There are gods three feet above your head, and a good-fortune ruler three inches above your right shoulder. Don't touch my right shoulder, or you'll rub off my good fortune. The ruler reveals your luck in full: when you're lucky, even your attempts to block it won't work; when you're unlucky, even plain water will get stuck in your teeth. The protagonist uses the ruler to write his own life story, with wealth and beautiful women pouring in. Whoever sees the ruler will be blessed.
