Chu Yi paid no further attention to Fei Zhengyang and Wei Zhiming; he poured all of his focus into artifact refining.
Spiritual sense began to gather bit by bit as Chu Yi used it to guide the earth fire, carefully inducing it through various patterns of the edge materials, modulating the intensity of the flame.
There were already more than a dozen strands of earth fire, and now, to see someone able to vary each flame's size was something that, until this moment, neither Fei Zhengyang nor Wei Zhiming had ever witnessed.
As the flames gradually grew larger and then smaller, the materials at the edges of the copper furnace began to undergo various changes.
Then, Chu Yi once again drove his spiritual sense to gradually push these changing materials toward the center of the copper furnace.
The center of the copper furnace had now turned fiery red.
As these materials entered it, Chu Yi consolidated all the earth fire into a single, large bundle.
