Dormitory Rules:

Lights must be turned off at 11 PM.

After lights are turned off, electronic devices cannot be used, otherwise the dormitory supervisor will immediately confiscate them.

After 12 AM, if you hear someone playing the suona in the corridor, ignore it.

Considering the above three rules, according to the plan, we decided to take action before 12 AM.

After all, we still have two formidable opponents to deal with.

As the lights were turned off at 11 PM, the dormitory became pitch black, and the final battle was about to begin.

The four of us gathered together, waiting quietly for the moment of the decisive battle.
