"Sure. I have four left. Each costs nine hundred and thirty million." Lu Feng answered.

Mu Feng's jaw dropped. "That's a rip off!" he complained.

Mu Feng couldn't lose such an opportunity to give away these potions. They were too precious. "Fine, prepare them tomorrow." He said grumpily.

Mu Lan heard their conversation while she was hiding her face. She blinked. 'How did he know that Dr Lu Feng made such an exclusive potion? Did he see all of it himself just like us? Then was he the one who closed the door?'

Lu Feng asked the same question what she wanted to ask, "How do you know what I created? Did you just see what happened in the bedroom?"
