Jian'an five years, late spring in March.

While the two armies of Sun and Liu were fighting fiercely on the eastern front, the two counties of Jingzhou, Jiangxia and Changsha, thousands of miles away on the western front, were also surging and the battle clouds were dense.

Zhang Xian, the Taishou of Changsha, like Sun Ce, the former Huiji Taishou, was a powerful local prince who was persuaded by Cao Cao's secret edict.

The benefits that Cao Cao promised to Zhang Xian were as rich as those promised to Sun Ce - as long as Zhang Xian restrained Liu Biao, pulled the flag to crusade against the "anti-thief Liu Biao", and all the land he fell, the imperial court would posthumously recognize it, and seal Zhang Xian as the pastor of Jingzhou in advance.

Even the time when the secret edict was delivered to Zhang Xian was about the same as the time it was sent to Sun Ce, and it was delivered in late February of this year.

It's a pity that Zhang Xian is more cowardly than Sun Ce.

And Liu Biao's blockade and vigilance against Zhang Xian's news are far less than what Liu Bei did to Sun Ce - Liu Biao does not have enough resourceful people around him to help him deduce predictions and set up scams.

He also vaguely felt that Zhang Xian had a situation of disobedience, but he didn't expect Zhang Xian to openly rebel, so he failed to completely block Zhang Xian's information channels for communication with the outside world.

In contrast, on the Yangzhou battlefield, until the moment when Sun Ce rashly raised his troops, he fell for Zhuge Jin's trick to lure the enemy. At that time, Sun Ce thought that Cao Jun had already fought with Liu Bei, and tens of thousands of Cao troops were attacking Shouchun and Xiapi, threatening Liu Bei's Huaisi defense line on the northern front, so Sun Ce's courage suddenly strengthened and dared to jump out.

On the Jingzhou battlefield, Liu Biao never made any deceptions such as "Obviously I haven't fought with Cao Cao yet, but I lied to the people below me that I have already started a fight with Cao Cao" to seduce careerists to jump out.

The more transparent the information those careerists get, the more they are able to see the rabbit and not the eagle.

……

On this day, it was already March 22.

Jiangxia County, the Cheqi General's Mansion in Wuchang City.

After Liu Bei received the secret report from Guan Yu and Zhuge Jin about the war on the Eastern Front early in the morning, he couldn't help but feel anxious.

I paced back and forth in the lobby all morning, and asked people to find Zhuge Liang, Pang Tong, and Xu Shu, and there was something to discuss.

Liu Bei has been fighting for a long time, and he has gathered Zhang Fei, Gan Ning, and more than 30,000 main soldiers who can go out at any time - this number does not include the defensive troops that must be left to guard Jiangxia County, but only calculates the attack troops that can be appropriated at any time, so the scale is already very considerable.

In addition, there is also Zhao Yun, who is still stationed in Lujiang County, according to the original plan, after confirming that all the main forces of the Cao army on the other side of the Huai River have been transferred to fight Yuan Shao, Zhao Yun will also rush to Jiangxia County, and bring about thousands of reinforcements to help Liu Bei to pacify Zhang Xian at a thunderous speed.

Now count the days, there will be about ten more days, and Zhao Yun will be able to come. According to the original plan, Zhao Yun should be the second wave of the Jingnan Campaign, and the first wave was too late to catch up.

Liu Bei has been so well prepared, but Zhang Xian has not taken action for a long time, how can this make Liu Bei not in a hurry?

After a while, Zhuge Liang, Pang Tong, and Xu Shu all arrived.

Liu Bei was not polite to them, and went straight to the point, first pointing to Zhuge Jin's secret report on the desk, motioning them to take a look, while explaining concisely:

"This is Ziyu's secret report, written six days ago, sent to Wuchang from Wuhu water and land relay. The formal negotiations between Yun Chang and Sun Ce broke down, and Sun Ce chose to confront the rebel Wang Shi with Cao Cao's edict. The crime of starting a war will naturally be blamed on Sun Ce. This was nine days ago, March 13. The next day, March 14, Zhou Yu crossed the Yangtze River from Dantu north and attacked Guangling.

Yuanlong deceived the enemy, seduced Zhou Yu to attack, and successfully repelled Zhou Yu's first wave of offensive and won a small victory in the first battle. Ziyu's recital was written after Yuanlong's first battle against Xiaojie. What I'm worried about now is, why didn't Zhang Xian do it for a long time? Sun Ce did it nine days ago! ”

While Liu Bei explained, Zhuge Liang and the three of them also read the letter, and the basic situation was clearly grasped. Zhuge Liang thought about it for a while, and then speculated:

"Zhang Xian's reaction was slow, which was beyond our expectations, maybe it was just that he didn't see the rabbit and didn't scatter the eagle, and he didn't dare to act rashly if he didn't see Liu Biao or the emptiness of our army. The lord doesn't have to worry about this matter, as long as he pushes it with a little trick, it may change within ten days. ”

Liu Bei didn't bother to think about it, since Zhuge Liang said that he had a little trick, he asked directly: "What's the plan?" ”

Zhuge Liang shook the feather fan three times, and lightly pointed to his eldest brother's secret letter: "Let's just plan it, just select part of the content of my brother's letter and leak it." It is said that Sun Ce suddenly rebelled in Yangzhou, and he did not serve the edict of clothes and belts, but the edict of Cao Cao.

Yun Chang and his brother were outnumbered and could not resist, so the lord hurriedly transferred troops from Jiangxia down the river to aid Wuhu and Guangling.

In addition, you can also spread rumors - we didn't just hear about it the day before yesterday that Cao Cao had lost Yanjin and Baima successively, and was retreating to the south and resisting one after another. Then we will preach that Cao Cao has been defeated and retreated to Guandu, and the troops are exhausted, so we will transfer another batch of troops from Wancheng to Guandu.

In this way, if he can deceive Liu Biao, Liu Biao will inevitably covet the emptiness of Wancheng and want to take back this vital buffer place that should belong to him. After all, Nanyang County theoretically belongs to Jingzhou, and Liu Biao, as a pastor of Jingzhou, how can he not want to take Wancheng back?

When Zhang Xiu was supported by Liu Biao as a puppet, Wancheng was indirectly controlled by Liu Biao. It was Zhang Xiu who was betrayed by Jia Xu, and Liu Biao completely lost Wancheng, people are always very impulsive about what should belong to them and have just lost it.

At that time, Zhang Xian heard that our army was going east along the river and was busy dealing with Sun Ce, and Liu Biao went north to recapture Wancheng, so he would definitely not be able to hold back, and our army would be famous. ”

"Brilliant plan! Just do it according to the gentleman's wishes! Our army in Jiangxia should further show weakness and show the enemy to be weak! Liu Bei heard the high-fives and admired, and directly adopted Zhuge Liang's idea in its entirety.

Because of Zhuge Liang's plan, he didn't tell a lie at all, what he said was the truth. Zhuge Liang just made a time difference, said what he wanted the other party to know earlier, and put off what he didn't want the other party to know a little later.

The kind of content that is completely real and only has a slight time difference is the most unlikely to be recognized.

Liu Bei's camp has always been in this style of blocking the information of the princes of the Southern Self-Reliance faction.

This is also the reason why Zhuge Jin later wanted to block Sun Ce and Zhou Yu's exchange of technical lessons and lessons with Cao Cao, and it was difficult to block it - Zhuge Jin's previous manipulation of Sun Ce's cognition made him aggressive, which was time-sensitive.

What happened in March was naturally known to Sun Ce in April. But Zhuge Jin didn't want him to know, so he could delay it until May or June, and in the end Sun Ce would still know the truth, but it was too late, and he was fooled.

In contrast, the exchange of technical lessons learned is not time-sensitive, and it is still valuable if a technical experience is transferred a month or even two months late.

Based on Zhuge Jin's information blockade of Sun Ce, if Zhou Yu had collected data in July and sent a secret envoy to infiltrate and report to Cao Cao, then the previous waves might indeed be seized and intercepted by Zhuge Jin.

But that only made Cao Cao unable to get this information in August and September, and it was impossible to delay it forever. If it drags on until October, Cao Cao will still know what he should know.

Moreover, the diffusion of technical information, compared with the diffusion of political and military intelligence, has another convenience, that is, technical information has strong verifiability and reproducibility.

When Cao Cao sent a secret envoy to send a letter to Sun Ce, it was easy to goof, because Cao Cao was sending political and military information, and if this information was not conveyed by a heavyweight like Hua Xin, Sun Ce would not have believed it.

Any cat or dog ran to Sun Ce and said, "Cao Gong named you Yangzhou Mu", and Sun Ce would only drive him out as a madman.

But the follow-up information that Zhou Yu wants to send to Cao Cao can be sent by a worthless person like mercury, even if he is caught by Zhuge Jin, it doesn't matter.

Anyway, as long as one person delivers it, Cao Cao will arrange for someone to verify it to see if Zhou Yu's statement can be reproduced, and he will know whether it is true or false, which does not require identity endorsement.

Even if Newton's three laws are recited from the mouth of a parrot, they are still valid.

……

It's a little farther, anyway, Liu Bei currently has a full understanding of the essence of the Zhuge brothers' "fighting cognitive time difference combat".

The tricks used by Zhuge Jin to deceive Sun Ce were transferred to Zhuge Liang to deceive Zhang Xian, and he was also familiar with it.

In particular, Zhang Xian still lacks high-IQ strategists around him, which makes it easier for Zhuge Liang to succeed.

On March 23, the disinformation dissemination system of Liu Bei's camp spread the news he wanted to spread step by step according to Zhuge Liang's deployment.

Deceiving Liu Biao with one hand and deceiving Zhang Xian with the other, both hands should be hard.

Liu Bei didn't ask about any process, progress, or urging, he was fully assured of Zhuge Liang's work, and believed that Zhuge Liang would get it done as soon as possible.

However, Zhang Fei, who was recruited by Liu Bei in Wuchang in a low-key manner in advance, was a little breathless.

In order not to alarm Zhang Xian, Zhang Fei was transferred to this matter was strictly confidential, and when Zhang Fei's troops arrived, they were not allowed to fight, and they still entered the city at night.

After arriving in Wuchang, Zhang Fei was also restricted from his movements, and could only live in Liu Bei's Wuchang Marquis Mansion, and he could not step out of the door, lest he cause trouble and leak out.

I heard that the second brother and Ziyu had already started to fight Sun Ce, and they were fighting well, but they had no fight in Jiangxia for the time being, so Zhang Fei found Liu Bei and asked for instructions:

"Big brother, if Kong Ming's side delays and Zhang Xian doesn't give us an excuse to attack, then let us go down the stream to support the second brother first, and help beat Sun Ce to his stomach and come back!"

Fortunately, Liu Bei still has absolute control over Zhang Fei: "I'm not in a hurry, what are you anxious about!" Is the movement of the army child's play? The 1,200-mile Yangtze River waterway from Wuchang to Wuhu was a round trip on the march, and no battle was fought, so it took more than half a month.

If you delay a little longer, that's more than a month! Kong Ming said that it will take more than ten days at most to see results here, so you can hold it for me! It's a big deal to wait for Zhang Xian to show his head, and let you take the lead! ”

When Zhang Fei heard this, he suppressed his eagerness to fight.

Zhuge Liang's calculation was really accurate, and on the eighth day after the two-pronged deception, on the first day of the fourth month, Liu Biao really couldn't hold back. Hearing that Cao Jun continued to send Wancheng's soldiers and horses to Guandu to defend it, and the old department left by Zhang Xiu was drawn to nothing, Liu Biao finally decided to go north and get back what should have belonged to him.

However, Liu Biao is not stupid, he also knows that there will definitely be careerists in his rear, so he mobilized Liu Pan, Huang Zhong, Wenpin and other departments to go north to Wancheng, and at the same time, he issued a gag order internally to let everyone keep a low profile.

He hoped to make a lightning strike, and by the time the others found out that he had sent troops, he had already created the established fact and cooked the raw rice.

It's a pity that Liu Biao wants to keep it secret, and Zhuge Liang will help him leak it.

So four or five days after Liu Biao sent troops, Zhang Xian in Changsha knew that Liu Biao had sent troops.

"God help me! Liu Biao transferred Liu Pan and Huang Zhong from Nanjun to the north, wanting to take back Wancheng. Liu Bei also transferred Jiangxia's main force to Wuhu, wanting to destroy Sun Ce first. Nanjun and Jiangxia are all empty of troops, and if you don't do it at this time, when will you wait! ”

On the sixth day of the fourth month of April, Zhang Xian convened all his subordinates and generals in Changsha Taishou Mansion, and announced that he responded to the edict issued by the Xudu Imperial Court and Cao Sikong in the name of the Son of Heaven, leading Jingzhou Mu to cross the river and attack Nanjun in the north!

"I am under the edict of the Son of Heaven and lead the Jingzhou Mu to crusade against the anti-thief Liu Biao! You must work hard to get rid of thieves for the country! Wuling Jin Taishou and Guiyang Zhao Taishou also decided to listen to my orders, and they will be edicted together! Don't worry! ”
