Now on the other side of Wuzhangyuan and Xiegu, Zhao Yun has just taken the grain that Cao Cao is preparing to transport from Xi'an.

These grains are enough for Cao Cao's entire army to eat in March, and they are very much.

As long as this passage is opened, the grain used by the soldiers of Wuzhangyuan can be mobilized from the side of the valley.

Because now Lu Bu doesn't know how much military ration Cao Cao still has and how long he can hold out.

If Cao Cao was determined not to retreat, then they occupied the 30,000 horses and horses in Dingjun Mountain, and grain transportation would be a problem.

Cao Cao will inevitably make a move on their grain routes.

As long as the passage between the valley and the Dingjun Mountain is opened, they will no longer need to transport grain here.

Even if Cao Cao wanted to do something on the grain transportation route, he couldn't do it.

There are 30,000 soldiers left in Dingjun Mountain to guard, and there are 10,000 cavalry of Zhao Yun on the side of the valley.

Next, it depends on how determined Cao Cao is to Hanzhong.

In fact, even if the transportation route of the sloping valley was abandoned, Cao Cao could completely open up other transportation routes again.

However, if other transportation routes are opened now, it will inevitably be time-consuming and labor-intensive.

In addition, it is not possible to secure a new transportation route.

……

In the city of Hanzhong, the military doctor gave Cao Cao medicine all over his body.

Cao Cao sat alone in the camp and pondered.

At this time, the soldiers outside came in and asked, "Prime Minister, what is the password tonight?" ”

A password is a specific code word set up in the barracks to prevent the enemy from infiltrating and to identify one's own person.

Those who can answer the slogan prove that they are their own people.

If you can't answer, you prove to be an enemy.

Cao Cao, who was thinking about it, couldn't help but say casually: "Chicken ribs"

The soldier who got the password stepped back and quickly conveyed the chicken rib password.

After thinking about it for a long time, Cao Cao finally decided to withdraw his troops and fully withdraw from the Shu Han territory in Hanzhong.

There is no way to do this, their grain and grass will be burned by Dahuaguo, or directly snatched away.

The grain transportation route from Chang'an through the Xiegu and Dingjun Mountains was also cut off by the Great Huaguo.

And what's even more serious is that in fact, Dahan has no extra food.

If you want to continue to transport grain, you must squeeze the major families again, so that the major families can continue to take out the food they have hoarded.

But before, Cao Cao had squeezed them hard enough.

If it is squeezed again, the family will not only hurt the muscles and bones, but also hurt the muscles and bones.

And he is not in the DPRK at the moment, and continuing to do so will inevitably cause a backlash from the family.

What's more, even if they can continue to squeeze grain from the hands of the major families, they must re-establish a transportation route.

This route is not easy to find.

Or you can take the road from Jieting to Qishan, but this road is farther and less safe than the road of the Slope Valley.

In the past, the grain in Yinping City was also burned by Dahuaguo.

Even if they can transport grain through the Jieting and Qishan roads, can't Dahua continue to burn their grain?

What's more, the road of Jieting and Qishan, in Cao Cao's opinion, is absolutely undesirable!

Since there is no way to transport food, they must withdraw from the army now that they have no food.

If they don't retreat, delay it for a few more days, I'm afraid they won't be able to retreat if they want to.

However, it was not so easy to withdraw from the army.

If they retreated with great fanfare, how could Dahua let them withdraw so easily?

If Dahua stuck to them and continued to harass and chase them when they retreated, they would inevitably suffer heavy casualties.

Therefore, Cao Cao must now consider how to evacuate the entire army safely and quickly.

……

On the second day, Cao Cao issued an order to the army of Bajun, Bazhou and other places, ordering them to abandon the city and assemble in the direction of Hanzhong.

At the same time, the army of Jiange, Jiangyou and other places was ordered to be ready to evacuate at any time.

Next, Cao Cao gathered all his forces and put on a plan to attack Dingjun Mountain.

Lu Bu, who got the news, didn't dare to slack off, and analyzed it with Guo Jia and Pang Tong.

Although Guo Jia and Pang Tong were more inclined to Cao Cao, he did not want to attack Dingjun Mountain, but to retreat.

But in this case, the two did not dare to pack tickets, and Cao Cao really wanted to withdraw from the army.

What if Cao Cao was hot-headed and really attacked Dingjun Mountain?

On this day, Dahua is also constantly gathering forces, ready to support Dingjun Mountain at any time.

Nothing was said all night.

On this night, on the Dahua side, Lu Bu sent a large number of sentinels to guard against Cao Cao's attack on the camp.

However, the night was calm and nothing happened.

Early in the morning of the second day, Lu Bu, Guo Jia and Pang Tong, the three of them stood on the city wall, observing Cao Cao's garrison camp.

They found that the camp was quiet, not the slightest sound was heard, and they didn't even see a single living person in the camp.

Finding this situation, Lu Bu couldn't help frowning.

What the hell is this guy doing?

At this time, Pang Tong couldn't help but say: "Your Majesty, the minister suspects that Cao Cao's army has withdrawn overnight. ”

Guo Jia followed and said: "The minister also has this suspicion. ”

Lu Bu couldn't help but nodded, and then sent scouts to survey Cao Cao's camp.

In the end, it was found that Cao Cao's army had evacuated overnight.

Next, Lu Bu quickly sent a large number of scouts to Hanzhong, Jiange and other places, and found that there was not a single soldier on Cao Cao's side in these cities.

They've all been evacuated overnight!

Good!

Now that Cao Cao has withdrawn, the entire territory of Shu Han will be included in the territory of Dahua!

This time, the set goal of sending troops to Shu Han has been achieved.

Dahuaguo's ambition to dominate has begun!

However, Lu Bu didn't want Cao Cao's army to retreat so easily, and if he could kill and wound some of their soldiers now, it would be easier for him to fight in the future.

Lü Bu immediately led the army and pursued it in the direction of Cao Cao's army.

Lü Bu mainly led the cavalry to pursue, while Cao Cao's army was mostly infantry.

And when it comes to evacuation, the speed is certainly not comparable to their pursuit.

It didn't take long for Lu Bu to catch up with the team left behind by Cao Cao.

In fact, it was not so much that Lu Bu caught up with the team left behind by Cao Cao.

It is better to say that Cao Cao's broken team is waiting for Lu Bu's pursuers.

The team left by Cao Cao was waiting at Sanguan.

When he saw Lu Bu's pursuers coming, the broken rear team left by Cao Cao piled up a large amount of firewood on a narrow road that must be passed.

When Lu Bu's army caught up, they directly lit firewood.

Raging fires and billowing smoke suddenly rose into the sky, and then, after Cao Cao broke off, the team quickly retreated.
