Advanced alien civilizations use the spontaneous gravitational wave resonance characteristics of stars to link the entire universe into an interstellar network. When an alien meteorite lands on the earth, Li Mu accidentally obtains a connector linking to the interstellar network. Bio-chips, flying cars, super batteries, nuclear fusion energy, interstellar spaceships, ..., there are endless alien technologies on the interstellar network. Li Mu's eyes are bright, download, download..., start high-tech companies, establish multinational groups... , to build a moon base...,. Oops! Not good, the more you play, the bigger the game, what should you do if you can’t keep it!
