Bringing Alien Technology Back to Earth

Lin Yan, a maintenance worker in the mining area, picked up a shuttle from a distant star during a heavy rain landslide. After being accidentally activated, he was drawn into a rift in time and space and fell into the dying Zeta civilization. In the face of insect invasion, civil strife and energy depletion, Lin Yan relied on earthlings' engineering thinking and strategic wisdom to repair the defense system and help alien civilizations guard the last star gate. When he finally returned to Earth with the shuttle, he found that the alien enemy's signal had locked onto the Blue Star. In order to protect the motherland and mankind, he gradually transformed alien technology into real power, from energy, materials, medical care to aerospace, step by step to promote the motherland to break through the blockade and move towards the galaxy. But as the star gate opened again, Lin Yan discovered that the shuttle's fall to the earth was not an accident, but a screening experiment for lower civilizations. Can human beings escape the fate of being observed and dominated and truly become a member of interstellar civilization?
