Ace and everyone had to wait until Doom finished his checking. He was very curious about what could make the lich so surprised like that. However, he didn't have to wait much longer. Doom then took out 5 translucent stones. Each of them didn't have the same shape, but they were the same size as each other.
"I believe they are the evolution stones," Doom then showed them to Ace and the others.
Ace then took one and checked it.
