The sky is blue and the waning moon is hiding, it is almost dawn. In a factory on the outskirts of Berlin, the street lights are shining, and people are running, as if they are doing the final preparations for things. As the light in the far east increases, a giant cigar with a length of more than 100 meters and a width of the battleship slowly swells on the flat and wide open space; the Hohenzollern family logos sprayed on both sides show the world its unique identity and majesty in this empire.

Accompanied by the slight sound of brakes, Qingying, wearing a strong suit, walked down from the car lately; his young face was a little tired, but his starry eyes were still full of energy. Beside him, when Sunnya saw this big toy, she was extremely excited and smiled like a flower. If it weren't for someone else's presence, she would almost immediately hug Qingying's arm and run forward cheerfully. Originally, Qingying wanted to carefully observe this aircraft that had almost disappeared in later generations, but under Sunnya's coquettish drag, she had to reluctantly choose to directly enter the metal cabin hanging under the airship.

Since this airship was specially customized for the little princess of Sanniya, the girl creature from the Romanov Dynasty arranged the living space of her in an extremely luxurious and luxurious manner. Looking around, it was full of amazing silver jade decorations. After a while, the ground personnel completed the filling of helium and untied the ropes. The airship broke away from the ground in a very stable and elegant manner and went straight to the sky. She threw down the big bed in her room and rolled back and forth, and looked at the little princess who was excited and cheering outside the window and cheered. Qingying stood up and walked into the cab. An old man with two big beards on his lips was staring at the various recording instruments in front of him, which was the old Count Zeppelin who had not seen for a long time. Hearing the sound behind him, Zeppelin turned around and smiled at Qingying.

"Your Highness, you are now riding on the greatest means of transportation on this planet. It has devoted all my efforts to research aircraft over the past thirty years. Whether it is its huge, smooth and powerful appearance, its dreamy airlift weight, its rapid advancement speed or its excellent stable flight, it is absolutely perfect. Thank you for giving me the extremely abundant R&D funds that allow me to fulfill my long-cherished wish and build this gorgeous work of art that does not belong to the current era." Zeppelin bowed slightly to Qingying and said softly in an extremely grateful tone.

Qingying walked to Zeppelin and said, "Mr. Earl, please briefly introduce your masterpiece to me."

"This airship is 102 meters long and 27 meters wide. The 18,000 cubic meters of rare helium filled in 24 airbags not only ensures the absolute safety of the royal crew, but also gives it a theoretical buoyancy of up to 20 tons. It can load all the items they want to carry in the cabin below. In order to ensure structural strength, I have added a lot of internal metal support to this hard airship, which has raised its resistance to bad weather to a new level. In response to the lack of stability of the previous airship, I have also found the reason through a large number of experiments and made extreme improvements on this airship. Your Highness, you should also feel that the airship currently climbing does not have the tendency of head and tail or swaying shaking. It is always sailing forward in an extremely stable posture." Zeppelin stepped on the floor under his feet to show his safety, and then said with a smile.

"In terms of power, it is equipped with two 100 horsepower diesel engines, with a measured maximum stable flight speed of 40.5 knots, which is almost three times that of the first hard airship I built. Compared with traditional passenger trains, its speed is even better and is not limited by any terrain. It can fly in a straight line and travel around all areas at will. The maximum lifting limit of the airship is 3,000 meters, but because it is used for sightseeing, its normal lifting height should not exceed 1,500 meters, according to Your Highness's wish

Please, I have made great efforts in battery life, making the ability to stagnate the airship the biggest highlight of this airship." Zeppelin's energetic eyes were filled with unconcealed comfort and pride, and he said loudly, "As long as the wind speed does not exceed level 6, it can easily stay in the air for 40 hours. If it is a clear and windy weather, its stagnate the airship can be further improved. During the previous five test flights, the airship achieved 2 days of launch time without exception."

Qingying nodded with satisfaction when she heard this. The 2-day activity time and the speed of more than 40 knots will undoubtedly make the airship's range of activity quite wide, enough to carry out long-distance military missions. Even if its dispatch is severely dependent on the weather, it can play a great role in the battlefield. Looking at the rapidly smaller land and mountains beneath her, Qingying suddenly thought of a question and couldn't help but say: "Mr. Earl, can the airship still ensure its maneuverability when the load capacity in the air is greatly reduced?"

Zeppelin was stunned. He then replied: "Theoretically, after the airship is lifted off, the mass will not be allowed to change significantly. Because the air density itself is very small, most of the airspace of the airship itself needs to be distributed to the airbags used to provide buoyancy. The adjustable buoyancy area formed by sucking and discharging the airplane is very narrow. Once the load is thrown away in large quantities after the airplane is lifted off, the airship will rise sharply because the buoyancy is greater than the gravity, and it will get farther and farther away from the ground. At this time, the only solution is to pierce or throw away some of the airbags that provide buoyancy, so that the airship will return to a controllable equilibrium state." Zeppelin's eyes showed a hint of confusion and said in surprise: "What's wrong, Your Highness, why did you suddenly ask this professional question?"

Qingying said nothing, and her face showed disappointment. His eyes were fixed, but he asked back, "Mr. Earl, do you hope that from now on, your airship company will get a steady stream of orders from the army?"

"Of course I want it!" Zeppelin replied without hesitation. Years of scientific research and airship manufacturing have almost exhausted the property he passed down from his count and ancestors. If Qingying had not ordered a airship from him in time, the company founded by the Junker rich man would have been declared bankrupt due to a huge deficit, and he would have to sleep in the bridge hole like those homeless men in another two years! At this moment, Zeppelin finally got a chance to turn the fish over, and he must grasp it firmly; Junkers all have a heart of wealth. In addition to his love for aviation science, Zeppelin expanded his ancestral property is also his long-cherished wish in life.

Qingying smiled and said, "It's great. Since that's the case, please start to solve the problem I just raised. In addition to having good stability, slow speed and long flight time, airships must also have maneuverability after a significant weight reduction to ensure that these cute big cigars can return to the base to land smoothly. Oh, by the way, it should also have certain protection, be immune to rifle bullets, and be able to survive the strafing of machine gun bullets. If Mr. Earl can do this, then the golden mark will be waved to you!"

Zeppelin's pupils contracted, his lips opened and closed, and he said in surprise: "Your Highness, are you trying to..."

"At present, this airship has only completed the first step of militarization and can be used for reconnaissance missions. However, this is obviously far from enough. A slightly larger hard airship can carry more than 10 tons of cargo after deducting its weight. How can such a huge carrying capacity be used well? If all these things can be thrown down in the air, it will have an unparalleled attraction to the military. It is also necessary for the airship to have certain protection. After all, its target is too large. If it has no power to resist the bullets, it will almost lose the meaning of being purchased by the military." Qingying briefly explained.

Zeppelin nodded slightly. Before starting the airship company, he was also a member of the Prussian officers' regiment, so he had a deeper understanding of Qingying's words. If his airship is accepted by the army and ordered in large quantities, he really needs to meet the conditions that Qingying just mentioned. Although these requirements are very strict, this is the field that a military scientist who praises swords and steel in his bones is addicted to. What's more, the current scientific research funding has already paid for him, and there is no restraint on the objective conditions. The long long beard on his lips raised up, and he said: "To be honest, the realization of this idea is more difficult than balancing the airship and increasing the time of stagnation in the air. However, as long as Your Highness always provides research and development funds, I am very happy to continue to climb the top on the road of science!"

Leaving the cab and entering the living room, his warm and soft body suddenly entered his arms in one fell swoop, and all he could smell was familiar fragrance. Because of the flight toy he had dreamed of, Sunnyya was in a good mood and rubbed her head against Qingying's neck like a cat. He gently stroked the little princess's soft and smooth blonde hair, and was about to keep warm, when a few words suddenly burst into bright morning light.

A red sun jumped out from the horizon far away in the east, with a vast and flat fertile field shining on the vast and flat fields. The rivers lingered in jade, the wheat waves surging, the birch stood up, and the fields were connected. Horses neighed, cattle and sheep sang, goshawks spread their wings, and birds floated. The hardworking and kind farmers walked out of the houses that were decorated with scattered drifts and began a day of field work under the bath of the brilliant morning light.
