Comprehensive Martial Arts: Taking the Cute Baby into the World

He was once a sword, an indestructible sword in the army that could split mountains and rocks. He was once a ghost, a bloodthirsty and murderous military ghost hiding in the shadows. Now that the military god has passed away and his wife has passed away, he no longer wants to be involved in this treacherous and chaotic world. He just wants to spend the rest of his life peacefully, watching the wind, rain, mountains, and flowing water with his daughter, watching his daughter grow up day by day, and sending her off to get married! But for his daughter, he had to come back to the world. What kind of story would such a person have in this world full of blood, morality, and betrayal?
