1602 Persistence

"Huh?"

Gredith turned to Kieran, searching for answers.

"It's poisoned," Kieran said.

With his near rank II Intuition and Musou level [Medicine and Medicinal Knowledge], he knew the envelope was poisoned the moment he laid eyes on it.

Since he had chosen to master poison in the mentioned skill, Kieran could even differentiate the poison inside: Fluoroacetamide mixed with green-and-black poison dart frog.

Judging from the poison level, one would not even have to bear a cut or a wound, a single touch on the skin would be lethal enough.

On top of that, the culprit was smart, a little contraption built with fish vesicles was placed inside. Whenever the envelope was torn open, the poison would be sprayed.

People were used to tearing envelopes in front of their chest and based on the height and angle, the content of the envelope would be facing the face, meaning the poison inside would surely reach the eyes, a weak spot.
