This is a dark age, a cruel world, a purgatory for all living things, and a nadir for the Han people. A modern office worker transmigrates a thousand years into the past into Yue Yun's body. The realm is plagued by the brutal Jurchen, a corrupt and incompetent court, treacherous ministers in power, and demons running rampant. The road ahead is a boundless purgatory of swords and fire; retreat means an age-old miscarriage of justice, sealed by twelve golden decrees. Will he merely seek to protect himself, or turn the world upside down and change the dynasty? See how Yue Qingyun mends the rift in the heavens and saves them from collapse.
