The Days After Becoming the Concubine of the Demon Lord [Puishu]

Qingyu wore a book, but it was the wrong book. The system told him that after traveling through the book "The Demon Lord's Little Wife", he must become the male protagonist and make the Demon Lord love him to death. When Qingyu hummed and betrayed his appearance, the Demon Lord suddenly called out "Master..." Qingyu: "???" System: "Didi, the virus has been cleared. It is now detected that the book worn by the host is "The Demon Lord's Road to Revenge". The host's identity is the Demon Lord Master, who is the Demon Lord's biggest enemy." Qingyu: "???" —— In his previous life, Lu Wenyu listened to his master's words and sneaked into the Demon Sect alone, almost losing his soul. After going through all kinds of hardships and becoming the new Demon Lord, when he was about to dismiss the Demon Cult members and teach them the right path as his master said, he was pierced through the heart by his master's sword. Before returning to teach, Lu Wenyu finally saw the true face of his master. He was just a stepping stone for his master. In this case, he would capture the master. Humiliate him. Trample him. But... Master... Why are you taking off your clothes? The vengeful Demon Lord blushed with shame.
