My name is Chen Mo, a delivery boy from all over the world who has traveled to a strange world. The system asked me to deliver masks to the slit girl, draw smiling faces to the faceless children, and find relief for the drowned souls. Others rely on killing and purification to gain good reviews, but I rely on "emotional delivery" to gain bonds. Until I accidentally used the master key to open the backend of the world - it turns out that all customers and riders are "emotional batteries" cultivated by the system. When the light blade of my colleague was pointed at me, the will of the system began to obliterate me. I faced the live broadcast camera and raised the key made of countless customers' return gifts: "Today's last order, I will deliver 'freedom'."
