When Zhao Yi was thinking about where to go next, Xu Yue'er came back pushing a huge black water ball.

Zhao Yi glanced at the water polo, was stunned for a moment, and then couldn't help but raise his eyebrows.

It was the first time he knew that there was also oil in the world of cultivating immortals.

But that's normal.

According to Zhao Yi's textbook in his previous life, the source of oil was the movement of the earth's crust, which caused trees and animals to be buried in the ground, and then formed after tens of millions of years of accumulation.

There is nothing else in the world of cultivating immortals, trees and wild animals are all over the world.

These things are the most basic material conditions for the formation of oil.

But.

Zhao Yi was curious, how did Xu Yue'er find these oils?

Could it be that dragons still have the potential to be geogeologists?

Looking at the oil balloon, Zhao Yi asked Xu Yue'er: "How did you find these things?" ”

Xu Yue'er replied naturally: "The dragon clan is born with water control, and the black oil also contains water, whether it is to find or control it is not a problem for the dragon clan!" It's just that the black oil is sticky, and the smell is unpleasant, and the dragons don't like this thing very much. ”

Is that okay too?

Zhao Yi's eyes were immediately opened, and then he waved his hand: "You want to burn those monster corpses with black oil, right?" That's a good idea, go for it. ”

Zhao Yi also knows that oil combustion produces many harmful substances, which can cause significant pollution and damage to the environment.

But it's not like there's no one in the world of cultivating immortals now.

And no one will come back anytime soon.

In this case, burning some oil is not a problem at all, and even if it pollutes the environment, it can be restored after a few decades.

There is one of the most important reasons why Zhao Yi agreed to Xu Yue'er to use oil, that is, he is really fed up with those stinky otherworldly monsters.

These monsters were already stinky enough when they were alive, and when they were burned with fire after a while, Zhao Yi couldn't imagine how much those ghost things could stink.

The oil is thick and highly adhesive, and it is used to dispose of these corpses.

Moreover, the smell generated by the use can also suppress the stench of monsters.

For Zhao Yi, those stinky monsters are the biggest source of pollution in this world!

After Xu Yue'er got Zhao Yi's permission, she didn't hesitate any longer, and directly pushed the water balloon to the top of the center of the corpse, and then controlled the water balloon to release oil outward.

Thick oil flowed out of the balloon, quickly concealing the monster corpse below, and then slowly flowing in all directions.

Only then did Zhao Yi realize that the oil bead pushed by Xu Yue'er was actually compressed.

The water balloon didn't look big, only two zhang in diameter, but with the continuous release of it, it soon drowned all the monsters within a radius of more than ten miles.

Seeing this scene, Zhao Yi suddenly sighed.

Regarding the dragon clan's ability to control water, Zhao Yi finally had a clear understanding.

The oil balloon compressed by Xu Yue'er was placed in Zhao Yi's previous life, and the oil in it was at least several million barrels.

If it was in Zhao Yi's previous life, Xu Yue'er would have been able to open an oil transportation company with this skill, and she would definitely be able to make a lot of money.

In addition to oil, transporting water is also big business.

There are many places where there is a shortage of water on the Blue Star, and Xu Yue'er can completely monopolize the water resources trading business of the Blue Star with this skill.

Unlike oil, water doesn't cost money.

Specializing in doing business with countries that have been hit by floods.

Wash away the flood water from their country and sell it to those countries that are short of water.

Eat two of them.

Xu Yue'er can definitely become the richest person in the entire Blue Star in the shortest possible time.

Zhao Yi was bored, thinking nonsense beside him, while observing the difference between the oil in the Immortal Cultivation World and the one on the Blue Star.

As it turned out, it was no different.

Under the same geographical and climatic environment, the composition of oil does not change in particular.

Like the Blue Star, thick oil simply cannot be ignited directly.

Zhao Yi saw that Xu Yue'er hadn't lit it after trying several times, and just as he was about to open his mouth to point, he saw Xu Yue'er turn around and go to the woods next to him.

When Zhao Yi saw this, he immediately knew what Xu Yue'er had in mind.

Really.

Not long after Xu Yue'er left, the two dragon claws grabbed a huge log and came back.

She flew to the center of the monster's corpse, and with the force of both claws at the same time, she directly crushed the log into a pile of debris and landed on top of the oil.

Rumble!

Xu Yue'er hit it with a spell, and the sawdust piled up high was instantly ignited.

Under the fire, the oil was heated by the scorching heat of the firewood, and then gradually boiled and began to burn.

The process of burning oil is very slow, but once it is ignited, the burning posture instantly spreads like a spark to the prairie and spreads out in all directions.

In the midst of the oil, the corpses of the monsters wrapped in them began to burn slowly under the heat of the fire.

The air soon filled the air with a strange smell with a strange smell of odor.

Zhao Yi looked around the pungent smell, and quickly thought of something, and suddenly felt a range.

He vowed never to eat stinky tofu again in his life!

"Let's go."

After the oil was ignited, the fire grew bigger and bigger, and soon became a sea of fire at the gate of Shengjing City.

Zhao Yi glanced at it, turned around and prepared to leave this land of right and wrong.

On the one hand, the corpses of otherworldly monsters are soaked in oil.

Now that the fire has already burned, it is impossible to stop without burning all the monster corpses, so there is no need to wait here any longer.

On the other hand, the smell in the air is just too bad.

When those monsters died, there was only a stench in the air.

Nowadays there is not only the stench of monsters, but also the stench of burning oil, and the smell of barbecue.

All kinds of smells are mixed together, and the smell is almost life-threatening.

Xu Yue'er burned an unknown number of otherworldly monsters with her own hands before, and at this time, she burned all their corpses, and the revenge was avenged, and the resentment in her heart and the emotion of almost annihilation were reduced a lot.

Hearing Zhao Yi's words, she hurriedly agreed, and then obediently flew to Zhao Yi's feet, dragging him to take a detour in the direction of the prince's mansion in Shengjing City.

Xu Yue'er knew very well that the reason why she was able to take revenge was entirely because of the person in front of her.

If it weren't for Zhao Yi giving her a chance and being said to have taken revenge, Xu Yue'er might have become food in the monster's mouth now.

Therefore, after hearing Zhao Yi's order, Xu Yue'er showed unprecedented respect and obedience.

Zhao Yi didn't know what Xu Yue'er was thinking, and even if he knew, he didn't care.

When the Four Seas Dragon Clan was in its heyday, Zhao Yi didn't take it to heart, let alone that now there is only one Dulong left.

If Xu Yue'er is obedient, Zhao Yi doesn't mind keeping her as a mount.

After all, it's quite face-saving to ride a dragon out.

If Xuyue'er doesn't know each other, the boar monster can slay the dragon, and gluttony can do the same!
