Chapter 1285 - Chapter 962: Poison Doctor Unrivaled 23 (four thousand)

"This kind of poisonous insect is extremely vicious. Generally, masters use it to deal with their servants. They're afraid of being betrayed by their underlings, so they plant this kind of poisonous insect poison in them early on. The medicine is the master's own blood fused with a toxin called 'Poppy'. When poisoning, the servant must have a wound on their body. Only when the wound is bleeding can the master drip their own blood into the servant's wound, then have the servant ingest that opium poison. From then on, the poisonous insect poison takes shape."
