With a crisp sound like metal clashing against stone, the bone spike was deflected by the longsword and embedded diagonally into the rock wall.

Before Alice’s incredulous gaze, a knight in black armor emerged from the darkness, walked past her, and blocked the undead’s path.

The first bone spike shrieked as it lunged at the knight.

Before it even hit the ground, the knight's azure longsword sliced ​​it in two from head to tail at a speed invisible to the naked eye.

The second bone spike crouched in place, shook its body, and shot the bone spikes on its back toward the knight.

The knight advanced slowly, his black armor transforming into sharp limbs, which swiftly knocked down the bone spikes in mid-air one by one.

The knight calmly walked up to the second bone spike undead, swung his longsword, and decapitated the attacker.

The third bone-spiked undead, facing the knight, actually began to slowly retreat.

Without giving the opponent a chance to turn and run, the knight picked up a bone spike from the ground and threw it forcefully.

The bone spike pierced the back of the third undead's head, pinning it firmly to the rock wall.

This lightning-fast battle, lasting only a few seconds from start to finish, left Alice so shocked that she questioned the meaning of life.

After dealing with the three undead, the knight sheathed his sword, stepped over Alice on the ground, and slowly walked into the depths of the passage.

Alice glanced at the remains of the undead on the ground, then looked at the dark passage. She made up her mind, got up from the ground, and followed the knight step by step, slowly walking into the depths.

After walking for an unknown amount of time, Alice was surprised to find that the numbers on the radiation counter were almost normal, and the passage was getting wider and wider, with many traces of artificial construction on both sides.

Following the knight through a massive stone gate, Alice found herself in a vast, boundless hall.

Stone pillars carved with dragon patterns, floor tiles paved with blue slabs, and wires emitting a pale blue light all add a touch of science fiction to this medieval retro-style hall.

On a high platform deep within the hall, a group of tall women carrying bows and arrows stared intently at Alice, occasionally arguing heatedly among themselves.

Alice hesitated as she watched the knight continue on his way.

Faced with all this unknown, a thought of retreat arose deep within her.

However, upon returning to the ground, the intense radiation, the dangerous hordes of zombies, the lack of food, water, and vehicles, coupled with her leg injury, meant that her chances of survival were undoubtedly close to zero.

Left with no other choice, Alice could only continue following them.

The knight passed through a wide underground corridor.

The corridor is lined with many exquisite murals depicting birth, struggle, death, redemption, and more, telling a long-forgotten story and an ancient legend.

Alice looked at the mural and felt a strange feeling growing stronger.

The knight finally arrived at a huge, empty underground plaza.

As soon as Alice entered, she was so terrified by the sight before her that she forgot to move.

Thousands of knights clad in black armor knelt on one knee in the square, their heads facing forward.

The knight who had saved Alice walked into the crowd, found his place, held his longsword in both hands, knelt on one knee, and remained motionless like a stone statue.

The air was so quiet that Alice couldn't hear a sound of the wind, not even the sound of her own heartbeat.

Alice wanted to turn and leave, but a voice kept telling her to keep moving forward.

After passing through the ranks of knights, Alice finally arrived at the deepest part of the square.

Standing on the cliff at the edge of the square, Alice looked down.

Below the unfathomable depths lies a clear and shimmering "lake".

The pale blue "lake water" is without ripples or waves; it looks like countless floating pale blue particles gathered together, beautiful and mysterious.

Gazing at the pale blue "lake," Alice vaguely saw a huge shadow emerging from the "bottom of the lake."

A pair of golden dragon eyes slowly approached the woman.

A familiar and warm voice echoed in her ears.

"We once made a promise..."

(The End)
