When you press the alarm clock once and pick up the stones on the ground, you will be prompted to complete the task. You can't hand it in at this time. If you hand it in, you can't brush D film indefinitely. At this time, you can press Q to open the task window, and then choose to give up the task. This will prevent you from accidentally handing in the D-film next time you pass by. Please give points if you are satisfied. Thank you.
