The two people inside the room stopped talking.
They were worried, they were anxious!
They truly didn't believe that Cheng Zhihai, along with themselves, or rather, the entire Bureau of the Lamp, would be able to find the crown prince within such a short month.
Who was the crown prince?
He was someone who had contended with Emperor Zhou of Great Zhou for decades, who, even after being stripped of his qualifications to inherit the throne, could still hide in the shadows and secretly plot rebellion.
Such a person was too cunning!
Such a person was too ghostly!
He wasn't someone they could simply find.
In their hearts, they felt that this task was as difficult as ascending to the heavens.
Cheng Zhihai was surely going to leave the Bureau of the Lamp.
Thinking of this, Qian Siyuan and the person next to him felt their hearts turn gray, and their mood inevitably sank.
