After Jiang Yu went on stage, she first bowed to the audience and then sat in front of the piano. She took a deep breath and her ten fingers danced nimbly on the black and white keys of the piano.
Jiang Yu played John Strauss Jr.'s "Blue Danube River", which was known as the "Second national anthem of Austria".
Professor Carl closed his eyes and listened to the song quietly. His previous frustration had now been calmed down.
When the song came to an end, there was complete silence below the stage.
Professor Karl slowly opened his eyes and could not help but applaud Jiang Yu.
"Professor Bai, your disciple's strength is indeed not bad. I think highly of her," said Professor Karl.
Professor Bai smiled and said, "Jiang Yu is indeed my proudest disciple."
Professor Karl clapped his hands in approval and said, "Good! Then Jiang Yu will be the fifth person I choose!"
