Just Rub a Nuclear Bomb in Your Hand, Police Uncle, Will You Arrest Me?

[Black technology + waste recycling + national important weapon + relaxed and funny + high energy throughout the process] Su Yun traveled through the parallel world and became a college student who was slandered by the school and dropped out of school. Go home and inherit the second uncle's scrap station, and awaken the [Truth Analysis System]! Everything can be analyzed and everything can be upgraded! Customer: "Boss, my battery car has poor battery life. Can it be changed?" Su Yun: "No problem, add a micro nuclear fission battery and it will last for 100,000 kilometers." Customer: "Boss, I want to go on a polar expedition. Do you have any cold-proof equipment?" Su Yun: "This nano-steel suit is suitable for you to wear. It's bulletproof, anti-freeze and anti-nuclear explosion." Just when Su Yun was obsessed with rubbing black technology at the scrap station, an unexpected test explosion led to a special police encirclement and suppression. "Hold your head with both hands! Don't move! Put down the weapon in your hand!" Su Yun looked innocent: "Uncle policeman, I'm just going to fix a microwave oven, so I don't need to dispatch the anti-terrorism force, right?" Until the military boss arrived and looked at the electromagnetic guns, air and space fighters, and two-way foils all over the yard... The boss held Su Yun's hand tremblingly: "Gong Su, the country needs you! If we can't go to school, we can directly become the president of the Academy of Sciences!" Yingjiang: "Protest! Dragon Kingdom is cheating! Why are their fishing boats equipped with photon weapons?" Long Guo: "Nonsense, that's just a fishing trap made by Su Yun."
