Renegade Immortal (WN) - Chapter 24: Cultivation

Everyone told Wei Yingluo that her sister had taken her own life. But the mark left on the corpse told a different story. To unearth the truth, she entered the Forbidden City during Emperor Qianlong’s 6th year of reign.

After investigation, she found her sister’s death related to Prince Hongzhou, and became determined to avenge her. The kind Empress Fucha, worried that Yingluo would stray onto the wrong path, took her under her wing. With the help of the Empress, Wei Yingluo grew to be an honest and strong female official in the palace, letting go of her resentment and living her life seriously from then on.

Yet the Empress passed away unfortunately, causing Yingluo to misunderstand Emperor Qianlong. Hostile against each other, could they understand and support each other in the end?
