This question was related to a well-known novel called " Battle Through the Heavens." This was a fantasy novel with cultivation as its theme, which told the story of a young man's growth. In the novel, people with low spiritual roots had shorter lifespans while those with high spiritual roots had longer lifespans. This was because the awakening of one's spiritual roots determined one's lifespan. In the novel, the main character Xiao Yan awakened his spiritual root at the age of seven, which determined his lifespan. Through Xiao Yan's growth, the novel showed the charm and power of training, and at the same time, the complexity of human nature.
