Chen xing had the ability to reincarnate because she was given that ability by the matriach of the phoenix clan. At the start of the novel, it seemed as if that it was the ML that went back in time, but it was actually the MC, during the start, you can see how cute and innocent Chen Xing was, because she couldn't remember her past lives memories. Not sure what are the rules of her reincarnation, because it seems that she can either come back to life in the past, or right after she died. She died a lot in this novel, mostly by the hands of human cultivators, I despised them for it.

But the real truth was, he was the only person besides xiaobao who ever stood against the whole world to protect her, and every single time he would always die protecting her, made me want to cry just thinking about it.

Another thing is how upright he is which is rare, often times, ML in novels are written as cold blooded and cruel, but this ML will be the first to fight against injustice.

the mythical beast clan was said to love and care for their kind more than anything, yet despite knowing what the MC would face, they still chose to abandon her there so that she could be the tool to save them. And when she met them, they all said superficialcare words like " you have suffered", "I hope you find happiness" while they wouldn't hesitate to put her through those kind of sufferings again and again if it means their clan could survive.

her reincarnation ability and suffering was all calculated by the mythical beast clan for their own sake. Basically, the human cultivators, the mythical beasts, and even tiandao were her enemies.
