"You bastard!" Old Master Gu picked up his crutch and smashed it on Gu Sheng's back.
Gu Sheng howled and curled up to the corner to hide, but Gu Hai didn't show mercy, still hitting him with the crutch.
Yan Xi stood at the side, feeling very happy. She curled her lips and her eyes were cold. When she felt that it was about time, she went forward to stop Old Master Gu.
"Grandfather, it's enough," she cried. "Don't be angry and risk your health."
Old Master Gu was in a fit of anger, so he couldn't care less about Yan Xi. He shook her off and kicked Gu Sheng hard.
Yan Xi was caught off guard and fell to the ground, gasping in pain.
Only then did Old Master Gu stop. He supported and asked with concern, "Are you hurt? Do you need to see a doctor?"
