@es_kan Drop the manga cause you will never understand much. 100 chapters in the level of mind battles are far above any other series out there while the fighting is the minority. This manga is too good for you, go back to reading crappy manga.
100 Chapters in would be right around the end of the Labyrinth arc, right? I'm not sure how one would think about the manga as focused on strong people beating each other up instead of gambling and games at that point.
I think you are missing the point of this manga. Early on in the manga it was pointed out that winning a gamble without the power to obtain wat you won is pointless. It was also pointless if you won and got the money but ended up dead because your opponent had grudges on you and want you dead.
Because of that, power and violence is essential parts of the gambling itself.
It also makes usogui unique compared to other gambling manga where everything is over without any consequences after you win a game
