Actually a nice and funny panel.
Kabuki gag at finest, also they didn't laugh at Big mom attack but more like even sweating,make Zoro feat even greater since he cut these fireballs down.
As
@Ice devil slayer noticed, Luffy already bleeding with means we can expect more feats and attacks of the Yonkous. Seems like this going by a great fight chapter,it seems like our own provider didn't know more as usually. Their could be more crazy stuff in this chapter,Lance already hint twice something with open up the question what we gonna get in this chapter.
