Who could blame Felix for feeling like this?
An open challenge for three days implied that he wouldn't be given much time to rest between his battles.
"Although it's called an open challenge, not everyone can apply to fight you." Anastasia clarified, "We have already chosen the best thirty contestants from four clans, who are slightly short from being picked in any of the teams."
"Is there going to be a time limit for each battle?" Felix asked.
"Naturally, we want everyone to have a fair chance."
Anastasia might have worded it like this, but Felix understood that this rule was implemented to avoid the fights dragging out for too long.
It would be for the benefits of Felix since he would have fewer challengers to fight against.
"I see...What was the reaction of the royal dragons when they heard about me?"
