Shu Chen

Chapter 390
Xia Houru's letter was transferred to Sima Yi three days later.

Because he is not in Chaona County, Anding County, but the warlord has already rushed to Chencang City, Youfufeng.

After spending more than one year of planning, half a year's planning and exhaustive thinking, he finally ushered in the day when the strategy was achieved-Zhuge Liang, Prime Minister of Shu, sent troops!
Regardless of the lack of national strength and the shortage of food and fodder, Ni Shu finally took the first step of militarism.

Regarding this, Sima Yi was both gratified and awe-inspiring.

As the saying goes, "A person who travels a hundred miles travels halfway through ninety years", he is as scheming as he is, and he will not make things negligent or flawed when the dawn has already appeared.

In particular, even if Ni Shu sent troops, the route and strategy would be different from what he imagined.

For some unknown reason, Zhuge Liang, Prime Minister of Shu, went out of Dasan Pass through Chen Cang Road, not Xiao Pass!

If you come from Xiaoguan against Shu, you can rely on the condescending geographical advantage. Whether you go south to attack the cities of Youfufeng or go north to the Wushui River Valley to cut off the grain road of the Wei army in Hexi, you can judge the situation and act freely.

Moreover, since Nishu occupied Longyou, the hoarding of soldiers and food and fodder has been in Jixian County, Tianshui. Sending troops from Xiaoguan can also save the cumbersome transfer of food and fodder.

But if you go out of Dasan Pass through Chen Cang Road, you will have more disadvantages!

One, Chencang City is a strong city!

In the past, when Liangzhou was out of control, the rebel army surrounded Chencang for nearly three months and did not pull it out.

At that time, it also led to internal strife in which the kingdom of the rebel leader who called himself "General Hezhong" was abolished by Han Sui and Ma Teng.

The other is the difficulty of transporting grain and fodder.

Walking the rugged and narrow Chencang Road, it is impossible to borrow animal power, and the food, fodder and supplies can only be transported by manpower, which will greatly increase the burden on the soldiers.

Moreover, Wudu County is a land of rolling mountains and is not rich in grain and fodder.

When the Shu army dispatched troops from here, it still needed to transfer food and fodder from Hanzhong or Longyou, which added countless losses.

Not to mention far away, when Cao Cao of the Wei Dynasty conquered Zhanglu in Hanzhong, he took the Chencang Road, and once thought of stopping the army because of the difficulty in transporting grain and fodder.

In the end, it was the limitations of the battlefield.

Chencang City is located in the Weizhihui (Baoji), on the north bank of the Weishui River.

If Ni Shu wanted to besiege or attack the city, he had to build a pontoon bridge to cross the Wei River.

In the actual situation where there are many troops in Wei and few in Shu, a fatal flaw will be exposed-if Ni Shu does not fully cross the Wei River to fight with all his strength, there will be no danger in Chencang; but if they all cross the river, they will face another The danger of being cut off from the way back.

Relying on the superiority of his troops, Sima Yi did not send a few elite troops from Mei County up the Weishui River to occupy San Pass!

At that time, the Shu army will face a dilemma and the loss of grain roads.

Become a turtle in an urn!

In fact, at the beginning of the preparations for the war, all the generals of Yongliang and Liang of the Wei State asserted that if Zhuge Liang, Prime Minister of Shu, couldn't restrain himself from sending troops, he would definitely go through Xiaoguan'er!
But things are so strange.

Zhuge Liang, Prime Minister of Shu, dared to come out from Dasan Pass in Wudu with only [-] soldiers in command!

This is why Sima Yi's heart is awe-inspiring.

He did not think that Zhuge Liang, Prime Minister of Shu, could not even foresee such an obvious crisis.

Where there is an abnormality, there must be a demon.

Therefore, it can be asserted that he must rely on something!
However, where did the Shu army rely on evil?
After Sima Yi supervised the troops to defend Chencang, he was still puzzled by this.

In particular, the Shu army is still camping at Linshui (Qingjiang River) at the mouth of the Chencang Road Valley, and has not approached the Weishui River, let alone intending to encircle Chencang City.

Just at this time, Xia Houru's letter arrived.

After hearing that Wei Yan's troops, who were fiercely using troops, missed the opportunity of "soldiers halfway to attack", and also held back their troops and let Guo Huai's troops rush to Laowei County, Sima Yi immediately felt a chill down his spine.

Or to put it another way, no matter how smart Zhichi was, he could vaguely sense that danger was approaching.

What does Zhuge Liang, Prime Minister of Shu, want to do?

In the Governor's Mansion of Wei Yongliang, the frowning Sima Yi stood alone in front of the cowhide map, thinking carefully about his most likely negligence.

The map is huge.

It not only covers Yongliang and Liangzhou, Longyou and Wudu, and Hanzhong County, but also distinguishes the Han and Wei dynasties with small silver needles adorned with red and yellow tassels, so that the deployment of troops by both sides is clear at a glance.

After a long silence.

After Sima Yi's gaze traveled back and forth between Hexi and You Fufeng many times, he finally landed on Hanzhong County.

He didn't feel that there was anything wrong with the deployment of troops in Naowei County, Yuyin City Fortress, or Guanzhong Chencang, but now there is still Hanzhong County in Nishu and there is no movement!
It is also the place where accidents are most likely to happen.

And he knew that there were [-] soldiers guarding Shuhan Zhongjun all the year round.There are many Qinling valley roads connecting Hanzhong and Guanzhong, such as Baoxie Valley, Tangluo Road, Ziwu Valley and Yugu Road.

Could it be that the Shu army is about to take the Qinling valley road to attack Guanzhong?
Sima Yi asked himself, and couldn't help but cast his gaze on the three eastern counties.

Gein, if the Shu army had this thought, the most likely thing would be to go to Ziwu Valley.

Needless to say, the exits of Baoxie Valley and Tangluo Road are both within Youfufeng. Before Wei State lost Longyou and before Cao Zhen died, many sieges were built to guard them.

If the Shu army took these two valley roads, it would be almost impossible to hide from the Wei army's scouts.

Moreover, he supervised a [-]-strong army and stationed in Youfufeng. Even if the Shu army managed to hide the situation from the scouts, they could not achieve the "surprising" effect of affecting the battle situation.

And there is no need to worry about the valley road whose entrance is in Weiguo County.

But if the Shu army goes to Ziwu Valley, wouldn't the Wei army guarding the three eastern counties be able to cut off their retreat?
Thinking of this, Sima Yi, who once supervised the military affairs of the two states of Jing and Henan and drove the troops to capture Meng Da, suddenly became brighter.

He suddenly remembered something!

More than a month ago, in the military newspaper transferred from Luoyang, it was recorded that Wang Chang, the governor of Jingzhou, made a plea: the Shuguan Xingbu stationed in Hanzhong County attacked Xunkou to encircle the siege.

In the first battle, it was pulled out and all the fortifications were destroyed.

However, the imperial court decided that Xunkou was too far away from Shangyong's garrison troops (the Xicheng Lishu had been taken back to Hanzhong by the Han army before, and the city had been abandoned long ago), and that it would be difficult to rescue it when it was attacked again, so it no longer repaired it.

That is to say, if the Shu army goes to Ziwu Valley, the Wei army guarding the three eastern counties may not feel it!
Even if you are alert, you cannot send troops to contain it in time!
"Come on!"

He yelled loudly to the guards on duty outside the office. Sima Yi, who was thoughtful and thoughtful, was already sitting in front of the desk and writing vigorously. He planned to write a letter to warn Wang Chang, the governor of Jingzhou, so that he could prepare early.

However, he was one step too late after all.

Before the soldiers on duty outside the house could respond to the sound, a civil official from the Dudu Mansion came in a hurry and reported loudly, "To the Dudu, Jingzhao County is here to report urgently!"

These words also made Sima Yi's body stiff.

The pen in his hand also fell quietly, dyeing the unfinished silk with a large ink stain.

However, it is useless.

There are urgent reports from Jingzhao County in the rear, which also means that the soldiers of Shu have already left Ziwu Valley
