Ding Yi explains to Chen that those killed by macro-electrons, including his parents, exist in a quantum state that can occasionally influence the world when not observed. Disillusioned, Chen leaves the military research group. After building the weapon and forming a specialized military unit to use the device, they successfully deploy the weapon against anti-technology eco-terrorists who try to blow up a nuclear plant, but kill a group of schoolchildren that had been held hostage. They learn how to capture these macro-electrons and turn them into a weapon that can destroy targeted types of matter wood, stone, or even microprocessors. With the help of a theoretical physicist, Ding Yi, they discover that ball lightning is not formed by lightning conditions, but rather when lightning encounters 'macro- electrons' hypercharging the electrons until they express their energy. During his research, military technology researcher Lin Yun recruits him into a weapons development team. Both traumatized and inspired by that experience, he makes the investigation of ball lightning his life's work, first getting his PhD in the subject, then exploring the phenomenon through both applied and theoretical research. The novel follows the experiences of a first-person protagonist, Chen, whose family was killed by ball lightning while he was in high school.

In 2018 the English version, translated by Joel Martinsen, was published in the US by Tor Books. The original Chinese version was published in 2004. Ball Lightning ( Chinese: 球状闪电) is a hard science fiction novel by Chinese author Liu Cixin.
