The Shiyi that Yao Xuanhang mentioned is his childhood friend, Su Shiyi.
They live right next door; their houses are close by.
So, the two of them have always had a close relationship.
Yao Xuanhang had saved quite a few photos of the two of them, or group pictures involving them.
At Jiangli's request, he found a recent photo of him with Su Shiyi.
Jiangli took the phone, looked at the photo and said, "Bright eyes, open facial features, a kind heart, she's not a bad person, she probably didn't mean to harm you."
Jiangli handed the phone back to Yao Xuanhang, speculating, "I suspect someone exploited her concern for you."
Yao Xuanhang's eyes suddenly darkened, "Could it be Tao Yicheng again?"
"It's hard to say," Jiangli replied. "But, having such an object in your bedroom, affecting your sleep over time, and attracting Yin Energy, none of it is good for you. The ghost wall that you encountered in the middle of the night, it's very likely the doing of this object."
