Nux moved, dodging the incoming golden spears one by one. His movements were by no means graceful or effortless; in fact, one could see how much he had to focus just to avoid getting attacked. Actually, the only reason he was even able to manage and dodge all the spears was because his body was ridiculously fast.
Even if he moved at the very last instant, his body helped him fill in the gaps and dodge the spear successfully.
But since every single one of his movements was so extreme, every time he moved, he lost some sense of balance.
However, this didn't stop him. If anything, it only pushed him even further. He forced his body to regain his balance and continued. His rough movements began to improve at a ridiculous pace, as if he had done the same thing hundreds of thousands of times. His rhythm and body coordination continued to improve.
He was learning—adapting—in real time.
