Need help tracking down a panel in a chapter

I cant remember if this panel happens during the finale of the hell train, leading up to the final fight with karakas, or sometime after. Baam pretty much unlocks/starts understanding a new power he got, and so he visualizes it as if hes drawing a straight line in blue. I want to say he said something along the lines of "something so simple can still be powerful". Did I hallucinate this or does anyone happen to know what chapter/panel this happened in? This is for the webtoon btw. Thanks for your help
