If Lang didn't have her wits intact within her, she would have rushed out and fought with the Zhu family but she didn't—— The Zhu family didn't deserve just a few punches and kicks they deserved something much more worse… didn't they almost killed her son because they wanted to pave the future for their kids? Then she will make sure that there was no future for the entire Zhu family!
Zhu Qian noticed that his wife's face wasn't looking good but he said nothing—— the Zhu family was his family and he was willing to suffer silently because they were his blood relatives but this suffering and biasness, if it would have been limited to him alone he would have said nothing but when it came to her son… there was no way he was going to stay silent.
What his family did to him, he was willing to suffer that injustice silently but not his kids.
