I Deliver Food in the Underworld

My name is Yunyao, and I live in a remote town in the northwest. I just graduated from college and my family was in urgent need of money, so I had to find a part-time job delivering food. Not long ago, I grabbed a big order with a commission of 500 yuan. When I was feeling complacent, my colleagues gave me strange looks. I just thought they were jealous until I saw rows of tombstones at the delivery address. Before I could get scared, I heard the voice of my ex-boyfriend who I hadn't seen for several years coming from behind.
