SSR-ranked killer Mu Hui died in an explosion, only waking up to find herself transmigrated into the body of a vicious female supporting character in a book. The original Host was as stupid as a pig. As the lover of the villain, she helped the male protagonist steal the important documents from the villain and backstabbed the villain for the male protagonist. The ending was, of course, being attacked by both the male protagonist and the villain, and, dying miserably. And the point where Mu Hui transmigrated was the moment when she stabbed the villain and ran to the male protagonist's side— What could she do to change her fate? Mu Hui made a prompt decision and placed the knife that had stabbed the villain onto the male protagonist's neck. "The scene just now was deliberately acted out by my man and me. Return the document to my man immediately!" The male protagonist: ""???"" The antagonist: ""???"" Later on, Mu Hui constantly helped the villain Fu Siye fight monsters and level up, just so that she could live longer and return to her original world. However, one day, after a bath, the villain came up to her. "You've been my lover for so long. When are you going to consummate your marriage?" Mu Hui: “???” This was not how it was written in the book! [Even if it is meant to be, it can be changed step by step.]

This is a Naruto/Naruto Shippuden/Boruto fanfic. It is possible that the MC might venture into other worlds but that depends on how everything goes. By the way, this novel will feature a system but before you start rioting, this system will not feature any bloodlines or summonings or anything like that. It's gonna be from one particular series, and the series in itself is going to be weaker than naruto so don't expect an OP mc from the start. There's gonna be a lot of training too.

A guy gets hit by a truck and sent to a fantasy world with less power than your average peasant. (Un)fortunately, he discovered his secret power of Immortality at the hands of the current destroy-the-world inclined Demon Lord and becomes experimental subject #1. After hundreds of years, the Demon Lord is killed and the job of destruction was handed to him. Being not terribly favorably inclined to this fantasy world, he wreaks havoc on the world... Killing sacred beasts, massacring cities with an army of undead, headhunting servants of God, plaguing a whole continent with a deadly virus. But he was still unsatisfied. During an experiment, he accidentally killed himself trying to open a gateway to a new world. And wakes up from his coma in his original world. Except, it isn't his world, exactly. Now there is a man in a metal suit, a 90-years old buff dude with a shield, a muscle head demi-god and other weirdos who formed a team called the ‘Avengers’. None of that matters though, because he is so over all that drama. This life is going to be carefree. Or at least, that's the plan. P.S. The cover picture is not mine, it is only borrowed. If the owner (redflowers) claims it, I will obediently replace it.

Life is unexpected after all. Unexpected and mysterious. You never know what could happen. Even so people have certain expectations. Things in the line of reality. Things that could actually happen. Simple things. Like being a doctor when you grow up. Or winning the lottery. Becoming the president. These are all things that are within the line of reality.

The impossibilities keep on going. Not only did she wake up in a forest, find out she was five and suffered from short term memory loss,she somehow stumbled upon the gate to the leaf village. The line of reality had completely shattered
