They left the apartment at nine fifteen.
Not because nine fifteen was a particularly significant time, but because that was when the last of the evening foot traffic thinned out and the street in front of the convenience store became quiet enough that a girl standing in front of a dark alley would not attract much attention.
Ye Mingzhu had eaten dinner — rice and egg and the last of a container of leftover vegetables — changed out of her uniform into dark, practical clothes, and stood in front of the bathroom mirror for a moment doing nothing in particular.
Wei Liang, sitting on the edge of the sink, did not ask what she was thinking.
Eventually she picked him up and put him in her jacket pocket.
"Ready," she said. It was not entirely clear whether she was saying it to him or to herself.
"Ready," Wei Liang confirmed anyway.
The street was quiet.
The convenience store was lit from within, its fluorescent glow spilling out onto the pavement the same as always, the night staff moving behind the counter in unhurried increments. A car passed. A man walked a small dog past the market entrance without looking up. Somewhere down the block a window was open and a television murmured.
Ordinary. Entirely ordinary.
Except the alley beside the convenience store, which was not ordinary at all.
Ye Mingzhu stood at the entrance and looked at it.
The darkness began at the first step in. Not gradually — immediately, absolutely, the same hard border as this morning but pushed even further out than before. Another half step closer than it had been at dawn.
The cold pressed outward from it like a slow exhale.
"It's grown again," Ye Mingzhu said quietly.
"I can feel it," Wei Liang said.
Even from her pocket the wrongness of it was tangible — a pulling sensation, but inverse, like the Devour ability running in reverse. Instead of light being drawn toward him, he could feel the light around the alley being drawn away, leaching steadily into the dark.
"Take me out," he said.
She held him up facing the alley.
He looked.
The Reflective Eye adjusted immediately, cutting through the dark the way it had this morning. The alley resolved into readable shapes — the same brick walls, the same drainage pipe, the same plastic crates.
The entity was no longer pressed into the far corner.
It had moved.
It was roughly in the center of the alley now, larger than this morning — not dramatically, but noticeably, the way a shadow grew when the light source moved closer. It was no longer dormant. It had no eyes that he could identify and yet the quality of its formlessness had shifted, become less passive, the way a sleeping animal was different from a still one.
It was awake.
And it had not yet noticed them, but it was the kind of awake that noticed things.
[Unknown Entity detected.]
[True-Sight active.]
[Entity has no reflective surface. Entity is actively feeding. Caution advised.]
"It's awake," Wei Liang said quietly. "And larger than this morning. It's in the middle of the alley now."
Ye Mingzhu's grip on him was steady. "Can it sense us?"
"Not yet. But if we stay here much longer it will." He paused, calculating quickly. "We need to transform before we go in. Once we're inside that darkness I don't know how much the cold will affect you without the combat form active."
"How do I transform?"
Wei Liang considered the new capability that had settled into place this afternoon, feeling for its edges, its mechanism.
"Hold me with both hands," he said. "And don't fight what happens."
Ye Mingzhu shifted to a two-handed grip, her palms warm on either side of his frame.
Wei Liang opened the Combat Form.
It was not a deliberate action exactly — more like releasing something that had been held in tension, a compression suddenly allowed to expand. Light flooded outward from his surface, not the brief flash of the contract formation but something sustained, purposeful, the stored light of an entire day of absorbing pouring outward and reshaping itself in the air.
It moved fast.
Light wrapped around Ye Mingzhu's hands first, then her arms, then spread across her shoulders and down, not burning — warm, precise, purposeful. It was not painful. Wei Liang could feel her surprise in the sudden tension of her grip but she did not pull away.
The light shaped itself into cloth — not cloth exactly, but something that looked like cloth and moved like cloth and was considerably more than cloth. A dress, deep silver-white, its fabric layered at the skirt and fitted close above, the collar high, the sleeves ending in close cuffs at the wrist. Along every edge a faint luminous pattern ran, repeating overlapping crescents that matched the etching on Wei Liang's frame.
Over the dress, at the shoulders and forearms and following the line of the collarbone, thin panels of something harder — not metal, but with the quality of it, carrying the sheen of polished mirror glass, light bending across their surface the way it bent across water.
Ye Mingzhu was no longer holding Wei Liang in her hands.
He was at her throat — a compact mirror on a thin silver chain, pressed against the base of her neck, warm and present and connected to her in a way that was different from being carried. He could feel what she felt now. The cold of the alley pressing against the edge of the transformed dress. The steadiness of her breathing. The acceleration of her pulse, carefully controlled.
She looked down at herself.
For a long moment she said nothing.
"...It's heavier than it looks," she said finally.
"The panels at the shoulders," Wei Liang said. "They're for protection. You'll stop noticing the weight once you're moving."
Another pause.
"It's quite — " She stopped.
"Quite what?"
"Luminous," she said. Not a complaint. Just an observation.
"We're going into a dark alley to fight something that eats light," Wei Liang said. "I don't think subtlety is the priority."
Ye Mingzhu looked at the alley.
"Fair," she said, and stepped into the dark.
The cold hit immediately.
Not the cold of winter air — something denser, more deliberate, the temperature of a space where warmth had been methodically removed. Wei Liang felt it through the connection with Ye Mingzhu, felt her body register it and push back against it, the Luminous Amplification working quietly to maintain her core temperature.
The dress emitted its own faint light, and that light held the darkness back — not far, only a meter or two in every direction, a small warm circle moving with them through the black. Beyond its edge the darkness was total.
Wei Liang guided her eyes.
"Straight ahead," he said quietly. "Ten meters. It's facing away from us right now."
Ye Mingzhu moved without sound. She was careful naturally — not trained caution, just the innate quietness of someone who had spent years not disturbing anyone.
Seven meters. Five.
The entity shifted.
Not toward them — just a general restless movement, the way something shifted in its sleep. But it brought one of its undefined edges closer to the circle of their light and Wei Liang felt the Devour ability flicker defensively, pulling inward.
"Stop," he said.
She stopped.
Three meters between them and the entity. Close enough that Wei Liang could see it clearly — the absence of form that was its form, the way it seemed to absorb not just light but the quality of space around it, making the air near it feel thinner, less real.
Then it turned.
Wei Liang did not know how something without eyes turned, but the quality of its attention shifted toward them with unmistakable directness, drawn by the light of the dress burning in the dark like a lamp in an empty room.
For one still moment nothing happened.
Then it moved.
It did not move the way physical things moved — no winding up, no transition from still to fast. One moment it was three meters away and the next it was simply closer, its undefined mass sweeping toward Ye Mingzhu with a cold that preceded it like a wave.
"Left!" Wei Liang said.
Ye Mingzhu was already moving.
She stepped left and the entity passed through the space where she had been standing, the cold of its passage so sharp that Wei Liang felt her breath catch. It pulled at the light of the dress as it went, visibly dimming the hem for a half second before the Luminous Amplification pushed back.
[Light Energy: 15/15 → 13/15]
Two points of light energy gone in a single pass.
"It drains on contact," Wei Liang said quickly. "Don't let it touch you directly."
"Noted." Ye Mingzhu's voice was even. She was watching the entity, tracking the quality of its formlessness the way Wei Liang was now, both of them reading the same absence of shape. "What do I do? I can't hit something that has no body."
The entity turned again, faster this time, the cold intensifying as it oriented toward the light.
Wei Liang thought quickly.
Twenty kilograms of telekinesis. Not enough to move the entity directly — he had no sense it had any physical mass to move. But the crates he had seen against the left wall —
He reached out with the telekinesis and found them immediately. Plastic, lightweight, stacked two high. He focused, gripped, and threw.
The top crate flew across the alley and passed through the entity.
Not into it — through it. Unimpeded, as if the entity were not there at all, the crate hitting the far wall with a hollow clatter and tumbling to the ground.
Physical objects went straight through.
"Physical force doesn't work," Wei Liang said.
"I could have guessed that," Ye Mingzhu said, stepping aside again as the entity swept toward her a second time. The hem of the dress dimmed at the near miss. [Light Energy: 12/15].
Wei Liang thought harder.
It ate light. It was drawn to light. Its entire existence was oriented around consuming it — and the combat form was radiating light in every direction, which was why it kept coming toward Ye Mingzhu rather than simply retreating to its corner.
What happened when something that ate light tried to eat too much light at once?
"I have an idea," Wei Liang said. "But it means letting it get close."
"How close."
"Very."
A pause. The entity circled the edge of their light, its formlessness rippling with something that might have been agitation.
"Tell me," Ye Mingzhu said.
"I think it can be overloaded," Wei Liang said. "It eats light, but it's small. Newly born. If I release everything I've stored directly into it all at once rather than letting it drain me slowly — it might be too much for it to process."
"You'd be emptying yourself completely."
"Yes."
"And if it doesn't work?"
"Then we're in a dark alley with no light and something that eats light," Wei Liang said. "Which is admittedly not ideal."
The entity rushed them again. Ye Mingzhu stepped aside and this time reached out and pushed at it with both hands — not a strike, just a test, her palms meeting no resistance whatsoever, passing through cold air that bit at her fingers instantly.
She pulled her hands back. The skin of her palms was reddened from the cold.
"Do it," she said.
"Stand still," Wei Liang said. "Let it come to you."
Ye Mingzhu stood still.
The entity oriented toward her immediately, drawn by the light of the dress. It moved toward her and this time she did not step aside and it hit the edge of the light circle and began to drain — the dress dimming, the cold spiking, Wei Liang feeling his energy dropping in fast increments.
[Light Energy: 10/15... 8/15... 6/15]
Now.
Wei Liang released everything.
Not in a direction — inward, a pulse, every point of stored light detonating outward from his surface simultaneously. The alley went white. Not the gentle luminescence of the combat form but something total, a burst of accumulated light from an entire day of absorbing — morning sun and lamplight and neon signs and incandescent bulbs and afternoon gold — all of it releasing at once into the entity that was pressed against Ye Mingzhu's chest trying to drink it in.
The cold vanished.
The darkness vanished.
For one full second the alley was brighter than noon.
Then the light died and the darkness came back and Wei Liang's energy was at zero and the alley was completely quiet.
Ye Mingzhu stood in the dark breathing steadily.
The combat form had gone out with the light. She was in her regular clothes again, Wei Liang a cold dark mirror in her hand, his surface completely dim.
"Did it work?" she asked.
Wei Liang looked.
The Reflective Eye still functioned — it ran on something other than the stored light, something more fundamental. He looked into the darkness at the spot where the entity had been.
The formlessness was gone.
In its place, on the ground at the far end of the alley, something small glinted faintly. Round. About the size of a coin.
"It worked," he said.
Ye Mingzhu let out a slow breath.
She walked to the far end of the alley — carefully, her eyes adjusting to the returning darkness — and crouched down. She picked up the small round object and held it toward the distant light of the street.
A small sphere. Perfectly round, perfectly smooth, dark in color but with a faint inner luminescence, the way a coal carried a glow long after the fire had left it.
"What is this?" she asked.
Wei Liang looked at it.
[Residual Light Core detected.]
[A condensed remnant of an entity that absorbed light. Contains compressed light energy and a trace of the entity's nature. Can be absorbed.]
"It's what's left of it," he said slowly. "After it was overloaded." He paused. "I think I can absorb it."
"Will that tell you what it was?"
"I don't know. Possibly." He paused. "Hold it against my surface."
Ye Mingzhu pressed the small sphere flat against Wei Liang's face.
The Devour ability engaged immediately — hungry, fast, pulling the sphere inward in a single smooth motion. The compressed light hit Wei Liang's empty reserves like water into a dry vessel.
[Light Energy +8]
[Residual nature absorbed.]
[Entity classification updating...]
A pause. Then:
[Entity Classification: Void Fragment — a minor entity formed from accumulated absence of light in a sealed space. Feeds passively on ambient light. Grows proportionally to feeding duration. Weakness: light saturation.]
[New knowledge acquired: Void Fragments are not solitary. Where one forms, others follow.]
Wei Liang was very still.
"What is it?" Ye Mingzhu asked. She had felt the pause through the contract.
"It has a name now," Wei Liang said. "A Void Fragment. A minor one — newly formed, as I thought." He paused. "And I know how they form, and what their weakness is." Another pause, longer. "And I know that they don't appear alone."
The alley around them was dark and cold and completely quiet.
Ye Mingzhu looked at it. At the empty corner where the entity had been. At the ordinary brick walls and the drainage pipe and the plastic crates scattered across the ground.
"There are more," she said.
"Not here," Wei Liang said. "Not yet. But somewhere in this neighborhood. The same conditions that let this one form — a dark enclosed space, enough time, enough absence." He paused. "This one had been here eleven days. Others could already be older."
[Light Energy: 8/15]
The combat form was offline. He would need to absorb before he could unlock it again.
Ye Mingzhu straightened up and looked at the alley entrance, at the streetlamp burning steadily beyond it, the orange light now reaching all the way to the back wall for the first time in eleven days.
"We should find them," she said.
"Yes," Wei Liang said. "We should."
She walked out of the alley and back into the light, and the cold at her back was just the ordinary cold of a night in early autumn, and for the first time in eleven days the back alley of the convenience store on Fenglin Road was simply an alley again.
Wei Liang absorbed the streetlamp as they passed it.
[Light Energy: 9/15]
It was a start.
