Review Detail of InternetSaint in Fox in an inverted world

It started out very good but around chapter 80 the story just gets nonsensical and directionless. There is no goal or reason for the things that the MC does. He for example helps some human because that human has heard of a legend that MAYBE there is a way to help is parents and for that reason alone he goes on a suicide and the MC who doesn't even know the guy or has any connection and has way more important things to do during that time, for no reason suddenly decides to risk everything and follows and carries that guy and constantly risks his life just so they can go to even more dangerous areas of a pocked dimension.
