I Built a City in the Last Days

I don't know how many years ago, the virus broke out again, and the world's population was only 6% of what it was before the catastrophe. Fortunately, scientists discovered a new energy source during the catastrophe, Guan. This is something that violates the laws of physics and can be transformed into all elements in real life. In order to control this energy, the government developed a chip that can materialize data and provide a series of services such as architectural design drawings. A total of 100 chips were implanted into important personnel and dispatched to various surviving cities to preserve the remaining territory. This novel and its characters are purely fictitious.
