Liu Shitou said that when Yang Xiaolian was pregnant with their second child, she had also thought about killing Liu Shitou.
But she soon abandoned such thoughts.
No matter how bad or wanton Yang Xiaolian might be, in the end, she was still just a woman.
Moreover, Liu Shitou had always treated her very well.
Even though they lived in poverty, her food, clothing, and drink were still much better than those of the other daughters-in-law in the village.
In addition, having been found with another man by Liu Shitou, she was already sorry enough. Even if she was heartless, she certainly wouldn't want to kill Liu Shitou.
She just thought of running away with Liu Shitou's money and their second child.
So, when she saw that their second child wanted to kill Liu Shitou, she immediately took action to stop him.
Murder is a crime.
Even if hidden very carefully, there would definitely come a day when it is discovered.
