The most important thing about this kind of thing is to have a margin. Yun Zhonghe asked someone to dig ten oil wells, and even if two or three of them were unexpected when they were detonated, it would not affect the overall situation.

However, all this is based on the calculation and judgment of the No. 9 Quantum.

Because time is tight, Yun Zhonghe cannot really dig an oil well and see the crude oil erupt with his own eyes.

Moreover, relying on his own knowledge reserves alone, we cannot determine whether there is really crude oil underground and how deep it is underground.

But No.9 Quantum gave an answer, 99%.

This is almost the highest probability he gave. Whether it was the eruption of Dari Mountain volcano or the earthquake and tsunami in the Langzhou waters, it was far from such a high probability.

But Princess Wushuang is right. They all put their bets on Yun Zhonghe. If there is no oil underground or it is hidden very deeply, it will not gush at all, then Yun Zhonghe is really a sinner, causing the destruction of the entire army of Jing Zhongyue.

Yun Zhonghe smiled again and said, "Princess Wushuang, and my military order is clearly written. If my plan fails, you will cut off my head and let me follow more than 10,000 people to be buried with you."

Princess Wushuang looked at Yun Zhonghe for a long time and said, "This is my craziest moment. She actually followed you to make such a big bet."

"Open the city gate! Open the city gate!" At this time, there was a shouting on the city wall.

Jing Zhongyue rushed into Roulan City with thousands of cavalry.

In fact, she could delay the army of the Western Empire for a longer time, but Yun Zhonghe said that it would be enough to delay it for a day or two.

So, she really only delayed for one or two days.

………………………………

"Has it been done?" Jing Zhongyue asked immediately after rushing into the city.

"Okay." Yun Zhonghe said.

Jing Zhongyue's breathing suddenly became rapid, and the madness in her heart was ready to move again.

Her heart was filled with the urge to destruction. Before the entire hall was detonated, it was already a huge scene, which made her very excited.

The upcoming black oil gushed into the sky, like a black dragon soaring into the sky, but it was a scene that Jing Zhongyue had never seen before, and it was even unimaginable, but it was undoubtedly a bigger scene.

Yun Zhonghe said: "When the gunpowder explodes, flames will appear, and the black oil that gushes out directly, so it is not only black oil that sprays into the sky, but also shocking flames. Think about it, ten shocking flames are sprayed into the sky, and then falling down the rain of fire. How amazing and shocking this picture is?"

Jing Zhongyue's mind immediately had a picture, and her delicate body was trembling with excitement.

But she needs to go to the shower right now. She has been leading troops out these two days and has no baby to eat, so she is so angry that she feels very uncomfortable.

Zhongyue, who had walked out of the well more than ten meters, suddenly turned around and asked, "Who will detonate the gunpowder? Blow through the oil well?"

Yun Zhonghe suddenly fell silent because the suicide squad was going to do this. Although there was a possibility of survival and because the leads were very long, the mortality rate was very high, almost a life-threatening death.

"Yuan Tianxie's Huangtian Cult will act as a suicide squad to detonate gunpowder." Yun Zhonghe said.

Jing Zhongyue stood there, then remained silent for a moment, then continued to walk towards the Queen's Mansion, and quickly took a shower and changed her clothes.

……………………………………

"Young Master, you have made a terrible weapon come out in advance." Yuan Tianxie said.

Yun Zhonghe said: "There has been black oil in this world for a long time. I saw it in the relevant written records that it had existed a thousand years ago."

Yuan Tianxie said: "It is true that some people have used black oil a long time ago, and even I have tried it myself. On the land further west, even if you dig dozens of feet deep, black oil will seep out. Local herders will use it as a fire-driven object. But no one knows that it will gush out so wildly, and it will be astronomical. Then in the future, the catapult will probably throw this black oil bomb."

Nowadays, the catapult can also have fire attacks, but they are wrapped with straw ropes outside the stone bullets and then soaked with a little fish oil.

But once oil is exploited on a large scale, the cost of sulphur bombs will be greatly reduced. In this way, the future war will be even more tragic.

Yun Zhonghe said: "I'm very sorry, let your fanatical believers of the Huangtian Cult serve as the suicide squad."

Yuan Tianxie said: "As long as these 300,000 enemies can be eliminated, their sacrifice is worth it, or even proud."

Yuan Tianxie's brainwashing technique is indeed powerful. After the destruction of Dari Mountain volcano, he actually had so many believers.

"Here you come!" Yuan Tianxie suddenly said.

Yun Zhonghe looked up and his eyes suddenly shrank.

It's a super big scene, so shocking.

The 300,000 army was completely spread on the ground, and it was so amazing.

Yun Zhonghe had also seen the battle between hundreds of thousands of troops in Liefeng City, but the terrain there was narrow and the army could not be spread out at all.

But Roulan City is different here, with a flat horse and an endless Gobi Desert. Not to mention the 300,000 troops, even more troops can be let go.

"Bang bang bang bang..."

The army of 300,000 stretched for more than ten miles, and like a tide, the black and black rushed towards Roulan City.

Truly boundless, boundless, and boundless.

"It's impossible that it's all the troops of the Great Western Empire, right?" Yun Zhonghe asked.

"Fifty thousand is the army of the Great Western Empire, and the other 150 thousand is the army of many small countries in the Western Regions." Yuan Tianxie said: "In order to curry favor with Prince Li Zhou, and to have had a conflict with the horse bandit army in Jing Zhongyue before, they sent troops to attack Roulan City."

The footsteps of the 300,000 army resounded throughout the world, deafening.

Through several miles, Yun Zhonghe could feel the trembling of the earth.

Almost half an hour later, the 300,000 troops of the Great Western Empire stopped because there was a huge gully in front of them.

About five miles away from Roulan City, there is a long gully that stretches for hundreds of miles, almost completely surrounding Roulan City.

The widest place of this gully is dozens of meters, but the narrowest place is only two or three meters.

Between the huge ravines and the city wall, within this five-mile range, it is called the death area by Yun Zhonghe.

Three oil wells dug by Yun Zhonghe were distributed in this huge gully to break the flames and prevent the army from escaping.

The remaining seven oil wells are all in the death area that is five miles wide and fifteen miles long.

………………………………

In the army of the Great Western Empire.

"Your Highness, Roulan City destroyed the bridges on the ravines and the passages paved with soil." The scout came to report.

Many generals of the Great Western Empire army immediately sneered. This is not a big river, it is just a dozen feet of gullies. If you destroy the wooden bridge, we can easily build it.

It was a complete dream to try to stop us from siegeing the city with these tricks.

"Build a bridge!" With the command of the Great Western Empire army, thousands of baggage troops began to build bridges.

After all, it is just a gully, with the narrowest place being only about three meters, and dozens of wooden bridges are easily built.

Not only that, thousands of baggage soldiers also used soil to pave several gullies and restored the passage.

There is no problem with these dozens of wooden bridges passing through the army, and even war horses can pass through, but huge siege equipment, such as catapults, still have to pass through the dirt passage.

In just two hours.

The wooden bridge has been erected and the road has been paved.

"The army is advancing and surrounding Roulan City." With a command, the 300,000 troops continued to advance, walking through dozens of wooden bridges, and truly approached the city.

"All martial arts masters, climb the cliff and block the retreat of the well Zhongyue and Princess Wushuang, don't let them run away."

Thousands of martial arts masters under Prince Li Zhou rushed out and climbed along the cliffs on both sides to the top of the mountain. Dozens of them were the top strong men of Tianlong Pavilion.

Because the back of Roulan City is a mountain cliff, the Queen's Mansion is back against the cliff, Li Zhou was worried that when Roulan City was defeated, Jing Zhongyue and Princess Wushuang would escape from the cliff.

For this reason, Prince Zhou of Li mobilized hundreds of masters. These thousands of warriors were on the top of the cliff and carrying a lot of highly toxic drugs. I believe that even if Jing Zhongyue and Princess Wushuang have high martial arts skills, they will still be unable to fly.

"The Eagleman, climb to the top of the mountain. Once the well Zhongyue and Princess Wushuang escape from the top of the cliff, shoot the poisonous arrows immediately."

"Yes!" Hundreds of the most powerful archers also rushed out, climbed to the top of the mountain, and looked down at Roulan City.

"The army is advancing, advance!"

"Bang bang bang bang bang..." With the sound of drums, a large army of 300,000 was rushing towards the city of Roulan along dozens of floating bridges.

…………………………………………

Although it was only a few meters wide, it took several hours for the Great Western Empire troops to cross the bridge.

At dawn, all 300,000 troops of the Great Western Empire entered the death zone designated by Yun Zhonghe.

At this time, more than 10,000 troops under Jing Zhongyue and Princess Wushuang all went to the Roulan City Wall. The 15-mile city wall was made of soil, with a total of 10,000 troops, and an average of only one person was more than one meter, which was really sparse enough.

Such a city wall defense line is simply shabby.

Moreover, there are almost no cities guarding equipment, only three catapults, many bows and arrows, but there are not many giant crossbows, and there are not even a single one.

These more than 10,000 defenders were the iron-headed ones of Jing Zhongyue. They did not abandon her at such a moment and were already extremely loyal.

But they didn't know Yun Zhonghe's plan and thought they really wanted to fight this battle.

No matter how optimistic a person is, he will not dare to have any confidence in the face of these 300,000 enemy troops.

Therefore, the morale of more than 10,000 defenders in the well was extremely withered.

If a war really starts, at most half an hour, these more than 10,000 defenders will collapse.

Looking at the 300,000 troops under the city, the defenders of the well in the city wall were pale and their legs were trembling.

…………………………………………

Yun Zhonghe looked at the cliff behind the city and said, "The enemies outside the city wall will be destroyed by the fire dragon later. It is not fearful. What we need to be wary of are the enemies on the top of the mountain. Those people are either martial arts masters or sharpshooters."
