Liu Bei sent Sun Gan to Xiangyang to denounce Liu Biao's act of "making peace with Cao Cao alone", which made an additional claim for the future disappearance with the pro-Cao faction in Jingzhou.

In line with the consideration of waste utilization and selling favors at both ends, Liu Bei will of course send someone to hurry up and chase Zhuge Jun, who has been gone for ten days, and synchronize the latest information from Liu Biao to him.

In this way, it is convenient for Zhuge Jun to send Yuan Tan an extra bargaining chip.

Within Yuan Shao's camp, there must be resentment about "the other princes in the world who are rebellious with their edicts, when we are fighting to the death with Cao Cao, they actually just talk about not practicing, do not save when they die, and do not send reinforcements to backstab Cao Cao".

Although Liu Bei doesn't care about offending Yuan Shao now, who would be too much to be able to fish for a more friendly external environment.

At that time, as long as Liu Bei sends someone to warn, he will be able to form a sharp contrast with Liu Biao. Let Yuan Shao and his sons realize:

"Liu Biao and Cao Cao made peace alone, and after the peace, they made a lot of money in a muffled voice, and they didn't say anything to remind us as friendly troops, and I wish that the main force of Cao's army would free up their hands to fight with us, so that we could lose both Liu Biao and pick up the cheap.

It was Liu Bei, he didn't mean not to beat Cao Cao, but he was tripped by Sun Ce's backstabbing. After discovering that Liu Biao and Cao Cao had made peace alone, he finally sent people to warn us and let us be careful that Cao Cao was freeing his hands."

In this comparison, Yuan Shao will hate his allies in the future if he will not save them, and most likely he will hate Liu Biao even more, so as to reduce the hatred value of Liu Bei.

Once Yuan Shao has three longs and two shorts, the consistent friendly relationship between Liu Bei and Yuan Shao's camp is more conducive to Liu Bei winning over one of Yuan Shao's sons, and it is always right to get a good relationship in advance.

It's a pity that no matter how quickly Liu Bei hurried to warn, he would definitely not be able to catch up.

When Liu Bei learned the news of Liu Biao and Cao Cao's peace, more than half a month had passed since Liu Biao and Cao Cao really made peace.

After all, Liu Biao also knows that it is a shame to make peace alone, and he will not take the initiative to publicize it. Liu Bei confirmed it only after observing the phenomenon of Cao Jun and Liu Biaojun withdrawing their troops in the Northeast Theater of Nanyang County, and then conducting in-depth investigations, which took time.

After Liu Bei learned about it, it would take him a few days to make a decision, and he would send someone to catch up with Zhuge Jun, and then go around in a big circle to Qingzhou.

The time it takes to do all this is definitely much slower than that of Cao Jun, who is on the inside.

When Liu Bei arrived, the second battle between Cao and Yuan was estimated to be over, and the daylilies were cold.

Liu Bei just went to pick up a warning favor for nothing, as for whether the warning is effective or not, it is none of Liu Bei's business.

……

There are two flowers, one on each branch.

March 20, Yingchuan County, Xudu.

The timeline goes back to three days after Cao Cao had just reconciled with Liu Cousin.

After curbing Liu Biao's attempt to continue north from Bowang into Yexian County, taking all the dangerous passes of Tongbai Mountain and threatening Xudu, Cao Cao, who had been anxious in recent months, finally breathed a sigh of relief.

Although he won the battle of Guandu three months ago, it was extremely thrilling and lucky.

Among the three people Xu You, Zhang He, and Gao Lan, if any one of them surrendered, Cao Cao thought that he would not be able to win Guandu.

It was finally won, but it was actually a miserable victory. In the direction of Nanyang behind it, the important town of Wancheng was stolen by Liu Biao at the end of the Guandu stalemate.

This butterfly effect, which did not exist in history, also forced Cao Cao to withdraw and curb Liu Biao. Make sure that Liu Biao is beaten and beaten to the point that he has no ambition for the time being, so that he can expand the results of the battle against Yuan Shao again.

But at this juncture, Xun You, who originally advised Cao Cao to ignore Liu Biao and only pursue Yuan Shao, jumped out and offered a completely different, but very reasonable strategy:

"Ming Gong, now our army is clearly forcing Liu Biao to the south with a large army, once Yuan Shao knows, Yuan Shao will inevitably despise our army, and feel that he has seized a golden opportunity to take advantage of the fact that the main force of our army is contained by Liu Biao, and take advantage of the weakness on other fronts to occupy our state and county.

Since our army can quickly make peace with Liu Biao, it will inevitably be able to return to the army quickly, and take advantage of Yuan Shao's lone army to attack head-on and further weaken Yuan Shao's troops. Then counterattack Hebei, it will be able to break through.

Although Yuan Shao was defeated before, Jiang Qi's troops retreated, and the generals of Youzhou, such as Jiao Touch, and Zhang Nannan also successfully withdrew, and only Zhang He's Gaolan troops all surrendered to our army. If our army immediately counterattacks Hebei and launches an offensive attack, its strength may not be able to quickly defeat the enemy.

However, if Yuan Shao attacked the enemy again, he would be weakened by our army in the active attack. Then our army will take advantage of the situation to counterattack, and we will definitely be able to seize a large area of Jizhou, so that Yuan Shao will no longer be able to fight with us in the field. At that time, Yuan Shao could only stick to Jiancheng, and Jizhou would have Yecheng, Nanpi and other places left to rely on.

The rest of the land that is not in danger to defend, as long as Yuan Shao's field battle is not an opponent of our army, it will inevitably be captured by us. And now it is the end of March, and by the time our army starts, it must have been April, and May is the winter wheat harvest season.

Our army fought a fierce and arduous battle last year, mainly due to the shortage of military rations. If we can enter the land of Jizhou before the winter wheat harvest, because the grain is to the enemy, then our army will be stronger and Yuan Shao will be weaker, and the situation of victory and defeat can be regarded as a certainty. ”

Xun Yu in history, at this time, should be dedicated to suggesting Cao Cao's strategy to fight the battle of Cangting. Obviously, this is because there have been subtle changes in the trend of history, and Xun Yu has also adapted to the times, improvised to the situation, and thought of a set of strategies that are more suitable for the actual situation at the moment.

As a result, the original "Battle of Cangting" changed from a battle in which Cao's army took the initiative to attack, to a battle in which the enemy was first shown weakness and seduced to fight to weaken a wave, and then defended and counterattacked.

This is quite reasonable and completely in line with IQ logic.

The battle of Cangting in history broke out in March of the sixth year of Jian'an, and it is now late March, and even if it breaks out, it is estimated that it will be April. However, the battle of Guandu in history ended in October of the previous year, and now it has dragged on to the month of Layue.

While the end of the previous campaign was delayed by two months, the latter campaign was also delayed by more than a month, which was very much in line with the needs of all parties in preparing for war.

And Cao Cao's humble admonition, as in the same period of history, played a stable role.

After Xun You's advice, he immediately adopted it all, and asked Xun You for more details:

"Gongda thinks that if our army can successfully seduce Yuan Shao to light the enemy, where will Yuan Shao attack from? Where should our army set up an ambush? Along the Yellow River, the border between our army and Yuan Shao, thousands of miles from east to west, may be attacked everywhere. ”

Regarding this question, Xun You had obviously done his homework before he came, so he didn't think much about it, and immediately added:

"I foolishly thought that if Yuan Shao really took the bait, he would most likely attack the area of Dong'e and Fan County."

Cao Cao: "How can it be understood? ”

Xun You: "There are three reasons: First, Yuan Shao knows that our army is holding on to Liu Biao, so he must know that the main force of our army is assembled on the western front, between Wan, Luo, and Yingchuan. If Yuan Shao still launched an offensive on the Yuzhou side of the Western Front like in the Battle of Guandu last year, the main force of our army would return to reinforcements quickly. Yuan Shao may not be able to grab enough time to expand the results first, so he will definitely choose the Yanzhou side of the Eastern Front to attack.

Second, in the case that Yanzhou has been selected on the eastern front, Yuan Shao can also be further screened from the four counties of Taishan County, Jibei County, Dongping County, and Dong County. The eastern county is closer to the western line, and the cities of Puyang and Juancheng are strong, so Yuan Shao will probably not choose. Although Taishan County is the farthest, the terrain is rugged, which is not conducive to rapid advancement. In a compromise, it is naturally the most suitable for Dongping County and Jibei County.

Third, Ming Gong Ke still remembers that seven years ago, when Ming Gong went on an expedition to Taoqian in Xuzhou, Lu Bu attacked Yanzhou, and Ming Gong was once beaten by Lu Bu to only Juancheng, Dong'e, and Fanxian Three cities, relying on Wenruo and Zhongde to design and defend completely.

Yuan Shao also knew about this past, and knew that these three places were the throat nodes for Ming Gong to keep Yanzhou. Therefore, he stationed soldiers and horses in Cangtingjin opposite Dong'e and Fan counties and on the north bank of the Yellow River all the year round, and built a water village. Now that we want to attack the two counties of Dongping and Jibei, the two counties that are on the verge of the Yellow River are the first to bear the brunt. ”

After Cao Cao listened to Xun You's overall reasoning, his eyes also narrowed into a slit, revealing a bit of ruthlessness, a vicious strategy to lure the enemy deep and blossom in the center had already taken shape in his heart.

"In this way, it is best, Lone will let the famous generals guard Dong'e and Fan County, well, Juancheng can also be guarded. Then pretended that the three counties along the river in Yanzhou were empty, and lured the Yuan army stationed in Cangting to enter, but these city defenders insisted on holding on to the death and did not surrender for a long time, attracting Yuan Shao. When my main force outflanks Yuan Jun in a roundabout way, then the inside and the outside should be combined, and Yuan Shao must be hit hard again! ”

The plan for the Battle of Shinkurtei took shape.

After making up his mind, Cao Cao immediately began to spread false news, and even did not hesitate to panic the Xudu court - he blocked the news of peace talks with Liu Biao internally, and even continued to talk about "increasing troops to defend Yexian, defending the pass of Tongbai Mountain, and blocking Liu Biao from going north."

As a result, some civil officials in Xu Du who were not Cao Cao's henchmen were kept in the valley.

This kind of vicious deception trick that even deceives some people who are not related to himself will be much easier to deceive Yuan Shao.

In fact, when Cao Jun pretended to transfer troops in the direction of Nanyang, every unit that left Xudu was heading towards Yanzhou, always ready to ambush Yuan Shao's invading troops.

At the same time, because of the butterfly effect of the Dong Cheng/Lu Bu incident, Jia Xu, who was forced by Cao Cao to sell his strength to make suggestions, also came up to help Cao Cao and Xun You improve some details after realizing Xun You's plan for Cao Cao.

On the third day after Cao Cao began to transfer troops, Jia Xu met Cao Cao alone and offered a private offer:

"My subordinates have a little bit of foolishness and want to ask Sikong for advice. The subordinates thought that maybe they could let our army's troops in Pengcheng County make a feint, pretending to encircle Wei to save Zhao and attack Liu to save Sun. Then let the garrisons of Dongping, Jibei, and Taishan counties move south to Xuzhou to reinforce the Xuzhou army. In this way, Dongping and Jibei will appear more and more empty, and it will be easier to lure Yuan Shao to take the bait. ”

Cao Cao only sorted out this exhortation a little, smoothed out his thinking, and then adopted it all.

In this way, Cao Cao set up two smoke bombs on the east and west lines to deceive Yuan Shao into "the emptiness of the defense line on the south bank of the Yellow River", the smoke bombs on the western front were designed by Xun You, and the smoke bombs on the east front were designed by Jia Xu.

Although Yuan Shao still has a little bit of resourcefulness under his command now, in the face of Xun You and Jia Xu's joint fraud, coupled with Yuan Shao's relatively closed information, it is really difficult to think of it.
