Bai Ruozhu couldn't help remembering the time when she tried to bribe Jiang Yichun to break Sanlang's leg. Jiang Yichun took off his mask to prove his identity. He also took off his mask when he met her privately, and didn't wear a mask at all at night. It turned out that the mask wasn't unique to him.
However, on further reflection, the mask on the man's face just now was slightly different from Jiang Yichun's. Only up close could she discern this. His physique was also similar to Jiang Yichun's. Upon closer examination, though, she was able to detect differences in their demeanor. It was just that she was too overjoyed just now, and didn't observe him carefully.
Perhaps all the members of the confidential department of the Tongzhi Division wear such masks. The man just now must have been from the Tongzhi Division as well.
Bai Ruozhu embarrassedly gave her second brother a wry smile, having never expected to recognize the wrong person.
