Reincarnated with an Analysis system. - Chapter 24 Orland Free?

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.

Derek Carter never asked for a System, an apocalypse, or the pressure of being humanity’s so-called “last hope.”He was just trying to survive the daily struggles of being an orphan in Paleview City—dodging bullies, scraping together meals, and lying his way into school. Life was already hard enough.Then, one day, a blue screen pops into his vision:[Warning: The world is doomed. Try not to die.]Yeah, great. Just what he needed—cryptic doomsday messages and no instruction manual.Now, monsters are creeping into the city, reality is unraveling, and Damien’s “legendary” starting stats are barely above zero. The System promises him power, but there's just one tiny problem—he’s never won a fight in his life.Armed with sarcasm, questionable decision-making skills, and the sheer refusal to die, Damien is about to embark on the worst (and possibly last) adventure of his life. Because if the world really is ending… he’s at least going to make it someone else’s problem first.After all, heroes are overrated—survivors get to tell the story.
