Doomsday Infrastructure: I Built a Mecha

At the beginning, Wang Duo obtains the Heart of Knowledge system and predicts that the doomsday disaster is coming! In order to survive in the world after the cataclysm, Wang Duo built a mecha. Just in time for his PhD defense, Wang Duo decided to make his prophecy public to the world to remind the country to be prepared! "What? The planet will no longer be suitable for human survival in three years? Isn't it funny?" Faced with the doubts of countless people, Wang Duo smiled and said: "I can't prove the end of the world, but mechas can!" With a loud noise, in front of everyone's horrified eyes, a giant mecha fell from the sky, causing an uproar around the world! Then, the catastrophe began, with melting glaciers, rising sea levels, global cooling, and magnetic pole reversal... The working exoskeleton, low-temperature fusion reactor, quantum chip, and interstellar solar sail developed by Wang Duo were exposed, shocking the world! Finally, when the catastrophe came, the Chinese people living in the underground fortress said that we were not panic at all! This novel and its characters are purely fictitious.
