Selma Payne's POV:
The experiment results showed that intelligence's influence was almost zero. The tenacity of the soul determined the success or failure of mental control. Crows with psychic abilities could resist for longer than powerful tigers, and their threshold was higher. However, all souls would face the same end-madness once the threshold was broken.
Yes, there was only one result - going crazy. No matter how serious it was, it couldn't directly cause death unless the experimental subject committed suicide in an extreme state of madness.
Going crazy but not dying, how familiar did that sound?
I was almost certain that the murderer must be from the Evaria Family and one of the descendants of that illegitimate child.
His age did not match. The murderer was his blood-related brother, sister, or even one or several biological parents.
