Submitting to My Best Friend's Dad - Chapter 724 : Insomnia

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.

Pei Xian, who looks like the green tea and white moonlight of Big Boss in the book, was forced by Zhou the First Gongzi to kill his child and send to the villain Big Boss as a substitute lover. Pei Xian would rather die than submit that he jumped from the building to his death.

When Shanghai’s Great White Shark Si Yang was only 28 years old, he died of illness and transmigrated as the cowardly and timid cannon fodder Pei Xian, airboned in confusion on the scene of the jump off.

In Gu Han’s book, the villain Big Boss was beaten by half of the book by the male protagonist’s “wisdom reduction aura” and eventually the Big Boss’s company went bankrupt and he became depressed. Now he is reborn with a system called “concern and care for villain’s IQ”, and Pei Xian is the system’s battery. Gu Han needs him to be around all the time to charge before using the system.

Gu Han picks up the scheming boy, turns around mercilessly and goes upstairs….
