It's Totally Reasonable for a Healer to Abuse Bugs and Deal 999 Damage per Hit!

A global online game, Godhunt Realm, invades reality. Everything is digitized, and in-game death means permanent demise. In his past life, Lin Chen was brutally betrayed by his lover and a vengeful rival. As a dedicated Healer, he was stripped of all support mid-dungeon, ambushed and killed. His rare gear was looted, leaving him to perish in bitter regret. Reborn three hours before the game’s global descent, he returns to the eve of catastrophe. As the game’s exclusive bug fix developer, he knows every hidden, unresolved glitch in the system. In his previous life, he had diligently fixed every bug, only to meet a tragic end. This time, he defies fate. He abandons bug repairs, tampering with the core code to monopolize all game-breaking glitches for himself. He modifies the Rusty Iron Sword to unlock a hidden 50% critical strike chance. Paired with the loophole of the Lucky Ring, every critical kill permanently boosts his attack power without fail. The Pocket Potion Can grants infinite gold coins, and the first-death achievement rewards a universal max-tier skill book. Three supreme bugs become his exclusive cheats. While all other Healers solely focus on buffing and healing, grinding levels and clearing dungeons painstakingly, Lin Chen stacks infinite attack power with his humble rusty sword, soaring to unimaginable combat strength. When he finally reveals his true power, his devastating 9999 damage crits shock the entire player base! "Insane! This Healer isn’t healing—he’s one-shotting bosses!" "Run! Never mess with this bug-abusing battle Healer!" Given a second chance at life, he will settle every betrayal, scheme, and debt. He will reclaim everything he lost and climb to the supreme peak of Godhunt Realm!
