Too bad I've read it too.., almost good actions shit I've read it

I'm so lost of manhwa to read, I've been searching through the "strong male lead" tags for weeks now and i'm in the boring part aka almost 200 I CAN'T FUCKING FIND ACTION, GOOD PLOT, NO HAREM, NO FUCKING ROMANCE, AND ACTUAL GOOD REVENGE. Just please give them to me (oh except old yk with long hair typa shit not into it at all)
