Mingyi is a concept in the Book of Changes, which means darkness descends and the world falls into chaos. In a world close to the time of Chinese legend, there are two gods representing Yin and Yang (light and darkness), the King of Wood and the King of Gold. After ten ancient suns perished, the gods disappeared from the earth, until a thousand years later, the witch destroyed the sun and tried to resurrect the golden king of the undead goddess. This is a story about the adventures of a group of teenagers with different personalities.
