Li Yu hurriedly arrived at the gates of the Oil City fortress and saw Guan Zhongjin still sitting on the ground.

At this moment, Guan Zhongjin's face was full of pain, surrounded by people, he couldn't find any chance to escape.

Li Yu only glanced at him, then cast his gaze outside the Oil City fortress. In the time he went to check the walls, zombies from several kilometers away had already reached the outside of the Oil City fortress.

The air was filled with the smell of roasted meat and burning oil, an indescribable stench.

Li Yu saw the zombies were not afraid of the flames at all, directly walking toward the still-burning bodies.

In the raging flames, each zombie was coated with fire.

These zombies had no consciousness, some gnawing on the charred bodies, stained by oil, were consumed by the fire and collapsed.

Li Yu found the scene bizarre beyond words.

Unexpectedly, Old Bi and Ju Tianrui dealt with those bodies and achieved such effects.

Suddenly, he also understood why the Oil City fortress could survive wave after wave of zombie tides, despite its walls not being that high and being defenseless against the Motorcycle Gang.

It relied on the oil within to resist the zombies.

They only needed to bury a circle of oil around the Oil City fortress, and when zombies attacked, ignite the oil to effectively resist the zombie tide.

Even in a downpour, the rain couldn't extinguish the flames.

The reason rain couldn't put out the burning oil is because oil's density is lower than water. When water is poured onto the oil, the oil floats on the water surface, contacting air (oxygen) and continuing to burn.

The biggest drawback of this method is the consumption of a large amount of oil each time, but for the oil-rich Oil City fortress, it's not a disadvantage.

Third Uncle watching beside him slightly nodded.

He spoke: "It seems Oil City fortress is indeed suitable for long-term residency, the oil resources here are abundant and highly useful."

Li Yu agreed, saying: "Yeah, I didn't expect it to be so effective. It seems every place that hosts large survivors has its reasons."

As Li Yu spoke, he watched the zombies outside rush toward the burning bodies like moths to a flame. 𝚏𝕣𝐞𝗲𝐰𝕖𝐛𝐧𝕠𝕧𝚎𝚕.𝐜𝚘𝗺

Not in a hurry, he glanced at Guan Zhongjin.

Then he sat on the container, quietly waiting.

He didn't kill Guan Zhongjin immediately because he wanted him to feel what it's like to be engulfed by the zombie tide.

Since the zombies weren't here yet, they waited. Li Yu had patience.

The oil had been burning for more than half an hour, the oil was durable, and despite being burned for so long, it showed no sign of extinguishing.

Over time, more zombies appeared outside the Oil City fortress, most gathered around the flaming bodies gnawing.

Gradually, those bodies burned into charcoal, and some zombies, fully engulfed in flames, didn't die immediately but came to the container wall.

These flame-covered zombies didn't last long, burning until they collapsed.

An hour later.

The flames finally went out.

Li Yu sighed, the oil was incredibly durable, and they hadn't placed much oil on the bodies.

Looking at the increasing number of zombies under the wall, Third Uncle thought for a moment, then said: "How about we try using pipes to connect to the oil inside, and spray a circle of oil along the wall with a spray gun?"

Li Yu glanced at Guan Zhongjin, shook his head and said: "Wait, there's something I haven't done yet."

After speaking, he jumped down from the wall.

Thud, thud, thud—

He slowly approached Guan Zhongjin.

During this time, Guan Zhongjin had been thinking about how to escape, but his hands and feet were tied, surrounded by people, leaving no chance, so he was forced to sit quietly on the ground.

He kept wondering why he was being kept alive, why hadn't they killed him, what was the purpose.

Getting on someone's bad side, what sort of reason was that?

Could the leader of this group be a psycho, who loves torturing people?

Thinking of this, Guan Zhongjin shivered all over.

He lowered his head, saw the boots in front of him, then raised his head to see Li Yu's face, which he feared.

Li Yu wore a cruel smile, looking straight at him.

Li Yu's face, illuminated by the car lights behind, made his smile terrifying.

Guan Zhongjin's eyes showed fear, and he moved backward, "What do you want?"

Li Yu didn't answer, instead directly grabbed his arm, pulled him up forcefully, and dragged him towards the wall.

"What do you want?" Guan Zhongjin was confused, not knowing what Li Yu intended.

But soon, he realized Li Yu's intentions.

Li Yu brought him up to the wall, he saw the roaring zombies below, turned to Li Yu, and suddenly understood.

This man wanted to push him into the zombie tide, to feed them!

Guan Zhongjin struggled vigorously, even though he was heavily injured, he still wanted to live.

But his struggle was futile, Li Yu's grip on his arm was like steel, preventing any resistance.
