"You mean to say that Noble Consort Shu was murdered by someone?"
"I don't know really."
The old physician answered Xi Ying's question truthfully and then continued in a daze.
"Those guards wore Imperial guards' uniform so I thought that the Imperial Family members wanted to hide something by killing my master."
Xi Ying had now taken the dagger away from the old physician and leaned against the chair he was sitting on.
He actually didn't need any answer now because all of his questions seemed to be answered.
His eyes moved to Li Rui and he asked her softly.
"What do you think?"
Li Rui's face looked equally calm. However, her eyes were not that calm at this moment. Xi Ying could see that she had understood everything but she was unable to believe that what she was thinking was true.
However, he couldn't really blame her.
