Yu Youyao suddenly understood. "The Empress Dowager is seriously ill, and the Empress is weak. Yu Zongshen and Ding You are at home, and the royalists are at their weakest. Concubine Lan and Imperial Concubine Xu are going to take advantage of the situation to attack the royalists."

Concubine Lan and Imperial Concubine Xu naturally wouldn't watch helplessly as the Empress grew.
