Control the Tech Tree

Lu Xuan, a genius doctoral student, was plagiarized by his shameless tutor because of his revolutionary research results. He was framed and expelled from the academic world, and his life fell into the abyss. In his most desperate moment, in the old garage left behind by his parents, he accidentally obtained the "Human Civilization Technology Tree System" from high-dimensional civilization. This is a hard-core system that only provides theoretical knowledge and everything requires hands-on practice. Faced with a comprehensive international technological blockade and a domestic "stuck" dilemma, Lu Xuan had no choice. From graphene batteries to EUV lithography machines, from controllable nuclear fusion to space elevators... He started from the garage, using black technologies that crushed the times, and slapped all doubters and opponents in the face again and again. This time, he will personally take charge of the technology tree and light up the only way to the sea of ​​stars for his country and civilization!
