Meituan Heroes

"What the hell is Meituan doing? I ordered a bacon pizza, why did a weird machete come to me?" "After you sign for the knife I sent you, you will become my chosen hero and you must help me conquer demons and slay demons!" "Hero? What kind of hero? I'm just a poor courier boy. I'm not a Maoshan Taoist priest. I don't know how to conquer demons and slay demons at all." "Meituan Tongtian, I have purchased other heroes to help you." "Who are you anyway?" "I am your destiny!"
