Shen Mu was taken aback and asked, "What did you say?"
Huo Yunxiao glanced at the room that had already been deciphered and asked again, "Have you learned Morse code?"
Shen Mu opened her mouth to speak, but before she could say anything, Huo Yunxiao said, "Don't lie to me."
After hesitating for a moment, Shen Mu nodded and said, "I have learned it."
Huo Yunxiao frowned and asked, "Who did you learn it from?"
Shen Mu didn't say anything, and Huo Yunxiao asked again, "Can't say?"
Shen Mu nodded, and with very little confidence, she made a sound of "Mm".
Huo Yunxiao's eyes darkened and he asked, "What about the Spanish code for the next level, have you learned Spanish?"
Shen Mu made another sound of "Mm" with even less confidence and said, "I have learned a little."
Huo Yunxiao asked again, "Still can't say?"
This time, Shen Mu had no confidence left and just looked elsewhere with guilt.
