After Half a Lifetime of Hard Work, I Came to the Devil with Resentment

In the past, she was a sect saint with outstanding talent and pure heart. She suffered many hardships for half her life: her best friends backstabbed her, her lover betrayed her, and the sect made her an outcast for profit. All the blood and grievances accumulated in her heart. When she fell into despair, she was filled with resentment and broke the shackles. The saint fell into darkness and ascended to the position of the eternal demon lord. By chance, she tamed an exclusive beast that was smart and agile. The beast usually looked cute and harmless, but it was also a reliable substitute: it could offer advice on the spot to break the situation, and it could also complain about various villains in a fancy way, creating a full contrast of cuteness next to the ruthless and murderous Demon Lord. She will personally sort out all the bullying and calculations in the past. The sharp blade is unsheathed to crush the old order, and the resentment gathers strength to sweep across the enemies in the sky. Let's see the female demon king, who has been burdened with half a life of suffering, walks with the divine beast, uses the magic flame to overturn the shackles of fate, and lives a peak that no one can shake.
