Trick
Liu Yang was showing a solemn face when he heard the system voice, he doesn't know if his trick will work or not. He had to be very careful.
The women looked at the scene in a tense way, they realized that Liu Yang and the shadow were about to do something to decide the winner.
Looking at Liu Yang's face, the women realized that he was doing something very complicated. Only Sara understands what is going on and how much pressure Liu Yang is feeling for doing this.
Both hands slowly open the instant the voice echoes.
Liu Yang's hand opened slowly, but before it could be fully opened. The shadow hand was the first to open.
The shadow hand showed two fingers, this is the scissors symbol.
The instant Liu Yang saw this, he reacted quickly. He closed his hand again before he could open and form the symbol he wanted.
That is, Liu Yang showed stone while the shadow showed scissors.
