Lin Beichen, the science top scorer in the college entrance examination, traveled to the end of the cyber world, where humans were imprisoned in steel cages by the Mechanicus and relied on "spirit stimulants" every day to survive. However, he discovered that the mathematics, physics and chemistry knowledge in his mind turned out to be a lost and taboo black technology in this world! Others rely on mechanical modification to survive, but he relies on his hands to make nuclear fusion reactors. When the Mechanicum's combat weapons came to the city, and everyone was waiting for the savior to arrive, Lin Beichen silently assembled the quantum rail gun: "Who said that academic masters can't save the world? I'm just a scientific researcher." But when he cracked the secret of the interstellar coordinates, he discovered that behind this apocalypse was a genetic screening test launched by a higher civilization - and he was already the final prey of this game.
