Tang Haifeng wanted to stop them, because fighting wasn't a good thing, and he was worried that they could get hurt, but since both of them agreed, he couldn't do anything about it, so he just reminded them to be careful. "Do be careful!"
"I will!" Cao Wenxin gave her grandpa a perfunctory answer then ran to the yard, pulling Gu Ning followed by Tang Jiakai.
Tang Haifeng also followed them walking outside.
In the yard, Cao Wenxin and Gu Ning stood across from each other, while Tang Haifeng and Tang Jiakai stood three meters away.
Cao Wenxin asked, "Are you ready?"
"I'm ready," Gu Ning said.
"Great, let's begin!" Cao Wenxin said, and attacked Gu Ning at once. She wasn't sure about Gu Ning's strength, so she only used a third of her strength in case Gu Ning would be hurt. Facing Cao Wenxin, Gu Ning didn't bother to use much strength either.
