How to Live Another Five Hundred Years, Conan-Style

After Gao Song Linkong died unexpectedly, he not only transmigrated into the world of Detective Conan, but also signed a contract with the System.

The good news: the System promised he could come back to life if he became the most popular person.

The bad news: the story was still thirty years from beginning.

Gao Song Linkong: ...Damn.

By the time the story began, he'd be an old man! Professor Agasa was three years younger than him!

Knowing the mission was hopeless, Gao Song Linkong decided to give up and make the most of... use those extra thirty years. Compared to dropping dead on the spot, he was getting a good deal either way.

To live the carefree life of someone with nothing to worry about, Gao Song Linkong took a job at the organization's training camp, looking after a bunch of brats, and planned to coast until he died.

As soon as he walked through the gate, he saw an instructor grabbing a golden-haired, dark-skinned boy by the head and smashing him into a wall.

Hold on. Who are you?!

Gao Song Linkong accidentally discovered a shocking secret.

The organization had abducted a group of children to train them. Among the victims were the future cat-eyed FBI agent, a curly-haired demolition expert, the one and only genuine criminal...

The bad news: the young members of both the Red and Black sides had all gathered right under his nose.

The worse news: he had to make sure they grew up healthy and made it to adulthood.

Gao Song Linkong, forced to do sit-ups: ...Heh.

The weather's getting cold. Time to start taking revenge on society.

When they were abducted, Rei Furuya and the others were filled with despair.

They would rather die than join forces with evil.

Especially that man.

He taught them, protected them, and showed them the greatest kindness possible in this world that devoured people.

But he also cursed at them, looked down on them, and forced them to carry out missions.

Until they discovered that the so-called philanthropists in their missions trafficked people and organs, and treated human lives as worthless.

The so-called high-ranking officials could cover up anything, drawing their salaries while doing nothing and using their power to make money.

Only then did they realize:

From beginning to end, he had only been guiding them: Treat other people's suspicious looks like flickering ghost fires, and boldly walk your own path.*

Gao Song Linkong, who finally realized he'd landed in an inverted world timeline and was furiously going through missions: What is going on in this world? There are so many missions, and I can't take down a single good person!

Note:

*From Shi Tiesheng

1. No CP, everyone gets saved.

2. The world is extremely dark. This is all for the plot, so please don't compare it to reality.

3. Some canon characters switch to the Red side (or maybe they're more gray than red?).

Theme: Hold on to your principles, even in the dark
