Success

He suddenly came to the realization that it was very difficult to complete the Heavenly Refinement for Heavy Silver. The quality of its material had been compromised during the lightning calamity. Despite completing the soul forging, there was no improvement. No wonder his uncle master used spirit alloys made from two types of metals for the four-element Heavenly Refinement. He had considered the metal's durability based on his experience!

Zhen Hua had explained many things to Tang Wulin but there were some areas that he could not quite understand. Explanations could never rival the hands-on experience of the process. 

Tang Wulin had already figured out many of the principles behind the Heavenly Refinement process. 

Had it not been for the Thunderclap Nether Vine's presence, Tang Wulin could not protect the three metal pieces. The lightning's destructive force was terrifying beyond comparison. Tang Wulin's body could not sustain the elemental calamity.
