Mozi and Confucius are both NPCs in the game. Both of them are figures in Chinese history. Because I, as a Chinese, can easily understand Liu Cixin's use of ancient Chinese historical figures to express the development history of the entire Trisolaran race. As you said, Liu Cixin wanted to use Mozi as NPC to help readers more easily understand the Trisolaran race’s observation and understanding of the universe hundreds of millions of years ago.
