The writing is more "serious" (?). There are basically no good people in the demon world (the proportion of bad guys is as high as 99.99%, Pure evil forces), and as villains, the combat power of the demons is also set very high, so there are more characters who die.
Lian Xin was originally an ordinary child living a happy life in the small Peach Blossom Village in the human world. Once the demons invaded, her relatives all died in the disaster. She lost her home and family, and she has been like a duck on the water ever since...
