"Once it was for profit, now it is for righteousness; use insects as blades, use darkness as clothing, return justice to the weak, and pay off the evil debts of the world."
Lin Yan, an ordinary conscript, retired. After returning home, he repeatedly encountered obstacles in finding a job and lived in embarrassment. When he went into the mountains to collect medicine, he accidentally discovered a fallen alien meteorite, from which he obtained a mysterious crystal embedded with a star core. After touching it, the star core was automatically implanted into the brain, activating the nanoworms simultaneously. In order to get rid of poverty in the early days, Lin Yan used the special ability of the star core nanoworm to make money and immersed in the satisfaction brought by money; until he witnessed the destruction of families persecuted by "poison needle loans" and the desperate cries of parents of abducted children, he was deeply impacted in his heart and his ideas completely changed. Since then, he has hidden his identity and walked on the edge of darkness, specializing in helping those who were victimized by criminals and had no way to turn to help, and fought against various dark rules covering rent-seeking of official power, black gold trading in shopping malls, rampant local tyrants, and cross-border crimes.
