Intro: After the college entrance exam, his parents went on a sweet vacation, leaving Jing Mingqiu alone to guard the repair shop. Fortunately, he awakened a black technology system. As long as it's a technological product, anything can be modified! "Brother, help me modify a drone. Make it more stable, and faster!" "More stable, faster? Understood!" Jing Mingqiu immediately hand-crafted a 5nm lithography machine and etched ultra-precision chips! "This should be enough, right?" "Hello, may I ask if you are Jing Mingqiu's father? Your son has produced a 5nm lithography machine and has now been invited by the Academy of Sciences experts to improve the new generation of fighter jets. As his guardian, if it's convenient for you, please come over to sign." "I asked you to watch a shop, and you ended up at the Academy of Sciences?!"
