Shang Qingyue, the second daughter of the Shang family, was famous throughout Zhaoyao for being a frail invalid who couldn't even harm a chicken. Yet one day, this young woman, who rarely ever left her room, suddenly disappeared. Her father was heartbroken, and even spent a fortune searching everywhere for her, but to no avail. Shang Qingyue had snuck out to look for her elder sister, who was investigating the enemy state's military situation. But no sooner had she escaped her home than she witnessed a murder and was forcibly taken into the Yunsha Sect, a notorious demonic cult of the martial world. No one could have guessed that Song Ziling, the Yunsha Sect's fearsome leader, was actually a frail young woman with no martial arts skills. What's more, she was also Zhaoyao's top candidate in the imperial examination that year! Meanwhile, Shang Hongling, who was surveying the border terrain with three thousand cavalrymen, was ambushed and captured by enemy forces. Forced to endure a hellish existence, she discovered that these soldiers were no ordinary troops: they were transformed bodies of the demons from Mount Zhaoyao.
