The Dark Rebirth of Pandora: Revenge of the Abyss - Chapter 290: Surprise invasion

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.

A noisy little family, a cheerful group of classmates, and a boy, born on the first year of the lunar calendar living a never changing life. Then one day he notices a girl in his class shrouded in mystery. Her name is Makina. However, the boy just can’t seem to bring himself to talk to Makina. Then one day, before the first lunar calendar month, another mysterious beauty appears. Her name is Rushia, and as she leans in as if she is going to kiss him, she tells him about a mysterious power hidden inside him called the “Snake Eyes.”

A 40-year-old man suddenly dies and is reincarnated in a world devastated by zombies—but instead of becoming a hero or a survivor, he wakes up as a zombie girl.

Amid the silence of the aftermath, a sealed envelope was found resting beside the fallen Infinity Blade. Its edges were worn, as though it had been carried for many years, yet the seal remained intact. Gok, known for his stoicism and strength, had written it long before the final battle, anticipating that one day his journey would reach its end.
