Are Even Random Cultivators This Strong?

Chen Xiaoman had one simple dream: live peacefully in ancient times, use her medical skills to help people, and guide her brother to success. But when a chance rescue on a mountain goes sideways, she realizes the horrifying truth—she hasn't transmigrated to a normal historical world, but into a cultivation realm straight out of a harem novel! Worse yet, she's just a background character while destiny keeps shoving her into the paths of overpowered protagonists fighting over legendary treasures. Can a nobody survive when even random passersby are ridiculously strong?
