Apocalypse: The Day Before Nuclear Wastewater Was Dumped

[Apocalypse + nuclear wastewater + both reborn + System + special abilities + biological mutations + zombies]

“Japan will begin releasing nuclear wastewater as early as the 11th...”

Nie Tiyang opened her eyes and found herself back ten years in the past, on the day before the nuclear wastewater release.

She had also gained a System of Mass Slaughter. Once she accumulated one hundred million points, it would grant her any wish, no strings attached.

She blurted out, “Can you make Japan disappear completely?”

“Sure can~” the System replied cheerfully.

And so Nie Tiyang began her one-way journey of slaughtering zombies, only to unexpectedly meet someone else who had been reborn.

That person was also a big shot in her previous life: ruthless, taciturn, and able to kill without batting an eye, all while holding a tabby cat.

The two teamed up, sharing the same goal and the same convictions, and began slaughtering everything in sight.

But the more they killed, the more Nie Tiyang felt something was off. This person seemed to be getting clingy with her?
