The cells in her body suddenly became active and the muscles all over her body exerted strength quietly. All the force was gathered on her fist. There was a smile at the corners of Yun Feng's eyes and she also swung her hand fiercely at the roof of the hall!
"Crack! Crack!" Tiny sounds came from the top of the hall under Yun Feng's heavy punch. Fine cracks immediately appeared and covered the top of the hall. Yun Feng narrowed her black eyes slightly as the heavy punch in her hand smashed down fiercely again!
The cracks became more and more obvious as Yun Feng exerted her strength. They extended from the top of the hall to the entire wall. Yun Feng laughed and swung her fist fiercely again. A crisp sound came from the center of the top of the hall and then collapsed!
Under the heavy punch, the roof of the hall was shattered just like that!
