A scientist said that the most ideal form of living for human beings is to live underground. We thought it was a joke, but we didn't expect that all countries really started spending huge sums of money to build "underground cities." The Oriental Dragon Kingdom spent 40 trillion yuan to build an "underground city" project that can accommodate 20 million people. It is expected to take two years to build. Chu Ziye stood up: "One month!" The whole country was shocked. No one can believe that someone can complete such a super project in one month. However, thirty days later, the "underground city" that could accommodate 200 million people was completed, shocking the world in one fell swoop! Immediately afterwards, orders came for the underground high-speed rail tunnel connecting Europe, Asia, and the Philippines, and the order for the 20,000-kilometer-long "Great Coast Wall" came. At this moment, everyone suddenly realized something was wrong. These "underground city" projects don't seem to be used for living, but for doomsday shelters. The end is approaching, and a global war has begun. … The introduction is weak, let's read the text! This novel and its characters are purely fictitious.
