Rui raised an eyebrow as an amused smile sprouted on his face. He felt bad, but his first reaction was one where he had a hard time taking Kane seriously. He was so far ahead of him on a general level that the two were no longer operating on the same scale.
Furthermore, Rui grew stronger against opponents the more he knew about them, and he knew Kane really well. The predictive model he had on the guy was incredibly robust and sophisticated. It was better than any predictive model he had ever created in his life.
What that meant was that Kane did not stand a chance against him ordinarily. Rui was confident that he would be able to fight three, or even five Kanes under normal circumstances.
However, he quickly realized that his confidence wasn't entirely unwarranted. The new technique that Kane had developed allowed him to develop multiple techniques that allowed him to fight people much stronger than himself.
('No, it made him much stronger, period,') Rui corrected himself.
