Card Draws and Crime Solving: The System Paired Me with My Archrival

Being an overworked corporate drone is bad enough, but Xu Yin gets dragged into an endless game with her nemesis and boss, Lu Yan. To keep leveling up, she has to solve one bizarre case after another.

In the first game, Xu Yin and Lu Yan are matched as opponents. The winner levels up, while the loser gets a straight-up game over! They appear to cooperate, but beneath the surface, tensions run high. Xu Yin unlocks a System and gains a useless skill: Lucky Capsule. Her first pull is actually an "Invisibility Card for the Men's Restroom"?! Meanwhile, Lu Yan has every golden finger imaginable. On top of getting both a black and a white System, he also stacks an invincible good-luck buff!

It's a game of wits with the odds stacked against her. How can Xu Yin use her useless skill to break through and defeat Lu Yan?

As the game keeps leveling up, more and more players join, and the cases grow increasingly difficult. Amid these battles for life and death, layer upon layer of mysteries begin to unravel.

It turns out that the players aren't the only ones solving puzzles in this game. Every player is also part of the story. Who holds the key to the final mystery?
