What? A Secret Agent Transmigrates to the Countryside in the 1970S with a Pocket Dimension

[Period setting + sent to the countryside + face-slapping + putting scumbags in their place + space + military marriage + real heiress + strong female lead + sharp tongue + feel-good revenge] [Rewritten synopsis] While carrying out a top-secret mission, agent Su Ruotong is betrayed by both her closest teammates and the enemy forces, who join hands to hunt her down. With nowhere left to turn, she detonates a grenade, choosing to die alongside her enemies. When she opens her eyes again, her soul has transmigrated into the body of a girl with the same name in the 1970s. The original girl's life is a living nightmare. The fake heiress, Su Ruoxue, manipulates her biological parents with her sweet, innocent act, while her older brother secretly alters the assignment paperwork to send her to the countryside. Her adoptive parents treat her like dirt, beating and berating her at every turn. Cornered from both sides, the original girl takes her own life. At that very moment, Su Ruotong's soul forcefully takes over her body. How could a top agent let petty nobodies get away with this? With a cold laugh, she tears away Su Ruoxue's false facade using ruthless methods, then grinds the fake innocent and the scheming "family" behind her into the dirt. After stripping her enemies of every last possession, she heads to the countryside with a fortune in hand. There, in the middle of nowhere, she meets the man who makes her heart race: Xiao Baiyi, a rising star in the military. "Comrade Su, I've applied for a marital home in the family compound." The man slaps a deployment report stamped in bright red onto the table. His long fingers suddenly close around her wrist. "Now, you can call me Mr. Xiao."
