Help! The Apocalypse Came, and I Transmigrated to the 1960s

[Period Setting + Transmigrate into a Book + Spatial Dimension + Check-In System]

When the apocalypse arrived, Su Li awakened a spatial ability, but before she could make her mark in the end times,

she unexpectedly transmigrated to the 1960s and became the apple of her family's eye.

She had only just accepted that she had transmigrated to the 1960s when she discovered that she was actually the cannon-fodder villain in a book.

But who was the person who saved her right after she transmigrated?

Why was the gaze of the young man living in the cowshed becoming more and more peculiar?

The military officer who saved her kept appearing by her side, drawing closer and closer.
