The 1970s: Space Sent Me a Soldier Boyfriend

[Transmigrate into a book + military marriage + sweet romance + space + devoted couple + wish fulfillment] Xia Li, a powerhouse with both psychic and space abilities in the Apocalypse, has transmigrated into a book. What? This is where I was originally from! What? The Heibai Wuchang have even given me a space as a bonus! Xia Li immediately decides to lie flat. She has a family and a space, and there are no zombies. This world is wonderful. Except... why does this space let people slip in? Still, the soldier who slipped in is tall, handsome, and long-legged. He can earn money, support a family, and do chores, and he even proposed to her! W-well, how could she refuse? So it turns out that spaces really do come with husbands.

(P.S. The male lead is a soldier. At first, he appears on a mission disguised as a mail carrier. His identity will be revealed later~)
