Mo Bing is a divine bird that feeds on negative energy, a savior bird born at the dawn of a world's destruction.
But once the world was saved, the end-times bird had nothing left to eat.
For the sake of a meal, Mo Bing could only travel between different worlds.
First world: The miserable wife tricked into marriage by a eunuch chief minister (The divine bird trains her husband on the spot!) She spent half her life working hard and the other half suffering, only to discover in the end that she was nothing but a prop.
Second world: The original wife betrayed by the founding emperor (The divine bird takes control of the army and keeps him up at night!) When you have a beloved wife and concubines in your arms and power in your hands, do you ever think of your first wife, still toiling away?
