After recalling memories of my past life, I spent ten years— Ten years taking care of a senile old man who called himself the Sword Saint. Ten years like that. Finally, I was about to receive my reward. "Arthus, go and get engaged to my granddaughter." The old man's name was Hans Messiah. The old man truly was the Sword Saint, a living legend of the Messiah Sword Saint family, and I became engaged to the Sword Saint's granddaughter. *This cover was created with AI.
