The core of Zhizi Engineering is to unfold the nine dimensional proton two-dimensional and etch the circuit on the unfolded plane. This engineering plan was prepared by the Trisolarans civilization to invade the Earth civilization by locking in human technological development before the arrival of the Trisolarans First Fleet on Earth 400 years later. ​Therefore, the goal of our group is promoting the development of science and preventing the damage of Zhizi produced by Three-body livings.
