[Time travel + comedy + no system + multiple female leads + indirect approach to achieving one's goals]

(This story has a lot of funny and romantic slice-of-life moments in the early stages, and it's not just a pure wish-fulfillment story with constant showing off. You can read it if you think it's worth it.)

In the year 1485 of the Solar Calendar, a shocking scandal broke out in the Famia Empire—

That human genius scholar who improved the calculation formula, invented soul-sensing magic, and ended the elves' more than 100-year reign in the "Strongest Magic Brain" competition.

He doesn't know any magic at all; he's a complete low-magic user!

——

Reincarnated into another world, Owen became a useless young nobleman.

Despite lacking magical talent, he unexpectedly discovered that magical theory was quite easy to learn, even less difficult than calculus in his previous life.

"Perhaps I can change my fate through the exam?"

Thus, Owen rekindled his test-taking spirit and gradually emerged on the academic stage as an unconventional genius.

"Orc, so what if you're strong? Can you solve problems as fast as I can?"

"Elf, so what if you have a lot of magic? You'll still beat me on the exam first, won't you?"

"So-called genius is nothing more than one percent inspiration and ninety-nine percent perspiration."

At the graduation ceremony of Vilia College, outstanding graduate representative Owen delivered a passionate speech on stage:

"Even if I'm just a country bumpkin, I'm determined to go and snag a cabbage in the capital."

“Fira, Tomman, and Rice, who created the magic formula when he was 9 years old because he wanted to get out of school quickly—heroes are as numerous as fish in a river.”

"Please remember the name Owen."

"Because one day, I will, like my predecessors, make it resound throughout the world!"

Bound to an improperly trained "simp" system, charm increased tenfold! First, a small goal: dominate all the beautiful girls in school...including teachers and the principal! Huh? They're all so proactive! Kasumigaoka Utaha: Can we have a dating simulation? (For research for my new book.) Li Kong: Lots of people ask me out, remember to book in advance next time! Himuro Ayame: Are you free for dinner tonight? Li Kong: Yes, but I never pay for dates with beautiful girls. Himuro Ayame: Then I'll treat you. Ellie: The girl you were having dinner with last night, the one you were being intimate with, looks a bit like my sister? Li Kong: She's your sister. If you have a problem with that, let's break up! Ellie: It's okay, I can't live without you. Ayase Saki: Was that a girl you were talking to on the phone just now? Li Kong: She's your mother. She asked me to go to a hotel tonight. ...Hayasaka Ai: A maid who doesn't want to be the mistress isn't a good maid! Kitagawa Kaimu: If I win this battle, you have to go out with me! Kirisu Mafuyu: I haven't handed in my homework yet! Toyokawa Shoko: You've taken all my teammates... Saionji Sekai: Mom's shoes are here too, and this voice is... (Male/Female, all virgins accepted)

[Starting with Chronos + Kamen Rider + Crossover Anime + Tanzaburo Higashijima + Nisekoi + Multiple Heroines]

Transmigrating to various anime worlds, Shi Wushuang begins as Kamen Rider Chronos. In the realm of the God of Time, day and night are but a thought away, and time stops and flows backwards only for him.

On campus, Shi Wushuang is a gentle, cheerful, and sunny male god, but when facing strange people, he is a cold-blooded judge and a grim reaper.

The city's impurities, the Amazon lurking in the shadows, the constellation apostles on campus, the Shocker monster causing chaos, and monsters from other knight worldviews in the dimensional rift, and the BOSS.

When he is Kamen Rider Chronos, he puts his index finger to his lips and says, "Shh, during the trial, the scene must remain serious."

When he was Kamen Rider Eternal, he gave a thumbs-down sign and said, "When you get to hell, just say my name, Shinigami, and you can skip the toll."

When he is in Kamen Rider Evol Black Hole form, his right hand spins like a black hole: "This day next year will be your death anniversary, Ciao."

When he was the Blade of the God of War, he pressed his thumb down on his index finger and said, "Don't misunderstand, I just want to kill you all, or be killed by you all."

When he is Oma Zi-O: "If you do not bow to the king, you have already lost your true destiny. Your name is on the Reincarnation Stele. Bow with each step. If you are devout and sincere, your sins will be halved on the road to rebirth."

All sorts of weirdos: What? I'm taking on the Knight Boss one-on-one?

...

The tentative list of female leads includes: Elisa who speaks Russian from time to time, Shiina Mahiru, the angelic neighbor, Okada Yuriko, the eccentric Takumi, Kirisaki Chitoge, Kato Megumi, and Kasumigaoka Utaha, the black-stocking fanatic.

After the college entrance exam, Jiang Xiao was bound to a super-rich system called "Money to Spend." However, upon learning that activating the system required saving 1 billion yuan, Jiang Xiao was extremely frustrated. At the same time, his parents disappeared.
