Cao Cao was reminded by Li Ru before he thought that Master Nanye had the ability to predict the future. If it weren't for Nan Ye's plan to cut down wood and build shields first, I'm afraid that the casualties of the soldiers would be several times higher. So Cao Cao went to Nanye's camp to ask for advice.

Nan Ye had been waiting for Cao Cao to come and beg him, and when he saw Cao Cao enter the account, he asked, "Meng Deke is here for the well on the mountain?" ”

Cao Cao nodded and said, "The mage expected it to be good, it was for Yuan Shao's Tushan Jing. I wonder if the mage has a plan to break it? ”

Nan Ye smiled: "I have something to break the well, but this thing is extremely secret, I don't know how Meng De can thank me?" ”

Cao Cao was not afraid that Nan Ye would ask for benefits, but he was afraid of owing Nan Ye favors, so he said: "If the mage can help me break through the well, I will capture more than one percent of the weight of the soldiers and horses and the mage?" ”

In the previous two wars, Cao Cao was divided into two percent of the materials to Nan Ye, and now another achievement is three seven open. Nan Ye's more than 1,000 people and Cao Cao's 100,000 army divided the spoils of war in 37, which was already very advantageous. Nan Ye agreed: "Meng De is happy! I have an object made by the Jiaozhou Academy of Sciences, called a trebuchet. This is the pattern, and Meng De ordered the craftsmen to follow it. With that, he took out a drawing from his bosom and gave it to Cao Cao.

Cao Cao took the drawing and looked at it, only to see that the drawing indicated the construction and operation method of the trebuchet, as well as the detailed calculation of the range, the Shiyan effect description, and so on. Cao Cao regarded the trebuchet on this drawing as a new weapon, but he didn't know that the drawing Nan Ye took out was just a drawing of a generation of catapults, and the improved version of the thunderbolt Nan Ye would not take it out to Cao Cao.

The first-generation trebuchet has the disadvantages of huge size, inconvenient operation, not easy to move, not far range, low accuracy, etc., but the advantage is that it is simple to manufacture and can be built without too many professional craftsmen. Cao Cao had hoarded a lot of wood with Nan Ye before, and rushed to build hundreds of trebuchets overnight, which were distributed within the camp wall, facing the well on the earth mountain.

The next day, there was a bang on the mountain, and Yuan Shao ordered his soldiers to release arrows in the camp. Cao Cao ordered his soldiers to pull the trebuchet together, throw the boulder into the air, and beat it up the mountain.

This generation of trebuchets had a shorter range than the improved Thunderbolt, but much longer than the bow and arrow. Countless watermelon-sized stones flew towards the well, smashing the wells on the dirt mountain one by one.

Yuan Shao's pawn had never seen a trebuchet, and was frightened by the huge boulders flying in the sky, and there was nowhere to hide. Some unlucky soldiers couldn't dodge and were directly hit by the boulder, and their brains burst out, and their bones were broken. There were also some soldiers who hid behind the well, and were not hit by the boulder, but were crushed under the collapsed well and turned into meat sauce. Suddenly there was a sound of people shouting and neighing horses on the dirt mountain, which became a purgatory on earth, and the archers were killed and injured countless times.

Cao Cao saw the scene on the mountain in the camp and couldn't help but sigh: "I didn't expect this thing to be so powerful, it is really invincible, and Master Guanghua is really a god and a man!" ”

Xun You reminded Cao Cao on the side: "The mage can create such a magical artifact, and the lord should try to prevent it." ”

Cao Cao nodded again when he heard this, and he was a little more wary of Nan Ye in his heart. Yuan Shao's soldiers were beaten by boulders, and they no longer dared to climb high to shoot arrows, and they were all forced to withdraw to the camp. These Yuan Shao soldiers did not know what a trebuchet was, so they named the trebuchet "Thunderbolt Car", describing the sound of the boulder breaking through the air like a thunderbolt.

In fact, the power and accuracy of this generation of trebuchets are not as good as Liu Ye's thunderbolts, and they are not as powerful as Cao Cao and Yuan Shao imagined. It can be said that there are very few soldiers who were killed by direct hits by boulders, and the main casualties were because of the collapse of the well, and many soldiers were killed and injured by falling. The deterrent power of the first-generation trebuchet is far greater than the actual power, and it is mainly designed to deal with the well and not the soldiers.

Yuan Shao saw that Jing Yan could not restrain Cao's army, so he ordered the generals to conspire. Xun Chen offered another strategy: "Since the Cao army has a thunderbolt to defend the camp, our army is invincible. It is better to order the soldiers to use shovels to secretly dig the tunnels and penetrate through Cao's camp, then the thunderbolt is useless. ”

All the generals under Yuan Shao's command misestimated the power of the trebuchet, and when they heard Xun Chen's plan to avoid the attack of the thunderbolt, they all said yes. So Yuan Shao used his strategy to form an engineer unit in charge of excavation, known as the "digging army", and began to dig tunnels behind the earth mountain.

Cao Jun saw that the enemy was digging a pit all day, so he came to report to Cao Cao. This time, Cao Cao learned to be obedient, and directly asked Nan Ye, Guo Jia and the strategists to discuss countermeasures together.

Nan Ye laughed again when he heard that Yuan Shao was going to play tunnel warfare, this time he didn't need any high-tech to deal with it. gave Cao Cao a plan: "This time, Yuan Shao wants to dig a tunnel and enter the camp." Meng Deke dug a trench around the camp, and Yuan Shao's soldiers dug to the edge of the camp will inevitably be exposed. You can also bury the cylinder in the ground, listen to the underground movements, and wait until Yuan Shao's soldiers are close to ambush the soldiers in the trench, and Yuan Shao's soldiers can be captured one by one, which is the method of listening. ”

Cao Cao was overjoyed when he heard the plan, and ordered people to dig trenches overnight and set up "ground listening". As soon as Yuan Shao's "digging army" dug into the trench and poked its head out, it was captured by the Cao army lying in ambush, wasting military strength in vain.

Yuan Shao and Cao Cao each made strange plans, but they could not defeat the enemy, and the two armies were stalemate. Xun You said: "Yuan Shao has a lot of food and our army has little food, if it is delayed, it will be unfavorable for our army." ”

Cao Cao didn't want to fight a protracted war, and he couldn't restrain Yuan Shao, so he asked Ji Nanye again: "Does the mage have a way to win?" ”

Nan Ye naturally knew that the turning point of the Battle of Guandu was that Xu Yu came to Cao Cao and burned the grain and grass of Wuchao. But now that the battle of Guandu is advanced, Nan Ye doesn't know when Xu Yu will surrender, let alone whether Yuan Shao's grain and grass are in Wuchao. He only knew that the key to this battle was grain and grass, so he said: "Since Yuan Shao has a lot of grain, why didn't Meng De rob his grain and grass for his own use?" ”

To say that Cao Cao is a master among the masters, but at this time, he shook his head and said: "If you don't want to, you can't listen." I don't know Yuan Shao's grain road, and I don't know where he stored grain, how can I rob the grain? ”

Nan Ye's eyes lit up when he heard Cao Cao mention the word "grain road", and what he lacked most at this time was the information about Yuan Shaotun's grain. However, as long as you find the grain road where Yuan Shao transported grain, you can find the place where Yuan Shaotun grain is located. At that time, no matter whether Yuan Shao is in Wuchao or not, Nan Ye can go to rob the grain.

With a plan in his heart, Nan Ye said to Cao Cao: "Although there are few soldiers and horses under my command, they are still elite, I might as well lead someone to investigate, if I can know where Yuan Shaotun is located, it is not too late to come back and make a plan with Meng De." ”

Cao Cao's soldiers and horses were less than Yuan Shao's, and it was impossible to storm Yuan Shao's camp, and he could only win by surprise to break Yuan Shao. At this time, the two armies were in a stalemate, and Cao Cao had no plan for a while, so he could only let Nan Ye give it a try, and said to Nan Ye: "If the mage can really find out the land of Yuan Shaotun's grain, it will be a lot of credit, but the risk of leading the troops deep behind the enemy is not small, and the mage must be careful." ”

Nan Ye got Cao Cao's military order, and when he returned to the camp, he summoned the generals, took out a map and pointed out: "Yuan Shao's army is here, if you want to transport grain, there are only these five routes, as long as we set up an ambush on these five roads, we can find Yuan Shao's grain road and find the place where his troops are stationed." What do you think? ”

Guo Jia's eyes lit up when he saw the map used by Nan Ye, and he asked, "Where did this map come from?" Why is it so accurate? If there are really only these five roads that can lead to Yuan Shao's camp, the mage's plan can be feasible. If there is any omission, I am afraid that this plan will not work. ”

The maps in Nan Ye's hands were all drawn with the two skills of positioning and memorization, and they were absolutely accurate. Not to mention the main road where grain can be transported, the mountain paths, rivers and streams are clearly marked. He nodded to Guo Jia and said: "There is nothing wrong with this map, this can be assured, but I don't know where to set up an ambush?" ”

Guo Jiadao: "Escorting grain and grass cannot be done every day, and one delivery must be enough for more than a month." One is to conceal the grain route, and the other is to save soldiers and horses. If the mage sets up an ambush in the middle of the way, he doesn't know how long it will take. Why don't you follow the road and explore the five roads? As shown in the map, these five roads lead to Yuanwu, Yangwu, Yanjin, Wuchao, and Fengqiu. If Yuan Shao is one of the five places of the army, he must set up a heavy guard, and where there are many soldiers is the place where Yuan Shao can send grain. ”

As soon as Nan Ye heard that one of the five roads was leading to the black nest, he said, "This is very good! I'll explore the black nest all the way first. If my expectations are correct, Yuan Shao's eighty percent of the grain is here. ”

Guo Jia and the others knew that Nan Ye had the ability to predict the future, and they didn't ask him how he came to this conclusion, so everyone raised troops together and walked around Yuan Shao's camp to Wuchao. If you want to talk about this thing that goes deep behind enemy lines, except for Nan Ye's ability, no one else can really do it. The first is because others don't have Nanye's map, and they can't find a path to avoid Yuan Shao's exploration of horses. The second is that other people's soldiers are not as well-trained as Nan Ye's personal guards and trapping camps.

Nan Ye was leading the soldiers and horses forward, and suddenly stopped his horse and said: "There are five thousand Yuan Shao soldiers and horses coming here in front, and the person leading the troops is the general Han Meng." ”

What Zhao Yun and the other generals admired most was Nan Ye, the enemy was still far away, and he could know how many men and horses there were and who was the leader. With such a skill, he is not afraid of the enemy's ambush at all, and even if he is behind the enemy, he can be like a fish in water, and he does not have to worry about being discovered by the enemy's probe. They didn't know that Nan Ye was scanned with skills such as positioning and star display.

Guo Jia heard that there were 5,000 soldiers and horses in front of him and said strangely: "This road does not lead to Liyang, it should not be Yuan Shao's additional troops." If you don't need 5,000 people to explore the horse, you don't need to come to the front of the black nest must be the place where Yuan Shaotun soldiers. I'll wait and ambush the side of the road to see if we can make any plans for the grain soldiers. ”

When everyone heard this, they immediately hidden, because Nan Ye's positioning skill perception distance was 794, so there was enough time for everyone to ambush. After waiting for a while, Han Meng escorted thousands of grain trucks past the road.

As soon as Xu Huang saw that it was really grain and grass, he quietly asked Nan Ye and Guo Jiadao: "Master, Fengxiao, three thousand of the five thousand soldiers are grain carriers, and there are only two thousand soldiers with complete weapons to escort them, so we can rob these grains and grass without much effort." ”

Guo Jia shook his head and said: "This place is close to the black nest, if you rob the grain here, Yuan Shao will know where the grain is stored." or exchange land to store grain, or increase troops in the nest, which is not conducive to our food robbery in the coming day. ”

Zhang Liao said unwillingly: "Wouldn't it be cheap for me to let them go like this?" ”

Guo Jia smiled: "The fat is close in front of you, how can you let it go easily?" We will follow them for the time being, and when we get close to Yuan Shao's camp, we will go out to rob and burn grain, and also kill Yuan's original sharpness. ”
