Immortal Cultivation World: My Dissatisfied Father

[Plain + Immortality + Farming] [Cultivation to Immortality + Becoming a Saint] My father has been alive for who knows how many years. He has never fought or robbed anything. He keeps to himself and is a bit unfulfilled. First life "It doesn't matter, he is my father." Second life "It doesn't matter, he is my father." Third life "It doesn't matter, huh? Why is he still my dad?"
