On the Eve of Death, I Raised a Boss

Question: If you met a young villain, the Demon Queen, who had a tragic life and was alone and helpless, what would you do?

A: I will lend her a helping hand, offering her meticulous care and warmth. I will strive to make her feel the kindness and beauty of the world, doing everything in my power to improve her favorability towards me. However, my goal isn't simply to increase her favorability; I sincerely hope she can have a happy childhood and a bright future.

Gu Qingchen traveled to a novel world and became a cannon fodder character who would be killed by the protagonist soon.

To change his fate, he decides to embark on a journey to become the future Demon Cult Empress. The road won't be easy, but he's willing to work hard to save the young Empress for his own future. He'll use his actions and sincerity to move the Empress, earning her trust and reliance. In the process, she'll continue to grow and improve... until one day, Gu Qingchen dies before her... (The plot of this book is a bit slow. After the male villain dies, the female protagonist will destroy the world in the second volume, and the male protagonist will be resurrected. There's a system in this book, but it's not very strong. It has a single female protagonist, unlike other stories, and uses a micro-group portrait style.)
