The new recruits and veterans in charge of the turret moved their eyes to the blue sky with Bai Jin's magic circle.

I saw a huge magic circle spreading over Benliang City, releasing dark clouds as thick as ink.

There was no lightning and thunder, a black raindrop fell on the forehead of a veteran guarding the fort. The recruit next to him also reached out to catch a black raindrop.

The two of them pinched the black raindrops with their index fingers and thumbs at the same time.

The black liquid is as sticky as an egg. When you get close to your nose, you will smell it a little bit of rotten eggs. It is very pungent and makes people feel very uncomfortable.

Pick, snap, snap, and more and more black raindrops fell from the air.

The magician opened the defensive shield.

Looking at the black raindrops hitting the defensive shield, they looked confused.

They all knew it was a magic to manipulate the weather, but they had never seen such black rain.

As a magician, General Scarlet also participated in the construction of defensive magic.

These black rains did not freeze due to the severe cold of the Serovo Gate and drizzled constantly.

An ominous premonition arose in General Scarlet's heart, as if the black god of death was approaching them quietly.

The black raindrops falling from the sky are oil.

What Yang Yu is looking for in the swamp is the natural asphalt lake, and underground oil that surges along natural cracks and flows out of the ground.

Thanks to the help of Oias and the wild boar orcs, Yang Yu spent almost no time to find the "oil seedlings" in the asphalt lake.

As the blood of modern industry, oil is well known to everyone.

When Yang Yu first saw the "oil seedlings", he also felt a lot of uneasy, but the quality of the "oil seedlings" they found was beyond imagination.

By sinking into the bottom of the "oil seedling", Yang Yu could almost get oil of the best quality and almost never oxidized.

It has not yet been developed and mixed with silt and sand to become asphalt, and it has many volatile combustible substances.

Imagine it carefully!

If the rain in the sky is crude oil, the drizzle will definitely evaporate the substances in the oil, and those combustible gases will definitely permeate the city.

If there was a little Mars at this time, what would it be like?

It will surely cause unimaginable huge explosions and fires.

It's like a cigarette butt, which can induce an explosion at a gas station.

Those are lessons of blood and tears.

Oias stood up from Lotkar, and a specially made arrow had already appeared in her hands.

The arrow of this arrow is painted with white phosphorus.

Yang Yu has done experiments with Oas's must-see marks.

When the arrow disappears, it seems to have traveled through a different dimension, and the rate of fire and state are basically unchanged. It is the most suitable to ignite this "heavy rain".

When Oas pulled the arrow, Yang Yu also took out a moor bottle.

If the flame on Oias' arrow disappears before it touches the city wall, Yang Yu will take a second insurance.

However, before Oas could release the string, a huge explosion came from inside the Liangcheng.

The embers left by the logistics of the Luoze Empire cooked at noon helped Yang Yu and the others ignited the "heavy rain" in advance.

The soldiers of Luo Ze on the city wall were startled by the sound inside the city. They turned around and saw endless flames hitting them.

As the flames advanced, explosions in the city began one after another.

The rolling red flames were like a demon.

Just now, Luo Ze's troops were in a mess, and they threw down their weapons and fled everywhere.

Seeing this scene, Yang Yu was not very happy, but just clenched his fists and issued an order to Oas:

“Hand it.”

With Yang Yu's order, the arrow in Oas's hand drifted across the sky, and a white smoke emerged in the air.

As the arrow was about to burn, the whole arrow disappeared into the void.

When the arrow appeared again, the white phosphorus on the arrow rubbed violently with the air, dragging out a long white flame.

Before the arrow touched the wall, it directly ignited the surroundings of Liangcheng.

A fire accompanied by the explosion, climbed rapidly along the city wall washed by black rain. Before the fire in the city flooded the Luo Ze soldiers on the city wall, he swallowed the Luo Ze soldiers first.

The shells used by the cannons of the Luoze Empire exploded under the scorching flames. The terrifying explosion sounded one after another, completely shattering the city walls. The stones burning with flames fell into the sea of ​​fire outside the city.

The thick flames spewed out endless tongues of flames, releasing black smoke, and in a blink of an eye it swallowed up the Liangcheng and burned into the endless sky.

There is only a piece of fiery red left around this Liangcheng.

In an instant, screams came one after another, and figures ran around in the fire.

Some fell into the flames and turned into ashes; some jumped directly from the city walls, broke their legs, and were finally engulfed by the fire. Occasionally, a few soldiers who escaped from the sea of ​​fire fell to the ground when they arrived at a place without fire, rubbed hard, barely extinguishing the flames on their bodies, but they were like charcoal and dying.

No one expected that in just a few minutes, the hellish scene would appear alive in front of you.

Seeing all this, the three orcs responsible for manipulating the memory crystal had a nausea and almost failed to maintain the operation of the memory crystal.

At this time, they had no hatred in their hearts, and they had only mercy on the soldiers of Luo Ze who were guarding the Liangcheng.

Putting away the mould bottle in his hand, Yang Yu clenched his fists and his nails were deeply embedded in the flesh.

He looked at Benliang City with the fires surging, and didn't know what to say.

Although he had already made up his mind, such a cruel scene appeared in front of him, and he couldn't help but shake his heart.

He raised his hand and clenched it tightly, slowly letting go. Yang Yu could see that his hand was trembling slightly.

And the tremor on his hands was like a disease, spreading from the palm to the arm, from the arm to the shoulder, from the shoulder to the chest...

Yang Yu raised his other hand and held the trembling hand tightly. The trembling was stopped.

Without looking at the fire in front of him, Yang Yu turned to the boundless sky and muttered to himself:

"If you still have a little mercy.

It's time to come out...

If it's a little later, I don't know how many people will die this time."

It was as if responding to Yang Yu's expectations, and a crack tore the sky without warning.

A huge red dragon crawled out of the crack. She flew over the Liangcheng City, opened her mouth, and spit out a white dragon breath.
