Stop Grinding, Our Sect Is the Lying-Flat Type

Li Xianyu transmigrates into the cultivation world and binds a "Lie Flat and Get Stronger" system—the more he slacks off, the faster his cultivation grows. But fate simply won't let him lie flat. The elders force him to revive the sect, the disciples urge him to lead everyone in grinding together, the neighboring Sword Sect comes knocking for a challenge every day, and even the Heavenly Dao sends him tribulation lightning every few days to hurry him along. Li Xianyu howls at the sky: "I just want to quietly be a salted fish, why do you all insist on forcing me to become a saint?!" This is a hilarious story where others cultivate through hard work, while he cultivates through slacking off. — Description from novelcodex.org
