Reborn in the Seventies After the Apocalypse: I Become a Mom, and My Brother Is the Male Lead's Rival

After her young son died in the apocalypse, Zhong Muran was so devastated that she fell into despair. In the end, she ended her life in a self-detonation. But to her surprise, she was reborn in the body of a woman abandoned by her husband. That was bad enough, but... why did she open her eyes to find a baby sleeping beside her? She... she had become a mother as soon as she transmigrated! What surprised her even more was that she seemed to have transmigrated into a book, and her family weren't even NPCs in it. They were just insignificant background characters... But since she'd ended up here, she had to put her second brother, who was destined to turn evil, on the road to success and make sure he didn't end up alone for the rest of his life. As for the husband who abandoned the original owner, there was no way she'd let him off the hook.
