Immortality

Looking for a Great Novel About Long Life or Immortality

Looking for books like The System Grants Me Immortality, and I'll Eventually Become Invincible (The Ashes of Immortality). For example, Chen Xun, the Dao Ancestor, from The System Grants Me Immortality, and I'll Eventually Become Invincible. Oh, right, I forgot the title has been changed to The Ashes of Immortality.
