Close your eyes and think about the black technology of the next seventy years. A question in class solved the shock cone equation that a German professor had not solved for fifteen years.

Someone offered an annual salary of 100,000 US dollars: "Stay, you will be the second von Braun." Someone put a knife on his neck: "If you don't come with us, you will never leave." He fled from Munich to Hamburg and from the North Sea to the Mediterranean. Trains were blocked, ports were besieged, chased on the high seas, and destroyers fired warning shots. He narrowly escaped death and was covered in injuries just to cross the Luohu Bridge. After returning to China, he faced a very poor family. Short of bullets?
