Global: The Healer Was Supposed to Be a Support, So Why Can They Kill Instantly?

Games have invaded reality, and the world's rules have been rewritten. Monsters run rampant! Humanity has entered an era where everyone changes class! Only those with powerful classes can rise above the rest and take control of their own destinies. But on the day he changes class, Chu Yun gets stuck with the most useless support class, [Doctor], and his bubble-tea-loving girlfriend dumps him on the spot! Faced with mockery and humiliation, Chu Yun snaps! The Infinite Rule-Reversal System activates! [Shield of Protection] is super-reversed: reflects 1,000% damage, killing anyone who attacks on the spot! [Battle Fervor] is super-reversed: his opponent, caught up in a surge of fighting spirit, suddenly loses focus and charges toward the fat pig between his teammate's legs! [Holy Light Healing] is super-reversed: sacred light descends, and all enemies lose health! The enemies cry, “What is going on? Isn't holy light supposed to heal?” Who says doctors are useless? Doctors are rising today!
