[Anti-dote of poisons]
~ Most of the Royals including Kaiser used to go through this experiment to strengthen their immunity and build a natural antidote inside their body to fight against any kind of deadly poisons.
The process of building this antidote in their body was indeed unbearable and excruciatingly painful. They had to intake poisons again and again in a huge amounts while healing themselves with their mana. The process was so complicated and scary that only royals with high confidence and strength would agree to this life-threatening experiment.
However, in Fintan, only Kaiser and Samuel agreed with it. Though Aylin didn't get the chance to experience it, her brother, the late Crown Prince also went through that difficult situation.
