In the Dream, the Flowers Fall Most Sadly

Yao Yao Galaxy, a song of farewell, how much do you know about the worldly affairs of the world? There is such a young man who, with a sword in his hand, kills evil spirits and performs chivalry, comes from the world of mortals and goes to the world of mortals. But the world of mortals is like a dream. Can the chaos of the world of mortals be eradicated? As the saying goes, a dream comes to life and the world of mortals passes. How? But I don't know what the world of mortals is, except that you and I are all guests in the world of mortals. Why not come together to dream and look at the flowers in this dream. Perhaps, through this young man's journey in the world of mortals, we will also get the answer in our own world of mortals.
