In theory, there were only two days left... Yang Xiao didn't know whether May 14th counted, if it did, at most, there were only three days.
After three days, the female ghost would begin a massacre, and everyone in the hospital would die. As for his team... Yang Xiao calculated that if one person died each day, there would be at most one person left by then, which was no different from being wiped out.
Upon learning that May 14th was their death date, Captain Zhou instead felt relieved. During this period, they were constantly on edge because they didn't know the deadline for the task, nor what they were supposed to do, and how to go about it.
Captain Zhou told Yang Xiao that the six of them were night shift medical staff in this hospital and that they had to stay in the hospital's dormitory during the day and rest, without leaving. Every night, two people were on duty, but they had to choose between the first, second, and third floors, with each person on a different floor.
