LUO JIN watched as that panther beastkin turned into light particles. That's the signal that the match was over. He was actually impressed of Winged Tassel's last move. Probably because Black Cat had more of an impression on him. So, he thought that the other would surely win. Because of that preconceive notion, the fact that Winged Tassel was the one who won left a much bigger impact.
Even more so for him. Because whoever won that fight would be his opponent tomorrow. Of course, he had to win this fight first.
He walked out of the 'bench area' once the duke announced Winged Tassel as the winner. Finally, it's his turn. He felt like mushrooms would start to grow on his back because of all the waiting he had to do.
