After entering the room, Feng Yun didn't waste time, and directly took out the Nirvana Flame Cauldron and the refining materials. After that, he began refining.
Feng Yun's main mission to become a fourth-ranked weapon refining. The third level of weapon refiners could refine Mid-Grade Earth Ranked weapons, but the fourth level refiner could refine Top Grade Earth Ranked weapons.
Feng Yun was still far away from refining the Top Grade Earth Ranked weapons, he couldn't even refine High-Grade Earth Ranked Weapons.
[First Level/ranked refiner - Low Grade, Mid-Grade Spirit Ranked weapon.]
[Second Level refiner - High Grade, Top-Grade Spirit Ranked weapon.]
[Third Level refiner - Low Grade, Mid-Grade Earth Ranked weapon.]
[Fourth Level refiner - High Grade, Top Grade Earth Ranked weapon.]
[Fifth Level refiner - Low Grade, Mid Grade Sky Ranked weapon.]
[Sixth Level refiner - High Grade, Top Grade Sky Ranked weapon.]
So on...
