In the illusion, the little blonde girl wore a brilliant smile, somewhat clumsily holding colorful crayons, scribbling and painting in a book. Her seated posture was skewed and awkward, and next to the pile of toys behind her, there were two metallic children's crutches.

The blonde woman sitting beside her gazed at the little girl silently, with eyes full of tenderness, pity, and sorrow. She gently reached out her hand to stroke the girl's soft hair.

"Mommy, look what I drew?"

The girl lifted the book, on which two pink human figures, a large one and a small one, both wearing ballet tutus and striking dance poses, were drawn. She covered half her chubby face with the book and looked at her mother with her big, watery eyes, coquettishly saying, "Mommy, when I get better, you have to teach me to dance."

A trace of unnoticeable sadness flashed across the woman's eyes. She blinked and revealed a faint smile, embraced her daughter, and kissed her forehead, "...Of course, Alice."

The illusion ended there, and as the mist slowly dissipated, the room returned to its decayed and broken state.

"Is it over?"

Li Ang furrowed his brows, glanced at the note in his hand, and muttered, "Hmm... it seems Alice had polio, and for some reason, her parents could no longer take care of her. Did the parents go somewhere far away? Or did they notice something odd about the house and were planning to send Alice away?"

As he was deep in thought, a flurry of footsteps suddenly echoed from above the ceiling.

TAP TAP, TAP, TAP TAP, TAP.

The footsteps were rhythmic, and judging by the direction of the sound, it seemed as if the owner of the footsteps was bouncing back and forth on the floor above, tracing circles?

Li Ang silently switched off his flashlight, took out the Triangular Bone Tipped Spear, held it in his hand, and aimed the sharp end of the spear toward the source of the footsteps, following the invisible figure in its circular path.

Suddenly, the noise ceased, and all was quiet. Li Ang silently bent down, propped himself up with the spear, and indifferently looked upwards.

"CREAK—"

A square wooden door set in the ceiling was slowly opened, revealing a dark passage to the room above.

In the moonlight, fine dust could be distinctly seen drifting down from the room above.

In the deadly silence, a little leg clad in a dirty ballet shoe and white tights covered in dust stretched out from the narrow wooden doorway, slowly resting on the edge of the door.

Then came another leg.

With Li Ang's sharp insight, he easily discerned that these legs did not belong to any of his teammates. He had observed the other players' heights, weights, and body shapes through scanning them earlier when all five were still in front of the villa.

These legs, though not as long as Forest Cat's, had superior curves.

Comparable to a statue, possessing great aesthetic beauty. Exquisite.

Person? Or monster?

Li Ang, hidden in the dark, held his breath, concentrated, and concealed his presence, silently watching the little legs dangling from the ceiling swing back and forth like a pendulum.

After a moment, as if finally making up their mind, the legs slowly inched forward and suddenly jumped down from the wooden door.

THUD.

The legs landed on the floor of the room, almost losing balance, and after some effort, managed to stand firm again.

With the help of the moonlight, Li Ang could fully see the figure.

Indeed, it was a pair of legs in ballet shoes and tights with a skirt, but the body above the pelvis had vanished, leaving only two slender arms suspended above the legs. The skin around the palms of those arms appeared much dirtier than other areas; a mixture of dust and bloody scabs from wounds that had torn and re-healed gave them a grim, reddish-black hue.

Without a torso, only limbs, the "ballet dancer" continued her ballet dance movements with utmost clumsiness in the room. Being eyeless, she often collided with furniture and objects, falling to the ground, appearing pitiful and devoid of any threat.

Above the elbow of her left arm, there's a mole... Just like Alice's mother in the illusion. And her current state, having only limbs and no torso, likely corresponds to the 'limbs' marked as an abnormal organ in the mission objectives.

Li Ang did not attack her. Instead, he huddled against the wall, watching her tiptoe, clumsily dancing, slowly moving to the center of the room.

Then, she made a rough 'bending over' motion, stooping to kneel on the ground and grope about with her hands. It seemed she was searching for something.

Li Ang's thoughts stirred, his fingertips gently rubbing on the note written for Alice. After pondering for a moment, he extended his spear, lightly flipping through the pile of debris on the floor with the blade, and found the fairy tale book that was identical to the one in the illusion. With a flick of the blade, he tossed it steadily half a meter in front of her.

Soon, the limb-only non-human creature found the fairy tale book. She picked up the book with trembling hands, turned to a page with drawings, knelt on the ground, curled up, her hands and feet slowly losing color and petrifying into a statue.

"Is that it?"

Li Ang was taken aback for a moment, walked forward, and prodded the thoroughly petrified delicate arms and legs, weighing them a few times, only to find that they were extremely heavy and strong, comparable to the Bonetip Spear's body.

He squinted, rubbed his chin with his palm, and waved the stony leg.

"Wait, I think I might have a bold idea."

[Abnormal limbs cleared. Seven types of abnormal organs remaining.]

The System announcement didn't just ring in Li Ang's ears; his teammates heard it too.

At that moment, Stonemason was standing in a spacious and well-lit room. The room's doors and windows were shut tight. Thick curtains left no gap for air, and several wall lamps emitted light, illuminating the rows of shelves that almost filled the room.

"One has been resolved so quickly," Stonemason nodded to himself and muttered, "Too bad, I don't know who solved it."

He took out two ordinary plastic utility knives, held them in his hands, and, carefully cautious, approached the shelves, inspecting them closely. "Is this a storage room?"

The shelves were not decked with ceramic tableware or antique relics, but with odd items such as spider specimens, dried lizards, wild boar skulls, and Glass Bottles containing an unknown dark green viscous fluid, and even some glass jars with deformed unborn lambs soaked in formalin.

It was hard to imagine that the luxurious and refined manor had anything to do with the bizarre items on the shelves.

"Witchcraft... perhaps?" Stonemason scanned the shelves, murmuring to himself.

His knowledge of mysticism was decent. The items stored here were all alchemical tools used in witchcraft.

"The owner of Williams Manor, a wizard? Or going further, the family that owns this estate, are they a lineage of witchcraft... This would explain why this manor is so strange," he muttered to himself, his gaze sweeping across a row of shelves. Suddenly, he stopped in his tracks and stared intently at a glass jar.

It was filled with a pale yellow transparent liquid, and a beating human heart was floating within it.

Beneath the glass jar was a label: Mr. Williams's heart specimen, 10, 8, 1830.

Stonemason stared at the throbbing heart, his own breathing growing more rapid. He could feel that as Mr. Williams's heart grew more vigorous, his own heart was slowly shrinking, heading towards arrest.
