Plot

Teenager Gu He joins Jinteng Group's experimental program and is admitted to Jinteng High School, a world-renowned institution, where he befriends the genius student Ye Wen. However, Jinteng High is shrouded in mystery, a young female teacher mysteriously disappears, and various inexplicable physical phenomena make Gu He and his friends sense something is wrong. When Gu He and Ye Wen escape the school, they discover that Jinteng High is actually located on a space station far from Earth. At the same time, Earth is plunged into chaos with widespread blackouts, wildfires, and mysterious stone tablets appearing worldwide. These tablets contain alien puzzles that defy human knowledge. Humanity launches the "263 Plan," turning the puzzles into exam questions for the gifted students at the space-based Jinteng High, hoping their exceptional learning abilities can unlock the secrets of the tablets. An accidental activation of a nanotech chip in Gu He's eye makes him the sole bridge between humans and the aliens. Together with Ye Wen and other students from different countries, Gu He works to solve the alien puzzles, eventually uncovering that Earth's crises are caused by aliens attempting to escape a helium flash to gather energy. In a life-or-death struggle, Gu He and his friends use an electron emitter to help the aliens escape, saving both the aliens and Earth.
