Dream Reunion (Fan of the Demonic Patriarch)

Gu Yu loved "The Patriarch of the Demonic Way" and every flesh-and-blood character in the book, and was deeply saddened by the tragic ending of those people and those things. It would be nice if it could be changed. So Gu Yu traveled through time and gained deep spiritual power, sufficient property, accurate information, and a charming appearance. People who did not exist appeared in this world out of thin air in order to fulfill a dream. When she woke up from the dream, she couldn't help but wonder - was Duke Zhou dreaming of a butterfly, or was it a butterfly dreaming of Duke Zhou? Note: 1. CP is tentatively decided: Lan Wangji x Wei Wuxian, Lan Xichen It may be changed or added based on comments. 2. All the characters I like in the original novel will survive happily, so Gu Yu may be the only tragic character in this novel. 3. Gu Yu probably doesn't have CP. She was written just to help the characters in the original work live a happy life with the help of her eyes and hands. Consider happiness in the extra story. 4. The friendship between Yunmeng and Shuangjie is good, and their parents will live well and recognize each other (Wei Wuxian will still be an "orphan" for a few years) 5. Xue Yang and Jin Guangyao will be cleared. Jin Guangyao did not recognize his ancestors and returned to his clan, and grew up as Meng Yao, a disciple of the Lan family. Jin Zixuan became the head of the Jin family. Meng Yao's mother Meng Shi survived and was ransomed. 6. Lan Wangji's parents will survive and Lan Wangji's mother will be cleared.
