[You may close your eyes to wash your hair inside the Gymnasium, but if you do so, please inform the Athlete Student beforehand so he can ensure he is beside you. While washing your hair, do not open your eyes, no matter what abnormalities you sense. Tell yourself that you are washing your hair in the Shower Area. After you finish washing and drying your hair, confirm the situation with the Athlete Student before opening your eyes.]
"'Washing your hair with your eyes closed'... the accident probably happened during that part..."
The Notice Board did not say an Athlete Student had to be beside you when you showered, which meant that if you were only showering, having someone keep watch was not strictly necessary.
So Li Kai must have been washing his hair at the time.
"In other words, he opened his eyes while washing his hair... that must have been because he heard Yan Bujiao fighting the Green Apron Chef, made a mistake in his panic, and got himself into trouble too..."
By now, Lin Yi had worked out almost everything except the details. The only things he did not know were the details of Yan Bujiao's fight and what Li Kai had experienced after breaking the rules that had led to the appearance of the Impersonator Li Kai.
Moreover, the Impersonator Li Kai had remained motionless all this time and seemed fairly intelligent.
"Could Impersonator Athlete Students really only turn violent after leading someone out of the experience area?"
"Or has it just not reached the point of showing its true colors yet?"
If Lin Yi had stumbled across this by chance, he might indeed have speculated along those lines. But he could not forget that Boss had specifically called the Impersonator Li Kai over to keep watch
