章 559: Chapter 559: The Jiang Family Needs Seventh Miss

Jiang Mubai casually picked up a stack of letter paper and handed it to him.

"I've seen it." Jiang Ruobai glanced at it and quickly looked away.

"Oh? It seems that this Seventh Sister is indeed clever." Jiang Mubai quickly realized that Jiang Ning had found out about Mu Jian almost at the same time as him.

That was quite rare.

Although Jiang Ning was in the palace and seemed more convenient, she was in a difficult situation now and could not move freely in and out of the East Palace. The only person she could rely on was Gucheng.

As for Gucheng, his martial arts skills were high and he was loyal, but his mind was not flexible enough.

He was good enough to be an Imperial Guard, but not quite enough to be an assistant.

Under such circumstances, she was still able to accurately and quickly find out the real culprit, proving that she was smart and resourceful.

Jiang Mubai couldn't help but feel both envious and jealous of his brother.
