The muscles and bones in his neck were instantly infused with a mysterious power, becoming more resilient and flexible. Looking inward, he saw that the tissue structure hadn't changed at all; its function had simply been expanded.
The entire transformation took less than three minutes. The stronger Yu Fei became, the greater his body's tolerance for new abilities.
Yu Fei let out a long sigh of relief. He had previously researched the principles behind how an owl—that assassin of the night—could rotate its head and discovered that its skeletal structure was completely different from a normal creature's. He had been worried that installing the ability would make his own neck bizarre.
If a real structural change had occurred, Yu Fei had planned to just break down the ability; he figured he would be able to return to normal that way.
Having taken the risk just now, he realized he had been overthinking things. His neck was still his neck; its function had merely been extended.
