Appliance Repair Shop? Why Does the Military Purchase Goods from You?

Inheriting a scrap collection station that was about to close down, Ye Fan was bound to the [All Things Repair System]. I thought I could just live by repairing old appliances, but unexpectedly, the customers who came to my door became more and more outrageous! "Boss, my drone has exploded. Can it be repaired? Just fly it as you like." Ye Fan: "Yes." The next day, a "UFO" that could not be locked appeared on the Air Force radar! General: "Fifth generation engine + quantum communication + stealth paint?! You call this a repaired drone?!" "Boss, my scrapped submersible has a broken propeller. Please help me replace it." Ye Fan: "Okay." Half a month later, news came from the deep sea that the Dragon had lost contact. Navy Commander: "Supercavitation silent technology + 10,000-meter deep dive + electromagnetic drive?! You told me this is a new propeller?" Seeing the top secret reports written "Ye Fan Scrap Collection Station in Urban Village", the military bosses fell into deep thought. When a special mission team held the top-secret design drawings and opened the door tremblingly: "Old... Boss, look at this scrapped aircraft carrier..." Ye Fan grinned: "No matter what the problem is, just ask - it can be fixed!"
