"The only way to counter the Medusa poison is to weaken the poison in the body of a physically strong Alchemist. Ordinary humans do not have the adequate endurance and capability to do this. After I give Medusa to Aleksis, I will also take the poison and my body will automatically neutralize it. My blood vessels will take the poison to my heart where it will be neutralized. My blood will then contain the Medusa antidote, which can be given to Aleksis. Our blood type is a match. I could die if my heart is not able to neutralize the poison fast enough, but even if I die… you can still give my blood to her as the antidote."
Lauriel's face stayed flat when he was explaining the process to Caspar, while the latter looked shocked.
Caspar had expected something bad, but not THIS bad.
