Ling Fan transmigrates and gets bound to a Slacker System. Other Systems teach their Hosts to dominate the martial world, amass wealth beyond measure, and marry a fairy to reach the pinnacle of life. His System teaches him just one thing: lie flat. Don't lie flat and you die; lie flat and you get paid. Sunbathing can even keep you alive longer. Ling Fan says, "Now this is a job I know how to do." So every day, he sleeps until late morning, squats by a wall, and happily photosynthesizes in the sun. He scrapes by on sunshine, his Slacker Points steadily rising. Life is poor, but comfortable enough. Then one evening, the leader of the Martial Alliance kicks down the gate at the entrance to his village, points at him, and roars, "You! You're the one who drained the spiritual energy from a hundred-mile radius! You even drained the trees!" The meat bun in Ling Fan's mouth nearly chokes him to death. "It wasn't me! I didn't do it! I was just sunbathing!" The System chimes and pops up: [Congratulations, Host, on achieving the 'Forced to Take the Blame' achievement. Reward: Lie-Flat Divine Art, First Layer. Please maintain your laid-back mindset and survive while being hunted.] Ling Fan looks at the martial experts converging from every direction, then at his meager spiritual power, which couldn't even crush an ant, and falls into deep thought. Does this System want me to win by doing nothing, or lie down for good?
--It is only later that Ling Fan learns the sun he has been basking in is the real Sun. The spiritual energy he has been absorbing really does come from a hundred-mile radius. The Lie-Flat Divine Art he practices is an ancient, long-lost Heaven-Swallowing Demon Art. And the entire martial world is already on its way to hunt him down.
