"Technology changes life, making the world a better place." Firmly believing this statement, Li Er died from nuclear radiation and began his journey across different worlds-- "It's not me who is wrong, it's the world. Let's start by taking down Arasaka." "Impressive Cyber Prosthetics, good thing my Cybertron Prosthetics are not bad either."

(Currently being revised so the story may be incoherent) "Knowledge, There you are! We need to do this quickly before the other gods notice." Valor says as he motions for her to approach. "I'm surprised you agreed to help with this." Gluttony adds with a cruel smile. "I never would have thought the God of Knowledge would be the one to give us aid." Knowledge mearly nods at his words. "Now, this is it! That crazy bat from the far continent has made some crazy monsters before but this one is the cream of the crop. Fully capable of self-evolution and self-replication. It can breed a whole army of different monsters by gathering the essence of other lifeforms!" Valor says as he points to a large egg on the ground. She nods again. "You know, I thought you'd be as excited as I am with this? Endless war and power; we'll have full control of the system once this thing begins its rampage." Knowledge raises her hands in the air and shakes them unenthusiastically. "As sarcastic as ever I see. Well, whatever. Place your hand hand here and help us with the seal." She does as she is told and a huge beam of light descends upon the egg; but her attention is elsewhere. Using the ceremony as a distraction, Knowledge brings lost souls from other worlds and implants them in unsuspecting inhabitants. She can see it. Tiny seeds of change have been sewn.

Phillip was the CTO of the largest mechanical engineering firm in the world. One morning, on his way to work, he died in an accident—only to awaken in an alternate Earth as the third son of the Duke of Wellington in the United Kingdom. But this new world was devoid of modern technology. There was no indoor plumbing, no electricity, no power grids, no appliances, transportation still relied on horse-drawn carriages. To a mechanical engineering genius, living without these conveniences was unbearable. If they didn’t exist, he would build them! Yet innovation never comes without cost. As Phillip begins introducing modern technology, he finds himself entangled in webs of politics and conspiracy. How will he protect himself from nobles who seek to use him for their own ambitions?

The story follows Chrono, the main protagonist who was once an accomplished physics professor. He is reborn into a world of fantasy that does not conform to the same principles as earth. The journey start from his infant stage showing various decisions he makes that may be influenced by his previous knowledge

If motion can change... then so can I.” Luma never meant to chase the wind—until it whispered back. When a mysterious traveler drops a scroll with cryptic truths and vanishes into the trees, her world of ordinary village paths and riverbend games cracks open to a universe ruled not by magic, but by the laws of nature itself. In a realm where physics and reality intertwine, Luma finds herself entangled in a journey that will test her courage, intelligence, and the very shape of her soul. Alongside Elder Ion—her enigmatic mentor who speaks in riddles and revelations—she faces robed figures who vanish into thin air, machines that run on unseen forces, and truths that fracture everything she thought was real. > Action explodes when the Spire’s Hall of Equilibrium is torn apart by an unseen wave of energy, scattering its scholars and nearly ending Ion’s life. In the Crimson Wastes, Luma uses Newton's laws to counterbalance a collapsing bridge, dragging an unconscious Nico to safety. And in a heart-stopping confrontation at the Bridge of Laws, she calculates her own fall mid-air—turning gravity into her weapon. Through every step, Luma grows—not just in knowledge, but in fire. "I don’t want to control the world. I want to understand it. That’s the difference between us." The Realm of Physis is a science fantasy saga where discovery becomes destiny. Each chapter pulses with tension, warmth, humor, and the power of thinking deeply in a world that punishes curiosity. Because when understanding becomes rebellion… Even gravity must answer to will. discord @gabfred4_38225

So, Gen Chol is your average civil engineering dropout except, you know, he's dead. One minute he's failing his dad's legacy, the next he's getting pancaked by a steel beam kun and waking up in a world that runs on magic and monsters instead of concrete and steel. But here's the thing about Gen: he's got a stubborn streak a mile wide and a promise to his old man that he can't shake. So when he figures out that this fantasy world's real estate market has one hell of a fixer-upper, the literal most dangerous continent on the map he sees as Prime Real estate Cue the shenanigans. There are fights with creatures that definitely didn't sign a zoning permit, romantic entanglements that complicate his foundation work, and a whole lot of improvising because nobody here knows what reinforced concrete is. Gen's trying to construct a kingdom from scratch using engineering know-how, questionable diplomacy, and more luck than any dead college kid deserves. Will he actually pull it off? Or is this just a spectacularly elaborate way to die twice? Guess you'll have to read to find out.

He’s not a mage. He’s a physicist. When MIT quantum expert Alan Chen wakes up in a world ruled by magic, he doesn’t panic—he builds. Soundwaves to shatter spells. Electromagnetism to bend lightning. While sorcerers chant, he calculates. But the deeper he digs, the more he finds: this world’s “magic” hides equations, lies—and something watching from the void. He came to survive. Now he’s rewriting the laws of reality. Science isn’t dead here. It’s just getting started.

"You have previously been told that the way of creating mana particles is by assimilating with the universe... Your thoughts and wills interact with what has been commonly called dark energy, and the result is the creation of VM particles." I nodded. "Well, that's not exactly right." That sentence alarmed the entire class. Mages improved by understanding more of the world, and therefore they have to follow the scientific method and basic rationality, liking it or not. Believing in a false theory should not actually yield any significant results as far as magic goes... It's impossible to believe we had been seeing things wrongly this entire time. And worse, it could disrupt the foundations of magic that we had built over time. The professor patiently waited for the class to calm down before resuming. "That is indeed how you create mana particles, there's nothing wrong about that. However, VM particles are NOT the only type of particle that can be produced from dark energy interactions." ""Wha-!?"" "How is that even-?" A ruckus exploded once again. I could feel my naturally producing virtual particles flickering in and out of existence, as I lost control of their production. I reckon my reaction should have been one of the strongest in the class, given my degree of faith in that particular professor. The majority would only believe a disruptive theory when they saw it with their own eyes, as a protective measure against falsehoods and... side effects like mine. I temporarily stopped my unstable radiation of mana and focused on the issue at hand. The woman continued: "There are, in fact, different ways of reaching the same place. In this case, different thoughts and wills that can interact with dark energy. The ancients called it the different Daos." Some quick assumptions revealed the logic in her words. Things were starting to get acceptable, magic-wise. "That also means... that there are other ways of creating worldly interactions that would otherwise look like magic, but that aren't actually magic. At least not how we know it." Wait a second... "...And yet, the general populace call it magic none the wise." My VM particles started to quickly flicker and shimmer. "In fact, the history books call it magic, too. However, there have been many of names for this sort of... miracle. Among them..." I broke out in cold sweat. "Divine Intervention, Power of Faith, Sword Intent, Bloodlust, Killing Intent, Fear of Death..." A tense atmosphere pervailed the room. "...Those are all proven states of will that can interact with dark energy. And each and every one of their interactions differ from one another, even if just slightly." I felt my connection to magic being cut off in that moment. "You have all committed a grave mistake. To assume that our 'Path' was the only one that led to knowledge and power is to discard the very first lesson I gave you." I gulped dry. I couldn't help but feel very vulnerable at that moment, especially because her words were correct in their entirety. "In this class, I will teach you about the other paths to power. And teach you how to defend yourselves against them, so this sort of thing does not happen twice. Follow me to the practice field!"

Betrayed by humanity orphan child Adam is reincarnated into another world and forced to share a soul with the devil, luckily he was also blessed with a system that lets him manipulate the physics of that world.
