They walked home through the lit streets slowly, not because either of them was tired — though Ye Mingzhu had now been awake for nearly twenty hours — but because Wei Liang was absorbing every light source they passed and neither of them felt like rushing.
Streetlamp. Convenience store sign. The warm glow of a still-open noodle restaurant, its paper lanterns swaying slightly in the autumn breeze outside the door. The cold blue wash of a television through a ground-floor window.
[Light Energy: 9/15... 10/15... 11/15...]
Ye Mingzhu walked with her hands in her pockets and said nothing for most of it. Wei Liang had come to understand that her silences were not empty — she was processing, the same careful turning-over she had done at the table this morning. He had learned in less than a day to leave her silences alone until she was done with them.
"Void Fragments," she said eventually.
"Yes."
"That's what the knowledge called them."
"That's what it called them." He paused. "I don't know where the knowledge came from. It arrived with the absorption — like it was stored in the core and transferred when I took it in."
Ye Mingzhu considered this. "So the entity itself knew what it was."
"In some sense. Or the residue of it did." He paused. "I'm not sure how much of what I absorbed was the entity's own awareness and how much was something more fundamental — like the information was simply part of what it was made of, the way the properties of a material are part of the material."
Ye Mingzhu nodded slowly. "And what it was made of told you there are more."
"Yes."
"Did it tell you where?"
"No. Only that they don't form in isolation — that the same conditions that produced one tend to produce others nearby. Dark enclosed spaces. Enough time." He thought about the neighborhood — the streets around the convenience store, the old buildings, the covered sections of the market. "This area has plenty of both."
They turned onto Ye Mingzhu's street. The apartment building was a narrow six-story block with a single light above the entrance, its bulb yellowing with age but steady.
[Light Energy +0.1]
Ye Mingzhu stopped at the entrance and looked up and down the street for a moment — not anxiously, just attentively, the way someone looked at a familiar thing they were seeing slightly differently than before.
"The underpass," she said.
"Which underpass?"
"Two streets over. On Qingyan Road." She paused. "The lights in it have been flickering for about two weeks. I walk through it on the way to the market sometimes. I thought it was just bad maintenance."
Wei Liang was still.
Two weeks. Longer than the alley.
"We should look at it," he said.
"Not tonight," Ye Mingzhu said. "You're not at full capacity and I haven't slept." She said it with the same practical flatness she applied to everything, not as an excuse but as a calculation. "Tomorrow."
Wei Liang could not argue with this. He was at eleven out of fifteen. The combat form required fifteen. Going into a potentially larger Void Fragment with no combat form and a wielder running on no sleep was not a plan, it was a problem.
"Tomorrow," he agreed.
She went inside.
Ye Mingzhu fell asleep almost immediately, still dressed, on top of the covers. Wei Liang, positioned on the desk under the lamp, watched her for a moment in the lamplight before turning his attention back to absorbing.
She had not hesitated in the alley.
He had told her to stand still and let the entity approach — to let something cold and light-devouring press itself against her chest while he prepared — and she had done it without argument, her pulse elevated but controlled, her breathing steady throughout.
He had been aware, in the moment, that this was not a normal response. Most people, presented with an invisible entity made of cold and absence rushing at them in a dark alley, would not stand still because a mirror asked them to.
Ye Mingzhu had.
He turned this over quietly while the lamp fed him light in slow increments and the city made its nighttime sounds outside the window.
[Light Energy: 12/15]
She had asked him, in the canteen, whether he had ever fought anything before. He had said no, and she had said that made two of them, and then had said okay and eaten her rice. As though the honest answer were sufficient. As though two people who had never fought anything being about to fight something were not a reason to reconsider.
He was not sure whether this was recklessness or trust.
He suspected it was neither. He suspected it was the particular pragmatism of someone who had been dealing with things alone for long enough that the addition of an uncertain ally still felt like an improvement over no ally at all.
[Light Energy: 13/15]
Wei Liang looked at her reflection in his own surface — the curve of her shoulder, the dark hair spread on the pillow, the composed quality her face kept even in sleep, as though even unconscious she had not fully put down whatever she was carrying.
He looked away.
He was a mirror. Observing was what he did. It was different from intruding.
He absorbed the lamp and thought about the underpass on Qingyan Road and what they would find there in the morning.
She was up before the alarm.
Six forty-three, alert immediately, sitting up and looking at the desk with the same expression as yesterday — the brief moment of recalibration as last night confirmed itself as real.
"Good morning," Wei Liang said.
"Good morning." She stood, looked down at her clothes, and registered that she had fallen asleep in them. A very brief expression crossed her face.
"You were tired," Wei Liang said.
"I know." She went to change.
[Light Energy: 15/15]
"I'm at capacity," Wei Liang said when she came back.
Ye Mingzhu paused in the middle of pulling her hair back. "Already?"
"I was absorbing all night." He paused. "The combat form is available if we need it."
She looked at him for a moment. "Before school or after?"
"Before, if possible. If the one in the underpass has been there two weeks, another day makes a difference." He paused. "But we should assess first. Look at it before we commit to anything."
"Assess and then decide."
"Yes."
She finished with her hair, picked up her bag, and placed him in the front pocket. "I'll take the Qingyan Road route to school."
The underpass on Qingyan Road was a pedestrian tunnel running under the elevated section of a rail line, about forty meters long, connecting the residential blocks on the north side to the market streets on the south. In the daytime it was used constantly — a shortcut that saved several minutes over the long way around, well-trafficked enough to feel ordinary despite its concrete walls and low ceiling.
At seven in the morning it was busy.
That was the first problem.
Wei Liang looked at it from inside Ye Mingzhu's pocket as she approached — the Reflective Eye cutting through the distance and the low light, reading the space.
The fluorescent strips along the ceiling were flickering. Not all of them, not constantly — just a rolling instability, the light stuttering at irregular intervals, some patches dimmer than others in ways that did not correspond to any obvious electrical issue.
And at the center of the underpass, in the densest section of the flicker, something that was not flickering at all.
A Void Fragment.
Larger than the one in the alley. Considerably larger — roughly twice the size, its formlessness more defined in the paradoxical way these things seemed to work, as though having more absence made the shape of it more coherent. It was pressed flat against the ceiling, spread across a section of the concrete above the highest fluorescent strip, and it was actively feeding, the light in the strips beneath it dimming and recovering in the stuttering rhythm he had observed.
People walked through it.
Not around it — through it. A man in a suit with a briefcase. A woman with two children, the smaller one in a stroller. Three high school students walking in a loose cluster, talking loudly. All of them passing directly under or through the spread of the entity without appearing to notice anything except, perhaps, a vague unease — a slightly quickened pace, eyes dropping, conversations momentarily quieting.
"There are people in there," Ye Mingzhu said quietly.
"I know."
"Is it hurting them?"
Wei Liang watched carefully. The people passing through did not stumble, did not stop, did not show anything beyond the subtle instinctive discomfort of moving through a space that felt wrong. No visible harm. But they were moving through the cold periphery of it, not its core — the densest part was pressed against the ceiling, feeding on the light source directly.
"Not immediately," he said. "But the longer it feeds the larger it gets, and the larger it gets the more of the underpass it occupies." He paused. "We cannot fight it here. Not with people present."
"Tonight then. After midnight."
"The underpass is gated at midnight. I passed one of the signs."
Ye Mingzhu was quiet for a moment. "Then we wait for the gap between the last pedestrians and the gate closing." She watched a cyclist pass through, pedaling slightly faster than necessary without seeming to know why. "That gives us maybe twenty minutes."
Wei Liang looked at the entity again, measuring its size against what he had faced last night.
Last night's Void Fragment had drained two points of light energy on a single pass and he had needed fifteen points to overload it. This one was twice the size. The same method might not be sufficient — or might require more than fifteen points, more than his current capacity.
"I need to be stronger than I was last night," he said.
"How much stronger?"
"I don't know yet. But I need to be at capacity and I need the capacity itself to be higher." He thought about the compact mirror sitting on the desk at fifteen out of fifteen, and the way each evolution had expanded his reserves. "I need to evolve again before tonight."
Ye Mingzhu thought about this. "What do you need to evolve?"
"More light. Different light. Last time it was the accumulated combination — moonlight, neon, lamplight, sunlight. The variety seemed to matter as much as the quantity." He paused. "I need light I haven't absorbed before."
Ye Mingzhu was quiet for one moment.
Then: "The roof of the school building faces east. Morning sun, unobstructed, from about seven thirty until the first class. I know because the astronomy club uses it." A pause. "And there's a photography lab on the third floor that uses specialized lighting equipment I've never seen anywhere else."
Wei Liang considered this.
"The roof first," he said. "Then the photography lab if the teacher allows it."
"I'll handle the teacher," Ye Mingzhu said.
She turned away from the underpass and continued toward school, the flickering light of the tunnel at her back, the morning sun ahead of her sharp and clean and full of things Wei Liang had not yet absorbed.
"Ye Mingzhu," he said.
"Yes."
"The people walking through the underpass this morning. The ones who came through the cold part — they'll be fine today. But we need to be done before they come back through tonight."
Ye Mingzhu's pace did not change. "I know," she said. "We will be."
She said it with the same simple certainty she applied to everything she had already decided, and Wei Liang found, not for the first time, that it was enough.
[Light Energy: 15/15]
The morning sun hit his surface as she rounded the corner out of the underpass's shadow, and he absorbed it hungrily, feeling the quality of it — sharp and cool and new, the particular clarity of autumn morning light.
[Light Energy +0.3... Light Energy +0.3...]
He was already over capacity.
[Evolution threshold approaching.]
Wei Liang went still with something that was not quite surprise.
Tonight was going to be different from last night.
He could already feel it.
