I've read many novels. Many of those novels I learned were the same novel dressed up differently; linear progression, face slapping half retarded young masters, and harem building score boarding with no sensuality. Your novel is different. A breath of fresh air in China air pollution.
Story is good but it's boring and writing is also part of reason makes it boring idk why though.
But one of the reason I identified is MC doesn't have a goal to work towards it. People complain most of wuxia novels being created from same mold but they do read atleast 100+ chapters before saying that. Thing abt those novels is that they clearly establish early on what MC wants to do or why he wants to get stronger (no matter how much of cliche that reason to be).
Your MC is just following the tide that too unremarkably.
So only things tied readers to novel is smut scene or action/fight. Nobody interested in politics tbh.
Personally I think webnovel readers is mostly kids and teens with quite a lot of girls considering the top rankings choice of original novels, so yeah it is no wonder this novel is in a bad day for long
Thanks for the hard work
