I Must've Slept Too Hard: I Woke Up and My Best Friend Had Turned into a Zombie

[No CP] [No System] [Pure Apocalypse] [No Superpowers, Only Zombie Cores That Increase Physical Strength] [Team Survival] [Thrilling Escape] [The blurb is weak, so read the exciting story instead]

She woke with a start, and the apocalypse had arrived.

Zombies, despair, and fleeing for her life.

To survive, Zhao Jie had no choice but to harden her heart.

She knew that in the apocalypse, she herself was her own god. Outsiders could never be relied upon.

Without a hard heart, you could never stand firm.

She began building her own team, killing zombies to collect their cores, and killing self-righteous do-gooders, all to establish her own human civilization in the apocalypse.
