The Rise of Green Mountains

The End of the World, Traveling to and from the Earth (The Earth Is Left Alone), High Technology, Unholy

I want to read a book like "Seven Billion People Traveled Through the End of the World, Only I Can Return to Earth". I dare say that there is no such thing as a good book. Those who dissatisfied will throw the book in my face. Time travel and high technology support the main line of the mission. The protagonist has clear goals and decisive means. The former focuses on personal life.
