Xia Ling was startled. She did not expect that he would bring that up.
About half a year ago, when she was still a trainee, she once did a cover of "Sea Demon." At that time, she was urgently pressed by Imperial Entertainment to do so. To prove her capability, she spared no effort in singing and did not think that the video would be circulated so widely. Many of the vocal techniques she used in the song were exactly the same as those she used in her previous life. As such, she was worried that Feng Kun might have realized something.
Feng Kun said, "I personally made that song. I know how difficult it is to sing it. In fact, besides Xia Ling and you, no one else could sing it. There were too many whistle notes, and only very few people could sing them."
Whistle notes were also known as dolphin sounds.
It was true that in the whole world, only a few singers could control the whistle range well.
