Surgery
Just like that Sam settled in the Gambler's academy while White settled in the Zeus academy.
But Sam couldn't stay there for long. He had to leave the academy after checking in his dorm and go back to the inn where Stone is staying.
It is finally time to start the treatment and perform the soul surgery.
Sam entered the inn where the room is already prepared.
He made stone undress on a large surgical table specifically prepared for this. Sam then activated his vampire bloodline. His hair and eyes turned blood red with his fangs growing out. He bit his finger and started drawing some inscriptions with the blood on Stone's body.
After studying many necromancy techniques, he decided to merge a couple of them to properly perform this. These inscriptions are actually part of a soul binding technique. This will make sure that the soul is confined to the body.
