In Shanghai in 1937, famous opera singer Cheng Yuetang's sleeves contained a quantum code that could detonate a Japanese military laboratory. When the emerald radiation dyes the score of "The Peony Pavilion" red, her encounter with the upstart business world Lu Yanzhi reveals the century-old plan of the Cheng School Theater Troupe: to forge Chinese blood into sonic weapons and rewrite the genes of civilization at the singularity of the Yangtze River's reverse flow. From the spy scene in the concession to the interstellar reverberation, half of the blood-stained sleeve runs through four levels of time and space, singing a swan song of "love" composed of radiant flesh and blood between the Fukushima nuclear cloud and the bronze of Sanxingdui.
