The black marble, hidden in the night, traced a precise arc and landed steadily in a relatively open area with few zombies.

"Bang!"

A distinct sound ripped through the air, and the black marble exploded on the spot. It had no harmful effect, but instead burst into a dazzling light, instantly illuminating the surroundings.

The sudden light was like daylight appearing out of nowhere, causing the previously restless corpses to instantly show fear and take two steps back. But then, they seemed to be enraged by this unknown power and swarmed towards the source of the light and sound like madmen.

Seeing this, Chuanliu quickly threw the rope he had prepared to the team that was still struggling to climb.

The rope fell in front of the leader and swung to another building not far from them.

After the initial shock, the captain quickly recovered and looked along the other end of the rope, where he saw a human girl standing on the roof.

The girl's hair was as black as ink, casually draped over her shoulders, partially obscuring her face and making her appear mysterious and unpredictable.

The moonlight bathed her in a silvery glow, making her expressionless face appear even more aloof. A gentle evening breeze, carrying a hint of coolness, lightly ruffled her sleeves, making her seem like a ghost emerging from the midnight sky.

The girl simply looked at them quietly and gestured for them to be quiet.

With the corpses before them, they had no time to consider why this girl had appeared there.

The captain was overjoyed and immediately lowered his voice to relay the instructions to his teammates: "Climb up the rope! Quickly!"

Upon hearing this, the other seven team members also looked up at the life-saving rope, a glimmer of hope shining through their despair.

They made no sound, but climbed even harder.

To ensure the zombies' attention remained focused, Chuanliu fired two more flashbangs in quick succession.

Flashbangs exploded in different directions, diverting the zombies' attention away from the group and buying everyone precious time to relocate.

When the horde of corpses lost the guidance of the flashing light and refocused on the previous floor, the eight people had already struggled to climb to the edge of the roof.

The corpses roared in resentment, and just as Chuanliu had predicted, they began to try to stack their bodies together, attempting to grab them in this primitive way.

The eight people quickly gathered on the rooftop where Chuanliu was located; time did not allow them to ask too many questions.

At the entrance to the rooftop, a heavy wooden door was firmly nailed shut, becoming an obstacle for them to go downstairs.

The squad leader spoke first: "Once we're inside the building, they won't bother us as long as they can't find us!"

Having said that, he immediately took action.

He strode forward, gripping a gleaming iron sword tightly in both hands. The tip of the sword was plunged deep into the cracks in the wooden planks. Then came a series of decisive and powerful movements: prying, smashing, and tearing. Each forceful movement was accompanied by a loud "bang" as the planks shattered, like the rapid and powerful drumbeats of war.

Amidst the flying sawdust, the wooden planks gradually crumbled, revealing the outline of the tightly closed door behind them.

Upon seeing this, one of the team members rushed forward, gripped the doorknob tightly with both hands, and twisted it sharply, only to receive a cold response—the door was locked from the inside.

Then he brought over a few more people, and they all rammed the door at the same time, but the metal door didn't budge.

He turned around, his eyes filled with anxiety and helplessness, and everyone's faces darkened as well.

"what to do?"

These three simple words struck everyone's heart like a heavy hammer, causing cold sweat to gather and drip from their foreheads.

Are they all going to perish here?

Downstairs, the pile of corpses had reached halfway up the building, and they were letting out even more frantic roars, as if the entire building was shaking with the cries of these creatures.

At this moment, the girl who had been silent spoke up, "Excuse me, let me do it."

Her voice was soft, yet it inexplicably brought a sense of peace to everyone present.

"You're just a young girl, don't bother joining in the fun. Even with so many of us, we can't open it..."

The team member pulling the door was anxiously trying to stop her, his body already unconsciously preparing to try to ram the door again.

However, their captain grabbed him and said, "Let her try."

Chuanliu nodded to the captain and took out a very ordinary hair clip from his hair.

With practiced ease, she carefully inserted the barbed wire into the keyhole of the iron door. Then, with a gentle twist of her fingers, the wire seemed to come alive, moving nimbly within the keyhole.

"Can this work...?" The team member looked at the girl's actions with a doubtful expression, glancing around anxiously.

In an instant, a hideous corpse leaped onto the rooftop. Upon seeing the group, it let out a deafening roar, its eyes gleaming with bloodlust.

The squad leader reacted swiftly, raising his longsword to meet the attack and engaging the zombie in fierce combat. The other team members followed closely behind, their swords flashing like a tapestry, instantly plunging several blades deep into the zombie's body.

However, the corpse seemed to ignore the pain. Despite its body twisting and struggling under the sword, it miraculously stood up from the ground again. Blood continued to flow, but it still attacked with all its might, and its speed was astonishing.

Damn it!

The captain cursed angrily, and was about to launch another fierce attack.

At this moment, the girl who had been silently unlocking the door spoke again, her voice calm and clear: "Attack the heart or cut off the head."

Upon hearing this, a resolute glint flashed in the captain's eyes. He concentrated all his strength, and his longsword swung in a sharp arc, striking the corpse man's neck with pinpoint accuracy.

With a dull thud, the corpse's head rolled to the side, and its body ceased its struggle.

However, the crisis was not over. More zombies seemed to be summoned, leaping from the ground floor onto the rooftop one after another, surrounding everyone.

Just as everyone was preparing to meet this new wave of attacks, they suddenly heard a "crack".

The girl stood up and quickly said, "It's open."

At this moment, her voice, like heavenly music, brought a turning point to the siege.

The girl opened the door first and entered, followed by the squad leader who escorted his team members in one by one. Holding a long sword, he stood behind the group, and before the zombie could react, he quickly turned around and, taking advantage of the brief opening, slammed the door shut with a loud bang.

Outside the door, the corpses surged in like a tide, frantically tearing at the heavy iron door.

The captain issued a firm command: "Quick! Find somewhere to hide!"

With his extensive experience, the captain quickly located a windowless room and directed everyone to hide inside, keeping the outside dangers at bay.

The atmosphere inside the sealed room was heavy.

Faintly, the sound of shattering glass could be heard coming from the second and third floors, indicating that the corpses had begun to break through the windows.

Immediately afterwards, heavy, dragging footsteps came from downstairs, each step pressing closer, making one's heart tighten.

Everyone gripped their iron swords tightly, the tense atmosphere almost freezing the air.

The captain looked at Chuanliu, said nothing, and tossed her a short knife from his waist for self-defense.
