Doomsday Wasteland: Rely on the System to Redeem Me and Become the King

On the 30th day of the zombie outbreak, there was a strange vortex in my head——[Everything Exchange System] It absorbs materials by touching it, and everything can be recycled! ! Buy buy buy buy buy! ! ! In this world, even the air is filled with death—— ✅ Humans have mutated into rotting zombies, animals have evolved bloodthirsty fangs, and living human brains are buried under plant roots! ✅ And I, a social nerd, have awakened to the [All Things Exchange System]: the cans I touched instantly turn into gold coins, and Gatling appears in the system mall! Ta-ta-ta-ta-ta. . . . . . ✅ When the survivors were chewing tree bark, I was buying self-heating hot pot in the mall; when the superpowers were fighting zombies hand-to-hand, I was sniping at the heads of mutated giant lizards through the bulletproof glass! ⚠But the system hides a fatal price—— Every time I exchange supplies, my blood vessels will have more jade lines. The whisper of the ancient god echoed in my ears: "When your heart crystallizes, that's when I will return to the world..." Now, I am holding an AK-47 in my left hand to shoot at the zombies, and the fingertips of my right hand are flowing with cursed fluorescence. "Want bread? Give me the crystal core in exchange." "Can't afford weapons? Your teammates' lives will also be at stake." ——This is the craziest doomsday supermarket, and I am the only profiteer who dares to bargain with the gods. "Warm reminder: Our store does not accept credit, but we accept using your soul to prepay for the next life."
