Time is the most ruthless existence in the world, it will not change because of your mood, let alone time stand still.

No matter how it passed, the three days had quietly arrived.

During these three days, Liu Wu's army subverted the past, the whole army went out day and night, and the camp was closed, and the whole atmosphere was very tense.

A wooden sign was erected in front of the military village, which read: Those who are close to the military village will be killed!

No one knew what kind of medicine Liu Wu was selling in the gourd, and the coalition forces were itching.

Since Guo Jia reached a gambling contract, the atmosphere of the army has changed dramatically, and it is extremely restrained, and at this moment, he has a bird's-eye view of Liu Wubu's military camp from the air.

On the neatly laid ground, straw curtains woven from hay are neatly arranged, and under the straw curtains are huge wooden barrels, arranged in a rectangular shape.

This is not the end, there are even more sheltered corridors in the sky, making the hot weather look very cool underneath.

Why did Guo Jia bet that everything was because of the neatly stacked wooden barrels in front of him, and the secret weapon of this battle was installed in the barrels.

……

"Woo ......"

"Knock ......"

The drums of war were endless, the horns were constantly sounding, and the war began.

In order to test the promise, it is better to observe the battlefield situation, and ask Sun Jinghui, the commander of the Jingzhou coalition army, to personally lead the army to encircle, and the commander of the four-way partial army will accompany the commander.

In front of the south gate of Linyuan City, Liu Wuqi stood here, with fifty ultra-long stone throwing machines lined up behind him, and the soldiers of all the departments stood with their heads held high.

Fifty stone throwers were divided into two rows, each with twenty-five units, and twenty well-sealed barrels were neatly placed behind the stone throwing machine.

Guo Jia's eyes were firm, but there was a hint of melancholy in his firm eyes, and he sighed lightly: "Sacrificing this killing weapon today will have too great an impact on the future war." ”

After hearing this, Xun Yu couldn't help but sigh with emotion: "However, this move is really too hurtful, and our army must not use this trick unless it is a last resort in the future!" ”

In the face of Jiancheng, if the 5,000 soldiers under Liu Wu were relied on to attack, even if there was a strong army under his command, it would be impossible to take Linyuan City with conventional siege methods.

So if you want to capture Linyuan City, you must come up with a different way.

Before making a bet with Xin Chang, Guo Jia had already thought of a countermeasure, since it was a fire attack, he couldn't burn a giant city with conventional methods.

In addition to dry firewood, there is still fierce fire oil in this world, and fierce fire oil is made of extremely flammable tung oil, and the consumption of burning the giant city of Linyuan City is too great.

Therefore, it must be like a new countermeasure, when rushing to Linyuan City, the scout accidentally found a puddle of black oil in a mountain range more than thirty miles away from Linyuan City.

This unexpected discovery made the scout report to Huang Zhong immediately, Huang Zhong felt that the black oil was very strange, so he gave it to Liu Wu, who happened to be discussing military discussions with Guo Jia, Zhou Yu, and Xun Yu.

At that time, after listening to Huang Zhong's description, Liu Wu felt very amazing, and said without thinking: "Isn't this oil?" ”

Out of curiosity, Guo Jia asked what oil was, so Liu Wu didn't feel anything, so he told everyone about the nature of the oil.

Although the matter was over in the end, Guo Jia kept it in his heart.

Petroleum is an extremely burn-resistant crude oil, and if it ignites, if there is a large amount of oil accumulation in the area, it will be destructive to the ecological environment of the place.

Since Liu Wu didn't know what kind of world he was in now, he wasn't sure why oil springs appeared in the south.

Everything is unsolved.

Why do Guo Jia and Xun Yu have such feelings, because they have already understood the threat brought by oil, and why Liu Wu's army has been out day and night in the past three days, it is entirely because they don't want others to know about the big killer of oil.

At the head of Linyuan City, Wu Yi and a group of generals of the Jingzhou Army are here.

Wu Qilin gritted his teeth and looked at the camp under the city wall, and said hatefully: "Damn, then Liu Wu's army has finally appeared, and the young master has been waiting for them for a long time!" Father, son, fight! ”

Wu Yi didn't pay attention to the indignant Wu Qilin, but looked at the front of the formation intently, and said calmly: "Don't be in a hurry, and see what Liu Wu wants to do." ”

Not only Wu Yi and the others wanted to know what Liu Wu was going to do, but even Sun Jinghui and them, especially Xin Changna, were looking forward to seeing when the east wind that Guo Jia said three days ago would come.

Seriously, Guo Jia is not a god, and he will not let the east wind blow in the sky.

But what makes people feel amazing is that as time passes, a breeze blows on the originally hot and windless battlefield, and the wind is getting stronger and stronger!

Xin Chang, who was watching the battle from a distance, was shocked when he saw the flag fluttering in the wind: "How can this be ......?"

Not only Xin Chang was shocked, but Sun Jinghui also felt quite amazing.

Some people may ask, why did Guo Jia predict that there would be an east wind today? For strategists, it is necessary for them to observe the sky at night, although it is very accurate to predict it.

Guo Jia is a good reader, when the army conquered the counties, he would collect books and learn from the books, and Guo Jia read a county chronicle of Wuling County.

Combined with the description of the book, coupled with watching the celestial phenomena, it also made him speculate that when the east wind appeared, this is not magical, as long as you are willing to learn, all magical things in your eyes are actually just an expression of magical nature.

Seeing that the east wind was blowing in the sky, and the wind was expanding, Liu Wu suddenly raised his knife and pointed to Linyuan City, and said sharply: "The stone thrower is ready to ......."

The soldiers who stood neatly and neatly divided into fifty teams rushed to the catapult according to the order, and the huge wooden barrels that were covered were placed on the belt of the catapult with the help of the strong soldiers.

The sharp blade made a small opening in the barrel, and a huge strip of cloth wrapped around the barrel, and suddenly a pungent smell came to the face.

"Boom ......"

A soldier appeared with an unlit torch and lit it with a flint.

Liu Wu glanced at Linyuan City in front of him, and said secretly in his heart: "I hope you can still survive, and then we will fight again!" ”

No one knew who this was said for, and immediately, Liu Wuzhen shouted: "Throw ......"

The soldier holding the torch placed the torch on top of the cloth strip with neat movements.

"Boom ......"

The fireworks enveloped the entire barrel in an instant, and then the soldier holding the huge mallet smashed the catapult device in anger!

Fifty stone throwers threw into the air fifty barrels of wooden barrels wrapped in flames, and the fireworks hung in the air like fifty suns.

"Whew......"

At this moment, everyone looked up into the air without thinking, at the burning barrel.

And this seemingly small wooden barrel in the air will be the key to the battle situation in Jingzhou.
