Chang Qian was once a talented young man in the e-sports circle, but suddenly disappeared at his peak. Three years later, he reappeared in the city's neon scene wearing a peaked cap, his fingertips tapping out breathtaking rhythms on the keyboard. This time his opponent is no longer a virtual character in the game, but a behemoth entrenched in the shadow of the city. Chang Qian is burdened with the truth that his family was framed, and an unknown power - he can sense and affect electronic systems in the real world through keyboard operations, and can even predict the actions of his opponents for a short time. When the passion of youth meets the cold reality, and when e-sports talent becomes a weapon to unravel the shady story, he must create a symphony of light and darkness for the city between the keyboard and the sound of gunfire. With the awakening and improvement of his abilities, Chang Qian gradually discovered a greater conspiracy hidden behind the city, a mysterious organization that controls the lifeblood of the city. With the help of his childhood sweetheart Su Qing and the mysterious hacker Lin Yue, Chang Qian began a counterattack against the dark forces. No one knew what this silent young man was carrying until he made the whole black and white community remember the legend - when his fingers started to dance, even his fate would be rewritten.
