(No human female protagonist + no saintly qualities + system + master and servant + nurturing)

The Seven Deadly Sins represent the seven major demons in Hell. Angels and demons have been irreconcilable enemies since ancient times. Angels stand on the side of justice, while demons are condemned to evil. But in this world, only the victor reigns supreme; where is the distinction between justice and evil?

Weak humans can only exist in the middle, living humbly, and being used as toys for angels and demons to amuse themselves in their spare time.

Unexpectedly, he was transported to such a world.

I accidentally found a succubus scroll.

Awakening Demon Raising System!

Why is your intern succubus so cute?!

And what about your succubus strength? Is she really a weak succubus?

The girl from the Scarlet Devil Mansion meets a soul from another world, and the two souls merge into one, creating a new Flandre with a brain and reason.

After stepping onto another world called Terra, she looked up at the twin moons in the sky.

"Ugh, I want to go home so badly, I miss the desserts my sister makes for me..."

And so the girl embarked on her journey to find her way home.

[High-level martial arts + Evil sword immortal + Absolutely ruthless + Finally enter the Mutant Human Emperor Banner]

Qin Luo has traveled through time.

His parents were two of the twelve Martial Emperors of the Great Xia Dynasty, and their family was very famous in the Great Xia Dynasty, ranking among the top three.

He thought he could reach the pinnacle of life, with an incredibly lucky start.

Unexpectedly, as the memories merged, he discovered something was wrong.

In his parents' eyes, the battle in which he saved 200,000 people in the city was a failure because he didn't immediately identify himself as a member of the Qin family, and they accused him of not upholding the family's honor.

Going for a massage to improve blood circulation has become like going to a brothel?

Is your younger brother disrespectful, jealous, and deliberately distorting the facts?

Just then, the life choice system arrived.

He chose to become the Evil Sword Immortal, decisively severing ties with the Qin family and leaving.

After leaving the Qin family, he grew stronger and stronger, and his parents gradually began to regret it. His younger brother threatened suicide and knelt down to beg him to return to the family.

Qin Luo ignored it.

"Go ahead and kill me, I'll just watch you commit suicide quietly."

"I'm heartless? So what? You're too scared to commit suicide? Then I'll give you a hand! Go and reflect on your actions in my Human Emperor Realm!"

"Don't come any closer!"

"Hehehe..."

[No female lead] [Decisive and ruthless] [Cultivation and growth + genius story]

In a parallel world of advanced martial arts and modernity, Zuo Jian, with his dual souls united, possesses the talent of mirror clones, which allows him to create mirror clones in the mirror world as his cultivation level increases.

Something happened?

Let my mirror-world clones, cultivated over a year and a day, explain physics to you!

The mirror clones are very useful!

You can harvest and exchange them for experience points to improve your skill proficiency.

Alternatively, one could choose not to harvest the crops, but instead exchange them for time to exist, which would then be used to eliminate various troubles, both big and small, on his behalf.

"I have too many clones projected into my body, how do I use them up?"

"How about I build a factory..."

Soon, a 'drinkhouse' called the Evil God Cult was born...

O evil gods of other races who covet human flesh and souls! Don't be afraid, I'm really here to join you (slurp), not to harm you! (swallows)

(Not being the Nine-Tails' Jinchūriki + Hinata as the female lead + comedy + the protagonist has unique ideas and doesn't follow the usual formula)

He transmigrated into Naruto Uzumaki's body and possessed the legendary Super Saiyan bloodline!

This cheat is incredibly powerful, but it's also too easy to get out of control!

So I can't get angry, I have to keep my emotions in check, and be a villain who kills by destroying the spirit... The protagonist... whatever!

(Fantasy + Invincible + Protective + System Arrives Late + Sweet Romance + Daughter Raising + Decisive and Ruthless)

Xiao Ziling, who transmigrated to a fantasy world, had no awakening system or cheat codes. He relied entirely on his own efforts and opportunities to reach the supreme realm and become an existence that surpassed all immortals and gods.

Just as Xiao Ziling reached the pinnacle, the system belatedly arrived, informing him that he had a daughter who was now in imminent danger.

"So this is a legitimate sect! You think you can bully my daughter because she has no background?!"

"I'd like to see who dares to touch my daughter!"

Just as a group of self-proclaimed orthodox cultivators were about to judge Gu Ziyi, the entire sky was torn apart, and Xiao Ziling walked out of the void.

"Who dares to touch my daughter?"

"Daddy, they're bullying Ziyi."

With a single finger, the King of Hell calls out names, and whoever he points to dies!

This book is also known as "The System Arrives Late, I'm Already Invincible," "The Orthodox Ones Bully My Daughter? Suppress Them All!" and "My Cold Wife is Crying in My Arms."

[Two male leads, slow-burning Tom x Abraxas]

'The people I love are destined for misfortune, born from aphrodisiacs, despised beings, haunted by the most vicious curses... Even if I were to merely appear in your sight, I would feel as if I were defiling you, who are like a god... Therefore, I do not love you...'

But I love you...

"Bearing a bad reputation, or being feared and hated, is far better than having an empty heart, fearless of joy or sorrow..."

The introduction is inadequate; please read the main text if you are interested.

[Villain][Female Lead +][Fast-paced][Decisive and ruthless][Exhilarating][Guaranteed to be a hit]

You ask me what a villain is?

I'll do the things the protagonist doesn't dare to do!

The woman the protagonist dares not touch, I will touch!

Murder, robbery, swindling, and taking everything – that's what villains are all about!

......

Wang Ming's memories awaken, activating the Destiny Villain System.

With his left hand, he suppresses the chosen one of destiny; with his right hand, he manipulates the chosen heroine!

I've got my hands on the female lead, not even Jesus can stop me, I'm telling you!

I'll give you face and call you the Chosen One; otherwise, you're just leeks waiting to be harvested!

I'm not targeting any particular chosen one; what I mean is, all of you chosen ones are just my韭菜 (leeks/leeks) to be harvested!

[No female lead] [Slytherin] [Decisive and ruthless] [Snake]

Good people often have short lifespans.

If we're going to do it, let's be a scourge that wreaks havoc on the region!

He traveled to the Harry Potter world and became the last bloodline of the Prince family, a blood relative of Snape!

Alan Prince vowed never to be a good person in his life, but incidentally saved Snape from his tragic fate.

Some people say he's just a child with a bad temper.

Some people say he is a dark demon king who wreaks havoc in the region.

But many more people see him as the salvation of an ordinary wizarding family and a great man who led the magical world forward.

But all Allen wanted to say was that he was just an ordinary wizard, at most with a bad temper.

P.S.: What kind of normal person could a child raised by Snape be?! (Snape: He's slandering me!!!!)

The synopsis is weak, so I'll move the main text. There's a decent Harry Potter fanfiction as a base, so feel free to use it.
