Spoiling History: Starting from the Three Kingdoms

After Cao Cao's army set off, Guan Yu was the one who felt the pressure most directly.

Within one day, emergency military information was sent to three places from north to south, Duyangwuyinbiyang and Duyangwuyinbiyang, which border Jingzhou and Yuzhou, and the contents were basically the same:

The army crossed the border and the isolated city was trapped.

In the Bowang County mansion, Xu Shuzhan looked at the sand table map carefully.

While clearly marking the movements of Cao's army on the sand table according to the military information, he smiled at Guan Yu who was fully armored and said:

The thief Cao is here to fight to the death.

In the past year or so, I had defeated Cao Cao in battle and almost captured him alive, which was certainly a joy.

But as for the surprise, Kong Ming sent several arithmetic classics jointly annotated by him and Liu Ba, as well as a long letter on the application of arithmetic.

As a guarantee for future generations, Kong Ming recommended it, so Xu Shu naturally had no reason not to believe in this arithmetic.

After half a year of intensive study, Xu Shu found that it became easier for him to coordinate Jingzhou's military affairs. By relying on arithmetic, he could roughly calculate the income and expenditure of land tax without leaving home.

Since it can be used to save oneself, it can also be used to measure the enemy.

When Guan Yu was staying in Bowang County to assist Duyang, Wuyin, and Biyang cities, Xu Shu interviewed Cao Cao through the mouths of the surrendered soldiers of Cao's army obtained from the Battle of Jingxiang and the people who fled south due to the war. The ambiguous situation of farming under the rule.

Supplemented by the data records of land and acres in various states and counties in the world that the protagonist obtained in Chang'an after entering Guanzhong.

After receiving the dictation from Shi Guangyuan, who was still working as an agricultural officer before returning to the south, Xu Shu finally vaguely pieced together the number of fields, people, and wealth under Cao Cao's rule, and based on this, he also calculated the approximate amount of food and grass that Cao Cao could allocate. number.

This number is of course not accurate, but at least the range of deviation is not very large, which is enough to make Guan Yu confident about this battle.

This food and grass is enough for how many armies and how long it will last. Xu Shu has clearly listed it.

Therefore, Guan Yu couldn't help laughing in agreement and said:

Now we know what it means to count the number of people in the temple. Yuan Zhi is strategizing, and this battle has become a state of knowing ourselves and the enemy. How can we win without too much?

Xu Shu also laughed:

Why is Yunchang so humble? Some numbers are useless without Yunchang's courage in battle.

The loud laughter of the coach and military advisor spread far and wide in Bowang County House, and everyone who heard it admired:

The army can still handle it calmly, he is worthy of being General Guan!

But it’s a laugh, and we still need to come up with ways to deal with it.

Guan Yu stepped forward slowly and stared at the sand table carefully.

The most eye-catching thing in the whole of Jingbei is the Jingshui River. It originates from Funiu Mountain all the way south and finally joins the Han River in Xiangfan. It also divides Jingbei into east and west parts.

There is also Tuanshui Danshui Fertile Land to the west of Huishui River, which can be called the fertile land of Jingbei. Wancheng, Anzhong, Juoyang, Rangxian, Champion, etc. are all scattered here.

The lack of river branches in the east of Feishui River is not conducive to farming, so there are only two counties in Bowang and Jiyang located on the east side of Feishui River. But the advantage is that this open and waterless plain has become a place where cavalry can gallop freely.

Guan Yu could already foresee that the cavalry from both sides would definitely fight to determine the final outcome of the battle.

Cao's army passing through Duyang will definitely come to gain hope.

Guan Yu clicked on the sand table with his arms in his arms, because Bowang and Duyang were only a hundred miles apart, and if they had Bowang, they could take Xi'e and attack Wancheng, which was a close relationship.

Xu Shu also nodded on the sand table and said:

The two places of Wuyin and Biyang are only more than eighty miles apart. Cao's troops from the two places will most likely join together, so that they can attack Jiyang and attack Wancheng.

But in my opinion, it is more likely to abandon Jiyang and attack Xiangfan southward, so as to cut off Jingzhou in the middle and cut off our army's retreat.

After just saying that, Xu Shu pointed his finger down at Jiangxia with a relaxed expression:

It's just that if Cao Jun does this, I'm afraid he will crush Zilong into clay.

Guan Yu nodded in approval, and at this moment, Hou Yin came in to report:

The three armies are ready, just waiting for the general's order!

After hearing this, Guan Yu carefully put on his douche, and then picked up the brightly polished Yanyue Sword beside him. After nodding towards Xu Shu next to him, the dragon and tiger stepped into the wind.

Pass my military order, go out and defeat the thieves!

Xu Shu followed him briskly, and they got on their horses after leaving the county house. What they saw when they left the city was a troop of soldiers and horses that had been prepared and ready to go.

The bravery of the strong soldiers soared to the sky, and the ferocious aura of the fine cavalry rushed towards his face. Even though it was not the first time he saw this scene, Xu Shu was still fascinated by it and couldn't help but whisper:

With such a good soldier, Yun Chang will definitely win!

Hearing this, Guan Yu spurred his bloody warhorse forward, pointed the cold Yanyue Sword at the sky, and the sound shook the surrounding areas:

The great man is victorious!

Long branches towered like trees, and tens of millions of people shouted loudly:

Wan Sheng!

And long before Huang Zhong saw Cao's army marching out, Zhao Yun, who was stationed in Jiangxia, had quietly left here and led his troops north.

This was already in Zhao Yun's plan, because there were many reasons to leave Jiangxia.

For example, Gan Gui relied on the power of the Jingzhou Navy to determine that no one would dare to rebel against the Yangtze River, and no one in Jiangxia would dare to rebel against his master.

For example, Samoko managed his tribe in an orderly manner, and after settling down in Jingnan, he even had enough energy to support Shanyue in Jiangdong.

Of course, according to Samoko, it was mainly to repay Ma Liang, who was now making suggestions for Shan Yue.

What Zhao Yun didn't expect was that Gan Ning also regained command of the 800 old troops and insisted on staying with him to go north together.

The reason given was also plausible, saying that the current grievances between Sun and Liu were all due to Cao Cao. He Gan Ning was not working for Xuande Gong, but just had a debt to settle with Cao Jun.

Seeing that the riding skills of Gan Ning and his 800 old men were quite good, Zhao Yun simply acquiesced.

Everyone in the group can ride a horse and can travel hundreds of miles a day. It is safe to pass through Suixian County and Anchang. Zhao Yun has already planned to go straight to Bowang to listen to General Guan's orders.

As a result, when he arrived in Huyang at dusk, he saw that everyone in the county was rushing to flee south, and Zhao Yun felt a thump in his heart.

To the east of Huyang is Pingshi County, and to the east of Pingshi is Biyang.

The soldiers who went to inquire about the news soon brought back complete news.

Cao's army came from the direction of Biyang and directly occupied Pingshi County and invaded the people's fields and property. They will probably attack in the direction of Xiangyang tomorrow.

How many people? This was the news that Gan Ning was concerned about.

Nearly 30,000 people. This is a rough estimate based on what the soldiers saw based on asking many common people.

Hearing this, Gan Ning had a bloodthirsty smile on his face and said:

General Zhao, are you interested in doing something big?

Under the light of the torch, Zhao Yun saw a wild and uninhibited smile on Gan Ning's gangster face for the first time.

Come on.

For some reason, Zhao Yun felt that his heart was beating two minutes faster.

Gan Ning stood up and pointed to the east and said:

Taking advantage of the enemy's unpreparedness, he set fire to the camp and robbed it. Thousands of horsemen marched on the camp. Do you dare to go with us?

Why not? He was Zhao Zilong who was praised by later generations for being full of courage!
