This is a world where "cultivating immortals is actually changing one's destiny against nature."
Everyone has a "natal hexagram" when they are born. Good or bad luck, life span, fate, disasters, etc. Are all written on the birth chart. The essence of cultivating a monk is not to simply absorb spiritual energy, but to use one's own cultivation to leverage destiny, change evil into good fortune, and turn death into life.
But changing your life comes at a cost.
Every time a monk breaks through a great realm, he must sacrifice a piece of his own true memory.
The higher the realm, the more precious the memory of sacrifice. In the end, people will become stronger and become gods, but they may forget why they set out and the person they once wanted to protect the most.
The heroine Ci Luo was born in Yunshuo City in the Mortal East Region. She was an orphan and relied on the ancestral compass of destiny to practice. She can see fragments of the future, but she can't really change all endings. Along the way, she changed her destiny against the will of heaven, lost her memory along the way, and watched the people around her separated, sacrificed, and perished.
Finally, she climbed onto the Conferred God Platform, only to find that she had forgotten what she wanted to go to in the first place.
