In the dark alley, stood Kahn as he was trying to comprehend exactly what happened. He hadn't even detected that he was poisoned through the wine he was drinking until the system notified him that he was poisoned.
And to top it off... the Poison was an extremely lethal one. If not for his Grandmaster rank Poison Immunity he got after absorbing the body of the legendary Somir during hunting days in the forest, Kahn would be either dead or on the verge of it in just a few hours already.
But thanks to that ability, all he felt was losing control over his nerves and balance of his body when he was riding inside the carriage. The poison itself was so potent that even his grandmaster rank immunity took some time to completely process and detoxify his body. Or else, he would've died a painful and pitiful death.
