Baizhu had you stay after hours, just as a precaution as you had came in with a harsh headache. It was 1am, with no lights on in the room you were staying in.

There was a sound of glass breaking, so you got up to go and check it out. There were no lights on in the hall, except one with a figure under it, that you approached.

Baizhu was standing there, facing away from you with a broken syringe on the floor, and blood on the wall

"My my, what a mess..." He chuckled to himself.
