Apart from the change in Race, Jiang Fei's Profession had also changed from Advanced Divine Blacksmith to Beginner God of Crafts. Although it might appear to be a demotion from Advanced to Beginner, Jiang Fei had only just become Ou Yezi's successor.
After the change in Profession, Jiang Fei lost all of his Profession related skills as a Divine Blacksmith, including Rose Cutter and Instant Ice Burst. Most of the production interfaces he previously owned had disappeared completely. They were all replaced by a new production interface with three God of Crafts' skills.
The new production interface allowed Jiang Fei to overcome the limitations of using Smelting equipment and the likes. He could now craft equipment whenever and wherever he wished without needing to return to the blacksmith's shop.
