They're Not Wrong

The Old Marquis believed that he had made a significant concession and hoped that Su Bin would understand his position.

However, Su Bin remained resolute.

Su Bin was not willing to simply let go of the Old Marquis' equal wife. Nevertheless, her private execution was of little consequence to him.

What Su Bin truly desired was for the Old Marquis to admit his mistakes and publicly reveal the truth about his father's departure from home.

The private execution of the Old Marquis' equal wife held no bearing in Su Bin's grand plan. If he wished to press charges against her in a court of law, he could have her sentenced as he saw fit. The act of a concubine murdering her primary wife typically warranted a death sentence by hanging.

Su Bin aimed to make everyone aware of the methods this woman had employed to cause his grandmother's death and compel his father to leave.
