please help what chap is this in the novel?

found it chap 341 in the novel ლ(´ڡ`ლ)

you might wanna read before that. there's a whole arc they skipped, thats really important and why these old fools actually came. not sure if theyre just flipping the order, but youll miss a pretty good arc if u skip to this section

roughly around 249 i think but i cant be sure

257!
