Chapter 5: The Crystal Rules
"What exactly are you thinking?"
Renyu back stiffened.
Qian Renxue hand was still resting on his head, light and almost idle, but there was nothing idle about her gaze. She had asked the question in Xue Qinghe voice, calm and elegant and impossible to evade, yet Renyu could feel the woman beneath the mask watching him far too closely.
He swallowed once.
"Nothing important."
Her brows rose.
That alone told him he had answered badly.
"Nothing important," she repeated. "Immediately after awakening a martial spirit that accepts any spirit ring, comes with fixed skill paths, and gave you full innate soul power."
When she laid it out like that, even he had to admit the timing was suspicious.
Renyu looked away. "I was only thinking that it's... stranger than I expected."
Qian Renxue considered him for a beat. Then her fingers slid once through his hair, slow and absent-minded.
"Very well," she said. "You can keep your embarrassing thought for now."
Renyu did not relax at all.
She stepped back and the last trace of warmth vanished from her expression, replaced with cool attention. "Summon it again."
He obeyed immediately.
Soul power moved at the call almost faster than thought. Crimson light gathered in his palm, condensed, and the red crystal appeared once more—small, sharp, and unnaturally perfect. It floated above his hand like a piece of cut blood.
Qian Renxue circled him once.
"Any discomfort?"
"No."
"Loss of control?"
"No."
"Drain?"
He paused, feeling carefully. "Very little."
That answer seemed to please her. She stopped in front of him and looked directly at the crystal. Its light reflected faintly in Xue Qinghe eyes, turning them colder.
"It's stable," she said.
Renyu nodded.
More than stable.
The second summoning felt easier than the first. The panic and shock from awakening were gone now, leaving only a strange sense of familiarity. Like touching a tool that had always belonged in his hand even if he had only just found it.
He focused inward.
The crystal responded.
Or perhaps "opened" was a better word. Not fully—nothing like that. But now that he was actively looking, he could feel structure inside it. Layers. Compartments. Sealed spaces nested within the martial spirit like locked chambers behind locked chambers.
No usable skill surfaced.
No transformation came.
Yet the sense was unmistakable.
It was incomplete.
Not damaged. Not dormant in the ordinary sense. More like a mechanism waiting for the missing keys to be inserted one by one.
'Spirit rings.'
The thought made his pulse quicken.
Qian Renxue saw the change at once. "What did you feel?"
Renyu hesitated only because he was arranging to word it properly.
"It's empty," he said.
Her eyes narrowed.
He corrected himself. "No. That's not right. It feels... unfinished. Like something with places meant to be filled. The crystal itself is there, but what's inside it is still sealed."
Qian Renxue gaze dropped briefly to his right hand. "Fixed skill paths."
"Yes."
"And you can sense them already?"
"Not what kind of skills themselves." He frowned, chasing the sensation. "Only the fact that they exist."
She nodded once. "Good. That means the information wasn't merely instinctive nonsense. Try moving soul power through it."
Renyu did.
The red crystal brightened. Not dramatically, but enough that the edges grew sharper in the dim chamber. A faint resonance hummed through his arm, climbing from wrist to shoulder. There was no pain in it. Only pressure, precise and compact, as if the crystal were a lens compressing his soul power into something denser before letting it circulate back.
He took an involuntary breath.
Qian Renxue noticed. "Describe it."
"It feels concentrated."
"That is not useful."
He glanced up. "It feels like my soul power is being put through a narrower channel and returned cleaner."
That made her pause.
"Cleaner?"
"I think so."
She stepped closer. "Again."
Renyu obeyed, slower this time, tracing the path with care. Soul power moved from his core to his arm, into the crystal, then back. The return flow was not greater in quantity, but it felt tidier somehow. More obedient. Less diffuse.
When he opened his eyes, Qian Renxue was close enough that he could smell the faint incense on her robes.
"Well?"
He considered the sensation one more time. "It doesn't increase my soul power. But it makes it easier to control when passing through the crystal."
"A refining effect," she murmured.
"Maybe."
"That alone would already make it valuable."
Renyu looked down at the red crystal again.
Valuable was an understatement. A martial spirit that ignored ring-type compatibility and only cared about age and endurance was already absurd. If it also improved control from the beginning, then its future might be even worse than he had first thought.
Or better.
Depending on who was looking.
Qian Renxue reached out then, not touching the crystal itself but hovering her fingers a hair breadth from it. Her expression did not change, yet Renyu could feel how alert she had become.
"It reacts to my proximity," she said quietly.
He blinked. "What?"
"Summon it slightly higher."
He did.
The crystal rose to chest level between them. For one brief instant, the red light inside it flickered—no more than a pulse, but different from before. Warmer. Sharper. As if responding to something in her.
Qian Renxue eyes narrowed.
"Interesting."
Renyu stared at the crystal. "It didn't do that with me."
"No." She drew her hand back. "But it reacted to my soul power."
Or perhaps, he thought uneasily, to something even more specific than that.
Angel.
Sacred.
Light.
He did not say it aloud.
Neither did she.
The silence stretched just long enough to make the possibility uncomfortable.
Then Qian Renxue turned away first. "We'll leave that for later. You can dismissed it."
Renyu dismissed the crystal. Crimson motes scattered and vanished against his skin.
For the next hour, Qian Renxue tested him like a physician, a teacher, and a strategist all at once.
She had him summon and dismiss the crystal repeatedly until they were certain it caused no hidden backlash. She made him circulate soul power while standing still, walking, then moving through basic hand forms. She had him repeat the breathing routines she had drilled into him over the last two years and noted how much more stable his balance remained with the crystal active.
Then came the physical testing.
That part felt less like discovering a martial spirit and more like being reminded who Qian Renxue truly was.
She took him to an inner training room connected to the chamber by a narrow corridor. The room was bare stone, smooth floor, weapon racks along one wall, practice weights stacked in the corner, and not a single decorative object anywhere. Efficient and hidden.
Qian Renxue untied her outer robe and handed it to a waiting attendant outside the threshold without ever breaking stride.
"Again," she said.
Renyu summoned the crystal.
"Hold your stance."
He lowered into the horse stance she had forced him to learn long before his legs were truly ready for it. The red crystal floated above his palm.
"Lower."
He lowered.
"Back straight."
He corrected it.
"Circulate soul power."
Renyu obeyed.
At first it was manageable. Then minutes passed. Sweat began gathering behind his neck. The muscles in his thighs tightened. He kept the crystal active and the soul power flowing as evenly as he could.
Qian Renxue watched without sympathy.
Or rather, with her version of sympathy.
Which meant she did not lessen the standard just because he was young.
When his breathing changed, she noticed immediately.
"When the crystal is active, where does the strain build first?"
"Legs first," he said through his teeth. "Then shoulder."
"Not the meridians?"
"No."
"Good. Hold."
He held.
By the time she finally allowed him to straighten, his legs trembled slightly. She gave him exactly enough time to recover before moving to the next test.
Reaction speed.
Balance under sudden shifts.
Short bursts of movement while maintaining crystal activation.
Stopping and restarting soul power circulation without losing control.
By the end, Renyu was breathing hard enough that even speaking felt irritating.
Qian Renxue handed him water.
He took it and drank greedily.
"Well?" he asked at last.
She leaned one shoulder against the wall, arms folded, Xue Qinghe face calm as ever.
"Well," she said, "your body endured better than a normal child would. Seem like all that training has bear fruit."
Renyu gave her a flat look over the cup. "That sounds less impressive when you say it like that."
Her mouth curved faintly. "Would you prefer flattery?"
"No."
"Then don't ask foolish questions."
He looked away and drank the rest.
Qian Renxue tone shifted into more precise. "The whale glue worked. The training worked. More importantly, your crystal does not seem interested in delicate compatibility at all. It wants capacity."
Renyu lowered the cup.
He had reached the same conclusion.
His martial spirit was not asking, 'What kind of beast suits me?'
It was asking, 'How much can you bear?'
A very different question.
Qian Renxue stepped closer and placed two fingers lightly against his wrist, feeling the pulse there. After a moment she let go.
"You can handle more than the standard first-ring age," she said.
Renyu heart kicked once.
"How much more?"
"I don't know yet. Maybe a thousand years."
That was honest, which made it more serious.
She turned and walked toward the weapon rack, gaze distant in thought. "Ordinarily, the first ring is chosen conservatively because the ring must suit the martial spirit and not overwhelm the body. You've removed the first concern almost entirely."
"And the second?"
Her eyes came back to him.
"The second is still the difference between success and death."
The training room went quiet.
Renyu set down the cup carefully.
This was the real edge of it. Not talent. Not theory. Not the thrill of awakening something absurd and powerful.
Risk.
The same risk he had been preparing for since he first realized this world rewarded strength and kill the weaker.
Qian Renxue studied him for a long breath, perhaps expecting hesitation.
He had none.
Not because he was fearless.
Because he understood too well what settling for "safe" could cost later.
She saw the answer on his face and gave a very small nod.
"Good," she said.
Then she picked up a wooden practice blade from the rack, weighed it once in her hand, and added in the same calm tone she might have used to discuss weather or court schedules:
"Since any ring will do, then we will not choose safely."
Renyu breath slowed.
The red crystal phantom weight still seemed to linger in his palm.
Qian Renxue looked at him—at the child she had raised, tested, protected, and sharpened—and finished.
"We will choose the best your body can survive."
