Although Yan Fei is concerned about the safety of all humanity, he did not promote the hard-won Grand Unification Theory nor did he have the idea of bringing everyone together to develop. He believes that the main reason for the current chaos in the world is that everyone's technological level is very close, resulting in military strength being very similar, which gives some countries room for imagination.
If a force with technology far surpassing other countries appeared on Earth, under its powerful military suppression, other countries would have no hope and would then abandon creating chaos, becoming truly united to face a strong enemy together. Therefore, Yan Fei instructed Yang Qi that the Grand Unification Theory must remain confidential and must never be leaked.
