Linda did not dare to harm Old Madam Mo, so even when she got the vial, she did not do anything.
But then a few days later, she got a message saying, "........". Which made her scared was the photo attached to the message. It was a picture of her mother, her forehead wrapped in a white bandage.
"Did they harm her?" This was the first question that entered her mind. Fearing for her mother's life, the next morning she decided to inject the solution in Old Madam Mo's IV drops.
But Yun Xi caught her at the exact time.

Yun Xi went straight to their room. Inside, Mo Shan was tying his tie.
When he saw her walking in, he smiled and said, "You are on time. Help me..." with my tie. He wanted to say that, but the rest of the words died down in his throat as he found her in deep thinking.
