Top programmer Shen Ci accidentally traveled to the world of "Detective Conan" and became a low-level outsourced coder trapped in the surveillance of a dark organization. Facing the "big purge" of the organization at the beginning, he awakened the "skill point system". As long as he participates in the case or affects the progress of the main line, he can obtain skill points and infinitely strengthen his professional skills. Shen Ci used hacking technology to invade the winery's database, assumed the pseudonym "Code Walker", and repeatedly jumped between the red and black sides. Not only did he save the police academy team that was supposed to die, but he also secretly established a global surveillance network, turning cases that originally relied on traditional detection into a game of information flow. With the accumulation of skill points, he evolved from a weak programmer to a behind-the-scenes hacker king capable of fighting, shooting, and profiling. Finally, in the battle of Tokyo Tower, he personally ended the organization's utopian dream with a closed-loop logic.
