Yeah, quite a revelation. How did Diao get chainmail? That's usually reserved for the ultra-rich nobles, and she is from a poor village. Btw, women wearing chainmail is often seen in Chinese old setting series/movies. Which reminds me, it is now confirmed that Diao is female, with the dress and Bi's reaction to undressing her (how will she get married now? He has "shamed" her.
)
I know it is shounen, but how the heck did Xin move again? I know if I was in that state, at most, I can probably only wriggle my fingers slowly.
Overall, nice episode, but bad CGI.
