Cao Ren was furious when he saw that Li Dian's attack failed, and personally came to the bottom of the mountain to gamble. Cao's army stormed the mountain in waves, and was beaten to the ground by the stones and logs thrown from the mountain, and the time was wasted until the evening without making any progress. Cao Ren had to temporarily withdraw his troops to discuss countermeasures.

Liu Bei said: "This Beigu Mountain is easy to defend and difficult to attack, the other party insists on holding on, and it is very difficult to attack, as long as the other party throws stones and woods, we can suffer heavy casualties and make it difficult to advance!" For its consumption here, it is better to bypass Beigu Mountain! ”

Li Dian immediately agreed: "I agree." If you continue to fight like this, no matter how big or small the losses are, you don't know when you will be able to attack them. The front line has been around for a long time, but I am afraid that the reinforcements of Lu Bu's army will arrive! If reinforcements arrive, all our efforts and the price we have paid will be in vain! Cao Ren frowned and nodded, raised his head and said, "There is a valley dozens of miles to the south that can bypass Beigu Mountain and go straight to Jianye!" Which of you would like to lead an army there? ”

Li Dian was about to ask for battle, but he didn't want Liu Bei to preemptively ask for war and said: "Although you are not talented, you are willing to take on this responsibility!" ”

Cao Ren asked Liu Bei to lead 20,000 foot soldiers and 10,000 cavalry to the south, bypassing Beigu Mountain and directly inserting into Jianye.

Liu Bei received the order and immediately led his two brothers to leave the big tent.

Cao Ren frowned and asked Li Diandao, "Do you think that woman will know about the existence of that canyon?" Li Dian thought for a moment and said, "Probably not." If we hadn't happened to meet an old woodcutter in the neighborhood that day, we wouldn't have known that there was a canyon. None of the residents of this neighborhood knew that there was a canyon where it sits. Zhuge Ruoxue definitely didn't know. Take 10,000 steps back and say, even if she knows about this canyon, she will definitely not arrange defenders! ”

"Oh? Why? ”

Li Dian smiled: "First, she is a smart person, she will think that we will not know about that canyon, and second, she has insufficient troops. I think Liu Bei's raid will definitely succeed immediately! ”

Cao Ren nodded, and said with a smile: "Manchester City's words opened my mind!" ”

On this night, the moon was bright and the stars were thin, the wind was clear, the breeze caressed the treetops, and the chirping of night owls rose from the depths of the mountains from time to time.

Liu Bei's three brothers hurried along the mountain road towards the valley to the south in the light of the stars and moon. Guan Yu held the Qinglong Yanyue Knife and said to Liu Bei: "Brother, there is a cloud in the book of soldiers, 'soldiers are noble and fast', it is better for me to ride 10,000 battles through the valley to assault Jianye, what does my brother think?" ”

Liu Bei thought for a while and said approvingly: "What the second brother said is extremely true, and the second brother Lao led the war cavalry to attack first, and caught them off guard!" ”

Guan Yu was about to receive his order, and Zhang Fei shouted: "The eldest brother is not partial, and he will hand over any good things to the second brother, but let me be a cold bench, in a hurry!" Liu Bei said: "The third brother has a short temperament, but I don't dare to let you lead the army alone!" Zhang Fei immediately became anxious and shouted: "Big brother, this is too much! What does a short temper have to do with being able to lead alone? Besides, won't the second brother blow up the photos? I'll take a look! This time I'm going to be this striker no matter what! Not negotiable! ”

Liu Bei is funny and angry. Just as he was about to reprimand, Guan Yu smiled and said to Liu Bei: "If you are extraordinary, let the third brother be this forward general!" Zhang Fei was overjoyed, and said to Guan Yu with a smile: "The second brother is really good to me Lao Zhang!" But seeing that Liu Bei was still hesitating, he shouted dissatisfiedly: "The second brother has agreed, big brother, don't grind!" Didn't the second brother say that the soldiers are fast? If you grind like this, you still have the speed of a ghost! ”

Liu Bei was helpless and sighed, "That's it!" Thinking about it, Lu Bu must be unprepared, and Yide has also obtained it! ”

Zhang Fei was very angry, and as soon as he pulled his black horse, he went down to greet the cavalry. A moment later, Liu Bei Guan Yu saw Zhang Fei rushing to lead 10,000 war horsemen to overtake them and gallop forward, the rumbling sound of horses' hooves was particularly clear in the night, echoing among the mountains, startling many resident birds. Liu Bei smiled bitterly: "Look at Yide, it's just a tiger and leopard who finally got out of the cage, completely carried away!" Guan Yu smiled.

Zhang Fei led 10,000 cavalry to leave Liu Bei and them far behind, and came to the outside of the valley. The army stopped, Zhang Fei looked inside, only to see a winding mountain road erected on two saga dangerous peaks, only to see that there were old pines hanging on the cliffs, strange rocks, thorns in the valley, and so on; There was also silence above and below the mountain, and a piece of moonlight was reflected on the mountain, which shone brightly, but the valley was pitch black; The occasional call of the mountain eagle came from the valley, echoing between the peaks, making the whole valley even more lonely!

"General, do you want to send someone to step on it first?" An officer came up and asked.

Zhang Fei waved his hand, "Step on a fart!" That woman is not a fairy, can she pinch it until we come back here? The order went down, and the army immediately entered the valley, and rushed to Jianye City before dawn, and took the city in one go! The officer clenched his fists in agreement.

Ten thousand horsemen poured into the valley, cutting through the grass and thorns. Half an hour later, all 10,000 horsemen entered the valley.

Suddenly, there was a loud rumbling sound at the mouth of the valley, like thunder, and like a stormy wave. Everyone was shocked, and hurriedly reined in to look back, only to see that countless boulders had rolled down from the cliffs on both sides of the entrance, completely blocking the valley mouth. Zhang Fei frowned and shouted, "Don't panic! It's a rockfall! Hurry up and move forward! ”

As soon as the words fell, countless boulders rumbled down from the cliff in front of them, blocking the way forward. This time, everyone panicked. At this moment, countless torches suddenly lit up on the cliffs on both sides, and the shouts echoed in the valley.

The Cao army in the valley saw such a scene, no matter how stupid they were, they knew that they were in an ambush, and they were all frightened, the flags were swaying, the horses were neighing, and the sergeants were looking around in a daze, not knowing what to do.

"General, what now?" The officers asked Zhang Fei one after another. Where is Zhang Fei's way?

Clusters of fires suddenly lit up on the cliffs on both sides, and then countless fireballs rushed down from the cliffs, and the path of flames ignited everywhere they passed, which was particularly eye-catching in the night. Countless fireballs rushed into the valley, rushing the 10,000 Cao army horsemen into a scattered and thinking rush, but they couldn't escape. The fireball ignited the weeds and thick thorns under the valley, and the flames roared and spread rapidly, turning the bottom of the valley into a lake of fire in a blink of an eye.

Some people desperately attacked the mountain walls on both sides, but the mountain walls were too steep to go up, and they were smashed by the falling stones from the mountain.

Unable to flee and unable to fight, the soldiers of Cao's army could only run around trying to find a place to hide from the flames, but countless people crowded into a small waterhole under the mountain wall on the left.
