Sins Paradise: Domination System - Chapter 14: New Quest

Fat kitty died, killed by a lightning strike while stealing a chicken leg! And then, the kitty was reborn into a rich family in the 80s, which, having had nine grandsons, longed for a granddaughter and instantly made her the most adored one in the family! She was so happy with her life, being pampered by grandma, adored by parents, and protected by big brothers. Of course, it would have been even better if that big bad wolf hadn't cast covetous eyes on her.

Daniel is just a regular blue collar Maintenance Mechanic working for a manufacturing company. As he's winding down at home from a day of messy work repairing a CNC mill, he is surprised by a sudden glow of light beneath him. And, in an instant, his world changes. Literally.Daniel finds himself now in the world of Zenkon, a world of fantasy beings and monsters, swords and magic, and perilous threats to the safety of the world. As if stepping into a fantasy light novel or video game, he has been apparently summoned by a sacred magic spell that requests a hero from the gods, and in reply, they sent Daniel and a young Japanese man named Rikuto.However, Daniel's luck doesn't seem to be good, as it's quickly discovered that, contrary to the nature of living things in the world of Zenkon, Daniel is the only one that possesses no magic or mana, making him immune to many types of magic, both beneficial and detrimental, but not protecting him from direct harm.As such, Daniel will now have to find his way through this world using his own repair and manufacturing know-how, while Rikuto uses his own modern civics and economics knowledge to try to recover the Kingdom of Mornistae in the midst of a large scale global war.Why were they summoned, and by what wisdom did the gods choose to send 'Divine Heroes'; one with magic and the other without, to a world of which the foundation is magic?

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.
