Chapter 642: Another Genius

With the experience from last time's pill refinement, Ye Feng's work this time went much more smoothly.

After only half an hour, he had transformed all of the Marrow-Cleansing Pills from lower first-grade to upper first-grade.

Each Marrow-Cleansing Pill turned from light green to a rich purple, with an overwhelming medicinal fragrance.

After finishing all this, Ye Feng left three Marrow-Cleansing Pills and a note for Bai Wu, asking her to take care of the herbs in the medicinal fields and also reminding her to remember to take the remaining Marrow-Cleansing Pills with Su Xiaoqin and Liu Yiyi.

Then he hailed a taxi and rushed back to Tongren Medical University, called out Jiang Yuxin, and took her to the small grove behind the mountains.

"What is this? I won't just eat anything without an explanation..."

As Ye Feng took out the Marrow-Cleansing Pill, Jiang Yuxin stared at him warily.

"..."

Seeing the girl on guard as if he were a thief, Ye Feng was at a loss for words.
