[Three Kingdoms] Burning incense and sacrificial wine

However, Cao Cao is Cao Cao after all, he quickly calmed down and made an overjoyed look:

"Wonderful! Everything depends on Ziyuan!"

Xu You was immediately refreshed by Cao Cao's enthusiasm, and the bird spirit he received from Yuan Shao was swept away.

In his joy, he sold Yuan Shao's hoarding of grain and grass without hesitation: "Yuan Benchu ​​piled most of the grain and grass in Wuchao, and eager for quick success, he sent all his troops to the front line. At this time, Wuchao is at a time when the defense is empty. As long as Meng De sends a light cavalry to attack Wuchao and burn the food and grass, within three days, Yuan's army will run out of food and will surely be defeated."

Hearing this information, Cao Cao was ecstatic, but also disgusted with Xu You.

In troubled times, it is perfectly normal to get cold feet.You can use the core military situation as a bargaining chip to surrender to the enemy. This is not only against morality, but also makes people feel uncomfortable.

He, Xu You, can bring Yuan Shao's vital military intelligence to him today, how can he know that he will not bring his own life-and-death military intelligence to serve others in the future?

Cao Cao made a decision to marginalize Xu You in an instant, not letting him touch the core military situation, and only serving him as a guest.

Xu You didn't realize it, and according to his memory, he drew the map of Wuchao and the deployment of defenses on the white silk, and gave it to Cao Cao.

Cao Cao was grateful on the face, but hated Xu You even more in his heart.

It happened that Yuan Shao was approaching Guandu and confronting Cao Cao's army.Cao Cao's army was defeated, temporarily retreated, and entered the camp to hold on.

Yuan Shao ordered people to build a high platform and set up archers to ambush Cao Ying.

Liu Ya flew into Cao Ying, and for a while, people were panicked.

Unable to resist, some generals came to ask Cao Cao if they could let Qingzhou soldiers come to help, but Cao Cao refused without hesitation.

The Qingzhou soldiers are the Qingzhou Yellow Turban Army incorporated by Cao Cao. Although they are fierce and strong, their thieves are hard to change, and they have repeatedly disobeyed military discipline.The Battle of Wancheng took the opportunity to plunder and cause chaos against his will. Cao Cao was so angry that he scattered Qingzhou soldiers and threw them to farm in various places, and then formed the Tiger Army and Tiger and Leopard Cavalry.

If Qingzhou soldiers were not greedy and unruly, and he dared not use them, the difference in strength between Cao Jun and Yuan Jun would not be so great.

But for Cao Cao, he would rather fight with the few against the many, which is extremely difficult and dangerous, and he does not want a bandit army that may turn against the enemy at any time and turn around to attack his own soldiers.

Cao Cao asked all the soldiers to retreat to the rear. Li Dian, who was in charge of logistics, was called in to appease the army first, and Cui Song was summoned to discuss important matters.

As soon as Cui Song entered, Cao Cao pulled him to sit down.

"I want to do some car throwing and destroy Yuan Shao's sentry tower. Is it feasible?"

Throwing carts... Catapults?

Cui Song made a mold for a trebuchet in a science and technology model competition in his previous life. Hearing this, he immediately made calculations on the sand with his fingers.

The trebuchet is a siege machine made using the principle of leverage. To have sufficient range and power, it is necessary to increase the power arm as much as possible and reduce the resistance arm...

Cui Song quickly carried out force analysis, and mental and written calculations at the same time. According to the materials and firmness of Yuan Shao's sentry post, he estimated the minimum impact force required when hitting the sentry post, and combined the distance between the two sides to reverse the projectile route and the stone just projected. The power when going out, and then optimize the structure of the trebuchet and modify the model.

After about a quarter of an hour, he stretched his eyebrows.

"can."

Cao Cao was overjoyed and asked someone to fetch silk and brushes.

Cui Song smoothed out the traces on the sand, drew a detailed structural diagram on the white silk, and marked the length of each component.

Cao Cao quickly took over the composition and helped dry the ink.

Cui Songdao: "Time is limited. This dump car can be built by Ma Jun, the tenth member of the Dingwu team."

Cao Cao knew about Ma Jun from his son Cao Ang, and knew that Ma Jun was very talented in fortifications, so he joined the construction of the "secret weapon".

Now that the situation is urgent, Cao Cao immediately asked people to suspend the original fortifications and invest in the construction of dumping cars.

It was completed in just three days.

Cao Cao looked at several huge catapults, and while excited, he was somewhat puzzled by the completely different structure of the catapults in the past.

"How to activate it?"

"Load the stone bombs first." Cui Song arranged for the soldiers to place the boulder they brought on the catapult's projection platform, find the strongest horse in the army, put on a horse rope about ten feet long, and tie the other end to the catapult on the launch pad of the machine.

After getting ready, he asked the soldiers who were good at riding and shooting to ride on the big horses respectively, and raised their whips one by one.

I only heard the loud noises of "rumbling" one after another, and with the thunderous firing sound, huge stones flew high and high, and flew towards Yuan Shao's sentry tower and earth barrier along a strangely precise arc.

Not only Yuan Jun on the opposite side was startled by the loud noise, he lay on the edge of the sentry tower and the earth barrier, staring in horror at the black unknown object approaching from far.

The people on the other side were also startled by the massive rock throwing, all of them were stunned and opened their mouths wide to look at the spectacular scene in the sky.

Boom-boom-boom-boom-boom-

Every single boulder fell on Yuan Jun's sentry towers and earth barriers, blasting Yuan Jun's hastily built strategic terrain to pieces.

Yuan Jun ate a mouthful of ashes, and all the archers guarding the sentry were affected, and suffered injuries of varying severity, both shocked and terrified.

A surviving soldier said: "What was that just now! I clearly heard thunder!"

Another soldier said: "I heard that when Cao Jun attacked Xuzhou, they used immortal methods several times. Could it be that they—"

Before he could finish speaking, his head was cut off by a sharp knife behind him.

Blood sprayed on the faces of several people nearby, and it was so hot that they shivered.

Zhang Xi retracted his saber, looked around coldly, and said loudly:

"This is a catapult (catapult). Who has never seen it when they attacked the city? As for the fuss?"

Probably because Zhang He's contemptuous expression was too obvious, the soldiers calmed down and were no longer uneasy.

Zhang Yun continued, "If Cao Cao's side really has a fairy method, it would have been used long ago, why wait until now?"

He waited for everyone to digest his words, and then said, "It's just a bluff. Cao's army has people who are good at siege equipment, and our army also has people. Why panic?"

Three rhetorical questions were thrown out, and everyone's minds gradually settled.

Seeing the solid morale of the army, Zhang He smiled grimly and raised the long knife in his hand,

"Whoever dares to talk about ghosts and gods and disturb the morale of the army, I will chop off his head and use it as a stepping stone for the stove!"

All the soldiers felt chills at the same time, not daring to mention the words of gods and ghosts.

Zhang Xi ordered a few light cavalry and the archers and crossbowmen who survived the rotation, and got off the high platform.

"The throwing car needs to be loaded with stone bombs, there must be a gap, all the soldiers will rush with me! Go and destroy all the bomb platforms on the throwing car!"

"promise!"

When he was still more than half away from Cao Jun, Zhang Yun shouted: "The riders cover! The archers are ready! Twenty feet away, shoot me!"

Unexpectedly, just as he finished yelling this sentence, strange pieces of wood suddenly appeared on the edge of the shield lined up on Cao Jun's side.

Zhang He's eyes were sharp, and he could see at a glance that the strange wood was a crossbow, and the color changed drastically.

"not good!"

Before he had time to warn the soldiers, the sound of breaking through the air sounded.

More than a dozen unprepared cavalrymen were shot and killed on the spot. Zhang He rode his horse back and ordered in a hissing voice, "Withdraw! Quickly withdraw!"

At this time, he has not yet entered the range of the archer, and there are no barriers around him. If he insists on rushing over, it is tantamount to courting death.

Zhang He was sweating coldly while leading the army to retreat: How is this possible!The shooting range of ordinary Han crossbows is far inferior to the special bows and arrows of elite soldiers.Even if Cao Jun could manufacture a powerful crossbow with an extremely long range, he would not be able to find so many warriors who could resist the recoil of the powerful crossbow.How could Cao Jun's bows and crossbows be shot in front of his eyes like a rain of arrows before his elite soldiers stepped into the range!

How could Cao Jun have such a sharp weapon!

Thinking of the catapult not long ago, Zhang Xi felt heavy, and led the Qingqi who had lost more than half to the back of the earth barrier, avoiding the battle.

He ordered the soldiers to stick to their positions, and sent his own soldiers to lead Yuxi to the rear to tell Yuan Shao the situation on the front line.

Yuan Shao frowned severely when he received the letter.

He paid great attention to Cao Cao, so he naturally knew the rumors about Cao Cao's attack on Lu Bu.

He is sure that the so-called "God's Punishment" is just some unexplored method. After several months of research, although he can't understand its meaning, he can prevent it from the root.

No matter what kind of weird method it is, it's just an opportunistic way, and it won't work the second time.

Because of taking precautions in advance, Yuan Shao didn't feel any fear of Cao Cao's methods.But he never expected that just when he thought he was sure of winning, Cao Cao came up with something new, which dealt a severe blow to the morale ahead.

Yuan Shao was annoyed for a while, reopened the Yuxi, and reread it carefully.

Combined with Zhang Yun's description and guess, Yuan Shao also believed that the catapult that knocked down the sentry tower... But who's catapult sounded like thunder and could project so far?

He specially arranged for the archers to conduct disorderly shooting in order to prevent Cao Jun from using siege equipment to destroy the strategic high ground.But Cao Jun was able to use a trebuchet to blow down the sentry tower from such a long range! ?With the strength of the siege equipment, wouldn't it be easy to siege the city?

There is also the crossbow with a range farther than the special bows and arrows made by elite soldiers, but which weakens the recoil. If Cao Jun equips this thing on a large scale, wouldn't it be equivalent to gaining several top archers for nothing?

Yuan Shao was so annoyed that he walked back and forth for more than ten steps, and finally gave the order: "Transfer the ordnance to the front."

Cao Cao has improved ordnance on his side, and Yuan Shao may not have one.

It's just relying on the number of soldiers and the strength of the generals, and they don't want to spend it.

After Yuan Shao gave the order, he sat in the tent and pressed his temples with a headache.

It didn't take long before he got the news that the ordnance was put into use and Cao Jun retreated temporarily.

Yuan Shao looked up to the sky and laughed loudly, ate half a bowl of rice extra, got into bed early at night, and slept soundly.

However, this good sleep did not last until dawn.

In the middle of the night, some soldiers rushed outside Yuan Shao's tent to wake him up and convey the urgent military situation.

"Report to my lord! General Chunyu sent an urgent message! Wuchao was attacked by Cao Cao!"

Yuan Shao suddenly stood up and shouted in disbelief:

"Say it again!"

"A letter from General Chunyu! Wuchao was attacked by Cao Cao!"

Yuan Shao got up in a hurry and kicked the chamber pot over.He didn't have time to straighten his clothes, so he just put on a coat casually, and summoned all his advisors to enter his camp.
