Bai Ruozhu inspected around but found no signs of poison, evidently the other party hadn't tampered with the Guest Palace, or rather, hadn't infiltrated it at all.
"I know!" She slapped her head, realizing she had been thinking along the wrong lines.
The situation at that time was too sudden, her first thought was that there might be a Poison Master on site. However, many Poison Masters are proficient in poison but not good at martial arts, as most of their time is spent researching and creating poisons rather than focusing on martial arts or inner strength.
Thus, Poison Masters often hide in the shadows, like the one who infiltrated the Bai Residence earlier, adept at disguises and concealment, cautiously staying hidden.
And the Guest Palace, being the emperor's domain, is guarded openly by guards, and secretly by Shadow Guards, along with Yin Yang Masters, which makes it risky for a Poison Master to show up, fearing no return.
