Although writing to communicate was a bit troublesome, it was better than being unable to communicate at all. Situ Shuangshuang didn't feel like asking them one by one, so she let the three girls write down everything they knew about the incident, including its cause and effect, for her to read.
Because Situ Shuangshuang had previously demonstrated her skills, and the three girls had seen her effortlessly deal with the fierce ghost that had scared them out of their wits, they showed no objection to Situ Shuangshuang's decision. They immediately sat down on the bench and started writing.
The girls exchanged ideas as they wrote quickly, and soon the entire process of the incident was clearly documented. The three girls even organized everything in a logical order, then handed it to Situ Shuangshuang like students handing in homework!
