A soul that was about to be destroyed was saved by a woman and transformed into "persistence".
Although he also had the ability to go to heaven and earth, he also found that his memories of his life were sealed, not to mention why he died in the first place. But every time he wanted to let go of the past and start a new life, there seemed to be a voice calling him from the deepest part of his heart. He scratched his liver and lungs, but he couldn't resist his curiosity, so he asked the woman what kind of person she was and why she died?
But at first, the woman did not intend to tell him the truth. Until one day, the woman was suddenly hit hard. In desperation, she revealed part of the secret. It turned out that Zhi was a miserable existence. They could only survive by helping humans solve their troubles. Otherwise, they would be punished by God. Unless they could get confirmation from humans and collect nine memory fragments, they could open the dusty memories and solve all the mysteries. Lu was confused for a while, and finally chose to embark on an unknown journey...
If life is the most precious thing for human beings, then memory is as important as life to Zhi.
If one day, the attachment stops at a certain place and no longer travels, or if all memories of life are lost, it will become an unconscious soul, drifting in the wind. You may be swallowed up by evil creatures one day, or you may be driven by the wind forever, and you may never be able to stand still...
