"The original is the end, so we know the theory of life and death." Xia Dong, who didn't know the past, didn't understand the present, and didn't want the future, started to search for his mother in a foreign country due to family changes. After going through many hardships, he found himself trapped in the "immortality puzzle", and he was actually the "introducer" of this puzzle!
The fantasy adventure allows him to set aside history, get a glimpse of human nature, and see the future. Should he choose to pursue his dream of immortality and break out of the cycle to realize "knowing his destiny but no results" and realize his ultimate long-cherished wish in life? Or should we insist on the theory of life and death to control the way of heaven and earth, abide by the "impermanence of cause and effect", and guard the four seasons of reincarnation of the years?
If you ask about your desires, you will find them endless; if you ask about your human heart, you will still know nothing!
