Chu Ranran, a thousand-year-old nine-tailed fox, trusted his best friend in his previous life. His fox core shattered and he died tragically in the abyss. Reborn one year before the disaster, she gave up the charm technique used by the fox demon and relied on the memory of her past life to take revenge through illusions and nine-tailed movements. There is no CP in the book. The heroine concentrates on fighting the enemy with her wits, punishing all kinds of monsters, and planning every step of the way to make the betrayer fall into the long-term torment of regret.
