Yang Lina immediately tried to call Xuan Hui to ask him not to do anything drastic. Now that Yang Lina is sure that Lily is targeting Xuan Hui, she's decided to go back to Hong Kong to protect her son. Unbeknownst to her, Lily has already laid down a trap for Yang Lina.
Hong Kong is just a few hours drive from the Yang Mansion in Mainland China. Throughout the ride, Yang Lina was thinking of a way to get back at Lily. Since the Yang Family has already abandoned her, she needs a new method to deal with a woman like Lily. Of course, using Tang Lingyun was her first plan. Or maybe she could attempt to dispose of Lily. Realistically, that would be hard to do with Zhuo Jingren around.
"Why did you stop?" Yang Lina asked her driver when she noticed the deceleration of the car.
