Yun Shuangshuang thought over and over, and the only way to deal with Liu Zhen without confronting Liu Man Ni directly was to target Liu Cheng.

Liu Zhen's ability to choose whatever role she wants and work as much as she wants each year is inseparable from Liu Cheng's substantial financial support.
