From the shoulder of rock, the mountain looked like a single living thing, and it had begun to change.
Lin Tianren had climbed up to read the terrain, and the terrain read back something he hadn't expected. In certain stretches of the valleys below, spiritual energy lay thicker than it should have, pooled in hollows the way water pools after rain, so dense that the mist there glowed faintly even in full daylight. Herb patches he had noted from the ridge an hour earlier had simply vanished, the slopes where they'd grown stripped down to bare soil and trampled stems. And far across the opposite ridges, flashes of spiritual energy kept breaking out and dying away: two, three in quick succession, a longer one, then silence, then another somewhere else entirely.
*System. Why is the energy gathering in those hollows?*
**[Cause: Undetermined]**
**[Natural Variation Within Expected Range: Unconfirmed]**
He didn't press it. He had stopped expecting the system to settle every question the mountain asked, and had begun treating its silences as information of a different kind. Whatever was happening with the energy, he could only describe it, not explain it.
What he could explain was the rest. Every participant carried a Golden Spirit Vessel heavy with whatever they'd gathered, which meant every participant was a hunter and a target at once, and the stripped herb patches meant someone was harvesting faster than the mountain could regrow. The distant fighting meant the alliances he'd seen forming on the first day were already colliding with one another. The sect had placed a hundred and fifty people in a mountain with one rule that mattered, and the longer he watched, the clearer it became that the tournament was measuring something wider than alchemy. Survival instincts, certainly. Judgment, and whether a person could read a situation before it read them. Who would choose to stand beside whom.
Whether it was measuring anything beyond that, he had no evidence to say. He noted the possibility and set it down, the way he'd learned to handle most things that arrived without proof.

His own reserves were a quieter problem. The fox, the hound, and the egg still drew on his spiritual energy with every passing hour, steady as a tide, and he had no pills to refill what they took. Everything he'd refined had been left behind at the gate, as the rules required. He had the cluster of Azure Spirit Grass sealed in the vessel, and its stabilizing properties would help once he found the time to refine something from it, but he wasn't willing to spend it on himself yet. It was too valuable, and too strange.
*Rest, then,* he thought. *Cultivate when it's safe. And find people who can watch my back while I do.*
The thought carried him back to the decision he'd made that morning. He had both participant numbers, 123 and 130, but numbers told him nothing about where two people had landed in a mountain this size. He studied the land instead, reading the shape of it the way he'd once read quarterly reports for patterns the authors hadn't intended to show. Ridgelines that funneled travelers toward passes. River valleys that drew everyone sooner or later, because every participant needed water. Dense patches of forest where someone could hide for days. The faint scars of spiritual disturbance where people had fought, and, perhaps, where people had moved away from a fight.
Gu Chen would be wherever the ground was hardest to cross, because that was the kind of person he was: reliable in combat, stubborn about holding a line, the sort who walked toward difficulty rather than around it. Xia Qing would be somewhere the energy behaved strangely, because she noticed such things before anyone else did and couldn't leave them alone. If they were both alive, he thought, they would be moving toward the places that suited them. He gave himself no guarantee that he would find either of them.
It wasn't a flashback he indulged in, only a clear recognition: he wanted them alive. That mattered more than the tactical case for finding them.
---
By midday, he had worked his way down into a ravine where the forest thinned around a small clearing, and the clearing stopped him before he'd fully entered it.
Herbs grew there in a neat, valuable cluster, three varieties he recognized and one he didn't, all of them good enough to justify a detour. Too neat, though. The surrounding vegetation lay trampled and disturbed in a ring, while the herbs sat undisturbed at the center, as though something had cleared the ground around them to make them easier to see.
He crouched at the treeline and didn't step out. Footprints led toward the clearing from only one direction, deep and clear, and the more he studied them the more deliberate they looked, pressed into the soil by someone who had wanted them found. A faint disturbance clung to the air above the herbs, the kind a person leaves when they've been standing still for a long time and trying not to be felt.
He recognized the design because he had built something similar himself, on the first day, with a handful of ordinary herbs and a second participant's careless greed. This was a better version of the same idea, with valuable bait instead of worthless bait, and it would catch anyone who reached for it without looking first.
He picked up a small stone and tossed it into the far side of the clearing, where it struck a rock with a sharp crack.
Two participants burst from concealment almost at once, one from a hollow beneath a fallen trunk, the other from a thicket on the clearing's opposite side. They moved toward the noise with the quick, practiced coordination of people who had rehearsed this, spreading wide, weapons half drawn.
Lin Tianren did not fight them. He counted instead: where each of them had hidden, how quickly they emerged, which direction each had checked first, and which route each would have used to withdraw if the ambush failed. By the time they realized the stone had been bait of his own, they had drifted well away from the herbs and the clearing's only direct exit.
He slipped out along a different line, through a gap in the undergrowth the two ambushers had left unwatched, and was a hundred meters away before either of them thought to look behind. He took none of the herbs. A man who steals bait is only a different kind of trapped.
*I don't have to win every fight,* he thought, moving quietly through the ravine. *Most of the time, I just have to be the one who isn't there when it starts.*
---
He was still putting distance between himself and the clearing when something on a rock face beside the path caught his eye and stopped him cold.
A black-gold mark, small and half erased.
It sat low on a slab of gray stone, the same color and the same strange metallic sheen as the pattern in the cave the night before. But this one was nearly gone, only a fragment remaining, as though someone had scraped most of it away with something sharp. Fresh scratches ran across the surface around what survived. It had been erased deliberately.
He crouched beside it and studied the fragment carefully. The curve at its edge matched a curve he'd seen in the repair marks at Moonfall, though he couldn't have said whether it matched the same *hand*.
**[Residual Pattern Detected]**
**[Comparison With Previously Recorded Material: Inconclusive]**
**[Possible Causes: Environmental Degradation / Deliberate Interference / Incomplete Structure]**
He looked at the scratches again. Environmental degradation didn't cut straight lines.
*The same material,* he thought. *The same pattern, or close enough to it. And now it's appearing in the middle of a tournament that isn't supposed to have anything to do with Moonfall.*
Two possibilities followed from that, and neither was comfortable. Someone had carried it into this mountain with them, or the mountain had been connected to it long before the tournament began.
He didn't have enough to choose between them. He left the mark where it was, committed the fragment's curve to memory beside the pattern from the cave, and straightened slowly.
---
He had taken only a few steps further when a faint spiritual fluctuation reached him from a rocky slope to the east, so weak he nearly missed it, and so strange that he stopped to listen for it again.
It felt familiar. He couldn't have named it, only that it brushed against something in his memory the way a half-remembered voice does, and he was too wary of the mountain's illusions to trust his own sense of recognition without something to check it against.
He followed it anyway, carefully, up the slope to the mouth of a narrow passage between two cliffs. Broken stone lay scattered across the ground at its entrance, and beyond it the remains of a formation sprawled along the walls, its lines fractured and partly collapsed.
It was a strange design, and he understood very little of it. He remembered Xia Qing telling him that some ancient formations couldn't be repaired without first understanding their original structure, and that you read that structure in the damage as much as in the lines that survived. He stood at the entrance, trying to read what the damage was telling him, when voices drifted up from somewhere inside.
"The formation was already broken when we got here," one said. "I'm telling you, somebody came through before us."
"Then stop wasting time," said a second voice, sharper, tired. "If we don't find the herb before sunset, we're finished."
He didn't recognize either of them. He stayed absolutely still. Three choices presented themselves: go in and risk meeting whoever was inside, wait for them to leave, or examine the area first. Going in blind was the kind of decision that had cost people their lives in this mountain already. Waiting meant giving the voices time to find him.
He chose the third. It matched everything he'd learned about himself since Moonfall.
---
He circled the passage's entrance without entering it, studying the formation's broken edges, and stopped at one section that didn't match the rest.
It was small, a few lines near the base, worked in a different hand from the structure around it. Its looping closing stroke curled back on itself in a way he'd seen before, traced with a fingertip along Moonfall's wall by someone whose voice had stayed steady even while her hands shook.
It wasn't Gu Chen's work. Gu Chen fought with a sword and a stubborn heart, not a brush. This looked like Xia Qing's craft, or the family tradition she'd learned it from, which was exactly the problem. She had told him herself that the technique behind Moonfall's repair resembled her own family's. The same stroke, he realized with a faint chill, could belong to her, or to anyone who had learned from the same source.
System offered nothing, and he hadn't expected it to. He raised a hand toward the damaged edge, then stopped an inch from the stone without touching it.
*If Xia Qing passed through here,* he thought, *she might have noticed the same thing I just did.*
*And if someone else left this...*
*Then I need to know why.*
A heavy impact echoed out of the passage before the thought could finish, stone shuddering under a blow. Silence followed, long enough for a breath, long enough for him to feel his own heartbeat.
Then a voice, clear and close, from just inside the dark.
"Who's there?"
Lin Tianren was already moving, shifting his weight into the shadow of the cliff before the last word had finished echoing.
