Good news: I've traveled through time, and now I have a beautiful, mature, and impressively shaped journalist mother who loves black stockings. I have an older sister who's a model with a slim waist, long legs, a delicate face, and 36D breasts who loves black stockings. I have a lively, cute, youthful, and beautiful younger sister who loves to wear a sailor suit and white stockings and is always clingy. I have a coquettish, charming, and teasing aunt who's a teacher in stunning black stockings. And before his death, my father left me a set of magical secrets that allow me to see the feelings and locations of women I've been involved with, as well as some very "interesting" abilities. Doesn't this start out familiar? Yes, the bad news is that the world he's in seems to be a city where you can easily become corrupted. Luckily, as a time traveler, he also has a hack for the ubiquitous system. So, I'll—Awesome! (This isn't fan fiction, because many heroines in this type of game start out badly, like the famous "Mou Chao" (a certain nest). To avoid any offence, I'm not going to make a fanfiction, just borrowing the setting.)

Zhuang Sen transmigrated to another world, a world where extraordinary bloodlines reign supreme, and the strong can even transform into dragons and titans, capable of taking on thousands single-handedly. But Zhuang Sen was dissatisfied. What were mere dragons compared to dragon girls? "Monster Girl Development System, activated!" he thought. Thus, a devout and holy nun transformed into the alluring and massive snake girl Lamia; a quiet young scholar became a languid and seductive vampire girl; a cunning and shrewish little imp sister became the charming and adorable Happy; a haughty princess became a red dragon girl… From weak slime girls to powerful dragon girls, from holy angels to bewitching demon girls, wherever Zhuang Sen's territory expanded, monster girls proliferated. "What? You say low-level monster girls are too weak, their bloodlines limiting them from ever becoming stronger?" "Simple," Zhuang Sen said, "I'll help them evolve!" With that, Zhuang Sen grabbed a monster girl, and she instantly evolved. And as the light of evolution faded, another hunter joined the hunt. Zhuang Sen, only fit for the strong! Years later, the legendary King of Endurance, the Father of a Hundred Races, and the King of Kings, Zhuang Sen, looked at the monster girls scattered throughout the world and uttered his final words: "Quack, don't mess with it!"

In the dead of night, Xiao Xia bumped into the school beauty.

If it were anyone else, they would definitely be excited to introduce themselves to the school beauty at this moment, and some might even offer to take her home, trying to leave a good impression on her.

But Xiao Xia's choice was completely different from others.

Xiao Xia chose to... perform a breakdance right there in front of the school beauty!

For no other reason than that Xiao Xia's system is too abstract!

Choose!

1. Perform a breakdance in front of the school beauty;

2. Corner the school beauty against the wall and yell at her to take off her clothes.

When Xiao Xia was approached by a delinquent girl.

Choose!

1. Immediately kneel down, kowtow, and beg for mercy;

2. Immediately hug the delinquent girl and whisper in her ear: "Because I like you, I want to get your attention."

When Xiao Xia was paired with a lively and cheerful sports girl in physical education class.

Choose!

1. Carrying the dark-skinned girl on his back, he ran a full lap around the playground;

2. He asked the dark-skinned girl: "May I smell your socks?"

Xiao Xia: You damn system, give me back the life you've ruined!

Wait, why am I surrounded by beautiful girls?

This book is also known as "The Naïve and Sweet School Beauty Wants to Be My Friends," "The Athletic Girl's First Love for Me," "The Delinquent Girl's Intentions Are Hard to Tell," "My Online Game Friend Is Actually a Legal Loli," and "My Childhood Friend from Abroad Came to Find Me."

When people are in their third year of high school, they are given a mission by heaven, and they will live forever?

[Your Majesty, a temptress in troubled times is trying to sow discord between you and Prime Minister Wang. She appears gentle, but in reality she is a manipulative and malicious woman. If you listen to her slander and ignore the principles of state, the dynasty will fall.]

Xu Yan looked at the head teacher in front of him and Bai Yueguang sitting at the table in front of him and fell into deep thought.

Going to class = going to court?

Laoban = Prime Minister?

Is Bai Yueguang a temptress in troubled times? The contrast is a bit shocking?

Whose system is so crazy?

…

But gradually, Xu Yan discovered something was wrong.

The cute childhood sweetheart is a yandere, the aloof goddess suffers from a chuunibyou, and the new neighbor sister actually loves to stalk...

The system is a little crazy, but it's right...

[Your Majesty, you and the Saint have successfully achieved "Double Shame", Literary Strength +1, Military Strength +1.]

oh?

…

"Damn magical girl, don't underestimate the bonds between us villains!" Dawn said, glancing at his companions.

The organization's leader is actually a magical girl who traveled back from the future, and she's trying to persuade him to surrender.

The taciturn girl that the eldest brother took in has now been recognized and transformed into a magical girl;

His buddy, who called him brother, wasn't a magical girl, but this buddy had a female brother who had been whitewashed into a magical girl, so he was whitewashed too;

"Come on, it's your turn to get cleaned up!" Looking at the kind-faced crowd, he had no choice but to say:

"Quack, don't come near me!"
