Zhou You is an ordinary high school underachiever.

With the college entrance examination approaching, Zhou You, who couldn't write a single word, sat anxiously in the examination room, scratching his head and about to hand in a blank paper when a cold, mechanical voice appeared in his ear.

[Ding! Congratulations on successfully installing the God of Scientific Research System!]

[Newcomer Gift Pack successfully received! Congratulations! You have obtained the Controlled Nuclear Fusion Research and Development Program!]

In order not to fail the exam, Zhou You decided to try anything, even if it seemed hopeless, and started doing research on the exam paper on the spot... That day, the top leadership of the Dragon Kingdom was in an uproar!

A few days later, a military helicopter quietly landed in a residential area, and Zhou You was never seen again.

Soon after, controlled nuclear fusion, warp drive, individual mechs, gene editors... one after another, groundbreaking technologies were born in the Dragon Kingdom, completely rewriting the history of Earth!

On that day, people called him the god of scientific research.

[Conan Fanfiction]

I traveled through time and space and became Kudo Shinichi's younger brother? Are you kidding me!

I don't want to be a detective, I want to be a cartoonist!

Sorry, Shinichi...it's not that I don't want to help you, I just really want to have a younger brother named Edogawa Conan.

By the way, what do you think of my cartoon's protagonist being a Shiba Inu wearing a blue suit, gray shorts, and a red bow tie around his neck?

Isn't it very creative?

Eight hundred meters away, a sniper rifle locked onto his head, yet Bai Chuan remained calm. Fifty meters away, bombs surrounded him, yet his expression remained unchanged. Two meters away, a sharp blade pierced his throat, and Bai Chuan put his hands in his pockets. "Seriously? Is that all you've got?"... Reporter: "Mr. Bai Chuan, what sustains you in always being on the front lines of danger? Is it courage, faith?" Bai Chuan shook his head: "It's fun." Reporter: "Mr. Fun Man, what allows you to survive unscathed every time? Is it knowledge, experience?" Bai Chuan paused for a moment, then honestly answered: "Because I'm immortal." Reporter: "..." Reporter: "Then, Mr. Immortal, there are rumors that you seem to want to live a peaceful life." Bai Chuan nodded excitedly: "Let me clarify, this is not a rumor!" This book is also known as *The Mischief-Making Journey of an Unregistered Resident in the Underworld*...

A third-rate painter in the past life, and a chaebol in this life.

I thought it was a rebirth flow, but it turned out to be a system flow. I wanted to rely on myself, but you let me use a plug-in.

[Detective Conan fanfiction, no romantic pairings, original pairings not broken] With an innate keen sense of smell, Takashima Munenori embarks on the path to becoming a police officer to uncover the truth behind his parents' deaths. Little did he know that after helping the police solve his first case, he would earn the nickname "human police dog." [Will involve real cases, Kindaichi cases, and cases from Japanese dramas, etc.]

Lin Feng traveled to the world of science.

He found that his physical fitness could be improved unlimitedly.

He had to practice Bajiquan well and show everyone what it means to tear up a winery with bare hands!

"The crime rate in Beika Town is getting higher and higher."

After two and a half years of debut,

Lin Feng, who won the Beika Town Most Popular Repairman Award for two consecutive years, said so.

Conan: "Would you like to put down the bloody bat in your hand before talking?"

Gin: "When I find you, I will tear you into pieces!

" Vodka: "Brother is so handsome!

" Binga: "How much does it cost to kill the two upstairs? You name your price!

" Amuro Toru: "What a headache."

Akai Shuichi: "I still don't believe you can dodge the bullets of a sniper rifle."

Kid: "Put away your curiosity and stop staring at my skirt."

Kyogoku Makoto: "Are you a Super Saiyan too?"

Ai: "1.2.3.4.5... The people upstairs are all idiots."

As we all know, the crime rate in the world of Conan is one of the highest.

As a lawyer, Gumeimen Research Association received various cases and defended various suspects, which of course included many murderers caught by a little boy in blue with a bow tie.

"Lawyer, I have a dog..."

"The dog you raised is a stray dog."

"Lawyer, I was hit in the head by a ball kicked by a little boy in blue with a bow tie. Now I have been diagnosed with a second-degree concussion. Can I have my sentence reduced because of this?"

"Leave aside whether the sentence will be reduced or not, are you interested in entrusting me to sue the child's guardian? Let him pay a large sum of money!"

"Lawyer, I found that my home was bugged..."

"Stop talking, sue him severely! Let him lose everything!"

Not long after, Kogoro Mouri, holding a pile of court summonses, kicked Conan out of the door.

Also known as "Conan: Li Gou Hai", "Conan: Legal High", "Conan: Losing Conan to Enter the Screw".

After I transmigrated into the world of Detective Conan, the system turned me into a cat and then exploded.

From then on, the world of science fiction gained an incredible blue and white British Shorthair.

Conan: That dead cat is a master at taking candid photos. I don't know how many embarrassing moments of my life have been photographed by him.

Ran Mouri: Tom is amazing. I can understand what he means from his shouts.

Vodka: That dead cat was ridiculous. I clearly saw the bullet I fired riddle it with holes, and even when it crawled out of the pond, its body was leaking water like a showerhead, but in the blink of an eye, it was perfectly fine again.

Gin: When I pointed my little pistol at that dead cat, that dead cat pulled out a Gatling gun.

Kidd: I thought I was good enough at hang gliding, but that dead cat can turn a piece of wood into a cat-shaped hang glider.

...

This is the story of a cat with Tom Cat bloodlines wreaking havoc in the world of Detective Conan.

Years later, when Conan saw Ran nestled happily against Yuya, he felt a deep bitterness in his heart.

Conan never expected that while he treated Yuya as his childhood sweetheart, Yuya secretly stole his old friend.

But Conan had to admit:

"Perhaps only a kind-hearted angel like Yuya is worthy of Ran!"

In response, Ai Haibara said it's all Kudo's fault!!

He lost his childhood sweetheart because of the case, forcing her to face a formidable opponent like Ran Mouri!

From the day she met Yuya, her cold heart gradually warmed up: she realized that there was still a gentle and pure warmth in this world, just like her sister's, something she was willing to let down her guard and do everything in her power to protect.

However, looking at Ran and Yuya nestled together, Ai sighed softly:

"I'm sorry, perhaps I've come at the wrong time..."

“No, Ai, you’ve come at just the right time.” Yuya extended his left hand in an invitation, and then embraced Ai.

All of this begins with Yuya, who is trapped in the world of Detective Conan but suffers from a terminal illness, risking his life to steal Drug A from the alcohol factory.

The terminal illness was not cured;

Instead, the "favorability system" was awakened?

Daily interactions and occasional simple tasks can increase favorability, thereby obtaining treasure chests that can contain various items, including those that increase lifespan.

But these tasks...

Yuya muttered to herself, then offered everyone a cup of fragrant green tea.
