The information Aunt Zoe sent was even more detailed than Su Ying expected.
It is said that she was once a comrade who fought alongside her father and mother in the Southern Cross. Much of the bionic technology being promoted and popularized today was brought out from the Southern Cross by them. Another part of the data detailed the relationship between the Soviet Union and the United States before the catastrophe, as well as the 'Star Wars' program that affected the fate of humanity at the time. Amidst the full-scale confrontation between the two superpowers, the Star Gate project was merely a less noticeable sub-project. During the Cold War, both the Soviet Union and the United States embarked on some even crazier projects. (Note: The Star Gate project was a real-life psionics program.)
As for what happened later, there's not much to say.
