Instead of answering his question, Joshua asked, "What is our probability of winning the duel?"
"Ninety nine percent." Xander said confidently. "Unless miracle happens, it's impossible for them to win."
Then, Xander explained why victory was almost guaranteed.
He said they could propose Battle Royale or Three-way knockout format. They could first focus on eliminating the Nightshire City group before facing on each other.
Once the Nightshire City group was eliminated, it didn't matter who would be the winner among them because they were on the same side.
"What if she refuses the idea?" Joshua inquired.
"We can threaten her by saying we will attack her city together." Xander answered, "I'm sure she will agree immediately because solving the problem with a duel was better than going to war."
He then continued, "As for our participants, let's hire someone powerful and change their appearance with magic. With this, our victory will be guaranteed."
