I Don't Agree to the Terms - Chapter 360 - 206: Whosoever Desires the Opportunity Indicating Great Misfortune Can Have It

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

Living an unfulfilled life, Zack Gray meets an untimely end–that is, until he’s given a second chance, in a new world, under a new name: “Leon Schoeller.” Heir to the Schoeller Estate, a powerful and prestigious noble family, a life of luxury surrounded by maids and butlers of elite skills of their own awaits the reborn man.[Lord System Activated.]In addition to being blessed with a genius mind and magical talent, the [Lord System] grants Leon supernatural abilities, from empowering his servants, conquering beasts, and even manipulating his mansion.However, as gifted as he finds himself, the world around him is full of lurking threats, forcing him to level up if he expects to keep his cozy life intact.

[A Naruto “OC-SI” Fan Fiction]Make the best of what you have, they said... But what I am supposed to do when the best I have are red-eyed freaks, a child who's supposed to be the jailor of the most dangerous being in the world, a snake creep with serious boundary issues, and a whole world of super soldiers with licences to murder.And you know the best part? None of them like me so much...Oh shut it, old man! Take that Will of Fire and shove it up your—Yeah, this second swing at life isn't panning out...---------------------------------------------------------------What to expect:- Gradual strength progression. Meaningful growth. The MC is a normal guy dumped into the Narutoverse, starts out weak and has to work and struggle for everything he gains.- “Slow” paced. My writing style is a zoomed-in look camera that follows the protagonist. It might seem slow, but I ensure something is always happening to progress the plot forward.- Gritty and often bloody fights and actions scenes with a focus on taijutsu—you'll see individual combat, team fights, and large-scale battle.- A different take on the Narutoverse. The world is full of superhuman mercenaries with liscenes-to-kill—that along with the protagonist's struggles paint the world in a much darker light.- Additions and expansion to the “chakra” power system. I consider myself a conservative when it comes to adapting the power system—and aim to retain the original feel while highlighting the best parts.- The Outsider's Resolve version of Narutoverse uses the [Naruto Manga] as the base—with additions from anime, books, and even Boruto (though very less likely).

Tired of the schemes and strifes of city life, Bei Feng finally returned to his hometown in the countryside

While picking asters ‘neath the Eastern fence;

My gaze upon the Southern mountain rests;

Rearing a few chickens and ducks, I shall lead a simple and leisurely life!

However, who would have thought that fate would play a huge joke on Bei Feng? All kinds of magical items and beings of the Myriad Worlds could actually be fished out of the Ancient Well in his yard!

Even a chicken reeled out of the well ended up chasing Bei Feng all over the yard and beating him black and blue! Speechless and aggrieved, he asked the Heavens: if, that day, he’d fished out a Dragon instead of a chicken, what would’ve happened to him!
