When night fell, a bright moon hanging in the sky was obscured by large dark clouds, and the whole land was plunged into darkness.

Lu Bu ordered all his troops and horses, and took Song Xian, Hou Cheng, and more than 2,800 horse infantry troops to quietly approach the Cao army camp in the night.

At this time, Zhang Yan was discussing things with Tai Shici, Xu Chu, Niu Jin, and Xu Sheng in the room, when he suddenly heard someone knocking on the door, so he asked Xu Sheng to open the door, and saw Gao Shun and Zhang Liao with panicked faces.

As soon as Gao Shun and Zhang Liao entered the room, they immediately knelt on the ground, hugged their fists at Zhang Yan and said, "Zhang Andong, please save my father-in-law!" ”

"Hurry up, two of you, if there's anything, just get up and say." Zhang Yan personally walked over and helped Gao Shun and Zhang Liao up.

"What's wrong with your father-in-law?" Zhang Yan asked.

Gao Shun replied: "My lord led the army out of the city to attack the Cao army camp, and I tried hard to persuade him, but the lord not only didn't stop, but also left us in the city. That Cao Cao has always been extremely treacherous, how could he let people attack his camp so easily? What's more, the last time the lord acted rashly and went to attack Cao Cao, but he fell for Cao Cao's tricks, not to mention the loss of troops, and almost lost his life. This time, the lord went to attack Cao Cao again, and I was afraid that I would fall for Cao Cao's tricks again......"

Zhang Yan said: "You don't have to panic, I already know about this matter, not only you can't persuade him, but even I can't persuade him." There have been too many things happening in the city in the past two days, first Hao Meng rebelled, and then Chen Gong was killed, and even Mrs. Diao Chan ......"

When he said this, Zhang Yan paused, sighed lightly, and then continued: "Perhaps, Brother Feng Xian couldn't accept what happened for a while, especially the matter of Mrs. Diao Chan, which hit Brother Feng Xian very hard, which made him make such a rash move. However, you can rest assured that I already have a plan to deal with it, but I need the help of both of you! ”

Gao Shun and Zhang Liao hugged their fists towards Zhang Yan and said: "What is Zhang Andong's send, even if he orders, we will definitely act as ordered!" ”

Zhang Yan said: "Okay, with your help, I believe that Brother Feng Xian will definitely be safe and sound." ”

Immediately afterwards, Zhang Yan made some arrangements, Tai Shici, Xu Chu, Niu Jin, Xu Sheng, Gao Shun, and Zhang Liao each had their own division of labor, which was different from each other, but they all obeyed Zhang Yan's orders.

After the order was completed, Zhang Yan ordered the assembly of soldiers and horses, Tai Shici and Xu Chu gathered all the cavalry and followed him to the Cao army camp, while Niu Jin, Xu Sheng, Gao Shun, and Zhang Liao each guarded a city gate, and did not see him come back, no matter who called the city gate, do not open it.

Before leaving, Zhang Yan was still a little uneasy, and instructed Gao Shun and Zhang Liao again, and then led Tai Shici, Xu Chu and three thousand cavalry to leave Dingtao.

After Zhang Yan, Tai Shici, Xu Chu and others left Dingtao, they quietly followed behind Lu Bu's soldiers and horses, but they deliberately kept their distance, just for fear that they would be discovered by Lu Bu.

In fact, his intention is very simple, it is nothing more than throwing stones to ask for directions.

His opponent was Cao Cao, Cao Cao was a famous military strategist in history, and he used his troops like a god, and this time, he was even more head-to-head with Cao Cao, so he became very cautious.

According to his judgment, Cao Cao must be prepared tonight, and may have already arranged everything, waiting for Lu Bu to drill into this big net.

But on the other hand, he really wanted to know whether his judgment was correct.

Therefore, he made such a decision, let Lu Bu be his pawn, to test Cao Jun, if Lu Bu is surrounded by Cao Jun, it means that Cao Cao has already prepared, he just needs to kill from behind and rescue Lu Bu.

But if Lu Bu's sneak attack really succeeded, he could also lead the army to support and attack Cao Cao.

This approach, although it is using Lu Bu, is a bit despicable, but it is also the most effective method.

At the same time, Lu Bu led Song Xian and Hou Cheng to approach the camp of the Cao army, and saw that the camp of the Cao army was lifeless, but the team of night patrols was carried out very regularly.

When Lu Bu saw such a scene, his brows furrowed, but since he came out with his troops, he couldn't return empty-handed, so he chose to wait.

He led his soldiers and hid quietly in a bush outside the camp, just as the moon was dark and the wind was high tonight, which was very suitable for their concealment.

Lu Bu and Cao Cao fought many times, basically losing more and winning less, and suffering losses again and again also made Lu Bu become cautious and did not dare to act rashly again.

After losing Chen Gong, he seemed to have become much calmer and began to know how to think with his brain.

Zhang Yan led the army and quietly followed behind Lu Bu, but he didn't follow tightly, for fear that Lu Bu would find out, so he had to send scouts to the front to investigate.

When the scouts returned, they learned that Lü Bu was waiting outside Cao's camp for the right time, and Zhang Yan also decided to wait here.

I waited for an hour and a half, and waited until midnight.

At that time, the patrol team in Cao's camp gradually became sleepy, and the number of patrols was reduced, and even the interval was getting longer and longer.

After Lu Bu found this, he patiently observed for a while, and finally waited for the situation he wanted.

However, because he almost died at the hands of Cao Cao last time, Lu Bu was also doubly careful, so he was not in a hurry to attack, but let the soldiers rest.

The soldiers were also sleepy, and after listening to Lu Bu's words, they fell to sleep on the spot, and Lu Bu even arranged for people to patrol the night, and as soon as they found any clues, they immediately reported to him.

When Zhang Yan learned that Lu Bu asked his subordinates to rest in place and did not take action, the motor in his head turned around quickly, and he smiled: "I didn't expect Lu Bu to become cautious now, if I guess correctly, he should want to attack before dawn." ”

So, Zhang Yan also asked his subordinates to rest in place and recuperate.

As Zhang Yan guessed, Lu Bu really thought so. In his opinion, the darkness before dawn is the most terrifying.

Because even Lu Bu was afraid that he would fall for Cao Cao's tricks again, if Cao Cao really set a trap, then in order to wait for him to jump into this trap, Cao Cao's army would definitely not close his eyes all night, and when he stayed up until dawn, he would definitely be very sleepy.

Even if Cao Cao didn't set a trap, and the period before dawn was also the time when people slept most well, if he suddenly launched an attack at this time, Cao Jun would definitely be beaten by him and fled.

On this night, nothing happened within a radius of thirty miles from Dingtao City.

However, the people in Dingtao City were so anxious that they didn't dare to sleep, but they couldn't wait for news, which was really tormented.

At three o'clock in the morning, Lu Bu woke up all his subordinates, and at this time it was even darker, and in Cao's camp, those guards were already napping with their weapons.

This time, after Lu Bu was sure that it was the real Cao Bing, not a scarecrow, he ordered to prepare for an attack.

Lü Bu asked Song Xian and Hou Cheng to each take 1,000 people to the left and right flanks of Cao's camp and set fire to the camp. And he led the remaining hundreds of men, ready to enter the camp from the main gate.

The plan was decided, and Lu Bu took the lead, taking the lead, and rushed towards Cao's military camp with his subordinates.

Cao Bing woke up like a dream, his face was hazy, and before he could figure out the situation, he was rushed up by Lu Bu and others and killed him directly.

Soon, the gate of Cao's camp was broken open by Lu Bu, and as soon as hundreds of people entered Cao's camp, they began to kill on a large scale, killing everyone they met.

Song Xian and Hou Cheng led people to set fire to the left and right flanks of Cao Jun, and for a while, the fire was soaring to the sky, and the ferocious fire gradually merged together under the blowing of the night wind, turning into a huge fire dragon, opening its bloody mouth, stretching out the steaming tongue of fire, and burning everything unscrupulously in the Cao army camp.

Lu Bu was even more unscrupulous in Cao's military camp, he rode a red rabbit horse, and rushed straight towards the big tent of the Chinese army, just to kill Cao Cao. And Cao Ying, who was already a sea of fire, also boosted Lu Bu's arrogance and made him more courageous.

For a time, Cao's army was in chaos, and the soldiers fled from the camp one after another, and they all fled north.

Suddenly, a short man with a short beard ran out of the big tent of the Chinese army, the man was disheveled, he didn't even have time to put on his armor, and quickly retreated north under the escort of Dian Wei.

When Lu Bu saw that man, he concluded that it was Cao Cao, so he galloped and killed the man.

Zhang Yan was three miles away from Lu Bu, and five miles away from Cao Jun's camp, but the noisy sound of fighting woke them up from their sleep, and they saw that the direction of Cao Jun's camp was blazing, and thick smoke was rising into the sky, and he couldn't figure out for the time being, whether it was Lu Bu who attacked Cao Cao and set fire to Cao's camp; Or did Cao Cao in turn surround Lü Bu in the camp and wanted to set Lü Bu on fire?

He immediately gathered his troops and horses and went to Cao's army camp to find out.

The distance of five miles is only a moment's work for a man on a horse. Zhang Yan, Tai Shici, Xu Chu and three thousand cavalry rushed towards Cao's camp non-stop.

After a while, Zhang Yan arrived at the Cao army camp, but saw that the Cao army camp was already a sea of fire, Lu Bu's army was guarding the periphery of the camp, and the Cao army was fleeing in all directions, and there were many charred corpses in the camp.

Lu Bu actually succeeded in the sneak attack!

The scene in front of him shocked Zhang Yan, he couldn't believe his eyes, Cao Cao would actually be attacked by Lu Bu, how could this be?

But the facts were in front of Zhang Yan, Cao's army fled north in a hurry, and Lü Bu led Song Xian and Hou Cheng to chase after him, leaving only 500 infantry here to kill those panicked Cao soldiers.

After Zhang Yan learned of this news, he quickly took Tai Shici, Xu Chu and 3,000 cavalry to bypass the Cao army camp, and according to the scout's report, he followed the direction of Lu Bu's pursuit and chased all the way to the north.

Lu Bu's successful sneak attack and Cao's military camp, which had turned into a sea of fire, all made Zhang Yan believe in the fact that Cao Cao was unprepared, otherwise, how could he flee in a hurry?

"Catch up, whoever obtains Cao Cao's head will be rewarded with ten thousand gold!" Zhang Yan even said an attractive reward to his subordinates, and chased after him with the army without any scruples.
