Gu Lan lowered her eyes, not telling You Ying that this was indeed a wild guess of her own.
However, she probably guessed it right.
"Now I suspect that the reason the former Emperor suddenly drafted an edict to depose the Crown Prince back then was because he discovered something. Since Consort Jia could unintentionally discover the edict to depose the Crown Prince, the likelihood of Empress Dowager Su knowing is naturally greater. Perhaps Rong Jing and Empress Dowager Su acted first, leading to the former Emperor's sudden severe illness and death, and Zhang Ruoshui being publicly executed by Zhang Fengcai...
In any case, continue your investigation. Didn't Su Wenzhong retire to his hometown? Send someone to find him there. Since he warned Xie Yun before, he must know something. But handle this matter cautiously, don't alert the enemy."
You Ying nodded, "Understood, I will contact Lin He and have the Inner Supervision step in to gain Su Wenzhong's trust."
