My System Only Wants Me to Kill

Tang En’s life was a bland, ordinary joke. Dumped for being 'plain,' he died a pathetic death by electrocution. Reborn in a harsh fantasy world, he quickly learned survival was no game – he couldn't even hunt a chicken. Then, a cold, elegant voice echoed: \"Welcome, new generation of System Killer.\" An 'Assassin System' forced itself upon him, complete with a snarky butler, promising power, stealth, and survival skills. Tang En, the former gaming casual, began to reluctantly level up, mastering skills he never knew he needed. But his first mandatory certification quest? To assassinate Father York, the beloved, kind priest who saved his life. Refuse, and the system would obliterate him. Comply, and betray the last shred of his humanity. What will a reluctant killer choose?
