Young Master Long of the Dragon Sword Manor chose to step onto the arena on the final day because he was confident of winning. He wanted to let his potential competitors know that they should take advantage of their last chance to qualify - because that final spot was his!
Of course, Young Master Long did possess the strength to back up his confidence. His swordsmanship from the Dragon Sword Manor and the Dragon Mind Skill allowed him to look down on others with pride.
As expected, many people didn't dare to challenge Young Master Long when they learned that he was going to compete on the final day. They had rushed to secure their places before then. During the last three days, only a handful of people dared to fight for the final spot, either because they came late or just learned the news. Without exception, they all fell to Young Master Long, who effortlessly secured his victories.
