He slowly closed the door, with such care that no sound was made. He didn't leave but instead stood silently outside the bathroom door waiting. Sure enough, after about five seconds, the eerie dripping sound started up again.
"Drip-drop."
"Drip-drop."
...
Yang Xiao took a deep breath and cracked the door open again; the dripping sound stopped as if everything before had been an illusion. But Yang Xiao didn't think so; he was certain this was ghostly activity.
He slowly raised the Ghost Lantern in his hand, pouring a considerable amount of spiritual power into it, and then placed it by the gap in the door, shining it inside. As the green light entered, the scene inside turned eerie. The previously neat walls were now decrepit, covered with black mold, and the floor of the bathroom was muddy as if it had been corroded by some kind of acid. At the same time, the bathroom door was pushed by a strange force and slammed shut.
