Cao Cao and Yuan Shao saw each other in front of the battle, which can be described as very red-eyed. Xu Chu and the others will hug Cao Cao in front of the horse formation. Cao Cao pointed at Yuan Shao with a horsewhip and said: "The fourth generation and three princes of the Yuan family, the ancestors are all loyal to Hanlu. Now that he has made a mess and proclaimed himself emperor, is he worthy of his ancestors? ”

Yuan Shao said: "The world is the world of all people, the virtuous live in it, and the virtuous lose it." The Han Emperor has no virtue and is not enough to keep the community, so Zen let Yuan Highway, and Zen let me, with the jade seal as evidence, how can he claim to be the emperor in vain? Your name is Han Xiang, but you are really a thief! Hijacking the first emperor, the crime is full of crime, even worse than Dong Zhuo and Li Dao, and dare to slander me for rebellion? ”

Cao Cao said: "Today I am begging you by the edict of the Son of Heaven of the Han Dynasty!" ”

Yuan Shao said: "I beg the thief to save the first emperor with my clothes!" ”

When Cao Cao heard that Yuan Shao also knew the edict, he immediately thought that Liu Bei had voted for Yuan Shao, and he was furious at that time and ordered Xu Chu to fight with horses. Yuan Shao had already made up his mind not to fight with Cao Cao, so he ordered Gao Ran to lead 10,000 strong crossbowmen to advance into the front step by step, followed by 10,000 strong archers.

Xu Chu is nicknamed the tiger idiot, but people are not stupid, and they know that no matter how powerful they are, they can't resist the salvo of ten thousand crossbows, so they can only retreat. Cao Cao ordered the Xiahou brothers to lead 5,000 sword and shield soldiers to break Yuan Shao's crossbow array, but Gao Ran ordered the archers to shoot on their backs. For a time, ten thousand arrows were fired at once, and arrows rained down.

Xiahou Xuan and Xiahou Yuan hurriedly ordered their soldiers to use shields to block the rain of arrows falling from the sky, and at this time, Gao Ran gave another order, and the 10,000 strong crossbowmen in the front row pulled the crossbow machine, and the crossbow arrows shot out flat. The rain of arrows on his head was still unstoppable, and the crossbow bolts in front of him arrived again, how could Cao Jun resist? For a time, there were countless arrows, and Yuan Shao took the opportunity to drive his troops to cover up, and Cao's army was defeated.

It's okay for Nanye's more than 1,000 elites to follow Cao Cao to fight a tailwind battle, but it's really unrealistic to turn the tide and help Cao Cao turn defeat over Yuan Shao's hundreds of thousands of troops. Unless Nan Ye let out more than 1,000 people and go straight to Yuan Shao's main formation to behead him. But how could Nan Ye be willing to let his cronies work hard for Cao Cao? He's not that stupid. So he was defeated and retreated with Cao's army, and only went down to Guandu to go to the village.

Cao Cao's defeat was a night back to before the liberation, and the territory captured by Yan Liang and Zhu Wenchou before was returned to Yuan Shao. If it weren't for Cao Cao's Guandu camp, which was as strong as a walled city, I am afraid it would have been taken away by Yuan Shao in one fell swoop. Now Cao Cao can only stay in the camp to avoid the edge for the time being.

Yuan Shao's army approached Guandu Xiazhai and attacked Cao Cao's camp several times, but was held by Cao Cao. Cao Cao's camp is surrounded by giant trees like a city wall, and the wooden fence is equipped with antlers and thistles. Yuan Shao's cavalry could not rush in, and bows and arrows could not be shot in, if the infantry was advanced, Cao Cao's pennies guarded the village and shot arrows outward to kill and injure Yuan Shao's men and horses.

After several failed attacks, Yuan Shao gathered the generals to discuss countermeasures: "Now Cao Cao's defense of the camp is like defending the city, although our army is numerous, it is difficult to capture it for a while, do you Aiqing have a good plan?" ”

Guo Tu said: "Why don't you use the method of rushing cars and ladders to break the camp?" ”

Feng Ji said: "Rushing cars and ladders are all ways to break the city, Cao Ying has no city gate to rush, and no city wall for soldiers to climb and gain a foothold, so what can be done with the erection of cloud ladders?" In my opinion, a dirt hill can be built in front of Cao Cao's village, and a building turret is set up on the soil mountain, so that the sergeant can stand on the turret and release arrows into the village. If Cao abandons the village and goes, Bixia will get this pass, and Xuchang can be broken. ”

Yuan Shao knew that the Loulu mentioned by Feng Ji was also called a Lou Che or a well, and it was also a siege weapon. Its main body is a very high wooden frame, with a watchtower on it to hide soldiers, a wheel axle to move underneath, and soldiers can be higher than the city wall in the watchtower, and shoot arrows into the city from a high position. If, according to Feng Ji, the earth mountain is built first and then the well is set up, then the arrows can be shot into the Cao army's camp from a long distance, and the Cao army will not be able to fight back.

Everyone heard that Feng Ji's words were a good plan, and Yuan Shao was also overjoyed, so he selected strong soldiers in the army to pick up soil to the side of Cao Cao's village to build a mountain.

Although Cao Cao saw Yuan Shao's soldiers piling up earth mountains in the camp, he also knew that Yuan Shao was not at ease, and ordered people to lead the troops to rush out several times, wanting to destroy Yuan Shao's project, but Yuan Shao shot back with a crossbowman.

Others may not know Yuan Shao's intentions, but Nan Ye knows it. He didn't bother to stop Yuan Shao from building the mountain, but let his men and horses go out of the back camp to cut wood everywhere and transport it back to the camp.

Cao Cao heard that Nan Ye was collecting wood from everywhere, so he came to Nan Ye's camp and asked, "The mage ordered people to cut wood, but he wanted to prevent Yuan Shao from building a mountain?" ”

Nan Ye nodded and said, "That's right!" ”

Cao Cao was surprised: "In this way, the mage already knows what Yuan Shao's intentions are? ”

Nan Ye said with a smile: "What's so difficult about this, Yuan Shao wants to condescendingly shoot arrows in the city." I want to order people to build wooden houses in the village, and to build more wooden shields to avoid them. Not only can you prevent arrows, but you can also get Yuan Shao's arrows for your own use, why not? ”

Cao Cao said suddenly: "If it is not what the master said, I still don't know Yuan Shao's intentions, and now I can let the whole army use the strategy of the mage." With that, he ordered the sergeants in the battalion to also go to the cutting of trees and make shields.

After Cao Cao left, Guo Jia asked, "Why didn't the mage tell Meng De earlier that there was a thunderbolt car that could break through the well?" ”

Nan Ye smiled and said, "If I said it in advance, how could Meng De come to ask me for advice?" How can I claim benefits from Mende? ”

Guo Jia couldn't help but smile and said, "The mage is so shrewd, if he doesn't bring me with him this time, he won't suffer." ”

Cao Cao and Nan Ye were cutting wood in the camp to prepare, and Yuan Shao kept picking up earth and mountains outside the camp. Ten days later, Yuan Shao built more than 50 earth mountains, and sent crossbowmen to stand on them and shoot arrows into Cao's camp.

Nan Ye prepared early, and there were few people under his command, so he had replaced the tent with a wooden house, and let Yuan Shao shoot arrows on the mountain, Nan Ye was not afraid at all. On the other hand, Cao Cao's soldiers were not so lucky, the wooden houses of the 100,000 army could not be built in ten days, so only a small number of wooden houses were built for the generals to hide. The rest of the soldiers were to defend themselves against the arrows with wooden shields.

Yuan Shao saw Cao Jun walking on the ground with shields on the camp, like turtles, and couldn't help but hahadaxiao. Seeing this, the soldiers also shouted and laughed, and rewarded Cao Jun with a rain of arrows when they had nothing to do, jokingly calling Cao Jun "the eighth king in the rain".

Cao Cao was reminded by Nan Ye to make preparations, so Yuan Shao's move of ten thousand arrows caused few casualties to Cao Jun. However, after being beaten and scolded by Yuan Shao's soldiers for several days, Cao's morale dropped a lot, but he was also suppressed by Yuan Shao remotely and could not fight back. So Cao Cao summoned the generals and asked, "Do the princes have a plan to break Yuan Shao's soil and wells?" ”

Xun Yu, Xun You and other strategists are not low in intelligence, but none of them are proficient in civil engineering, and Liu Ye, who was supposed to give advice to Cao Cao, has already been poached by Nan Ye, so everyone is at a loss. Suddenly, Li Ru spoke: "Since the Guanghua National Master has foresight, he expected Yuan Shao's strategy, maybe there is a way to deal with it. Why didn't the prime minister ask the national teacher for advice? ”
