"Grandma, Gu En already knew at the time that He Zhilan was actually Gu Zhilan. Lan Song had sent word; Gu En knew Lan Song had captured He Zhilan as a hostage. By then, Gu En should have realized that Lan Song planned to use Gu Zhilan as his final shield to trade for his own life. However, Gu En did not want He Zhilan's true identity to be exposed, so it's likely she instructed Luo Jinsheng to kill Lan Song immediately if he mentioned anything related to Gu Zhilan. This means it's probable Luo Jinsheng already knew that He Zhilan was Gu Zhilan at the time."
Lan Li's analysis instantly plunged everyone into silence.
It seemed almost as if the Gu En Lan Li spoke of was completely different from the one everyone knew—so terrifying.
