Transmigrated to the 80s with a Lucky Koi System

While others transmigrate into lavish estates and noble families, Chen Yao wakes up in a dirt-poor mountain village in 1980s China—no running water, no electricity, just endless hardship. But she's not completely defenseless: a mysterious Lucky Koi System awakens with her, turning misfortune into opportunity. With golden-finger luck on her side, Chen Yao is determined to transform her fate, build a fortune from scratch, and prove that even in the humblest circumstances, a girl with a system can rewrite her destiny.
