Supersonic Drones, Do You Think They Will Be Used to Deliver Express Delivery?

Lin Yu, the second generation of rich people: "I want to participate in the technology venture capital meeting in six months, so I want to ask you to help me design a large drone!" Chen Mo: "Do you have any requirements?" Lin Yu thought for a while: "The first one needs to be big, and the second one needs to be fast. I plan to use it to deliver express delivery in the future, so it will carry much more weight." Chen Mo nodded: "Okay, it needs to be bigger, it needs to be faster, and it carries a lot more weight." Half a year later, Z Technology Venture Capital held its meeting. When a large drone with a total length of 20 meters, a height of 6 meters and a wingspan of 30 meters breaks through Mach 1.5 At an altitude of 10,000 meters. Everyone looked up at the white track in the sky, dumbfounded. At the venture capital meeting, an international friend from Camel Country came to our door curiously, wearing a white headscarf. Lin Yu: "No, no, no, you can't mount anything on the wings. Didn't you buy it back and deliver it by express delivery?" Chen Mo: "It can mount 20 LJ-7s." Lin Yu: "You can't put a guy who can grow mushrooms in the cabin. What are you going to do if you buy them back?" Chen Mo: "It's actually not impossible to let go." Lin Yu: "Chen Mo, are you sure this is for express delivery?" Chen Mo said seriously: "Yes, it's a courier. If someone says otherwise, you can sue him for defamation." An international friend said: "Can we buy a few planes? We have a group of robbers coming here to steal our oil." Chen Mo smiled and said: "One machine has two million green coins and supports scan-code payment."
