Cultivation of Immortality in Old Age, Rejuvenation Through Rejuvenation

Qi Lu traveled to the world of immortality and became a casual cultivator. After seventy years of inaction, I thought my end was coming, but I didn't expect that I unexpectedly gained the ability to rejuvenate. As long as you continue to practice, you can reverse yourself, from old age to youth, from weak to strong. Many years later, Qi Lu suddenly discovered that he had transformed from a dying old man into a giant of immortality with endless longevity.
