Back at PH when Zoro Cut Monet in half we get an explanation from Tashigi perspective on what Zoro attack did to Monet, He didn't use any Haki just using a Demon Aura an overwhelmed strength to terrify Monet.
So I wondered if we got explanation in summary or Raws later like Lucci saying his entire body and soul was freeze and we got a panel his chest left a freeze cut mark like what Nasujuro did to Pasicfista or Jimbei commenting the aftermath of the fight resulting cold atmosphere something like that, but if we didn't get any of that 3 weeks is really a long week for Zoro Fans.
Regardless,Zoro still Win the fight, probably not a Huge W for Zoro, but Nasujuro is next in coastline of egghead so Zoro might fight him soon....
