[City + System + Black Technology + Border Support + Home Country + Apocalyptic Alien Invasion] In recent years, technological competition has become increasingly fierce. Some big countries even send spies for their own selfish interests, overt and covert theft, and deliberate sabotage.
Lin Chen, a college graduate, was selected to support frontier scientific research. However, during the border crisis, he activated a portal that could access future ruins technology. He accidentally summoned a small nuclear reactor and was included in the country's special strategic system. He then led the scientific research and special service team to reversely reproduce future high technologies and resist foreign forces' coveting of the portal. He also cracked the doomsday secret of the portal's "civilization spark cabin" and finally handed over all strategic-level high technologies to help the motherland become a global technological overlord and protect the continuation of human civilization.
