Immortal Sword of Butianque

The sky and the earth are dark and yellow, and the universe is primitive. The world and time are like a mirror, interpreting different stories at different latitudes. Ancient myths have projections in various worlds, and the innate gods and demons in the myths begin to interpret their own legends based on their own projections. In one of the worlds, the legend of mending the sky and a true spirit left behind after mending the sky extended to trigger a more magnificent story in the future.
