I Became the World BOSS by Acting Bad.

The modern earth suddenly regains its aura, and the world enters an era of job change for all people. Everyone at the age of 18 must participate in the profession transfer ceremony and awaken their professions: warrior, mage, assassin, priest, swordsman, druid... The whole world is going crazy: You have to practice in class, practice while eating, and practice while sleeping. The stronger your profession, the more you have to roll. If you don't roll, you will be beaten to death by monsters, surpassed by classmates, and eliminated by the sect. Only the protagonist, Su Liang, has awakened his only hidden profession: Master Liping. Others rely on hard work to become strong, but he relies on: Fishing, sleeping, being in a daze, messing around, fishing, being lazy, and paddling with pay to become stronger.
