The chamber did not return to its former stillness.
Though the writhing black mist had been sealed away, something unseen still lingered—like the faint echo of a storm that had not fully passed. The spirit lamps flickered softly, their glow steady yet dimmer than before, as if even light itself tread cautiously within this space.
Zheng stood motionless for a long moment, his gaze fixed on Old Master Chen.
Then, quietly, he spoke.
"We continue."
Mei Chen blinked. "Now?"
Zheng did not look at her. "The core has been removed, but its roots remain embedded within his meridians and spirit channels. If left unattended, they will regenerate… slowly, but inevitably."
Her expression tightened. "Then what do you need me to do?"
This time, Zheng glanced at her.
For a brief second, his eyes softened—just slightly.
"Stay calm," he said. "And watch carefully."
There was something different in his tone. Not cold instruction. Not detached command.
Guidance.
Mei Chen felt it.
And for reasons she could not explain, her heart steadied.
Zheng turned back to the jade platform and lifted both hands. This time, he did not reach for more needles immediately. Instead, he closed his eyes.
The air shifted.
A subtle pressure spread outward—not oppressive like before, but deep… vast… like the quiet weight of an ancient mountain.
Threads of spiritual energy began to gather around his body, faint at first, then growing clearer. Unlike the sharp, precise streams he had used earlier, this energy was gentle—flowing like water, circling him in slow, controlled currents.
Mei Chen watched, her breath unconsciously slowing to match the rhythm.
Zheng's voice came softly.
"The poison has taken root in three primary pathways—heart, lung, and spirit vein."
As he spoke, he raised one hand and extended two fingers.
A thin strand of light formed at his fingertips.
"This time… we don't force it out."
The light descended.
It touched Old Master Chen's chest.
Instead of piercing like a needle, it seeped inward—like a thread being drawn into fabric.
The old man's body trembled faintly, but not violently as before.
Zheng opened his eyes.
"Guide it," he said quietly.
Mei Chen startled slightly. "Guide… what?"
"The flow," Zheng replied. "His energy is too weak to respond on its own. I'll create the path—you stabilize it."
She hesitated.
"I've never—"
"You have," Zheng interrupted gently. "You just don't realize it."
Her brows furrowed.
Zheng met her gaze fully now.
"When you held his hand earlier," he said, "his breathing steadied."
Mei Chen froze.
"That wasn't coincidence."
Silence fell between them.
Something warm, fragile, and unfamiliar stirred in her chest.
Zheng turned back before she could respond.
"Place your hand here," he said, gesturing to Old Master Chen's wrist.
She stepped forward slowly, kneeling beside the platform. Her fingers trembled slightly as she reached out, then gently rested against her grandfather's pulse.
It was faint.
But steady.
"Close your eyes," Zheng said.
She obeyed.
"Don't think. Just feel."
Zheng moved again.
More threads of light emerged from his fingers—this time multiple, each one entering a different point along the old master's body. They moved like delicate streams, weaving through unseen pathways, reconnecting something that had been broken.
"Now," Zheng murmured, "follow it."
Mei Chen focused.
At first, there was nothing.
Then—
A faint sensation.
Warmth.
It was subtle, like the first touch of sunlight at dawn.
She inhaled sharply.
"I… feel something."
Zheng nodded slightly. "Good. Don't chase it. Let it come to you."
The warmth grew.
Slowly, gently, it spread from her fingertips into her arm, then deeper—until she could almost sense the fragile currents moving within her grandfather's body.
Weak.
Disordered.
But there.
Zheng's voice remained calm.
"Stabilize the flow around the heart channel. Don't let it scatter."
Mei Chen concentrated, her brows knitting together. The warmth wavered, almost slipping away—
Then steadied.
Zheng watched her from the corner of his eye.
A faint, approving glint passed through his gaze.
"Not bad," he said quietly.
Mei Chen didn't respond.
She couldn't.
All of her focus was consumed by the delicate balance she was trying to maintain.
Zheng continued his work.
The threads of light deepened in color, becoming more defined as they moved through the old master's body. Occasionally, faint traces of dark energy surfaced—thin, almost imperceptible remnants of the poison.
Each time they appeared, Zheng intercepted them immediately, dissolving them before they could spread.
Minutes passed.
Or perhaps longer.
Time seemed to lose meaning within the chamber.
Then—
Zheng's expression shifted slightly.
"There."
A faint ripple passed through Old Master Chen's body.
His breathing deepened.
Color returned more fully to his face, no longer just a fleeting improvement, but something more stable.
Mei Chen felt it too.
The warmth beneath her fingers became steady—stronger.
Alive.
Her eyes opened instinctively.
"His pulse… it's stronger!"
Zheng allowed himself a small exhale.
"The secondary pathways are cleared," he said. "For now."
He withdrew his hands slowly, the threads of light dissipating into the air like fading mist.
The chamber fell quiet again.
But this time—
It felt different.
Lighter.
Mei Chen remained where she was, her hand still resting against her grandfather's wrist.
She looked at Zheng.
Really looked at him.
His posture had relaxed slightly, but there was a faint weariness now—subtle, but undeniable. A thin sheen of sweat lined his brow, and his breathing, though controlled, was heavier than before.
"You're… exhausted," she said softly.
Zheng gave a faint, dismissive shrug. "It's nothing."
"It's not nothing," she insisted.
He glanced at her, slightly surprised by the firmness in her voice.
Mei Chen hesitated for a moment, then reached into her sleeve and withdrew a small silk cloth.
Before she could second-guess herself—
She stepped closer.
And gently pressed it against his forehead.
Zheng froze.
It was such a simple gesture.
Yet—
Unexpected.
For a brief moment, neither of them moved.
Mei Chen seemed to realize what she had done only after the fact. A faint flush rose to her cheeks, but she didn't pull away immediately.
"You should rest," she said quietly, her voice softer now. "Even if you won't admit it."
Zheng looked at her.
Not as a patient's granddaughter.
Not as an observer.
But as her.
Something in his gaze shifted—just slightly.
"…You handled the flow well," he said.
It wasn't a deflection.
It was genuine.
Mei Chen blinked, caught off guard.
"Is that… your way of thanking me?"
Zheng's lips curved faintly. "Something like that."
A small silence followed.
But it wasn't uncomfortable.
If anything—
It felt… warm.
Mei Chen lowered her hand slowly, clutching the cloth lightly as she stepped back.
Her heart was beating faster than it should.
And she didn't understand why.
Zheng turned away, resealing his satchel, his expression returning to its usual calm—but not entirely.
Because for the first time—
His movements were just slightly less precise.
"Prepare the materials I asked for," he said. "The next treatment will be more difficult."
Mei Chen nodded.
But as she turned toward the door, her steps slowed.
She glanced back at him.
Zheng stood beneath the soft glow of the spirit lamps, his figure calm, steady… yet carrying a quiet weight she hadn't noticed before.
Not just skill.
Not just mystery.
But something deeper.
Something… human.
Her fingers tightened slightly around the silk cloth.
And without realizing it—
A faint, almost imperceptible smile touched her lips.
Outside the chamber, the doors had yet to open.
And in the corridor beyond—
Lu Chen still waited.
Listening.
Watching.
Because whatever was happening inside—
Was no longer just treatment.
It was change.
And change…
Was dangerous.
