Yang Jingxuan was sent to lurk in the "Silicon-based Flow" project. It looked like cold smart materials on the surface, but behind it was an emotional algorithm that could get out of control. After a mission failed, he was accidentally bound to the same "safety isolation agreement" with Zhou Wanqing. Recovery became the price and a breakthrough. Just when he thought he could stabilize the situation, the system began to learn from humans in reverse: lurking undercover, spreading out of control, and getting closer to the truth. All gentleness turned into danger signals.
