Jiang Biyun could not contain her rage, "Monster!"
She grabbed the insulated cup from the desk and hurled it towards Ming Yao.
That throw looked as if it would crack Ming Yao's forehead.
Ming Yao caught a glimpse of Ming Wan standing at the door through the corner of her eye, and just as the insulated cup was about to hit her, she swiftly dodged aside.
With a bang, the insulated cup struck Ming Wan's forehead.
"Ah!" Ming Wan cried out in pain, clearly not expecting that the insulated cup thrown by her mom would hit her in the head.
A thick liquid flowed down from her forehead, and Ming Wan's complexion turned pale.
The incident happened so fast that both Jiang Biyun and Sister Jin were taken aback.
It wasn't until Ming Wan cried out in pain that they snapped to attention.
"Wanwan, are you alright?" Sister Jin hurriedly helped Ming Wan to sit on the sofa.
