Zoro really does care a lot about his swords. He willingly jumped to take free hits from King just to grab Sandai and Wado.
Full summary makes it clear that Zoro constantly had to manage his haki to prevent Enma from pulling.
This chapter is where Zoro uses the opposite technique by overloading Enma and passing the test. Since it was the fear of having his haki completely drained which was holding Zoro back.
Absolutely perfect chapter
