When I Wear the System

Once an ordinary girl is selected by a mysterious messenger, as long as she agrees to be a disciple of the Immortal Heaven, she will be immortal, have no worries about food and drink, and be paid well. What's even more outrageous is that if you save enough points, any wish you wish for can come true! The heroine signed the contract without saying a word and became the spiritual disciple of Changshengtian No. 36747129. Her job is simple: travel through various parallel worlds and become the portable system of the heroine of destiny, helping the heroine change the plot, avoid disasters, and stabilize the world line. In the beginning, she worked honestly, completed tasks seriously, upgraded and fought monsters along the way, and became the best among the spiritual disciples. Her life was relaxed and comfortable. Until a mission goes wrong and she comes to a familiar world. The moment she saw the villain in the book that everyone was shouting to beat, the heroine was completely confused - wasn't this the person I had personally protected and tried my best to save? For the first time, she began to wonder, what is the so-called longevity sky and the so-called system? She started to become rebellious, you want me to help the heroine take the right path? OK! Then I just teach her to be selfish, teach her to be sober, and teach her not to be manipulated by others. You want me to stabilize the plot? Then I will turn the plot upside down and reverse good and evil. Seeing that the world was about to collapse due to her toy, the mysterious messenger appeared again. After she was taken to Changshengtian and met the real master behind the scenes... Only then did I know what it means to have all the mechanisms, it is better to have a light stroke of fate...
