Like Ai Xing, Aier was a member of the Dragon Tamer Family, and she seemed to be his older cousin. Back then, feeling that she was not strong enough, she had left Chu Xin of her own accord and gone to Dragon Tamer Island for its trials, hoping to improve her strength through the Dragon Tamer Trial.
However, Aier had underestimated the trials on Dragon Tamer Island and ended up trapped inside. In the end, Aixin had taken Chu Xin to Dragon Tamer Island and given Aier Garchomp's Mega Evolution Stone, helping her complete the trial.
But when he had gone there, Sister Aier had apparently only made it through the second trial. Back then, Aier had not even been strong enough to clear the second level on her own. She had only passed because Ai Xing had brought Chu Xin to help her out. He wondered how strong Sister Aier was now.
"Sister Aier, how many levels of the trial have you cleared?"
"Me? I've cleared four."
Four levels! The Dragon Valley trial on Dragon Tamer Island only had five levels in total. Each level had ten stages, with the difficulty increasing at every stage.
Chu Xin had needed to give it his all just to clear the first level. Even after training for so long, he still could not guarantee that he could pass the second. To think that Aier, who had once struggled so much with the second level, had now cleared four!
"Wow, Sister Aier, you've gotten so strong! You've already cleared four levels! By the way, what's the fifth level like?"
Chu Xin had experienced the Dragon Valley trial himself. He had needed to use all his strength on the first level alone; he had not even dared to think about the second or third.
