Shen Mo's life is composed of silk thread, ancient silk and silence. In a deep corner of the city museum, he was restoring embroidery paintings that had been worn away by time. Until one rainy afternoon, he took over a fragment of an ink embroidery scroll from the late Qing Dynasty that had no signature and only half of it. The embroidery was a black butterfly flying against the wind. When the tip of his needle guided the first strand of black silk thread through the warp and weft of the ancient silk, the birthmark on his left wrist suddenly became hot. The silk thread on the embroidery stretched without wind, and the space in front of me swayed like water ripples. He saw another version of himself, sitting in a studio with a similar layout but full of weirdness, placing the last stitch on the same embroidery. Two time and space are subtly overlapping at this moment because of an embroidery. Shen Mo gradually discovered that the fragment was not an ordinary embroidery, but an "anchor" connecting parallel time and space. Every time he drops the needle, he is silently moving the warp and weft of the two worlds. In another time and space, intangible cultural heritage skills have not declined, but have given rise to unimaginable power and disputes. Before the restoration is completed, he must find the rules of travel, deal with prying eyes from the other world and his own confusion, and also unlock the real secret of the "Time and Space Embroiderer" guarded by the Shen family for generations.
