Hell's Handbook - Chapter

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.

Hye lived his entire life without a class. After the apocalypse hit the human world, strange creatures invaded and killed humans while new lands were being added.

Systems were given to humans and with the help of the guides, humans started to fight back for their lives. All of this happened under the watch of the venerable beings who were shining stars in the sky; gods!

Hye dreamt his entire life of a chance to prove himself. He was a hard working, earnestly learning and smart youth. However, the apocalypse never was merciful to such humans at all.

Until one day he got a chance to go back in time, when everything started. At this new starting point, he found himself able to finally obtain what he wanted, a class for himself and power beyond imagination.

But will things be this easy for him?

Her childhood was forged in shadows, and she was sharpened into a weapon, trained to be a ghost, a killer—an instrument of vengeance. The target: a decorated general who brought down her family.But fate doesn't follow orders.Just as Lara was about to execute her long-planned mission, everything spiraled out of control. A military convoy intercepted her escape route—escorting none other than the general himself. And then came the moment that changed everything.A blinding crash. Screeching tires. Her body was thrown like a ragdoll, then darkness.She had a fleeting recollection of another world, another lifetime where kings ruled the land with an iron fist.But she woke up, and twelve long months had passed. She did not know where she was or who she was. She remembered nothing.They told her different names.A child with trembling hope whispered, “Mommy, your name is Moira Torres.”Her doctor insisted, “Your admission slip says Larissa Reyes.”A hardened general leaned close and commanded, “Remember who you are. Remember your mission.”Then another general—dangerously calm, incredibly familiar—looked at her as if she mattered and asked, “Can I call you Lara?”The name unlocked something buried deep in her soul.Lara Norse Kromwel.Daughter of General Odin Norse.Empress of the First Empire.But the man who watched her most closely dismissed it with cold certainty.“This is the 21st century,” he said. “What nonsense are you spouting? What Empress? You are my woman. You can only be mine!”

To pass as an imperial concubine, one must be professional.

Actually, the profession of an imperial concubine is pretty good. The emperor will accompany you in eating and drinking, and even pay you for it. What’s not good about that?
