The Delivery Guy from the Future

By chance, Qin Yi landed a strange job. The pay was surprisingly high, but the work was incredibly simple: he only had to stay in the shop every night. Qin Yi was very happy with the job, but when he asked his boss what he was supposed to do, the boss didn't give him a straight answer and simply said he'd find out when the time came. That day finally arrived. Someone brought him a parcel and told him to deliver it to someone in the past!!!
