I'm suprised this hasn't been reviewed yet. I've been binge watching chinese animes and this is one of the top series I've watched! It's got good plot and a conclusive ending. They could make a season 2 and explain in more depth the workings of the world but I think it's already a good place to end without much of a cliffhanger. The animation is also a bit better than the average chinese anime but not as good as King's Avatar or a few other ones but it's good enough that it doesn't effect the viewing experience. The characters are also pretty good and eachone is unique, they do show the backstory of each character (which actually kinda matters for the overall plot).
