Wen Xinya did not say that she wanted to kill Xia Ruya out of a moment of recklessness nor did she give it any deep thoughts. She merely followed her heart.
She was almost certain that Xia Ruya was the one who led the plot against Old Mr. Mo. Xia Ruya had already begun targeting Old Mr. Mo and, given her stubborn and goal-oriented character, she would definitely try and harm Old Mr. Mo again since she did not succeed this time. Wen Xinya could not take the risk and put her Grampy's life at risk.
Regardless of how vicious Ning Shuqian may be, she wouldn't dare to harm Old Mr. Mo for no reason. And no matter how afraid of Old Mr. Mo the Korean-Chinese Alliance may be, they wouldn't dare to act unless there was an opportunity to do so.
As long as Xia Ruya died, she would no longer pose a threat to Old Mr. Mo's life.
Wen Xinya would never allow anyone to put Old Mr. Mo's life at risk.
