[This is a lighthearted story; the protagonist has no morals or limits.]

Having transmigrated to the Harry Potter world, Charlie White is bound to the [Tyrant System].

By engaging in tyrannical behavior, you can earn Tyrannical Points and draw prizes infinitely!

While Hermione was studying her textbooks in the library.

[Ding! His Majesty's sleeping posture in class is practically a reincarnation of Hu Hai, perfectly embodying the behavior of a tyrannical ruler who "neglects state affairs"! Reward: Tyrannical Ruler Points +100!]

While Harry and Ron were training hard for Quidditch.

[Ding! His Majesty has been extravagant, purchasing all the desserts in Diagon Alley, in line with the behavior of a "tyrannical and hedonistic" ruler! Reward: Tyrant Points +500!]

Charlie casually did a ten-pull!

[Congratulations, Your Majesty, on obtaining: Animagus (Selectable Form)! +1 Free Talent Point, +1000 Proficiency in Fiendfire...]

Dumbledore: "Mr. White is the most gifted student I've ever seen, but unfortunately he just doesn't like to study..."

Voldemort: "Why? He learned the dark magic I painstakingly studied just by yawning?!"

Charlie lay on the sofa and sighed helplessly, "I don't want to either, but the system is giving me too much!"

[Infinite flow + self-created dungeon world + superpowered strategic combat + single female protagonist + apocalyptic start]

Demons in hell bestow power upon humanity in the boundless darkness, but the acquisition of any power comes at a price.

If you want to wear the crown, you must bear its weight! Gain inevitably comes with loss! If you are willing to pay the price, you will receive any power bestowed upon you by the devil!

As the fourth child of the Shinomiya family, I began living independently. Every day, I woke up in the dark closet, went to my bed, and took out a dummy, placing it under the bed. Then I checked the blades in the soles of my shoes to see if they were sharp, cleaned the potassium cyanide particles from my waistband, checked the prohibited words on my clothes, and made sure the miniature surveillance devices were working properly. I placed a bayonet in a book, and a submachine gun and bombs in my backpack. Completed, with a smile, I headed towards Soubu High School. As a normal high school student, I greeted a beautiful day. As a normal high school student, aren't the things I have normal?

Nangong Xiao: "I know more about this other world than anyone else." Asuna: "..." Nangong Xiao: "I'm not cheating, really, why are you looking at me like that?" Kasumi Utako: "..." Nangong Xiao: "Who says a cruel other world can't have a normal daily life?" Maple's eyes lit up: "!!" Nangong Xiao: "War is always the last resort. If you play it like a normal card, things will get very..." Shizuka: "Shut up! You're the main DPS, just focus on outputting damage!!" Nangong Xiao: "Ah, oh, coming right now..."

After being transported to another world, Mizusaki Yuuma looked at the newly released "Love Metronome" and realized it was a sweet slice-of-life romance anime. However, he encountered a girl collecting Clow Cards, a pile of scrap metal collecting the Peace Star, and a Sherlock Holmes from the Heisei era. He also occasionally heard urban legends about Tomie. Fortunately, his Yorozuya (Odd Jobs Shop) always attracted strange customers who traded things from other worlds with him. There was the Battlefield Rose from the ninja world, a rebellious girl from the world of navigation, a fox spirit from Valoran, and a girl visited by eight million warriors. Kasumigaoka Utaha: Hey, you have to take responsibility! Kinomoto Sakura: My brother is so nice, he helps me collect Clow Cards. Irelia: Grandma always says... Mizusaki Yuuma: Stop nagging Grandma, when are you going to pay back what you owe? In the corner, Mai Shiranui, remembering she still owed money, was trembling. ...

A familiar, thin figure was standing at the doorway.

He wore a yellow and black square haori, and his long, deep red hair was unusually tied in a high ponytail.

He was holding a katana that he had never seen before.

That was the back view of his father, Tanjuro Kamado.

And facing Tanjuro face to face.

It was a man Tanjiro had never seen before, dressed in a black suit and wearing a small top hat.

Because Tanjiro fell in the snow, he couldn't see the expression on his father's face, who was turned away from him.

But he was able to see the other side.

—The man in the black suit, his red eyes revealing a look of horror.

That was an expression as if he had seen a ghost.

Yao Jia probably never expected that hitting the jackpot would actually damage his soul.

Countless fragments of souls, carrying Yao Jia's essence, crossed dimensions and were reborn as familiar or unfamiliar two-dimensional beings.

After retrieving the reincarnated soul fragments, Yao Jia, as the main body, could directly resonate and gain power, but unexpectedly, all the clones were of the opposite sex...

Huo Yuxi: "Can a mere God Realm withstand a punch from me, a being of stellar level?"

Liu Ou, "Comprehend the laws of space? Would you like to see my spatial authority?"

Kiana: "All tragedies crumble before 'me'!"

Yao Jia some time later—

"Was I really this narcissistic?"

My wife is so beautiful! (×)

I'm so beautiful! (√)

Eric, who had been forced to play The Sims for ten years, opened his eyes again to find himself finally in control of his body. Before he could even get started, he was bombarded with a barrage of information that left him dizzy. "I've arrived in the magical world of Harry Potter? And the original system has self-destructed?" When the Sorting Hat was placed on his head and loudly proclaimed Azkaban, Eric knew he was destined for greatness.

Does anyone in the family understand this?

I was just walking down the street and did nothing, but I was forcibly transported to another world.

I've traversed ninety-nine worlds at the same time, and even encountered a useless system that's completely ineffective. It's really frustrating.

Fortunately, I'm quite capable.

They can share their abilities with each other.

Having traversed so many worlds, what does it matter if they're all just accessories?

Even a pair of underwear or a piece of toilet paper has its uses!

You can get rich by collecting garbage!

Besides, if you walk in the dark too often, you're bound to step in poop!

Since the system is useless, my cheat is myself!

Big shots like Xia Yan: So this is why you're not ambitious and just waiting to suck up to powerful figures? ×N

Xia Yan (Keychain): That's right, everyone is their own father. Dad, love me again!

Hentai Natsuhiko: You unfilial sons, it's time to show you who the real father is!
