I've been trapped by this game for a long time. Know you're getting in a almost gacha service type of game, at least it's a pretty good one. A lot of content and hours of fun gameplay loop but still a time consuming gameplay loop as many other games. Not a lot of ads, and useful rewards with them, which is better than your average mobile game. Also very consistently updated.

TLDR; Service chinese mobile game that's better than many of the other monumental dogpile of chinese cheap games out there
