Bei Gong Ao's expression changed. He forgot that Sima You Yue was an alchemist as well. He said with an embarrassed smile, "It's possible that there are people refining in the surrounding courtyards."
"That's true. All the branches in this alchemist clan can refine pills." Sima You Yue smiled as she walked past. She stopped questioning him, which allowed Bei Gong Ao to release a breath he had been holding.
When they reached the place that Sima You Yue had been staying in temporarily, Bei Gong Ao wanted to leave quickly. The statement that Sima You Yue had commented casually had caused his old face to perceive something. He had thought that she had realised something, but was just showing a nonchalant expression.
Sima You Yue watched Bei Gong Ao's retreating back and thought of the words he said just now. Hatred filled her heart, that was on the same level as the one she felt for Bei Gong Er.
