Paternity testing was not something that could be done when he wished!
Even if he insisted, the old man would surely disagree.
This was because amniotic fluid puncture could only be performed under the right condition. There would be a danger of miscarriage if it was performed too early into the pregnancy.
It was usually performed after the first trimester.
As the continuation of this family's bloodline was very important to the old man, he would naturally disagree to this test.
With him around, she would be safe for the next two months at least. This meant that she would have a window of two months to strategize.
Two months later, she would have her way to have a 'natural miscarriage'.
As long as she moved swifter than Mu Yazhe, he would have no way to prove that the child was not his.
If everything went according to plan, all her worries would be resolved.
