A Spiritual Treasure of Chaos at the Highest Grade was not a usual Magic Weapon. Even only two of the five Cultivators at the Peak of the Fate Realm had one. Therefore, when Minghe suddenly took out one, he had to attract the others' attention. They even intended to give up on the Fruits of Stars of the Origin, and instead, planned to steal that Highest Grade Spiritual Treasure of Chaos.
However, they tried to control their impulsions. They knew that a Highest Grade Spiritual Treasure of Chaos was precious, but not everyone could own one. Otherwise, the three of them could also have one. In addition to having a profound background, one needed to refine one by himself or meet with some Fated Chance so that he could own one.
