Chapter 1771 The Main City Wall of Youzhou Base

Li Luo carefully examined the defensive facilities along the way while listening attentively to Qin Fenglin and Li Nana's introduction, her eyes full of focus.

"Further into the mountains and forests, ten mobile patrol teams have been deployed," Li Nana added, her tone certain. "Each team consists of five superhumans and ten elite soldiers, equipped with off-road vehicles, reconnaissance drones, and portable missile launchers. They patrol 24 hours a day, leaving no blind spot unchecked. Last time, a small group of level-three zombies tried to sneak past the buffer zone, but before they even entered the core alert area, they were spotted by the patrol team's drones. Superhumans were dispatched to wipe them out from a distance, and they were all destroyed before they even reached the edge of the city wall."

"So strict?" Shi Xinxin gasped, instinctively shrinking back into the car window, her face full of surprise. "What if they encounter a large-scale zombie horde or high-level zombies? Can this patrol team hold them off?"

“This is where the main city wall and energy shield come in handy.” Following her words, Qin Fenglin pointed to the main city wall that was becoming clearer in front of him, and his tone became more serious. “Look, that city wall is the real impregnable fortress. Even if the shield fluctuates briefly, it can still steadily withstand the attack and will never let the danger rush into the base.”

As the convoy continued forward, the outline of the main city wall became increasingly clear, and its imposing grandeur and imposing presence created a stronger visual impact.

It was a giant city wall that was hundreds of meters high.

It is estimated to be 30 meters thick and is made of dark gray composite material. Its surface is so smooth and hard that no gaps can be seen. Under the sunlight, it gleams with a cold metallic luster, as if it were carved directly from the mountain, exuding an inviolable majesty.

The top of the city wall is paved with special anti-slip and wear-resistant paving stones, creating a circular passage that allows armored vehicles to drive freely. The edge of the passage is also equipped with a half-meter-high guardrail, which does not affect passage but ensures the safety of soldiers and vehicles.

On both sides of the passage, there is a watchtower every 20 meters.

The tower soars into the clouds, constructed entirely of alloy. The bottom layer houses a heavy ammunition depot, the middle layer contains large searchlights and radar equipment, and the top layer is equipped with twin-mounted anti-aircraft guns and anti-aircraft missile launchers. The dark muzzles of the guns point straight to the sky, exuding a formidable aura.

As Li Luo gazed at the impregnable city wall, his resolve to replicate the shield-type ability grew stronger.

While physical defenses created by metal-type abilities are reliable, they are ultimately limited. If they could be combined with the all-around protection of shield-type abilities, there would be an extra layer of solid protection, whether it's going deep into the heart of the zombie horde to carry out missions or escorting important supplies.

She had even begun to envision it in her mind:

If we could replicate the shield-type ability and reinforce it with our own metal-type ability, we might be able to create a composite shield that combines physical and energy defense. In that case, the safety of our team members during missions would be greatly improved.

"This city wall is made of materials that cannot be compared to ordinary ones."

Qin Fenglin's voice came at the right time, clearing up everyone's doubts, "It is constructed using a mixture of reinforced concrete and special carbon fiber, with multiple layers of alloy steel plates and energy conduction lines embedded inside. Let alone heavy weapons bombarding it, even a full-force attack from an 8th-level energy user would only leave a shallow crater on the wall, unable to break through its defenses. What's even more ingenious is that those energy conduction lines can absorb the energy of attacks and convert it into a defensive buff for the city wall. The stronger the attack, the more stable the defense becomes."
