George Bernard Dantzig was a mathematician, who was also known as the father of linear programming. One day, when he went to a class late, he saw two problems on the corner of the blackboard and mistook them as assignments. He copied them onto his notebook and solved them when he got back home. It was only later he found out that the problems he solved weren’t homework, but ones that his teacher had brought up as unsolved problems in statistics. Hearing this, he said his famous lines, ‘No wonder the problems seemed to be a little harder than usual’. 

This mathematician came to Chi-Woo’s mind when he heard Yeriel’s story. There was a high possibility that the sky-blue metal Yeriel was talking about was reliquia. Reliquia was a top-tier metal that a mere human wouldn’t dare try to manipulate with their abilities. That was why Chi-Woo had offered it to La Bella; he couldn’t do anything with it himself.

Then, when the two arrived at the workshop, Yeriel showed Chi-Woo a metallic ball the size of a fist. It was shaped like the AI Armor prototype that Yeriel had shown the other Seven Stars’ members. But instead...
