One Piece: You Can Become Stronger by Sleeping

Travel through the world of pirates and awaken the deep dream system! As long as you sleep, your body's strength can be increased infinitely at a rate dozens of times more efficient than the most strenuous training! You can also gain enlightenment and jump thousands of miles no matter what skill you have! You can understand the artistic conception even by looking at the leaves! "Why? Why have I worked so hard, so hard, so hard! Why is the gap between me and you still getting bigger and bigger? You're obviously just sleeping all day long!" "If you are too talented and guilty, then even if you die a hundred times, it won't be enough." No one can understand the pain that cannot be understood and cannot be expressed in words.
