Toying with you until death!

Sun Yaotian grit his teeth in hatred.

Who could he blame?

Blame Master Feng?

Master Feng hadn’t received a single cent from the Sun family. The moment he heard about Chen Yiran’s coming of age ceremony, he took the initiative to go himself. As for him appearing in such a fashion, it was something Master Feng agreed to after being begged multiple times. It was just that Sun Yaotian did not expect that ultimately Su Hao’s appearance at the end would destroy all his hard work. His action was like making a wedding dress for others!

And the worse part was what this piano origin ability technique used for?

To deal with psychological blows!
