Inside Liu Yi's cloak, she carried something. Although she understood the Poison Gu Art, she wasn't specialized in it.
Her main focus was on witchcraft, and the witchcraft from Dajin, just like Gu Art, required a medium.
For example, when Dong Huiying used Gu, she first needed Gu Refinement. Liu Yi's witchcraft, on the other hand, used a small wooden figure as the medium. This wooden figure was originally lifeless, but she carved it so vividly that it seemed alive, and she even infused it with blood from her tongue when it was made. This thing was like a mystical creature, possessing great powers and was quite sinister.
When Liu Yi arrived at Bai Xian's place, the wooden figure she carried in her arms, which she called the 'witch doll', gave a silent warning. This warning was undetectable to others, perceived only by Liu Yi who was adept in this craft.
She took Bai Xian's pulse and chatted with him casually, while discreetly observing the room where Bai Xian lived.
