Urban: Ghost Helps Me Design a Photolithography Machine

College student Li Wen tried an out-of-body experience at home, but ended up bumping into a ghost. Thanks to Li Wen's strong social talent, one person and one ghost chatted, and the ghost said that he could answer any questions Li asked. Driven by curiosity, Li Wen asked for the design drawings of the photolithography machine. "What? Lithography machine? I'm just a cultural and entertainment person. Wait for me to contact someone in science." "Lithography machine? Is this country's technology not at the forefront of the world? I will take over this matter!" "Old Li! Call a few more ghosts over, we must take down this technology!" "Today, even the abacus must produce this data! The country must have this technology! We cannot fall behind anymore!" After a while, Li Wen's home became terribly cold, and countless ghosts calculated data in front of Li Wen. This novel and its characters are purely fictitious.
