The Battle of the World was a tournament held between all kingdoms, where only the best of the best could participate. Normally, there were 100 people per kingdom. The only main rule was that only people over 20 could participate.
Kayden, at the time, was 18 years old and therefore did not expect the invitation, because if it was just strength, he would have already participated before. The event took place at the end of the year, more specifically there were 3 days for a mysterious test and another three for battles in which they could be singles, pairs, or trios. Every year was revealed only on the day of the battle.
"What are the rewards?" Kayden wouldn't fight for anything, he never sought glory or fame and it wouldn't be any different now.
