Yu Jung-ak's movements in slow motion were astonishing. Yu Jung-ak knew that Aoki would use his hands first to succeed faster when performing a heel hook. Sure enough, Aoki was reaching out with his hands before even wrapping his legs. As soon as Aoki grabbed his leg, Yu Jung-ak leaped up powerfully. Yu Jung-ak's large body spun magnificently through the air once before landing.
It was a move known as a back flip or backward somersault. In short, as soon as Aoki grabbed his foot, Yu Jung-ak flipped backward once. Because he spun using the strength of his free foot, Aoki couldn't hold on with just the strength of his hands.
If the leg lock had been perfectly set, Yu Jung-ak's body wouldn't have been able to spin properly and would have fallen to the ground. However, because the lock wasn't properly set, Yu Jung-ak was able to easily escape Aoki's technique.
