Sophon is an intelligent microscopic particle made by three body humans unfolding protons in two dimensions and etching circuits. After discovering signals from the solar system, the Trisolarans launched the "Zhizi" project: expanding protons from eleven dimensions in two dimensions, etching circuits on them, and transforming them into intelligent computers, allowing the protons to acquire artificial intelligence and be controlled through terminals. After completing the construction work of four Wisdom Sons in the Three Body World, these four Wisdom Sons were divided into two pairs. One pair was sent to Earth at near the speed of light, while the remaining two remained as communication tools in the Three Body World. The purpose of building Wisdom in the Three Body World is to monitor humans for a long time without blind spots and lock in human technology.

Therefore, the goal of our group is promoting the development of science and prevent the damage of Zhizi produced by Three-body livings.
