TO is not the same belief, and it is mainly divided into two factions, namely, the salvation faction and the arrival faction. The salvation school is represented by senior intellectuals. After learning about the civilization beyond the earth, they have all kinds of beautiful fantasies about it. To some extent, the Salvation School believes in three-body civilization. At first, the Advent Party was desperate for human beings to destroy other species. They no longer have hope for alien civilization. The purpose of their joining ETO is only to save the despair and hatred of mankind!
Internally, ETO has been controversial in its development: the Salvation School, based on the game "Three-body", tried to save the Lord they believed in, which was contrary to the Advent School. When the three-body problem is solved, the three-body people will not come to the earth, so the arrival faction regards the salvation faction as the biggest enemy, and even armed conflicts will occur in the later period!
Santi people understand that human thinking is closed, and even if they communicate face to face, what they say may be false. This really scared the three people into a cold sweat. They can't guarantee whether Evans is really loyal to the three-body, fearing that he is a super undercover of human beings. In the confrontation between the trio and human beings, the dark forest law is the only way for human beings to balance the trio. Since human thinking is closed, no matter you are ETO or WTO, anyone who knows the laws of the dark forest is the biggest threat to the three-person body and must be removed quickly. Finally, the trio abandoned ETO.
