Protagonist: Jiang Zhen Fan Yin
[Putting through books + the beautiful and powerful young master of the Demon Cult + healing and redemption + running in both directions + causing depression first and then sprinkling sugar]
To clear things up, the male protagonist in the early stage is cold-hearted and sinister. He is not a silly and sweet male protagonist, nor is he a refreshing heroine. Please don't criticize me for this, thank you.
Jiang Zhen went through the book and found herself in a Jianghu novel that was reviewed by everyone, including Fan Yin, the young master of the demon sect who was extremely beautiful and powerful but also miserable. He was a cold bone quenched from the sea of blood in the mountain of corpses, an evil god who could not see the light, but he was madly in love with her. He gave up the world for her, broke his pride for her, and was willing to fall into the endless hell for her.
After the book review failed, in order to survive, Jiang Zhen began a long road to redeem the young master of the Demon Cult. After experiencing countless trials of licking blood with the tip of a knife, she finally slowly opened the door to his frozen heart and became the only light in his dead world.
Depress first and then heal, going both ways is the sweetest thing!
