Aura is the "one" that evolves all things, and the reduction of aura is an irreversible process. Immortals are aura creatures, and they need to change and innovate in order to survive.
After the fusion of ideas again and again, these major schools and their main lines emerged:
Since you can't change, you just have to adapt. ——Martial arts
Study the specifications of heaven and earth, abandon this remnant body and use your body to conform to the Tao. ——Only the Way of Heaven
Study the principles of heaven and earth and find a place of transcendence. ——Ascension Alliance
The loss of aura is unavoidable, but we can create aura. ——Incense Shinto
The story of the novel starts from the martial arts side.
