If Yun Yi went crazy then he would end up dying while in his sleep! Captain Lei did not want that, after what happened that night, Captain Lei had developed a newfound fear towards Yun Yi and his teeth.
Rong Wei also turned to look at Song Yan. The last thing he wanted was Yun Yi to go crazy like he did last night. That was a sight to remember and he did not want to face it ever again. Of course, Song Yan knew that these two men were scared because it was their first time facing a ghost. She smiled at the two and said, "There is no need to worry. Yun Yi is no longer possessed by the ghost. He is just a normal human now."
