I'm a Deliveryman, and It's Perfectly Reasonable for Me to Take Out Impostors One by One

The monster opens its gaping maw, its barbed tongue coiling tightly around Wen Che’s neck. “Human, can you feel the fear?” Wen Che glances at the countdown on his phone, his eyes bloodshot. “Fear your grandpa! This delivery is three minutes from being late. Are you paying me the 50-yuan bonus?!” With a quick counter, he combines [Instant Teleportation, No Windup] with [Untargetable Execution], turning a Tier Three great demon into a pile of ashes on the spot. … After transmigrating to a parallel world, Wen Che discovers that impostors are everywhere. One out of every two people is a man-eating monster! While everyone else trembles in fear at the sight of an impostor, Wen Che awakens a System and the heaven-defying talent [Do Unto Others]. A single touch lets him copy the max-level divine skills of human elites for free, with no strings attached! And that’s when things take a ridiculous turn. The stunning, icy-cold female superior at the Special Affairs Bureau lifts his chin. “Be my dog, and I’ll give you a life of luxury.” Wen Che barks without a shred of self-respect, then casually copies his superior’s Catastrophe-class skill. From then on, Jiang’an City gains an urban legend that terrifies every impostor. By day, he rides his little electric scooter around delivering food. By night, he wields a Tang-style saber and flings around max-level divine skills. “Excuse me, could you move? Your impostor head is blocking my down payment on a Ferrari.”
