Late at night on the day students returned to school, Li Wei cast a Disillusionment Charm on himself and left the Ravenclaw Common Room.
Hogwarts Castle was deserted and silent in the dead of night, with only the caretaker, Filch, making his rounds.
The cool Disillusionment Charm swept over his body, making Li Wei virtually nonexistent in Filch's eyes.

Li Wei suddenly felt that his actions sounded a little perverted!

Fortunately, his Patronus had not taken corporeal form. Otherwise, Myrtle would definitely have remembered it.
Just thinking about it made him want to complain:
He was clearly here to subdue the Basilisk and undertake the great cause
