Not recommended , unless you're very bored.
Seems like a summary of events, bloated a bit (Like other chinese novels), add some more things, and sewed together.
At least the author researched things, some obscure things.
Though as is with this genre, plagiarism is to be expected. Lots of it.
And face-slapping is normal in this story; MC does/offer something, others reject him, MC does another thing, and others be like 'Damn, shouldn't provoke/reject him'.
And dialogue is rare.
As for harem... Well, its like a casual fling; no serious relationship yet. And don't expect detailed romance scenes. Chinese novel don't have it.
Oh, and translation quality. They're readable. And based on other reviews, translator is doing some editing. Though will not be the same quality if the original is english.
Some wordings are weird, it's more likely because the original version is like that. Like, lost in translation, but make sense in the original language kind of thing
