In 2187, the resource-depleted world relies on the "contribution value system" to maintain operation. Fan Qi, a former Yongyao Group engineer, returned to the bottom after the collapse of the "get something for nothing system" and ran a repair shop with his partner Lin Wan. When the remaining forces of Yong Yao launched the "Purification Project" of the third-generation mind control system, he, Lin Wan, and technical expert Su Yao went deep into the prehistoric civilization ruins under the Antarctic ice cap. While fighting against the mastermind code-named "Night Owl", they gradually revealed the truth that the system technology originated from ancient civilization. The work explores the ethics of science and technology, free will and the redemption of human nature through the main line of the protagonist's growth from being dependent on the system to breaking free from restraint.
