"Hmm?"
As Yun Xiao was about to utilize some methods from his past life to help Yun Wei have a greater chance of activating her Ancestor Vein, he realized, after all, that he had thought too much.
Because at this moment, Yun Wei did not need Yun Xiao's help at all. On her right arm, identical to his, an extremely strange aura had emerged, an aura so potent that it even pushed Yun Xiao back a step.
At the same time, an intense cold burst forth from Yun Wei's right arm, and following that, Yun Xiao saw his sister's right-arm sleeve being frozen at a visibly rapid pace, appearing incredibly mystical.
"This… This is actually an Extreme Cold Attribute Ancestor Vein!"
When Yun Xiao witnessed this scene, a storm of shock surged within him. It wasn't that he was astonished at Yun Wei's activation of an Ancestor Vein – after all, being siblings of the same parents, the likelihood of Yun Wei activating an Ancestor Vein was also considerably high.
