Naruto: Konoha's Psychic - Chapter 222: Ch- The Transformation of Kirigakure.

What happens when a scientist from a futuristic world reincarnates in a World of Magic and Knights? An awesome MC is what happens! A scientist’s goal is to explore the secrets of the universe, and this is exactly what Leylin sets out to do when he is reincarnated. Dark, cold and calculating, he makes use of all his resources as he sets off on his adventures to meet his goal. Face? Who needs that… Hmmm… that guy seems too powerful for me to take on now… I better keep a low profile for now. You want me to help you? Sure… but what benefit can I get out of it? Nothing? Bye. Hmmm… that guy looks like he might cause me problems in the future. Should I let him off for now and let him grow into someone that can threaten me….. Nahhh. *kill*-

Alternative: Leylin is transported from an advanced technological era into a medieval world— except there’s magic. Equipped with “only” his quick wits and an A.I. chip fused to his soul, he sets out to become the most powerful magus the world has ever known. In a land divided into the Light and Dark Magi, the weak can either be cattle or disposable slaves. Only the strong can determine their lives, and only they have the luxury for virtue. Yet strength is only a tool for Leylin, like any other. His goal, in the end, is his own.

He is the emperor of the business world. Rumor has it that he was fond of men and because of this, Song Wen Xin agreed to marry him.

After their marriage, he proved to her that he has the ability of a normal man!

“You are not allowed to hide when fulfilling the obligation of husband and wife. You are also not allowed to refuse the gifts that I send you. And, when you take the initiative to come to me… you are not allowed to stop!” He ordered her overbearingly.

Song Wen Xin immediately said: “In your dreams!”

He laughed enigmatically: “What a coincidence! I’m best at making a dream into a reality!”

He dotes on her, dotes on her with no bottom line at all…

Look, I’m Riven Kael.Twenty-eight, data analyst, zero ambition beyond paying rent and avoiding small talk. My life was spreadsheets, instant ramen, and the occasional ghost I pretended not to see.Then one mandatory company gala, because of course it was mandatory, turned into the universe’s worst prank.I touched a cursed amulet.I just touched it.Next thing I know, I’m waking up in a penthouse that costs more than my entire bloodline, sporting a glowing marriage sigil on my wrist, legally and magically hitched to Azryth Valek.Yes, that Azryth Valek.The CEO of half the planet, a walking sin in a three-piece suit, an ancient demon lord who was literally sealed inside said amulet until I accidentally set him free.He says we’re bound. Separation means both of us die slowly and painfully.Soul-consumption optional but very much on the table if I’m stupid enough to fall for him. Which, newsflash, I am not. I’m not.Shut up.So now I’m living with an unfortunately hot CEO from hell, dodging assassination attempts disguised as corporate mergers, banishing spirits that show up at my desk like unpaid interns, and pretending we’re a power couple for the cameras while he smirks like he knows exactly how much I want to strangle him. Or kiss him. Or both.Brain, we are not doing this.I didn’t sign up for boardroom battles, multiversal rifts, or the terrifying realization that the arrogant demon who ruined my life might be the only one who truly sees me.But here I am. Still complaining, still fighting, still falling, against every shred of common sense, hopelessly, stupidly, irrevocably in love.Because when the universe marries you to the devil, it doesn’t ask for consent.It just hands you the ring.And damn it, I’m keeping it.

The world is made up of the five elements, and it could be divided into Yin and Yang.

Beneath the heavens, on the ancient divine center continent, billions of lives thrive in the prosperous era of the cultivation.

Across its vast lands, happiness, sadness, reunion, and separation played out in the long lives of those seeking immortalhood.

Light is always accompanied by darkness, and under the radiance of the heavens, there are silent shadows moving about…
