Cui Wenshan just felt that once Fu Shilv arrived, she needn't panic anymore. Given his past relationship with Sheng Youxia, he couldn't just stand by and watch someone die.
Sheng Tianyi, still just a child, initially didn't realize how serious the situation was. But, clearly having been hit by Cui Wenshan just now, his eyes were swollen from crying.
As soon as he saw Sheng Youxia, he immediately tried to rush towards her, "Sister—"
Cui Wenshan grabbed his collar and yanked him back, pinching his back hard twice.
"Letting you not be so naughty every day," she scolded, "you just wouldn't listen, and now look, you've caused the death of everyone in the family."
Sheng Tianyi, tender and delicate, couldn't withstand such treatment and began hopping on the spot in pain, "Mom, stop hitting me, it hurts so much."
Sheng Youxia had long seen through Cui Wenshan's tactics, the harder she hit, the more sympathy others would feel, and they'd be unable to help intervening.
