The training grounds of the Grand Elder existed outside normal space.
Lin Xueyi stepped through the transmission array and felt the world shift. The Lin family compound—noisy, crowded, layered with political poison—faded into silence. She stood in a valley of grey stone and black water, where spiritual energy flowed in visible currents like mist through ancient mountains.
"This is Hollow Valley," the Grand Elder said. "My private domain. What you learn here, no one observes. What you reveal here, no one discovers."
She knelt on stone that was not stone—compressed spiritual matter, ancient and patient. "What do you teach first, Elder?"
"Measurement." He struck without warning.
A palm to her chest, Foundation Establishment power restrained to a whisper, yet enough to shatter a normal third-grade cultivator. Xueyi did not dodge. She compressed, folding her void-space around the impact point, dispersing force into the emptiness where her true cultivation resided.
The Grand Elder's eyes gleamed. "Again."
He struck ten times. She compressed ten times. Each impact taught her the limits of her technique—the microsecond delays, the energy costs, the precise threshold where concealment became exhaustion.
"Your mother could disperse strikes of Core Formation level," he said. "She died with that secret, killed by those who feared what she might become. You will exceed her."
They trained until her body failed. Then he taught her to restore—void-enhanced herbs from her space, compressed to medicinal density no alchemist could match, healing her in minutes what should take days.
"Second lesson: The Void Step in combat."
Not the partial technique she had used against Lin Zhan. The true movement—compressing space beneath her feet, appearing where she was not, striking from angles that violated geometry.
She failed a hundred times. Succeeded once. Failed again.
"Combat is not your strength," the Grand Elder observed. "Your strength is absence. The enemy who cannot find you. The strike that comes from nowhere. The cultivation that measures wrong."
He was right. She was not a warrior. She was an assassin who had not yet accepted her nature.
They trained for three days in Hollow Valley—nine days in the space's time. When she emerged, the compound had barely noticed her absence. The Grand Elder's disciple was seen as ceremonial, honorary, not transformative.
Let them believe.
The first test came from Ouyang Fang.
Not direct attack—Grand Elder protection made that suicidal. Instead: public challenge.
A clan gathering. Junior disciples required to demonstrate progress. Meiyu would perform—fourth-grade sword forms, elegant and deadly. And Xueyi, as the Grand Elder's disciple, would be expected to demonstrate something.
Failure would humiliate the Elder. Success would expose her depth.
Ouyang Fang smiled from her seat of honor, the trap perfectly set.
Xueyi stepped to the center of the training yard. The crowd was larger than expected—drawn by rumor, by the mystery of trash-become-disciple, by the hope of spectacle. She saw Yue in the back, pale and watching. Saw Han Chen absent, as always. Saw Chen Yu's servant observing from a distant roof.
"Demonstrate," the clan instructor commanded.
She chose qi manifestation. The simplest test, the most revealing. Cultivators projected their spiritual energy outward, formed shapes, demonstrated control. First-grade produced mist. Second-grade formed vague shapes. Third-grade achieved definition.
Xueyi projected nothing.
The crowd murmured. Failure? Trick? The Grand Elder misjudged?
She held the nothing for three breaths. Then, with precision calculated to appear as desperate effort, she produced a single thread of grey mist. First-grade. Barely. Unstable.
Laughter rippled. Pity. Dismissal.
But the Grand Elder, watching from his platform, nodded once. She had shown exactly what was needed: enough to satisfy obligation, not enough to threaten. The void's concealment held. The mystery remained.
Ouyang Fang's smile faltered. Meiyu's sword demonstration, flawless and fierce, suddenly seemed excessive. The girl who had defeated Lin Zhan, who had become the Elder's disciple, who had survived assassination attempts—she produced mist and was satisfied?
The trap had closed on emptiness.
That evening, Yue came again.
Not to the new quarters—Xueyi had not invited her. To the dilapidated courtyard, their shared childhood prison, where Yue still lived despite Xueyi's elevation. The same thin walls. The same rough doorframes. The same distance between sisters who had once huddled for warmth.
"You hid something today." Yue's voice was soft, uncertain, carrying the last echoes of the girl who had once trusted completely. "The mist was... wrong. Too controlled. Too satisfied."
Xueyi sat on her narrow bed, Hui hidden in the space, listening. "I am what I have always been, Yue. Trash that survives."
"Survival is not enough anymore." Yue's hand found hers, fingers cold with ambition she did not yet acknowledge. "The Crown Prince writes to me. He asks about you. He asks about... everything." Her eyes, beautiful and calculating, met Xueyi's. "I could help you, sister. If you trusted me. If you told me what you truly are."
The offer was genuine, Xueyi realized. The old Yue, the one raised by their mother's love, still lived in this moment. Still wanted to stand with her sister against the world.
But the new Yue, the one growing in Han Chen's shadow, wanted to use that knowledge. To trade it for status. To prove herself more valuable than the sister who had always protected her.
"I am nothing, Yue." She squeezed the cold fingers gently, releasing them. "Less than you. Less than Meiyu. Believe what you see, not what you imagine."
Yue left, unsatisfied, the door closing on an opportunity that would not return. The correspondence with Chen Yu would continue. The resentment would root deeper. The betrayal would grow toward its inevitable harvest.
But not tonight. Tonight, Xueyi entered her space and cultivated beside her garden, pushing toward seventh grade, preparing for the face-slapping.
The trash had survived.
The genius would rise.
