The human king and all the commanders also get very interested the moment they get to know that Sam agrees to fight with Prince. Everyone is really interested to know what is the gap between the prince and Sam.
As you know both of them were in Epic grade, but still if you asked anybody they would tell Sam definitely won this fight. Because of this, all the high officials of the human Kingdom were really interested in that fight.
Fortunately Sam did not immediately agree to fight with the prince as he needed to recover The Spiritual energy. These also give everyone the time to prepare themselves and also finish their work before going to the training ground. As everyone is pretty busy because of the competition, they previously did not get that much time to do their work.
