In the clockwork universe where the planet relies on huge gears, the sky suddenly turns a strange moss green, but only the exiled cloud shepherd Yun Ji remembers its original color. The luck value above his head was permanently locked at -99, and he was accompanied by the counter-rotating cloud beast all day long, until he discovered that gravity began to reverse randomly, and the entire gear civilization was on the verge of collapse. The ruling House of Prophets blamed "unlucky people" like him for the disaster and launched a purge.
