Never mind how fast Su Han's refining speed is or how high his success rate is, what puzzled Ling Qinghai the most was where Su Han got so much gold coin from?
According to his investigations, Su Han truly was just a junior member of the Su Family from Yuanshan County, who had once suffered a disruption in his Dragon Vein due to cultivation deviating into madness. Somehow he had recovered later on, but after provoking the Chen Family and the Lin Family, he was expelled from the Su Family and had been living under the care of the Xiao Family ever since.
The items required for this sect mission, when added up, were valued close to one billion. It's not just the Su Family or the Xiao Family that couldn't afford this sum—even if all four of the Four Great Families of Yuanshan County were to pool their resources together, they still couldn't come up with the amount!
"Indeed, the professions of artifact refiners and alchemists are truly lucrative to the extreme," Ling Qinghai sighed.
