-Even though the MC is part of one of the 8 great clans and just so happens to be the son of the patriarch of the clan he is as poor as a street urchin
-His mother who is an elder of a sect and father patriarch of a great clan don't give sh*t about him.
-And it mentions that people from that great clans can afford good cultivation resources but he who has an elder for a mother and great clan patriarch for a father can't afford it.
-If he was a cripple and nobody in his family cared about him it would have made more sense, but no just because he has a poor aptitude he is labeled trash and even his parents don't care about him.
-People from great clans can 'walk sideways' but he was still bullied by other clan members so they gave no face to his parents but they never care about it which is stupid for a Xianxia novel where Face means a lot.
-his mother doesn't give sh*t about him from what it I read so far but he doesn't want to let his mother down which makes no sense.
-His only cheat is his comprehension but other characters have good it too.
-the transported from an other world doesn't make sense because none of our world sense is put into place.
about the dog Hui Tai Lang getting kicked around by the main character, its mentioned that because the dog ate the demon lords arm it has trouble absorbing the arm and it would have died if not for being kicked around and its not like the dog suffers when its kicked it enjoys it (it's a masochist dog) . And about killing people left and right that is written above, the world is a place where kill or get killed so he chose kill.
