Magic Tool, High Grade, Rank One.
Ou Yangming was slightly shocked when he saw the equivalent rank. Although he had smithed plenty of magic tools before this, the best magic tools that he made were only at the peak of Good Grade.
A High Grade magic tool was another huge threshold. Before Ou Yangming obtained better secret smithing techniques, he could not have anyhow smithed one.
Nonetheless, he unexpectedly smithed such a piece of equipment at this moment.
When Ou Yangming scanned the waist sash, he knew very well that this was not because his smithing art had improved. Instead, it was because the material used was too fine, hence the equipment's equivalent rank was forced to a higher level—High Grade.
It made sense because after all, how many people in this world could obtain a Wutong Tree's branch and successfully smith a piece of equipment with it?
Perhaps a High Grade magic tool was even the material's lower limit.
