Cringy and awkward. Lastly show off

Just asking. Is the mc an idiot or a dumb one??? He basically wasted those creation coins. Although its not really my right to complain. But why is he really an idiot??

You know what I hate it. Because the MC is getting dumber and dumber as the story past. He should be more smart now that he is now a diamond tier but WOW it shock me more that he was just like a slave to the king. The story became bring at this point. He clearly was reminded by his future self to be stronger but all he's doing is pointless. He clearly have a high chance in taking on the king. Just by relying on his newly acquired weapons he can make himself invinsible. What's happening author. Your making the story boring as it goes. He should clearly focus on getting stronger. Why do I feel that his doing useless things even giving his enemies weapons that can be used to deal to him.
