A Psycho in the Apocalypse, Reborn in 1990 to Marry a Fool

Song Lan, a deranged female warrior from a nomadic tribe in the apocalypse, was forced to leap off a cliff by a high-level zombie while trying to save her people.

When she opened her eyes again, she had become the deranged village bully of a tiny mountain village in Earth's ancient past.

She was also tied up and married off to a fool from the same village.

She thought her situation was awful from the start, but who could have expected such a surprise?

The fool was actually a superhuman with an IQ of over 230.

Sell him to an apocalyptic corporation, and she could enjoy a lifetime of wealth and luxury.

Main Quest: Wait for the time tunnel to open, then sell the "fool" to an apocalyptic corporation.

Side Quest: Hunt wild creatures, grow vegetables, and enjoy a leisurely life.

The plan sounds wonderful, but...

[The time tunnel just won't open, no matter how long she waits!]

[The fool keeps getting stronger and has actually been taken by the government to make weapons.]

[Life as a tyrant in the countryside is so great. Does she really have to return to the apocalypse?]

[Why does she feel so sick? Fuck, she's pregnant with the fool's child!]
