Failed?
The round became one of horrors, at least for the others. Surprisingly, Ryu began a series of continuous challenges that made others afraid to even move forward. It turned out that the rule that you couldn't challenge twice in a row was nothing more than a facade. The reason Ryu had failed to challenge twice in a row in the past was because Litaor was foolish enough to get punished even before the challenge even began.
The real rule was simple. So long as you succeeded in your duel and the challenge that followed it, you could continue to challenge others.
And so, Ryu continued to do so until he realized that it was well and truly not worth it, at least not for now. What was the point in challenging others when they had hardly moved forward. His pillar was bouncing back and forth to the left and right rather than actually moving forward. The only benefit really was the Heavenly Favor, but his own was so large that it hardly made a dent.
