I Lost the Leash of the Yandere Male Lead - Chapter 4

An Individual from Earth finds themselves in the Shinobi World, equipped with a Scientific System. From that moment, he delved into scientific research far ahead of its time.

Hey Guys, this story is written by Sinyk on fanfic net. This is not my work. The only reason I am putting this up is because someone has copied Sinyk's entire work word-for-word on this site (claiming it as his own: Harry Potter and the 7 angers), releasing it at a snail's pace, and is also making money off of it on patreon. Pisses me off to no end.Art is by CruderFive1 on DeviantArt-----------------------------------------------------------------------------------------------Disclaimer: The Harry Potter universe belongs to JK Rowling, Scholastic, Bloomsbury, Warner Bros and some other high falutin' companies. Me, I'm just a PR professional. I don't profess to own - and would never dream of making any money off - JKR's wonderful world. However, its her sandbox and she's left the gate unlatched so we can go in and play a bit. Which, I've done.-----------------------------------------------------------------------------------------------Okay, guys and... guyettes,This one is of epic length. And by that I mean really really long. For those who sent me a note about 'Four Heirs' and thought it long - well, this one blows that one out of the water for length. So, if something only up to - say - 150k words is your cup o' tea, then this isn't for you. No sir-ree! This story hits approximately 480k words.To stop all the whining and bitching right now - yeah, like that's ever going to happen - you'll figure out this is a 'Haphne' story; Dumbledore is (somewhat) good but still manipulative as per canon; Ron's an ineffective non-entity; Snape tries to keep sticking his beak in - and get's it repeatedly thwacked with a rolled-up newspaper; McGonagall gets over her hero-worship of DumDum (I mean, Dumbledore); Hermione is a good friend; Sirius is free; kids are kids; and teenagers are walking bags of hormones.The story follows canon a lot; and I've even included many quoted sections out of the books. I didn't do this to pinch JKR's works. Rather, it's in there to demonstrate similarities while being a different story. So, no biatching about that, either. You've been well and truly warned.Yours,Da crazy bastard who thinks he's an author.

This is the 40,000th year that the Empire has ruled the Milky Way. The glory of the Great Crusade has long been lost in the dust of history. Su Yu traveled through time and opened his eyes to see the ruined planet in front of him, with a confused look on his face.

On this planet, there are extremely dilapidated war machines that stretch for thousands of kilometers, alien behemoths whose roars can shatter mountains and rivers, and radiation that can cause further damage to the surrounding environment just by moving. Alien beast——

There is everything here except hope.

Regardless of whether he wanted to or not, Su Yu, who had struggled to survive for three years and was inevitably infected with radiation sickness in the end, seemed to be one of the desperate people.

Until his career panel, which allows for unlimited career changes, was finally opened.

“Ding!”

“It is detected that the host has met the prerequisites. Do you want to take up the occupation [Mechanic]?”

“After completing this profession, you can gain professional experience and improve your professional level from daily maintenance, recycling, and assembly of mechanical creations. With each upgrade, you can gain an increase in physical fitness…”

Looking at the old gun parts piled up in his repair room, Su Yu’s eyes lit up like never before!

Many years later, at the core of the empire, at the highest point of the Terran world, the mechanic from the Ruined Star, the Ghost Shadow Blade of the Dead Wasteland, the restarter of the Titan Weapon Plan, the Governor of the Broken Star Territory, the Lord of Mechanical Ascension, the Supreme Throne of the Forge World, Su Yu looked at the torrent of steel coming from below and waved his hand to give the order!

[Our goal is to make the (second) (crossed out) empire great again! 】

I am the sword.
Killing a man amidst a thousand miles, no one dares take ten steps.
Killing a man amidst a thousand miles, no one can take ten steps.
Killing a man amidst a thousand miles, ten steps? Not possible!
I am the sword, the sword is me,
On the path towards heaven, each shall wield their own.
