-> Now with the full page , You can see Zoro lying on his torso with 0 stamina and struggling to even move with 30 bones broken ; Kaido got mad and ordered Law to stand back there and went on using his famous blitzing move Thunder Bagua and he hit Zoro and Law at the same time :
> As You can see Zoro was on lying his Torso but in that moment Kaido tried blitzing with a Bagua , he used his torso to get hit because of his ideology of getting hit on the back since it's a shame for swordmen .
So to get the point :
Zoro with 0 stamina turned over faster than Adv CoC Thunder Bagua so he wouldn't get hit in the back .
