Do you know that legend about the freight elevator in the old building? If you press and hold the "1" floor at 2:05 in the morning, it will take you to a place that shouldn't exist. Delivery boy Zhang Wei decided to take a gamble in order not to run out of time. He entered the -3 floor and "saved" the order that was supposed to be delivered into a strange existence. When he returned to reality, he found that the records on his mobile phone were blank, as if nothing had ever happened. But this was just the beginning... Was what he "saved" really just a takeaway?
