Qu Lanyi waited outside quietly. He had enough confidence about Yun Feng's potion this time. After a while, the door was opened and Yun Feng walked out with a bottle of potion in her hand. She waved it at Qu Lanyi. Qu Lanyi stood up and wiped the sweat on Yun Feng's forehead without saying anything. Light elements slowly seeped into her body. Qu Lanyi suddenly frowned after checking Yun Feng's body. "You consumed so much mental strength?"
Yun Feng chuckled. She sat on the chair a bit tiredly and looked at the bottle of potion in her hand. "Every time I make medicine, I have to fuse the elements. It's natural that my mental strength is consumed. As expected of a high-level three-star medicine. My mental strength is consumed more than I thought."
"So, the higher the level of the potion, the more mental strength it consumes for you?"
Yun Feng nodded. "Indeed, but the consumption is still within my tolerance. It's not a big deal."
