Review Detail of Klemantoni in Dragons Among Heroes

I've read till chapter 12 and there are a few problems that bothered me. First, the MC sometimes act impulsively and dumb. Second, usually systems are used to give a feeling of accomplishment to the readers when they see the visible improvement in the host's stats and power. The author didn't show us the MC's improvement... Third, the dialogs are weird and cringey. bye exp
