On the city of Xudu, Guo Jia looked at the dense army below, and there was no fear in his eyes.

Just now, he only felt that his thoughts were like springs, and in an instant, many schemes were born in his heart, and each of them could resolve the danger in front of him.

It is precisely because of this that he will call Cao Anmin for the first time and let Cao Ang come to discuss the military.

Although he didn't know why Cao Ang left suddenly, Guo Jia knew that once Xu was broken, this would be a huge blow to the Cao family, so he knew that Cao Ang would never be able to watch such a thing happen.

In fact, it was true, accompanied by a burst of horses' hooves, surrounded by Cao Anmin, Cao Ang also hurried to the city wall and saw this Jia Xu and Guo Jia.

At this time, when the two of them saw Cao Ang coming, they also showed respectful eyes, and Cao Ang looked at these two people with a little doubt in his heart.

Although Cao Anmin was using the unparalleled power to capture the black-clothed assassin at that time, Cao Ang could still see the other party's strength, but after Cao Anmin stopped giving orders, the unparalleled power on his body also dissipated, no different from an ordinary person.

At the moment, Guo Jia and Jia Xu are both strategists, God knows when they will exude unparalleled power, or if there is unparalleled power, Cao Ang is also a little skeptical.

So after hurrying to the city wall, Cao Ang also looked at the two carefully.

Among them, Jia Xu didn't see anything unusual because he had joined Cao Ang's side for a short time and was low-key.

However, Cao Ang was able to see Guo Jia at this time, but his face showed a strong joy.

This Guo Jia is not a frivolous person, if it weren't for something huge happening, he would never have shown such an expression, Cao Ang also knew in his heart that maybe this Guo Jia had obtained unparalleled power!

"Fengxiao, I heard Cao Anmin say that you already have a plan in your heart?"

Seeing that Guo Jia's face was full of joy, Cao Ang was also a lot relieved, and he couldn't wait to ask after stepping forward.

And after Guo Jia heard Cao Ang's inquiry, he also nodded with joy on his face.

"Childe came at the right time, and I'm afraid that the plan won't be implemented if it's too late!"

Hearing such words, Cao Ang couldn't help but be a little puzzled, and when Guo Jia saw this, he didn't continue to hide it at this time, and directly took out a map from his arms.

Although the ink has dried on this map, there is still a smell of ink stains, and it is not difficult to guess that this may be painted by Guo Jia not long ago.

After seeing this map, Cao Ang was immediately stunned, just because he really couldn't understand what Guo Jia had drawn.

"Fengxiao, is this difficult...... Formation? ”

At this time, in front of this Cao Ang, there was a drawing like gossip, on which were also written the words "life, death, and rest", and he didn't understand the formation, so after reading it, he didn't understand what Guo Jia meant.

Seeing Cao Ang's inquiry, Guo Jia also nodded excitedly at this time, and still explained for Cao Ang.

"Childe, please see, this is a combination of the landless horse formation and the white bird formation, on the one hand, you can set up a maze formation, so that Liang Xing doesn't know how many people there are in our army, and on the other hand, you can also join forces to attack Liang Xing's weak place!"

When Guo Jia talked about the formation in front of him, his face still showed a deep excitement, as if he was looking at the most proud thing of himself.

It's just that when he said such words, he was the only one who was quite excited, and Jia Xu and Cao Ang were full of doubts.

"Bonghyo, you mean let's set up a defense? Is it to go out of the city to defend? ”

Although Cao Ang didn't know what Guo Jia meant, he was not a fledgling person, he knew that since he was going to set up a formation, he naturally needed a vast place, in this situation of less defense and more defense, did Guo Jia still have to go out of the city to set up a formation?

Thinking of this, Cao Ang also shook his head in his heart, if this was really the case, he didn't dare to make a decision easily.

Hearing Cao Ang's inquiry, Guo Jia also shook his head with a smile at this time.

"Childe, rest assured, after this formation has been improved by Fengxiao, combined with the construction of Xudu's houses, we can defend normally first, once Xudu City is broken, this formation will be broken in this city, and only less than two thousand people are needed to trap Liang Xing's five thousand troops!"

Guo Jia's words were full of confidence, and after hearing such words, Cao Ang seemed to be moved, and his face also showed joy.

If it is a formation to defend after the city is broken, then it may still be used, after all, this Liang Xing army attacked Xudu, if you don't want to pay a huge price, this is absolutely impossible.

After actually entering the city, I'm afraid it would be good to have 3,000 people.

If there is a formation to be performed in the city at this time, it is also a good proposal.

It's just that just as Cao Ang proposed to use this formation, suddenly he seemed to think of something, and then shook his head again.

"Although Fengxiao said that there is a formation to help, but at the moment, the defenders in the capital city are afraid that it is too late to learn this formation!"

Cao Ang knew that no matter what the formation was, if there was no close cooperation, it was very easy to have flaws, and if the flaws did not be made up for as soon as they appeared, it was very likely that they would affect the whole body.

At this time, where is the time to temporarily use the formation of Buddha's feet!

Listening to Cao Ang's words with a little disappointment, Guo Jia immediately shook his head with a smile.

"Haha! Don't worry, Childe, before you arrived, Feng Xiao had already called all the centurions and taught them how to use the military flag, as long as these centurions commanded by the flag, they could quickly arrange this formation! ”

In this Guo Jia's words, there was still a thick message, and after he finished speaking, there was still a cold glint in his eyes.

"And as long as this Liang Xing army enters the city of Xudu, when the time comes, under this chaos, if the prince wants to get rid of others, he only needs to open a corner of this formation, and then the Liang Xing army will be able to enter the city along the formation!"

Kill with a knife!

Don't look at this Guo Jia who doesn't look very serious on weekdays, as if he is indulging in wine, but at this time of crisis, his face has become serious.

"Right now, the princess of Wannian is poisoned, although her life is hanging by a thread, but after all, it is still a scourge, as long as the prince places the princess of Wannian, and when the time comes, Fengxiao will be in the middle of the dispatch, and she will definitely be able to die in the chaos!"

As soon as he said that, Cao Ang was immediately stunned, as if he didn't expect Guo Jia to have such an idea.

Just as he was about to explain, a joking voice came.

"Feng Xiao is so vicious, are you really not afraid of being punished by God and dying young?"
