Synopsis
In the year 2048, the Lingyun system is set to be piloted in the city of Mirage as the first case of "smart brain popularization application." An accident at the Lingyun system conference that day triggers emotional complications among its creators Zhou Tong and Zhao Feibai, as well as childhood friends Ayigul and Aizmat. To achieve his objectives, Zhou Tong seals the "brain consciousness" of Zhao Feibai, Ayigul, and Aizmat inside the Lingyun system's sandbox space, but inadvertently activates the system's original intelligent AI—Lucoco. Everything is linked to the "imprint" game from the memories of the four people that year, an intelligence crisis coded as "human heart fetters" unfolding between reality and the virtual world.
