Suddenly, the battalion commander came back and said to everyone: "I saw that the prime minister has been around the city for several days recently, is he making any preparations to attack the city?" ”

One of the soldiers said, "We're all about to suffocate, and we don't know when we're going to strike." ”

Yuyi asked: "Is there a loophole in Nanyang's city defense, the prime minister has found it." ”

When the camp heard this question, they thought to themselves that we had just gotten the news, how could someone know about it so quickly, and they had doubts in their hearts, so they had to find out who asked the question from among the soldiers.

Yuyi knew that he couldn't hide, and he was not afraid, so he immediately stood up.

The battalion commander asked, "Why haven't I seen you before!" ”

Yu Yi hurriedly explained, "I am a recruit just recruited. ”

The battalion commander nodded, thinking that he had indeed lost a lot of soldiers and horses because of the forcible attack on Shouchun recently, and he had also recruited some people to come in, but Yu Yi's performance was not like that of ordinary miscellaneous soldiers, so he reminded: "Don't talk about military aircraft affairs casually, otherwise it will be easy to bring death!" ”

Yuyi nodded quickly, and then returned to the group.

With this news, he went to that place that night, it turned out to be a very deep city, which had been almost buried by Cao Cao with mud and other debris, Yuyi looked at it, and found that the place was indeed very close, and the torches on the city wall could be vaguely seen.

Yu Yi didn't know where the idea came from, so he tied a piece of paper to the back of the flying knife on a whim, and then shot it at the city wall with all his might.

After all, Yuyi's strength was limited, and the flying knife fell down as soon as it reached the city wall, but this movement was enough to attract the attention of the soldiers, they picked up the flying knife, and when they saw that there was still information behind it, they hurriedly reported it to Zhang Xiu.

The piece of paper was very small, and there were only two short words on it, but Jia Xu knew what was going on at a glance, and went to the city wall in person, put down a rope near the direction where the flying knife came from, and then instructed the guards on the city wall, saying: "Soon a person wearing Cao Jun's uniform will climb up, don't be rude, bring him to see me!" ”

Yuyi expected that the time was almost up, and the piece of paper should have been passed in place, so he walked in that direction, saw the rope falling from the city wall, climbed up in one breath, and the soldiers helped it up and took it to see Jia Xu.

Looking at the person in front of him, Jia Xu was a little moved, his face was covered with mud, and there were some wounds on his body, if it wasn't for himself, he would definitely not come to Nanyang.

Jia Xu arranged for someone to prepare a bath bucket, and sent someone to prepare clothes, and then stopped Yuyi, who was about to speak, and said, "You better go to the bath first, and we will talk about the rest slowly." ”

Yuyi was in the mood to take a bath, and soon came out of the shower, saw Jia Xu, saluted, and said: "Master, now that Cao Cao's army is besieging, Nanyang basically has no chance of winning, why don't you run away, you have to put yourself in danger." ”

Jia Xu smiled and said: "Yuyi, you are too worried, I know Cao Cao, there will be no problem, the so-called strong have their own strong players, don't you think this is very interesting?" ”

Yu Yi smiled bitterly and thought: "It turns out that the master is also very clear, but he likes this kind of challenging life, that is, he likes to fight wits and courage with others, and there is really no way for him to escape." ”

So Yuyi changed his mind and asked: "I heard in Cao's army that Cao Cao circled the city three times and filled weeds everywhere, so he was preparing to find a weak place to attack the city." ”

Jia Xu patted Yuyi's shoulder in fear and said, "You are only half right, Cao Cao's trick can't fool me!" After speaking, he hurriedly sent someone to find Zhang Xiu, and he happened to discuss this matter.

After Zhang Xiu saw Yuyi, he thought he was an enemy, so he quickly drew his blade, and under Jia Xu's persuasion, he stopped.

Jia Xu said to Zhang Xiu: "Recently, I saw Cao Cao on the city wall and observed the city for three days, he saw that the color of the bricks and soil in the southeast direction was different from the old and new, and some facilities were also destroyed, thinking that this place would be the weakest place in our city, and he was ready to attack from here, but he deliberately sent people to the northwest to fill in the weeds, creating a momentum of attacking from that place, and tricking us into withdrawing troops to hold the northwest direction, so he would take advantage of the night to enter here from the direction of the southeast corner." ”

Yuyi didn't know about this situation, but when Jia Xu said it, he thought it was still very exciting, so he applauded: "Cao Cao is really scheming, and this voice is really powerful." ”

Zhang Xiu couldn't help but shake her head after hearing this, and asked, "Then what should I do?" ”

Yu Yi specially checked Zhang Xiu's expression on the side, he was indeed very flustered, Jia Xu also enjoyed this feeling very much, and finally Yu Yi understood why Jia Xu always looked for such a person as his assistant, first of all, this person must be a little-known ordinary person, and the other is very important, you must listen to him very much, at that time, Li Xun did not listen to him, and soon failed is such a truth, and then by giving advice to ordinary people, it is better than some clever people, presumably any strategist will have a sense of achievement, And Jia Xu is like this, purely to challenge the difficulty.

Jia Xu looked at Zhang Xiu and said with a smile: "This matter is actually very simple, in a few days Cao Cao has a move, so that the elite troops in the city can be fed, wear light clothes to battle, and then hide in the southeast houses, and then let the people over there pretend to be sergeants, guarding in the northwest direction, and waiting for Cao Cao to climb the city from here with soldiers and horses at night, and when he climbs halfway, we ambush the soldiers, Cao Cao may be able to capture alive." ”

The biggest feeling with Jia Xu is that everything is under control, being able to see the intention from any clue, taking precautions, Yu Yi likes this feeling very much, these practical strategy experience is quite valuable, in just a few sentences, Jia Xu has used two strategies, and Yu Yi is also amazed.

When he entered Nanyang, Yu Yi was still worried about his master Jia Xu, and now, Yu Yi began to worry about Cao Cao, and it seems that everything is under Jia Xu's control.

Outside the city, someone came to report that Zhang Xiu had withdrawn all his troops and placed them in the direction of the northwest corner, and at the same time shouted loudly, hold the city, and the southeast direction was very empty.

Cao Cao laughed and said, "Sure enough, it was my plan!" So he ordered the lieutenant to quietly take out some tools for climbing the city, and only sent troops to pretend to attack the northwest corner during the day, and when he arrived at about the second watch, he led the elite soldiers to sneak in to the southeast direction and cut off the antlers, which was also the route for Yuyi to secretly enter Nanyang.

After entering the city, he found that it was indeed empty and empty, and there was no movement at all, and everyone poured in together, and before they were halfway there, they suddenly heard a cannon shot, and many soldiers were killed from the houses.

Cao Bing was dumbfounded, and hurriedly retreated to the back, behind which Zhang Xiu personally led the soldiers and horses to kill, and attacked from both sides, Cao Cao's troops were defeated, and fled for dozens of miles.
