Cai Wei asked with a hint of curiosity, "There's something I've always wondered about. Tianjizi was in cahoots with Jin Guifei and her son, so why didn't he kill you? Logically, with his mana, it should have been as easy as flipping his hand to kill you, right?"
When the past was brought up, a serious look crossed the man's face as he said, "Tianjizi's mana was mighty and unfathomable. To gain his support, Duke Li Guo's Mansion spared no effort in courting him. The reason he didn't kill me was, firstly, because my maternal grandfather had invested a lot of silver and thought into him, and secondly, because it was better to control Nangong Shi by keeping me alive. If Nangong Shi dared to disobey even a little, Tianjizi would abandon him and support me instead!"
"What a cunning old demon!"
Cai Wei said indignantly, "Thank goodness he's dead, or the one sitting here wouldn't be you!"
