After Guo Jia's plan was released, not only Cao Cao was confused, but all the generals present also rushed to the doubt.

Because, even if three or five thousand people can really sneak into the vicinity of Wuchao, it will inevitably be difficult to capture Wuchao.

Before everyone could ask questions, Guo Jia took the initiative to explain: "Lord, the thousand-mile dike is destroyed by an ant hole. Don't forget, do we have a trump card inside Yuan Shao?"

Who is Guo Jia talking about? Of course, it is Xu You. Xu You had already secretly communicated with Cao Cao's songs early on, but it's a pity that Yuan Shao did not bring Xu You when he went to war. Therefore, this trump card has not been moved.

When he heard Guo Jia mention Xu You, Cao Cao asked quickly: "Fengxiao, I wonder what you want Xu You to do for us?"

Guo Jia smiled slightly and said to Cao Cao: "Let Xu You help us find out who the official in charge of the guards of Wuchao is."

"When our people sneak in, we can ask Xu You to contact the big family near Wuchao to go to the army. At that time, our people will be caught off guard by mingling among the army's army."

After hearing Guo Jia's plan, Cao Cao couldn't help but lit up. If this is the case, this plan is feasible.

It is common for labor to work in this era. After all, for the rich local households, it is like finally having the opportunity to curry favor with the princes.

Moreover, Xu You is an important official under Yuan Shao, and he is also a child with Yuan Shao. If the man who is working hard on the name of Xu You, it will definitely not arouse suspicion.

"With the filial piety, I, Cao Mengde, is really like a tiger!" Cao Cao couldn't help but sigh.

Cao Cao immediately ordered his subordinates to send a letter to Xu You, ordering him to help inquire about the news about the Wuchao guards first, and then wait for an opportunity to cooperate with him.

After having the plan, Cao Cao was not in a hurry. After all, such things should not be too hurrying.

In a blink of an eye, more than a month has passed.

Among them, Cao Cao and Yuan Shao fought several battles. However, they were all thunder and raindrops, and did not cause too much casualties to both sides.

Yuan Shao was waiting, he was waiting for Ma Chao to break through Tongguan, and came to Cao Cao's rear, and then the two surrounded Cao Cao.

Cao Cao was also waiting. Cao Cao was waiting for his plan to lay the groundwork step by step, and then he was able to defeat Yuan Shao by surprise.

These two people have their own plans and their own ideas. At this time, it only depends on whose plan can succeed.

Cao's army camp.

Cao Cao's tent.

"Report..."

"The military information on the front line is urgent, please take me to see the King of Wei, hurry up." In the middle of the night, Cao Cao was about to sleep when he suddenly heard a loud noise outside.

Cao Cao frowned, but didn't say much. He hurriedly put on his clothes and came outside.

"Where is the military information coming from?" Cao Cao strode outside and asked as he looked at the dusty command soldiers.

"Report to King Wei, it's Tongguan!" The messenger said, took out the letter from his arms and handed it to Cao Cao.

When Cao Cao heard that it was the military information coming from Tongguan, he couldn't help but feel a grudge in his heart. Could it be that Tongguan has fallen?

Thinking of this, Cao Cao couldn't help but be frightened. If Tongguan was lost, Ma Chao would be able to drive straight in and head straight to his rear. At that time, Yuan Shao and Ma Chao would attack him from the front and back, and Cao Cao would definitely be defeated.

Cao Cao's head was buzzing at this moment. In the midst of numbness, Cao Cao opened the letter. It was not until he finished reading the contents of the letter that Cao Cao couldn't help but breathe a sigh of relief.

Now for Cao Cao, there is good news and bad news.

The good news is that Tongguan has not been lost, and the bad news is that Yu Jin is injured.

I have to say that Yu Jin is really a general who is good at defending the city. He has been guarding Tongguan for a month, but he has not allowed Ma Chao to move forward at all.

In this month, Ma Chao's attacks, large and small, organized more than a dozen times. However, all of them were blocked by Yu Jin.

Not only did he block the attack of Ma Chao's more than 200,000 troops with a 50,000 troops, Yu Jin also strictly controlled his own casualties.

At this time, the 50,000 troops brought by Yu Jin were still left, with only more than 40,000 casualties.

However, Yu Jin was also unlucky. He accidentally hit the ravine while patrolling the city wall. At this time, he was seriously injured and unconscious.

I am afraid that this Tongguan will not be able to hold on for long. This letter was sent by Yu Jin's deputy general, asking Cao Cao to send a general to command the overall situation.

With this letter, Cao Cao was also very confused. Cao's camp was not without generals, but if we say that there was no one who could beat Yu Jin in the city. Yu Jin could defend Tongguan, but if someone else had changed to him, it might not have been able to defend him.

After thinking about it, Cao Cao felt that if he wanted to defend Tongguan, he had to go in person.

Cao Cao himself was also a general and his ability to command and fight was extraordinary. Moreover, Cao Cao had one advantage in seizing Tongguan, that is, his morale.

At this time, there were only more than 40,000 people in Tongguan City, but there were still more than 100,000 Xiliang Alliance troops outside the city. At this time, it was a great test for the morale of the army in the city.

After all, when facing an enemy who is several times more likely to be with you, anyone will be panicked.

Cao Cao went to Tongguan in person, and told the soldiers in Tongguan that Cao Cao was willing to live and die with the soldiers of the three armies.

Only in this way can the morale of the Tongguan defenders be greatly improved and they can defend Tongguan.

In the interview, their plan to attack Wuchao has been almost done. The front line of Yanjin include Cao Ren, Xiahou Dun, Xiahou Yuan and others, and Guo Fengxiao in literature. Cao Cao is here, and there is no difference between not here.

Thinking of this, Cao Cao became even more determined to go to Tongguan.

"Beat the drum and raise the tent!" Cao Cao ordered the guards beside him.

Cao's army camp.

The Central Army’s tent.

Hearing the drums, although he didn't know what it was like to be promoted to the tent in the middle of the night, in just a quarter of an hour, all the generals and officials of the Cao army gathered in the central army's tent.

Cao Cao looked around and saw that everyone was here, Cao Cao took out the military information from Tongguan and said to the generals: "Emergency military information came from Tongguan, Yu Jin was unconscious when he was shot in an arrow. At this time, there were soldiers but no generals in Tongguan."

When they heard this, all the generals looked at each other. At this critical moment, Yu Jin was caught in a coma, which was not good news.

Once Tongguan is lost, Ma Chao's cavalry will be able to appear behind them in just a few days. At that time, I am afraid that everything will be over.

"I want to go to Tongguan in person, and the war in Yanjin will be held in charge. The military advisor's words are the words of me, Cao Mengde!" Cao Cao said solemnly.

As soon as Cao Cao finished speaking, he saw the Cao army generals kneeling down on the ground like little dumplings.

"King of Wei, the last general asks for battle!"

"I will go to Tongguan at the end!"

"The last general dares to issue a military order!"
