Three Kingdoms: The ghost plotter taught Liu Bei to seize Jingzhou first

Cao Cao was in a state of rage before, so he naturally couldn't listen.

Now that he has calmed down and thought carefully, what Jia Xu said is indeed reasonable.

Hanzhong cannot be defended!

Cao Zhen holds the 20,000-plus Hanzhong army, which is extremely rich for Wei at this time.

Between saving people and losing land and losing both people and land, the former is the natural choice.

"But, Wenhe, have you ever thought about it."

"If we withdraw from Hanzhong, and Guan Yu attacks Guanlong from the south, how should we respond?"

"At that time, won't we face the situation of being attacked by the Han army?"

Ma Chao questioned.

Cao Cao's figure trembled, and he suddenly realized the seriousness of the situation, and looked at Jia Xu anxiously.

Jia Xu regained his composure, but stroked his white beard and said calmly:

"Your Majesty, don't forget that we share the danger of Qinling Mountains with Hanzhong."

"Your Majesty, when you attacked Zhang Lu and pacified Hanzhong, you had to cross Qinling Mountains to enter Hanzhong."

"Now if Guan Yu wants to attack my Guanlong, he also needs to cross Qinling Mountains."

"So, although our army is small, we only need to block the valley entrances such as Qishan, Chencang, and Xiegu, and with a small number of troops, we can block the Han army in the valleys."

"In this way, my Guanlong is still as solid as a rock, Your Majesty."

Jia Xu said his response strategy.

To put it bluntly, it is to use the danger of Qinling Mountains to resist the advantage of Han army's strength.

Cao Cao's eyes lit up, and he hurriedly ordered to bring the map.

The left and right imperial guards hurriedly took out a map and showed it to Cao Cao.

Cao Cao's eyes fell on the area between Hanzhong and Guanlong.

There was a mountain range between them, called Qinling.

There were only three valleys between Guanzhong and Qinling: Chencang Road, Xiegu Road, Luogu Road, and Ziwugu Road.

Which of these three valleys was not rugged and difficult to travel?

Even the easiest Chencang Road required a road to be opened when encountering mountains and a bridge to be built when encountering water. It was extremely steep.

The difficulty of this was naturally experienced by Cao Cao himself when he attacked Zhang Lu.

As for the Longxi line.

If the Han army wanted to capture Longxi, they had to go out of the Qishan Pass.

He only needed to set up a camp at the Qishan Pass to stop the Han army from going out of Qishan.

As for the several valley entrances such as Chencang Road, it is only necessary to set up camps at the valley entrances to block the Han army with a small number of troops, making it impossible for them to deploy.

The defenders of the Wei army, with Guanlong at their backs, have sufficient food and grass to supply. (To read the novels of Baoshuang, go to Feilu Novel Network!)

The Han army blocked in the valley has to endure the difficulties of transporting food and grass.

If you calculate it this way, at most 20,000 people should be enough to block the Han army.

"｀Well, Wenhe's words make sense."

"The danger of Qinling Mountains is shared by me and the big-eared thief. He wants to get out.Qinling Mountains, it's not easy. "

"In this case, losing Hanzhong may not necessarily mean irreparable consequences."

Cao Cao muttered to himself, the nervousness on his face gradually calmed down, and he began to regain his composure.

Ma Chao also had no way to say (King Qian's) thing.

After pondering for a long time, Cao Cao took a deep breath, and his eyes were determined.

"Just follow what Wenhe said, and quickly send an edict to Cao Zidan, ordering him to bring the 20,000 Hanzhong troops back to Guanzhong safely for me."

"Also, order him to deploy defenses at the entrances of the valleys immediately after leaving Sichuan, and never retreat a step, let alone let a Han soldier into Guanzhong."

"Otherwise, I must take his head!"

In desperation, Cao Cao finally made the decision to abandon Hanzhong..
