Bo Xiu led the way.
They passed through a belt of icebergs, then crossed a vast, frozen plain.

"Bo Xiu! Where is the Lord? Is the Lord..."
"Bo Xiang pays his respects to the Lord!"
"Bo Ai pays her respects to the Lord!"
The two approaching figures saw Gu Zheng following behind Bo Xiu and immediately stopped, overcome with excitement as they performed a deep, respectful bow.
"...A pleasure to meet you both." Gu Zheng clasped his hands in a fist-and-palm salute.
"We are not worthy, we are not worthy." Bo Xiang, who was covered in corded muscle and had a rugged face, quickly sidestepped the gesture.
Bo Ai was a woman with a delicate appearance and bright eyes. She bowed deeply and said, "This way, my Lord. The Clan Leader is already waiting in the cave."
