There used to be a very dazzling term in modern society, called: butterfly effect.

In more scientific terms, it means that in a dynamical system, small changes in the initial conditions can lead to a long-term huge chain reaction of the whole system.

In the words of the common people, the world is unpredictable, and the world is really wonderful.

The world is indeed a wonderful thing, no one can tell what will happen to it in the next second, just like the current Yuan Shang, although he is alone and his strength is limited, but under the instigation of his little butterfly wings, the details of the battle of Guandu have changed little by little.

It's like Yuan Shao sent Zhang Jaw and Gao Ran as the vanguard to fully support the Black Nest, which is completely different from the situation in history.

In history, Yuan Shao sent Zhang Jaw and Gao Ran to storm Cao Cao's camp, and sent Jiang Qi to send troops to reinforce Wuchao.

You can't have both fish and bear's paws, and Yuan Shao ended up with a tragic end of losing his wife and soldiers.

But now the situation is different, after Yuan Shao learned that Yuan Shang was in danger of the black nest, the heart of protecting the calf was born spontaneously, and he shook off the decadent appearance of hesitation and tossing on weekdays, and changed into an immediate order: go all out to reinforce the black nest! The glorious image of the wise and martial arts that the big tree does not have in his daily life brought it back to Guo Tu.

Yuan Shao may be an incompetent monarch with faults, but it is undeniable that he is definitely a good father who is responsible for his son.

The words are divided into two ends, not to mention that Yuan Shao sent troops to reinforce Wuchao, and the other is to say Zhang Liao, Xu Chu is comforted by Cao Cao, and the two generals lead the tiger and leopard to ride back from the front and rush towards the rear army led by Cao Cao.

After probably less than twenty miles, the second general finally made peace with Cao's rear division, and the strange thing is that Cao's rear division was not ambushed by Yuan's army, but was smoothly advancing towards Wuchao.

The generals who commanded the infantry of the rear army were Cao Wei's other two famous generals, Xu Huang and Yu Ban.

Xu Huang's appearance is quite good, with three long beards, majestic and majestic, sitting on a good horse, with a big axe in his hand, leading the rear army to take the lead, quite a bit of heroic momentum.

Seeing Zhang Liao and Xu Chu leading the army to rush back, Xu Huang couldn't help but be a little surprised, looking at them didn't look like they had gone through a fierce battle, why didn't they rush back after a moment's effort?

Riding a few steps forward, Xu Huang followed Zhang, Xu Erjun, a slight salute, and said strangely: "The two generals were ordered to be the vanguard of the front, but now they are leading the army back, I don't know why?" ”

Xu Chu clenched the tiger-headed war knife, and whispered to Xu Huang with cracked teeth: "General Xu, has he ever had anything to do?" ”

Xu Huang was curious when he heard this, and he couldn't understand what this tiger idiot was talking about, so he said strangely: "What does General Xu mean by this?" Don't know why? ”

"Pretend to be confused! Ask if your lord is hurt! ”

Xu Huang suddenly smiled dumbly and said, "Lord Sikong is all right, and there is nothing wrong with him." ”

Zhang Liaoti stepped forward immediately, took a careful look back and forth, and said, "Gongming, has your rear army ever been ambushed by Yuan's army?" ”

Xu Huang shook his head when he heard this, and said, "I waited all the way to this point, and I didn't meet half of the Yuan soldiers, why did Wen Yuan say this?" ”

Zhang Liao let out a long sigh and was about to explain, when he suddenly heard the sound of horses' hooves behind Xu Huang, but it was a gray horse slowly walking in front of several people.

On the gray horse, I saw a rickety middle-aged man looking at Zhang Liao and Xu Chu with blazing eyes.

He is short in stature, his appearance is not outstanding, a face that is like being increasingly baked by the sun is covered with pieces of cangskin, his hair is half black and half white, slightly sparse, loose comb, and he has a bun on the top of his head, the years have left a deep and cruel trace on his face, and many years of conquest and governance are also regarded as his hard work, at this moment he looks like a very ordinary middle-aged man, without any brilliance and outstanding.

But looking at the world, no one dares to underestimate this seemingly ordinary middle-aged man.

Sweep the yellow scarf, ask Dong Zhuo, chase Liu Bei, except Yuan Shu, destroy Lu Bu, welcome the Son of Heaven, make the princes, most of the heroes in the world are defeated in his hands, rolling the Yangtze River, the big waves sweep the sand, in today's world, except for him, who is qualified to call himself a hero?

He is eloquent and meritocratous, but at the same time, he is murderous and suspicious by nature, just to ensure the glorious continuation of his Cao family!

Having fought for half a lifetime, killing half a lifetime, he has done a lot of right things and done a lot of wrong things, and the battlefield of great achievements and bones has illuminated his life with glory.

Merits and demerits are only narrated by posterity, and many things in ancient and modern times are all laughed at, and he doesn't care what posterity says about him.

He is none other than Cao Cao, Cao Mengde.

Almost instantaneously, I saw Zhang Liao and Xu Chu hurriedly turn over and dismount and bow to Cao Cao on one knee.

"The last general Zhang Liao ....."

"The last general Xu Chu!"

"See the lord!"

"Wenyuan, Zhongkang." Cao Cao slowly opened his mouth, his voice hoarse like a decaying dead wood: "Alone with the two of you as the pioneer to take the black nest, why are you waiting here?" ”

Zhang Liao and Xu Chu glanced at each other, Xu Chu scratched his head, he didn't know how to answer, or Zhang Liao brushed his thoughts, and replied respectfully: "Back to the lord, the two of us went and returned, but I really care about the lord's safety, and I have to do it, and I hope the lord will forgive me for my mistakes?" ”

"Oh?" Cao Cao raised his eyebrows when he heard this, obviously a little curious about Zhang Liao's statement: "Lonely's safety? What about that? ”

Zhang Liao's words were concise and to the point, how Shicai and Xu Chu rushed to the black nest, how the black nest caught fire, how there were ambushes on both sides of the mountain li, and how did a young general who did not know his name be...... Trick them..... And so on, choose the key points, and report them to Cao Cao simply and quickly.

After Cao Cao listened, he was silent, touched the beard on his chin, and only thought for a moment, then smiled.

"Order, the whole army immediately advances, hurry to the black nest, do not delay."

Xu Chu hurriedly said: "Lord, the land of the black nest has caught fire, and I am only afraid that there will be no food, Xu Yu deceived me into coming here, the meaning is unknown, and the lord needs to retreat quickly." ”

Cao Cao shook his head and said with a smile: "Xu Yu came to vote, it is not clear whether it is really deceitful and lonely, but it is certain that there must be food in this black nest!" Don't be suspicious, go with the lonely quickly. ”

*******************

The mountain girl outside the camp of the black nest.

"Third son, something is wrong!" Guo Yuan hurriedly ran to Yuan Shang's side, and said in a low voice: "The dust on the road is due to the south again, and the sand is all over the sky, I think there are soldiers and horses coming, but I am afraid that Cao Jun will go and return!" ”

Yuan Shang sat on the stone of Shanli, and his eyelids jumped when he heard this.

"Alas——, just a lot of effort, Cao Jun actually came back again, who is in a hurry to go to the grave...... Guo Yuan, on the side of General Chunyu, how is the grain and grass transported? ”

Guo Yuan couldn't help but smile bitterly when he heard this: "Hundreds of thousands of people's grain and grass, how can it be said that it can be transported after it is finished?" Those who moved into the mountains and forests are only afraid of only two or three out of ten. ”

Yuan Shangchang sighed: "Okay, it's already very good to be able to move out of these, send someone to tell General Chunyu that there is no need to move, quickly gather the generals and ambush them in the camp in front of the black nest, let him be clever and rush out at the right time!" ”

"Look for the timing..... Rush out .... Kill Cao Jun? Guo Yuan didn't understand too much.

Yuan Shang shook his head: "Kill a fart, let him see the right time and come out to save us." ”

Guo Yuan was immediately deflated when he heard this, and he was really negative under this order.

When I was young, I saw Cao Jun going and coming, there seemed to be a lot more soldiers and horses than just now, and the two generals Zhang Liao and Xu Chu were still among them, not only that, but also a few more generals.

Looking at the firelight of the black nest, Yuan Shang felt bitter in his heart, these generals of the Cao army are not good at looking at their appearance, in contrast, although the Yuan army has many soldiers and horses, it is really inferior in terms of talents.

Seeing that Cao's army had arrived, Yuan Shang ordered Guo Yuan behind him: "Order the soldiers hiding on the mountain to wave their flags and shout, fiddle with smoke and dust, and continue to bluff....... Why do I say continue? ”

Guo Yuan arched his hand listlessly and said, "Promise....."

Since joining the army, Guo Yuanzhen has never seen a war so weird, whining and chirping, thundering and not raining, sneaking like a thief, what kind of battle is this?

On the secluded mountain, the pole and pole banner were erected again, the smoke and dust rose in the darkness, the gongs and drums shook the sky, and the shouts of killing resounded.

Rao is Zhang Liao's battle-hardened face, and his face can't help but be red.....

Here it is again, the same as just now.....

Yuan Shang was dressed in white armor, and once again appeared majestically on top of the mountain, staring at Zhang Liao and Xu Chu under the mountain, and shouted loudly: "Those two thieves are so faceless and skinless, this general is soft-hearted and has already let you live, I don't know how to send you to death again!" Are you tired of hanging yourself? ”

Zhang Liao: ".........."

No matter how reckless and ignorant Xu Chu was, he could also see that Yuan Jun was in the suspicious array at all, and when he saw that the white-armored young general was still standing there, his mouth was not dry, and suddenly a nameless fire surged, and he hugged his fists and said: "Lord, Xu Chu please fight!" ”

Cao Cao smiled and waved his hand slightly, looked up at Yuan Shang on the mountain, and said loudly: "The young general on the mountain, I don't know if you can report your name?" ”

Yuan Shang turned his head and looked at Cao Cao, who was speaking.

The eyes of the two pairs collided with each other, and for some reason, the two of them felt their eyelids jump for no reason.

It's strange, how can it be like a heart with a soul, and it's still beating with the right eyelid?

Yuan Shang froze and shouted at the bottom of the mountain: "How can this veteran not understand the rules? Before asking someone's name, shouldn't you report your name first? ”

Cao Cao smiled faintly when he heard this, and naturally showed a domineering aura in his smile, and replied: "Xiaoyou is right, but this matter is the old man Meng Lang, Xiaoyou listen, the old man's surname is Cao, a single name, a single name, the word Mengde, I don't know if Xiaoyou has ever heard of the old man's name?" ”
