Between the fourth-grade high stage and the fourth-grade perfect, there was an inherent gap. In addition, Wei Gang held the Treasure Furnace in his hand, which multiplied the formation of elixirs and their quantity, far surpassing Feng Qian. Naturally, Feng Qian wouldn't have any chance of winning.
As for Yang Chen, his eyes could instantly appraise an alchemist's level. As long as he observed someone's alchemy techniques, he could immediately discern what kind of elixir they were refining. Moreover, that wasn't even his limit. He could even estimate the amount of elixirs someone could refine and the final quality of their elixirs.
This was why he quickly knew the outcome, because he had already appraised the results of Feng Qian's elixirs, along with Wei Gang's. After comparing the two, Feng Qian's results would only end in a miserable defeat.
The outcome was no different from what he had expected, there was no disparity at all.
