The Villain's Second Senior Sister's Guide to Immortality

Copywriting Wen Beitang practiced diligently in his previous life, and only before his death did he find out that he was the villain of the Second Senior Sister in a book about cultivating immortals. She treated her sect brothers with all her heart, using the gems from the deep sea to replenish his sword, and using her own spiritual pearls to nourish the elixir for the seriously ill junior brother... But when she was framed and about to have her veins cut off, none of her brothers and sisters were willing to speak for her. All she got was an indifferent sentence: "She deserves it." After practicing for hundreds of years, it is really ridiculous to live. After the punishment, the only trace of her soul was exiled to the world. During the few years of wandering in the world, she tasted all the warmth and coldness of the world. The only person willing to lend a helping hand to her was the slave she rescued in the slave market a hundred years ago, and is now an important minister in the court - Wan Qiyuan. After learning about her experience, Wan Qiyuan sat in her wing for a long time and left a message before leaving: "I will help you get this justice." Unable to wait for the day of seeking justice, Wen Beitang opened his eyes again and was reborn a hundred years ago... This time, she held the sword and climbed to the top of the cultivation mountain to personally seek justice from her previous life. —— Wan Qiyuan was cursed with a slave curse, transforming himself from the demon crown prince above all demons into a slave that everyone can trample on. His memory was wiped out time and time again, and his self-esteem and pride were gradually crushed in the ordeal. Just when he was about to give up on himself, he met a beautiful girl. At that time, he had just been beaten, covered in blood, and locked in a dirty cage, like a downtrodden beast. The girl standing in front of him had a beautiful appearance and spotless clothes, which was incompatible with the dirty slave market. She looked at him in front of the cage for a long time, pointed at him and said to the people around her: "I want him." Later, she gave him food, respected him, and tried her best to break the slave curse on him. Later, he reopened the bloodline of the Demon Emperor, regained power, and tried his best to protect her forever. Intention: love yourself
