Su seemed to only be improving with every attack she blocked or used a shield to deflect. This battle was against a much tougher opponent now that the dragonkin was not taking her lightly. It had trained for a lot of time and was certainly better when it came to battle instinct. If that was all that decided the winner, then it would be an easy win for him.
Unfortunately, Su was not simply a human fighting him. She was a draconic guardian that had accepted the ritual and pledge their life to protect a dragon champion. The blood and the system had been connected from the start. It was not just some small symbolic gesture that someone would use to show status. It was a key to a draconic guardian truly awakening who they were.
