"People from the pharmaceutical factory?" Zhuang Shengxian shook his head, "They've been with me for over twenty years; it's impossible for them to betray me just like that. Besides, I gave them the formula in parts."
Zhuo Yufeng nodded: "For the formula to be leaked, it must have involved several people colluding. It's unlikely for them to betray us all at the same time."
Bei Ran looked at him: "Have you ever brought the pharmaceutical formula back home? Or taken it to some other place?"
"I often bring it home to study. Sometimes, I wake up in the middle of the night with sudden inspiration..." Upon seeing Bei Ran, Zhuang Shengxian, though he had lost the pharmaceutical prescription, still felt joy inside.
Bei Ran and Zhuo Yufeng exchanged glances, and she said, "We're without a clue now. Director Zhuang, do you have any of my mother's belongings? May I have a look?"
"Of course you can!" Zhuang Shengxian said, "You're welcome to look anytime you wish!"
