What chapter of the novel does chapter 195 manga equal to?
same as the title
Manga chapter 183 would be the newest translated chapter of novel 786 (Pill King Gu He joining alliance, getting note about Hall of Souls).
But i'd still recommend reading it from the beggining
at least u would kill some time till they translate it all the way through (at current pace it should occur at july 2018 [26th if my math have no flaws]).
