Although Sima Yi said the way to keep Nanyang, Cheng Yu still felt that it was inappropriate, and bowed his hand to Cao Cao and said: "Duke Wei, the stakes are so high, please think twice!" ”

Cao Cao was also thinking about Sima Yi's strategy.

Sima Yi's strategy is indeed good, once it succeeds, Guan Yu will be destroyed, and even Jingzhou, he may also get it.

But if you are not careful, Nanyang may also be lost.

Nanyang is a military location, which can threaten Luoyang to the north, and attack Xudu to the northeast.

Luoyang is the Central Plains, Xuchang is Cao Cao's old nest for more than 20 years, and it is now the capital of the Han Dynasty, Cao Cao is now unable to command the situation in Nanyang, but he does not dare to take risks with Nanyang.

Seeing Cao Cao's hesitation, Sima Yi continued: "Ordering General Cao Ren to send troops to Shangyong can restrain Liu Bei's troops, relieve the current pressure of Duke Wei, and send a letter to Sun Quan, which can make the situation in Jingzhou erosive.

In this way, Duke Wei won Hanzhong, Guan Yu lost Jingzhou, and the Sun-Liu alliance broke down, so that his two families killed each other, among the three, Duke Wei regained an absolute advantage, killing three birds with one stone, and asked Duke Wei not to hesitate! ”

At this moment, Cao Cao wanted to agree to Sima Yi's plan, but Cao Cao didn't dare.

Nanyang is too important, he is afraid that if the strategy is used, Cao Ren and Xiahoudun will not be able to protect Nanyang.

What's more, he is now trapped in Hanzhong, if Guan Yu or Sun Quan is allowed to fight Xuchang, then he will be the second Yuan Shao.

Cao Cao waved his hand and asked, "Zhongda, didn't you say that you have four strategies, what are the other two?" ”

Sima Yi shook his head, Cao Cao asked this, he definitely didn't plan to use his Jingzhou two strategies.

Sima Yi arched his hand and said: "In addition to the two strategies of Jingzhou, Yi also has two strategies for the benefit of the state, and now the soldiers and horses of the Duke of Wei have suffered a lot of losses, so you can contact Xianbei and Xianbei to step down to the root, and let him lead the Xianbei cavalry south to help!"

In addition, last year, Duke Wei contacted the barbarian kings of Nanzhong in Yizhou, as well as the surnames of Haoqiang, Zhu Bao, Yonghong, and Gao Ding

Wait, now that the Duke of Wei is dragging Liu Bei here, he can send people to promise heavy profits and let them quickly send troops to attack Shuzhou City, so that Liu Bei's backyard will catch fire and withdraw from Hanzhong. ”

"Hmm!" Cao Cao listened to this plan and immediately agreed: "Bu Dugen has always been good friends with me, if I have a request, he will come, Wen He, write a letter for me, and let Bu Dugen send 50,000 troops to help."

Cheng Yu, quickly sent a messenger to contact the barbarian king Zhu Rong, Zhu Bao, Yonghong, and agreed: After the matter is completed, Nanban will get Nanzhong, Zhu Bao will get Shuchuan, and Yonghong will get Bachuan! ”

"No!" Cheng Yu, Jia Xu gave up his hand.

This time, Cheng Yu did not object.

But Jia Xu secretly shook his head and sighed in his heart.

Sima Yi's four strategies, in fact, if you look closely, there are only two strategies, one for Jingzhou and one for Yizhou.

It is the best policy to target Jingzhou, once successful, Liu Bei will definitely return to the army to save Jingzhou, and Cao Cao can win Hanzhong without a fight.

Moreover, the Sun and Liu families will also break up, and the disaster will lead to the east, and the one who will benefit the most is Cao Cao.

At that time, Cao, Sun, Liu, and the three families, Cao Cao will still be a dominant family, and there will be surplus with one enemy and two.

And the strategy for Yizhou can only be regarded as a next policy.

What if Bu Dugen led the Xianbei soldiers and horses, it would only be comparable to Liu Bei's soldiers and horses at that time.

Moreover, the terrain of Keigu is narrow, and it cannot be used, so it can only play a role in boosting morale and have the strength to fight Liu Bei head-on.

If Liu Bei can't hold on, after a long time, he will just waste grain and grass in vain

。

As for letting the barbarian king of Nanzhong, Dahu attack Shuzhou City, its threat is far less than Sun Quan's raid on Jingzhou, Liu Bei only needs to divide 20,000 or 30,000 troops to go back, and the danger of Chengdu will be solved.

At that time, the war in Hanzhong still had to be stalemate, and Liu Bei could not be defeated.

However, Jia Xu didn't dare to say what he thought in his heart, if Cao Cao used the best strategy to cause Nanyang to lose, his sin would be great.

And put yourself in his shoes, if it were him, he wouldn't dare to use the best strategy, it would be too risky!

As soon as this order was given, Cao Cao's thoughts were clear, and he only felt that his head was much better, and he was magically refreshed, and he muttered: "Xiahou Yuan is there, but let him continue to hold on." When Bu Dugen arrived, Liu Beiruo asked Zhang Fei to divide his troops to support. Xiahou Yuan can be ordered to bypass Yangping Pass, camp in the area of Zoumaling and Dingjun Mountain, and cut off the supply from Hanzhong to Yangping Pass! ”

"No!" 1. The general who was responsible for contacting Xiahou Yuan surrendered his orders.

But he said that Liu Bei went all the way north to Kei Valley.

Twenty miles south of the Kei Valley, the camp was built by Zhuge Liang himself, surrounded by mountains and rivers, and was impeccable.

Cao Cao heard that Liu Bei's army was coming, and led the elite cavalry out of the camp to inspect the situation of Liu Bei's camp.

Cao Cao and the generals were on a mountain ridge, and when they saw Liu Bei's military camp from afar, they couldn't help but be surprised: "This Liu Bei's ability to use soldiers is only average, how can he have arranged such a camp, I have used soldiers for more than 20 years, and the camp can only be built like this, who built this camp?" ”

All the generals shook their heads when they heard this, and Xu Huang arched his hand and said: "Scouts can find that Liu Beijun is the general, only Zhao Yun, Lin Xiao, Wei Yan, Zhang Ren and others. Zhao Yun, Wei Yan and others, only the courage of the horseman, but Zhang Ren, the last time I was defeated, but he raised fire as a soldier, causing me to fail, this camp is not Zhang Ren? ”

Sima Yi shook his head and said: "This camp is secretly in line with Qimen Dunjia, and in many places, I can't understand the subtleties. Although Zhang Ren is a good general, he is afraid that he will not reach this level, otherwise Liu Beiyan can defeat him? If what I expected is good, it should be Zhuge Kongming! ”

Cao Cao's face sank when he heard this: "Zhuge Villageman still knows the formation of soldiers and horses?" ”

Sima Yi nodded: "When I was in Xiangyang, I saw his military formation, and the world can only compare to the number of five fingers......"

Cao Cao was silent for a moment.

Zhuge Liang's wisdom is already invincible in the world, and now his attainments in the art of war are still so superb, which makes it even more difficult to deal with.

"I also want Liu Bei to come from afar, and send troops to attack the camp tonight to frustrate Liu Bei's spirit, now that I have seen this camp, let's think about it in the long run."

Cao Cao shook his head, and was supported by Han Hao and went down the hill.

In the Shu barracks, Liu Bei also stayed with the generals.

Liu Bei said: "According to the report from the scout, Cao Cao has expanded his camp these days, built fortifications everywhere, and the scale of his camp is still more than that of our army, and he now only has 70,000 people left...... But what do you think about the establishment of such a large camp? ”

Zhuge Liang smiled: "Ruoliang's expectation is good, Cao Cao is only afraid that he will save the soldiers!" ”

"Rescuers?" Liu Bei frowned slightly: "Now Cao Cao has about 500,000 soldiers and horses, except for Jingzhou, Yangzhou, Xuzhou and other war zones, as well as Luoyang, Xuchang, Yecheng and other large places, the rest of the northern places, can mobilize no more than 350,000 soldiers and horses, and they are distributed in various places, it will take half a year to gather them, it should be impossible to ......"

Zhuge Liang explained: "The central Xianbei Shan Budugen has always been close to Cao Cao, and a large number of clansmen live in Yanmen, Taiyuan and other places. ”

"Budugen?" Liu Bei's face sank when he heard this.

Zhuge Liang said with a smile: "The lord doesn't have to worry, even if the Budugen Xianbei cavalry comes, the lord only needs to hold on, until June, the rainstorm continues, the climate of Kei Valley is changeable, the cold and warm changes of day and night are huge, and it is also a group of sick soldiers who come to consume grain and grass in vain."

Liang is not worried about this, but about the situation in Jingzhou and Chengdu. ”
