At This Moment, the World Has Entered a Century of Catastrophe

Build a closed city and adopt a double wall system. Qin Feng, who traveled back from the future, experienced extreme heat and cold, large-scale volcanic eruptions in many places, large-scale tsunamis in many places, and other disasters. These disasters have brought the era of mankind to a complete end, just like the era of dinosaurs. In his previous life, even at the moment of death, he did not say that confession. This time, he not only wanted to say it, but even, for her, Qin Feng wanted to save the entire world. This novel and its characters are purely fictitious.
