I wonder if you can reach lv 9x with exp on floor lower than 10 ( which is claimed to be 1-2x adventurers gound). And weapon/armor drop on those floor could withstand clashing from 9x equipments. And that 9x guy not even once underestimate his opponent. Nice idea but illogical story. If the MC ( mr.Minataur) died and respawn time after time, advanced to 11+ floor to get stronger, i could accept that but the story so far is a joke.
