Qin Mu tidied up the herbs and matched them up. He nourished Old Ma's arm and Cripple's leg with medicine before buying some venomous insect powder of the south from the warehouse of the Imperial College.
This insect powder was made of incomparably tiny insects called Vermillion Beauty Venomous Insects. If a single insect was placed in front of a person, it was impossible to see with a naked eye, only with the third eye.
After the insects were dried and turned into powder, they would revive when in contact with blood.
Qin Mu asked for some fresh blood from Old Ma and Cripple and used it to dissolve the insect powder. When Vermillion Beauty Venomous Insects received the nourishment of fresh blood, they revived and made it seem as if the two goblets of fresh blood were alive.
