The Chao truck signaled to the left.

"Adjust direction!"

…

Zhao Guang and Yang Wanwan stood dumbly behind Feng Yong, watching the person operating the rock dump truck shouting unintelligible terms. This was not the use of the rock dump truck as they knew it.

The method, I feel unclear about it.

The Cao soldiers at the top of the city gradually stopped laughing. No matter how stupid they were, they could still understand that the power of the trebuchets of the Han army on the opposite side should not be underestimated as they watched stone after stone flying over their heads and falling into the city.

But why do they only throw one stone at a time?

"Brother, let everyone smash it together!"

Zhao Guang stepped forward and said excitedly, "Such a good thing, if one hits a stone, it's useless..."

He originally thought that what his brother ordered to make was just an ordinary trebuchet, but he didn't expect that it was such a powerful siege weapon.

"What do you know? Watch carefully, this is called a test firing! If you want to use this thing when you lead troops in war, you have to know how to use it."

Feng Yong scolded.

…

"Test firing on the 10th is completed!"

After all this hard work, the sun has reached mid-air and all the fog on the mountains has dispersed.

Wenshi came over and saluted Feng Yong, "Feng Langjun, you are ready."

Feng Yong nodded and ordered, "Let's begin."

"promise!"

Behind each riprap truck, something was covered with a felt, and there was a pile of sand and soil around it.

A soldier opened the felt cloth, and underneath were jars wrapped with straw rope or hemp rope.

After closing the gate, Cao Bing discovered that the objects thrown by the Han army on the opposite side began to increase. It was no longer a single stone, but dense black shadows, like giant locusts flying above.

It's just that they were all a little confused. The Han army's catapults were really powerful, but their throwing was too bad. Not many of them hit the city wall, but most of them fell into the city.

There was a "crash" sound, and something hit the arrow tower diagonally, making a shattering sound.

"What is this? Why is it a piece of pottery?"

Some soldiers curiously picked up the fragments that fell on the city and looked at them. They laughed and said, "Could the Shu captives have gone crazy? They used clay pots to attack the city?"

Pang Hui walked over, picked up a piece of pottery and looked at it. He saw that it was greasy, as if it was used to hold oil.

Oil?

Pang Hui thought of this, his heart suddenly lurched, and he shouted, "No! Hurry, go to the city to get water!"

Unfortunately, his reaction was still a little late.

At the foot of Guancheng, some of the soldiers operating the trebuchets soaked a felt cloth in tung oil, then wrapped it around the stone, wrapped it tightly, placed it in the leather nest of the trebuchet, and lit it.

"put!"

The burning stones flew out and fell into the city.

With a "boom", the wooden house that had been covered with tung oil suddenly burst into flames. The fire spread very quickly, and in the blink of an eye, a small area turned into a large area.

On this end, the soldiers quickly shoveled up the sand and buried the newly ignited leather nest. They dug it out when the fire was extinguished, pulled it and felt it was still strong, and then continued to use it.

At the top of Longguan City, clay pots filled with tung oil kept flying over, and occasionally burning stones fell into the city, causing fires everywhere.

The houses in Guancheng are all made of wood, so they are naturally waterproof.

Cao Bing carried water and poured water on the burning house. Unexpectedly, as soon as the water fell on top, the fire suddenly jumped up and licked his face directly. Cao Bing covered his face and screamed.

Go back.

Crackling!

The huge tongue of fire jumped up happily, as if thanking Cao Bing for the bucket of water.

Houses began to collapse and sparks rose into the sky.

From time to time in the city, humanoid fireballs rushed from burning houses onto the streets, rolling over and calling for help.

"Quick! Get some people down to put out the fire!"

Cao's soldiers obeyed the order and rushed down the city wall, but the fire on the street was so fierce that they forced some of them back.

Pang Hui's face turned pale. He really didn't expect that the other party would be so vicious that they would attack the city with oil and fire. They were planning to burn all the people in the city alive!

But where do they get so much oil?

Where did such a powerful trebuchet come from?

Why is the projectile so accurate?

All kinds of doubts flashed through Pang Hui's mind, and his heart was on fire.

Cao's soldiers below were running back and forth carrying water, trying to put out the fire, but for some reason, the more they poured water, the bigger the fire became.

Wooden houses are prone to fire, and with the help of tung oil, it didn't take long for the fire to spread throughout the city.

However, Guancheng was only a little over a mile in radius, and the fire was so powerful that even Pang Hui, who was standing at the top of the city, was roasted to the point of sweating like rain.

Feng Yong, who was standing under the pass, looked at the billowing black smoke rising from the city. He didn't need to look up to see the signal from the Chao truck, but he already knew that the fire in the pass was unstoppable.

Fire attacks require the right time and place to launch.

People of later generations have a very common question when discussing the Three Kingdoms: Why didn't Cao Cao use arrows when he borrowed arrows from a straw boat?

So many people debated it from the perspective of romance, or from the perspective of historical facts, or even added their own ideas and so on.
