This is the exchange between Kunlun and Shen Wei, the first time they meet. (chapter 77, so mildly spoilerish. The more spoilery part, I hid under a cut.)
“You can’t speak? Impossible.” Kunlun Jun drapes shapelessly onto the large boulder, lifting a brow. “Got a name? What are you called?”
“… Wei.”
“Which Wei?”
“…Mountain ghost.”
“Mountain ghost?” Kunlun Jun stretches out over the boulder, lifting a brow, “Appropriate, but a bit weak. Look at this world: mountains and oceans joining one to the next, towering peaks linking in an unending chain. Why not add a few more strokes, make a Wei.”
[TN. 嵬, what the ghost king introduced himself as, means “rocky terrain.” 嵬 is written with the radical ‘mountain’ on top of ‘ghost’. 巍 means ‘towering’ and keeps both of the radicals of 嵬]
