Weird Cultivation of Immortality, I Use My Demonic Heart to Prove the Great Path

Others rely on talent to cultivate immortality, while Ling Xiao relies on longevity to cultivate immortality. The soul travels through the strange world of immortality, and his only ability is [immortality]. Is the technique difficult to practice? I've been practicing for a hundred years! Is it difficult to kill a strong enemy? I'm waiting for him to die of old age! God's plan? I will accompany you to the end of the universe! This is the ultimate "gou" way of a paranoid patient, who spends time sharpening his demonic mind and uses mortal wisdom to do things that defy nature.
