Chapter 873: Chapter 889-monarch or not, subject or not subject

Xiao Jiuyuan raised his eyebrows and said coldly,""This Prince already knows who poisoned this Prince."

Aunt SU's son quickly said,""Your Highness, it wasn't my mother's idea. Someone instructed my mother to do this. That person used me to threaten my mother. When my mother was a Palace maid in the past, she had a lover. Later, she got pregnant with me and secretly gave birth to me."

"That person used my life to threaten my mother, so my mother poisoned His Highness."

Xiao Jiuyuan nodded and said slowly,""The person who instructed your mother to poison me should be the Emperor, right?"

Aunt SU's son was surprised.""Your Highness understands."

"Yes, I wanted to ask you who instructed you to tell me this."

If no one had given him instructions, why would aunt SU's son talk to him about this?

Logically, he should not be looking for him.
