(I'll update with a burst of energy once the wind has passed.)
There is a story in the Bible, where God decided to test Abraham, and said to him: "…Take your son, your only son Isaac, whom you love, and go to the land of Moriah. And offer him there as a burnt offering on one of the mountains that I will show you.”
After hearing God's instructions, Abraham was completely shocked, but he dared not defy God's will, and ultimately decided to do as God commanded.
Just as Abraham had made all his preparations and was about to mercilessly kill his own son, an angel called from heaven: "…Abraham, Abraham, do not lay your hand on the boy. For now I know that you fear God, because you have not withheld your son, your only son, from me."
In the Book of Zerubbabel, Michael once replied: "…I am the one who saved Isaac and mourned for him.”
Roy's power, 'Divine Right Hand', originates from this myth, and is the only one of Roy's Seven Powers that is related to healing.
As this power is only one of the powers, not a complete power, it therefore has numerous limitations.
It is not like Lady Aisa’s power, where she can unleash it freely as long as she possesses magical power. Roy's power can only be used once a day.
However, due to this limitation, its effect is extraordinarily powerful. Lady Aisa’s power can revive anyone as long as they have a breath left, but it is helpless against curses or negative states like Princess Alice's.
When used on others, Roy's power can transform the impossible into reality, healing any injury and removing all negative states, forming protection. When used on himself, it allows Roy to recover from any severe injury, even if he is close to death, allowing him to briefly ignore all injuries and return to his peak state. It will only be after the power’s duration that the injuries will resurface.
This can be considered an escape ability for dire situations.
Roy named this power - 'Isaac's Redemption'!
To use this power on others, only physical contact is necessary. The reason why Roy chose to use bodily fluid exchange is simply because he wanted to.
"Ugh…"
Princess Alice whimpered, her pale hand pushing against Roy trying to push him away, but as a vegetable lying on the bed, where could she find the strength? After struggling for a while and failing, she could only helplessly let go and allow Roy to claim what he wanted.
Erica and Lilliana stood beside her, completely astonished. They never expected Roy to do such a thing. They stood there blushing, flustered, and speechless. Lilliana, in a daze, started imagining some domineering CEO romance novel scenes in her head.
The scent of a man filled her senses, causing Princess Alice’s heart to race, her brain feeling dizzy from lack of oxygen. Besides Roy's scent, the most prominent sensation Alice felt was the unusual magical power flowing into her body.
This magical power was completely different from ordinary mana. Besides the difference in quality and quantity, it was forming a mysterious effect in a way Alice could not understand. She knew this was the power of a Slayer, a feat of mortals seizing power from the divine, an existence that is difficult for mortals to comprehend. Now, this power formed by magical power was rapidly improving Alice’s body.
Her weakened body, which was weakened due to excessive spiritual power, began to become flexible, as if rusted gears were refilled with oil, smoothly operating again.
Never before had Alice felt her heart beat so forcefully, never before had her mind been so clear. Her slender wrists finally had enough strength to push Roy away before she nearly suffocated.
"Huff…Huff…"
"Roy 'King', don't you find this too shameless?"
Alice reproached him with a blush of shame, her breathing ragged. She placed her hand on her chest and slowly began to regain her breath.
Then Alice was surprised to discover that her shout had a strong voice, completely different from her previous weak appearance as a critically ill patient.
Her limbs became full of strength. She could even feel her blood flowing rapidly through her body. Even her pale hands now had color.
Although she was still as anemic as a patient, much weaker than a normal person, overall, she had undergone a huge change from her previous near-death state. At the very least, she could now eat and drink like a normal person, and walk on the ground.
This was the first time Alice had felt the vibrant energy of life since she collapsed in bed six years ago.
Roy did not follow Alice's topic and replied, seemingly savoring the moment, as he squinted his eyes and smacked his lips: "...Very clumsy, it seems this is Princess Alice’s first time. I thought with Princess Alice's relationship with Alexander Gascoigne, you should have had intimate acts already."
Roy’s teasing words further angered Alice. She said disapprovingly: "...Please do not compare me to that troublesome fellow, Roy 'King'."
"Oh? Alice, you are called the 'White Princess', while that Gascoigne is called the 'Black Prince'. I thought you two were a match made in heaven."
Roy feigned surprise, but the surprise seemed fake, just a way of him teasing her.
"I am also helpless about this. But since everyone calls us that, there is nothing I can do to refute it… Besides, if I really had an intimate relationship with Alexander, then your previous actions would be equivalent to declaring war against him."
With strength in her body, Alice became more sharp-tongued.
"I don't care about declaring war against him. Besides, if you really had an intimate relationship with him, I might be even more excited now. As a Demon King, don't you have to steal the princess that someone loves, make the princess and her beloved despair?"
“…That Gascoigne, he is too cautious. So cautious that he is unique among the Slayers. Do you think he is nearby, watching, wondering if my actions are aimed at luring him out, then feeling painful envy that I can get Princess Alice’s first time?”
Roy said this, and even looked around, as if Alexander Gascoigne was hiding in some corner, afraid to come out.
"You are truly…"
Alice was somewhat amused. What could she say to someone so shameless.
Erica and Lilliana's expressions towards Roy also changed significantly.
‘Pervert!’
Alice muttered under her breath, then tried to keep her calm and said: "...Roy 'King', doing this without a girl's consent and forcing yourself on her will make her dislike you. Although some girls like being treated forcefully, I am not one of them."
"I don’t care whether you dislike me or like me, whether you are willing or unwilling. I am a Demon King, I run rampant on earth, I do as I please. Even if I declare you mine here, I want to start a harem in this modern world and collect beautiful girls of all kinds, people would not be surprised at all. Because this is my power!"
After pausing for a moment, Roy shrugged his shoulders: "...Alright, now that Princess Alice can move around, there is no reason for you to refuse me anymore. Your life has been drafted by me!"
