After promising each other a lifetime together with the villain, his true identity was revealed.

Yin Xi transmigrated into a dark revenge novel for men because of her careless talk. She was a female cannon fodder who was torn to pieces by the young villain as soon as she appeared.
To avoid the tragic ending in the original story and to prevent the future villain from turning evil and destroying the world, she was forced to embark on a path to save the world. But she had only taken half a step when she rescued a handsome young man who was seriously injured and had lost all his memories. The young man mistook her for his older sister and clung to Yin Xi, acting cute and unwilling to leave. Yin Xi had no choice but to take him with her on her journey.
The road to saving the world is fraught with difficulties and dangers, but she and the boy accompany and support each other all the way.
In Yin Xi's eyes, the boy always had a smiling face and always tried his best to cheer her up when she was sad or frustrated. When they encountered danger, he would risk his life to protect Yin Xi, even if it damaged his cultivation.
It would be a lie for Yin Xi not to be moved, and it would be true that she was gradually developing feelings for him. But one day, the male protagonist of the original book found her and told her that the obedient younger brother beside her was Ji Yunyuan, the demon prince who was feared by everyone in the cultivation world, and the great villain who destroyed the world in the original book.
Yin Xi tried to escape in terror, but was held firmly by Ji Yunyuan, whose face was full of gloom.
"Where is my sister going?"...
Ji Yunyuan, wanting what Yin Xi possessed, meticulously feigned innocence and foolishness to stay by her side, all for the sake of putting on an act. But as the saying goes, even heroes have difficulty resisting the charms of a beautiful woman, and he ended up falling for her in his act.
He began to fear that Yin Xi would discover his original purpose and leave him because of it, but in the end, Yin Xi still found out and planned to run away.
But Ji Yunyuan would never give her a chance to escape...
"Guizhou, you are not God's sin, but God's innocence..."
"I'm not leaving. Will you love this world one more time?"
