Lin En transmigrated into a magical world that resembled medieval Europe but had the power of magic.Here, magic could affect and control basic particles, which was based on scientific theories that served as magic formulas!The wizards, who were actually scientists, were struggling to explore the truth of the world under the chase and blockade of the church. Lin En’s arrival sparked a renaissance of the alternate world…The white phosphorus fire, known as the Flame of Hell, the liquid nitrogen field of extreme cold, and the resonance frequency that kills without a trace… A few years later, the Holy See gathered all countries to the city, known as the legendary wizard, the pioneer of magic Lynn under the gaze of a group of wizards, wrote down the mass energy equation known as the ladder of God by later generations! Lynn looked around the crowd and said nonchalantly. “Mass and energy are interchangeable, and based on this theory, I have developed a powerful forbidden curse… It’s called — “The Big Nuke!”We will re-examine the world from the perspective of magic, where science is magic, and magic is science!

Guys here is my pitch.....In the sprawling world of fantasy, we’ve often been treated to tales of heroes reincarnated with divine blessings, legendary powers, or cheat-like abilities, thrust into magical lands as shining saviors—or chaotic terrors. But what happens when the very concept of reincarnation becomes a curse? When the divine boon is a big fat joke, and the “cheat system” doesn’t quite… cheat?Enter John, the unluckiest reincarnate. Blessed by a god and thrust into a fantasy world, he dreams of glory, power, and adventure—only to wake up as a normal, utterly powerless bird. Not a mythical phoenix, not an ancient thunder eagle. Just… a bird.To make matters worse, this world is no ordinary realm. It's a land scarred by the devastating legacies of past isekai’d heroes and villains, whose reckless exploits piled skeletons into mountains and turned their cheats into harbingers of chaos. Fed up with these unruly intruders, the ancients of the realm banded together to create a world-shaking seal: all reincarnated souls are trapped in the bodies of harmless animals, confined to isolated sanctuaries that function more like fantasy zoos.Here’s the twist: this isn’t mercy. It’s a resource grab. The powerful beast tamers of this realm have turned these reincarnated souls into exotic pets, prized for their cheat-like potential.John finds himself at the bottom of the food chain in every sense. His cheat doesn’t work. His human form is gone. And his world is filled with predatory cultivators who see him as either a snack or a tool.But John isn’t one to give up so easily. What starts as despair quickly turns into cunning survival. With wings and wit as his only tools, John must navigate layers of misfortune, dodge fate’s sharp talons, and cheat his way through a world determined to keep him grounded.Get ready to join John on a wildly unconventional journey—one where reincarnation isn’t a ticket to greatness, but a death sentence he’s determined to rewrite. His story is one of humor, wit, and persistence, as he explores a world where he is the joke and his survival is the punchline.Main tags: reincarnation/isekai, beast taming cultivation system, comedy, action, adventure.Of course No-harem!
