Chapter 402: A Busy Zhang Yu
As Zhang Yu’s mastery of refining Azure Sand leveled up to Grade 2, countless scenes flashed through his mind—intricate sequences of refining Azure Sand, the precise flows of mana and martial qi, how to handle materials, timing the heat, the micro-details of spraying fiber-composite membranes, and stabilizing mana circuits…
One memory after another surfaced, giving Zhang Yu a deeper understanding and insight into Azure Sand refinement.
So when he attempted the process again using just one-tenth the usual materials, his success rate rose significantly.
Even the quality of the Azure Sand visibly improved.
Watching from the side, Ye Xingli raised her brows slightly in surprise at the refined product in Zhang Yu’s hands. “The color’s brighter, and it looks much purer than before… Is this Grade 2 Azure Sand?”
“Just lucky? Or is he actually progressing this fast?”
She kept observing but soon noticed Zhang Yu once again starting to compress the refinement time recklessly, causing the output to drop back to Grade 1.
By the end of their six-hour practice session, Zhang Yu had managed to reduce his refinement time to fifteen minutes through repeated attempts.
“Material usage reduced to one-tenth—that’s 0.003 spirit coins.”
