Did you skip the first 50 chapters of Wano? Zoro's entire storyline revolved around Hiyori, Yasuie and Toko, all whom have a strong connection to Orochi.
Hiyori will try heal Zoro but Orochi will find her. She'll try kill him but fail. Then Zoro will use his last bit of strength to kill him and avenge Yasuie, free Hiyori and free Wano.
Oda doesn't repeat the same moves but since Zoro missed his Dragon Blaze attack, it gives him a reason to use it again.

What kind of dumbass believes that Sanji, Zoro, and the scabbards will go back there?
Stop with the Orochi vs Zoro thing...it's getting cringy.
Zoro will either fight King or Kaido.
