Ye Lan looked towards the desk beside her.
Although she had been exploding the furnace all this time, she was well aware of how many medicinal ingredients had been prepared and how many she herself had used.
And now, apart from what she had used, there was only one portion of the ingredients missing.
This indicated that Shen Yi had picked up the thin booklet, casually flipped through a few alchemy formulas, and had managed to produce such flawless elixirs on his first attempt.
This was not something that could be achieved with just a superficial understanding.
The elixir for a Seventh-Grade True Immortal was not considered high-grade at Fifth Peak, otherwise, it would not have been recorded in the entry-level section.
The problem was, Shen Yi was not a disciple of Dan Peak, he had not studied the precious legacies left by the masters, and thus should not be evaluated by the standards here.
