The Trump Card with Unresolved Grievances in the World

Engineering City, the passage between the human world and the virtual world, a world where humans and gods coexist. Every resident here lives in his or her own "reality" and enjoys the "cruelty" that comes from the Industrial City that weaves all "reality" into one. Therefore, riots are the theme of this city; taboo is the charm of this city. Evil, despair, and depravity are daily life in this city, just like eating and drinking. However, Cheng Zijun couldn't stand it because of all the evil in this city. He wants to kill the "thought monster" who caused these crimes! For this reason, one has to become the "ace". From this, from the moment he becomes a trump card, the grudges between Cheng Zijun and the world will become more and more intense.
