Ye Yun obeyed his master's order to guard the Demon-Locking Tower for three hundred years, day after day using his essential blood to maintain the seal, and his cultivation plummeted from Nascent Soul to Qi Condensation. When the three-hundred-year term expired, his junior sister Jiang Zhiyue took over as sect master, but incited by Lu Feng, she concluded that Ye Yun fabricated the demon disaster and embezzled resources, publicly humiliating him and giving him three days to leave the sect. Heartbroken and disillusioned, Ye Yun withdrew his cultivation and essential blood from the tower, lifting the seal. The Nine-Tailed Celestial Fox broke the tower to acknowledge him as master, lingering with tenderness. Other transformed great demons successively emerged into the world, and the Moyun Sect plunged into a catastrophe of annihilation. Only then did Jiang Zhiyue realize how absurdly wrong she had been.
