"Cao Cao annexed the four states of Hebei, and his strength increased dramatically, so I should also prepare to form an alliance with Sun Quan and Liu Bei, and everyone will besiege Cao Cao together. Cao Cao is not good at water warfare, and his subordinates do not have generals who are good at water warfare, which is his fatal flaw, as long as he leads his troops south, he will definitely suffer a crushing defeat. However, before leading the troops south, Cao Cao will definitely try to kill me Liu Yu first. Liu Yu muttered.

As early as more than a month ago, Sun Ce was assassinated during the Dantu hunt, although he bravely fought back against the assassins, but unfortunately he was stabbed in the abdomen by one of the assassins, and half a month later, the wound became infected and died in Jianye. Before his death, his younger brother Sun Quan succeeded Jiangdong, so Jiangdong is now Sun Quan in charge.

Guanzhong is guarded by Tongguan, the first male pass today, and Liu Yu is not afraid of Cao Cao's attack at all.

Just as Liu Yu thought, after annexing the four prefectures of Hebei, You, Merge, and Qingzhou, after about a year of recuperation, Cao Cao began to prepare to attack Liu Yu again.

Countless grains and grass were transported to Hongnong and Luoyang for stockpiling, and a large number of Cao soldiers were also transferred to Hongnong and Luoyang.

The mountain rain is about to come and the wind is full of buildings, whether it is Guanzhong or the people of Xudu, they all feel the dense war clouds, and feel that a big war that is about to break out is no less than the battle of Guandu.

Man Zhong came to report: "Lord, Cao Cao has gathered 450,000 troops in Hongnong and Luoyang, and there is still an increase, and it is estimated that it will eventually be no less than 500,000 troops!" ”

Liu Yu was not flustered: "With an army of 500,000, Cao Cao really looks up to me." ”

Guo Jia also smiled fearlessly: "This is a battle that is no less than the Battle of Guandu, or even better than the Battle of Guandu." ”

After Cao Cao annexed Yuan Shao's territory, his army reached more than 700,000, but it was also Cao Cao's limit to mobilize 500,000 troops to attack him.

Chen Gong said: "Although Cao Cao has many soldiers, there are also 400,000 troops in the main public relations, and they have solved Qiang and Di, and they have no worries, and they can completely transfer 300,000 troops to meet the enemy, and there are Tongguan moats, so they are not afraid of Cao Cao at all." ”

In the past, the million-strong army of the six countries knocked on the pass, but they could not break through the Tongguan Pass to destroy Qin, although Cao Cao had an army of 500,000, but how could he do the Tongguan Pass.

Liu Yu nodded and said: "What Gongtai said is extremely true, and I don't think that Cao Cao can break through my Tong Pass and kill me in the pass." ”

Jia Xu suddenly smiled and said: "Lord, I don't think Cao Cao is unaware of the danger of Tongguan, but he may not be sure of breaking through Tongguan." ”

Liu Yu was stunned for a moment, and didn't think that Jia Xu was opening his mouth. If Guo Jia is not only smart, but also has a greater direction and strategy and is good at calculating people's hearts, then Jia Xu is more good at anticipating the enemy's opportunities.

After thinking about it, Liu Yu asked, "Why did Wen He say this?" ”

Jia Xu smiled and explained: "The strong attack on Tongguan must be difficult to break, but if there is a response, what if it collapses from the inside?" Even if there is no internal response, you can bypass Tongguan, cross the Yellow River from the east of the river, and directly enter the pass. ”

Liu Yu, Guo Jia and others all pondered.

Guo Jia said: "The Yellow River in the north of Tongguan is turbulent, and there is no large-scale beach crossing, and it can only cross one or two hundred thousand people at most every day, plus it is difficult to transport grain and grass. ”

In the past, the six countries attacked Qin, why they attacked from Tongguan every time, it was because of the limitations of the Yellow River in the north of Tongguan, and to break through Tongguan, internal response was the most ideal.

Chen Gong interjected: "In the battle of Guandu, Yuan Shao was defeated by Cao Cao because of Xu Yu's rebellion, he was treacherous, coerced the court for righteousness, and made good use of this move, and the lord really had to guard against it." "If you want to say that you have the worst impression of Cao Cao, no one can compare to Chen Gong, and the one who doesn't want to see Cao Cao win the world is also Chen Gong, so Chen Gong will smear Cao Cao whenever he has the opportunity.

Liu Yu also knew that Cao Cao was treacherous, and Liu Yu did not dare to be careless against Cao Cao.

Suddenly thinking of something, Liu Yu's eyes flashed with coldness.

That night, Liu Yu recruited full favor again, and asked him to closely monitor Han Sui, Ma Teng, and even Zhang Lu, if there is anyone under his command who has some status and is easy to be bought by Cao Cao, there is no doubt that these three people, Zhang Lu is more likely, but Han Sui and Ma Teng may not be, these two people once ruled Liangzhou, although he was defeated and surrendered to him that year, but there are still many old generals of the two in the hundreds of thousands of troops in Guanzhong

Full Favor is worthy of being the first cool official and intelligence leader of the Three Kingdoms, Cao Cao has him in history, no matter how Emperor Han Xian and Dong Chengfu conspired with that group of ministers, they couldn't come up with any tricks.

Soon Man Pet found out the clues, Han Sui and Ma Teng have met with unknown people recently, especially Han Sui has more times, and Man Pet also monitored that Han Sui had a secret letter intended to be sent to Xu Du.

Man Pet did not hesitate at all, and immediately set out to intercept it, in history, Man Pet could even stop the extremely secret edict of clothes and belts, and Han Sui's secret letter was naturally difficult to Xu Du.

Liu Yu was furious after reading the secret letter intercepted by Man Chong: "Han Sui traitor, he felt that I didn't reuse him, so he was rebelled by Cao Cao, and was ready to oppose me and vote for Cao Cao, okay, very good!" ”

Liu Yu's most trusted advisor was undoubtedly Guo Jia, and after receiving this secret letter from Han Sui, he summoned Guo Jia alone to discuss it.

"Bonghyo, what do you think?" Liu Yu asked Guo Jiadao.

Guo Jia thought for a while and said ruthlessly: "If you fight Cao Cao in a decisive battle, you can defeat Cao Cao in one battle." If you just want to stick to Tongguan, you can kill it immediately! ”

Of course, Liu Yu is not ready to fight Cao Cao, even if he will defeat Cao Cao once, he will not give Cao Cao a hundred thousand soldiers, and it is impossible to kill Cao Cao and swallow Cao Cao's territory, he also wants to wait for Cao Cao to conquer Liu Biao, Liu Bei, Sun Quan, and Sun Quan in the south, and Sun Quan, Liu Bei, etc.

When it is good to hold Tongguan, if you can't attack the pass, Cao Cao naturally considered going south first, and then the opportunity for the alliance will come.

"In that case, then kill them immediately!" Liu Yu said coldly.

asked Lu Bu to be called, and ordered Lu Bu and Man Chong to lead troops to surround Han Sui's mansion and capture Han Sui. The reason why it is Lu Bu is because Liu Yu feels that Lu Bu is the most experienced in this kind of thing of stealing people from his family, after all, when he followed Dong Zhuo, Lu Bu often did this kind of thing.

Lu Bu then rode a red rabbit horse, held Fang Tian's halberd, and led a thousand soldiers to Han Sui's mansion with Man Chong. House

Although Lu Bu is now almost fifty years old, old, has no son, and after the defeat of Xuzhou, he has no mind to compete for hegemony, and just wants to be an ordinary general who does not need to worry too much, but his temperament will not change, and he still has the pride of the world's number one fierce general.

Lu Bu didn't say a word of nonsense, he directly broke into Han Sui's mansion, and those who stood in the way were ruthlessly killed!

"Poof!" Fang Tian waved his halberd and killed two more people.

When Lu Bu and Man Chong broke into the inner hall, Han Sui finally appeared.

Han Sui accused: "Lu Bu, are you rebelling? ”

Lu Bu sneered: "Han Sui, you want to take refuge in Cao Thief and betray the lord, the crime is unforgivable, and the lord ordered me to arrest you." ”

Han Sui was shocked, turned around and wanted to escape.

However, in front of Lu Bu, the world's number one fierce general, where could he escape, he was slapped in the chest by Lu Bu with a halberd, vomited blood and fell to the ground, and was then captured by the soldiers.

After Lu Bu and Man Chong captured Han Sui, Liu Yu ordered him to be beheaded.

When Ma Teng learned that Han Sui had been beheaded, he trembled in horror and came to ask Liu Yu about it.

Liu Yu still had the letter that Han Sui was going to send to Xu Du in front of Ma Teng, and said coldly and meaningfully: "If people don't know unless they do anything, Han Sui wants to betray me, and he should be punished!" ”

Ma Teng's hands trembled a little, after reading the letter, he knew that this was ironclad evidence, Han Sui was innocent of death, and when he looked up and saw Liu Yu staring at him coldly, Ma Teng breathed in his heart and was very panicked.

Liu Yu said: "Ma Teng, the sentence just now is not only for Han Sui, but also for you, if it weren't for Ma Chao's sake, Han Sui's fate would also be yours." ”

Ma Teng's face turned pale and he almost fell to the ground, it seems that Liu Yu also knew that Cao Cao's people also wanted to plot against him when they found him, and his biggest mistake was that he did not report it to Liu Yu in time afterwards, indicating that he may not have the same thoughts as Han Sui in his heart.

Liu Yu said to Ma Teng earnestly: "Meng Qi is a rare fierce general in the world, with him, I will achieve a great cause, your Ma family is a prince, you should remember!" ”

There are a lot of fierce generals around him, it is impossible to reuse people like Han Sui and Ma Teng, Han Sui's betrayal, Liu Yu is not too surprised, but Ma Teng has Ma Chao behind him, and he is extremely sorry for Ma Chao and Liu Yu, this is to tell Ma Teng that even if he can't be reused, but his son Ma Chao can be reused, if he achieves hegemony in the future, Ma Chao is enough to make his Ma family beautiful, and Ma Teng wants to stick to his duty.

Ma Teng trembled and bowed his head silently, this was listening to Liu Yu's words.

Coming out of Liu Yu, Ma Teng's body was still trembling involuntarily, and he met his son Ma Chao at the door of his house.

Ma Chao saw that his father Ma Teng was full of strangeness, and he asked, "Father, why is this like this?" ”

Ma Teng said to Ma Chao: "Meng Qi, the lord is benevolent and righteous, you should be loyal and assisted, and our Ma family will rely on you in the future." ”

Ma Chao doesn't know why, but Ma Teng knows that he has accepted his fate, he used to be one of the two masters of Liangzhou, and he is a hero, he is actually not willing to be reused under Liu Yu, and he also had rebellious thoughts, but now he doesn't, at least he still has a son Ma Chao, and the Ma family will have a place under Liu Yu in the future.

"If the father doesn't say it, the child also knows that the lord is the master, and the child will be loyal and assisted." Ma Chao didn't quite understand what Ma Teng said, but he said to Ma Teng.

Ma Teng nodded, not wanting to say more.

……

Cao Cao had already arrived in Luoyang, only to hear that Han Sui was beheaded by Liu Yu.

He gritted his teeth and said unwillingly: "Liu Shimin is really treacherous, and he actually recognized Han Sui in advance, which makes my internal responsibility gone, and Tongguan is not easy to break!" ”

Although he destroyed Yuan Shao and swallowed the four states of Beihe, Cao Cao has always regarded Liu Yu as his lifelong enemy, and his greatest wish now is to attack Guanzhong and destroy Liu Yu.

Tongguan since the Warring States Period, the five countries have repeatedly combined to attack Qin have been blocked by this pass, it has always been regarded as the world's first Xiongguan, if there is no internal response, relying on a strong attack alone, Cao Cao really does not have much confidence to break through Tongguan and kill into the pass.

Of course, the army has been mobilized, the grain and grass have also been transported to Luoyang, Hongnong line, and he also came to Luoyang, Cao Cao could not retreat without trying, and the strong attack on Tongguan was already like an arrow and had to be sent.

In August of the seventh year of Jian'an, Cao Cao personally led 500,000 troops to Lintong Pass and attacked Tongguan.

Even attacking more than a month, also tried to break through from the north of the Yellow River in Tongguan, but failed, and finally Cao Cao even ordered some tigers and leopards to participate in the siege as foot soldiers, but also failed to break through Tongguan and enter the pass, but lost 50,000 or 60,000 soldiers before and after, and ran out of grain and grass.

At this time, news came from Jingzhou.

"What, Liu Bei's weaver and peddler also dare to take advantage of my attack on Tongguan and intend to threaten Xu Du with Liu Biao?" Cao Cao was furious.

Nominally to prevent Liu Bei and Liu Biao from attacking Xudu, Cao Cao finally withdrew from Tongguan and returned to Xudu.

Tongguan, seeing Cao Cao's retreat, Liu Yu also breathed a sigh of relief, mobilized 300,000 troops to defend Tongguan for a month, he also killed and wounded 20,000 or 30,000 soldiers, and the grain and grass accumulated in Pingqiang and Di for a year were basically consumed, Cao Cao retreated at this time, it was best.
