In the silkpunk world that relies on bamboo and wood machinery and giant kites suspended in the sea of clouds, sleep is a fatal curse. Cloud Shepherd Lin Feng, a lonely man who firmly believes in the laws of nature, has devoted his life to using science to debunk the superstition of "sleep death". When he witnessed the sky turn into an eerie green under the influence of hurricane "Long Song", and no one in the world noticed the abnormality, he realized that he had broken into the biggest secret of this exquisite world. In order to pursue the truth, he must drive a kite boat deep into the eye of the eternal storm that has consciousness and sings elegy, and face the discovery that may subvert the foundation of civilization: perhaps the "magic" they fear is protecting them from some more terrifying and real, cold and great science.
