are still rivers and mountains between Shangyong and Xicheng, is it really Shangyong's flank?" ”

"This is Xicheng, the gateway to Hanzhong"

"Hehe, exactly, Xicheng is the gateway to Hanzhong, if Cao Cao gets Xicheng, he will definitely want to enter Hanzhong, with Hanzhong, Cao Cao can flank our army on both sides, at least to encircle our army, and even attack Sima Fang from the side, such a good place. Cao Cao wouldn't have wanted it. ”

"In that case, why does Fuqing still give up Xicheng, isn't this a self-destruction of the Great Wall?"

"Huh. The subordinates only said that Cao Cao wanted to take Hanzhong, not that Cao Cao would definitely take Hanzhong, at least we didn't agree, Sima Fang didn't agree, Zhang Liang didn't agree, if we encourage Zhang Liang and Cao Cao to fight against each other, then is it the most beneficial to our army? ”

"I see1

Liu Bei suddenly realized that Pang Yuan's idea could be said to be quite ingenious. If it can really evolve into the situation that Pang Yuan said, then it is a good thing that kills multiple birds with one stone, first consuming Zhang Liang and Cao Cao. Secondly, it can also transfer the contradiction between Zhang Liang and Shuzhong, and finally, it can also put a large number of troops drawn from Xicheng into the south, which greatly accelerates the speed of developing southern Shu.

The idea is wonderful. But

"Revenge. What if Cao Cao just ate Xicheng and formed an alliance with Zhang Liang instead? ”

"This is impossible, Zhang Liang and Cao Cao's alliance will not get any benefits, on the contrary, it may also attract the attack of our army and Sima Fang, on the contrary, if Zhang Liang and our army and Sima Fang form an alliance, it can eliminate the pressure from the north and south, and only need to face one enemy in the east. This choice is something that a normal person can make. ”

But what if the two sides are all right? This will not have the desired effect. ”

"Not bad. This choice of peace and quiet is very likely to appear, but, even so, we still get benefits, first of all, Xicheng is a useless place for us, except for fighting is fighting, drawing out Xicheng's army to attack Shunan, the gains and losses are self-evident; Secondly, the Cao army's control of Xicheng will expose the back line from Nanxiang to Xicheng in front of our army, which also provides Shangyong's troops and Yiren with fighters to consume Cao's army; In the end, it is not enough to suppress Zhang Liang's development momentum and make him have to cooperate with us honestly? ”

Everyone nodded one after another, but this was enough, Pang Yuan didn't say that everyone didn't think about it, now that he thinks about it, Xicheng is definitely a chicken rib, and it is useless at all, on the contrary, he also blocked the disaster for Zhang Liang

Cao Cao was still very puzzled by Liu Beijun's sudden withdrawal of troops from Xicheng, is this a trap?

However, the news soon came one after another, Liu Bei began a large-scale southward battle, along the Lushui and Baishui rivers south to Yuewang County and Zhuti County, opened the curtain on the development of southern Shu, which made the suspicious Cao Cao relieved his heart, and at the same time gave birth to the idea of taking the opportunity to seize Xicheng.

Xicheng itself has little value, and there is not much arable land, but Xicheng is a passage from the east road to Hanzhong, if you can use Xicheng as a springboard to take Hanzhong in one fell swoop, then Cao Cao's bad strategic situation will be immediately alleviated, and it is even possible to go south to Shuzhong and north out of Yongzhou, and the strategic situation will immediately become active.

There is no reason why Cao Cao can't see such a big benefit, and there is no reason not to fight for it when he sees it, of course, Cao Cao and Xi Zhicai can also see that it is not easy to attack Hanzhong, but there is no reason to let go of this possibility, at least take Xicheng first, which must not hurt, and then according to the specific situation, it is not too late to decide the attitude towards Hanzhong.

Cao Cao soon mobilized the frustrated army to advance westward, although the road to the west was not easy to walk, and Liu Bei's army defended the military fortress, but the disadvantages of a large number of withdrawn troops soon became apparent, although Liu Beijun was very tenacious, and even a large number of aliens went deep into the mountains to harass and destroy, but Frustrated Zhu still quickly took the Yangxian fortress.

Then the two sides fought around Mulan Sai, although the battle was fierce, but both sides did not invest many troops, Liu Beijun because there were not many troops, and Cao Jun because of the internal terrain It is impossible to invest too much combat power, and the two sides are purely fighting a war of attrition.

During this period, the alien was very brilliant, and made a mess of the logistics channel of the frustrated professor, which made the frustrated professor have a headache, and he had to mobilize Liang Xing's cavalry to guard the logistics channel, just like that, the loss of logistics was still very serious.

Fortunately, Liu Beijun's number determined that the war could not last long, and soon after, Liu Beijun finally took the initiative to give up Mulan Sai and stick to Xicheng, entering the siege stage, but it was easier to fight, because the space under Xicheng was much larger, and with the help of Yiren, in less than ten days, Fu Zhu took Xicheng.

At the beginning of July of the 14th year of Guangxi, Xicheng changed hands, Cao Cao's troops soon appeared around Shiquan, Liu Beijun retreated to Wanyuan to occupy favorable terrain to build a fortress, and Zhang Liang was also very nervous to increase troops to Shiquan.

Xiangyang Xiangfu study. Cao Cao is studying the situation in Xicheng with Xi Zhicai and others, and is planning for the follow-up strategy.

"My lord, we know the importance of Hanzhong. Liu Bei and Sima Fang would not not know that if our army attacked Hanzhong head-on, these two would definitely vigorously support Zhang Liang, and even send troops to flank our army to contain the frontal battlefield, so it was really not easy to attack Hanzhong, and they should think of other strategies. ”

Xi Zhicai's attitude is very distinct. That is, we cannot attack Hanzhong head-on on a large scale, and we can only use other methods to plot Hanzhong.

Cao Cao stroked his beard and nodded noncommittally, frowning tightly. This is a great opportunity, the status of Hanzhong is too important, but as Xi Zhicai said, if a big war is formed in Hanzhong. That's not what Cao Cao wants to see right now. After all, there is still a Yuan Shao in the east!

Cao Cao naturally wanted to use the smallest possible price to try to take Hanzhong without alarming Liu Bei and Sima Fang, but this idea was impossible.

"I don't know if I can persuade Zhang Liang to take the initiative to give up Hanzhong, from Zhang Liang's point of view, Hanzhong should not be able to hold, so they will actively develop in the direction of Wudu and Yinping, if Hanzhong is given to our army, our army will face Liu Bei and Sima Fang. will definitely not continue to pursue Zhang Liang to the west, and will even support Zhang Liang."

Xi Zhicai smiled and shook his head. Yan Xiang's idea is to take it for granted, Jiang Hanzhong gave up to Cao Cao, although he could get an ally, but he had two more enemies, on the contrary, if he fought against Cao Cao, not only would he not lose Hanzhong, but he could also have two more allies, and normal people would choose it.

Cao Cao also shook his head: "This is unlikely, or we can only use more special means to find an opportunity to take Shiquan and Nancheng in one fell swoop, and then attack Hanzhong with lightning speed, it is possible to fully achieve the goal of our army, otherwise it may evolve into a big war that is unfavorable to our army." ”

Xi Zhicai nodded: "The low-intensity war that the lord said is not to use strangers?" ”

"Well, the infiltration of the aliens and small forces, slowly smuggling the troops into place, and then launching a thunderous blow, maybe only this method is worth trying, if it doesn't go well, you can also try to take Shiquan first, and then use Shiquan's location to block a possible counterattack, and then talk about other things."

Xi Zhicai thought about it, it seems that it can only be like this now, but there is only one chance, so you should be more fully prepared, and at the same time, you should paralyze Zhang Liang.

"Lord, you can send a messenger to make peace with Zhang Liang first, and at the same time order Fu to train in mountain combat, as for the aliens, you can infiltrate the opposite side first, on the one hand, you can be familiar with the terrain, and on the other hand, you can also make an illusion."

Cao Cao stroked his beard and smiled: "Zhicai's strategy is exquisite, the opportunity is rare, we must try our best to create conditions, make full preparations, mountain warfare is indeed our weakness, this has been exposed in the previous war, and it is also necessary to take this opportunity to train." As for the messenger, haha, this is good, let's arrange this as soon as possible. ”

"One more question, my lord."

Cao Cao paused for a moment, looked at Xi Zhicai and asked, "What's the problem?" ”

"The offensive in the direction of Shangyong should be strengthened slightly, so that it can better cooperate with the envoy's actions to make peace, and can contain and attract Liu Bei's attention."

"That's a great idea! Haha"

Cao Cao smiled happily.

Cao Cao's envoy entered Hanzhong through Shiquan with great fanfare, and soon, the news that Zhang Liang and Cao Cao wanted to form a military alliance came out from Nanzheng, Liu Bei and Sima Fang also hurriedly sent envoys, Zhang Liang suddenly became popular, and everyone seemed to have ignored the hat of the thief on Zhang Liang's head, intentionally or unintentionally.

At the same time, Cao's army began to carry out a large-scale purge operation in Xicheng, and the troops of Frustration cooperated with the Inhumans and began to actively operate in the mountainous areas, clearing out the Inhuman troops of Liu Bei's camp who infiltrated from Shangyong, and of course, there were also many Inhuman troops infiltrating Shiquan and the west of Shiquan, and clashing with the Inhumans of the Yellow Turban camp.

Splitting the battle between the strangers, the situation in Xicheng seems to be stabilizing, and Cao Cao did not think about the plan of increasing troops in Xicheng, but instead increased troops to Shangyong, which has the meaning of attacking Shangyong in one fell swoop, but Shangyong has Zhang Fei stationed in it, and it is not a simple matter to capture it.

To be continued......
