Mistake
After a day, Vincent managed to enhance one of the potions into +9 and tried it with the patients.
As expected, it did work perfectly and one potion was enough to cure three poisoned people. This news immediately attracted the few high-ranking nobles within the Arms City including those within the few Clans who had entered the city to protect their borders.
Apparently, the 40 or so patients within the infirmary weren't the only ones affected by the poison.
It was only because of the limited space, that the others had to remain under the care of their clan or sect.
At a certain courtyard not too far from the Blue Storm Castle.
"Quickly! Bring those infected by the poison to the Blue Storm Army's castle." A man in his forties ordered his subordinates as soon as he heard the report.
