This is a world of the future, where teenagers are usually most enthusiastic about virtual fighting games—arcade fighting. Everyone knows what an arcade is: the shape we have now is a display with a control stick and four buttons labeled A, B, C, and D below it. But in that future era, it's different. The arcade controller is usually stored in the duelists' card device and can be easily brought out when a duel begins. The basic shape of the arcade controller is similar to the ones we have now, but in the future world, the display uses light imaging technology and is installed on the control panel. The control panel is made using sensing technology. One side is for directional operations, and the other side is for attack-sensing keys, which you just need to lightly touch with your hand.
At the edge of the arcade controller, there is a card-swiping area. Each player selects a card of their fighter and swipes it there. The fighter is then displayed in reality through spatial imaging, but the summoned fighter is not a physical entity. The surrounding environment is digitized at the start of the fight to prevent conflicts with the real world.
The protagonist of the novel is a boy named You Ge, who lives in Fenghai City. His older brother, before dying, handed him his card—Guiyan—and hoped that he could participate in the National Fighting Tournament on his behalf to fulfill his last wish. However, things are not as simple as You Ge's brother imagined… This is an era of games that test skill and reflexes…
