At the cracked boundary of time and space, Su Guichen awakens from the void at the end of the universe - he is both a hero and a villain. With each reincarnation, his memory is fragmented, and his identity wanders between salvation and destruction. The future world is ruled by an intelligent matrix, and all life is just a variable in the data flow. However, Su Guichen possesses the only abnormal code, which can break through the system settings and rewrite destiny. He longed to find himself, but had to sacrifice and be reborn repeatedly under the calculations of the matrix. The core conflict is: Su Guichen must choose whether to become the "savior" given by the matrix or the "destroyer" who ignites free will to end this endless reincarnation. The novel is intertwined with multiple time and space, fragments of consciousness and technological philosophy, exploring the boundaries and essence of heroes and villains. Every decision Su Guichen makes reflects the abyss and hope of the human soul in the light and shadow of the future city.
