Level Up Legacy - Chapter 1421: Oaths and Promises

Kai’s life was small—coffee-stained mornings, cracked recipes, and a system in his head that tweaked toasters and dough like it was nothing. Then the sky shattered. Aliens—Skraiths, jagged and brutal—invaded, tearing his city apart with green-glowing weapons and relentless claws. Superhumans rose to fight back, fire and lightning blazing through the chaos, but Kai’s world crumbled with them.Hiding in his apartment, Kai stumbles on blood—human and alien, smeared on his wall after a superhuman battle. His system, once just a tinker’s tool, awakens, offering him a choice: mimic their powers, temporary and wild, through the blood itself. Desperate, he takes it—stealing pyrokinesis, then electrokinesis, then kinetic energy, each power burning through him, fading fast. But it’s not enough. Armed with a humming Skraith weapon and a body tougher from alien blood, Kai joins a ragtag crew of enhanced fighters—Liv, Rylan, Jace, and Tucker—scraping to survive in a warzone where every shadow hides death.As Skraiths swarm and the city burns, Kai’s system pushes him deeper, analyzing, integrating, crafting minor enhancements—durability, strength, sparks of power that could make him a target or a savior. Government factions, rogue scientists, and the aliens themselves start sniffing around, drawn to his strange tech and blood-stolen abilities. By the time Kai crafts his first super-powered enhancement—an artificial strength boost—he’s no longer just a tinkerer. He’s on the edge of something bigger, something dangerous, where blood and sparks could forge a hero—or break him entirely.In a world unraveling, Kai’s fight for survival becomes a desperate race to master his system, outrun the Skraiths, and confront the truth: the power he’s chasing might destroy him—or remake the world.

A character with extreme difficulty and the worst performance, Baek Yu-Seol was considered tr*sh in the game because he couldn’t use magic in a fantasy world where everyone else could.

However…

[Due to the wrong ending, 90% of Aether World has been destroyed.] [Please reach the ‘True Ending.’]

Suddenly, those words echoed in my mind before I was transmigrated to the Aether World.

[You can use the skill ‘Flash’.]

“Why did I possess this character?”

Flash was the only magic skill I was given.

Surviving in Stella Academy where many genius mages ran rampant, I became the notorious Flash Mage.

【Mr. Lin Wife's Love Story】“Boss, in one minute, your wife has scratched a limited edition sports car while driving.” “What, has the wife been hurt?” “No.” “That's good, you can directly charge the expenses of the car to my account.

Damn, with things like this, why did she even get married: “Lin Mubai, I want a divorce.”(This story doesn't involve any third or fourth parties, even if one or two pop-up sometimes, they are just cannon fodder)

– Question: “What is scarier than the personal experience of transmigrating into a horror movie?”

Anonymous: “Transmigrating into a movie you’ve never seen before.”

Anonymous reply: “You sure? Can you be sure your dad isn’t a murderer? Can you be certain your spouse isn’t out to kill you for insurance money? Can you even be certain there isn’t any hidden lethal weapon in your son’s lunchbox? The scariest thing is that you have never seen this movie before so, you have absolutely no idea of any ‘surprise’ that awaits you ahead!”

Hence, this novel is also called .

A line to sum it up: The female lead transmigrates into various movie adaptations of real stories, and conquers the audience.
