The Ice-Cold Demon Lord × Cute Junior Sister with Super High Strength Value
Yue Xiyun, a girl from another world, died in real life and was selected by the system as a defender to travel through an ancient bloody novel "Protect the Heart" that she read in high school.
The main villain in the original text, Ye Yinhan, deviated from the trajectory of the original text. After obtaining the world-destroying artifact, the entire world of cultivation was devastated. The male and female protagonists were supposed to be a sweet couple, but the two turned against each other and fought each other. The plot was completely confusing.
The system then brought Yue Xiyun back to the beginning of everything, and as a maintainer allowed the original plot to proceed smoothly.
After that, Yue Xiyun started a miserable life of fighting monsters and upgrading, taking care of the relationship between the male and female protagonists, and conquering the villain.
Concept: Don't think that the cutie is very strong, he is actually super strong!
