In the silk punk world that relies on silk, wooden kites and sky sails to float in the clouds, Mu Yun Renlan's daily life is to herd the giant cloud whale and measure loneliness in the silent sky. He longed to leave traces of his existence among the vast machinery and ancient clan traditions. Until one day, he witnessed the sky being dyed with a strange green color that only he could see, and discovered that the sky was peeling off like glass and falling to the earth. Holding a fragment with an unknown "true name" in his hand, Lan is forced to embark on a path of exploration. He will reveal the horrifying truth that "Sky Vault" is actually a testing ground for imprisoned civilization, and that "True Name" is the underlying control code, and face the ultimate choice: whether to call on the true name of the General Controller to repair the false but stable cage, or to use himself as the fire to ignite the dawn of freedom that is destined to be destroyed but may be the only real one.
