This novel is so slow

#1

I don’t get the idea why does the main character want to hide his strength and shock everyone after one month. So what if his cousin knew that he has been training? Wouldn’t it be better if the cousin knew and also train very hard but the hero still kick his ass after one month? I’m at the 80 chapter but there is still half a month left. I think It will take a few hundred chapters until the day finally comes. I started reading this because the ratings are very high but didn’t expect it to be this slow.
