Constantine II seems to have inherited his parents' flaws: narrow-mindedness, arrogance, irritability, and a lack of cunning.
Therefore, basically, as long as a plot is made, he will fall for it.
Of course, such a chieftain can still hold a position in The Barbaric Wilderness, and can even do quite well. This kind of character is mainstream among the chieftains in the Southern Barbaric Lands, and a sly person like Constantine is the oddity.
So, previously, Constantine and Alfonso conspired to annihilate the Wild Horse Tribe, setting an extremely vile precedent in the Southern Barbaric Lands. Fortunately, Nini'an married the young Barbarian King as a concubine; otherwise, with the Chimera and Ankara Tribe so weak now, they would have been destroyed ten times over.
Upon hearing that his mine was occupied by Lanling and the iron and steel ingots inside were seized, Constantine II flew into a rage and immediately wanted to muster his troops for battle.
