Zhen Li Nai was originally sleeping soundly in her room when suddenly a blurry figure appeared in her dream.
"Wake up, Zhen Li Nai, your sister is in danger."
The person said these words, leaving the girl feeling somewhat bewildered.
"Who are you? What nonsense are you spouting? My sister is fine, how could she be in danger?"
To this, Lin Mu casually said, "I am merely a demon who occasionally plays in the human world. Your sister's room has currently been invaded by your new stepfather, and that pervert is about to bully her."
"If you want to be saved, call my name. Remember, my name is Lin Mu."
Zhen Li Nai heard this and suddenly woke up with a start.
She didn't bother to ponder the truth of the dream, quickly got up, put on her slippers, and left the room.
Then, she saw Akizuki Xiao San entering her sister's room.
Without thinking, she rushed over and saw him stripped down to his underwear, while her sister, Akiyama Airi, was sitting on the ground, crying pitifully and unable to move.
Moreover, her sister's cheeks were flushed, a very abnormal kind of redness.
"Wuwu, Big Sister, save Airi! This scum wants to do that kind of thing to Airi… Airi told you he had ill intentions a long time ago, but you and Mom didn't believe Airi!"
"Shut up, Airi!" Akizuki Xiao San couldn't help but curse, quickly pulled out a spray, and sprayed it at Zhen Li Nai, who couldn't dodge in time.
Immediately, Zhen Li Nai followed in Airi's footsteps.
Airi was also crying, frustrated by her sister's slow reaction.
Lin Mu, who had been in control of the situation all along, was also a bit speechless. He had already warned her, yet she still fell for it.
Indeed, the female leads in adult comics are just weak.
Akizuki Xiao San looked at Zhen Li Nai, who was sitting on the ground in a panic, unable to move, her face flushed, and he couldn't help but laugh.
"Zhen Li Nai, since you're here, join us."
"However, Daddy still wants to discipline naughty Airi first."
Akizuki Xiao San said, walking over and reaching out his hand towards Airi.
In her panic, Zhen Li Nai suddenly remembered the demon's voice from her dream, and by some strange impulse, she shouted, "Lin Mu! Mr. Demon, please save Airi and me!"
"Then, as you wish!"
A purple light suddenly burst forth. Before Akizuki Xiao San could react, he was struck by a force and sent flying, crashing heavily into the wall.
Then, a ball of flames instantly engulfed him.
Akizuki Xiao San's evil display was over, and Lin Mu had achieved his goal of a demon saving a beauty. He naturally wouldn't keep this guy around to be disgusting.
Every piece of trash has a reason for existence, and in Lin Mu's eyes, Akizuki Xiao San was merely a tool to highlight his glorious demon image.
Zhen Li Nai and Airi stared blankly at Lin Mu, who had appeared, noticing his handsome face and the charming wicked smile at the corner of his lips.
The two girls' already flushed faces couldn't help but grow even hotter.
"Ugh, Big Sister…who is he! He just appeared like this…Ugh, never mind, (bdab) at least he's so handsome…Come on, Airi can't take it anymore."
Before Zhen Li Nai could react, Akiyama Airi used all her strength to hug Lin Mu's leg, looking at him with seductive eyes.
Lin Mu calmly embraced the two girls and closed the door.
Now, he was the demon who had appeared to fulfill Zhen Li Nai's wish.
Don't forget the power of that prayer.
Through guidance, he proved the possibility of personally orchestrating events.
And he and Zhen Li Nai had also initially reached a verbal agreement.
Next, it was time to collect his reward.
"Wuwu…Big Sister…Airi…Airi feels so uncomfortable, please, big handsome brother, hug Airi."
Akizuki Xiao San's potion was truly strange; it actually aroused girls' desires.
Perhaps it was precisely because of this potion that he became a sinful soul.
If this potion were to become widespread, then girls in this world would definitely be persecuted.
"Airi…how can a girl say such shameless things? Ugh…"
Zhen Li Nai, with a flushed face, tried to educate her sister, but her own body also began to feel strange, and she suddenly couldn't speak.
Lin Mu was not in a hurry; he just quietly held the two girls.
"I am a demon, Miss Zhen Li Nai. I appeared for you and have resolved your crisis. So, now it's time to collect my reward."
"Demons don't do business at a loss, you know. Hmm, other matters, the rewards must be calculated separately."
Zhen Li Nai's eyes widened, staring at him with watery eyes, "How can you be like this? I thought you were a good person."
"I am a demon, I said so from the beginning. So, Zhen Li Nai, and Miss Airi. What do you wish to gain from me?"
Lin Mu smiled gently, captivating both girls.
Although he was a demon, he was still much better than that scum who wanted to lay hands on his own daughters.
The potion was taking effect, and Airi was the first to succumb.
She actively burrowed into Lin Mu's arms, clumsily tugging at his clothes.
"Anything is fine, big brother, Airi will agree to anything…Ugh, Airi feels so uncomfortable, please, help Airi…okay?"
Lin Mu showed a hint of interest, but his gaze was fixed on Zhen Li Nai, who had lowered her head, her face flushed.
"Wuwu, Big Sister…save Airi…Good Big Sister…wuwu…"
"Wuwu, Airi…Big Sister will save you…"
The two beautiful sisters, bound by deep affection, ultimately could not resist their inner desires and succumbed to the cunning demon.
Lin Mu received the response, and the contract was instantly formed.
Demon Kin +2!
"Alright, as you wish. Your wishes have been truly received by me."
Next.
Let's satisfy them.
As a demon, one must adhere to the spirit of the contract.
If you promise, you must deliver.
And so, a dreamlike scene naturally unfolded.
Zhen Li Nai felt as if she were dreaming.
Lin Mu's gentleness, his handsome appearance, and his skilled actions guided this innocent girl.
And compared to the shy Zhen Li Nai, Airi was even more uninhibited.
There is no end to learning; Lin Mu felt that the Akizuki sisters still had much to learn.
He gave Airi and Zhen Li Nai a little guidance.
After leaving behind the demon's magic seed, he dematerialized and left.
As for how to deal with Akizuki Xiao San's disappearance, they could talk about it tomorrow.
Lin Mu returned to his room, took a shower, and then went back to bed, gently embracing Shiina Mahiru, enjoying the scent of her body, and falling peacefully asleep.
He hadn't even had time to check the abilities the two new familiars brought him.
… … …
The next morning.
When Lin Mu woke up, he noticed that his magic power had increased again.
The attribute panel had also changed.
[Demon Cultivation Panel]
[Player: Lin Mu (Unique Contract Demon)]
[Current Kin: Shiina Mahiru, Asada Shino, Yukino Shitayuki, Yukino Yukinoshita (not fully devoted, no additional abilities), Akiyama Airi, Zhen Li Nai.]
[Demon Abilities: Super Recovery, Guaranteed Hit, Damage Absorption Transfer, Damage Stacking, Left and Right Hand Dual Casting.]
[Demon Authority: Contract (Innate Authority, once a familiar is contracted, the soul is immortal and cannot be unbound), Judgment Flame (increases in power with the number of familiars), Lord of Magic (with an increase in the number of familiars, there is a chance to acquire new magic.)]
Seeing this, Lin Mu gained a new understanding of his abilities.
Second Miss Yukinoshita was already his familiar, after all, during their first formal meeting, she said she would do anything for her sister, which was tantamount to acknowledging that she belonged to him.
However, because there was no mutual understanding like with Yukino Shitayuki, Asada Shino, and Mahiru, he still couldn't gain the power that Second Miss Yukinoshita brought.
And the remaining 'Damage Stacking' was an ability brought by Airi.
Dual Casting was an ability brought by Zhen Li Nai.
The so-called left and right hand dual casting means he can simultaneously use two different spells, which is also a very powerful ability.
Moreover, this casting is not limited to magic; in the future, if he has other abilities, he can also use two abilities simultaneously.
For example, using two ultimate moves at the same time.
Finally, Demon Authority.
This was an innate ability of his soul; as the number of familiars increased, his innate abilities would become stronger and stronger, even evolving into new authorities.
As the saying goes, Dao gives birth to one, one gives birth to two, two gives birth to three, and three gives birth to all things.
His contract authority gave him infinite possibilities.
And the authority of the magician allowed him to occasionally gain insights, thereby learning new magic.
For example, the magic power transformation, the teleportation magic that instantly reached a familiar's side, was something he had realized.
He didn't know when he would gain insights; it was just a sudden flash of inspiration, and he would acquire such a skill.
And when contracting new familiars, it was most likely to gain some insight.
All of this was telling him that if he wanted to become stronger, he had to work hard to contract familiars.
The more beautiful girl familiars, the better!
