the author could have made this an interesting manga. all he had to do was when the big bad launched the beam it stored 1, and only 1, from that blast then when blasted again it went up to 2. he then uses 1 to get rid of the big bad and has a secret weapon for later. the gold is a freebee manga never care too much about consistency in money but nooooo author cant let HIS masturbatory power fantasy have some level of reasonability, so instead MC is going to get effectively infinite stacks of the beam attack, then hes going to find a healing circle and instead of grabbing the FRIGGING CIRCLE he going to grab effectively infinite stacks of healing, also MC is going to find a bunch of legendary gear, and as a bonus rotten cherry on this shit-sty hes going to walk outside and find endless amounts of fruit that permanently boost his stats!
trash manga is trash
