In the Doomsday Future, Humans Send Me World-Destroying Technology

Three hundred years later, humans in the future sent a legacy of world-destroying technology to Gu Heng. The first inheritance was his death certificate. The second reminder is that my sister Gu Ning is about to die in a subway collapse. Scanning disaster nodes, downgrading future blueprints, recycling waste technology, civilization contribution points... Every time he uses the legacy, Gu Heng can save the disaster in advance, but it will also advance the chain of annihilation. When he used a pile of scrap parts to prop up the station that was about to collapse and rescued the last batch of passengers, the terminal reward arrived. But the second package also appeared. Recipient: Gu Ning. In the future, Gu Ning only left one sentence: "The person responsible for the destruction of mankind is Gu Heng." This novel and its characters are purely fictitious.
