The massive tide of zombies rushed over, and after being bombarded by more than a hundred artillery pieces of various types,

The tide of corpses stagnated, buying time for the oil formation to open.

Ten minutes later.

Crack!

Outside the outer wall of the trading market, with the opening of the oil array.

Oil flows from the Oil City, through the underground pipelines of the trading bazaar, to outside the walls of the trading bazaar.

Boom!

A cannonball exploded in the zombie wave, igniting the oil at the same time.

Amid the explosion, a flame more than ten meters high rose up.

Hundreds of artillery pieces of various types bombarded the area, igniting the oil in the oil array at many points outside the wall.

Swish, swish, swish!

The burning flames broke out at multiple points, connecting the points into lines, and the lines into surfaces, and soon formed a sea of ​​​​fire.

The area covered by the Petroleum Array is centered on Petroleum City and covers a surrounding area of ​​four kilometers.

These four kilometers are now burning with raging fire.

Stab, prick, prick—

The sound of the burning flames was a bit harsh.

The heavy rain falling from the sky not only failed to extinguish the flames, but actually fueled them.

Because oil and water are incompatible, and oil is lighter than water, it will float on the water.

It will increase the surface area for oil and gas contact, and the fire intensity will increase after the oil and gas are fully contacted.

The fire became more and more fierce.

The zombie's body itself contains a lot of flammable decaying substances, and if it is contaminated with some oil, it will burn more easily.

In the sea of ​​zombie fire, all you can see are burning zombies.

These zombies are like dry firewood. Once lit, they can only be extinguished by burning into ashes.

The fire made the sky red. The guards on the wall of the trading market closest to the sea of ​​​​fire all had their faces turned red by the fire.

mountains of corpses and seas of fire,

These four words fully express what Chen Er and others saw.

Countless waves of zombies burned in the flames.

There was a putrid and burning smell in the air that was nauseating.

In the trading market.

Many survivors ran out of the houses. Looking at the shells flying in the sky, the whole sky was reflected red.

There was a lot of discussion among the crowd:

"Is there a fire outside?"

"It seems like hey, I heard there seems to be an oil array here? When we entered the trading market, didn't you see those small ditches? That should be the one."

"This trading market is so fierce, with so many tricks!"

"Yes, I saw the knife when I came in. It seems to be used to defend against zombies."

"No wonder Oil City is so confident. It's the right time to come here."

"If we didn't come in, we would probably have died in the thunderstorms a few days ago. I still think the thunderstorms some time ago were more terrifying!"

"Have you never thought about how much oil this consumes?"

"I'm afraid you have forgotten what this place is. This is called Oil City. It was originally a place that could produce oil. The most indispensable thing is oil."

"Damn, I almost forgot about this, this oil city is so scary!"

.....

After seeing the flying shells and the burning oil array outside, many survivors were shocked by the powerful foundation of the Oil City.

Most people are very happy that they have entered the trading market.

With the weather these days, they are not very confident that they can survive.

But now they can still stay here safe and sound.

A feeling of joy arose spontaneously.

...

The area where Southern Paradise personnel are located.

Mr. Hu walked out of the room. Even standing here, he could still feel some heat coming from outside. You can imagine how big the flame was!

"Master Hu, this should be what they call the oil array. Look at the sky being burned red, and I don't know how much oil was used. It's so luxurious!" Wu Xing looked at the sky and sighed.

luxury!

Their Southern Paradise needs to come up with various supplies to exchange for fuel with Oil City.

Every time you exchange the fuel, you must use it sparingly.

But this oil city directly takes so much oil and uses it to burn zombies!

I'm afraid that the amount burned this time alone is at least dozens of tons.

Otherwise, such a large-scale sea of ​​​​fire would never be possible.

After all, it surrounds the entire trading market in such a large area.

Master Hu was wearing slippers, looking at the red clouds in the sky, and said with emotion:

"It seems that the effect of stopping zombies should be pretty good."

As he spoke, he frowned slightly.

I feel like my breathing is not smooth.

Wu Xing next to him gasped twice and said:

"Am I the only one who feels a little suffocated?"

"Why do I feel like there's not enough oxygen?"

A person next to him quickly said: "Brother Angkor, I also feel a little dizzy. Is the smell of these burning zombies poisonous?"

"How is it possible? It's only a few years since the end of the world, and we still don't know how zombie infection spreads. It can only be done through biting and breaking the skin!" said another person.

Master Hu frowned and looked at the fire on the horizon.

"Combustion requires oxygen in the air. The combustion of such a large oil array will extract a lot of oxygen in an instant, which will definitely lead to some hypoxia."

Hearing Master Hu say this, everyone was a little worried.

"ah?"

The surrounding men asked in panic:

"Then will we suffocate to death!?"

Wu Xing cursed: "How is it possible? Our place is not completely enclosed. Isn't there still air circulation in the sky?"

"right."

Master Hu took a deep breath and said:

"Don't worry, everyone. Although there will be some hypoxia, it will definitely not be fatal."

When everyone heard Master Hu say this, they breathed a sigh of relief.

But the feeling of lack of oxygen is really uncomfortable.

.....

Wall of trading market.

Zhu Xiao felt hot all over. He stretched out his hand to touch the wall in front of him and felt a little hot.

They were closest to the sea of ​​zombie fire, and the rainwater on the wall was baked and hot.

He quickly took a few steps back.

Sweat beaded on his forehead.

The rain is still falling, lowering the temperature slightly.

But the feeling of being unable to take a breath made him extremely uncomfortable.

Chen Er looked a little depressed and said to Zhu Xiao:

"Have you used this oil array before?"
