Marcus knew that it might be one of the agreements between the knight king and the firebird king.
As the firebird king guarding the floating island, she couldn't tell Marcus about this.
It was unfair to other inheritors, so Marcus nodded at the firebird king.
He was about to tell them what he knew about the inheritor.
This could be a reference for the firebird king.
"There is another inheritor behind us called Hades. Hades is full of dark aura."
"I don't know why the knight king chose such a person as the heir. Later I had a guess."
Marcus told the firebird king about his guess. After he finished, the firebird king nodded.
"You're right. It's not that the knight king chose a person with a dark aura as his successor."
"But there was a part of the dark aura on the knight king, and then he gave it up."
The firebird king sighed and made her judgment.
"Now this part of the dark aura is the negative aura of the knight king."
