"Indeed," Nanli nodded, "This person must have used some kind of talisman. I couldn't tell that Second Aunt had already switched bodies, but living in the Marsquis Mansion will inevitably reveal flaws."
At this moment, Chu Shuo chimed in, "Yes, yes, when we visited Seventh Sister earlier, her clothes were torn, yet no one noticed. Sixth Sister and I found it quite strange."
You see, the Tian family is known for their attentiveness and care, how could they not have noticed even a tear in Chu Nanying's clothes? They immediately grew suspicious.
Later, this "Tian" tested her with tea, and even organized a family banquet, which only heightened their suspicions.
Nanli had warned Chu Shuo and even gave him the newly created poison-detecting talisman, which led to the scene just now.
However, this "Tian" is skilled in the Dao arts and nearly caught them off guard.
It seems likely that she is the female Daoist who saved Third Brother that day.
