In the mechanical city where steam and gears roar, ordinary mechanic Chen Mo accidentally obtains the "soul card drawing system" - he can exchange souls with the drawn card characters and obtain all their abilities. However, he discovered that the city's card drawing system was actually controlled by a mysterious organization. All card pools had been manipulated. Commoners could never draw divine cards, while elites relied on cheating to monopolize extraordinary abilities.
When Chen Mo drew an abandoned "Machine Queen" card, he not only obtained ancient mechanical technology, but also gained insight into the ulterior conspiracy behind the system. It turns out that the controller uses black technology to modify the probability of drawing cards. Every time the card drawer consumes an opportunity, his lifespan is absorbed by the system by one point. The human beings in the entire Mechanical City are slowly being drained of their life essence!
Chen Mo decided to use his soul exchange ability to infiltrate layers of conspiracies and uncover the true identity of the controller. But every time he uses his ability, his soul will resonate more and more strongly with the card character, and if he is not careful, he will be trapped in the card by the backlash. Under the siege of mechanical behemoths, steampunk monsters and the Iron Holy See, how will he crack the shady system and save this doomsday city on the verge of collapse?
