Review Detail of Phantom_X143 in I Maximize My Item-dropping Rate

MC was a bit of a coward in the first few chapters.MC starts killing everyone except his sect people in any exploration( a very ridiculous bottom-line that makes no sense). Ok, still I could read past this but what I couldn't stand was why did he feel a responsibility over his sect?( another ridiculous reason just because he got some ancestral artifact of the sect.) At this point, the author just wants to add some baggage to the MC to make him have a weak point that I am sure will be exploited later.
