Liu Die's speculation was actually quite bold.
After all, she still had the mindset of a salaried worker, thinking that it was very generous for a boss to give an employee who contributed intellectual effort a ten percent share in the company. In many large enterprises, the so-called stock incentives for dozens of executives amounted to merely a symbolic one percent of the shares combined.
According to Liu Die's estimation, Su Wen's ten percent share probably came with many restrictions, possibly requiring Su Wen to provide more drug formulas or the like. She couldn't believe that Su Wen was actually the one taking the initiative in this collaboration.
However, it wasn't that Liu Die lacked intelligence, but purely that she was unaware of the connection between Su Wen and He Shiguang behind the scenes. If Liu Die had known that He Shiguang's teacher had nearly become Su Wen's disciple, her guesses would certainly have been more accurate.
