My Foolish Little Sister Is a Yandere, and Her Three Brothers Dote on Her

[The female lead has a pocket dimension, 1vN, the main cast looks out for their own interests and protects their own, no CP for now, readers who judge characters by modern standards proceed with caution, lighthearted, entirely handwritten novel]

Chu Ning spent over a decade surviving the zombie apocalypse, then transmigrated to ancient times as a mentally disabled child and gained three powerful big brothers for free.

The eldest brother is the most ruthless mercenary of the nuclear-war apocalypse, decisive and a master fighter.

The second brother is the greatest engineer of the mechanical apocalypse. He never forgets anything he sees and can build bombs.

The third brother is the craftiest merchant of the alien-beast apocalypse, glib-tongued and skilled at cheating and swindling.

At last, four lonely, bloodthirsty souls have a stable life.

She thought transmigrating meant settling into a peaceful retirement, but trouble keeps coming, buzzing around like flies!

It turns out they have other identities?

Anyone who gets in the way of their comfortable retirement is in for a bad time!

When the siblings are in a good mood, their enemies die quickly. When they're in a bad mood, they make sure their enemies can't even die when they want to.

In public, each one is more beautiful and kind-hearted than the last.

In private, they're all vicious and cruel. Tearing villains limb from limb is routine. The sweetest-looking one is the most brutal, but nobody knows?

"Big Brother, walking is so tiring. Little Bao's feet hurt!"

"Second Brother, it's so cold outside. Little Bao's bed is cold!"

"Third Brother, I'm hungry. Little Bao wants meat!"

Her brothers quickly put down their butcher's knives to take care of their little sister first.

Chu Ning's wish for transmigrating is simple: keep her secret identity hidden, stockpile supplies, and raise her brothers.

Her brothers' wish: protect their little sister's secret identity.
