In the middle of the battle ring, Kahn intentionally revealed the information about his sword being made by Albestros Winston, one of the peak grandmaster blacksmiths of the Rakos Empire.
There was a reason for him to reveal this hand this early. Because today's experience already made him realize that nobody paid attention to an underdog and they're easy to remove if people aren't watching.
So before the result of this match came out, he'd at least use this opportunity to reveal the man who was backing him up.
He only revealed that his sword was made by Albestros to the audience but soon, the news would reach the top brass and then will take notice of him because of the rumors he already spread last week.
So the majority of the so-called clans and their people will be hesitant about picking a fight with him as they do with people without any powerful background.
