Cao Cao led his army back to Xudu.

Cao Ren, who was guarding Xudu, came to meet Cao Cao.

Cao Ren said: When Liu Yu saw his lord return to Xudu, he had already returned to Guanzhong.

Cao Cao said angrily: Liu Shimin despises the court and helps Yuan Shao, but is a rebel. I will definitely attack him!

He was very angry that Liu Yu first sent Guan Yu to help him defeat Yuan Shao, and then sent troops to go east and pointed directly at Xu Du, forcing him to return from Hebei, giving Yuan Shao a chance to breathe.

Xun You persuaded: Lord, Liu Yu is in Guanzhong, and has dangerous controls, so it is not easy to attack, so he still insists on annexing Hebei.

Cao Cao's intention to attack Liu Yu was firm, and he said: If he did not attack Liu Yu, how could I feel at ease to annex Hebei?

Xun You and Cheng Yu looked at each other and knew that since Cao Cao had made a decision, he would not change it, so he stopped talking.

Five days later, Cao Cao formed a 100,000 horse army, 250,000 infantry army, and a total of 350,000 troops to Tongguan to attack Liu Yu.

Liu Yu was not surprised to learn that Cao Cao led his army to fight. Although he had only 150,000 troops placed in Tongguan, less than half of Cao's army, he was not worried that Cao Cao could break through Tongguan in the danger.

When Cao Cao led his army to arrive, Liu Yu confronted Cao Cao on the Tongguan city tower.

Liu Yu asked loudly: Why did Meng De attack me?

Cao Cao was furious. You, Liu Yudu, had done something before, and now he still had the face to ask why he was attacking him?

Liu Shimin, I respect you as a hero and ask Your Majesty to appoint you as "Qinhou" and let you rule Guanzhong and Liangzhou, but you help Yuan Shao, attack me, Hongnong and Luoyang, and rebel against the court, and I will destroy you!

Liu Yu sneered, Cao Cao had such a big face, saying that he rebeled from the court?

Cao Mengde, I am a relative of the Han Dynasty. Your Majesty respects me and calls me the "Uncle Uncle" and the clothes and belt edict. Who in the world knows that you, Cao Mengde, hold Your Majesty hostage, you, Cao Mengde, is the prime minister of Han, but you, is actually a traitor of the Han Dynasty. You dare to call the "Court"? The person who rebels the court should be you, Cao Mengde! Liu Yu cursed.

Cao Cao was extremely angry. At this moment, he hated Emperor Liu Xie deeply. He did not do it. He even took advantage of his unpreparedness to do such a thing, which made him lose his righteousness in front of the princes of the world. If there was no righteousness, what would he still support Liu Xie?

Of course, no matter what I think, Cao Cao could not really kill Liu Xie, the Han emperor. Even if he was just the nominal emperor, he could still borrow some of the righteousness of the court.

I felt deeply that I could not get any result when I continued to pull it off with Liu Yu. Cao Cao stopped talking nonsense. He drew his sword and ordered angrily: Attack the city, I want to flatten Guanzhong and kill Liu Yu’s rebel!

Cao's army began to attack the city fiercely.

Liu Yu was personally in charge of Tongguan, with an army of 150,000 and many generals. Cao Cao would never have been able to break through Tongguan without paying more than three or four times the price of death and injury. It was obvious that Cao Cao did not have more than four times the strength of the troops.

Cao Cao attacked for half a month, and suffered tens of thousands of casualties, but he was unable to break through Tongguan. He was exhausted with food and grass with his army. Unfortunately, Cao Cao had to suspend the attack and retreated to Xudu.

A month passed soon, and news came from Hebei that Yuan Shao died of illness.

In order to compete for the succession, the three brothers Yuan Tan, Yuan Xi and Yuan Shang broke out in internal strife and chaos in Hebei.

Xu You excitedly said to Cao Cao: Prime Minister, this is a good opportunity. We should send troops to the north quickly, eliminate Yuan Tan, Yuan Xi and Yuan Shang, and capture Hebei.

Of course, Cao Cao knew that this was a good opportunity, but Liu Yu was eyeing Tongguan with heavy troops. He was worried that once the troops were sent north, Liu Yu would attack Xudu again east, and then he would have to retreat to defend, which would be futile.

Cheng Yu expressed Cao Cao's concerns: Prime Minister, if he did not try to hold back Liu Yu, he would not sit idly by and watch the Prime Minister capture Hebei.

Everyone was silent.

Cao Cao gritted his teeth and said: I will attack Liu Yu again, and I will break through Tongguan and kill him into Guanzhong and destroy him!

Xun Yu persuaded: Prime Minister, it is not easy to break through the natural trench of Tongguan. In addition, Liu Yu has 350,000 troops, which cannot be destroyed overnight. At that time, he will inevitably waste the opportunity for internal strife between Yuan Shao, Hebei.

Cao Cao sighed and asked: So, what are you good plans?

Xu You's eyes turned. He surrendered from Yuan Shao, so he naturally hoped that Cao Cao could capture Hebei as soon as possible, but he should also use more strategies to make Cao Cao pay more attention to him.

After thinking for a while, Xu You made a plan: Prime Minister, why not use the Qiang, Di Erhu?

Cao Cao was immediately excited, Cheng Yu, Xun Yu and Xun You were stunned for a moment, and they all laughed.

Cao Cao laughed and said: Yes, not bad, the Hu people are fierce and greedy. Liu Yu defeated the Xiongnu last year and attracted the Qiang and Di Erhu as a fear. I should try to make the Erhu rebellious against Liu Yu and restrain Liu Yu in the name of the court.

Everyone made a secret plan and agreed on the strategy.

Chang'an City, Guanzhong.

After learning that Yuan Shao’s death, the three Yuan brothers had an internal strife, and Liu Yu cursed again: What a bunch of things that are not covered by mud!

Jia Xu said: Lord, Cao Cao will not miss such a good opportunity and will send troops to Hebei again.

Liu Yu nodded, but he sneered: Of course, Cao Cao would not miss such an opportunity, but he was also very afraid of my heavy troops stationed in Tongguan, and was worried that once he sent troops in Hebei, I would go east again to threaten Xudu, but I don’t know how he would plan.

Liu Yu will find out soon.

The lord, the Di tribe rebelled against Jincheng County, the Qiang tribes captured Wudu County, and killed General Yang and soldiers came to report.

Liu Yu was furious: It’s a damn person, how dare you rebel against me!

If it is not my race, his heart will be different. Liu Yu never believed in the Hu people. Since he destroyed the Huns, Liu Yu would also be ready to destroy the Qiang Di Erhu one day. However, he did not expect that the Qiang Di Erhu would actually choose to rebel against him at this time, which caught him off guard.

Guo Jia concluded: This must be done by Cao Cao, otherwise the Erhu would not be so on time. No matter what, it is imperative to pacify the Qiang Di Erhu, and I am afraid that Cao Cao will take this opportunity to annex Hebei. By then, Cao Cao's power will be greatly expanded, and Brother Yu is unfavorable.

Liu Yu nodded, but he was not panicked. Once Cao Cao captured Hebei, his power would become extremely powerful. However, he had the defense of Tongguan Tianqian, and resisted Cao Cao to defend Guanzhong and other places without losing. Besides, he had plans earlier. When Cao Cao captured Hebei and his power surged, he and Sun Quan and Liu Bei surrounded and beat Cao Cao together to let Cao Cao know that even if he annexed Yuan Shao, he became the most powerful prince in the world. Facing the beating, he should know why the flower was so popular.

It is imperative to pacify the Qiang, Di Erhu. By then, the Erhu will be pacified and there will be no worries before it can truly fight against Cao Cao.

Three days later.
