After Liu Chang's request was conveyed to the mayor by Tang Kuan, it immediately attracted his attention, and the mayor personally summoned Liu Chang and immediately approved her request after she showed her strength close to the fourth-order evolution. The Wulun Municipal Government undertook the task of escorting Liu Chang to the Suiyuan assessment point this time, and highly recommended it in the official name.

Liu Chang was naturally full of joy and expressed his gratitude to the mayor and Minister Tang.

The city government prepared a sumptuous lunch for Liu Chang and them, and after the meal, accompanied by Minister Tang and the secretary, Liu Chang and Lei Sen came to the transportation field of the Material Exchange Department, and the little girl couldn't help but be stunned by what she saw.

In her imagination before, Wulun City transported its own specialties to Suiyuan for material exchange, and the means of transportation could be trucks, armored vehicles, and trains, but in short, they were all land vehicles, and she definitely didn't expect that people would actually transport them by air!

In the wide square, a row of bright silver huge flying machines stopped there, and it was the first time for Liu Chang to see such strange-looking flying machines, they were not like the common airplanes on earth, nor were they like the saucer-shaped flying objects that were prevalent in the online media. If you have to describe it, it is very similar to the form of a soldier in "Transformers" after transformation, the flat shape has two three-dimensional wingspans in the middle that can act as a cabin, and the designer of the tail is three equally spaced cylindrical structures, Liu Chang did not see gliding tires under the aircraft, and it is initially estimated that this kind of aircraft should be directly ignited and launched like a rocket.

"Minister Tang, sister secretary, thank you again for your help to me, and the little girl will not forget to repay me if I have the opportunity in the future."

When he arrived at the door of the cabin, Liu Chang hugged his fist at the two of them and said solemnly. It's just that her expression is displayed on the delicate girl's face now, but it will only make people feel cute and cute.

The female secretary was amused by her and laughed, "Okay, we didn't think about letting you repay you, if you think about us, you can often come to Wulun to play in the future." ”

"I made a note of it, I'll definitely come to you when the time comes, take care." Liu Chang smiled and waved at them and walked into the cabin.

Lei Sen, who was familiar with him, took Minister Tang's hand and said affectionately: "Minister Tang is thanks to your help this time, thank you for your kindness, I will definitely bring you some Baishan specialties next time I come to Wulun." ”

When Liu Chang and Lei Sen walked in, the two pilots in flight suits were already sitting in the cockpit doing routine pre-flight checks on various instruments. After a few moments, the co-cabin operator instructed them to fasten their seat belts, and then the main cabin operator ignited the fire, and in a loud roar, the tail of the aircraft erupted with blazing flames, and quickly took off into the air.

It is worth mentioning that in the process of the aircraft taking off at great speed, Liu Chang did not notice a sense of weightlessness, and even her body did not have the slightest tilt, I don't know if the aircraft was completely vertically lifted into the air, or if there was any internal adjustment device, in short, in this last world, the advanced degree of science and technology is not what she can understand now.

After hesitating, Liu Chang felt a slight tremor under his feet, and looked up through the porthole to see that the aircraft had already landed on the ground. At the same time, the engine turned off, and the two pilots in the cockpit in front began to unbuckle their seat belts.

"What's wrong? Did something malfunction with the aircraft? Liu Chang asked with a puzzled expression.

"What malfunction? We've arrived. The co-cabin operator unbuckled his seat belt and looked back at Liu Chang, "Sister, it's your first time riding an aircraft, right?" ”

Lei Sen always couldn't change the problem of poor mouth, Liu Chang didn't speak, he took over the conversation and said: "Don't say that it's the first time for her and me to sit on this thing, I only knew that the new government's aircraft are fast, but I didn't expect it to be so fast, Wulun and Suiyuan are at least 700 kilometers apart, and it will be there in the blink of an eye, I'm afraid it won't take a minute, right?" ”

Although Rayson has lived in the last days for three years, as a low-level bounty hunter, he is still in contact with the government's unique advanced equipment for the first time.

Sure enough, it was two dirt buns.

The co-pilot was disdainful in his heart, and he said: "The sailing time is forty-six seconds, the whole journey is 743 kilometers, and the average speed is 15,000 kilometers per second, excluding the buffer phase of starting and landing. ”

Fifteen thousand kilometers, that's not dozens of times more than the speed of sound! The technology of this world is really terrifying!

Liu Chang was suspicious in her heart, but in order not to expose her Xiaobai's essence again, she hid this in her heart and didn't say it.

However, Rayson's eyes widened, and he said with some exaggeration: "Fifteen thousand kilometers per second, which is too fast, I always thought that this kind of aircraft could fly about 10,000 kilometers in an hour." ”

"Tens of thousands of kilometers, do you think it's still in the old times? Now the fastest cars have exceeded 2,000 kilometers per hour, okay? There was a slight mockery in the co-cabin's tone, and he felt that the dirt bun in front of him was too out of step with the times.

The main cabin hand is more modest, he explained on the side: "Actually, it is normal for you not to know this, the last major innovation in aerospace technology was only a few months ago, after the end of the world, the conventional Internet was blocked, the spread of information was slow, and now many people are unaware of this technology." ”

As early as a hundred years ago, during World War II, the German Führer Hitler's secret base had developed an ultra-high-speed saucer, which could rise to an altitude of more than 30,000 meters in one second, more than twice as fast as our current one. At that time, Germany was in the final stages of being encircled by the Allies, so it can be seen that war and a sense of crisis are the best catalysts for technology. ”

For Liu Chang, this sentence is very informative, first she knows the timeline of this world, in the original world, World War II took place in the thirties and forties of the last century, seventy or eighty years from now, and according to the cabin hand, the World War II in this world has passed a hundred years, that is, the time difference between the two worlds is twenty or thirty years. This time difference also just explains the difference in science and technology between the two worlds when Liu Chang first arrived here at the beginning of the apocalypse, and with the outbreak of the apocalypse for three years, under the huge pressure of survival, the world's science and technology exploded, and this gap also increased significantly.

Second, there is the statement about Hitler's secret base saucer-shaped aircraft, she has often seen relevant rumors on the Internet before, but she didn't know that that thing could fly so fast, and it could fly to an altitude of 30,000 meters in one second, which was really unimaginable according to the scientific and technological background at that time.
