Read up to chapter 184 for now.
Sadly the MC gets blinded by power. Making 5-year olds from clan work hard. Using public military funds for the growth of his own personal forces and clan. Not only that, but also framing with a death sentence a quite strong loose cultivator who has not done anything wrong except refusing to bow to MC and become his lackey. Maybe in some jungle law cultivation novel that would seem normal, but in this one, there are rules set by a big sect in which families can't murder and plunder weaker families as they please if they don't break the rules and the big sect also made restrains to big families so that loose cultivators and weak families can live rather safely and have an opportunity to grow despite so many things being monopolized. MC's family survived for as many as hundreds of years pretty much only because these rules were in place - despite being in decline, the environment seems to be quite stable and relatively safe, at least for the last 10-20 years there have not been any beast or evil cultivator attacks against them.
As it is portrayed, MC does harm to others for no reason, seems like a tyrannical villain and a hypocrite.
There was a case where MC stole some families' business and one of the more desperate family head retaliated out of desperation - because the business was too important for him (his fleeting breakthrough opportunity depended on that). MC basically cut their line of income and then made them a scapegoat ,,to scare monkeys". Of course, the family was not some good-hearted family, but hey, it could be solved another way. Especially when, after 50-100 chapters this amount money was nothing in the eyes of MC..
When other big guys asked him to join them, they didn't threaten or oppress him or his clan. Even when he refused, they either gave gifts or just dropped the topic. But when MC gets refused, he ,,feels uncomfortable", ,,his face turns ugly" and so he frames the guy who didn't want to be his lackey into... death sentence. Of course it later turns out the guy was a spy, author's attempt to glorify MC I guess, but MC didn't know that when he framed the guy. If he wasn't a spy, then he would end up framed too..
There's also that thing with Izumo slaves (Japan?). Izumo mortal women are treated as if they were not human, and even their memories are wiped out. And then.. these women become integrated into enemy's country (MC's) as wives and concubines of mortal families in clans to give birth to children with spiritual roots and so on. Why treat them like slaves when they're integrated into your family and give birth to your clan's cultivators? What if her cultivator child learns what his mother went through and decides to go on a revenge spree? There are already many such novels where MC avenges his mother by wiping out such family....
