Alright I'm going to review things that I appreciate in this series. I believe all series have their own pro & cons. It's just this one have some things that I need to emphasize.

1. The sibling relationship is gold
Both the sibling interaction A Fu-He Na or Luo Ge-Luo Ning is precious. They have their own way to protect each other. But sometimes the option is not right. Especially for A Fu-He Na, their story of brotherhood has a dynamic that it makes me touched, mad or sorry on them. Gonna appreciate them.

2. A touching side story
Aside from the demon brothers story, we got to see other story that really touches my heart like the story of Lu Li and his master, also the story of Luo Ning. Can't be helped but feel sorry & appreciate them. Kindness really touch people's heart.

3. Good chemistry of main lead
Honestly I kinda like the chemistry of Lu Li-Liu Shao they can be cute/funny at times. I also like the fact they trust each other. There's misunderstanding but thankfully it's not dragged. This is just personal opinion.

4. Great cooperation of Demon & Immortal
I like how this series has been teaming up between Demon & Immortal way early. It's unlike until the last minute finally we can see justice for demon. I think this series fight the prejudice of demon. Not all demon is bad thankfully they made it clear earlier.

5. Perfectly matched BGM arrangement to suits the mood.

6. It's not dragging for the first 20 eps? That's what I feel since I like fast paced story. The rest eps is fine for me. It's developing just slowly later on.

Lastly, there's some things that need improvement like side characters' acting on some parts but so far it's fine. I don't want to leave comment that can ruins someone first impressions. Have fun watching!
