Within 10 seconds, a handprint clearly showed up on Gu Yusheng's face.
As he was taller than his grandfather, Gu Yusheng had to slightly lower his head to look at him directly. They stared at each other for a long time; neither of them wanted to back off. Finally, Gu Yusheng moved his lips and said in a low voice, "Is that enough?"
Old Master Gu did not answer, and in the next moment Gu Yusheng grabbed his grandfather's hand and used it to slap himself again like he had before.
This time, Gu Yusheng did not even bother to ask if that was enough. He stared at his grandfather for a few seconds and, realizing he was still going to remain silent, grabbed his grandfather's hand for the third time to slap himself.
Just as Old Master Gu's hand was about to touch Gu Yusheng's face, he finally realized what was happening and forcefully pulled his hand back so Gu Yusheng would stop slapping himself. "Gu Yusheng, what are you doing?"
