Its a bunch of mini stories/snippets of their daily lives that kind of has an overarching plot. As you get closer to the newer chapters you'll start to see that something has happened, we just dont know what other than speculation.
If you are in the very first like 200 chapters, I dont think Old Xian had any idea what to do with the story itself so its just kind of random until the story art changed and it started gaining traction/popularity back in like 2015 ish. Although all of Old Xian works follow the same format so yuh.....
Honestly there never is a direct plot line or chapter i can direct you too. If you have ever seen/read Gintama, its a lot like that. You have filler upon filler and maybe one chapter sprinkled here and there where it starts forming an overall "plot". I would say stick with it and power through because once you see He Tian and Lil Mo introduced, thats when its starts picking up traction

I had.always seen this but i thought of reading this today and i genuinely dont understand what is this? Is it like a continous normal story or just a bunch of mini stories?
