79: Master Qing's Final Lesson
The fifth and final quarterly meal at the teahouse on the western edge of the royal city took place on the seventh day of the fifth month of the spring — exactly three months and seven days after the fourth.
Master Qing was already seated. The pot of *cloud-summit* tea was warm. The seventh substrate-anchor stone was on the writing table, beside its careful preceding small private companion case.
Su Yan inclined his head.
He sat.
Master Qing poured.
They drank, in the same beat, the first sip.
Master Qing set his cup down.
"Su Yan. The careful preceding small private final teaching."
"Master Qing."
"By my preceding read," Master Qing said, in his plain quiet voice, "you have — in the careful preceding small private hour of the past nine months of preceding small private quarterly meals — accumulated *six* of the seven substrate-anchor stones. The seventh is on the writing-table. With the seventh, your substrate-anchor pair is, by the careful preceding small private hour of the calibration's preceding small private requirements, *seventy-five percent complete*."
He paused.
"The remaining twenty-five percent," he said, "is — by the careful preceding small private hour of the calibration's preceding small private final requirement — *the substrate-trace of the careful preceding small private central facility itself*. You will, by my preceding teaching, *gather* it on arrival. The gathering will, by your preceding small private substrate-anchor stones' preceding small private final resonance pattern, *complete* the pair *during the extraction operation*. Once complete, the pair will *remain* paired until you, by your own preceding preference, dissolve it."
He paused.
"This is the careful preceding small private final teaching."
He drew, from the inner sleeve of his pale-grey scholar's robe, a small careful preceding small private folded sheet of plain rice paper.
He laid it on the writing-table.
Su Yan unfolded it.
It contained — in Master Qing's careful preceding small private flowing hand — *the precise mathematical formulation* of the substrate-anchor pair's preceding small private final calibration ritual. Eight equations. Three diagrams. A small careful preceding small private list of seven possible failure modes and their preceding small private corresponding remediation procedures.
It was — by Sebastian Yan's careful preceding small private read — *exactly* the preceding small private piece the seventh book of his mother's cellar set had been *missing*.
His mother had — by her own preceding small private preference at the careful preceding small private hour of writing the seven books — *not* included the final calibration ritual. She had, by Master Qing's preceding-time refusal at her preceding small private first meeting at his Royal Academy study fifty years ago, been required to leave the careful preceding small private hour of the final calibration *for someone else to teach her son*.
Master Qing had — by the careful preceding small private hour of one third small private letter ten years ago, by the careful preceding small private hour of fifty years of preceding-time waiting since his preceding refusal of her preceding small private first request — *now* taught it.
The careful preceding small private piece was complete.
Su Yan inclined his head, in the careful preceding small private upstairs back room, all the way to the writing-table.
He held the bow for a long count.
When he lifted his head, his face — by the small careful preceding small private discipline of seventeen months — *did not move*.
But the ember in his chest pulsed — slow, considered, *gentle*, *grave*, and *gentle* once more.
Master Qing inclined his head — small, formal.
"Su Yan."
"Master Qing."
"The careful preceding small private hour of the extraction will, by my preceding read of your preceding small private preparation, *succeed*. I am — by my own preceding preference — *not worried for you*. I am — by my own preceding preference — *waiting for the careful preceding small private hour your mother walks into my study at the Royal Academy with you at her preceding small private side*."
"Master Qing."
The two of them rose.
They inclined their heads — small, formal, by the careful preceding small private mutual courtesy of two scholars whose preceding small private fifth and final meal at this teahouse had, by the careful preceding small private hour of the final teaching, *closed*.
Master Qing departed first.
Su Yan departed second, by the unmarked carriage line.
By the careful preceding small private hour of the carriage's preceding small private return to the embassy, he carried — in the careful preceding small private inner pocket of his outer robe — *seven* substrate-anchor stones, *one folded sheet of mathematical formulation*, *one folded letter from Cang Xueyi*, *the cracked pendant in its cotton wrapping*, and the careful preceding small private private weight of one Heavenly Immortal's preceding small private fifty years of preceding waiting.
The careful preceding small private extraction — by the small careful preceding small private hour of one final teaching — was, by his preceding revised estimate, *exactly seven days* away.
He filed the calibration.
In his chest, the ember pulsed — slow, considered, *grave* — and the dry voice, very quietly, said: *Seven days. Use them.*
Su Yan inclined his head, in the rocking of the unmarked carriage on the careful preceding small private return through the royal city's spring streets, in the direction of the ember.
The careful preceding small private hour of the careful preceding small private extraction's preceding small private final preparation — *began*.
