While I quite enjoyed the main characters and the missions (especially Ouroboros), the rest of the novel was rather underwhelming. For exemple we never really learn how the Tianqiong system works???
The team dynamics are great (loved the confession scene), but individually we don’t know anything about the other teammates other beside very surface level character traits. 
I saw some people complaining about the underwhelming and predictable ending, but I actually didn’t mind it that much. At least it wasn’t a cliché revenge plot line.
