MC is kind hearted, attached to family. Couldn't even kill his already dead zombie cousin without hesitating. This emotional intelligence seems like a red flag, MC will probably make many mistake while being emotionally.
As story goes on.. MC is becoming more like eunuch. MC knows the plot but he is not scheming anything to recruit powerful heroine to his peak. Liu girl who is reincarnation also came by chance, MC should have tried to recruit her but he is being extremely passive.
MC has beginning to act like Dumb Guy which can't understand hint from girls, just like his predecessor whom he was complaining at the beginning of novel.
MC is nurturing Li Cangxuan even if that is to cause trouble to Heavenly Dao. Don't like that. This move seems unnecessary.
