My 100th Rebirth a day before the Apocalypse

Kisha Aldens is a normal office worker with average earnings, not until she suddenly sees a system countdown in front of her. Her mind suddenly received a prompt warning about the apocalypse and urged her to integrate with the system to assist her with her survival.”Have I overworked myself again?” She thought while pinching the bridge of her nose. She blinked a few more times but the system interface is still there.Little did she know that this system would be her last lifeline in the upcoming apocalypse where human morals would be the lowest, trust is only a word and betrayal could happen in the blink of an eye.A naive person like her had to learn her lesson the hard way on how to survive and navigate in the zombie-infested world. And the worst part, she had to die 99 times to harden her heart and learn how to read the human heart. How will her 100th time be different from the previous lives, will she survive this time?And will survival be her only problem in the heart of the Apocalypse? No, there was a deeper scheme in play which she has to uncover moving forward.
