Ignoring the stunned five-member team outside due to the energy fluctuation caused by Yun Xiao's breakthrough, Yun Xiao himself was already experiencing another surprise in the room.
The breakthrough to the Meridian Gathering Realm was complete. As Yun Xiao opened his eyes and sensed the meridian Qi strength, which was several times stronger, a peculiar aura suddenly emerged from his left shoulder.
Crack! Crack!
A distinct sound reached Yun Xiao's ears, and when he lowered his gaze to his left, he saw layers of frost forming on his left shoulder and creeping towards his left arm, heading straight for his palm.
"This... this is..."
Seeing this scene, Yun Xiao first paused in slight astonishment, then his face erupted with ecstasy as he couldn't help but exclaim aloud: "It's actually a second Ancestor Vein, and it is the Water Extreme of the Ice Attribute Ancestor Vein!"
