After watching for a while, Lu Heng confirmed that this was a master-level Quenching Master.
"Wind Spirit Crystal." The master-level Quenching Master said the name of a material, and his Quenching Assistant hurriedly searched for the Wind Spirit Crystal in the pile of materials.
However, the Quenching Assistant seemed not very skilled, taking a long time without finding it.
The master-level Quenching Master was clearly displeased, and his breathing grew heavier.
Lu Heng glanced at the materials on the table, spotted the Wind Spirit Crystal wrapped in a layer of stone dust, and realized it was not easily recognizable.
Seeing the Quenching Assistant searching elsewhere,
Lu Heng simply walked over, picked up the Wind Spirit Crystal, and passed it on.
The master-level Quenching Master turned to look at Lu Heng, then threw the Wind Spirit Crystal into the Quenching Furnace and continued with the process.
