"Imperial Physician, can't a person who has been harmed by this kind of poison be tested with a silver needle?" Xie Pinggang asked.

"This thing isn't considered poison. After taking this silver ring powder, there will indeed be some symptoms, but this thing is mainly used for external application.

After applying it externally, there will be a certain degree of detoxification effect. However, this thing is still relatively rare, and there are few in circulation on the market..." Imperial Physician Wei explained.

"Now that Second Young Lady Dong is dead, how can we tell if she has taken the silver ring powder?" Xie Pinggang frowned, feeling a little worried.
