The king in the wonderful kingdom of mathematics mainly has an indomitable trait, because the story inside is that when the monster army is attacking and then has killed many soldiers, some related soldiers tell the king to retreat quickly, but the king refuses to retreat, that is to say, even if there is only one person left, he will fight to the death with the monster army.

Therefore, such a plot can reflect the resilience of the king and some related spirits. Moreover, the king inside trusted the hero very much, that is to say, when the hero said that he would help him arrange his troops, he also readily agreed.

Then finally defeated the monster army, so the king inside has two characteristics, one is very unyielding and the other is very trusting.
