Walking out of the lesson, Beatrice began swiftly walking back to her room before sitting on her bed.
"Let's do this," mumbled Beatrice as she opened up the first book on mind manipulation that Mr. Errol had given her.
As soon as she began reading it, Beatrice began becoming lost inside of the book as she swiftly plowed through it.
...
One month later,
Looking at the white-haired mage that had locked him up onto a bed, Christian tried his best to resist.
"Let me go!" shouted Christian as he struggled against the restraints placed on an a brand-new bed.
Suddenly, the white-haired mage appeared behind Cristian before placing two of her fingers on his forehead, causing Christian to begin thrashing about even more, but as time passed, his resistance began decreasing.
Seeing the subject begin resisting less, Beatrice pressed on, increasing the amount of mana she sent into his head.
"Be good, don't cause trouble," said Beatrice, her voice changing into that of an older woman.
It seemed like hearing his mother's voice pushed Christian over the edge, as his resistance began decreasing dramatically, allowing Beatrice to send more and more dark mana into his head.
As she sent mana into him, elemental energy suddenly began gathering around Beatrice, as her mana pool was not yet large enough Beatrice, had to refine more mana while taking control of Christian.
After over an hour of doing this, repeatedly sending in her mana into Christian's head and slowly morphing him to her liking, Beatrice had already begun shaking, right now both her mind and body were extremely tired.
Suddenly, Beatrice took out a potion from the inside of her room before drinking it.
Thinking about how the potion had cost her ten elemental stones, Beatrice felt extremely uncomfortable, but still, after drinking it, all of Beatrice's fatigue suddenly disappeared, being replaced by a boundless vigor.
...
Knowing his mother was behind him, a smile appeared on Christian's face.
Ever since he was five years, Christian's mother had been the one to raise him and his sister alone, every day, she would work from the earliest moments of the morning to the dead of night.
Thinking about his mother's course but warm and gentle hands, Christian suddenly began shaking, but as that happened, a dark aura suddenly flew into his head.
"Mother doesn't need to work anymore, her hands are as fine as silk," mumbled Christian as his previous thoughts were forcefully interrupted.
...
Looking at the man sleeping on the table, Beatrice couldn't help but breath a sigh of relief.
"That was way too close, I almost lost control of him," mumbled Beatrice as she looked at the sleeping Christian with a smile on her face.
Suddenly, Beatrice walked up to her bed before regenerating her mana for around thirty minutes before walking back up into the experiment room.
The moment Beatrice walked into the room, Christian, who was previously asleep on the bed suddenly opened his eyes, but oddly enough, he did not say anything nor did he move.
After taking a good look at him, Beatrice walked up to the bed before removing the restraints on him.
"Christian, get up," said Beatrice as she looked at the bed in front of her.
"Yes mother," said Christian as he suddenly got up from the bed.
"That's no good, you can call me mistress, but not after every sentence I say," said Beatrice as she sat down on a chair in a corner of the room.
"Yes mistress," said Christian, standing completely still right in front of the bed.
"Catch," said Beatrice as she suddenly threw a knife at Christian.
With extreme dexterity, Christian easily caught the knife flying towards him, causing Beatrice to smile.
"Even though it was more difficult, it seems like controlling a Grand Knight was worth it," thought Beatrice before issuing her next command.
"Commit suicide," said Beatrice as she looked at Christian with a smile on her face.
Suddenly, Christian took the knife before ruthlessly stabbing it at his own neck with no hesitation, but thankfully for him, the knife suddenly stopped after just touching his neck, and at the same time, did not touch any major blood vessels.
"It looks like both methods of control work," mumbled Beatrice as she easily controlled Christian's body, stopping his suicide attempt.
After testing some more commands, Beatrice commanded Christian to sit down on the bed.
After making sure that she had everything on hand, Beatrice took out a giant syringe before injecting enough anesthetic to kill an elephant inside of Christian.
"Just in case," mumbled Beatrice as she carefully picked up a tiny bomb that she had bought for twenty elemental stones.
Even though it might not seem like much, the reason Beatrice could afford to do this was that she had taken out ten elemental stones out of her savings, as Christian was Beatrice's second attempt, she had to spend a total of forty elemental stones on two Grand Knight's, together with the bomb and the potion, the cost of this procedure has reached seventy elemental stones.
As such, for the entirety of the next month, Beatrice would have to live a frugal lifestyle, as she did not have even one elemental stone to her name other than her savings.
...
Picking up the needle, Beatrice took in a deep breath before slowly beginning to stitch the left part of Christian's chest back together, having already implanted the bomb inside of it.
Slowly but surely, little by little, the hole in Christian's chest slowly became smaller and smaller, eventually being completely closed.
"Thankfully he's a Grand Knight," thought Beatrice, unsure whether she could conduct such a surgery on someone with less vitality with both her current skills and equipment.
Suddenly, Christian began slightly moving, causing an already prepared needle to float into Beatrice's hands before she injected it into him.
"That should be enough anesthetic to keep him sleeping for a while," thought Beatrice before beginning to clean up the blood present on her tools, and after that, she spent around ten minutes of cleaning up her tools.
After finishing, Beatrice took out a small piece of paper from her robe before writing something on it and placing it next to the tools.
'Need to be sterilized'
As for the effect of not properly sterilizing your tools, Beatrice had seen it first hand at her estate back home, after making such a mistake once, Beatrice did not do it a second time.
