In "Three-body", I feel that he led natural selection to escape from the earth for a reason, because in the second part of "Three-body", Zhang Beihai successfully hijacked natural selection and fled to outer space. At first, he was regarded as a traitor to mankind, but in what happened later, the fact that water droplets destroyed human warships made people realize that Zhang Beihai actually kept precious fire for mankind.

After that, the officers and men of "Natural Selection" and four other warships chasing "Natural Selection" all surrendered to Zhang Beihai. Five warships, a * * * 5500 people, joined forces to form a starship Earth, and five captains formed a committee. Zhang Beihai was elected as the chairman of the Power Committee, who holds the supreme power of the starship Earth. However, Zhang Beihai rejected the appointment. Someone asked him why, but he didn't answer.

Later, I learned that he gave the captain position of "natural selection" to Oriental Xu Yan, and the requirement was to restore the authority of the captain of "natural selection". He did this because Zhang Beihai was actually the leader and supreme leader. It is useless for him to choose. If he chooses, there may be many disadvantages.

Therefore, he thinks it is not necessary, and it is not conducive to the future survival and development of starship earth. The doomsday war has brought great fear to mankind. For the officers and men on the five warships, in fact, he had already predicted Zhang Beihai, where the human beings would lose, and then he became their spiritual leader. Whether he takes the position of commander-in-chief or becomes chairman will not actually affect his highest position, so he fled the earth in order to keep a fire.
