Necromancer Forced to Save the World

Qiao Xi, the world's most powerful legendary mage in his previous life, became a food deliveryman in this life. Forget it, days have to pass, but the world said to Josie: "Hell mode is about to start, come on, dear!" Josie:? ? ? Wait, why did the person I hated the most in my previous life also appear? And there is such a clear contrast? When the world fell into chaos, and humans mutated into monsters that threatened all life, a necromancer who wanted to just lie down was forced to return to his old profession. Josie: I'm here to deliver the food and kill some monsters on the way. Tai Lun: The company's profits are hundreds of millions per second. After defeating the monsters, the meeting will continue. Motto: Please believe in science
