Xu Hao walked out of the studio and didn't go far.
Sun Hongmei was indeed really sick, but that didn't mean she was no longer dangerous. In fact, it indicated that, to achieve her goals, she would resort to any means necessary, even if it meant substantial self-sacrifice to damage her enemies.
When Xu Hao overheard Sun Hongmei's phone conversation with someone, he instantly realized that the person was definitely an Islander, as Elder Chen had described!
He despised Sun Hongmei even more for not only being a traitor but also being thoroughly despicable and debased. Couldn't she just be a decent person? Did she have to stoop so low as to be someone else's lackey?
The content of their conversation seemed to suggest that the purpose of getting Xu Hao out of the way was to kill him.
