Fang Yuan had a sudden inspiration, he thought of a great method.
The Gu recipe was given, but Gu Masters could refine the Gu using their own techniques. For example, to fuse two materials, they can use fire to melt them into one, but they could also use water to fuse them together as another method.
Two different methods would be able to achieve the same results.
Thirty minutes later, Fang Yuan's name was on the first place spot, and he obtained green shine Gu.
Fang Yuan did not practice this water-fire refinement method much, but the difficulty of refining water light Gu was too low, even with his rusty technique, he refined two hundred and seventy-seven. He was one Gu above the criteria for first place.
