Reincarnation Rules

Lu Chen, a social animal programmer, said something to his ex-girlfriend when they broke up - "I don't think you have no money, I just can't see you working hard." He didn't defend himself, and then a pop-up window popped up on his phone: Invitation letter from reincarnation, do you accept it? He clicked reject and the screen went black. In the copy of the reincarnation system, other people's systems were based on skills and bonus points, but Lu Chen's system only gave one line - a silvery white one, extending from the center of his eyebrows, connecting everyone's cause and effect. The first person was a girl in the basement of an abandoned middle school. She repeatedly wrote a person's name on the blackboard and waited for eleven years for someone who didn't keep the appointment. The second person is in a city ruled by an algorithm. AI scores each citizen, and those who fail are taken away for "optimization". The line passes through the streets and underground, and stops in front of a still-running core, a still-living brain. Every time a copy is entered, the thread digs deeper into the bottom of the rules, and code that does not belong to this world begins to appear deep in the copy - someone left a backdoor when the rules were first written, waiting for someone who can read these codes. Until one day, the system popped up a prompt that was not in the task list: "Your causal type has been recorded, and the first two people with the same type of abilities have died - you are the third one!"
