The butler was probably trying to persuade him because he didn't dare to do it, so Old Master Meng wouldn't ask him to do it. He had to do it himself.
With Mu Huan's current status, he could only succeed the first time. Otherwise, he would be the one to die. He was not afraid of death, but he had to drag Mu Huan down with him!
She had ruined his honorable life and made him old only to be mocked like this. If he could not kill her, he would not die in peace!
After getting into the car, the butler thought about it and could not help but persuade him again, "Old Master, even if Young Master Bo is unfilial and doesn't deserve your heartache, what about Missy? Missy is already in this state because of you. If anything happens to you, if you… what will happen to Missy and Second Missy?"
Even if he didn't want to care about others, he had to think of his two biological daughters.
