"Hmm." Si Fan said in a low voice, "If you want to gain her trust, you have to do something that she thinks I spy would never do. That'll work. Hmph, looks like I've underestimated her. I thought she wouldn't be this cautious. It turns out that she still has some brains."
"Then what should we do?" Cheng She hurriedly asked.
Si Fan sneered and said, "Just as I expected. You're my assistant and have been with me for so long. It's normal for Yin Xun to suspect you. If she didn't, I'd be worried that she has something up her sleeve. How about this? Tell her that Dong Zi is an undercover agent and say that you overheard this news. If she doesn't believe me, make her search Dong Zi's pockets. I placed a note in Dong Zi's bag."
Cheng She said, "Are we going to sell out Dong Zi just like that?"
Having been by Si Fan's side for so long, he used to think that Si Fan was quite cruel. Now, it seemed that Si Fan had no conscience at all.
