MTL - The Inverted Dragon’s Scale - Chapter 882 , China Totem!

When an S-class elite assassin-raised captain of a special ops suicide squad comes home from a high-stakes Africa mission, he finds himself offered something that could potentially set him up for life- a curious assignment that he could use to finally exit his days of war and slaughter.

Then placed into a high-school setting, Lin Yi is tasked by the chairman of a top-tier multi-billion company with bodyguard duty for non-other than his own daughter, a certain little Miss of said high-school.

His enemies, once ranging from drug lords, mafia bosses, political figures, and national leaders, are soon replaced with spoiled kids who happen to have rich papas and mamas, and Lin Yi finds his intense expertise and high-threat skillset misused, and very underwhelmed…

But he does get a harem cast as diverse as his old enemies, so Lin Yi decides that, for the sake of messing around with girls as an invincible entity in a down-leveled environment, leaving his bloody and death-filled war days behind is something he’d definitely want to strive for.

- Description from Novelupdates

Kay didn't have the best life. Most of it was fairly standard, but his past was marred by a tragedy that changed his entire world. Years later he had managed to mostly rebuild his life, and had started making something of himself.

And then he woke up in a different world. A world of fantasy and [Classes], a world much more dangerous than the one he'd been born in.

The new world he's been dumped into doesn't hold anyone's hand. Even with the bonuses that being an Outworlder brings won't keep him perfectly safe. One mistake could kill him in an instant.

But maybe, with a little bit of help, he could start over once more, and start to make something of himself again. And maybe, just maybe, that something he makes himself into could be amazing. And bloody.

As I'm leaning right now there probably will be sexual content later on, but I might change my mind later. There definitely will be death, gore, violence, and blood. Lots and lots of blood.

I changed my mind. No adult stuff in this story.

He transmigrated and got a system but Lin Feng’s pressure is as big as a mountain.
