- Description from Novelupdates

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.

In the legends that were told, ten thousand years ago the twelve demon kings wreaked havoc upon the world, almost completely destroying it. Ten thousand years later, the late arriving Bella discovered that she had been screwed over by her reincarnation, the ranks of the Saviors are already filled and she has to change teams in order to pass the days. Having her gender changed into a beautiful girl… she endured that, not being able to join the righteous side and obtain cheat abilities… she endured, but what she could not endure, was that the world that she had transmigrated to was toxic beyond belief. No one here does their rightful jobs properly, be they heroes, demon kings, or creator gods… in fact, Bella felt as if they all had also started with the wrong faction!

Who made the rule that a woman can't be the first to confess her feelings to a man?

If there was one, then it didn't matter to this young woman.

In order to escape from her stepmother and stepsister, Zhang Liling sought help from Mr. Fang, a Business Mogul, specially invited to take her department on Business Management, and she was rejected because of her absurd request.

But through his Personal assistant, she managed to cunningly secure a home-work contract and moved into his villa.

A few weeks of living together as a Boss and Employee was enough time for Mr. Fang to see all the crazy sides of Zhang Liling and also for her to discover his health secret, hyperosmia. But the irony of her scent not affecting him baffled her.

Mr. Fang not being used to Zhang Liling’s unrestrained behavior and coupled with the rumors about them threatened to throw her out of his villa. But when she finally left, he began to long for her return.

At last, Zhang Liling returned. To others, she was a different person, but to Mr. Fang, she was the same feisty woman he has always known.

Together as a couple, Zhang Liling and Mr. Fang unmasked her stepmother’s deep dirty secret that will threaten the Zhang Family’s reputation.

EXCERPT

“Mr. Fang, do you accept stray cats?” Zhang Liling asked a little breathlessly as a layer of sweat formed on her forehead. She had just run over in other to catch up with him.

Mr. Fang paused briefly in his steps and turned to give her a good glance after adjusting his reading glasses. “You look like one,” he said in a deep voice before continuing in his steps.

How could Zhang Liling let him leave like that when it was a matter of urgency? She quickly chased after him and yelled, “Mr. Fang, you really have to take this stray cat in.”

“I don't accept stray cats, I only accept humans,”Mr. Fang replied as a slight smile turned up on his face.
