Wuming Demon Mountain lay under a hush so heavy it felt like a hand over the mouth of the world. Hua Ruoying stood outside Hua Qiuyuan's door, unmoving, as though the wood itself could sense her hesitation and had learned to hold its breath with her.
Qingping came trotting up the corridor, relief bright in his eyes. "Ruoying sister—there you are."
Warmed by habit, Hua Ruoying answered with a gentleness that didn't quite reach her gaze. "Weren't you supposed to wait for me in the room? Why are you out here again?"
"You said you'd be right back." Qingping's voice softened. "But you didn't come back for a long time, so I went looking for you."
He followed her line of sight and noticed the hibiscus-colored bottle clenched in her hand so tightly her knuckles had gone pale.
"Ruoying sister," he asked carefully, "what are you doing here?"
Hua Ruoying didn't respond at first. Her eyes stayed on the door, as if she were waiting for it to open on its own. Then she looked down at the bottle, lips pressing together, and only after that did she speak.
"It's my brother's room."
Qingping blinked. "Then why don't you go in? Is he not inside?"
Inside the room, Hua Qiuyuan had already sensed her presence—had sensed it long before Qingping's footsteps arrived. He sat without moving, the familiar stillness of a soldier who had learned how to lock everything away, even breath, even pain.
And yet memory, unbidden and sharp as a blade, pried its way through the cracks.
Years ago, when hunger had hollowed them out and cold had taken turns chewing at their bones, he and Ruoying were brought to Wuming Demon Mountain by the Demon Lord. Back then, he'd expected cruelty. He'd expected the demon realm to be a furnace that burned soft things into ash.
Instead, Fanli Valley had been strangely orderly. The demon soldiers did not revel in abuse. The people lived their quiet lives under the mountain's shadow, and if the sky was darker, if the wind carried a different taste, it still could have passed—almost—as peace.
Qiuyuan had been trained because he was useful. Ruoying had flourished because she had a gift and the mountain had no shortage of poisons that could be turned into cures. They had lived, for a time, like two strays who'd found a warm corner and dared to believe it might last.
Until the Demon Lord emerged from seclusion as if he'd shed something human-shaped and put on something colder.
That day, the Demon Lord had toyed with a blue pill between his fingers, turning it so the light caught its surface.
"This pill," he said, voice smooth as a knife sliding from its sheath, "you may choose whether you or your sister takes it."
Qiuyuan had not hesitated. He swallowed it straight from the Demon Lord's hand.
The cold hit like a flood. His body temperature fell in an instant, as if someone had shattered a winter sky inside his veins. He crumpled to the floor, curling in on himself as frost crept over his limbs, whitening his skin in patches where the chill bit deepest.
He couldn't speak. He couldn't even properly breathe.
The Demon Lord watched him with an expressionless patience.
"That was decisive," he remarked, unimpressed. "I thought a demon soldier leader would be more cautious about swallowing an unknown pill."
Qiuyuan had tried to lift his head, eyes wide, confusion and fury and helplessness colliding in his throat.
The Demon Lord leaned closer and pinched his face, almost intimate. "The other pill," he said, "I gave to your poison-loving sister. I wonder if she has taken it yet."
Qiuyuan's gaze had snapped up, rage struggling against paralysis.
"Don't worry," the Demon Lord continued, and his tone turned almost indulgent. "The pill she took won't harm her—for now."
He released Qiuyuan's face with a careless flick, like discarding something that no longer entertained him.
"I simply despise seeing the bond between siblings," he said, and the words carried a quiet relish. "The deeper you cling to each other, the more I want to pull you apart."
Qiuyuan had forced air into his lungs, coughing hard enough to taste blood.
The Demon Lord lifted two fingers and snapped them lightly through the air. The frost on Qiuyuan's limbs halted mid-bloom, as if the cold had been ordered to pause.
"The poison won't activate easily," the Demon Lord said, already turning away. "But it will flare whenever you draw near that little wretch. So stay where you are if you don't want to suffer. Every. Single. Time."
Since then, Qiuyuan had tested the boundary in small, desperate acts—one step, then two, then three—only to have the cold surge through him the moment he got too close. And Ruoying had learned the same lesson from the opposite side: the warmth in her own body would spike, answering his poison like a cruel echo, ensuring neither of them could pretend it was only his burden.
Now, behind the door, Qiuyuan felt it again.
A faint creep of frost along his fingers.
He didn't move. He didn't make a sound.
Outside, Hua Ruoying's grip tightened around the hibiscus bottle. She took an instinctive step forward—so small it barely counted as movement at all.
And still the heat inside her flickered awake.
Inside the room, Qiuyuan's hand stiffened, the chill biting deeper, familiar and sharp. He inhaled slowly through his nose, forcing the reaction down, forcing his body into obedience.
Hua Ruoying felt it too—felt the wrongness in her blood—and immediately stepped back, as if the distance between her and the door were a line she'd learned not to cross.
Qingping noticed the sudden retreat and frowned. "Ruoying sister… what's wrong?"
"It's nothing." Her voice came too quickly. Too smooth. She didn't look at him. Her eyes stayed fixed on the door as if it were a person she couldn't face.
Then she turned the bottle in her hand, considering it like a decision made physical.
"Qingping," she said, and her tone softened by force, "Can you doop this pill by the door?"
Qingping took the bottle obediently. "Oh. Okay."
He crouched and set it down carefully, as though afraid even the stone floor might crack under the weight of her unspoken worry.
For a moment, Hua Ruoying stood there, hands empty, feeling the absence of the bottle like a phantom ache. The corridor remained silent. The door remained closed.
Inside, Qiuyuan stared at the shadow under the door, his jaw set so tight it threatened to split.
Outside, Hua Ruoying turned away before she could be tempted into another step.
And far from the demon mountain's hush, the Liao Yin Immortal Realm churned with rare bustle—lanterns being hung, invitations delivered, ceremonial lists rewritten and checked again—as the birthday of Celestial Master Situ Fanzhi drew near and the entire realm moved like a river toward celebration.
