I Just Wanted to Lie Down, but the Goddess Asked Me to Save the World

The day the Salted Fish Knight was reviewed, the capital city exploded. I was forced to save a twelve-year-old princess, and my life began to take off. I sleep while others practice cultivation, and I break up fights with others. My dream is to eat and wait for death, but I always "accidentally" show off my skills at critical moments. Until I fell into the future for her and witnessed the end of the world. The girl I raised has become the last faith of the human race, the Radiant Valkyrie. She reached out to me in the midst of thousands of troops, her voice choked with sobs: "Have you rested enough? My salty fish knight. If you have rested enough, come back... And be my savior."
