Chu Qianli pretended to return to the Prince Residence.
In fact, that very night, she took advantage of the power of the Heavenly Silkworm Silk to float gently down onto the rooftops of the Prince Residence.
Although the courtyard of Chu Buqu was heavily guarded, the Duke Residence's real expert was only Han Zhan.
Compared to the Prince Residence, teeming with hidden dragons and crouching tigers, its guards were hardly a challenge for Chu Qianli.
So, when Han Zhan was not in this courtyard, it was much too easy for Chu Qianli to enter.
Inside the room, there was only one servant whom Chu Qianli did not recognize on watch, not even a doctor.
Isn't the illness very serious? Why isn't there a doctor attending at all times?
Chu Qianli had felt something was off early on.
She took advantage of the night to sneak in, and indeed, the timing was right.
She pinched a silver needle in her hand and flicked it lightly.
