The Demon Lord and Her Creator [Through the Book]

It's a bit troublesome to explain, but in short Gu Jinli has traveled through books and into the first novel he wrote. The good news is that there is a system and a cheat. The bad news is that the survival rate of ordinary people in this novel is 0... Perhaps considering that Gu Jinli is a weakling, in order to prevent her from falling into a box, the system gave her the most incredible golden finger - immortality. Such a heaven-defying golden finger made Gu Jinli extremely happy. Unfortunately, the heroine she wanted to conquer was Shen Chigui, a demon who kills without blinking an eye and likes to torture people in various ways. Gu Jinli: "..." Is it still too late to make a substitution? - Shen Chigui found that the world was very strange. There would always be some inexplicable people coming and doing inexplicable things to him, such as being extremely attentive. At the beginning, Shen Chigui would kill the opponent impatiently, out of sight and out of mind. But after doing it more times, she gradually discovered the truth of the world. The world she lives in turns out to be just a book, and she is just a character in the book. Her identity, name, personality, time, and even cognition are just a few lines of words randomly assigned by one person. Shen Chigui was shocked. Shen Chigui was extremely happy. Shen Chigui completely let go. She began to target the Raiders and the world, vowing to poke a hole in the sky to see if it was true. Later, time was traced back, and Shen Chi returned to the age of nine, when everything had just begun. But this time, she met a very magical woman. That woman claimed to be her creator, and she couldn't survive no matter what. It was so interesting. Oh. Creator. Interesting. …… Many years later. Gu Jinli looked back on the past with the heroine, and summarized it in one sentence - Being killed by the heroine ten years ago, life was worse than death. Being slept with by the heroine for the next ten years would be worse than death. Feelings: What a brilliant and beautiful life! ***Food Guide*** 1: No modification or reprinting is allowed.
