The Legend of Yuan Yao in the Three Kingdoms

For Yuan Yao, the situation on the battlefield changed suddenly.

Yuan Yao could see it in the field battle. With Cao's army splitting up and attacking from all sides, he was too weak to resist.

It is really difficult to have a chance to win against Cao Cao in the wild.

Now trapped in a small county, it is impossible to get out, so how can we talk about rushing to help Wancheng?

Now Yuan Yao is also caught in a dilemma.

If you leave this place, then Wancheng will be destroyed by Cao Cao.However, if you don't retreat, this small county can't hold on for too long.

It was Cao Cao who put all his eggs in one basket. He recognized Wancheng and dared not send troops again. If he tried his best to deal with him, he would be even more dangerous.

Yuan Yao couldn't think of anything, and Cao Cao found a loophole when he tried to fight, and even thought of a way to break the enemy.

Secretly sighed in his heart, Yuan Yao, who had been killing for a whole day and night, couldn't rest at night, and in a relatively good house in the county town, Yuan Yao was still discussing countermeasures with Pang Tong.

"Shi Yuan, now that Cao Jun has made this method of ambush from ten sides, if he goes out of the city to fight again, I'm afraid it will be difficult to defeat."

"However, if you don't leave the city, you won't be able to connect with Wancheng. It's pointless to stick to this county, but it's easy to put yourself in a disadvantageous situation."

At the end of Yuan Yao's speech, he also expressed his intention to retreat.

Pang Tong understood what he heard, and shook his head repeatedly after a little thought: "If the young master leaves at this time, Cao Cao will have no worries, and Wancheng will be destroyed by him. After he occupies Wancheng, it will cost thousands of dollars to plan any plans in the future." Double the power."

"Compared to this, the hardship at this time is nothing to worry about, but it's just a little bit of trouble."

These counselors have a way of persuading people, and Pang Tong's words directly suppressed Yuan Yao's desire to evacuate.

Pang Tong said again: "As for Cao Cao's siege here, he is more anxious than our army. Why should you be in a hurry to withdraw?"

Yuan Yao nodded again and again, and settled down in his heart, no longer thinking about evacuation easily.

During the next three days, Cao Cao was really eager to attack Yuan Yao.

However, relying on the city defense of the county, coupled with the desperate battle between Xu Huang and Zhou Tai, Cao Cao couldn't help Yuan Yao for a while.

But Yuan Yao also defended very hard.

In particular, the enemy generals went into battle in turn, greatly consuming Zhou Tai and Xu Huang's strength. Two times in a row, Yuan Yao led Sun Yu to personally supervise the battle, and they barely defended.

I'm afraid it will be difficult if we live a few more days!

...

During the three days, Yuan Yao didn't stop thinking about it, but unfortunately he still couldn't find the right way after thinking about it. At the end, he was also a little discouraged.

"In the final analysis, I am not much smarter than the ancients. Especially when facing Cao Cao's advisers, I am afraid that I am not as good as that."

"It's really comparable, but it's just relying on the accumulation of thousands of years to bully and bully Pang Tong. On the battlefield, you can't use mathematics and physics to break the enemy's formation!"

"Trigonometric functions, electricity and heat, those are useless!"

Ah... wait!

Thermal?

Yuan Yao suddenly felt a flash of inspiration, and an idea suddenly jumped into his mind.

Now I am separated from Wancheng by a hundred miles, which sounds like a lot, but it is only about forty kilometers in contemporary times.

Whether it is near or not, whether it is far or not.

If one relied on the strength of human feet, one would naturally have to run for some time on this rough road.At least, it will take a day or two.

Coupled with the fact that everything is under the control of Cao Jun now, it is really difficult for people to report to Wancheng by walking on land.

It’s just that instead of walking, we can rely on flying!

According to Archimedes' principle, when an object has the same volume as air, but its weight (density) is smaller than that of air, it can fly, which is the same as the buoyancy of water.

When the air in the ball is heated, a part of the air inside the ball will flow out from the ball due to the expansion of the air, making the inner air density smaller than the outer air, so the ball filled with hot air will fly.

This is the basic principle of a hot air balloon.

However, hot air balloons cannot be made without knowing this one, and the fields involved are quite complicated.

Not to mention anything else, just say that without modern chemical industry, it is impossible to produce high-strength and flame-retardant materials.If you want to carry people, it is a dream!

It's just that we can't make hot air balloons, we can make Kongming lanterns, no, it should be said that we can make Yuanyao lanterns!

In contrast, Kongming lanterns are much simpler to make.

Make a square frame with bamboo strips, paste it with paper, and make a headlamp. Burning turpentine is placed on the chassis, and the lamp can fly into the sky with hot air.

Although you can't take people away, as long as you can spread the news.

I believe that Jia Xu, who is waiting in Wancheng, will be able to feel it when he sees a vision from the sky!

If this method can't make Wancheng send troops, I'm afraid this embroidery really can't save it.

No matter what, always do the last fight!

Yuan Yao called Zhou Tai immediately, and explained it carefully.

That day, the entire county town was ransacked by Yuan Yao, and he ordered people to make Kongming lanterns according to his instructions overnight.

And at dusk, Zhou Tai left the county with the last hope of this battle with [-] sergeants, and headed straight for the high slope nearby.

Chapter 282 The brightest star in the night sky

Wancheng.

Zhang Xiu in the city has been waiting for Cao Jun to attack, but there is no movement.

Strange in my heart, I also asked scouts to inquire, but the news I got was that Cao Jun was camping not far away.

It seems that there is a lot of construction and manufacturing of siege equipment.

Make the whole camp full of dust and smoke, so that people can't see clearly.

However, although it is not true, just looking at the momentum is too difficult to create. It is obvious that the army is ahead, so Zhang Ji dare not act rashly.

It's just that the days of waiting only make people anxious, and Zhang Xiu couldn't bear to ask Jia Xu: "Wen He didn't say that Cao Jun must fight quickly, why is he so dawdling outside the city now, and he is not in a hurry at all."

Jia Xu said in a buzzing voice: "I think it's probably because Yuan Yao from Jingzhou has arrived and kept Cao Mengde out, so he couldn't attack the city."

Zhang Xiu heard that Jia Wenhe was so calm and calm, but he was really shocked.

What?

Yuan Yao from Jingzhou is here, so why didn't you say it earlier!I also like to cooperate with the inside and outside, and attack Cao Cao!

It's just that my uncle entrusted this important task to me, and Zhang Xiu has grown a lot now, knowing that Jia Xu may have other concerns, he quickly asked: "Since this Yuan Yao has arrived, why don't I take advantage of this opportunity?" , send troops to Wancheng, and encircle Yuan Yaolai?"

Jia Xu listened to Zhang Xiu's inquiry, and instead of leading the troops out in a hurry, he showed a somewhat satisfied expression, and then responded: "If Yuan Yao really came, I will let the general attack Cao's army. But is it really the case? , I’m not sure, so I can only say more or less.”

"Then Cao Cao is good at using the art of war and is proficient in the way of falsehood and reality. It is also possible that he did this intentionally. In fact, he wanted to lure the snake out of the hole and lure the general out of the city."

"How can I get the general to send troops without being sure?"

After hearing Jia Xu's words, Zhang Xiu finally understood, and despite the admiration in his heart, his sorrow did not diminish at all.

He said rather worriedly: "I don't know what Cao Cao will do, it just makes people worry."

But Jia Xu said: "Just wait and see the changes, since there will be changes."

Zhang Xiu sighed all the time, and had no choice but to wait in peace.

Fortunately, Yuan Yao didn't make him wait too long.

"General! Get ready soon, let's dispatch troops!"

It was night, Zhang Xiu had patrolled the city wall and planned to take a rest, before he took off his armor, he saw Jia Xu hurried into the house with an excited expression on his face.

To be honest, when Zhang Xiu saw Jia Xu's expression, he didn't pay attention to what Jia Xu said.

The clouds have always been calm and the breeze, when did you see this moment when Jia Xu was in such high spirits?

It took a long time to realize that Jia Xu was going to send troops by himself!

Immediately said: "But the letter from Jingzhou?"

But Jia Xu's eyes that were neither sad nor happy, now have a little light, although it is not very obvious, but it is really rare for a person who is over fifty years old.

Pulling himself straight, he said: "There is a letter, and this letter has to be seen by the general himself."

Zhang Xiu nodded when he heard this, and he wanted to take a look at the letter that came here.

It's just that Jia Xu didn't seem to be bringing a messenger, and he didn't hold a letter in his hand. Just when he was a little confused, Jia Xu pulled him out of the mansion.

Then he pointed to the distant sky and shouted: "Look, general, the letter is in the sky!"

Zhang Xiu was a little dazed.

What letters in the sky?

How can this still go to heaven?

I didn't have time to think about it, I just followed Jia Xu's words and looked up to the sky.

At first glance, he was slightly dazed.

There seem to be so many stars in the sky tonight!

Looking carefully again, I saw that the distant starlight was erratic, fluttering at will with the night breeze.

Only then did Zhang Xiu see that this is not starlight, it is clearly lights all over the sky.

Yuan Yao made this up?

How could he put the lamp in the sky?

There was a question in my heart that couldn't be answered, but I heard Jia Xu say from the side: "These visions must have been created by Yuan Yao, presumably that Yuan Yao was fighting with Cao Jun and couldn't move the envoy here, so he used it." to remind us of this method.”

"General, please prepare quickly and dispatch troops as soon as possible to defeat Cao's army with Yuan Yao."

Hearing Jia Xu's words with such certainty, Zhang Xiu couldn't hesitate any longer, no matter it was day or night, he went straight to the military camp, prepared to summon the generals, and agreed to go out tomorrow.

It's just that when I came out of the mansion, I saw the soldiers and civilians in Wancheng looking up at the sky in the distance.

Apparently it was also because of hearing about such unheard-of visions and not wanting to miss them.

Zhang Xiu looked back subconsciously, but saw that Jia Wenhe was also holding his hands behind his back, staring at the lights all over the sky in a daze.

I don't know what I'm thinking about.

Zhang Xiu and Jia Xu in Wancheng have seen such a scene, and Cao Jun in front of Yuan Yao can see it all at a glance.

It's just that no matter how capable Cao Cao and Guo Jia are, they can't fly to the sky and shoot down the lights that have risen to high altitudes.

However, in the camp at this time, Cao Cao was neither sad nor happy, his face was calm, and he was not angry at all when he was spoiled by a major event, but he just said to Guo Jia who was beside him: "Feng Xiao, it seems that you don't care. Whether it's Wancheng or Yuan Yao, we can't take it down."

Guo Jia looked at his camp, which was already brightly illuminated by the rising lights, and with the light shining in his eyes, he dared to sigh: "There are so many lights, it can be seen compared to Wancheng. Zhang Xiu must have I feel that I am afraid that I am already thinking about going out at this moment."

"Thousands of yellow scarves outside Wancheng must not be opponents, I am afraid they will collapse at the first touch."

After a pause, he said helplessly, "Mr. Cao, we have to go back to Yanzhou."

Cao Cao was not surprised to hear that.

Yuan Yao's tossing, Wancheng is very likely to understand its meaning.At that time, when the Xiliang iron cavalry in Wancheng set out to march, how could the yellow scarves of those ten thousand people be able to stop them.If you are attacked from both sides, you will definitely lose!

Naturally, this risk cannot be taken.

What's more, the strategic goal of this trip can be regarded as basically achieved. Cao Cao's trip is not in vain if he accepts half of Runan as a buffer against Yuan Shu, and obtains thousands of yellow scarves, which can not only replenish troops, but also be used to open up wasteland effort.

It's just that Yuan Yao, who was forced to this point by me, can still make a strange move, which will really worry me in the future.

"It's a pity! This Yuan Gonglu really made him a good son!"

I sighed in my heart, Cao Cao made preparations that night, and at dawn the next day, he immediately led the army and slowly retreated towards the north.

However, after returning home, the sky full of lights left by Yuan Yao last night should be echoed in the hearts of everyone in Wancheng.

I'm afraid I can't forget it for a long time.

Chapter 283 The Gun King is a Good Brother

Cao Cao left, very resolutely, even faster than Zhang Xiu in Wancheng sent troops.

At dawn the next day, the tens of thousands of troops trapped outside Wancheng hurriedly withdrew to the north.

When Zhang Xiu led the Xiliang iron cavalry to set off, he found that he had no opponent.
