章 716: Chapter 716: we must be careful of her

Mu Siyin paused for a moment and nodded. “What is it? Tell me.”

President Wang was silent for a moment before he slowly said, “That’s right, the old madam helped find a source of filth...”

When Mu Siyin heard this, she raised her eyebrows slightly. Could it be... Mu Xingyu?

“Is that so? where... did she find it?”

President Wang not only trusted Mu Siyin now, but he was also grateful. Although old Madam Mu had found a source of filth, president Wang didn’t feel at ease using old madam mu to find it.

“Actually... it’s Mu Xingyu.”

The answer was within Mu Siyin’s expectations.

Mu Siyin truly felt that old Madam Mu’s heart was the most vicious one she had ever seen. Shi Beiyu couldn’t help but shake his head as he listened from the side.

This old Madam Mu was really obsessed with having a grandson. She actually did not let go of either of her two biological granddaughters.
