Although it was August, the weather was still as hot as ever, and the autumn tiger was still exerting its might on the land of Shuzhong, torturing the people of Yizhou with the last scorching heat.

When it comes to summer retreat, there is a good place to go in the west of Chengdu, the top of Xiling is covered with white snow all year round, even if it is the middle of summer, standing on the top of the mountain, you can also feel the chill hitting people, the canyon at the foot of Xiling has undoubtedly become the best summer resort, green bamboo is everywhere, the mountain spring is murmuring, a cool scenery.

Liu Yin took many family members from the Anping Mansion to appear in the Bison Valley at the foot of Xiling.

But Liu Yin didn't come to escape the summer, let alone come for a leisure vacation.

After returning to Chengdu from Hanzhong, Liu Yin took a leave of absence from Zhijin Wu He Zeng, and went into the Ma family manor in the western suburbs of Chengdu, and never came out for more than ten days.

The theft of the Hanzhong defense map, the main responsibility lies in the Hanzhong Governor's Mansion, because the Hanzhong Governor's Office is not well kept, so that the Wei State spies have an opportunity, although Liu Yin's Lieutenant's Mansion is fully investigated, but still can not prevent the outflow of the Hanzhong Deployment Map, but the Lieutenant's Mansion can only bear the secondary responsibility. In this incident, Hu Ji, the governor of Hanzhong, only received some verbal punishments, and was not punished for this, correspondingly, Liu Yin's fault is even more insignificant.

However, after returning to Chengdu, Liu Yin's mood has been very low, and even Zhijin Wu He Zeng had to comfort: "Actually, our lieutenant's mansion has done its best, Liu Youcheng doesn't have to mind too much, this trip to Hanzhong can be regarded as a remarkable achievement." ”

He Zeng refers to the outstanding achievements naturally refers to the interception of a senior spy of Wei in Chen Cangdao, but Liu Yin just shook his head and smiled bitterly, even if the performance is excellent, what is the point, now the Hanzhong defense map has reached the hands of Zhong Hui, the Wei army will soon be in the city, and the fate of Shu has reached the moment of life and death, and Jiang Wei stubbornly refused to change the defense system of Hanzhong, and it is foreseeable that the loss of Hanzhong is already imminent.

"Lord He, the lower officials are a little tired, and they want to take a few days off first, I don't know if it's okay?" Back in Chengdu, there is no major errand in the Lieutenant's Mansion at present, so Liu Yin thought about taking a leave of absence to rest for a few days.

He Zeng agreed to Liu Yin's request almost without hesitation. "Liu Youcheng has been working hard all the way, he should rest for a few more days, anyway, there is no major event in the Lieutenant's Mansion these days, Liu Yin just needs to rest at home for a few more days."

Liu Yin's leave is not to rest, he is about to burn his buttocks, and he still has leisure and leisure to recuperate at home. On the way back to Shuzhong, Liu Yin had already secretly calculated, the Wei army attacked Shu in five ways, and the loss of Hanzhong was almost a certainty, and it was no longer meaningful for him to stay in Hanzhong at this moment, the lieutenant's mansion did not directly mobilize the power of the army, and it was impossible for the people and horses in Hanzhong to be under their own control.

Taking a step back, even if he can command more than 20,000 horses in Hanzhong, he will face an army that is eight times that of Zhonghui, and Liu Yin, who has never had combat experience in ancient battlefields, even if he is fully open, he does not have the power to turn decay into magic, and if he wants to win Zhonghui Deng Ai, a first-class famous general in the last years of the Three Kingdoms, Liu Yin thinks it is a fantasy when he thinks about it.

In the battle of Hanzhong, in the face of Jiang Wei's strategy of gathering troops in the valley, he did not attack the cities one by one as Jiang Wei wished, but adopted the strategy of encircling but not fighting the two cities of Hanle, and concentrated superior forces to attack Yang'an Pass, which is quite a bit of the strategic meaning of the US military in the Pacific islands during World War II. The fall of Yang'an Pass opened a door for the Wei army to enter Shu, and Jiang Wei was forced to retreat to the Sword Pavilion.

The loss of Hanzhong is equivalent to the loss of an important defensive barrier, and this will be the case of Deng Ai smuggling into Yinping Road and the complete collapse of Shu.

Deng Ai's success has certain accidental factors, and there are also certain inevitable factors. During the decades of Zhuge Liang's reign, Hanzhong has always been firmly in the hands of Shu, and the Wei people have never had the opportunity to enter the Hanzhong Plain, so naturally they can't talk about the danger and surprise attack on Yinping Dao.

But Liu Yin is not Zhuge Liang, he can't keep Hanzhong, but he is from 1,700 years later, he is clear about the process of Wei's destruction of Shu, he can't keep Hanzhong, can't he still keep the Yinping Trail?

When did Deng Ai take the Yin Ping Path? It is clearly recorded in the history books: in winter and October, Ai traveled more than 700 miles from Yinping Road to no man's land, dug mountain passages, and built bridges and pavilions. The mountains are high and the valleys are deep, which is extremely difficult and dangerous, and the grain transportation will be scarce, and it is frequently in danger. Ai wrapped himself in a war and pushed down. The soldiers all climbed the wooden edge cliff and the fish went through. Ascend to the river first, and Shu will look at the wind and descend.

In other words, there is only about two months left for himself, who is Deng Ai, that is a famous general who has experienced a hundred battles, and wants to fight to the death with Deng Ai in Yin Ping Dao, in addition to courage, Liu Yin really doesn't know what kind of advantage he has.

Writing to the imperial court, Chen said that the possibility and danger of the Wei army's sneak attack on Yinping Dao must be something Liu Yin has to do. But at the same time, he knew very well in his heart that since he forced Jiang Wei away, Huang Hao's power in the court was simply in full swing, and whether this letter could go to Liu Chan's hands was another matter, even if Liu Chan saw it, could it attract attention?

Liu Yin didn't dare to pin his hope of saving Shu from danger on Liu Chan, but as long as Liu Chan had a little blood, he would not surrender when Shu still had a big country in his hands.

Judging from the course of history, Shu was indeed killed by Deng Ai's sneak attack, in order to avoid the mistakes of the past, the only hope is to fight this Yinping resistance battle, which is no less significant than the Tashan resistance battle in the Liaoshen campaign in later generations.

It has been a few days since he crossed into this world, Liu Yin also clearly saw the current environment he was in, the strong enemy was like a hungry tiger, and the power of Shu disappeared in the endless internal friction, although he held the position of lieutenant Youcheng, and held the transfer authority of the Hubu battalion, but it does not mean that he can really transfer these forces to the direction of Yinping, if without Liu Chan's consent, as soon as he leads his troops out of Chengdu, the impeachment is estimated to be able to fly into the palace like snowflakes.

What's more, Deng Ai is bringing 30,000 brave soldiers who have been through a hundred battles, how can the pampered Imperial Forest Army be an opponent?

If you want to deal with Deng Ai, you have to find another way!
