Higashino Yuu never imagined that the "cognitive reconstruction" ability he awakened after traveling to Academy City would become the ultimate cheat for building a harem. Saying "You're a little attracted to me" to Misaka Mikoto makes the Railgun's cheeks turn red as ripe apples. Mummifying "You want to understand me" while locking eyes with Shokuhou Misaki makes the Tokiwadai Queen's remote control quietly aim at him. Even a saint like Kanzaki Kaori can blush at the mere suggestion of "Come see me tonight." From Judgment Officer Hatsuharu to ANBU TEM's Mugino, from the mage-minded Index to the one-eyed demon god Othinus... If he so chooses, rewriting the perceptions of girls and making them utterly devoted to him is a matter of thought. Higashino Yuu held his forehead, looking at the group of beautiful girls surrounding him, sighing with both helplessness and excitement, "I told you not to push... Okay, whoever kisses me first, I'll be theirs tonight." This is the story of a man who uses his powers to forcibly conquer every goddess in Academy City, turning his "harem" into a "settings manual"—after all, for him, making beautiful girls fall in love with him is easier than unscrewing a bottle cap. PS: This book is more about daily life, with more peach plots in the later stages. I'm not a fan of meticulous research or rigorous settings, so please don't criticize me if you mind.

"Yandere," "Girl Army," "Absolute Enslavement," "Villain," "Dual Heroines," "Vampires," "Apocalypse"

The obedient girl Su Mu in ordinary days has a rebellious personality and unusual sexual orientation, like a devilish, yandere little devil.

As the apocalypse descended, Su Mu, favored by the progenitor of the vampire clan, became a vampire demon princess, gaining vampire power and the psychic talent "Absolute Slavery".

Look down on my aloof and cool female disciplinary committee chairperson? Please play some "girl games" with me under my absolute subjugation!

Note: The female lead, Su Mu, is not a saint! She might do some inhuman and crazy things! Be prepared!

(P.S.: Due to the invasion of an alien god during the apocalypse, which caused a spacetime distortion, some familiar figures from the world of anime and manga may appear in the book. Don't be afraid of DNA mix-ups! "Anime and manga appearances will not affect the reading experience~")

Travel through a world invaded by disasters and awaken the sign-in system of all worlds.

He thought that signing in in this world and obtaining the power of a Ruler of Reason, which was enough for him to protect himself, would be great enough.

Unexpectedly, he was selected by the dimensional chat group and got the opportunity to sign in to other worlds!

[Ding! Congratulations to the host for signing in to the Genshin World and gaining the allegiance of the Heavenly Principle and the Four Shadows of Heaven.]

I originally wanted to head towards the end of the trees and the sea, but I found that I met countless beauties in the process.

Kasumi no Shi: "Tsk, what an unlovable leader!"

"You left a deep impression by being a hero saving a beautiful girl, but now you want to just walk away after you've been seduced?"

Eriri: "Damn it! I was here first, and the twin tails were supposed to increase attack speed! Why don't you come up and attack!"

Esdeath: "This man is stronger than me. I can't match him in terms of strength, but I must conquer him in other aspects!"

Lei Movie: "He saved his sister, if he wanted to..."

After traveling through time and space and becoming a Fader, he broke through the borderland and brought the petite Lani with him to the world of anime again. Here, the King of Elden began his new life.

Before today, Mo Li had considered himself quite successful as a time traveler! Despite his strange titles like "the company's hottest idol" and "honored guest of the Immortal Boat Alliance," Mo Li knew that everything he had achieved was entirely due to his own hard work! However... "System! Didn't you promise me the simulated universe was fake?" Mo Li trembled as he looked at the women, their eyes glowing red, gradually approaching him. [This...that...Hey!] As expected, the Maomao system was unreliable!

[Knowing joy is the unique right of intelligent creatures, and the joy system encourages the host to enjoy the joy of life! 】

Chen Ming, a security guard who has avoided 40 years of detours, suddenly found that he had awakened a system, and he grinned out loud.

With his many years of experience in reading novels, as long as the protagonist awakens the system, he will get a happy time like a dream...

Now, it is finally his turn to enjoy it.

Breaking the dimensional wall, facing the two-dimensional beautiful girls that he dared not dream of before, Chen Ming decided to give them a warm home...

Main world: "I am so happy!!!"

World No. 1: "The world's top assassin, reincarnated as a noble in another world"

World No. 2: "Reincarnation without a Job"

...

Until Chen Ming confirmed that he was invincible.

Me? Do whatever I want!

What, protect the world?

I want to protect my world!

And, I don't eat beef!

PS: Harem, steady, cool, not a saint, killing indiscriminately, blood flowing like a river.

PSS: Chen Ming is neither a good man nor a bad man. We generally call traditional men like him ancestor men!

Shen Muke, a travel enthusiast, transmigrated to another world. Although the journey wasn't pleasant, he still longed for a wonderful adventure in this new world. "But why [this land]?!" Thus, Shen Muke, with his love for travel, could only try his best to improve this world and create a better living environment.

Meng Yiyun was lying at home, playing Honkai Impact 3rd when his phone suddenly became hot. Just as he was concentrating on playing the game, the phone suddenly exploded. When he opened his eyes, he found himself in an alley and was very confused.

Meng Yiyun: "What's the point of this?"

Wait, what did you say? This is Changkong City!

It’s over, it’s over. I am a wife who likes Honkai Impact 3rd, but I didn’t say I want to travel through time.

Meng Yiyun was very scared, but just when he was almost in despair, the system finally appeared and gave him a glimmer of hope.

Herrscher of the Sky: Human, your instant noodles are gone again. I want to eat some.

Meng Yiyun: Ah, you ate all my instant noodles!

Hei Xi: Why did you bring me here again? I still need to accompany Xier.

Meng Yiyun: Well, I didn’t want to do that either. It’s my fault.

Mebius: Little white mouse, do you desire power?

Meng Yiyun: No desire, thank you

Mebius "No, you desire"

Meng Yiyun: Ah, help!

Mebius: "Haha, you can't escape from my grasp."

.........

(Slow heat + time travel + previous civilization + Mei Yi single female lead + main plot)

"Haha, I found you, Mei!"

Mei pouted in frustration: "Oh, you found it."

"I have 'Mei's radar', I can find you no matter where you hide~"

"I don't believe it unless we play another round!"

"Okay, let's play another round. This time I'll count and you hide."

......

"You said...you wouldn't lie to me..."

"You...big liar!"

She held the photo tightly in her hand, as if it was her only support.

"You said... you would come back... you said..."

"Achen...where are you..."

......

He promised everyone that he would bring back the girl who was as beautiful as a flying flower;

He promised everyone that he would try his best to leave more fire for mankind;

He promised everyone that no matter how much it cost—

Humanity...will definitely defeat the Honkai!

One careless move and he's transported to the Honkai Impact universe, gaining access to a game arena system, designed to bring smiles to the masses. Su Ze remains completely unfazed. "You guys fight it out, I'll provide the arena and maybe even skim some profits in the process." *Tianye Qingbian*: "Black Tower, clues are only 3 points, wanna buy?" *Resident Evil*: "Keqing, this is called RPG, one shot and even the Tyrant will kneel." *Monopoly*: "Ningguang, how about a remote-controlled dice for 1 point? Estelle next door already bought one!" And so, the two worlds drastically change their atmosphere. Kaeya: "2 points for the world, theWorld!!! Jingyuan, what are you going to do against me?!" Jingyuan: "Hmph... tail, save me." *Swarovski*: "Fierce gods and demons, I'm all you need." *God*: "Leave Clara." Clara: "Barsaka~~~~." *Hanabi*: "Let's fight! Let's fight!" *Silver Wolf*: "This is too intense!! Something feels off."
