"Master!"
Duan Shu smiled, observing her disciple's stunned reaction.
"What's the matter, Yin Yun? You look like you've seen a ghost!" Yin Yun's eyes widened as she tried to find the words to express her astonishment.
"Master, you just surprised me; you shouldn't do that!" She finally managed to say it, her voice filled with a mix of shock and amusement.
Duan Shu chuckled. "Tell that to the foolish girl I have been calling for the past minute, who wasn't even paying attention to her surroundings." Duan Shu raised an eyebrow playfully, teasing Yin Yun.
Yin Yun's cheeks flushed with embarrassment as she realized that she had been lost in her own thoughts and hadn't heard her master calling.
"Sorry, Master, I was lost in my thoughts and didn't hear you calling. It won't happen again," Yin Yun apologized, her embarrassment evident in her voice.
