This is a single-female-lead story, not a time-travel/invincible tale. Please stop bringing up the early camera thing! The protagonist isn't a time traveler! She's not that close to Misaka Mikoto at the beginning; that plot point will be resolved around chapter 170!

Accelerator: I am the strongest.

Touma Kamijou: Ever since the new neighbors moved in upstairs, I feel like there are more and more things happening around me.

Misaka Mikoto: I'll definitely beat him next time.

Shirai Kuroko: That guy who looks like a mountain, my dear older sister would never like him.

Teacher Xiaomeng: That child? He's really a headache.

Zero: I just want a peaceful campus life. I don't want to cause trouble, but trouble has come knocking on my door. Shouldn't I clean up this mess?

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.)

Fantasy + System + Danwu Dual Cultivation + Invincibility + Multiple Female Protagonists + Dog Licking

Qin Mu traveled through a fantasy world and was tied up and taken to the Holy Maiden Sect to do hard labor. When he saved enough money to redeem himself and was about to go down the mountain, he awakened the strongest dog-licking system. As long as he licked a woman who was stronger than himself, he could improve his strength.

Qin Mu secretly swore that he would lick the entire Holy Maiden Sect!

Senior Sister: Xiao Mumu, didn’t you say that you love me so much that you can’t help yourself?

Qin Mu: Sorry, I already have a leader.

Saint Lady Sect Leader: Qin Mu, from now on, you can only be mine!

Qin Mu: I can lick you, but I can't just lick you!

Licking people makes you stronger, it feels good...
