What a shame. This could have been the best of this week, but it's just unreadable. I'm not sure if it's the author or the translator, but there are just too many mistakes and inconsistencies. Here's a short list - Names are wrong multiple times - System is a radar, but then the card he got also has a radar? So it becomes confusing to know what he used. - MC never got even a white card because of a lack of money. Sister has a green card? - When monsters die they leave cards. MC kills a bunch of monsters and nothing? - MC can kill creatures and even run faster than a blue level tiger? Then why the heck didn't he go to that realm and capture cards before? To read this novel you would need to turn off your brain completely, or you would be distracted by rational thoughts...

How can they become countesses without their parents dying? As far as I can tell, they'll be heiresses forever...

Agreed. This is inconsistent with what the author had said previously about all beasts syncing their level...
