My mom ran an exclusive underground fertility clinic. Her dark red serum smelled like rotting blood, yet the rich still lined up with massive checks for her "perfect designer embryos."
I’d watch her lock desperate young surrogates into a soundproof room. A few minutes later, the whole floor would shake.
Strangely, when the girls stumbled back out—looking entirely drained and aged by years—they would weep and kiss my mom’s hands in gratitude.
It never made sense to me.
Until the day I saw a pitch-black mass frantically clawing just beneath a surrogate's flat stomach.
I finally knew what kind of "embryos" my mom was actually planting inside them.

Seven days before the doomsday outbreak, the wild weeds by the road spoke to me: The zombies are coming.
I rushed home, intending to take my fiancée and flee for our lives.
But outside the door, I overheard her plotting with her boss on the sofa, scheming to drain all my wealth.
"He’s just an orphan with no family or connections. No one would care even if he dies."
I didn’t push the door open.
Instead, I quietly cashed out all my assets overnight and built an impenetrable island fortress without delay.
Seven days later, the zombie hordes surrounded the city.
She and her entire family were chased by the monsters, covered in blood and mangled.
They knelt frantically kowtowing and begging for help right outside my explosion-proof gate.
I coldly locked the door tight.
"You were right," I said. "No one really cares if you die. Just go in peace."
