Sun Yuzhi crept to the door of Chen Sheng's room and knocked softly. She waited for his reply before pushing the door open and stepping inside.
With a look of worry and urgency on her face, she immediately asked about what Chen Sheng had mentioned during the day—the matter of investigating the whereabouts of the Phoenix Yin Gu King.
Earlier, in the Poison Flame Cave, Chen Sheng had speculated that the Phoenix Yin Gu King's disappearance might be related to the Ten Thousand Poisons Sect.
After his analysis, a seed of doubt had been planted in Sun Yuzhi's heart.
Afterward, Chen Sheng had said he would find a way to subtly probe Lady Lan for information, so she had temporarily set the matter aside.
However, after mulling it over for a long time by herself, Sun Yuzhi felt increasingly that this plan might not be sound.
