Review Detail of uflesh940 in Transmigrated as a Ghost

Dropped at chapter 14, mostly because I didn't really like how the main character had started developing. First of all, he decides to become a "jack of all trades, master of none", and learn fire and lightning magic instead of just focusing on the iron magic which he has an affinity for. Also, he's decided to go save the sister of the dead body he's possessing, which I can't really get behind.
