Seeing Third Uncle and Li Yu standing over there, Dapao said brazenly, "Those people ran so fast, chased me for a long time, finally caught up and dealt with them."

Li Yu and Third Uncle exchanged smiles, then said to Dapao, "Alright, as long as it's dealt with. Go rest for now."

As Li Yu and Third Uncle communicated, the sun set, and night fell.

The buildings on the horizon looked like those in an oil painting, the plains thickening into mist, a gray haze giving them an ethereal look.

Vaguely visible, some zombies emerged from the darkness, by the small river kilometers away.

From that direction, the sound of roaring continued.

"So fast?" Li Yu looked over in surprise.

These zombies came out as soon as the sky turned dark.

Immediately, Li Yu shouted to everyone, "Quick, speed up. Hurry and repair the walls, the zombies are coming."

In the midst of shouting, everyone's speed increased, originally Li Yu tasked Luo to find a solution for a big gate, Luo already had a solution.

The gate of Oil City stretches ten meters; if steel welding is used, it's simply too late, and can easily be toppled by zombies.

Under such circumstances, Luo simply used two tall dump trucks, and then welded the steel plate on the right side. As long as the two trucks are combined, they can form a door.

To open the door, generally, the space one truck creates when driven away is enough for most vehicles to pass through.

"Luo, is the gate done?" Li Yu asked through the walkie-talkie.

"It's coming." Luo answered.

Soon after, two dump trucks drove out from the central straight path, Luo personally drove one, the truck loaded with soil to add weight, making it immovable by zombies.

Luo drove to one side, then turned around, gently moving towards the gate position.

The vehicle rubbed against the nearby container, making a sound that made one's teeth ache.

But this is unavoidable; it must be tightly fitted so as to leave gaps for zombies to squeeze through.

The other truck was driven by Xiao Ding, both cooperating smoothly, the soil-filled dump trucks blocking the gap like two doors.

Besides the gate being closed, Old Bi, who didn't stop after entering Oil City, had already led people to repair most of the walls, only a small section remained, which was being stacked now.

Li Yu said to Third Uncle, "I'll go inspect the walls. Third Uncle, about what you just mentioned, I think we could try it. We'll discuss in detail once we've completely dealt with the Motorcycle Gang."

"Okay, you go east, I'll check the west." Third Uncle was also very concerned about the walls.

In Doomsday, the function of the walls is incomparable, it is the first line of survival for humanity.

The most important barrier against zombies.

The two split left and right, taking some people dispersedly leaving.

Outside Oil City, scattered fires burned; those were from Old Bi and his team clearing and cleaning the battlefield, piling up corpses, igniting them with oil.

The scattered fires lit up the surroundings of Oil City.

Within Oil City, Li Yu walked on walls built from stacked containers, which weren't considered high.

Previously, outside was another layer of barbed wire, but the daytime battle had mostly scrapped the wire.

Walking thirty meters from the gate, there were two large holes currently Ju Tianrui was carrying a sack of soil to place above.

Li Yu saw this, then held the soil on his shoulder atop the container.

Embraced the soil with both hands, feeling it wasn't heavy, likely seventy to eighty pounds.

He then single-handedly stacked it into the middle gap like stacking bricks.

The sack holding seventy to eighty pounds of soil in Li Yu's hand seemed light as a feather, placed atop several sacks full of soil.

Then he said to the others, "Bring the soil over, I'll do the stacking."

Ju Tianrui and the others looked at Li Yu, although they could lift seventy to eighty pounds of soil, stacking required careful placement to prevent collapse.

Typically it's two people on the container together lifting and slowly adding, relying on a single person can lift but is hard to control.

"Hurry up, why are you standing there stunned?" Li Yu frowned, shouting at Ju Tianrui and others.

Ju Tianrui and the others closed their mouths, quickly transporting.

Li Yu took a step forward, one foot on the lower container, the other on the sacks.

Single-handedly grabbing the soil sack from below, then switching to the left hand, eyes simultaneously looking left, precisely placing the sack from the left hand on the vacancy.

The soil-filled sacks, airborne while switching hands, fluttered but Li Yu managed the strength remarkably, light and effortless.

When the left hand put the sack down, gently and slowly, without bursting the sack from weight and spilling soil.

Li Yu's speed was almost one cement sack per second, piling atop.

Below, Ju Tianrui and over ten others saw Li Yu's rapid pace, had to sprint to barely keep up.

A minute later.

The gap was fully stacked.

Ju Tianrui heaved large breaths, looking at Li Yu like a monster, never expected Li Yu could be this strong.

Huff, huff, huff—

Not just him, others below also looked with admiration at Li Yu.

Li Yu's breath remained steady, those moves earlier weren't truly exhausting for him.

He waved a hand, saying to them, "Zombies are coming soon, hurry to other locations and help."

Finished, he continued inspecting Oil City walls.

After walking over a hundred meters, mostly without issue.

Suddenly, he stopped, looked ahead at the girl in a black vest, also repairing the walls.

Her actions remarkably similar to what he did beside Ju Tianrui.

Shen Xiaoxiao atop, calm and breezy, single-handedly holding soil sacks, below Zhong Chuchu and others were worn like dogs.

"Haha." Li Yu saw this, smiling.

"Not bad."

.......

Soon, Li Yu circled the walls, helping where needed.

Seven or eight minutes later, he met Third Uncle on the wall.

"No issues on my side."

"Mm, my direction is sorted too." Third Uncle nodded.

Afterward, Li Yu returned to the gate direction, wanting to see where the zombies were, he had a very important matter to attend to.

This matter, he considered countless times.
