Moonlight seeped through the skylight.
Ever since the night that question was left behind — the night "Why" fell into everyone's empty space — the fourth position — the empty space left for what had not yet appeared — had been breathing.
It was not one of choice, error, freedom.
It was something that had not yet grown.
That arc was still on the stone wall.
Ever since the night his left arm disappeared — the night the crack before the door first breathed on its own — it had been there.
But tonight was different.
Shen Yuzhu closed his eyes.
His left arm was no longer visible. Not transparent. Transparent means you know it is there, but light passes through. Not now. Now — at that position, there was no longer a thing called "arm."
When moonlight passed through there, it no longer bent.
Because bending itself no longer needed light to prove it.
That arc was still there. But its light source was no longer the moon.
It was glowing on its own.
Extremely faint.
Not blue, not white. The kind of light you see behind your eyelids after you close them. Not seen. Felt.
The mirror‑keeper stepped out of the shadows.
His shadow did not follow. The shadow stayed where it was, as if waiting for something.
Dust no longer fell, no longer drifted. Each grain of dust rotated at an extremely slow speed, as if remembering its own position.
He looked at the arc on the stone wall.
That arc was already more like moonlight than the moonlight itself.
He was silent for a long time.
Then he asked a question — not "how much longer can you hold on," because that was not a matter of the body.
"What if the door keeps needing you?"
Shen Yuzhu did not open his eyes.
Did not answer "then I will hold on."
Did not answer "then there is nothing I can do."
Did not answer any sentence about "I."
He only said one sentence.
His voice was very light, like snow falling on snow.
"Then let it keep passing through."
The mirror‑keeper listened to that sentence.
For a long time, he did not speak.
The arc on the stone wall, in that moment, brightened a thread. Not becoming brighter. Being needed for a moment.
The mirror‑keeper's shadow stood up from where it was, walked over, and crouched beside Shen Yuzhu.
Not following, not side by side.
It said nothing.
It was only:
"I am here."
At the bottom of Shen Yuzhu's empty space, the three word‑roots — choice, error, freedom — had stopped moving.
Not still.
They had finally stopped needing to "point."
Because the fourth position was growing.
That position "reserved for what had not yet appeared" — which had been breathing ever since the night that question was left behind — tonight, it was no longer just an empty space.
It began to have a contour.
Extremely faint. Too faint for the naked eye to see.
But the mirror‑keeper saw it.
Not a shape. "Becoming shaped."
"What is it?" he asked.
Shen Yuzhu was silent for a breath.
"I don't know. But it does not need me to name it. It only needs — me to still be here."
The outline of his left shoulder, in that moment, faded a thread.
Not disappearing.
The fading was no longer happening to him.
Something in him had begun to step aside.
The mirror‑keeper did not ask again.
He crouched there. His shadow curled at his feet, quiet.
Everything in the underground Astrology Tower, in that moment, stopped for an extremely short beat.
Not time standing still.
The world was remembering that shape.
Capital. An office. The same night.
A middle‑aged clerk sat at his desk.
His breathing was neat as a ruler, not a single empty space.
But his left hand — the hand holding the brush — was trembling.
Not cold, not illness.
His body remembered: a few days ago, he had passed the stairwell of the Astrology Tower and looked inside. He had seen that arc. He did not know what it was, but his empty space knew.
That night, an extremely short pause had appeared in his breath — so short he could pretend it had not happened.
But he could not sleep.
Not because of insomnia.
Because his body did not want to lie down — when he lay down, that pause would lengthen a thread.
He told no one.
He did not even tell himself.
He only continued going to work every day, continuing to breathe, continuing to press.
But his left hand remembered.
Tonight, as he wrote, the tip of his brush stopped.
Not his decision. His hand stopped on its own.
He looked at the unfinished character beneath the brush tip.
Not "Qi," not any character with meaning.
Only a stroke written halfway.
He did not continue writing.
Nor did he cross it out.
He only let it stop there.
In his breath, that extremely short pause — for the first time, breathed once on its own.
Not deeper, not shallower.
Acknowledged for a moment.
Then he pressed it back.
He did not know.
But his left hand remembered that half‑breath.
The direction of that half‑breath was exactly the same as the arc on the stone wall of the Astrology Tower.
Not a copy.
Touched by the same shape.
Underground, Astrology Tower.
The arc on the stone wall — which had never left since the night Shen Yuzhu's left arm disappeared — in that moment, was no longer just breathing.
It emitted an extremely faint light.
Not illuminated by the moon.
Glowing on its own.
That light fell on the mirror‑keeper's face.
His shadow did not tremble.
Dust did not fall.
Shen Yuzhu did not open his eyes.
But the corner of his mouth moved.
Not a smile.
"Still here."
The mirror‑keeper said quietly, "You are becoming — something that can exist without a body."
Shen Yuzhu did not answer.
The arc on the stone wall, in that moment, brightened for an instant.
Not a response.
Acknowledged.
The contour of the fourth position deepened another thread.
Not becoming deeper.
Being needed for a moment.
His left shoulder, in that moment, did not continue fading.
Not because it had stabilized.
Fading no longer seemed to belong to him.
The mirror‑keeper did not speak again.
Moonlight fell from the skylight.
Fell on the stone wall.
Fell on that arc.
Fell on the place where Shen Yuzhu's left arm should have been.
There was nothing there.
But when moonlight passed through that place.
It lingered a moment longer than elsewhere.
As if passing through a door.
He was not a sacrifice.
He had only become — a place the door could pass through.
And that arc —
for the first time,
was not seen,
but glowed on its own.
Breathing continued.
