This chapter was so damn good. We got so many things from this. From Zoro being a descendant of Ryuma, to King's race finally being revealed and possibly being from the moon. Sanji's abilities can possibly be enhanced. Is there a connection with the Lunarian dna and Sanji? Could Judge have used that for Sanji? We'll see.
Also for all these threads out there about swordsmen, and hakimen, Shanks vs Mihawk. Oda has elaborated more with one of King's lines in this chapter. "Ive never understood why anyone would stick to traditional forms and techniques during a real battle." Zoro then acknowledged that King never claimed to be a swordsman. Just because you have a sword and use it during battle doesnt mean you are a swordsman. I think we can finally put this to rest.
