A calm and keen game security analyst who hides the secret of pursuing the truth) <Lu Chengxiao> (Male protagonist: President of the technology giant "Starway Interactive Entertainment", the man behind the game "Ember Night") {A holographic game called "Ember Night" was born. It monopolized the market three months after its launch. However, on the night of the celebration banquet, the mysterious death of the first player was revealed. The death condition of the deceased was exactly the same as the punishment for failure in the "Ultimate Mission" in the game. No trace of external force was left on the scene, only a string of strange game codes remained. Su Yan, a game security analyst, took the initiative to intervene in the investigation because his sister's disappearance three years ago was inextricably linked to "Ember Night". She discovered that the deceased had triggered undisclosed hidden plots in the game during his lifetime, and the person behind it all was none other than Lu Chengxiao, the president of Xingtu Interactive Entertainment. Lu Chengxiao is mysterious and secretive about the hidden mechanism of "Ember Night", but he takes action many times during Su Yan's investigation, sometimes helping and sometimes testing. As the investigation deepened, more players died in the form of "game punishment". Each case pointed to fatal loopholes in the game code, and behind the loopholes, there seemed to be a conspiracy spanning three years. Su Yan works step by step in the intertwining of virtuality and reality. Lu Chengxiao's true purpose, the truth about his sister's disappearance, and the fatal secret of "Ember Night" gradually emerge in the fog of code. A cat-and-mouse game involving life and death begins between the keyboard and reality.
