Falling Off a Cliff While Collecting Medicine, Attaining the Tao and Cultivating Immortality

"Five Years of Cultivating Immortality in the Cave, and Now I Am Invincible When I Come Down from the Mountain"

I want to read a book like "I practiced immortality in a cave for five years and became invincible when I came down the mountain". An excellent novel among urban cultivation novels, a cultivation novel that I still want to read after reading it!
