Is chapter 66 a recaps and prologue put together cuz what was that???

Yes, what you saw is what you see

there are actually 2 chapters released today (66 and 67), and a separate s3 teaser chapter (65.5), but 65.5 was mistakenly tagged as 66, and the real chapter 66 was tagged as ch 67. we'll probably get the real translated chapter 67 later
