You Say You Have a Good Grasp of the Industry, but You Engage in Dragon-Slaying Black Technology?

In the parallel world, Shen Shenxuan unexpectedly obtained black technology, started a private enterprise, and grew bigger and stronger step by step. Exactly one day, a drone accidentally entered the Yingjiang aircraft carrier group, and the world was shocked. Eagle Sauce: Are there still drones in this world that can evade our radar detection? This is impossible! This is impossible! Dragon Kingdom: The equipment that the Dragon Academy of Science has not finished is actually for civilian use? Also used for express delivery? Check it for me! Conducting industrial surveys across the country... When the country issued a notice, Shen Moxuan was dumbfounded: I just developed some black technology for civilian use, how did it become top-secret military technology? Not only that, as the investigation deepens... Aircraft carrier arresting cable, T40 fishing rod, stealth car paint, laser wood saw... Long Guo: OK, OK! Is that how it works? It's all said to be for civilian use, but it's all dragon-slaying black technology, right?
