How to evaluate the role of Dan Tai Ember in the TV series "Long Moon Ember"?

First, as the first generation fiend, he was born in darkness and chaos and felt the negative dark emotions in the world. He chose to use his own bones as swords, wash marrow marks with his heart and use his eyes as crossbows. He wants to open the road of compassion, let the world return to chaos, and no longer distinguish between Qingming and chaos. Actually, he just wants someone to accompany him. He's so lonely. He listened to the evil in the world alone in a chaotic and dark place. Second, when Dan Tai Ember was a second-generation fiend, he began to understand some other emotions slowly. At that time, he just called out Li Susu's name and was hurt by Li Susu. Finally, Dan Tai Ember experienced three robberies. He understood the worldly desires and that he should love the whole life and be willing to sacrifice himself for the whole life. Therefore, I think the role of Dan Tai Ember is gradually full.
