Han Fei and the other refiners looked at each other in bewilderment.
In the end, it was Yu Xu who said unhurriedly, "There's no need to repeat. Those who can follow already understand, those who can't follow won't understand no matter how many times he repeats himself. Han Fei's plan involves a lot of knowledge of arrays. Those who don't have enough knowledge can hardly comprehend a combination of three hundred arrays."
Li Feiyun nodded. "That's true. However, Han Fei, there are a few problems regarding your plan."
Han Fei grinned and continued immediately, "Do tell me, Senior."
Li Feiyun said, "In the phase of Spirit Polishing, I don't think using the absorption of these few arrays is enough to gather the essence of materials."
Han Fei nodded. "That's the key to Spirit Polishing. My current arrays aren't enough to solve the problem, but I'm sure someone can."
