A traveler from another world is mysteriously summoned into the world of Demon Slayer. Armed with no overwhelming strength, nor system at his disposal, he sets out on a journey to heal the sick, save lives, and uncover the secrets hidden within the world's deadly diseases and mysterious plants.
As his travels take him across the land, he eventually discovers the legendary Blue Spider Lily-a flower long sought after by a certain demon king. Using his modern medical knowledge and the traditional medicine he learned during his travels, he succeeds where others failed, creating a perfected medicine unlike anything the world has ever seen.
With his greatest breakthrough complete, he embarks on an entirely new path: the road of cultivation. Combining science, medicine, and spiritual growth, he begins a journey that will reshape both himself and the world around him.

Anime: Starting in Jujutsu Kaisen with Vector Control!
For sixteen years, Konoe Mayoru thought he was just living a perfectly normal life in an everyday anime world. Then, the sky collapsed. He woke up to find himself chosen as a Culling Game player, forced into a brutal battle royale against resurrected ancient sorcerers. How could a regular modern person possibly stand a chance against those monsters? Desperate, Mayoru checks his newly awakened Cursed Technique, only to discover it is Vector Manipulation-the absolute ability to manipulate the direction of all energy and matter. Though his brain lacks the computational ability at first, Mayoru finds a workaround: by consistently landing Black Flashes, he can streamline his algorithms and forcefully refine his cursed energy precision. As long as he can understand the energy or matter, he can dominate it! When the King of Curses confidently boasts that Mahoraga has adapted to his technique, Mayoru merely smiles: "He only adapted to who I was a moment ago. I've already recalculated a new formula to counter his adaptation. Curses, sorcerers, even the concepts themselves-everything bends to my calculations. King of Curses, you are nothing but an ordinary man born in an era that lacked my presence!" --- Please Note: I do not own anything in this fanfiction.

A PATCH IN THE CODE
"Where am I?..." a soft, monotone voice whispered, its owner looking around. His creation was alive; the experiment worked! "Ho-o-oly sh-sh-shit-t," the skeleton muttered in awe, starting to glitch more. "I-i-itt wor-orked, ho-holy sh-shit!" "What worked..." the doll asked, looking up at the skeleton in front of it. He let out a stuttering, almost manic laugh, the doll simply waiting for him to calm down. "I-I-I cre-e-ated-ed y-y-you," he finally told it, grinning. "Yo-ou-ou're-u're my-y cre-eation-tion." WARNINGS This fic will contain minor swearing, complicated relationships, skeletons, minor questioning of existence, and quite a few shenanigans from previously mentioned skeletons.Complete

Forward | Rewind to Tomorrow [Michael Jackson]
"It causes your immune system to turn against you," I explained gently. The color terrifyingly drained from his face as he stared at his knuckles. "I have a spot," he whispered, his voice scraping like glass. "Right here." He let out a strangled noise as the stadium footage buffered. "Riley!" he shrieked, covering his burning face while peering through his fingers at his future self. "Those pants leave absolutely nothing to the imagination!" He went so unnaturally still I thought his heart had stopped beating. His charcoal-stained fingers curled into tight fists. "Fifty," he whispered, scanning the fatal summary on the glowing screen. "I am... I am gone at fifty." What if the only way to save your future was to completely abandon your past? In 1982, Michael Jackson is suffocating. Trapped behind his family's compound gates and drowning under industry pressure, the rising star just wants a life of peace and normalcy. The universe answers-violently ripping him from his timeline and dropping him onto the bedroom rug of Riley, a freelance graphic designer in the year 2025. Stranded forty-three years in the future, Michael must face a world that already knows his tragic history. But Riley fiercely refuses to let that history repeat. She offers him the anonymous, ordinary life he always craved, rebuilding his shattered confidence brick by brick and teaching him the radical concept of self-love. More importantly, she arms him with the ultimate weapon: the brutal truth. She gives him the exact names of the snakes hiding in his 1982 backyard, the upcoming betrayals, and the devastating tragedies he is destined to face. When the universe inevitably pulls him back, Michael is no longer the timid pop star terrified of his shadow. He is a king preparing to claim his throne, knowing exactly how to rewrite music history and what it takes to survive. But armed with the future, changing his fate might cost him the one person who taught him how to live.
